To Bill<br />

Acknowledgments<br />

This book is essentially a distillation of ten years of teaching<br />

nutrition to naturopathic students. I would like to acknowledge<br />

my good friend Linda van Niekerk, and my good<br />

husband, Bill Alldritt, for suggesting I create a book from<br />

these lectures.<br />

I am deeply appreciative for the help and advice I have<br />

received from the following people: Lorna Scott, Kerrie<br />

Murrell, Dannae Brown, Doris Alldritt, Craig Ashley-Russell,<br />

Lyn Crossley and Phil. Thankyou.<br />

Special thanks to my publisher, Stuart Neal, for making<br />

the book writing process as painless as possible.


Introduction<br />

I have some very smart patients. Sick, but smart. It always<br />

surprises me how these intelligent, creative, successful<br />

people often do not have a clue about good nutrition. Oh,<br />

they might murmur knowingly about the benefits of omega-3<br />

fatty acids; but when questioned will sheepishly admit to<br />

being flummoxed. They are not alone! In my 10 years of<br />

teaching in naturopathic colleges, I have found a mass of<br />

con-fusion. What is the difference between a legume and a<br />

grain? Is a legume the same as a bean? Should I care? Why<br />

do beans give me flatulence? Other questions include: Why<br />

aren ' t six cups of coffee equivalent to six cups of water?; and<br />

Why do I feel tired after lunch? Let alone knowing the<br />

intricacies of fatty acids. In fact, it takes quite a lot of<br />

background information before one understands that an<br />

omega-3 fatty acid is scientist-speak for a chain of carbons<br />

<strong>with</strong> the first double-bond occurring on the third carbon from the<br />

methyl end. No wonder people get confused!<br />

Nearly every magazine and infotainment program has<br />

something to say about diet and nutrition. Unfortunately, the<br />

information is often contradictory. For example, take the<br />

maxim `Cholesterol is bad ' . In fact, cholesterol is not bad.<br />

Cholesterol is vital. Did you know that from cholesterol the<br />

body makes oestrogen, phospholipids necessary for brain<br />

function, vitamin D and the stress hormone cortisol? It<br />

doesn ' t help to see avocados proudly sporting `no cholesterol '<br />

labels when the poor green darlings don ' t possess a liver <strong>with</strong><br />

xi

The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

which to create cholesterol in the first place. And what's<br />

more, for most people, their blood cholesterol levels have<br />

nothing to do <strong>with</strong> how much cholesterol they eat.<br />

All this makes me angry and an angry naturopath is a terrible<br />

thing. To ease my anger I have written this book. I hope<br />

it gives you easy-to-digest information and the inspiration to<br />

look after your diet and yourself. After all, you are what you<br />

eat.


THE GEOGRAPHY<br />

OF NUTRITION


f-cm<br />

DESCENDING COLON


The Digestive Tract<br />

How the worm turns<br />

In a book about nutrition, why are we discussing the digestive<br />

tract? Basically, the best nutrition will come to nought if your<br />

digestive tract is not up to scratch. The digestive tract, also<br />

known as the alimentary canal or gastrointestinal tract (GIT),<br />

is simply a hollow tube. Much like an earthworm, the tube<br />

is open to the world at both ends - mouth and anus. It is the<br />

interface between the food we eat and our body; essentially,<br />

the geography of nutrition.<br />

Our body is fashioned around this tube. In order for the<br />

saying 'you are what you eat' to be true, what you eat needs<br />

to make the hazardous journey across the wall of the intestine,<br />

into the bloodstream. Until this time, food in the tube<br />

has not been absorbed. What is inside the digestive tract, is<br />

outside you - strange but true.


4 T&e Commonsense Gaide to <strong>Eating</strong> <strong>Well</strong><br />

A brief overview<br />

The GIT begins at the mouth, transforming into the oesophagus,<br />

then the stomach, followed by the small intestine, large<br />

intestine, rectum and anus. The muscular tube is essentially<br />

the same structure throughout, however the terrain changes<br />

according to a 'need to digest' basis. For example, the<br />

stomach lining looks very different from the lining of the<br />

small intestine. The former is thickly coated <strong>with</strong> acidresistant<br />

mucus; and the latter looks like a 1970s shagpile<br />

carpet. On average, the digestive tract is 9 metres long,<br />

roughly as long as two decent-sized loungerooms. Quite a lot<br />

of tubing to fit into the short distance from face to fanny.<br />

The Digestive Tract 5<br />

In conjunction <strong>with</strong> the GIT, other structures including the<br />

pancreas, liver, gall bladder, teeth and salivary glands are<br />

needed for the digestive system to function. These ancillary<br />

organs of digestion are attached to, but do not form part of,<br />

the tubing.<br />

The ins and outs<br />

The digestive tract has several functions. The first is ingestion,<br />

being the act of taking food or liquid into the body,<br />

which occurs at the top of the tube, the mouth. The second<br />

function is to facilitate movement along the tube. The wavelike<br />

muscular motion, which pulses in a downward direction,<br />

is called peristalsis. If animals relied on gravity alone for food<br />

to pass along the digestive tract, many a cow or other grazing<br />

animal would be in big trouble, as their mouths are pointing<br />

downwards most of the time.<br />

Function number three gets to the guts of the matter,<br />

digestion. Digestion is the process whereby we break food<br />

down into smaller and smaller bits. The first stage of digestion<br />

is mechanical in nature, where we physically grind the<br />

food <strong>with</strong> our teeth and churn it <strong>with</strong> the thick muscly walls<br />

of the stomach. The next stage of digestion is chemical, taken<br />

care of by digestive enzymes. These enzymes convert the<br />

fragments of food into little itty-bitty bits, small enough to<br />

cross the intestinal wall.<br />

Function four is absorption, the passage of digested food<br />

across the digestive tract into the bloodstream, eventually for<br />

distribution to all parts of the body. If a food is not absorbed<br />

across the intestinal wall, it will continue on downwards and<br />

eventually out the other end of the tube. Of course, the food<br />

needs to be broken down into small enough bits in order to<br />

hurdle across. Protein is broken down into amino acids. Fat


6 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

is broken down into glycerol and fatty acids, and carbohydrate<br />

is broken down into simple sugars. Fibre, which is a form of<br />

carbohydrate, is unable to be broken down and therefore<br />

cannot be absorbed.<br />

The final function of the digestive tract is that of defecation.<br />

Allowing indigestible substances and waste products to<br />

leave the body is an important process of elimination.<br />

A closer look<br />

Taste sensations<br />

I spent a good half of my childhood glued to the television set<br />

watching the Flintstone family. My interest in the evolution of<br />

eating habits probably stems from these times <strong>with</strong> Fred,<br />

Barney, Wilma and Betty. Another favourite, the Jetsons,<br />

seemed, in the 1960s, a plausible if dysfunctional family of the<br />

near future. It made me believe that by 1969 (at the latest), we<br />

would all be eating food pills containing all the nutrients our<br />

bodies required - and we did, in trips to the moon.<br />

There are over 10 000 tastebuds dotted over the tongue.<br />

They clump together in groups of 40 to 60 cells into projections<br />

called papillae that we call tastebuds. Each bud is penetrated<br />

by nerve fibres, which are able to transmit information<br />

about chemicals in food to the brain, which in turn translate<br />

this into taste. Although the tastebuds are scattered over the<br />

tongue, there appear to be several areas of taste concentration,<br />

<strong>with</strong> the sweet buds located around the tip of the<br />

tongue, sour on either side, bitter at the back and salt somewhere<br />

in the middle.<br />

Tastes escape from our tongue into our language: 'how 1<br />

sweet life is'; 'she's a sour puss'; 'what a bitter pill to swallow';<br />

'Bill is the salt of the earth'.<br />

Why the Jetson's all-you-ever-needed-in-a-pill didn't take


The Digestive Tract 7<br />

off is that it lacked taste and smell. Our sense of smell is<br />

linked <strong>with</strong> our emotional and memory centre, located in the<br />

hippocampus in the brain. Certain smells trigger emotions,<br />

like the smell of bacon and eggs on a Sunday morning (particularly<br />

if you are an Aussie male) or freshly cooked bread.<br />

Like Pavlov's dog, exactly the same reflex principle applies<br />

to human animals. Digestive juices begin to flow when the<br />

brain detects a wholesome foodsmell. If you feel well, you<br />

digest well.<br />

Taste provokes a stronger message than smell. Tastebuds<br />

that line the tongue are literally nerve endings, ultimately<br />

triggering other nerves to get the digestive show on the road.<br />

The major players are sweet, sour, salty and bitter. Other<br />

contenders include pungent, alkaline (soapy), metallic (the<br />

coppery taste of blood) and umame, which translates from<br />

the Japanese as yummy (a taste that monosodium glutamate<br />

accentuates and is found mainly in meat). Each taste has its<br />

own shade and nuance.<br />

Acid<br />

During my first term of studying Economics at Sydney<br />

University, I took a Wine Appreciation Course that was held<br />

each Tuesday lunchtime, just before the Statistics 1 lecture. I<br />

failed Statistics that year. (As an accountant I make a good<br />

naturopath!) Nevertheless, it is an ill wind that blows nobody<br />

good . . . The course tutor set up a series of glasses containing<br />

distilled water. To each glass he added a drop of acid. A drop<br />

of tartaric acid in one, a drop of malic acid in another. We<br />

students took a sip from each glass, noticing which part of the<br />

tongue was affected by the sourness. The taste was strongest<br />

at the sides of the tongue, <strong>with</strong> malic acid below the tartaric.<br />

Malic acid is more predominant in cooler climate grapes, tartaric<br />

acid in warmer - we could now show off at dinner parties.<br />

There are hundreds of different types of acids and other


8 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

compounds in many types of foods, not only wine. It stands<br />

to reason that there would be an equal diversity in sweetness,<br />

bitterness and even saltiness.<br />

Sweet, sour, salty and bitter<br />

One can't ask one's tongue why there are different tastes, so<br />

any reason given is pure conjecture. Children, in particular,<br />

like sweet things. It could be because of an association <strong>with</strong><br />

mother's breast milk that has a relatively high sugar (lactose)<br />

content. In addition, sweet fruit contains vitamin C. Humans<br />

cannot make their own vitamin C, yet require it daily.<br />

Perhaps we developed a liking for sweetness, which in nature<br />

supplied us <strong>with</strong> this valuable vitamin. Unfortunately, sweet<br />

foods today, like chocolate bars, rarely contain vitamin C.<br />

Another reason why it may be evolutionarily sound to be able<br />

to detect sweetness, is that many carbohydrate foods are<br />

sweet and carbohydrate is our major source of energy.<br />

The tastebuds that register sour and bitter have a powerful<br />

effect on nerves supplying the digestive system, particularly<br />

to the liver. To help stimulate a sluggish digestive system, I<br />

often recommend a morning glass of hot water <strong>with</strong> either a<br />

teaspoon of apple cider vinegar or the juice of half a lemon<br />

(both are sour), or a predinner drink of bitters in water. Bitter<br />

foods have taken a low profile of late, which is a shame as they<br />

can be powerfully medicinal - also stimulating liver function.<br />

Examples of bitter foods include radicchio (red lettuce), cress,<br />

rocket, olives, bitter melon, grapefruit and coffee.<br />

There are as many savoury tooths as there are sweet tooths.<br />

Salt is an important substance for the body, needed for many<br />

biological functions, including fluid balance. It is a shame that<br />

salt has become so easy to overdo. We can obtain all the salt<br />

our body needs by eating well. There is no need to add extra,<br />

although, if you like (and your diet is low in processed foods),<br />

you could supplement <strong>with</strong> a little sea salt or natural soy sauce.


The Digestive Tract 9<br />

Surprising saliva<br />

We produce about 1 to 1.5 litres of saliva daily. Quite a lot of<br />

spit, you'll agree. Water makes up 99.5 per cent of saliva, moistening<br />

the food sufficiently so that it doesn't scrape on the way<br />

down. The remaining 0.5 per cent is full of surprises. A couple<br />

of enzymes lurk in saliva: ptyalin (<strong>with</strong> a silent 'p') starts the<br />

breakdown of carbohydrate, whereas another enzyme, lysozyme,<br />

is responsible for killing bacteria. Mucin, also present in<br />

saliva, helps lubricate the chewed food, so it literally slips down<br />

the throat. Sodium, potassium and bicarbonates are also present<br />

to balance the pH, which needs to be slightly on the acid side<br />

of neutral (see pHocus on pH, page 10).<br />

Speed eating<br />

Chewing sends a message to the brain that dinner is about<br />

to be served. The brain then transmits this information to the<br />

organs of digestion. If we don't chew, the digestive juices<br />

don't flow and peristalsis slows down. If we don't chew properly,<br />

big pieces of food are going to travel down the digestive<br />

tract and end up in the lower bowel, where they become food<br />

for bacteria, producing gas. If you suffer bloating and flatulence<br />

the first thing you need to do is chew.<br />

There are entire families of speed-eaters. Speed eating is<br />

a lifelong habit and is usually passed down through the generations.<br />

Like any habit, speed eating is difficult to break.<br />

One tip is to put down your knife and fork between each<br />

mouthful to remind yourself to chew.<br />

If a patient walks into my consulting room chewing gum,<br />

I grab a tissue and ask them to spit their gum into the tissue.<br />

If you are not about to eat a meal, don't chew. Chewing gum


I0<br />

The Commo~rsense G de to <strong>Eating</strong> <strong>Well</strong><br />

sends mixed messages to the digestive system and is responsible<br />

for many a bloated tummy and a few stomach ulcers.<br />

Stomach acid: double, double, toil and trouble<br />

Once food gets to the stomach it should be nicely chewed up<br />

and look soupy. The stomach is a muscle-bound organ, about<br />

the size of your fist. It is designed to churn the food around<br />

and mix it <strong>with</strong> the powerful digestive fluid, hydrochloric acid.<br />

Hydrochloric acid (see pHocus on pH, below) is designed to<br />

kill bacteria and other germs, as well as begin the process of<br />

protein digestion. If the acid is strong enough, around pH 1.2<br />

to 3.0, the enzyme, pepsin, will be activated to break down the<br />

bonds joining protein chains together, and the even finer work<br />

of separating amino acids from one another by snipping peptide<br />

bonds. A 3 millimetre thick lining of mucus protects the<br />

stomach wall from being damaged by the acid.<br />

A pHocus on pH<br />

There's more to pH than hair conditioners. pH stands<br />

for hydrogen potential and is a nifly way to measure<br />

acidity. The more hydrogen ions there are, the more<br />

acidic it is. The scale swings from very very acid at 0, to<br />

very very alkaline, the opposite of acid, at 14. Neutral is<br />

7: neither acid nor alkaline. Levels closer to 0 on the<br />

scale are more acidlc: 6 is more acid than 7. However,<br />

6 is not just one time more acidic, but 10 times more<br />

acidic than 7. A change of one whole number on the<br />

pH scale represents a 10-fold change.<br />

The Digestive Tract<br />

I<br />

pH is all very well, but what has it got to do wfth me?<br />

Maintaining the correct pH is one of the most important<br />

jobs the body has to do. If the pH of our blood varies<br />

by as little as 0.5 to pH 7.0 or 8.0 we are in serious<br />

trouble, courting acidosis or alkalosis. Luckily, the body<br />

is veq good at keeping pH levels <strong>with</strong>in acceptable<br />

parameters. The body needs to maintain stable pH<br />

levels for blood, saliva, inside and outside cells, semen,<br />

stomach and pancreatic juice.<br />

Stomach add<br />

As this book is about nutrition, it seems reasonable to<br />

focus on the pH of our digestive juices. Stomach acid is<br />

wicked acid, as you can see from the table on the next<br />

page, it bubbles away at around a pH of 1.2 to 3.0. If<br />

you were to accidentally spill a couple of drops of<br />

stomach acid on your arm, it would bum the flesh away.<br />

Ouch. We need it to be so acidic to break some of the<br />

bonds holding protein strands together. Also, acid that<br />

powerful is an excellent death trap for bacteria and other<br />

germs. In fact, if stomach acid is not add enough (a<br />

condition called hypochlorhydria) , protein is inadequately<br />

digested. This can cause digestive problems,<br />

such as bloating, as well as increasing the likelihood of<br />

food allergies, as partially digested protein fragments are<br />

absorbed thereby setting up an immune response in the<br />

body. Another down side of insufficient stomach acid is<br />

lack of zap power. Bacteria, &uses et a1 have a greater<br />

chance of surviving and setting up shop lower down the<br />

bowel. People <strong>with</strong> low stomach acid are more likely to<br />

suffer food poisoning and travellers' bowel. Other signs<br />

of low stomach acid include peeling and weak fhgernails,<br />

burping a lot, flatulence, abdominal bloating,


1.2 T&e Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

feeling very full after not-so-big meals and dry lips all<br />

the time.<br />

A teaspoon of herbal bitters in water before dinner,<br />

or a digestive tablet containing hydrochloric acid <strong>with</strong><br />

each meal can help restore underactive stomach acid.<br />

Very rarely do people suffer from an excess of<br />

stomach acid. Symptoms such as refIux or heartburn<br />

may feel like there is too much acid, but it is more the<br />

case of acid being in the wrong place at the wrong time.<br />

Similarly <strong>with</strong> stomach ulcers, the acid should not have<br />

been able to penetrate the protective mucus lining in<br />

the fust place. Stomach ulcers are more often the fault<br />

The Digestive Tract 13<br />

After departing the stomach, the ex-meal is jettisoned into<br />

the first part of the small intestine, the duodenum. It is now<br />

called chyme, not as in doorbell but as in crime. Immediately,<br />

we need damage control. The chyme, which is highly acidic,<br />

has been dumped into a part of the body, the duodenum,<br />

which (unlike the stomach) is ill-equipped to deal <strong>with</strong> high<br />

acid. Alkaline, digestive secretions from the pancreas and gall<br />

bladder buffer the acid to acceptable levels.<br />

The pancreas is an ice-cream cone shaped organ that<br />

spends its life lurking behind the stomach. Around meal-time<br />

it becomes a hive of activity, on one side excreting pancreatic<br />

juice into the digestive tract and on the other secreting<br />

insulin into the bloodstream. The pancreas produces valuable<br />

digestive enzymes and alkaline fluid (bicarbonate) that are<br />

collectively delivered into the small intestine. There are pancreatic<br />

enzymes for every occasion: enzymes for the digestion<br />

of fat called lipase; enzymes for the digestion of carbohydrate<br />

called amylase; and enzymes for the digestion of protein<br />

called protease. These digestive enzymes are able to break<br />

down fat, carbohydrate and protein into small enough units<br />

to be able to be absorbed across the wall of the small intestine<br />

into the bloodstream.<br />

Bile: digestive detergent<br />

The gall bladder is a sac that carries bile, a greeny brown<br />

liquid made by the liver. Bile is an example of recycling in<br />

action as it is part waste product, part digestive secretion.<br />

Imagine you are at a barbecue. The scene: 1977. The day<br />

is Sunday. Early January. It is stinking hot. There are several<br />

late model Monaros parked on the wilting grass. The music:<br />

Boz Scaggs. Coleslaw in parquet bowls, garlic bread wrapped<br />

in foil, potato salad and chops and sausages on the barbie.

Unfortunately you are washing up. You are not environmentally<br />

aware; you cannot throw the plates away - they are<br />

your mother's plastic picnic plates and she wants them back,<br />

clean. The three choices are:<br />

1. wash the plates under the cold water tap;<br />

2. wash them under the cold water tap <strong>with</strong> detergent; or<br />

3. wash them in hot water <strong>with</strong> detergent.<br />

Left to its own devices, fat tends to blob. Mixing it <strong>with</strong><br />

cold water only serves to make things worse, whereas hot<br />

water melts the fat. Detergent disperses fat into tiny droplets<br />

that are easier to deal <strong>with</strong>. This process is called emulsification.<br />

Choice 3 is the correct answer.<br />

If we return to the small intestine, we have a similar situation.<br />

It is very warm (body heat) and bile from the gall<br />

bladder acts as a digestive detergent, emulsifying the fat into<br />

smaller droplets. These droplets are small enough so that<br />

lipase, the fat-digesting enzymes from the pancreas, can<br />

break down the fat into fatty acids and glycerol. Then they<br />

can be absorbed across the intestinal wall.<br />

Villi: the coal face of digestion<br />

The small intestine is where virtually all digestive action<br />

happens. The small intestine is 6.4 metres long and is small<br />

in diameter, roughly 2.5 centimetres. It folds on itself like a<br />

slippery snake and takes up a fair amount of space in the<br />

abdomen. The first part of the small intestine, the duodenum,<br />

is where most absorption occurs, although there are<br />

opportunities down the entire length, including the jejunum<br />

and the ileum that joins the large bowel. The nutrients, fatty<br />

acids, glycerol, amino acids, glucose, vitamins and minerals<br />

cross over the thin layer of cells into the bloodstream. The<br />

majority of these nutrients follow the portal vein that takes


The Digestive Tract 15<br />

blood straight to the liver where they will be sorted out and<br />

sent on to wherever they are needed.<br />

The topography of the small intestine consists of fmgerlike<br />

projections called villi. Each villus is only a<br />

pis up wiH\ the<br />

pcrtal vein whih )q<br />

nkienk 6 +he / i v ~<br />

couple of cells thick and is where nutrients are absorbed<br />

into the bloodstream. The villi are the coal face of digestion.<br />

These villi are custom made to increase the surface<br />

area of the small intestine. Some dedicated scientist<br />

(<strong>with</strong> a very small tape measure) measured up and<br />

down each villus for the entire 6.4 metres and calculated<br />

that the area for absorption is similar to the expanse of<br />

a football field.<br />

Amino acids, short-chain fatty acids, glycerol and<br />

glucose enter the vende (small vein) that joins up to the<br />

portal vein that goes to the liver. Because of the logistical<br />

problems of mixing fat in a watery environment, longchain<br />

fatty acids form into little packages called micelles<br />

and later chylomicrons that travel in the lacteal (central<br />

vessel in the villus), which is in fact an outpost of the


16 The Commonsense Guide to <strong>Eating</strong> WeZZ<br />

lymphatic system. The chylomicrons eventually enter<br />

the bloodstream, go to the liver and are then transformed<br />

into lipoproteins. The arteriole, a small artery,<br />

feeds the cells of the villus <strong>with</strong> nutrients and oxygen.<br />

The end of the tunnel<br />

The large bowel is much shorter than the small intestine,<br />

around 1.5 metres long, but it is much wider, 6.5 centimetres<br />

in diameter. At the end of our digestive journey, over 90 per<br />

cent of digestion has occurred by now. A few micronutrients<br />

and some water can be absorbed from here but the large<br />

bowel is not set up for absorption.<br />

The large bowel hangs in an upside down 'U', starting from<br />

the right-hand side where it joins the small intestine at the<br />

ileo-caecal valve, up the ascending colon, across the transverse<br />

colon and down the descending colon on the left-hand<br />

side. The rectum is where faeces are stored before they exit<br />

Abdominal massage can be very helpful for people who<br />

are constipated, suffer pain from the likes of diverticulitis,<br />

or just hold stress in their bowel. Lie down on your<br />

back, <strong>with</strong> your head on a pillow and a pillow under<br />

your bent knees - this will take any muscular tension<br />

away from the tummy. With the pads of the fingers of<br />

one hand, slowly and deeply, massage in small circles<br />

from the right-hand side above your hip, following the<br />

direction of the bowel. If there is any pain, ease up and<br />

then go back <strong>with</strong> a gentler motion. This massage can<br />

be done <strong>with</strong> warm oil or talcum powder.


Tde Digestive Tract 17<br />

via the anus. Throughout the entire digestive tract! there are<br />

literally billions of microorganisms, many of which are<br />

beneficial to our wellbeing (see probiotics box, page 34).<br />

Faeces are 75 per cent water and the rest is made up of<br />

bacteria (mostly from the bowel itself), fibre and sloughed off<br />

cells from the intestinal tract. Australians, among others, are<br />

a timid lot when it comes to talking about poo. Although<br />

there are enough scatological jokes to fill a library, few of us<br />

are willing to speak openly about something that is part of<br />

everyday life. This is unfortunate, as one can learn a lot from<br />

droppings; not least how well we are digesting our food. My<br />

first practical understanding of this came soon after I graduated.<br />

I had found work <strong>with</strong> a large vitamin company where<br />

one of my jobs was to answer letters from customers. Mrs P<br />

had written to complain about the quality of one of our<br />

vitamin pills. In case we felt inclined to doubt, she had kindly<br />

returned the tablet in question, fastidiously wrapped in toilet<br />

paper, after being retrieved from the loo. After recovering, I<br />

wrote to Mrs P tactfully pointing out that the problem was<br />

not <strong>with</strong> our vitamin pill, but <strong>with</strong> her digestive system.<br />

On a more serious note, bowel cancer is one of the most<br />

common forms of cancer. A change in bowel habits or the<br />

sign of blood could be early warning signs of this deadly<br />

disease (more often than not red blood is the sign of a haemorrhoid<br />

or small fissure, but it is silly not to investigate). It<br />

is a tragedy that we find it difficult to talk about this natural<br />

process of life openly and free from embarrassment.<br />

A fart is predominantly hot air expelled from the anus,<br />

whereas a burp is air released from the other end.<br />

Flatus, a posh word for fart, is a mixture of carbon<br />

dioxide, hydrogen and methane <strong>with</strong> various quantities<br />

of aromatic substances including hydrogen sulfide


18 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

(rotten egg gas), indole, skatole and arnrnonia (smells<br />

like tomcat wee). On average, we expel half a litre per<br />

day. Flatus arises from two causes. The first is the result<br />

of swallowing too much air. Fast eaters and fast talkers<br />

may find they need to expel excess air. The same may<br />

be true for mouth-breathers, those for whom the option<br />

of nostril breathing is blocked, including sinus sufferers<br />

and snorers. The other cause is home-grown. Of the<br />

bions of bacteria that inhabit our digestive tract, by far<br />

the majority live in the large intestine. Many produce gas<br />

as a by-product. Poor digestion is oAen the cause of<br />

flatulence and bloating, as the bacteria feast on food that<br />

has not been digested in the small intestine and has<br />

travelled down to the large bowel.


ESSENTIALS


Carbohydrates:<br />

Fuel and Fibre<br />

The word carbohydrate to many people conjures up plates of<br />

pasta, mashed spuds and rice. While these are carbohydraterich<br />

foods, the world of carbohydrates extends to fruits, vegetables,<br />

honey, sugar and fibre.<br />

Classification<br />

Humans love to classify things. Horoscopically: Aries or<br />

Pisces; racially: Chinese or Greek; religiously: Jewish or<br />

Buddhist. Carbohydrates are classified according to the<br />

complexity of their chemical structure. The least complicated<br />

structures, one or two units, are called 'simple' carbohydrates<br />

and the more elaborate structures, up to thousands of units,<br />

are called 'complex' carbohydrates.


22 The Commonsense Gzcide to Bating <strong>Well</strong><br />

From the humblest to the most grandiose carbohydrate<br />

there are only three elements involved: carbon (C),<br />

hydrogen (H) and oxygen (0). Fie or six carbons jointo<br />

form rings, the oxygen and hydrogen just hang<br />

off these rings. The most common is the six-carbon<br />

structure, or hexose (hex-six, ose-sugar). And the three<br />

common hexoses in food are glucose, galactose and<br />

fructose, <strong>with</strong> glucose greatly outnumbering the other<br />

two.<br />

If you join two monosaccharides together, you have a disaccharide<br />

(di-two, saccharide-sugar). Joining glucose + glucose<br />

= maltose (the breakdown product of starches); glucose +<br />

fructose = sucrose (table sugar); and glucose + galactose =<br />

lactose (milk sugar).<br />

Glucose is our body's major fuel. Virtually every cell lives<br />

for and by glucose. Without glucose we die. However, in<br />

nature, glucose per se is rarely found. Rather, it is complexed<br />

<strong>with</strong> other simple sugars. As a consequence, our physiology<br />

has adapted to prefer complex carbohydrates.<br />

Complex carbohydrate no. 1: Starch<br />

Only plants contain starch, particularly grains, beans, seeds,<br />

nuts, some vegetables and fruits. A cubic inch of a starchy<br />

food like potato contains a million starch molecules. Carbohydrates<br />

should be about 65 to 70 per cent of our diet, <strong>with</strong><br />

much of it in the form of starch. We may eat starch, but in<br />

order to utilise the fuel, glucose, we have to break the<br />

complex carbohydrate into single-unit sugar molecules, predominantly<br />

glucose.


Carbohydrates: Fael and Fibre 23<br />

Complex carbohydrate no. 2: Glycogen<br />

Glycogen is the second type of complex carbohydrate. It is<br />

how the human body stores glucose. Sometimes called<br />

'animal starch', glycogen does not occur in plants. We store<br />

most of it in the liver (up to 400 grams) as well as in the<br />

muscles (up to 100 grams). Glycogen is stored as ready<br />

energy. Like going to the store for food, if insufficient glucose<br />

is available from the bloodstream, it can be obtained by<br />

breaking down stored glycogen.<br />

Complex carbohydrate no. 3: Ffbre<br />

The third type of complex carbohydrate is fibre (also see<br />

fibre, page 29). At first glance under the microscope, fibre<br />

looks very similar to starch - a large group of glucose molecules.<br />

Upon closer examination the dissimilarity becomes<br />

apparent: the bonds holding the glucoses together in starch<br />

are different from the bonds holding the glucoses together in<br />

fibre. Humans don't possess the specific enzymes to untie<br />

these bonds, so the fibre continues down the digestive tract<br />

undigested. Cows and other animals have these enzymes in<br />

their rumen which explains why a horse can enjoy a square<br />

meal of hay and we can't.<br />

Glycaemtc index<br />

The glycaernic index is a ranking of foods based on their<br />

immediate effect on blood sugar levels. The greater the<br />

index, the quicker and higher blood sugar levels rise.<br />

Glucose is the gold standard at 100. Blood sugar levels<br />

are important for many things, including brain function,<br />

energy levels, insulin production and mood.<br />

Not all sugars are created equal. Glucose readily<br />

crosses over the intestinal wall into the bloodstream.<br />

The other single sugars vary in the speed at which they


'<br />

24 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

I<br />

cross this barrier, <strong>with</strong> fructose taking more than double<br />

the time of glucose and galactose skipping over 10 per<br />

cent faster.<br />

This recently acquired information has thrown the<br />

nutritional world into a tizz. In the past, everyone<br />

thought that complex carbohydrates have a slower<br />

impact on blood sugar levels than simple carbohydrates.<br />

Not so. For instance, take fructose, a single sugar, which<br />

has a glycaemic index of 23 compared <strong>with</strong> bread, a<br />

starchy food, which has a glycaemc index of 75. A total<br />

reverse of what we formerly thought. This information<br />

has had the greatest influence on diabetics, a disease<br />

whose nutritional world revolves around taking insulin<br />

according to levels of blood sugar. Who would have<br />

guessed that honey has a more moderate effect on<br />

blood sugar than parsnips or baked potato?<br />

There are several factors thought to affect glycaemic<br />

index, including fibre, anti-nutrients such as phytates<br />

and tannins, acidity, fat and protein.<br />

Although the glycaemic index presents us <strong>with</strong> some<br />

fascinating information, it is important to realise that the<br />

index is relevant to that food eaten in isolation. Something<br />

that rarely happens. We tend to eat foods like<br />

baked potato <strong>with</strong> other things like meat and peas, and<br />

these other foods bring down the glycaemic index to<br />

less panicky levels.<br />

What happens to glucose in the bloodstream?<br />

Once the sugar molecule (whether it came from a jellybean<br />

or a baked bean) crosses the intestinal wall, it is swept into<br />

a fast-flowing river of blood (portal circulation) taking all the


Carbohydrates: FzleZ and Fibre 25<br />

nutrients of digestion straight to the liver to be sorted and<br />

recirculated. If there are any toxins, the liver will hopefully<br />

be able to detoxify them before they are allowed to recirculate.<br />

After a meal, glucose is absorbed into the bloodstream<br />

and blood glucose levels will increase. A part of the brain,<br />

the hypothalamus, keeps a check on the amount of glucose.<br />

If it exceeds or falls below a particular range, orders are issued<br />

to set things right. The average amount of sugar circulating<br />

at one time is 20 grams, or four teaspoonsful. So you can see<br />

that there is not a lot of room to play around <strong>with</strong>. If something<br />

is wrong <strong>with</strong> the regulation, sugar in the blood can<br />

remain too high, as in the case of diabetes.<br />

Hypoglycaemia<br />

Hypoglycaemia cited in medical texts literally means<br />

'low (hypo) blood (aemia) sugar (glyc)', where the circulating<br />

blood sugars stay below normal levels for a prolonged<br />

period. This can be life-threatening and is usually<br />

drug or alcohol induced. On the other hand, the hypoglycaemia<br />

that natural therapists frequently diagnose, is<br />

a condition of fluctuating or seesawing blood sugar<br />

levels. Symptoms of this include exhaustion, depression,<br />

anxiety, irritability, mood changes, headaches, dizziness,<br />

sweating, tremor, fast heart beat (tachycardia),<br />

muscle pain and weakness, conksion, forgetfulness,<br />

sweet craving, reduced libido, excessive hunger<br />

between meals, waking exhausted, nausea before<br />

meals, tired after lunch and craving sweets, coffee, cigarettes<br />

and alcohol. Most symptoms improve after<br />

eating, reflecting an increase in blood sugar.<br />

The following factors contribute to hypoglycaemia:<br />

Missing meals, especially breakfast. By the time you<br />

eat lunch it could be 16 or 17 hours since last night's


26 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

dinner. You have effectively entered a fasting state, <strong>with</strong><br />

low blood sugar levels.<br />

• A sweet tooth.<br />

• High glycaemic index foods eaten on their own. The<br />

glycaemic index (GI) ranks foods according to how<br />

quickly they raise blood sugar levels. Foods <strong>with</strong> a high<br />

GI, that is, between 70 and 100, will increase<br />

blood sugars faster and higher than foods <strong>with</strong> a low GI.<br />

• Substances that cause a rapid and unsustained rise in<br />

blood sugar levels include caffeine (coffee, cola and<br />

guarana), nicotine and alcohol.<br />

• Stress causes an increase in adrenalin that raises blood<br />

sugar levels.<br />

• Deficiencies in the vitamins and minerals which are<br />

necessary for sugar metabolism are bound to cause<br />

problems <strong>with</strong> sugar metabolism. The nutrients in<br />

question include zinc, chromium, calcium, magnesium,<br />

manganese and vitamins B1 and B3.<br />

What to do<br />

The treatment of hypoglycaemia is easy and results can be<br />

felt <strong>with</strong>in a few days.<br />

• Eat small meals, regularly: breakfast, morning tea,<br />

lunch, afternoon tea, dinner and supper.<br />

• Each meal should contain a little protein and high fibre<br />

carbohydrate - for example, cheese and wholemeal<br />

bread, brown rice and dhal, beans on toast, egg and toast,<br />

tuna and rice, fish and salad.<br />

• Eat plenty of fibre. Fibre slows down the rate at which<br />

sugar is absorbed.<br />

• Avoid the triggers sugar, alcohol, coffee, cigarettes.<br />

• Foods which are particularly good for stabilising blood


Carbohydrates: Fuel and Fibre 27<br />

sugar levels include apples, blueberries, rye, oats,<br />

green beans, fenugreek and beans.<br />

Take a B-complex each morning or a tablespoon of<br />

brewer's yeast. Brewer's yeast has the advantage of<br />

containing chromium, an important mineral in sugar<br />

metabolism.<br />

Once the glucose is absorbed into the bloodstream, it<br />

becomes known as blood sugar or blood glucose. Much of it<br />

enters cells where it will be converted into energy via a series<br />

of chemical reactions known collectively as the Krebs cycle<br />

(see box below). Every cell needs energy to do its job. Muscle<br />

cells use energy to move us around, lung cells use energy to<br />

accept oxygen. Every cell uses energy for its own health, as<br />

well as fulfilling its role in the body. The favoured fuel for<br />

cell energy is glucose. Glucose passes from the blood across<br />

the cell membrane and into the cell <strong>with</strong> a small push from<br />

the hormone insulin.<br />

Exactly how do I get energy from food?<br />

The Krebs cycle<br />

Nothing worthwhile is ever easy. After we go through all<br />

the palaver of digesting our food, further biochemical<br />

tinkering needs to happen in order to extract energy. The<br />

body's preferred source of energy is glucose, but energy<br />

can also be obtained from fat and protein.<br />

After glucose has been gently shoved into the cell by<br />

insulin, the next step - glycolysis - begins the energyreleasing<br />

process. With the help of various enzymes,<br />

glycolysis is a series of chemical conversions that<br />

changes the six-carbon glucose ring into 2 three-carbon<br />

units known as pyruvic acid.


28 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

Little energy is released in this process and sometimes<br />

that is all that is needed, but usually the maximum amount<br />

of energy is required. The pyruvic acid enters the next<br />

stage, known as the Krebs cycle or citric acid cycle, a kind<br />

of biological ferris wheel. At each station of the wheel's<br />

revolution, the molecule will be set upon by certain<br />

enzymes, releasing energy along the way. After all the<br />

energy has been delivered, all that is Iefi is water (H 2 0)<br />

and carbon dioxide (C02) which can be breathed out of<br />

the body. The ferris wheel is located on little organelles<br />

(structures <strong>with</strong>in cells) called the mitochondria. Cells containing<br />

lots of mitochondria, like muscle cells, are able to<br />

produce lots of energy. Cells <strong>with</strong> relatively few rnitochondria,<br />

like fat cells, produce less energy.<br />

The Krebs cycle will only be activated if oxygen is<br />

available. If, for some reason, oxygen is scarce, the<br />

pyruvic acid will be converted to lactic acid. Movement<br />

of the body requires muscle power and muscles need<br />

energy, especially so during exercise. Unless plenty of<br />

oxygen is available to activate the Krebs cycle there will<br />

be a build-up of Iactic acid, which causes an unpleasant<br />

sensation. If a particular group of muscles is worked<br />

powerfdly for more than a few seconds we often experience<br />

a burning sensation.<br />

Incidentally, this is what aerobic exercise is all about.<br />

With sufficient oxygen, muscles are able to use energy<br />

obtained via the Krebs cycle. Aerobic exercise includes<br />

running, swimming and cycling; as opposed to anaerobic<br />

exercise such as weight lifring, where you're more<br />

likely to feel the lactic acid burn.<br />

If the glucose isn't immediately snapped up and used for<br />

energy it can be packed up and stored for a while to be used


Carbohydrates: Fuel and Fibre 29<br />

as energy at another time. One way of doing this is creating<br />

glycogen, the complex carbohydrate mentioned earlier. The<br />

only hiccup here is that there is limited amount of storage<br />

space for glycogen: around half a kilo. So, if all the glycogen<br />

storage space is taken, any extra glucose will be converted to<br />

fat.<br />

Our body performs an act of alchemy changing carbohydrate<br />

into fat. Fat and carbohydrate are completely different<br />

entities, although they both contain the basic units of carbon,<br />

hydrogen and oxygen. Eat is the most economical way to<br />

store extra energy. We store energy as fat because it takes up<br />

less room than storing it as carbohydrate.<br />

Cows can, horses can, even mice can digest<br />

fibre<br />

Fibre is an important part of our diet, yet it is not a nutrient.<br />

It contains no calories, thus can give us no energy and<br />

virtually passes through the digestive system untouched.<br />

Nevertheless, you will be a very sick puppy if you don't eat<br />

enough fibre.<br />

Fibre is a type of carbohydrate found in plants. The human<br />

digestive system does not have the correct enzymes to break<br />

down and absorb fibre. However, cows, horses, even mice<br />

have the enzymes to utilise fibre for fuel.<br />

Types of fibre<br />

Until a few years ago fibre was fibre. It was the husky bran<br />

surrounding wheat called cellulose, the bit that gets stuck in<br />

your teeth. When it first became apparent that fibre had some<br />

benefit, we all raced for the bran and began tipping it into


30 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

and onto everything. What was formerly sneered at as chaff<br />

for horses became the `in ' food for the health conscious. Chaff<br />

suddenly trebled in price <strong>with</strong> the emergence of bran barons!<br />

Nowadays, our knowledge of fibre is a lot more extensive.<br />

For a start, we know that there are several different varieties<br />

apart from cellulose.<br />

Cellulose is the fibre that gives plants backbone. It is insol-<br />

uble in water. Cellulose is found mainly in the bran of grains<br />

such as wheat.<br />

Pectin is abundant in fruits; for example, apples, oranges<br />

and also in some root vegetables. Pectin swells up in size<br />

when it is dissolved in water and for this reason is helpful in<br />

treating constipation and diverticulitis, as it helps form a<br />

bulkier,<br />

softer stool. It is a soluble fibre, capable of lowering cholesterol<br />

and removing toxins from the body.<br />

Mucilage is a type of fibre that is water soluble and forms soft<br />

and demulcent slippery stuff; for example, linseed, psyllium,<br />

slippery elm and marshmallow. These fibres are used to help<br />

soothe irritated linings of the digestive system as in ulcers,<br />

colitis and diverticulitis. It is also very good for constipation<br />

where the stool is hard and difficult to pass.<br />

Algin is a type of fibre found in seaweed. Although it is mostly<br />

used in the food-processing industry, the fibre in seaweed<br />

has the ability to chelate <strong>with</strong> heavy metals such as lead, so it<br />

makes a very good detoxifier. It also reduces the<br />

ill-effects of radiation, which made seaweed very popular<br />

post-Chernobyl.<br />

Resistant starch is starch which resists digestion and<br />

passes<br />

through to the large bowl. Beans contain some of this resistant<br />

starch, which is known as oligosaccharides.<br />

Chitin is an unusual fibre, one that is not carbohydrate, found<br />

in fungi, yeasts and the exoskeleton of invertebrates such as<br />

insects and crustaceans. It is basically insoluble and has been<br />

found to absorb fats. The diet industry has cottoned on to


Carbohydrates: Fuel and Fibre 31<br />

this and has produced tablets containing chiton that will stop<br />

fat from being absorbed. This is not a good way to lose weight<br />

as fat brings to us so many important compounds, including<br />

the fat soluble vitamins.<br />

Lignin is another non-carbohydrate fibre. It is found in the<br />

woody parts of plants like the stems and cores of apples and<br />

pears, as well as in linseeds, rye and buckwheat. Lignin can<br />

be metabolised by gut microflora into lignan, a phyto-oestrogen,<br />

offering protection against hormone-dependant cancers<br />

such as breast, uterine and ovarian cancer.<br />

Dietary recommendations<br />

Eat 30 to 40 grams of fibre daily. This looks like: three to<br />

five vegetable servings, plus two to four fruit servings, plus<br />

six to eleven wholegrain pasta or bread or legume servings.<br />

It is best to increase your fibre intake gradually over several<br />

weeks to allow the digestive system to adapt. Otherwise you<br />

(and your loved ones) will experience flatulence.<br />

Drink lots of water, fibre is very thirsty. If you don't drink<br />

enough water, you will find your stools become dry and hard.<br />

Select a variety of fibres from a variety of foods; for example,<br />

fruits (including skin, pits and cores), seeds, vegetables (root<br />

and leafy), grains and legumes.<br />

What fibre can do for you<br />

In the bowel<br />

Fibre generally accelerates transit time, meaning that it takes<br />

less time for food to travel the length of the digestive tract<br />

from mouth to anus. In general, this is seen as a good thing.<br />

In the Western world, transit time is far too slow, adding to


32 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

all sorts of problems including constipation and bowel cancer.<br />

The longer the stool is present in the bowel, the longer it has<br />

time to form toxic products of fermentation and putrefactions.<br />

Some of these will be absorbed into the bloodstream. Fibre<br />

is as good for constipation as it is for diarrhoea. This may<br />

sound contradictory but the soluble fibres, including pectin<br />

and psyllium, swell up so much that they can slow down a<br />

too-speedy transit time, allowing time for nutrients to be<br />

absorbed, one of the problems <strong>with</strong> diarrhoea.<br />

Heavy metal<br />

Fibre has the ability to hold on to and excrete heavy metals<br />

such as lead, aluminium and mercury. The less of these in<br />

the body, the better. The down side is that fibre can also<br />

hold on to good minerals such as calcium and iron. This is<br />

one reason not to add extra bran to the diet but rather to eat<br />

a diet that is intrinsically rich in fibre; foods that will provide<br />

extra minerals instead of just removing them.<br />

Phytates<br />

Phytates are not a kind of fibre, although they are oAen<br />

found in cereals and legumes. Phytates or phytic acid<br />

can reduce the absorption of certain minerals, including<br />

iron, zinc, calcium and others. Phytic acid is the calcium<br />

or magnesium salt of inositol and phosphoric acid. Phytates<br />

are destroyed by heat which means that baked or<br />

cooked grains and legumes do not contain significant<br />

amounts of phytates, although consuming large quantities<br />

of raw bran and uncooked rolled oats could be a<br />

problem.


Ca~bohyd~ates: Fael and Fibre 33<br />

Decrease choIestero1<br />

Fibre, particularly soluble fibre, decreases cholesterol. One of<br />

the mechanisms is that it will hold on to excess cholesterol<br />

in the bowel and prevent it from being reabsorbed.<br />

Help <strong>with</strong> weight loss<br />

Fibre slows the rate at which food leaves the stomach. This<br />

has a twofold benefit. First, you will feel fuller longer after<br />

you have eaten, helping you to lose weight. Second, as nutrients<br />

take longer to be absorbed, blood sugar levels rise<br />

slower, which is very good if you suffer from diabetes or<br />

hypoglycaemia.<br />

Prebf 0th<br />

Because fibre is not absorbed in the small intestine, the bacteria<br />

in the lower bowel are able to use it for fuel. Fibre is<br />

the 'prebiotic' that feeds the good bugs, known as probiotics<br />

(see box on page 34). The bacteria nibble on the fibre and<br />

in return give us some valuable by-products, including antibiotic<br />

substances (for example, nisin), which help fight bowel<br />

infections. In addition, the bacteria produce short-chain fatty<br />

acids (SCFAs), mainly acetate, propionate and butyrate in the<br />

ratio 60:24:16 (see box on page 47). These short-chain fatty<br />

acids have shown to be incredibly beneficial. They are used<br />

as fuel by the cells that line the bowel and are probably the<br />

reason behind the statistic that people whose diets are low in<br />

fibre are more likely to get bowel cancer. A couple of less<br />

popular by-products include the gases hydrogen, carbon<br />

dioxide and methane - the main components of flatus.<br />

Increased fibre has proved to be helpful as part of a treatment<br />

and preventative regime for the following conditions:<br />

diverticulitis, constipation, colon cancer, heart disease,<br />

obesity, gall stones, varicose veins and irritable bowel<br />

syndrome.

Probf otfcs<br />

It is ironic that while spending countless dollars and<br />

hours ridding ourselves and our homes of germs, there<br />

resides literally biions of the blighters <strong>with</strong>in our<br />

bodies. There are more bugs in the bowel than there<br />

are cells in the body. Such bugs are,collectively known<br />

as bowel microflora and the beneficial ones are called<br />

Some of the more famous beneficial microbes include<br />

Lactobacillus acidophilus (acidophilus) found in the<br />

bulgaricus, Lactobacillus brevis and Streptococcus<br />

they do good deeds then go.<br />

Certain strains of microflora are capable of producing<br />

the B vitamins biotin, niacin (B3), pyridoxine (B6), folic<br />

acid (B9), as well as vitamin K. Others act as watchdogs<br />

of the internal environment, secreting substances which<br />

promote the growth of beneficial microorganisms and<br />

substances toxic to pathogenic bacteria and viruses.<br />

Others produce lactase, an enzyme that helps digestion<br />

of milk sugar. Conditions including acne, constipation,<br />

psoriasis, bloating, flatulence, even tumours can<br />

respond positively to the substances created by these<br />

microorganisms.<br />

Tipping the balance<br />

Convinced yet these guys are paying their way? Microflora<br />

irritable bowel syndrome, diarrhoea, abdominal X-rays,<br />

radiotherapy, a serious infection, a sudden change in<br />

diet, stress, the contraceptive pill, drinking tap water<br />

containing chlorine (chlorine is antimicrobial), steroids<br />

such as cortisone and taking antibiotics. Antibiotics are<br />

designed to kill bacteria - killing the good along <strong>with</strong> the<br />

bad. After a course of antibiotics, or if any of the above<br />

situations apply, then it is wise to go on a short program<br />

of friendly bacteria, such as acidophilus and bifidus. This<br />

will help reinstate healthy microflora.

Protein:<br />

Strength and Structure<br />

Look in the mirror - what you see is protein<br />

Protein comes from the ancient Greek word protos, meaning<br />

first. Long thought to be the most important or primary nutrient,<br />

nowadays we acknowledge protein's significance but also<br />

recognise the equal importance of carbohydrates and fat.<br />

Protein provides our physical structure. Pretty much all that<br />

you see in the mirror - hair, skin, nails, as well as muscle and<br />

even bone - is predominantly protein. Just as protein creates<br />

most of our macrostructure, so too is it vital for microstructures;<br />

the miniature nuts and bolts that keep us ticking over. All<br />

enzymes, neurotransmitters, blood proteins such as haemoglobin,<br />

antibodies and many hormones are made out of protein.<br />

No other nutrient will do; if there is no protein these macroand<br />

microstructures cannot be built. People whose diets are<br />

low in protein often suffer symptoms ranging from brittle hair<br />

and nails, poor immune function and delayed healing to muscle<br />

weakness. More severe protein deficiency eventually leads to<br />

to blindness, oedema, muscle wasting and death.

Kwashiorkor<br />

Kwashiorkor is the name given to severe protein deficiency.<br />

African in origin, kwashiorkor literally means<br />

'disease of the first born when the second baby is put<br />

on the breast': a terribly sad reality where the only<br />

protein available is through the mother's milk. An ironic<br />

symptom of kwashiorkor is a swollen belly. This is<br />

because the blood protein albumin retains water <strong>with</strong>in<br />

blood vessels. Without enough protein there is insufficient<br />

albumin and so water leaks from the blood vessels<br />

and swells the abdomen.<br />

Protein can also provide us <strong>with</strong> calories for energy - 4 calories<br />

a gram (the same as carbohydrate). However, as neither<br />

carbohydrate nor fat provide us <strong>with</strong> the structural building<br />

blocks that protein supplies, using protein for energy is a tad<br />

wasteful.<br />

How much is enough?<br />

Unlike fat, protein cannot be stored in the body and so it is<br />

imperative that we eat enough protein each day to rebuild<br />

and repair muscles, enzymes, fingernails and eyelashes. If the<br />

body does not receive adequate protein from the diet every<br />

day, it will procure it somehow, usually by breaking down<br />

muscle tissue. So it is of no use to go on a protein binge one<br />

day a week, hoping that on average your protein intake is<br />

sufficient. The generally accepted recommendation for daily<br />

protein to keep us out of trouble is 1 gram per body kilogram.<br />

For instance, a 60 kilogram person requires 60 grams of<br />

protein a day. Roughly the same weight as a good-sized egg


Protein: Strength and Structure 39<br />

(although a 60 gram egg contains only 8 grams of protein, the<br />

rest being carbohydrate, fat and water).<br />

Who needs extra?<br />

During pregnancy an extra 6 grams of protein is required<br />

daily to meet the structural needs of the growing baby.<br />

Breastfeeding a baby requires that you eat an extra 12 to 16<br />

grams of protein daily. Children need proportionately double<br />

the protein an adult needs, due to the need to increase body<br />

structure. A growing child needs up to 2 grams per body<br />

kilogram. So a 30 kilogram child would need as much protein<br />

as a 60 kilogram adult; that is, 60 grams.<br />

Some body builders keen to be chiselled, cut and sculpted<br />

eat protein by the bucketload (12 egg whites for breakfast),<br />

although our body's capacity to build muscle is limited to our<br />

genetic potential. Excess protein will be used as calories or<br />

stored as fat and may eventually lead to problems <strong>with</strong> the<br />

liver and kidneys.<br />

The problem <strong>with</strong> excess protein<br />

Protein, unlike carbohydrate and fat, contains nitrogen.<br />

We lose about 30 grams of nitrogen in the general<br />

house-cleaning and maintenance that goes on in the<br />

body every day. The liver converts the nitrogen into<br />

ammonia and then urea, which the kidneys excrete via<br />

the urine. Normally, the body copes <strong>with</strong> this amount<br />

of waste nitrogen. The trouble starts when excess<br />

protein (more than double our requirements) is consumed<br />

(remember, we cannot store excess protein).<br />

The ammonia and urea are toxic and can cause<br />

damage, especially to the kidneys.

Amino acids: the Lego blocks of life<br />

Protein is made up of lots of little units called amino acids.<br />

There are about 100 amino acids in nature and over 20 in the<br />

human body (see box below). Just like Lego blocks, amino<br />

acids can join together into all sorts of shapes but most often<br />

form chains, joined together by peptide bonds. These chains<br />

can grow quite long, up to hundreds of amino acids in a row,<br />

and the chains can cross and link <strong>with</strong> one another to form<br />

complex structures.<br />

Although an eyelash looks quite different from a toenail<br />

(one hopes), nearly all body structures are made up of protein.<br />

They look different because they contain different variations<br />

of the 20 amino acids, making an infinite number of combinations.<br />

It is the type of amino acids and their combination<br />

in the polypeptide chain, that determine the function and<br />

look of a particular protein.<br />

EM: all or nothing at all<br />

Our body needs all 20 amino acids to make the different<br />

proteins essential for life. When necessary, the body can<br />

create a new amino acid out of an old one. A bit of a cut and<br />

paste job: tack on a few carbons here, take away a few<br />

hydrogens there. Pretty clever stuff. However, there are a few<br />

amino acids that cannot be created from others. Known as the<br />

essential amino acids (EAAs), these amino acids must be<br />

eaten daily. As mentioned previously, we need 1 gram of<br />

protein per body kilogram, and that protein must be of good<br />

quality. Good quality doesn't necessarily mean it comes from<br />

David Jones, but food that delivers all the essential amino<br />

acids.

For many years non meat-eaters were depicted as pasty

and anaemic <strong>with</strong> a predilection towards communist philosophies.<br />

However, it soon became apparent that vegetarians<br />

were a defiantly healthy mob. Studies on Seventh Day<br />

Adventists show they suffer less obesity, heart disease,<br />

cancer, diabetes and virtually every other modern-day illness.<br />

And they live longer to enjoy it. The vegetarian diet generally<br />

is higher in fibre and lower in fat.<br />

Formerly, it was believed that all the essential amino acids<br />

needed to be eaten at the same meal. Now we know there<br />

is some leeway. If you eat a food low in one of the amino<br />

acids for breakfast, as long as you eat a food that contains a<br />

reasonable amount of this amino acid sometime in the next<br />

12 hours or so all will be well.<br />

Recipe for success and toenails: the art of<br />

protein synthesis<br />

How the body knows which protein to make, and when,<br />

is coded in genes on strands of DNA located in the<br />

nucleus of nearly all cells. There is information (recipes)<br />

on every aspect of us in these wispy threads of genetic<br />

material. When we need to grow a toenail, the recipe<br />

we need will be located at a particular point on the DNA<br />

strand - called a gene. If a toenail is required, only that<br />

recipe will be accessed, however tempting that vanilla<br />

soume recipe is on the next gene.<br />

First a copy of the recipe is made (messenger RNA) in<br />

the nucleus and is taken downstairs to the kitchen (cytoplasm).<br />

The recipe is very specific as to which amino acids<br />

go where, causing them to line up in a specific sequence<br />

to form our peptide chain (for example, Ser-Ser-Gly-Leu-<br />

Asn-Met-Met-Gln-Pro-Trp and so on). As each consecutive<br />

amino acid is needed for the recipe, a call goes out<br />

on the public announcement system for that amino


Protein: StrengfA and Stmctzcn 43<br />

acid - for example, serine (a non-essential amino acid) -<br />

to come forth. If there happens to be a serine in the near<br />

vicinity, it will step into line. If no serine is around, a suitable<br />

candidate wiII front up and sacrifice itself to a total<br />

makeover, becoming transformed into serine. In the event<br />

that an essential amino acid like tryptophan is needed,<br />

the call will go out on the PA system as before. If no<br />

tryptophan turns up, another more desperate call will be<br />

made. If still no tryptophan appears, we are in big<br />

trouble - the aforementioned toenail cannot be made.<br />

This may sound like good news (no more nail clippings<br />

on the carpet), however, if there is no tryptophan for toenails<br />

there will be no tryptophan for skin, muscle and<br />

enzymes. We need to have the essential amino acids on<br />

hand 24 hours a day or all protein making goes on strike.<br />

This is why it is crucial to our well-being to ensure that<br />

every day we eat enough protein containing all the essential<br />

amino acids.<br />

Are you getting enough?<br />

When I analyse people's diets, one of the most frequent deficiencies<br />

is protein. A good example is Michelle. Aged 28,<br />

Michelle has a busy life: a successful job in marketing, good<br />

friends and a membership to the gym which she visits daily<br />

because she thinks she has fat thighs. (She doesn't.) Michelle's<br />

main reason for seeing me was her lack of energy. When<br />

questioned, her energy levels had been low for a few years,<br />

and steadily getting worse. I always ask for people to measure<br />

their energy levels according to a scale of 0 to10 <strong>with</strong> 10 being<br />

'jumping full of beans'. Michelle was a very weary 4 to 5<br />

on the energy scale. Within two weeks of eating a diet that


44 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

contained more protein, Michelle's energy levels had lifted<br />

to 8 or 9. It is often this simple.<br />

Part of the problem was that Michelle simply did not know<br />

what foods contain protein. When I suggested that protein<br />

may be the answer, she agreed to try this novel approach but<br />

was worried about putting on weight. (Those thighs again.)<br />

So I gave her a list of protein foods that were relatively low<br />

in fat and asked Michelle to have one serve <strong>with</strong> each meal.<br />

The list of high proteinllow fat foods was tuna in brine,<br />

sardines in brine, egg, low-fat humus, low-fat ricotta, cottage<br />

cheese, lean red meat, chicken <strong>with</strong>out the skin, 10 almonds,<br />

kidney beans, tofu, low fat yoghurt.<br />

Clever vegetarianism: protein combining<br />

Animal-made protein more closely reflects the human requirements<br />

of essential amino acids, <strong>with</strong> eggs carrying the<br />

prize for the most 'complete' protein. (Remember, the total<br />

amount of protein in the average egg is 8 grams, which would<br />

mean you would need to eat eight eggs a day if you were<br />

only getting protein from this source.)<br />

Generally if you are happy to eat some animal products -<br />

for example, cheese, yoghurt, eggs, fish, chicken, beef, lamb<br />

and so on - you don't need to be too conscious of worrying<br />

about the essential amino acids.<br />

Nearly 30 years on, the landmark book Diet for a SmaN<br />

Planet by France Moore Lappe (first published in 1971) is<br />

still the best book on the subject of protein in vegetarian<br />

food. Lappe was a card-carrying member of the flower-power<br />

generation who were vegetarian for various political and<br />

ethical reasons. Fed up <strong>with</strong> people saying she would die of<br />

protein deficiency if she didn't eat meat, Lappe did her<br />

homework and found that by combining certain plant foods


Protein: StrengtA and Stmctu~e 45<br />

you would obtain all the necessary essential amino acids.<br />

Beans, grains, nuts and seeds have the most essential<br />

amino acids, while fruits and vegetables (except sprouts) tend<br />

to be a write-off when it comes to protein. Plant proteins, not<br />

surprisingly, don't reflect the human range of amino acids,<br />

although soybeans come surprisingly close. Beans lack the<br />

essential amino acids that grains have in spades and vice<br />

versa.<br />

Lappe drew parallels <strong>with</strong> the world's major cuisines,<br />

which happen to be predominantly vegetarian, noticing that<br />

for centuries people have been combining plant foods so as<br />

to take full advantage of complementary amino acids. For<br />

example, the South Indian dish of dhal and rice combines<br />

lentils, a legume, <strong>with</strong> rice, a grain. The Asian meal of tofu<br />

and rice combines tofu made from soybeans, a legume, <strong>with</strong><br />

rice, a grain. (Soybeans have the highest protein of any<br />

legume.) Central Americans combine red or kidney beans, a<br />

legume, <strong>with</strong> tortillas made from corn, a grain. In Lebanon,<br />

the felafel roll combines felafel made from chickpeas, a bean,<br />

<strong>with</strong> flat bread made from wheat, a grain. You can add substantially<br />

to protein levels by throwing in a few toasted sunflower<br />

seeds, sprouts or sesame seeds, which will add a few<br />

more essential amino acids. Of course if you add a small<br />

amount of animal protein to your vegetarian meal, including<br />

some grated cheese, a dollop of natural yoghurt or even a<br />

small amount of meat, you will have no worries about getting<br />

sufficient protein.


Fat: Not a Dirty Word<br />

Fat the Rat<br />

It is amazing how three little letters F, A and T can send<br />

people into paroxysms of fear and loathing. After all, it is just<br />

a nutrient and a rather valuable one at that. No other nutrient<br />

gives us the fat soluble vitamins A, D, E and K; or sterols<br />

such as cholesterol, oestrogen, testosterone, aldosterone and<br />

cortisol; let alone the phospholipids that line the outside of<br />

nerves and create part of each cell membrane; or the<br />

prostaglandins - chappies that have a profound impact on our<br />

health. One can expect only so much from carbohydrates and<br />

protein: only fat delivers these beauties.<br />

The official name for fat is 'lipid', which refers to the more<br />

solid fat as well as its liquid counterpart, oil.<br />

Getting to know you<br />

Ninety-nine per cent of fat in the body and in food is in the<br />

chains of fatty acids joined together at one end. A fatty acid<br />

(the basic unit of fat) is a chain of carbons extending in length<br />

anywhere from 2 to 22 carbons long. There are short-, mediumand<br />

When scientists classify fatty acids, they don't just call<br />

them Bobby-joe or Charlie. They name them according<br />

to the number of carbons, how many double bonds and<br />

where the first double bond is positioned. For example,<br />

EPA is 20:5w3. This means it has 20 carbons, five<br />

double bonds <strong>with</strong> the first double bond occurring on<br />

the third carbon from the end, which also makes it an<br />

Saturated and unsaturated fatty acids<br />

The fatty acid chain looks like a daisy chain. The daisy flower<br />

being the carbon, while the stalk represents the bond. Sometimes<br />

there are two bonds (double bond) joining the carbon


Fat: Not a Dirty Word 49<br />

atoms together. A double bond is not as stable as a single<br />

bond; there is a likelihood that one of the bonds will reach<br />

out and grab something else - for instance, oxygen. If there<br />

are no double bonds, the fatty acid is called a saturated fatty<br />

acid. Like a sponge fully saturated <strong>with</strong> water, there is no<br />

opportunity for those bonds to hold on to anything else. If<br />

there are any double bonds it is known as an unsaturated fatty<br />

acid. Two or more double bonds make it a polyunsaturated<br />

fatty acid ('poly' meaning many).<br />

Nattering on about the structure of carbon chains and<br />

double bonds is all very well if you happen to be looking<br />

down an electron microscope, however, there is an easier way<br />

to identify saturated from unsaturated fats just by looking at<br />

them. The more unsaturated a fat - that is, the greater the<br />

number of double bonds - the more liquid it appears. This<br />

means that the more solid fats such as butter and lard contain<br />

more saturated fatty acids; whereas the runnier oils like<br />

safflower and sunflower have three and four double bonds<br />

apiece. Then you have your 'in-between' oils such as olive<br />

oil, which is liquid until put in the fridge where it gets claggy.<br />

This is because olive oil (and canola oil) contains monounsaturated<br />

fatty acids, which means there is only one double<br />

bond (mono): not as liquid as polyunsaturated and not as hard<br />

as saturated fats. I am sure there is a more scientific way to<br />

explain this, but there you go.<br />

Fats and oils are made up of several types of fatty acids,<br />

not just one. The different fatty acids will determine how<br />

saturated or unsaturated a fat is. For instance, butter is predominantly<br />

saturated and contains a lot of the saturated fatty<br />

acid butyric acid. Nevertheless, butter will also contain a few<br />

unsaturated fatty acids as well.

Better to be a peroxide blonde than a peroxide<br />

polyunsaturate<br />

Polyunsaturated fatty acids (those <strong>with</strong> two or more double<br />

bonds to their name) have a very fragile chemical structure.<br />

Anything that interferes <strong>with</strong> that double bond, including<br />

heat, light and other chemicals, can cause that fatty acid to<br />

become peroxidated - that is, an oxygen molecule is incorporated<br />

into the structure. This is bad, bad news. This lipid<br />

peroxide is capable of causing free radical damage to its<br />

immediate surroundings, be it a cell membrane or anything<br />

else. This process is considered to be a trigger in many diseases<br />

including cancer and atherosclerosis. The dodgy lipid,<br />

once incorporated into the body, then wreaks havoc unless<br />

there are suitable defenders available, namely the antioxidants.<br />

Vitamin E is a lipid-soluble antioxidant and should<br />

be liberally scattered through all our cell membranes.<br />

Fat and fabulous<br />

Fat is the nutritional equivalent of Louis Vuitton luggage:<br />

you can fit so much in! Each gram of fat supplies us <strong>with</strong><br />

nine calories of energy, whereas carbohydrate and protein<br />

give us four calories a piece. This means, for weight and size,<br />

fat is a very economical form of storage. Mountain climbers<br />

and trekkers who want to travel light carry food high in fat,<br />

like chocolate and halvah, to provide them <strong>with</strong> more energy<br />

gram for gram. If our bodies were to store the equivalent<br />

amount of energy in the form of carbohydrate, instead of fat,<br />

we would be the size of a big tree. In fact, trees and other<br />

plants do happen to store their energy as carbohydrate.<br />

Wherever there is a double bond, the chain of carbons<br />

like the letter 'C'. This transfiguration is called 'cis'. Occasionally<br />

another formation occurs, where the chain continues<br />

on the opposite side of the double bond - this is<br />

called a trans fatty acid. Although rare in nature, trans<br />

fatty acids occur frequently during the processing of fats<br />

for cooking oil and margarines. Recent information has<br />

revealed that these trans fatty acids are bad for our<br />

health.<br />

again. My darling father used to tell me it was a good thing<br />

to carry a little padding to fall back on if you got sick. Speaking<br />

of falling back on, fat makes a wonderful insulation layer<br />

between the outside world and you. Which is why women<br />

have an extra layer covering the womb (mind you, this does<br />

not explain the extra layer covering the thighs). In these days<br />

of paranoia about being thin as a stick, we forget the value<br />

of a little extra padding. Thanks Dad.

oil to drizzle over the barbecued bronto-rib.<br />

Because fat is susceptible to light and heat, nature has<br />

evolved some ingenious solutions. For example, nuts are a highfat<br />

food and they always have a hard covering that protects the<br />

fat from light. The high-fat macadamia has the hardest shell<br />

of all. The avocado is one of the few fruits that store energy<br />

in the form of fat; it has a dark, leathery skin that protects the<br />

fatty acids from oxidation. Until relatively recently we did not<br />

have the technology to obtain fat from food. The earliest<br />

attempts would have been stone-pressed olive oil and, in cooler<br />

climates, butter from churning cream. Both these fats are at<br />

less risk of becoming oxidised because they are monounsaturated<br />

and saturated respectively (fewer double bonds to worry<br />

about). Historically, fat has been a luxury food, available only


Fat: Not a Dirty Word 53<br />

to the wealthy until modern-day improved food technology.<br />

Today, oil is cheap and readily available on supermarket<br />

shelves in clear plastic bottles, baring all their little unprotected<br />

double bonds to the ubiquitous fluorescent lights.<br />

EPO and UFOs: the story of essential fatty<br />

acids<br />

I was fine <strong>with</strong> the UK. Even the USA posed no threat. Then<br />

there was UNICEF, ANZUS and eventually KFC. I could<br />

cope. But it was only when the world of initials (or acronyms)<br />

struck oil that I realised that the New Age had finally gone<br />

Space Age.<br />

More than any other field of nutrition, research into lipids<br />

(fats or oils) has flourished in recent years. Many people are<br />

aware of the benefits of EPO and EPA. Some know the<br />

importance of a high percentage of GLA. Yet, how many of<br />

us understand what the heck these initials stand for? And<br />

what exactly is so good about them?<br />

Fatty acids are the building blocks of fats. There are many<br />

different fatty acids - for example, oleic acid (OA) found in<br />

olive oil and butyric acid (BA) found in butter. Linoleic acid<br />

(LA) and alpha-linolenic acid (LNA) are known as the essential<br />

fatty acids (EFAs), because of the fact that we cannot do<br />

<strong>with</strong>out them. They are essential to health. I guess that must<br />

make them VIP EFAs! It is these EFAs and their derivatives<br />

that have spectacular health benefits.<br />

Prostaglandins<br />

In the body, EFAs can be transformed into biologically active<br />

substances known as prostaglandins. The study of prostaglandins<br />

(PGs, wouldn't you know) is very new and very exciting.


54 The Commonsense Ggide to <strong>Eating</strong> Weld<br />

The prostaglandins derived from LA and LNA, our EFAs,<br />

keep blood platelets from sticking together, preventing heart<br />

attacks and strokes. They also prevent fluid retention and<br />

decrease the inflammation response, thereby helping <strong>with</strong><br />

menstrual cramps, eczema and arthritis. In addition, they<br />

improve the functioning of our immune system's T-cells, so<br />

important in the fight against infection. Regulating hormones<br />

is another key area, helpful for PMS, menopause, hormonal<br />

headaches and acne.<br />

We are able to make these valuable prostaglandins from<br />

EFAs (LA and LNA) in food. However, the average diet is<br />

sadly lacking in good quality EFAs derived from seeds, whole<br />

grains, leafy green vegetables, cold-pressed oils and fish.<br />

In addition, although our bodies are capable of producing the<br />

prostaglandins from the EFAs, many people have trouble <strong>with</strong><br />

the first step. As in most biochemical processes, each step<br />

requires an enzyme. Enzymes are sensitive little characters,<br />

often requiring the support of vitamins and minerals - in this<br />

case, vitamin B6, zinc, magnesium and vitamin C - some of<br />

which are deficient in the modern diet. Factors that inhibit this<br />

enzyme include processed fats such as margarine, alcohol, radiation,<br />

aspirin, stress and a high-sugar diet.<br />

Mysterious substance X<br />

The answer is simple. By eliminating the first step and taking<br />

the substance that would normally be produced if our enzyme<br />

was firing on all cylinders, we will conveniently by-pass the<br />

problem. Let's call this substance 'substance X'. Substance<br />

X has no difficulty in transforming into prostaglandins.<br />

Just who or what is substance X? None other than gammalinolenic<br />

acid (GLA), found in evening primrose oil and


Fat: Not a D iq Word 55<br />

eicosapentaenoic acid (EPA) commonly found in fish and linseeds:<br />

GLA and EPA are the substances produced after the<br />

first step. Many people find that supplementing their diet<br />

<strong>with</strong> evening primrose oil (containing GLA) and EPA provides<br />

the key to good health. They help to treat and prevent<br />

conditions such as eczema, acne, headaches, PMS, hormonal<br />

irregularities, cancer, heart disease and so on. A combination<br />

of the two is thought to be preferable to one in isolation. Of<br />

course we should increase our consumption of EFA-rich<br />

foods - including linseeds, sunflower and sesame seeds, soy,<br />

walnuts, dark green leafy vegies, fish and whole grains - in<br />

addition to helping that errant enzyme by taking foods or<br />

supplements <strong>with</strong> the appropriate co-enzyme.<br />

Good cholesterol and LPs: the tmth about<br />

what happened to those 12-inch vinyls<br />

Fat and water don't mix. Fat tends to glob together in a<br />

blob when it is immersed in water. Blood is 99 per cent<br />

water and the major transport system of the body, so a<br />

solution had to be found to this fatlwater incompatabiiity.<br />

LPs are the answer. Not the 12 inch vinyl variety,<br />

these LPs (lipoproteins) are fat transport vehicles. Lined<br />

<strong>with</strong> a coating of protein, which is water soluble, lipoproteins<br />

contain a variety of fatty substances including<br />

triglycerides, cholesterol, phospholipids, hormones and<br />

fat-soluble vitamins.<br />

It depends on the proportions of its cargo whether a<br />

lipoprotein is high or low density. As protein has more<br />

density than fat, the less fat a lipoprotein contains, the<br />

higher its density.


56 The Commonsense Gzcide to <strong>Eating</strong> <strong>Well</strong><br />

CHnOMICRON This is the lowest density lipoprotein<br />

of all. It is diet-derived LP that travels<br />

from the intestine to the liver aAer<br />

digestion. Chylornicrons ferry fat to<br />

the tissues before its arrival in the liver.<br />

VLDL Very Low Density Lipoprotein. This<br />

contains mostly triglycerides and will<br />

be converted to LDL.<br />

LDL<br />

Low Density Lipoprotein. LDLs contain<br />

the most cholesterol of all the low<br />

density group. They are responsible<br />

for distributing choIestero1 and other<br />

fats throughout the body.<br />

HDL High Density Lipoprotein. This contains<br />

the most protein and hence, has<br />

the highest density of all the LPs. It is<br />

capable of returning cholesterol from<br />

the blood vessels to the liver. The liver<br />

will then produce bile acids from any<br />

excess choIesteroI.<br />

The greater the ratio of HDLs to LDLs the better. When<br />

we get our cholesterol 'done', a reading of total cholesterol<br />

is given. This is the choIesteroI found in all the LPs.<br />

If this is high, then a further reading will be necessary<br />

to determine whether the cholesterol is 'good' or 'bad'.<br />

The cholestero1 itself doesn't change, it is whether the<br />

ratio of HDLs is high relative to the LDLs.<br />

Cholesterol: nightmare or blessing?<br />

Cholesterol is the Jack Nicholson of the nutrition world. Constantly<br />

being given the role of the bad, crazy guy. I can't


Fat: Not a Dim Word 57<br />

vouch for Jack, but cholesterol has some very positive traits.<br />

It is the precursor of bile (the fat-digesting secretion of the<br />

liver), oestrogen, progesterone, testosterone, cortisol and<br />

vitamin D. Cholesterol is an integral component of every cell<br />

membrane and forms part of the myelin sheath around nerve<br />

fibres. The alarm was initially raised when cholesterol was<br />

found in artery blockages. However, cholesterol in the arteries<br />

is just a sign, not the cause. Blaming cholesterol for heart<br />

disease is like shooting the messenger.<br />

Cholesterol occurs in animal foods such as chicken, eggs,<br />

lamb, beef, milk, cheese and pork. It is a type of fat manufactured<br />

in the liver. We make our own cholesterol, as well as<br />

consuming cholesterol from the food we eat. You will not find<br />

cholesterol in plant foods, even those containing fat such as<br />

avocados and coconuts, as they do not have livers. The amount<br />

of blood cholesterol usually stays constant: the liver makes less<br />

if we consume more and vice versa.<br />

'High' cholesterol means higher than normal levels of cholesterol<br />

in the bloodstream. High cholesterol is a risk factor for<br />

atherosclerosis, a common heart disease. More important than<br />

cholesterol levels is the ratio between the high density lipoproteins<br />

(HDLs) and low density lipoproteins (LDLs): the<br />

higher the ratio of HDLs to LDLs, the lower the risk of heart<br />

disease. As mentioned previously, LDL's job is to deposit fats,<br />

including cholesterol, throughout the body and on the insides<br />

of blood vessel walls. HDLs, on the other hand, are capable of<br />

mopping up excess cholesterol from blood vessel walls and<br />

taking it back to the liver to be made into bile or one of the<br />

other useful products that can be made from cholesterol.<br />

A healthy diet and lifestyle will help you maintain an enviable<br />

blood fat profile; that is, lowish levels of triglycerides,<br />

moderate cholesterol, <strong>with</strong> a good HDLILDL ratio (see the<br />

tailor-made diet for a healthy heart on page 219).


58 The Commonsense Gaide to <strong>Eating</strong> <strong>Well</strong><br />

Some slick answers to an oily problem<br />

Fat is important to keep us healthy, our fur shiny and our<br />

noses dry, although too much fat is a problem, as is the wrong<br />

type of fat.<br />

Enter Nathan Pritikin. During the 1970s, Pritikin was the<br />

first to popularise the low-fat diet and lifestyle that proved<br />

to be so effective in reducing heart disease, one of the biggest<br />

killers in the Western world. Since then, however, it seems<br />

that there is more to the story than just the quantity of fat<br />

consumed. Take the Mediterranean diet, which is liberally<br />

laced <strong>with</strong> olive oil, yet friendly for the heart. The Innuit or<br />

Eskimos' traditional cuisine of whale blubber and fish is also<br />

protective against heart disease. Now we know that it is not<br />

just how much fat, but the type of fat that affects our health.<br />

And not only heart disease. The type of fat we consume<br />

influences the outcome of conditions as diverse as arthritis,<br />

eczema, PMS and cancer.<br />

The primary rule is don't add fat. If you have the choice<br />

to add mayonnaise, sauces, dressing, cream, butter or<br />

margarine - don't do it. Other principles to follow are: buy<br />

only cold-pressed oils; if you want to spread something on<br />

your bread, choose a thin scrape of avocado, tahini, ricotta or<br />

hommos; never buy or eat margarine if you can avoid it; read<br />

labels to identify how much fat and what kind it is; and steer<br />

clear of deep-fried anything, particularly cats.<br />

Fat should comprise no more than 30 per cent of our diet.<br />

For the average person, this works out to be about 65 grams.<br />

It is a worthwhile exercise to buy a small 'fat counter' book<br />

and tote up the number of grams of fat you eat each day. You<br />

might be surprised where fat hides. Don't become obsessed<br />

<strong>with</strong> the fat counter. Use it for information, not to beat yourself<br />

up <strong>with</strong>.


Water: The Most<br />

Important Nutrient<br />

Water is the most important nutrient of all. We can live<br />

<strong>with</strong>out food for weeks if need be, but if deprived of water<br />

for more than a day or so, we will surely die. Water is often<br />

the only remedy required for conditions as varied as constipation,<br />

headaches, dry skin and fatigue.<br />

We excrete about 2 to 3 litres of water daily: 1.5 litres via<br />

the urine, 1 litre via sweat and breath and around 100 millilitres<br />

in poo. Water comprises 60 to 70 per cent of our body<br />

weight. It is in the blood, in between and inside cells. Even<br />

bones are 25 per cent water, teeth 10 per cent. We need to<br />

restore what is lost. In addition to the water in food, try to<br />

drink an extra 1 to 2 litres of pure water each day.<br />

It's wet, what else?<br />

Apart from keeping us alive, water has several less obvious<br />

roles in the body:


60 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

In the same way as the ocean moderates coastal temperatures<br />

because it takes longer for water to cool and heat than<br />

does land, our body's water helps us to regulate body<br />

temperature.<br />

Nutrients and waste products, hormones and neurotransmitters<br />

all need to be transported around the body. The<br />

body's transport system - blood, lymph and the fluid<br />

between cells (interstitial fluid) - are primarily made up of<br />

water.<br />

We need tears not only to express our sorrow, but to allow<br />

our eyelids to open and close smoothly. Saliva moistens<br />

food so that it doesn't scrape down the throat. Synovial<br />

fluid between joints stops bones from grating together.<br />

Tears, saliva and synovial fluid are predominantly water.<br />

Water is a marvellous solvent - the medium in which most<br />

nutrients and body chemicals can dissolve.<br />

How do we know when we are thirsty?<br />

This may sound like a silly question. However, by the time<br />

we feel thirsty, our body is already slightly dehydrated. Thirst<br />

occurs when receptors in the hypothalamus in the brain are<br />

stimulated in response to certain changes in the body. These<br />

changes include the following:<br />

Reduction in volume of body fluids by 1 per cent - this is<br />

only about 500 millilitres of water. In a heavy exercise<br />

session it is easy to lose 1 litre (about a cup and a half) of<br />

water and you are too busy (waiting for the class to end)<br />

to notice. This is why it is important to drink water before,<br />

during and after exercise.<br />

An increase in the concentration of dissolved substances in<br />

the blood, such as sugar and salt, will alert the hypothalamus<br />

of a need for water. Have you ever woken up thirsty


Water: The Most Impoflant Nzltrient 61<br />

in the middle of the night after eating a salty meal? Canny<br />

bar owners also bank on this principle by providing salty<br />

snacks to increase thirst so we buy more drinks.<br />

If the mouth and throat are dry it's a dead giveaway we<br />

are thirsty. Some drugs can also cause this sensation.<br />

Diets: the wet and the dry<br />

All sorts of factors influence the amount of water we need.<br />

For instance, taking diuretics for a heart condition will mean<br />

that we wee out lots more fluid. Accordingly, this means we<br />

need extra water. Non-prescription diuretics include alcohol,<br />

tea and coffee. For every one of these consumed, drink an<br />

extra glass of water. Another factor that influences how much<br />

water we need is whether our diet is wet or dry. A wet diet<br />

is full of fruit and vegetables, juices and soups. Five pieces<br />

of fruit will yield an average of half a litre of water. A dry<br />

diet is one full of meat, bread, biscuits, alcohol, coffee and<br />

tea. The former will require us to drink less water than the<br />

latter.<br />

Tap water, filtered water, spring water -<br />

which water?<br />

It would be superb to drink straight from a pure mountain<br />

stream as it cascades down from snowcapped mountain peaks,<br />

or sip the dew from rose petals. Most of us, however, drink<br />

water from the kitchen tap.<br />

In Sydney, the Water Board is cracking down on impurities<br />

in the water supply. Unfortunately there are still a few bugs<br />

that escape the net, including giardia and cryptosporidium,<br />

both of which cause tummy problems including nausea and


62 The Commonsense Gecide to <strong>Eating</strong> <strong>Well</strong><br />

diarrhoea. Ralph Nader, a consumer advocate, from the<br />

Centre for Responsive Law in the United States, found that<br />

more than 2000 chemicals exist in water supplies. Only 30<br />

are tested for. The same is probably true for Australian city<br />

water supplies. It is what is not tested that could be a<br />

problem.<br />

In order to sanitise the water which is supplied to millions<br />

of people, several chemicals are added, some of which may<br />

be detrimental to health, including chlorine and fluoride. Aluminium<br />

was formerly added to reduce cloudiness in the water<br />

and fortunately is no longer used. The problems <strong>with</strong> fluoride<br />

are discussed on page 178. Chlorine is added to the water as<br />

a disinfectant and antibacterial agent. It has been used since<br />

1904, when Sir Alexander Houston demonstrated that chlorine<br />

destroyed typhoid bacillus and cholera. Unfortunately,<br />

chlorine causes oxidation of cells, hence free radical damage.<br />

It also depletes vitamins E, C, A, BIZ and selenium. When<br />

chlorine combines <strong>with</strong> humic acid (from decaying leaves and<br />

soil found in the bottom of water reservoirs), a group of chemicals<br />

known as (trihalomethanes) THM are formed. The best<br />

known is chloroform, once used as an anaesthetic, now<br />

banned due to increased risk of liver and kidney cancer. The<br />

July 1992 issue of the Journal of American PubGic Healtd<br />

reported that people who drink chlorinated water have a 21<br />

per cent increased risk of bladder cancer and a 38 per cent<br />

increased risk of rectal cancer. Chlorine will evaporate if you<br />

leave water in an opened container overnight. Hot showers<br />

increase inhaled chloroform, and don't even think about<br />

indoor council swimming pools.<br />

The truth of the matter is that it is better to drink tap<br />

water than no water at all. And as most of us are walking<br />

around partially dehydrated, the question of which water we<br />

drink takes a lower priority. However, some people are<br />

willing to take the extra steps in order to provide purer water


Water: The Most Important Nutrient 63<br />

for themselves and their families. There are many water<br />

filters available that cater to this need. Choose a water filter<br />

that removes chlorine, bacteria, pesticides and asbestos. The<br />

more expensive models, including reverse osmosis, will also<br />

remove fluoride and heavy metals such as arsenic, lead and<br />

mercury. Spring water is also available and very popular,<br />

although you have to wonder about the environmental consequences<br />

of millions of discarded plastic bottles.<br />

Drink it anyway:you won't regret it<br />

Most people find that their general health improves by drinking<br />

2 litres of water daily. One major complaint is the<br />

increased number of visits to the loo. Your bladder takes<br />

about two to three weeks to get over the shock of all the<br />

extra fluid and after this time will settle down, happy to<br />

expand to meet the new circumstances. If you prefer to drink<br />

mineral water, choose a flat variety rather than the bubbly<br />

varieties. Carbonated water, whether natural or not, interferes<br />

<strong>with</strong> bone calcium and phosphorus ratios and may cause flatulence<br />

<strong>with</strong> the added gas.


BITS AND PIECES


Safe or Fake: Additives,<br />

Organics and Germs in<br />

the Kitchen<br />

Sweet as sweet can be: artificial sweeteners<br />

Artificial sweeteners have been part of the modern diet for<br />

decades. Most were discovered in laboratories by accident.<br />

For instance, cyclamates were discovered in 1937 when a<br />

chemist's ciggie tasted sweet after he was messing around<br />

<strong>with</strong> an experiment. Saccharin was similarly discovered when<br />

a scientist in Johns Hopkins laboratory was munching on a<br />

sandwich. These men's mothers probably despaired of their<br />

son's poor hygiene, but would have been really angry when<br />

they realised that they missed out on mink coats and pearls<br />

because their boys didn't receive the squillions of dollars that<br />

the pharmaceutical companies made from the discovery of<br />

sweeteners.


68 The Commonsense Gzkide to <strong>Eating</strong> <strong>Well</strong><br />

Saccharin, aspartame and sucralose<br />

Artificial sweeteners are classified as food additives and have<br />

insinuated themselves into soft drinks, cake mixes, icecreams,<br />

chewing gum and are added to many cappuccinos<br />

(skinnycinnos).<br />

Saccharin is 300 times sweeter than sugar and contains zero<br />

calories. It has a bitter, metallic aftertaste. In 1977, saccharin<br />

was banned in the United States because various studies<br />

showed that it caused bladder cancer in mice. There was a<br />

public outcry (Americans don't like being compared <strong>with</strong><br />

rodents) and saccharin was reinstated. Cyclamates share a<br />

common history <strong>with</strong> saccharin, however, they are currently<br />

banned from sale. Saccharine and cyclamates are absorbed<br />

from the intestines and enter the bloodstream. Once circulating<br />

in the bloodstream the body has no idea what to do<br />

<strong>with</strong> these foreign chemicals and <strong>with</strong> no biochemical pathways<br />

to travel, these sweeteners exit the body via the kidneys<br />

and into the urine. It is possibly while waiting in the bladder<br />

that the cancer-forming agents are activated.<br />

Aspartame (sold as Nutra Sweet) holds the largest share of<br />

the artificially sweet market. Discovered in 1975 (another<br />

accident, this time during the search for a stomach ulcer<br />

drug), aspartame is a concoction of two amino acids (units of<br />

protein) - aspartic acid (40 per cent) and phenylalanine (50<br />

per cent) - together <strong>with</strong> a molecule of methanol (10 per<br />

cent). Being predominantly protein, aspartame has four<br />

calories a gram, but by a quirk of science tastes 200 times<br />

sweeter than sugar, so that very much less than 1 gam' is<br />

required for even the sweetest tooth.<br />

The two amino acids are broken down and treated accordingly<br />

in the body. Methanol (wood alcohol) forms the poisonous<br />

substance formaldehyde and formic acid. A significant<br />

number of people suffer from side effects from aspartame.<br />

Symptoms include blurred vision, tinnitus, headaches,


Safe or Fake 69<br />

dizziness, memory loss, drowsiness, depression and irritability.<br />

Whether it be from the methanol or the unusual influx<br />

of single amino acids has not been determined. In addition,<br />

people suffering from the genetic condition Phenylketonuria<br />

(PKU) are unable to metabolise the amino acid phenylalanine.<br />

There are warnings to this effect on the labels of food<br />

and drink containing aspartame.<br />

Sucralose tastes like sugar and is chemically similar to sugar<br />

but has a chlorine molecule attached to it. Unlike sugar, it is<br />

not recognised at the site of absorption, the small intestine.<br />

Incapable of being digested, sucralose continues down the<br />

digestive tract where it will be fodder for the bacteria there.<br />

Unaccustomed as they are to a sugar molecule.<strong>with</strong> chlorine,<br />

the presence of sucralose in the bowel will cause an imbalance<br />

to the bowel microflora. Bloating and flatulence are<br />

often the result. If large amounts are consumed there may<br />

well be diarrhoea, as water will rush into the bowel in order<br />

to dilute the concentration of sugar-like molecules. Goodness<br />

only knows the fate of the chlorine molecule, although we<br />

know that chlorine on its own is a potent free radical (see<br />

page 152).<br />

Another group of artificial sweeteners is known as sugar<br />

alcohols. These include mannitol, sorbitol, xylitol and maltitol.<br />

They are commonly found in sugar-free chewing gum.<br />

Sugar alcohols are not absorbed or are absorbed very slowly,<br />

again causing microflora imbalance and diarrhoea.<br />

The case against artificial sweeteners<br />

I do not believe artificial sweetners have any value in a good<br />

diet. First, the foods they are normally added to - ice-cream,<br />

biscuits and carbonated drinks - are best avoided anyway.<br />

Second, they cause bowel disturbances in a large number of<br />

people. Third, they do nothing to change our taste for sugar.<br />

Although it is a natural human instinct to like sweetness,


70 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

refined sugar and artificial sweeteners were never part of the<br />

original plan. If we keep eating sweet food, we will keep<br />

craving sweet food. Most people who swear off sugar are<br />

delighted to find that after a couple of weeks (a month at the<br />

most) they lose their desire for chocolates, cakes and lollies.<br />

An added bonus is that fruit tastes more intense as the fruit<br />

sugar, fructose, registers on jaded tastebuds. Substituting<br />

artificial sweeteners for sugar does nothing to change a habit<br />

of a lifetime.<br />

Fourth, the diabetic market is saturated <strong>with</strong> foods containing<br />

artificial sweeteners. Diabetics are best trying to avoid<br />

a sweet tooth. Encouraging it is cruel.<br />

Fifth, there is evidence linking saccharin to bladder cancer<br />

and aspartame <strong>with</strong> headaches and neurological problems,<br />

although the incidence and risk is low.<br />

Sixth, in my experience people do not lose weight by substituting<br />

artificial sweeteners for sugar. People lose weight by<br />

eating less fat and exercising. In fact, there are several<br />

studies, kept under wraps, which show that people eating<br />

artificial sweeteners tend to put on more weight than those<br />

eating sugar. One theory is that if the body is expecting a<br />

rise in blood sugar levels, as promised by the sweet taste, it<br />

won't stop till it gets a rise in blood sugar. We probably eat<br />

more to compensate.<br />

And finally, a comment on the economic politics of artificial<br />

sweeteners. In a world <strong>with</strong> millions starving for want of<br />

calories (calories are needed to provide energy), we have the<br />

irony of an industry spending huge amounts of money and<br />

resources creating substances that contain no calories or<br />

energy.


Food additives: preserve or punish?<br />

Safe oor Fake 71<br />

Fresh food has a tendency to go off. A fact people have<br />

noticed for thousands of years. And for thousands of years<br />

keen-minded individuals have set about experimenting <strong>with</strong><br />

ways to preserve food. The ancient Greeks burnt sulphur<br />

over their wine. During the Middle Ages in Europe, people<br />

preserved their meat <strong>with</strong> saltpetre (nitrates), something we<br />

still do today.<br />

In the past, it was important to keep a few bits of fruit and<br />

vegetables pickled or candied for the winter. The great sea<br />

voyagers salted away carcasses of meat to last them months<br />

at sea. In cities of millions of people, everyone eating food<br />

as soon as it is picked is an impossibility. In addition, we<br />

think it is our right to eat food that is out of season. This is<br />

achieved either by expensive freighting or by using hot-house<br />

technology.<br />

The microscope identified microorganisms - moulds and<br />

yeasts (fungi) and bacteria - as the cause of fermentation and<br />

putrefaction and confirmed them as likely candidates for<br />

sending food off. Mould and yeast love sugar and head for<br />

carbohydrate foods such as fruit and bread, while bacteria are<br />

inclined towards protein, infesting meat, chicken and eggs.<br />

Microorganisms prefer a steady environment, one that<br />

sounds like a holiday brochure: plenty of food (protein and<br />

carbohydrate); not too hot nor too cold (around 37 degrees<br />

Celsius); plenty of fresh air (most microorganisms are aerobic,<br />

meaning they need oxygen); and go easy on the acid (preferring<br />

an alkaline environment). (Also see food safety on<br />

page 74).<br />

Additives to preserve, to enhance, to tart up<br />

Food additives are not only for preserving food but are used<br />

to facilitate many aspects of the production, handling and


72 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

processing of our tucker. The official definition of a food<br />

additive is 'any substance not normally consumed as a food<br />

by itself and not normally used as a typical ingredient of a<br />

food, whether or not it has nutritive value'. There are food<br />

safety requirements that call for the labelling of foods containing<br />

additives. They are often given a numeric code such<br />

as 210, which stands for benzoic acid. If you are concerned<br />

or allergic to food additives, pick up a food additive code<br />

breaker from your newsagent or bookshop.<br />

Preservatives (200 to 299)<br />

Preservatives aim to inhibit the growth of germs, using a<br />

variety of methods. Antioxidants are sometimes used to<br />

prevent free radicals from damaging food. Free radicals can<br />

cause, among other things, rancidity (butter becomes rancid)<br />

and oxidisation (fzuit that turns brown). Synthetically derived<br />

antioxidants such as BHT may be used or antioxidant nutrients<br />

including vitamins E and C.<br />

The yellow, smelly mineral sulphur or sulphur dioxide is<br />

often added to wine, beer, jams and dried fruit to prevent<br />

microbial growth and oxidation. Sulphur-dried apricots are<br />

always more brightly coloured than their shrivelled sun-dried<br />

cousins. The down side is that some people are allergic to<br />

sulphur and may suffer from asthma or other problems after<br />

consuming it. Sodium metabisulphate is used to clean bottles<br />

and is present in most wines. When you pull out the cork,<br />

sulphur dioxide is released.<br />

Nitrates have been used for centuries to preserve the likes<br />

of salamis and other deli meats. Not only do they protect<br />

against deadly bugs causing botulism, they also give dead<br />

meat a rosy hue. The problem here is that when nitrates<br />

come in contact <strong>with</strong> protein in the body they form nitrosamines,<br />

which are considered to be carcinogenic. Drop that<br />

salami sandwich immediately.

Other preservatives include benzoic acid, paraben, sorbic<br />

acid and nisin.<br />

CoIourfng (100 to 180)<br />

The use of colour additives has been banned in Norway since<br />

1978, which must make their fairy bread and Smarties boring.<br />

Adding colour to food is purely cosmetic and can be quite<br />

deceptive. For instance, a completely synthetic dessert can<br />

be called strawberry flavour even though it has never clapped<br />

eyes on a piece of fruit. Tartrazine (102) is a yellow food<br />

colouring that can cause skin rashes and asthma in sensitive<br />

individuals. Ironically, some of the 'natural' colouring additives<br />

such as annatto may cause more allergic reactions than<br />

the synthetic additives.<br />

Flavouring<br />

Flavouring is added to give bland and indifferent food a bit<br />

of character or restore flavour lost in processing. Flavouring<br />

additives are not given code numbers because they are often,<br />

like Coca Cola 'secret recipes'. Artificial sweeteners are<br />

another type of flavour enhancer (see page 67).<br />

Processing agents<br />

In order for processed food to look the same, pour the same,<br />

mix the same every time, all sorts of chemicals need to be<br />

added. For example, anti-caking agents are used to control<br />

the free-flowing nature of powdered foods such as icing sugar,<br />

salt and milk powder. Sodium silico aluminate (containing<br />

aluminium) is sometimes added in free-running salt; bleaching<br />

agents including chlorine or peroxide are used to achieve<br />

a consistent white colour in flour; humectants such as glycerol<br />

are added to prevent food like bread from drying out; thickeners<br />

and vegetable gums are used to modify the consistency<br />

of food; and emulsifiers are used to overcome the perennial


74 The Comomense Gzcide to <strong>Eating</strong> <strong>Well</strong><br />

problem of mixing oil <strong>with</strong> water. Lecithin is a commonly<br />

used emulsifier - no health threats here for a change.<br />

The bottom line<br />

The bottom line is that we, as consumers, expect our food to<br />

be consistent. For this to occur, food additives are used. We<br />

either cop it sweet, or are willing to pay more for organic<br />

produce that has not been tampered <strong>with</strong>, or we grow or make<br />

our own.<br />

Food safety: not in my kitchen you don't<br />

If you know about Mr Acidophilus and co. (see pages 34-3,<br />

then you are probably quite fond of bacteria, particularly<br />

bowel bacteria. So it's hard to accept that some bugs are out<br />

to kill us, or at least make us sick to the stomach.<br />

There are estimated to be two million cases of food poisoning<br />

in Australia each year. Most at our own hands! While<br />

most food poisoning is merely a day or two of diarrhoea and<br />

perhaps a course of antibiotics, sometimes these bugs are<br />

deadly, particularly for those more vulnerable, which includes<br />

the elderly, children and the immune suppressed.<br />

Food safety is seldom taught in schools. My only education<br />

about food safety and kitchen hygiene came from 1960s<br />

women's magazines. By the mid-1970s, these magazines were<br />

full of information on finding one's G-spot or making beef<br />

wellington and crepe suzettes. The days of aprons and food<br />

safety tips were gone. Not so for the generations of bacteria,<br />

viruses and fungi that lived on through the swinging '60s,<br />

sexy '70s, merchant banking '80s into the enviroconscious<br />

'90s and beyond. More education is needed.

breed at the drop of a hat, usually by dividing in half.<br />

Their favourite motto is 'divide and conquer'. Family gettogethers<br />

in theory are identical brothers and sisters.<br />

Salmon& Not a female fish, but a bacteria that is<br />

responsible for the majority of food poisoning outbreaks<br />

in Australia. Safmonella causes gastro-type symptoms,<br />

including nausea and vomiting which in the weakened<br />

can result in death. Outbreaks have been recorded<br />

mainly from raw meats, poultry and dairy products, but<br />

also peanut butter, desiccated coconut, chocolate and<br />

eggs. Most outbreaks occur through cross-contarnination<br />

from raw food to cooked food.<br />

This little critter is found mainly in pre-cooked foods, especially<br />

starchy vegetables, rice, sauces, puddings and meat<br />

and can even grow in the fridge. For this reason, precooked<br />

food should not be stored in the refrigerator for<br />

more than two to three days.<br />

Staphylococcus aureus OAen found halfkay up our<br />

nostril, this bug is a normal inhabitant. Infected cuts and<br />

sores also contain large numbers and together <strong>with</strong><br />

sneezing on food, these are common ways in which<br />

infection spreads. Violent abdominal cramps, nausea.<br />

vomiting and diarrhoea are symptoms which may<br />

appear very quickly, from one to six hours after eating<br />

the infected food. Foods commonly implicated include<br />

ham, frankfurters, cream-fded bakery products and<br />

some cheeses.<br />

Campylobacter jejud A relatively common cause of<br />

food poisoning, so you'd think it would do us the courtesy<br />

of adopting an easy-to-pronounce nickname like<br />

'carny' or 'CJ'. Outbreaks of CJ have been linked to the<br />

consumption of undercooked poultry, mince and sausages<br />

and cooked poultry which has been contaminated<br />

by raw poultry (cross-contamination). Diarrhoea and a<br />

fever may appear two to seven days after eating the<br />

offending food, and this time delay makes diagnosis a<br />

bit tricky. Some people contract a kind of arthritis that<br />

may last weeks to months.<br />

Other less common microorganisms that cause food<br />

poisoning include E. coE, Listeria monocyfogenes and<br />

CIostridum botrrlinum.

How bacteria breed and spread and what to do<br />

about it<br />

Hot Is hot, cold is cold<br />

As a rule, bacteria are sensitive little fellows, particularly to<br />

temperature. If it is too cold or too hot they either die or<br />

keep a very low profile. If food is kept in the 'danger zone',<br />

that is, between 6 and 100 degrees Celsius, this is where the<br />

trouble begins. Bacteria flourish and multiply, doubling in<br />

number in as little as 20 minutes.<br />

Cold food should be kept really cold in the refrigerator -<br />

4 degrees Celsius and under. Take perishable foods such as<br />

meat, poultry, milk and seafood home immediately after purchase.<br />

Buy these foods last on your shopping trip. If you are<br />

likely to take more than one hour getting home, invest in an<br />

esky or cool container to store the food before you can put it<br />

in the fridge.<br />

Put leftovers in the fridge or freezer promptly after eating.<br />

Don't leave them on the counter top to cool down overnight.<br />

Cook foods to at least 100 degrees Celsius - boiling<br />

point - as this will kill most bacteria and viruses that can<br />

cause illness. One way to tell for sure is to invest in a meat<br />

thermometer. This applies to reheating food as well. Make<br />

sure the food is cooked or heated throughout. This is particularly<br />

important for mince, sausages and chicken. Steak is<br />

okay undercooked. Microwave ovens tend to cook food<br />

unevenly, even on a turntable. Make sure you mix the food<br />

once or twice during cooking.<br />

Soap and water<br />

Most of us feel that a quick rinse of the hands under the cold<br />

tap is all that is needed. Not so. Wash hands <strong>with</strong> soap and<br />

warm water for 20 seconds before handling food. This is especially<br />

important when handling raw meat, poultry or seafood.


78 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

Keeping hands, benchtops and washing cloths squeaky<br />

clean is of paramount importance. There are antibacterial<br />

solutions available. In addition, you might like to add a few<br />

drops of eucalyptus, lemon or lavender oil to rinsing water<br />

for washcloths and when wiping down benches. These essential<br />

oils not only smell clean, they are antibacterial.<br />

From me to you: cross-contamination<br />

Cross-contamination occurs when bacteria transfer from one<br />

food to another. For instance, placing a cooked steak on the<br />

same plate that held it before cooking, allows the bacteria in<br />

the juices from the raw steak to infect the cooked.<br />

Another cross-contamination scenario happens when we<br />

store raw food (particularly meat or poultry) in the fridge<br />

above cooked food, allowing the juices to drip down.<br />

Throw in the towel<br />

For those who hate drying the dishes, this is a great reason<br />

to throw in the towel. The dirty teatowel, that is. Either leave<br />

the dishes to dry naturally or buy a dishwasher! Don't throw<br />

a dirty teatowel over the rack of dishes. Change teatowels<br />

and dishwashing cloths regularly.<br />

Cutting boards are a common cause of cross-contamination,<br />

particularly when using the board after preparing raw meat,<br />

poultry or seafood. Give them a good scrub <strong>with</strong> detergent<br />

in hot water. If you have wooden chopping boards, one way<br />

of being sure you have killed any bugs is to pop the board<br />

into the microwave for three minutes. Unfortunately, this is<br />

not effective for plastic cutting boards.<br />

I think I thaw it in the fridge<br />

Don't take short cuts. Never thaw or marinate meat, seafood<br />

or poultry out of the fridge. Almost half of Australians defrost<br />

their food on the benchtop or under running water. Plan


Safe or Fake 79<br />

ahead and thaw your food in the fridge. It may take longer,<br />

but it is a safer method. If you choose to defrost using the<br />

microwave, make sure you cook the food straightaway.<br />

When in doubt, throw it out<br />

Those sneaky little microorganisms have many tricks up their<br />

tiny sleeves and other articles of apparel. One of them is their<br />

'cloak of invisibility'. Not only can we not see them, but we<br />

cannot smell, hear or even taste them. When in doubt, throw<br />

it out. Or give it to the dog, whose stomach is usually hardier<br />

than our own.<br />

Lie and let a few live: freedom to the bugs<br />

Don't let all this disinfecting turn into an obsessive compulsive<br />

disorder. Take reasonable steps to thwart microorganisms. On<br />

the other hand, it is illogical to expect that our environment is<br />

microorganism free, when in and on ourselves are literally billions<br />

of bugs. If our internal bugs are content, we should be<br />

able to live in harmony <strong>with</strong> our environment (see probiotics,<br />

page 34). <strong>Eating</strong> probiotic foods such as yoghurt, in addition<br />

to taking reasonable food safety precautions, will improve our<br />

resistance against food poisoning.<br />

If you are using disinfectants, make sure that you rinse<br />

cutlery and crockery very well. The disinfectant may be<br />

aimed at bad bugs, but if you swallow the stuff, it will also<br />

kill good bugs in the gut.<br />

Organic shmorganic: chemical free<br />

It took agent orange and the massive backdown of cigarette<br />

companies to verify that toxic chemicals are dangerous,<br />

whether we touch them, inhale them or eat them. Many conditions,<br />

including Chronic Fatigue Syndrome, cancer and<br />

various auto-immune conditions seem to be closely linked<br />

<strong>with</strong> an excess of chemicals and sufferers are especially<br />

sensitive to the chemicals used in farming. Although we are<br />

becoming more aware of the dangers of toxic chemicals, as<br />

individuals we can do little about the pollution and paint<br />

fumes we breathe. However, we can choose what we put in<br />

our mouth. For this reason, organic farming has spread from<br />

a wacky, hippie pursuit to mainstream agriculture. Today you<br />

can buy organic rice and flour at the supermarket, unheard<br />

of five years ago.<br />

Organic farming combines modern scientific principles<br />

<strong>with</strong> old knowledge and traditions. 'Organic' means farming<br />

<strong>with</strong>out the addition of artificial chemicals used in (a) preparing<br />

the soil, (b) growing the crop or (c) storing and<br />

marketing the produce. Non-organic produce is frequently<br />

sprayed <strong>with</strong> pesticides, fungicides and so on. Organic<br />

animals are allowed to range as freely as possible, and are fed<br />

organic grains and produce.<br />

In Australia we have several regulatory organisations,<br />

including the National Association for Sustainable Agriculture<br />

(NASAA), Biological Farmers of Australia (BFA) and the<br />

Bio-Dynamic Farmers of Australia (Demeter). These groups<br />

monitor the organic farms and their produce. Basically there<br />

are three main categories of organic-ness. The first or highest,<br />

come from farms that use no artificial fertilisers or synthetic<br />

chemicals and have not done so for more than two years. The<br />

second stage, sometimes called 'conversion', is similar but has<br />

been that way for less than two years. The third level, 'sustainable',<br />

means that a minimum of non-toxic sprays have<br />

been used under strict guidelines.


Safe or Fake 81<br />

Although organic produce costs more, it is environmentally<br />

friendly and studies have shown that the produce contains<br />

more micronutrients than those produced under mainstream<br />

farming practices.


OUR DAILY FOOD


The Food We Eat<br />

Nuts, seeds and oils<br />

A nut, and we've all known a few, refers to the shell-encased<br />

single seed of a tree. If you have ever been the recipient of<br />

the school joke about peanut trees, you will be aware that<br />

peanuts are not nuts, but legumes. Nevertheless, peanuts are<br />

de facto nuts. Both seeds and nuts are high in fat and in their<br />

processed form as 'vegetable' oil, are the source of most of<br />

the oils we consume, <strong>with</strong> the exception of olive oil, which<br />

comes from the olive fruit. Fat is vital to our health, necessary<br />

for hormones, cell membranes and so much more. People<br />

who live fat free tend to look desiccated and vaguely<br />

unhappy. Much better to look healthy <strong>with</strong> the glowing skin<br />

and shiny hair that only good quality fats found in nuts and<br />

seeds can provide.<br />

Because nuts, seeds and oils are high in fat, they are susceptible<br />

to becoming rancid (see oil processing, page 51). We


86 The Common~se Ggide to <strong>Eating</strong> <strong>Well</strong><br />

can minimise this by buying them in small quantities from<br />

shops that have a high turnover. Keep them covered in dark,<br />

cool containers, such as a fridge. Cold-processed oils retain<br />

more vitamins and have less chance of containing oxidised<br />

fatty acids (a big cause of free radicals in the body). Be aware<br />

that cold-processed oils taste stronger and look more cloudy<br />

than their processed-beyond-belief cousins.<br />

ALMOND<br />

The almond tree blossoms a treat, just like its relatives the<br />

cherry, peach and apricot trees. Almonds have plenty of<br />

essential fatty acids, potassium, calcium, iron, zinc and<br />

vitamin E. Almond paste, made in the same way as peanut<br />

butter, put through a grinder, is a scrumptious spread on toast<br />

for breakfast. Marzipan, originating from the Middle East, is<br />

made from ground almonds, sugar and egg white.<br />

B ~ R<br />

Butter is included here because of its oil status. Butter is<br />

churned from cream, the fattier part of milk. In Australia,<br />

butter is made from cow's milk but it can also be made from<br />

other animals, including the buffalo and yak. Butter is mostly<br />

saturated fat but contains a tiny portion of milk protein and<br />

sugar. Salt is often added in the processing. Butter provides<br />

us <strong>with</strong> vitamins A and D, and can play a small part in a good<br />

diet.<br />

BRAZIL NUT<br />

Brazil nut trees (native to - you guessed it) grow up to 30<br />

metres tall. Brazil nuts are slightly higher in fat than almonds<br />

but contain the amino acid methionine, which helps the liver<br />

metabolise fats. They are a reasonably good source of protein;<br />

good news for vegans.


The Food We Eat 87<br />

CASHEW<br />

Slightly lower in fat than other nuts, cashews are also a good<br />

source of potassium, iron and zinc. The cashew is a distant<br />

relative to poison ivy and cashew shells contain a nasty substance<br />

that burns your skin, which is why cashews are always<br />

sold naked.<br />

CHESTNUT<br />

Chestnuts have never really been a hit in Australia. Maybe<br />

because our climate doesn't get cold enough (sorry Tasmania)<br />

for it to be sold over fires on street corners. The chestnut<br />

was once used as a major food source before the potato hit<br />

the market in Europe in the sixteenth century. Chestnuts<br />

have about one-third the fat of other nuts and much more<br />

starch.<br />

COCONUT<br />

Maybe because of its size, we seldom think of the coconut<br />

as a nut. Coconuts give so much of themselves: milk, oil and<br />

flesh. Coconut oil is made up of mainly saturated fats, which<br />

make it a very stable cooking oil.<br />

HAZELNUT<br />

Hazelnuts are also known as filberts, which sound more like<br />

a friendly chipmunk or a computer nerd than a nut. Hazelnuts<br />

are used in the creation of the liqueur Frangelico but they<br />

have other uses as well. They provide similar nutrients to<br />

almonds and are another nut that is lovely ground as a paste<br />

on toast for breakfast.<br />

LINSEED<br />

Linseeds are also known as flax seeds. Linseeds have uses<br />

other than as a food source, including providing fibre for cloth<br />

and oil for polishing wood, particularly cricket bats. The seeds


88 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

contain lignans that have phyto-oestrogen effects useful for<br />

controlling the symptoms of menopause. Ground linseeds are<br />

also very good for constipation and, due to the softening<br />

action of the linseed fibre, help conditions such as diverticulitis<br />

and colitis.<br />

Often recommended to treat conditions such as eczema<br />

and PMS, cold-pressed linseed oil is prized for its content of<br />

omega-3 and omega-6 fatty acids. Just make sure you don't<br />

buy the furniture oil variety instead.<br />

Macadamia nuts are expensive because their shells need jackhammers<br />

to open them. Macadamias are actually native to<br />

Australia. It is just because those canny Hawaiians covered<br />

them in chocolate and put them in fancy tins everyone thinks<br />

they are from the fiftieth state. They have a high fat content,<br />

even for a nut, and don't offer much in the way of micronutrients.<br />

Macadamia oil makes a very nice massage oil and<br />

moisturiser.<br />

OLIVE<br />

Olives are one of a few fruits that store energy as oil. Raw<br />

olives are very bitter and need to be soaked in a salty solution<br />

to remove some of the bitterness. Olives and their oil have<br />

been around for some time. 'And the dove came in to him in<br />

the evening: and, lo, in her mouth was an olive leaf pluckt<br />

off (Genesis, 8, xi).<br />

'Extra virgin' olive oil is the prized oil that comes from the<br />

first pressing. Generally, the darker and dirtier-looking the<br />

olive oil, the purer it is. Other olive oils such as pure or virgin<br />

are from subsequent pressings. There is nothing 'light' about<br />

light olive oil except its colour, which means that it has<br />

undergone excessive processing. Avoid it.


The Food We Eizt 89<br />

PEANUT<br />

Peanuts snuck into the nut category (although they are botanically<br />

a legume) and much to the chagrin of proper nuts, are<br />

the most popular of the lot. Peanuts are a little lower in fat<br />

than nuts and are reasonably high in protein. Fresh-ground<br />

peanut butter is quite a delightful food. However, some<br />

people have been known to eat large containers at a sitting.<br />

Shame.<br />

Peanuts receive a lot of bad press and not merely because<br />

of the deception regarding their nut status. They are a<br />

common allergen, causing skin and breathing problems<br />

among the susceptible. In addition, they often grow a mould<br />

called AspqiZZus flavus, which produces a poison called<br />

aflatoxin. Aflatoxin is 20 times more toxic than DDT. The<br />

Department of Agriculture issue guidelines as to minimum<br />

quantities of aflatoxin, nevertheless, there is always a little<br />

present.<br />

PUMPKIN SEEDS<br />

Don't throw them out. Baked pumpkin seeds taste very good.<br />

Pumpkin seeds are high in zinc and are good in preventing<br />

and treating prostacic problems (see pumpkin on page 100).<br />

Put them on the male member of the family's plate, covered<br />

in gravy, so he eats them before realising. People <strong>with</strong>out<br />

prostates can also indulge in pumpkin seeds because of their<br />

zinc and essential fatty acids.<br />

SESAME SEEDS<br />

Sesame seed oil is used extensively in Asian cooking. Try<br />

buying the cold-pressed variety as the taste enhances any stirfrying<br />

or cooking. Sesame seeds contain reasonable amounts<br />

of lignan, the plant hormone substance so good for menopause<br />

symptoms. Tahini is a paste made from ground sesame<br />

seeds and is a frequent ingredient in many Middle Eastern


90 The Commonsense Guide to Eahg WeZi<br />

dishes. Tahini makes a very nice spread on bread: try substituting<br />

it for butter on salad sandwiches.<br />

SUNFLOWER SEEDS<br />

Sunflower seeds taste good on their own or thrown on top of<br />

salads. A delicious snack is to toss a handful of sunflower<br />

seeds onto a heated cast-iron pan, move them round a little<br />

<strong>with</strong> a wooden spoon so that they brown but do not burn.<br />

Just as they begin to brown pour in a tiny amount of low-salt<br />

soy sauce. Take off the heat immediately. Cold-pressed sunflower<br />

oil contains good quantities of essential fatty acids.<br />

WALNUT<br />

Walnuts are the most nutritious of nuts <strong>with</strong> plenty of vitamin<br />

E, calcium, iron and zinc. Walnuts have been found to lower<br />

cholesterol levels.<br />

Herbal tea<br />

As a herbalist I generally prescribe herbal tinctures or tablets.<br />

For some conditions, however, nothing beats a herbal tea,<br />

because of the release of therapeutic volatile oils, which are<br />

not available to the same extent from tinctures or tablets. I<br />

rely on teas such as buchu, cornsilk and uva ursi for urinary<br />

tract problems. Fenugreek and golden rod are good for mucus<br />

congestion such as sinusitis. Tea made from catmint, passionflower<br />

and hops is excellent for sleeping. Herbal concoctions<br />

of burdock, echinacea and red clover teas are terrific blood<br />

purifiers; good for skin problems like pimples and eczema.<br />

Herbs have been used as medicine for as long as plants<br />

and humans have been together on earth, and some herbs are<br />

pretty potent. Just as you wouldn't take Aunt Martha's heart<br />

tea that may have a strong effect <strong>with</strong>out professional advice.<br />

For instance, one little cup of senna pod tea could have you<br />

on the loo all night. Generally, herbal teas sold in supermarkets<br />

and health food shops are fine. But if in doubt, ask.<br />

Herbal tea tips<br />

Supermarkets usually carry a range of herbal teas in<br />

handy teabag form. If you are a herbal tea novice buy<br />

a small packet or a sampler packet until you have<br />

decided on your favourites.<br />

In general, herbal teas do not require milk. The exception<br />

could be dandelion root, cinnamon and ginger.<br />

Honey is another option that suits some people and<br />

some teas more than others.<br />

Use pure water to make your teas.<br />

Use one teaspoon of dried herb (two teaspoons of<br />

fresh herb) per cup of boiling water. Pour boiling<br />

water over herb in enclosed container; for example,<br />

a teapot or infuser.<br />

Chop the leaves and stems of fresh herbs to increase<br />

the surface area and release volatile oils.<br />

Keep any excess tea in the fridge and consume <strong>with</strong>in<br />

24 hours.<br />

The following herbal teas may be drunk freely, say up to five<br />

cups a day. However, try to develop a taste for herbal teas<br />

and drink a variety.<br />

CHAMOMILE<br />

Chamomile is gentle enough for babies and the very elderly.<br />

It is a particular favourite in Germany where it is accepted as


92 The Commonsense Gzlide to <strong>Eating</strong> <strong>Well</strong><br />

a standard variant for tea or coffee. It helps calm the nervous<br />

and digestive systems, which makes chamomile the obvious<br />

choice for those whose digestion is affected by stress. It is<br />

also good to drink if you suffer period cramps. Allointoin is a<br />

chemical derived from chamomile that is anti-inflammatory<br />

and healing. Chamomile tea is recommended as a final hair<br />

rinse for blondes (cool the tea first, this is not intended as a<br />

'blonde' joke). Chamomile blends well <strong>with</strong> a slice of fresh<br />

ginger root.<br />

PEPPERMINT<br />

Peppermint tea is excellent to settle your tummy after a big<br />

meal. The menthol gives it an uplifting flavour and fragrance<br />

although it is not a stimulant in the sense of coffee or tea.<br />

Peppermint is good for any digestive problems, particularly<br />

nausea, bloating, flatulence and the symptoms of irritable<br />

bowel syndrome.<br />

On hot days cool your paws in a bucket of water <strong>with</strong> a<br />

few drops of peppermint oil added (never drink essential<br />

oils). Chilled peppermint tea is also cooling. Women who<br />

suffer from hot flushes and sweating during menopause will<br />

benefit from sipping cool peppermint tea.<br />

ROSEHIP<br />

Rosehip tea, made from the fruit of the wild dog rose, has an<br />

interesting, tart flavour and is a dreamy berry colour. Rosehips<br />

are an excellent source of bioflavonoids and this is probably<br />

why it has earned its reputation as a winter tea to keep colds<br />

and flu away. Rosehip tea is slightly astringent and may be<br />

helpful in mild diarrhoea. Rosehip tea combines well <strong>with</strong> a<br />

strong-tasting honey such as leatherwood.

DANDELION ROOT<br />

Dandelion root tea is often recommended as a substitute for<br />

coffee, which is rather cruel as the only things it has in<br />

common <strong>with</strong> coffee is that it is black and hot. However,<br />

dandelion root is very, very good for you, particularly your<br />

liver, and it is well worth acquiring a taste for this bitter herb.<br />

If you are using chunks of dandelion root you will need to<br />

boil them for a few minutes; they can also be reused a couple<br />

of times. Sometimes you can find finely ground dandelion<br />

root, which you can use in the same way as coffee powder:<br />

percolate or infuse. The instant version of dandelion root tea<br />

is usually sweetened <strong>with</strong> lactose and tastes a bit sickly. Some<br />

people add soy milk to their dandelion. It is up to you.<br />

Dandelion leaves are rich in minerals, including potassium,<br />

and they are extremely diuretic. Only drink dandelion leaf<br />

tea if that is the effect you are after. It is beneficial for women<br />

who retain fluid around period time.<br />

LEMON GRASS<br />

Lemon grass tastes very different depending on whether you<br />

use fresh or dried. The flavour is tangy and lemony due to<br />

the citrus-flavoured oil known as citral. Growing lemon grass<br />

in a pot or garden is easy. Similar to African violets, it takes<br />

a lot to kill a lemon grass plant. If you have one growing,<br />

snip off what you need for a cup of tea just as you put the<br />

kettle on. Fresh lemon grass is often available at fruit shops<br />

in the herb section. Buy one or two stalks and keep them in<br />

the freezer. Dried lemon grass can also be used. Personally,<br />

I prefer it fresh. Lemon grass combines well <strong>with</strong> ginger,<br />

lemon and honey.<br />

NETTLES<br />

Nettles are still cooked as a vegetable in some parts of the<br />

United Kingdom. The leaves need to be boiled so that the

to <strong>Eating</strong> <strong>Well</strong><br />

nasty little spikes don't cause internal damage. Nettle tea has<br />

long been used as a tonic, possibly due to its high mineral<br />

content, rich in iron. If you suffer from eczema or dermatitis,<br />

drink the tea and make extra to use as a soak. Nettles are<br />

very good for any itching and inflamed skin condition. It is<br />

also widely recommended as a final hair rinse for brunettes.<br />

FENUGREEK<br />

These mustard-coloured seeds have an earthy, pungent<br />

odour. Fenugreek has diaphoretic properties, which means it<br />

makes you sweat: one of the natural mechanisms our bodies<br />

have for clearing out the junk. Fenugreek is an excellent lymphatic<br />

cleanser and can be a powerful adjunct to an internal<br />

spring-cleaning routine. Fenugreek is safe to drink during<br />

pregnancy and will improve milk flow during lactation. Fenugreek<br />

tea helps clear mucous from the sinuses, throat and<br />

nose. Fenugreek also helps to stabilise blood sugar levels.<br />

Great for people <strong>with</strong> a sugar craving. A dab of honey and<br />

squeeze of lemon may be added if desired.<br />

RASPBERRY LEAF<br />

Raspberry leaf tea doesn't taste as yummy as it sounds but<br />

it's not too bad. A tea often recommended during the latter<br />

third of pregnancy to 'tone' the uterus. It is also good for<br />

heavy periods. Drink two or three cups daily. Raspberry leaf<br />

tea can also help quell a nauseous tummy and is also useful<br />

for diarrhoea.<br />

THYME<br />

Thyme is quite a pleasant tea <strong>with</strong> very antiseptic qualities.<br />

Only use fresh (or freshly frozen) thyme as the volatile oils are<br />

in abundance in the fresh leaves. It is a good tea if you have a<br />

chesty cold or lung infection. Gargle when cool to relieve a sore<br />

throat or tonsitilitis. Not one to drink all the thyme!


The Food We Eat 95<br />

The classic 'cold' tea incorporates thyme. Chop two to<br />

three inches of fresh root ginger, a cinnamon stick, the juice<br />

of one lemon, rind of half a lemon, a few sprigs of fresh thyme<br />

and honey. Fill the pot or plunger <strong>with</strong> freshly boiled water<br />

and drink a few cups to help you through the day.<br />

Sage is a very astringent tea. Use the fresh leaves if you can,<br />

although dried will do at a pinch. A strong, cool sage gargle<br />

will help kill any bugs in the throat. Sage contains phytohormones<br />

and is often recommended as a cool drink for<br />

women suffering the hot flushes of menopause. Drink two to<br />

three cups daily for about a month.<br />

GINGER<br />

Ginger makes a very warming winter brew and it is excellent<br />

for a sluggish circulation. Anyone who feels the cold will<br />

benefit from ginger. Ginger is also an effective digestive<br />

remedy, particularly good for nausea.<br />

Fresh ginger root is best. Take a 2- or 3-centimetre bit of<br />

root. Peel or wash the outside then chop into little bits. You<br />

can throw this into a teapot or infuser, or simply place a<br />

couple of thin slices in the bottom of your cup.<br />

LEMON JUICE<br />

Hot water <strong>with</strong> a sqeeze of lemon is quite pleasant and very<br />

good for the liver. It is even nicer <strong>with</strong> a teaspoon of honey.<br />

A teaspoon of brandy or rum can add interest too, although<br />

not recommended for liver health.<br />

CAROB<br />

The finely ground carob bean pod makes quite a decent<br />

drink: a bit like a Clayton's hot chocolate. Carob is a rich


96 The Commonsense Guide to <strong>Eating</strong> Wen<br />

source of minerals, particularly calcium. I like it <strong>with</strong> a sprinkle<br />

of cinnamon, honey and a touch of milk.<br />

Vegetables<br />

How very boring when you find that your parents were right.<br />

It helps a little that they don't know how to surf the Net but<br />

it's darn annoying about those vegetables. It is a fact that<br />

people who eat more vegetables have less cancer, constipation,<br />

heart disease and diabetes. Not only are vegetables low<br />

in fat, they have plenty of fibre <strong>with</strong> vitamins and minerals<br />

to spare. Australians eat an average of 3 kilograms of vegies<br />

per week, <strong>with</strong> at least 1 kilogram in potatoes. Unfortunately,<br />

a number of these potatoes have been transmogrified into<br />

chips, which defeats the purpose slightly. To save the vitamins,<br />

vegetables should be cooked <strong>with</strong> care (not boiled to<br />

death) or even eaten raw.<br />

ASPARAGUS<br />

Asparagus are slim and elegant vegetables; the supermodels<br />

of the vegetable kingdom. Not surprising, as they are part of<br />

the absolutely fabulous Lily family. Until I was in my twenties,<br />

I never realised you could buy asparagus except in a can,<br />

overcooked and oversalted. When I discovered the fresh<br />

version I became a convert. Asparagus contains an amino acid,<br />

asparagine, which is responsible for the almost immediate<br />

effect on the smell of urine.<br />

BEANS<br />

Green beans are actually a legume <strong>with</strong> a fleshy covering.<br />

They are good for the kidneys and bladder.

BROCCOLI<br />

Part of the cabbage family, broccoli, like its smelly brothers,<br />

has anti-cancer nutrients (indoles) by the bucketload. Broccoli<br />

also has significant amounts of vitamin C, as long as it has<br />

not been cooked forever. Anything dark green like broccoli<br />

has loads of chlorophyll, that wonderful life-giving substance<br />

that helps plants produce energy from sunlight.<br />

BRUSSELS SPROUTS<br />

Similar to broccoli, and even more despised by youngsters,<br />

brussels sprouts contain similar nutrients and anti-cancer<br />

potential.<br />

CABBAGE<br />

Introduced to Europe by the Celts, cabbage is the most commonly<br />

used vegetable and the longest cultivated. Common it<br />

may be but cabbage is uncommonly good for us. It is full of<br />

antioxidant nutrients - indoles. Red cabbage has the added<br />

advantage of containing the pigment antioxidant similar to<br />

red grapes - anthocyanin.<br />

Cabbage juice is wonderful for the healing of stomach<br />

ulcers. Don't be a martyr and drink it straight, mix it half/<br />

half <strong>with</strong> carrot juice.<br />

Cook cabbage <strong>with</strong> a few caraway seeds to dispel the wind<br />

in your belly. The longer cabbage is cooked, the more<br />

cabbagy it tastes. Cabbages are never grown near grapevines<br />

for fear of the taste contaminating the grapes. The outer<br />

leaves of a chilled cabbage worn inside the bra are very good<br />

for the swollen breasts of mastitis. And kake a very elegant<br />

fashion statement.

CARROT<br />

Carrots are the richest source of beta-carotene (pro-vitamin<br />

A). Did you know carrots were originally purple or black? The<br />

orange variety we have come to love is really a mutant!<br />

CAULIFLOWER<br />

Cauliflower is another of the ubiquitous cabbage family.<br />

Because it is white, cauliflower does not contain as many<br />

carotenes and chlorophyll as coloured vegetables. But it does<br />

contain boron, a mineral important for calcium being properly<br />

utilised in bone.<br />

CELERY<br />

Celery is rich in potassium and sodium. Towards the flowery<br />

ends, the celery is bitter. This is good: more bitter means it<br />

is good for the liver and digestive processes. Celery is used<br />

as a diuretic and celery seed extract can be helpful in the<br />

treatment of arthritis.<br />

CUCUMBER<br />

Cucumbers are very cooling for the hot person, or for the<br />

person eating hot, spicy food. Cucumber skin, usually thrown<br />

out, is a good source of silica, good for the quality of bones,<br />

hair, skin and nails.<br />

GARLIC<br />

Hippocrates, Aristotle, Pliny, in fact all the gang recommended<br />

garlic for all sorts of ailments. And it tastes great <strong>with</strong><br />

pasta. As much a herb as vegetable, we would be much poorer<br />

<strong>with</strong>out the health-giving gifts of garlic.<br />

Garlic helps lower blood pressure and cholesterol;<br />

enhances the immune system; is antibacterial, antifungal,<br />

anti-worm (anthelmintic); and it helps eliminate heavy metals<br />

such as lead from the body.

The darker the leaf, the more nutrients. Unfortunately, this<br />

leaves the common iceberg lettuce at the bottom of the nutrient<br />

barrel. All lettuces are a good source of chlorophyll.<br />

MUSHROOM<br />

Mushrooms are not strictly vegetables but a fungus. Mushrooms<br />

are a good source of vitamins and minerals. They are<br />

sometimes represented as containing vitamin BIZ. They do<br />

not. The only way BIZ could be present is from animal<br />

compost that has become lodged in the fan-like underflesh.<br />

ONION<br />

Onions are part of the same Li~~i;:y as garlic and share many<br />

of garlic's health-giving benefits. Eat an onion every day,<br />

cooked or raw. Onions will help lower cholesterol. They also<br />

have a regulating effect on blood sugar levels, which make<br />

them good for diabetes and hypoglycaemia. Onions are also<br />

good for coughs. Thinly slice a red, brown or white onion,<br />

cover <strong>with</strong> honey and leave overnight. Next day, drink the<br />

syrup.<br />

Pickled onions and other pickled vegetables are usually<br />

high in salt, sugar and other preservatives including nitrates,<br />

which are carcinogenic.<br />

POTATO<br />

Potatoes were brought from the New World to the Old in the<br />

1500s and by 1800 became the most important food in<br />

Ireland. A member of the deadly nightshade family but<br />

generally not a troublemaker, potatoes are the favourite<br />

vegetable in Australia. Potatoes contain vitamin C as well as<br />

potassium. Potatoes are low in calories, it is only when they<br />

touch oil do the calories skyrocket. The skin contains most<br />

of their nutrients but don't eat the skin if it has turned green,

Cutting out the offending green bit is sufficient to remove<br />

the danger.<br />

SPINACH<br />

In Australia we tend to call silver beet, spinach. Silver beet<br />

has a much stronger flavour and bigger leaves than its refined<br />

English counterpart. Both are a good source of iron (the nonhaem<br />

variety) and other nutrients, including chlorophyll.<br />

PUMPKIN<br />

A member of the melon family and native to Central America,<br />

pumpkin is a lovely vegetable, particularly as part of a roast<br />

dinner. The orange flesh provides plenty of beta-carotene, as<br />

well as potassium and soluble fibre.<br />

Pumpkin seeds contain zinc and other factors, including a<br />

phyto-hormone that is useful in the treatment of the prostate<br />

gland.<br />

Grains<br />

Carbohydrates should make up the lion's share of our diet,<br />

anywhere up to 70 per cent. Carbohydrate foods are a mixed<br />

bag: grains, legumes (also a good source of protein), fruit,<br />

vegetables and sugar. Grains, including wheat, rye, barley,<br />

rice, oats, millet and corn are the principal food for the majority<br />

of the world's population. This was not always so.<br />

Anatomy of a grain<br />

The endosperm takes up the majority of the grain. It is<br />

mostly starch and contains soluble fibre, as well as a<br />

few vitamins and minerals. Inside the endosperm lies


TAe Food We Eat 101<br />

the germ, the embryonic plant which, if lefi to its own<br />

devices, would use the endosperm as food to fuel its<br />

growth into a little seedling. The germ contains protein,<br />

fatty acids and is a storehouse of minerals and vitamins,<br />

particularly vitamin E. Protecting the grain is a tough coat<br />

called the husk or bran. This is where we frnd most of<br />

the fibre, including celIulose. The husk also contains a<br />

fair amount of micronutrients, but not as many as the<br />

aleurone layer, the undercoating that lies snugly over the<br />

grain and under the husk. Grains contain a large percentage<br />

of carbohydrate, around 80 per cent. They also<br />

contain a little more than 10 per cent protein and are in<br />

general very low in fat, at about 2 per cent.<br />

Flour power<br />

Grains, also known as cereals, are the seeds of grasses. As<br />

hunters and gatherers thousands of years ago, we gathered<br />

these wild grass seeds, in addition to the roots, leaves,<br />

flowers, fruits, insects and odd rodent that crossed our wandering<br />

path. The wild grasses of yesteryear were very different<br />

from the lush ears of corn and wheat we cultivate today.<br />

It would have been slim pickings indeed. Not only would it<br />

have been time consuming to gather these seeds but they are<br />

virtually inedible in the raw state. So, we would have had to<br />

lug these seeds on our 40 kilometre walk (the estimated daily<br />

average distance covered by our fit ancestors) and at the end<br />

of a long day, grind the pesky seeds on a bit of rock, then<br />

add water, then cook it over the coals. Pass the insects please.<br />

So much less trouble.<br />

Nevertheless, someone was keen to eat their wheaties.<br />

Humankind became 'civilised' when it began to cultivate<br />

grain around 10 000 to 15 000 years ago. Sowing seeds in the


102 The Commonsense Ggide to <strong>Eating</strong> <strong>Well</strong><br />

ground meant that we had to hang around until harvest time.<br />

Houses, villages and cities were a natural progression. For the<br />

first time we could store food, in 'granaries'. This gave us<br />

time for other pursuits like organised religion, literature,<br />

flower arranging and war. People who controlled the grain,<br />

controlled society.<br />

The symbolism of agriculture has deeply permeated<br />

human consciousness. The Greek goddess Demeter was in<br />

charge of the harvest; Egyptians revered Osiris, the god of<br />

agriculture.<br />

White is Aght?<br />

The first grainy foods would have been gruels or porridges<br />

or flat breads: the whole grain broken up <strong>with</strong> primitive<br />

mortar and pestle. Then came rotary stone mills, driven by<br />

water, slave or horsepower. Steel roller milling came <strong>with</strong> the<br />

industrial revolution and this is where the trouble began. Up<br />

until this time, it was very difficult to separate the chaff (bran<br />

and germ) from the rest of the flour. So breads were invariably<br />

wholemeal. When processing technology became widespread,<br />

a more refined, whiter, fluffier bread was achievable<br />

and, for the first time, affordable. The common man enthusiastically<br />

embraced white bread that was formerly reserved<br />

for the toffs on the hill, the upper crust!<br />

Unfortunately, we now know that removing the bran and<br />

the germ also removes a good proportion of fibre and micronutrients<br />

(see the table below). In addition, bleach is added<br />

to make white flour whiter. Check your labels: 'bread-making<br />

flour' means white wheat flour.<br />

Gluten<br />

Gluten is found in several grains, including wheat, rye,<br />

barley and oats. Gluten gives flour strength, biding<br />

quality and elasticity: all desirable qudties in bread,<br />

pasta and pastry making. Coeliac (see-lee-ak) disease is<br />

a condition where gluten causes damage to the Iining of<br />

the intestines. In its most severe form, coeliac affects<br />

1 in 2000 people and is a condition that is oilen inherited.<br />

Although only a tiny proportion of people have<br />

coeliac disease proper, many more people may be<br />

sensitive or slightly intolerant to gluten. Symptoms<br />

often include bloating, flatulence and constipation or<br />

diarrhoea.<br />

WHEAT<br />

Wheat is the most commonly consumed grain in Australia.<br />

On average Australians eat 1.5 kilograms of wheat flour each<br />

week, mostly in the form of bread, breakfast cereals, biscuits<br />

and pasta. There are two main types of wheat: Triticzcm<br />

vaCgare (soft) used for bakery items and breads; and 2". dumm<br />

(hard) used for pastas and crusty Italian-style breads. Nutritionally,<br />

they are very similar but hard wheat contains slightly<br />

more protein. Wheat contains the most gluten of all the


104 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

grains, which helps it rise in baking. Some people are allergic<br />

to the gluten in wheat, others to other parts of the wheat<br />

grain itself.<br />

Wheat does not have to be made into flour, other products<br />

that are wheat based include:<br />

bulgur - here the wheat grain has been debranned, parboiled,<br />

dried and cracked: the crunchy bits found in<br />

tabouleh and kebbeh are bulgur;<br />

semolina - the hard part of durum wheat;<br />

cous cous - processed from semolina; and<br />

matzo meal - flour used to make unleavened bread during<br />

Passover.<br />

RICE<br />

Rice is the staple food for half the world's population. While<br />

people in Bangladesh eat 65 kilograms of rice yearly, Australians<br />

average a measly 5.6 kilograms a person. Rice is a<br />

balancing grain. This doesn't mean you can hold a bowl of<br />

rice on your head and not let it topple, but that rice helps<br />

balance an under- and over-stimulated system. Brown rice is<br />

the whole grain, high in fibre, vitamins and minerals. White<br />

rice has been rumbled by sugar granules to remove the outer<br />

husk, in addition to the aleurone (vitamin and mineral-rich)<br />

layer, while a portion of the germ remains. Converted rice<br />

(Sungold) is steamed and dried before milling, allowing<br />

the aleurone layer to remain and is therefore higher in<br />

micronutrients.<br />

There are hundreds of varieties of rice, including basmati<br />

and jasmine. Nutritionally, they are similar. There is no<br />

gluten in rice. Rice cakes, which look and taste much like<br />

drink coasters, are brown rice that has been heated to 200<br />

degrees Celsius for six seconds.

WILD RICE<br />

Wild rice is not actually a type of rice but a grain in its own<br />

right, <strong>with</strong> the exotic botanical name of Zizania apuatica. Traditionally<br />

gathered by hand in waterways by the North American<br />

Indians, wild rice is high in protein, and can be cooked<br />

together <strong>with</strong> brown rice or other grains. Wild rice does not<br />

contain gluten and is a low-allergy food.<br />

BARLEY<br />

Pliny wrote that Roman gladiators were called 'Hordearii' or<br />

barley eaters, believing that the barley they ate made them<br />

strong. You don't see barley much nowadays except in homemade<br />

soup. The soluble fibre in barley helps lower blood<br />

cholesterol. It is used medicinally because of its anti-inflammatory<br />

and cooling properties. A valuable remedy for the<br />

treatment of the symptoms of cystitis (a bladder inflammation)<br />

is to simmer 50 grams of barley in 1 litre of water for<br />

40 minutes. Strain, add lemon and honey. (Barley water will<br />

help to relieve the discomfort of cystitis but will not get rid<br />

of an infection.)<br />

Pot barley is the whole grain, which is very hairy. Pearl<br />

barley is more commonly used, and has the husk removed.<br />

Roasted barley is used as a coffee substitute, often <strong>with</strong><br />

chicory added.<br />

Barley contains gluten, although not in significant<br />

quantities.<br />

RyE<br />

Rye is a cold-climate grain, which explains its popularity in<br />

northern Europe. Its high water-binding capacity keeps rye<br />

bread moist for longer and increases satiety (sense of fullness).<br />

Rye contains gluten, though not quite as much as<br />

wheat. Most light 'rye' breads contain as little as 30 per cent<br />

rye flour, the rest being white wheat flour. One hundred per


106 The Commonsense Gzlide to <strong>Eating</strong> WeZ.2<br />

cent rye bread is very dark, very heavy and has a distinctive,<br />

earthy flavour. Pumpernickel is a type of bread made <strong>with</strong><br />

whole grains of rye.<br />

In the days before pesticides and fungicides, rye crops<br />

were susceptible to a type of fungus known as black sclerotia<br />

or ergot. <strong>Eating</strong> grain infected by this fungus caused a condition<br />

called St Anthony's Fire. Symptoms included burning<br />

pains in the arms and legs, gangrene, itching and hallucinations.<br />

There have been no reported incidences of St Anthony's<br />

Fire since the 1950s. However, research has shown that<br />

one of the derivatives of ergot is lysergic acid (LSD), which<br />

explains the hallucinations!<br />

OATS<br />

Oats are fed to horses to give them pep and they will do the<br />

same for humans who are down on their pep. Oats are one<br />

of the fattier grains, although by no means high in fat at 8<br />

per cent. The fats are the good, essential fatty acids (see page<br />

52) and are especially good for the skin when taken internally<br />

and externally. Dry skin and eczema will respond well to oats.<br />

To make an oat sock for use in the bath or shower, take one<br />

sockette, fill <strong>with</strong> two handfuls of oats, then tie off the open<br />

end. The slimy, sticky stuff that exudes from the stocking<br />

material is very soothing for the skin and can be used instead<br />

of soap.<br />

Rolled oats are the most common form of eating oats. The<br />

whole grain is simply steamed and flattened. It is worth the<br />

expense to get really good organically grown fresh oats.<br />

Compare them <strong>with</strong> your supermarket version, which can<br />

then be relegated to filling the oat sock.<br />

CORN<br />

Corn is the major grain of Central America and Africa, where<br />

it is called mealie. In Australia, we normally use the fresh


The Food We Eat 107<br />

corn as a vegetable, reserving the dried ground flour for<br />

Mexican dishes like tortillas or in the making of polenta.<br />

Other grains include the following:<br />

Triticale is a hybrid of wheat and rye that was developed in<br />

1964. As a plant it thrives on sandy, low-fertility soils and is<br />

resistant to disease. It is high in protein, but seldom seen.<br />

Triticale contains gluten.<br />

Amaranth was the staple grain of the Aztec people. Cultivation<br />

was banned in 1519 by the invading Spaniards in a<br />

devastating example of economic imperialism.<br />

Millet is still the major grain of northern China. We call it<br />

birdseed. It is quick to cook but fairly bland.<br />

Buckwheat is not, botanically, a grain but for all intents and<br />

purposes is treated as one. A member of the rhubarb and<br />

sorrel family, buckwheat has a distinctive nutty flavour.<br />

Although it does not contain gluten, buckwheat flour is often<br />

used to thicken soups and sauces. In Russia, the whole grain<br />

is cooked, called kasha and eaten as a side dish to the main<br />

meal. A northern European Jewish delicacy are blintz (or<br />

blinis), little pancakes made from buckwheat flour, wrapped<br />

around fruit and cream. The Japanese created soba noodles<br />

from buckwheat flour.<br />

Breakfast cereals<br />

Apart from bread and pastry, the most common form<br />

in which we consume grain is in breakfast cereals. The<br />

first breakfast cereal would have been a humble gruel<br />

or porridge. However, since early this century breakfast<br />

cereals have become crisp, coloured, sugared and<br />

heavily advertised.<br />

W1th the exception of one or two, breakfast cereals<br />

are a waste of time, money and nutritional space. The<br />

majority contain sugar, some as high as 44 per cent.


108 The Commonsense Guide to <strong>Eating</strong> Wet!.<br />

They are mostly made from processed flour that has<br />

been stripped of its rnicronutrients, manufacturers kindly<br />

returning one or two of the many they have removed.<br />

You are much better off having baked beans on<br />

wholemeal toast, egg, sardines or even last night's Ieftovers.<br />

However, things started well in the 1800s, when<br />

nutritional advocate and Seventh Day Adventist, Sylvester<br />

Graham, started to promote the health-giving qualities of<br />

wholemeal flour. (In fact, wholemeal flour was dubbed<br />

Graham flour in his honour.) The first breakfast cereal,<br />

Post Grape Nuts, was created in 1863 and was baked<br />

Graham flour, cracked and served <strong>with</strong> milk. In 1877,<br />

another Seventh Day Adventist, Dr Harvey Kellogg, produced<br />

Granola and in 1902 the fvst corn Bake was born.<br />

Things went downhill from there.<br />

Fruit contains fructose, a simple sugar that is one-and-a-half<br />

times as sweet as glucose. Surprisingly, fructose causes blood<br />

sugar levels to rise more slowly than glucose. For this reason,<br />

fruit can be included in the diets of people <strong>with</strong> blood sugar<br />

problems, including diabetes and hypoglycaemia and makes<br />

a good, between-meal snack.<br />

It is preferable to eat the whole fruit rather than just the<br />

juice of the fruit. For starters, there is more fibre in the whole<br />

fruit, allowing you to feel fuller than just drinking the juice.<br />

Let your hair down and try to eat the seeds, core and skin if<br />

possible.<br />

Eat plenty of fruit, two to three servings a day. Don't,<br />

however, overindulge, and end up like poor Fortunatus, at a<br />

banquet in the first century AD: 'First I was those


The Food We Eat 109<br />

sweet fruits the common people called peaches; they never<br />

tired of serving them to me, and I never tired of eating them;<br />

soon my stomach was distended like that of a woman about<br />

to give birth; I wondered how it was that I could stretch so<br />

far. Thunder growled and rolled <strong>with</strong>in me, wandering in my<br />

entrails. There was great wind.' Fortunatus was the chaplain<br />

to Queen Radegonde of Germany.<br />

Stewing fruit is a forgotten art of winter. Not only does it<br />

make your home smell loved, stewed fruit is calming and an<br />

excellent food for stress. Pears, apples, peaches, apricots and<br />

quinces do very nicely stewed. Half fill a large pot <strong>with</strong> water,<br />

add a few spoonfuls of honey, some cardamon pods, a cinnamon<br />

stick and a few cloves. Wait for the water to reach the<br />

boil, take the pot away from the stove then place your fruit,<br />

cheek by cheek, nearly submerged. Put the lid back on the<br />

pot and let the fruit sit there steaming quietly at excessively<br />

low heat for two or so hours.<br />

Dried fruits are energy packed and make a good snack<br />

food when combined <strong>with</strong> a few raw nuts and seeds.<br />

Unfortunately, fruits are ofien dried <strong>with</strong> sulphur dioxide.<br />

Some people are allergic to sulphur and their symptoms<br />

may include asthma, eczema and in extreme cases, a<br />

nasty closing of the throat. Buy sun-dried fnrits if you<br />

are sulphur sensitive. Another packaging trick is to add<br />

mineral oil to sultanas and raisins to make them look<br />

APPLE<br />

Snow White and William Tell knew about them, even Eve<br />

couldn't resist munching on one. Apples are strewn through


110 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

human history, rich <strong>with</strong> symbolism. When an apple is cut in<br />

half horizontally you can see a five-pointed star, the pentagram,<br />

the geometric shape that sends witches and warlocks<br />

into an esoteric frenzy.<br />

Apples contain pectin, particularly around the core. Pectin<br />

is a soluble fibre that helps restore healthy microflora in the<br />

bowel, as well as removing excess cholesterol from the body.<br />

Apple cider vinegar in hot water is an old Vermont remedy<br />

for arthritis. Dab a bit of neat apple cider vinegar on bites<br />

and stings to reduce itching and inflammation. An oldfashioned<br />

cure for diarrhoea is to grate an apple (green or<br />

red) and eat it after it turns brown.<br />

APRICOT<br />

Apricots are a sunny cousin of the almond, cherry, peach and<br />

plum. Apricots are a good source of potassium, magnesium,<br />

iron and beta-carotene.<br />

AVOCADO<br />

The avocado is actually a fruit but most people think of it as<br />

a vegetable. A native to Central America, the creamy flesh of<br />

the avocado has seduced palates worldwide. Avocados are one<br />

of the few plant foods that contain fat, around 20 per cent.<br />

This is because avocado chooses to store energy as fat, rather<br />

than in the usual form, starch. Don't be put off, the fat in<br />

avocados gives us an opportunity to benefit from the lovely<br />

essential fatty acids, as well as providing us <strong>with</strong> vitamin E.<br />

Avocados are terrific for dry skin problems.<br />

BANANA<br />

Bananas are the favourite of babies and grannies and make a<br />

mean daiquiri too. Did I say daiquiri? I meant smoothie. Full<br />

of potassium, 440 milligrams a pop, bananas are. filling<br />

<strong>with</strong>out being fattening.


The Food We Eat 111<br />

Bananas, particularly those on the green side, are very good<br />

for healing ulcers of the digestive tract, including stomach<br />

ulcers and ulcerative colitis.<br />

BERRIES<br />

Strawberries, raspberries, blueberries, blackberries. The<br />

vibrant colours of berries are due to a group of pigments<br />

called flavonoids, which are potent antioxidants.<br />

CHERRY<br />

Cherries, <strong>with</strong> their beautiful red colouring, are another fruit<br />

<strong>with</strong> plenty of the antioxidant-rich flavonoids, including<br />

anthocyanin. In fact, that's where they get their blue-red<br />

colour from.<br />

DATE<br />

Dates, palms, deserts and desserts go together. Most often<br />

eaten dried, dates are a delicious fruit packed full of fruit<br />

sugar and fibre. Dates satisfy even the hardened sweet tooth.<br />

FIG -<br />

Figs are native to the Middle East (the first tree mentioned<br />

in the Bible) but are equally popular in Greece, Portugal and<br />

Spain. Figs are available fresh or dried, tasting not a bit alike.<br />

Figs are rich in a range of micronutrients, including calcium,<br />

magnesium, iron, copper and manganese. All those little<br />

seedy things in the middle are good fibre.<br />

GRAPEFRUIT<br />

Grapefruits are high in pectin, a soluble fibre, found in the<br />

pithy white bits most of us pick off. Pectin lowers cholesterol<br />

levels and helps remove heavy metals from the body. Grapefruit<br />

is also bitter, making it an excellent tonic for the liver<br />

and gall bladder.


112 The Commonsense Gzlide to <strong>Eating</strong> <strong>Well</strong><br />

GRAPE<br />

Grapes are one of the oldest cultivated fruits. Grape seeds<br />

have been found to have high levels of the flavonoid proanthocyanidin,<br />

which is an antioxidant and is particularly good<br />

for the blood vessels. So stop spitting them out.<br />

LEMON<br />

Lemons contain vitamin C. Their sourness complements liver<br />

function and a substance in lemons called limonene has been<br />

found to be useful in treating gallstones. The juice of half a<br />

lemon in hot water makes a good first-thing-in-the-morning<br />

drink, <strong>with</strong> or <strong>with</strong>out honey.<br />

MANGO<br />

Mangoes are a good source of fibre, vitamin C, potassium and<br />

beta-carotene. No-one has yet found the substance that<br />

makes mangoes addictive, but each summer, hundreds of<br />

thousands of Australians diligently apply their research skills<br />

to this question.<br />

ORANGE<br />

Oranges are a good source of vitamin C, soluble fibre, potassium<br />

and folic acid. Watch the allergy factor. If you have<br />

oranges every single day and have a health problem such as<br />

eczema, cut out the oranges (yes that includes OJ) for a week<br />

or two and see if your symptoms improve. If they don't, then<br />

you're welcome to go back to your oranges. Sometimes the<br />

allergy can be due to preservatives in the orange juice. In<br />

Europe in the nineteenth century, poor children dreamed all<br />

year of receiving an orange for Christmas. It is easy toforget<br />

how lucky we are in Australia, <strong>with</strong> our fantastic range of<br />

produce.

PLUM AND PRUNE<br />

Any dark-coloured fruit (unless they are dark because they<br />

are bruised) is bound to be a good source of the flavonoids.<br />

Plums are no exception. Prunes are dried plums and are the<br />

WATERMELON<br />

Watermelons, as the name implies, are mostly water. They<br />

make a very good tonic for the kidneys and bladder.<br />

.<br />

Milk<br />

Paradise lost<br />

Milk is the perfect food, containing protein, fat, carbohydrate,<br />

vitamins and minerals - all the nutrients mammals (animals<br />

<strong>with</strong> breasts) need to sustain them through babyhood and<br />

early growing years. Unfortunately, for many people milk<br />

causes health problems.<br />

Use it or lose It<br />

Humans are the only mammals who continue to drink milk<br />

after being weaned. Your pussy cat may enjoy (or demand) a<br />

saucer of milk but in the wild, puss wouldn't touch the stuff.<br />

Lactase, the enzyme responsible for digesting milk sugar<br />

(lactose), diminishes at around the time we lose our 'milk<br />

teeth' at five to seven years old. Another enzyme, rennin,<br />

which digests the milk protein casein in the stomach, also<br />

diminishes at this time. Although this is true for the majority<br />

of people, milk-digesting enzymes remain more active in<br />

some races, especially people of Scandinavian origin. Classically,<br />

the case of 'use it or lose it', Nordic folk have a long<br />

history of farming moocows and eating dairy products. Over<br />

trhe generations, their physiology has adapted to a diet that<br />

contains lots of cheese and milk.<br />

Among my patients, I find that if someone has Danish,<br />

Dutch or Swedish blood in their veins, they usually thrive on<br />

milk products, whereas someone of Asian descent should<br />

invariably avoid milk.

What are humans drinking cow's milk for in the first place?<br />

Although we have established that milk is a perfect food, we<br />

need to be clear about whose milk is good for whom. Goat's<br />

milk is perfect for kids; cow's milk is perfect for calves; and<br />

human milk is perfect for human babies. So far, supermarkets<br />

have not seen the marketing potential of selling bottled<br />

human milk.<br />

In terms of infant survival, obviously any milk is better<br />

than no milk. My neighbours rescued a kitten who was<br />

dumped and left to die. Their 14-year-old female Dachshund,<br />

Koo, who had her last litter 10 years ago, started to secrete<br />

milk to feed the kitten. The kitten, Smudge, is flourishing<br />

on Koo's doggy milk!<br />

Here are a few interesting points of comparison between<br />

cow and human milk. First, cow's milk has more than four<br />

times more calcium and protein per millilitre than human<br />

milk. However, more is not necessarily better. A calf doubles<br />

its birth weight in 50 days, whereas babies double their birth<br />

weight in 100 days. Our early development is more skewed<br />

towards nourishing the nervous system rather than bulk.<br />

Second, there are two main types of protein in milk, casein<br />

and whey, which translate into little Miss Muffet's curds and<br />

whey. Cow's milk contains more casein than whey and<br />

human milk contains more whey than casein. People <strong>with</strong><br />

milk allergy tend to be more allergic to casein than whey. It<br />

turns out the balance of essential fatty acids (EFAs) found in<br />

human breast milk is terribly important for the neurological<br />

development of infants. Pre-term babies fed on formula can<br />

become blind and neurologically deficient, and can have<br />

measurable IQ differences.

What's the problem?<br />

With milk there are two possible problems. The first is a milk<br />

sugar (lactose) intolerance; the second a milk protein allergy.<br />

In order to be absorbed, lactose (a disaccharide) needs to<br />

be snipped into two separate units: glucose and galactose.<br />

The enzyme lactase is just the man for the job. If lactase is<br />

not available, lactose cannot be broken down and absorbed<br />

and will continue down the bowel. Water will enter the bowel<br />

to dilute the sugar, causing diarrhoea. In addition, bacteria<br />

will eat the sugar, producing bloating and flatulence. The<br />

symptoms of lactose intolerance are diarrhoea and flatulence.<br />

Ninety-five per cent of Asian people are lactose intolerant,<br />

whereas northern European and Scandinavian races are better<br />

able to tolerate it.<br />

Lactose intolerance is an 'intolerance' to lactose simply<br />

because there are insufficient quantities of the enzyme<br />

lactase to deal <strong>with</strong> it. Milk allergy is a different story. As<br />

previously mentioned, it is the casein in milk that seems to<br />

be the troublemaker. It appears that the immune system of<br />

the sensitive individual will react when a fragment of casein<br />

is absorbed. When the immune system gets involved it is<br />

truly an allergy. The reactions to a milk allergy are not as<br />

immediate as ,that of lactose intolerance. Symptoms fall into<br />

three main groups: skin, mucus and emotional. Skin-related<br />

symptoms are usually eczema or skin rashes. Mucus-related<br />

symptoms can manifest as chronic sinusitis, post-nasal drip<br />

(mucus dripping down the back of the throat) and a constant<br />

stuffed-up nose. Milk allergy also contributes to ongoing<br />

colds, asthma, tonsillitis and glue ear in children. Emotional<br />

symptoms are a lot more difficult to detect.<br />

Addictive allergies<br />

About 10 years ago, a psychologist and nutritionist called<br />

Alexander Schauss researched a group of troubled teenage


The Food We Eat 11 7<br />

boys who were held in detention centres in the United States.<br />

He noticed that all the boys ate a diet very high in milk<br />

products: milk, ice-cream, cheese and chocolate. Schauss took<br />

a number of boys off milk products entirely and found that<br />

<strong>with</strong>in a few weeks their negative and violent behaviour had<br />

changed significantly. On the whole, the boys were calmer<br />

and less angry. This was confirmed by the carers and the boys<br />

themselves. Interestingly, they still craved milk products.<br />

Fascinated by the change, Schauss recorded these results and<br />

developed a theory about addictive allergies.<br />

There are receptor sites in the brain that act like tiny baseball<br />

mitts, which grab a fragment of protein (called endorphins),<br />

like grabbing a baseball. With an addiction, the mitts get desperate<br />

to hold the ball. If there is a shortage of balls - craving<br />

will result. Craving is a sign of physical addiction. The milk<br />

protein fragments, Schauss believes, act in a similar way to the<br />

body's own endorphins, setting up a constant craving for milk<br />

products and mood problems when milk is unavailable.<br />

If milk protein is a problem, avoid yellow cheese, cottage<br />

cheese, ice-cream, whole milk and skim milk (skim milk has<br />

less fat, not less protein).<br />

The olden days: what's changed<br />

Old naturopathic texts recommend raw milk for all sorts of<br />

diseases, including catarrhal or mucus related conditions. Most<br />

modern naturopaths shudder at the thought of milk. Something<br />

must have changed. Pasteurisation has been the law for several<br />

decades (unpasteurised goat's milk is sometimes available).<br />

Pasteurisation, named for Louis Pasteur who confirmed the<br />

presence of disease-causing germs, involves heating milk at<br />

62 degrees Celsius for 30 minutes. This will kill most bugs.<br />

Formerly, milk was frequently infected <strong>with</strong> diseases including<br />

tuberculosis, which could be transmitted throughout the community.<br />

Although there have been no modern studies to my


118 T4e Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

knowledge comparing the difference between pasteurised and<br />

non-pasteurised milk on our health, the intense heating of milk<br />

may change its protein structure, possibly increasing the likelihood<br />

of milk allergy in the sensitive individual.<br />

Another, more recent process is homogenisation, the breaking<br />

up of fat so that fat droplets are evenly distributed<br />

throughout the milk. Cream no longer floats to the surface of<br />

the milk bottle to be a treat for your cat; even the bottle has<br />

gone! Homogenisation increases the rate at which milk goes<br />

off due to the increased surface area of the fat droplets. There<br />

are raised levels of the enzyme xanthine oxidase, which has<br />

been implicated in atherosclerosis.<br />

Antibiotics, pesticides and hormones can all be detected in<br />

milk, due to today's intensive farming techniques, adding to<br />

our chemical burden.<br />

What to do<br />

When it comes to food allergies there appears to be a threshold.<br />

If you are travelling well health-wise, you might be able<br />

to deal <strong>with</strong> one or more servings of milk products but when<br />

the immune system is under challenge, whether it be from<br />

stress or infection, you will not be able to tolerate the same<br />

amount of milk products and they are best avoided at this<br />

time. Get to know the signs from your body. Stay away from<br />

known food allergens, including milk, when you know your<br />

body is under extra stress (see tailor-made for food allergies,<br />

page 205).<br />

Yoghurt<br />

Even if you are sensitive to milk, you may be able to tolerate<br />

small amounts of yoghurt. The bacteria that make yoghurt<br />

feed on the lactose, so already we have reduced one problem.<br />

In addition, the bacteria excrete lactic acid, which changes<br />

the protein structure slightly, so that it presents less of an


The Food We Eat 119<br />

allergic challenge. The best yoghurt to choose is plain, not<br />

flavoured, made <strong>with</strong> acidophilus, bifidus or bulgaricus<br />

bacteria.<br />

Sheep and goat's milk<br />

Still the milk of choice in several European rural communities,<br />

sheep and goat's milk tend not to cause as many allergy<br />

problems as cow's milk (although the lactose levels are the<br />

same). Goat's milk is an acquired taste but the cheese is quite<br />

delicious. Sheep's milk takes less getting used to but is<br />

harder to come by in delis and healthfood shops. However,<br />

the yoghurt is more readily available and is yummy.<br />

Soy milk, dce milk, almond milk<br />

Soy milk has many benefits, not least by providing the phytooestrogens<br />

(see soy, page 124). However, soybeans do not<br />

have breasts. Soy milk, or any other 'milk' derived from a<br />

seed, nut or grain, is not the same as milk from a mammal.<br />

They do provide certain nutrients but should not be considered<br />

as a total food in the same way as animal or human milk.<br />

This is particularly important for babies and young children.<br />

In addition, many people are now becoming allergic to soy<br />

milk if they drink lots of it.<br />

Mtfk and osteoporos~s<br />

Calcium is important for bones and in the prevention of<br />

osteoporosis, a common problem among women and,<br />

increasingly, men in Australia. Calcium is a mineral available<br />

from a variety of foods, not just milk products.<br />

Interestingly, in countries like China, which traditionally<br />

do not have d k in their diet, osteoporosis is not a significant<br />

health problem. The Beijing Osteoporosis Prow<br />

1996 concluded that 'hip fracture rates (usually caused


120 The Commomense Guide to <strong>Eating</strong> <strong>Well</strong><br />

by osteoporosis) in Beijiig are among the lowest in the<br />

world'.<br />

Over- 60 per cent of Australian women consume<br />

less thah the recommended daily amount of calcium.<br />

Although milk is a reliable source there are many other<br />

foods that provide calcium.<br />

The following is a list of non-dairy, calcium-fich foods:<br />

Beans<br />

Legumes, also known as beans or pulses, have been around<br />

gastronomically much longer than grains. Currently, however,<br />

beans are not in favour, which is a great shame as they have<br />

much to offer nutritionally, being low in fat and high in fibre,<br />

protein and micronutrients. Beans have the same calories as<br />

grains but four times the protein. Beans are high in soluble<br />

fibre, which means they help lower cholesterol, reduce the<br />

risk of heart dhease, prevent constipation and stabilise blood<br />

sugar levels.<br />

Quite possibly, the bean's relatively recent fall from grace


The Food We Eat 121<br />

is due to a combination of factors. One is the reduction of<br />

available time for pottering around the kitchen. Beans take<br />

some time to cook. The second reason may be cultural; the<br />

fading of traditional recipes over the generations. Many cuisines<br />

have great bean dishes such as the Greek dip sava, the<br />

Italian lentil soup lenticce and, of course, the Mexican refried<br />

beans.<br />

Beans can be stored for a long time in your cupboard and<br />

retain most of their nutrients during storage and cooking. In<br />

fact, beans have to be cooked. Trypsin inhibitors are on the<br />

outside of legumes. Thought to be the legume's protection<br />

against digestion by birds and other animals, trypsin inhibitors<br />

stop the action of trypsin, a protein-digesting enzyme.<br />

Without trypsin, the bean cannot be properly digested.<br />

Trypsin inhibitors can be broken down by soaking, then<br />

cooking the legume.<br />

Canned beans are a time-saving alternative to soaking and<br />

cooking beans yourself. For example, adding a can of kidney<br />

beans to a little bolognaise sauce increases the fibre, or adding<br />

a can of beans to a vegetable soup lifts the protein content<br />

considerably.<br />

Beans means farts<br />

Beans are accused of causing flatulence. Humans pass<br />

wind 14 times daily, on average 600 milIiIitres of gas,<br />

most of which is swallowed air. The rest comprises 40<br />

per cent carbon dioxide produced by gut bacteria, 10<br />

per cent hydrogen, methane, sulphur and by-products<br />

of bacteria, including skatoles, ammonia and hydrogen<br />

sulphide (rotten egg gas). So where do beans fit in?<br />

Beans contain oligosaccharide - a type of starch that is<br />

resistant to digestion. As the oligosaccharides pass<br />

through the small intestine to the colon, resident bacteria


122 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

will break them down and cause gas. People who are<br />

used to legumes in their diet will, over time, produce<br />

microflora that are less likely to cause the problem of<br />

excess flatulence. So the more beans you eat, the less<br />

flatulence you will have.<br />

ADZUKI BEANS<br />

Also known as red beans, adzuki beans are a favourite in<br />

Japan. This small, round, reddish-brown bean has a light,<br />

nutty, sweet flavour. It is often made into candied bean cakes.<br />

Although it tastes sweet, this bean helps regulate blood sugar<br />

levels. Since the Han Dynasty in China (206 BC to AD 220),<br />

the red bean has meant good luck and so is always included<br />

in any festive meal. Dried beans are put out to ward off evil<br />

spirits at Chinese New Year.<br />

BLACK BEANS<br />

Black beans are used in South American and Caribbean<br />

cooking. They form the basis for the salty, fermented and<br />

yummy Chinese black bean sauce.<br />

BORLOTTI BEANS<br />

Borlotti beans are brown or speckled pink and also travel<br />

under the name Romano. They are native to tropical America<br />

and were introduced to Europe via the Spaniards. In 1528,<br />

some of these beans were sent to Pope Clement VII in Italy,<br />

possibly the first beans in Italy. Borlotti beans are popular in<br />

Italian soups and stews to this day.<br />

BROAD BEANS<br />

Broad beans are also known as fava, and were first cultivated<br />

during the Iron and Bronze ages. They were the staple food


The Food We Eat 123<br />

for the poor in ancient Egypt. In ancient Rome, dry broad<br />

beans were used as counters for voting in Roman elections.<br />

Broad beans can be eaten green and uncooked, however, they<br />

may cause a form of anaemia known as favism in some Mediterranean<br />

people <strong>with</strong> a special sensitivity to a toxin found<br />

in the beans.<br />

CHICKPEAS<br />

Chickpeas or garbanzos are a round, light brown-coloured<br />

bean <strong>with</strong> a chicken-beak point at one end. They are a<br />

favourite throughout the Middle East, India, Spain, Italy and<br />

Greece. Hommos, felafel and besan flour are all chickpea<br />

products. Dry roasted chickpeas flavoured <strong>with</strong> salt, spices<br />

and chilli are a popular snackfood in India.<br />

HARICOT BEANS<br />

These are the common garden variety baked bean or navy<br />

bean. Canned baked beans are a staple food for many single<br />

young men. Haricot beans make a quick, high protein, low<br />

fat breakfast or snack.<br />

KIDNEY BEANS<br />

Kidney beans are best known for their leading role in chilli<br />

con carne and as a support act in three-bean mix.<br />

LENTILS<br />

Lentils are called lentils because their shape resembles the<br />

lens of the eye. Lentils, whether they are red, green or brown,<br />

are big news in India where they form the basis of dhal.<br />

Lentils need no soaking and cook in around 20 minutes.

PEAS<br />

Peas are legumes. We normally eat them fresh or thawed,<br />

reserving the split dried peas for pea and ham soup. The olde<br />

English 'pease pudding' featured split peas.<br />

SOYBEANS<br />

The soybean is native to China, where it has been cultivated<br />

for 13 000 years. It is the most widely grown and utilised<br />

legume and is the biggest cash crop in United States, used<br />

mostly as feed for livestock. Soybeans contain more oil than<br />

most beans; around 17 per cent of the dried bean. But the<br />

fat is good fat, high in the essential fatty acids.<br />

One of the main reasons for soy's popularity (it can't be<br />

the taste), is that soybeans have the highest protein content<br />

of any plant food, exceeding many animal foods.<br />

Soybeans have received a lot of attention because they<br />

contain the isoflavone genistin, a plant substance that is structurally<br />

similar to but much weaker than oestrogen, and is<br />

actually able to bind onto oestrogen receptor sites in the<br />

body. This is a boon for menopausal women who are running<br />

low in their own oestrogen (see tailor-made menopause diet,<br />

page 209). The beauty of phyto-oestrogens is that if you are<br />

making sufficient oestrogen, they won't be adding any more.<br />

Our own oestrogen is stronger by far. Phyto-oestrogens only<br />

make up any shortfall.<br />

Value-added soy<br />

A 'second generation' soy product is tofu or beancurd.<br />

This white, fm (or floppy), custard-like preparation is<br />

as boring as batshit unless dolled up <strong>with</strong> spice or<br />

hidden in a stew or stir-fn( but is very high in protein.<br />

Tofu is made by soaking the soybeans, then draining<br />

them. The beans are then pureed and strained to yield


The Food We Eat<br />

I25<br />

a soybean milk. This is boiled, a coagulant added, then<br />

strained. Tempeh is fermented tofu and is a reliable<br />

source of protein and B12 (good for vegans whose main<br />

source of protein is soy).<br />

Those ghastly sausage-looking things called TVP (textured<br />

vegetable protein) that come in cans are made<br />

from soybeans.<br />

Miso is fermented soy paste made by inoculating<br />

trays of rice <strong>with</strong> the mould Aspergillus oryzae. A ground<br />

preparation of cooked soybeans and salt is then mixed<br />

in and the mass is allowed to ferment for several days<br />

before being ground into a paste that has the consistency<br />

of peanut butter. The entire rniso process takes 10<br />

to 40 days. Miso is used as a fIavouring for soups and<br />

on vegetables. Miso is also nice spread thinly on<br />

wholemeal bread <strong>with</strong> a layer of tahini and sprinkled<br />

sunflower seeds on top. Miso is a source of B 12 as well<br />

as bowel-friendly bacteria.<br />

Sprouts<br />

Sprouts are excellent food. Germination of the seed into<br />

a sprout increases the available nutrients and improves<br />

digestibility. The sight of a few shrivelled alfalfa sprouts<br />

eat them anyway. Sprouting deactivates any trypsin<br />

If you are clever you can sprout your own. Mime<br />

own buy only organic seeds; assume all others have<br />

been sprayed.

Types of sprouts include alfalfa, mung bean, fenugreek<br />

and red clover. Sprouts can be eaten raw or added<br />

to soups and stews.<br />

Meat<br />

There is plenty of evidence humans were born to eat meat.<br />

Look at our canines (teeth, not dogs), meat-stripping stomach<br />

acid, guns and quite a mean streak. Yet we are omnivores, taking<br />

a bet both ways, equipped to handle plant food as well as meat.<br />

Vegetadans, B12, protein and Iron<br />

By combining legumes and grains, vegetarians are less<br />

likely to be protein deficient. The vegetarians most at risk<br />

of deficiencies, especially of B12 and iron, are vegans.<br />

Vegans, oAen inspired by ethical reasons, eat nothing<br />

made from an animal, including miIk products and even<br />

honey. As B12 is made by animals, it is relatively<br />

common for vegans to be low in this vitamin. <strong>Eating</strong><br />

fermented foods such as miso and tempeh (fermented<br />

tofu) is a way of obtaining B12. Taking some vitamin C,<br />

or eating vitamin C-rich food will enhance absorption of<br />

iron from the likes of spinach, parsley and kelp.<br />

BEEF<br />

7<br />

In 1938, the first year of food-consumption statistics, Australians<br />

ate an average of 64 kilograms of beef (including veal)<br />

each. By 1997, we were eating about 39 kilograms a piece -<br />

still quite a lot of cow. The difference in consumption<br />

between the prewar years and now is not that we have turned


into a country of vegetarians but consumption of other meat<br />

has increased, especially chicken and pork.<br />

Beef, like most animal products, is a reliable source of<br />

protein, containing the full spectrum of essential amino acids.<br />

Importantly, beef contains haem iron, the type of iron that is<br />

well absorbed, as opposed to non-haem iron found in vegetables.<br />

Beef contains B vitamins and zinc, a mineral we need<br />

and that is often in short supply. The nutritional down side<br />

to beef is that it contains quite a lot of fat: older cattle more<br />

than yearlings; grain-fed more than those that roam the range.<br />

Beef feedlots are a growing trend in Australia, particularly in<br />

export beef. This practice crowds the cows together in restrictive<br />

feedlots and has been deemed to be cruel by the RSPCA.<br />

LANIB<br />

Lamb contains more fat than beef but is still a terrific source<br />

of protein and iron. Australians eat 11 kilograms of lamb each<br />

per year (1997). Lambs are often born in the bush and for<br />

most of their short lives (less than one year) receive little<br />

intervention from man, until they are killed. Unlike chickens<br />

and pigs, they are free to chew on bits of scrub and are not<br />

routinely given antibiotics or hormones. Lamb is a reasonably<br />

'clean' meat as far as chemicals go, the down side is that there<br />

is more fat by weight than protein.<br />

PORK<br />

Porkers have a tough life, often being confined to small pens.<br />

Pork used to have a bad name because it was likely to be<br />

infected by the parasite trichinosis, but this is no longer a<br />

problem. Pork has quite a following in Australia <strong>with</strong> average<br />

consumption around 18 kilograms each per year. Pork has traditionally<br />

been a high-fat meat, until the use of hormones that<br />

produce leaner pigs - 'low-fat porkers'. We are seeing a lot<br />

more of these technologically enhanced foods. The pigs were

Fish and shellfish<br />

Fish are a good source of protein and generally low in fat.<br />

What fat there is, is the highly prized omega3 variety (see<br />

page 47). The amount of omega3 fatty acids in a few servings<br />

of fish is enough to treat health problems like PMS and<br />

eczema. The fish <strong>with</strong> the highest amount of omega3 fatty<br />

acids include mullet, trout and salmon. Some fish, including<br />

whitebait and sardines, have edible bones, which are an<br />

excellent source of calcium. All in all, fish is a fantastic addition<br />

to the diet. Eat it three to four times a week. Three<br />

servings of fish a week reduce by half the risk of sudden<br />

death by heart attack in those <strong>with</strong> cardiovascular disease.<br />

One problem is that heavy metals like mercury have been<br />

found in the flesh of bigger fish, especially shark (flake).<br />

CRAB, LOBSTER, OYSTERS, MUSSELS, PRAWNS, SCALLOPS<br />

People go bananas over the exotic, subtle flavours of shellfish.<br />

Unfortunately, they are a common allergy food.<br />

We now know that the cholesterol in shellfish is the 'good'<br />

type, meaning that you can eat them <strong>with</strong> abandon, if you<br />

can afford to do so. The only problem <strong>with</strong> shellfish is where<br />

they come from. As they naturally live and feed around estuaries,<br />

they are more likely to be contaminated <strong>with</strong> pollutants<br />

being washed offshore and heavy metals, including aluminium<br />

and mercury.

Coffee<br />

Directly below my clinic is an Italian coffee shop. I often see<br />

patients furtively gulping a cappuccino minutes before their<br />

appointment time <strong>with</strong> me, thinking that coffee and naturopaths<br />

don't mix.<br />

Coffee can be compatible <strong>with</strong> good health. However,<br />

some people are definitely better off <strong>with</strong>out it. Coffee is a<br />

frequently used negotiating tool by me when designing diets.<br />

I'll let you have one cup of coffee a day if you sacrifice the<br />

camembert and chocolate. Mostly, it's a win-win situation.<br />

Coffee is the world's favourite drug and the second most<br />

important export after oil. It has a long history of use in Arabia<br />

and Ethiopia and was sipped in China back in 2000 BC.<br />

Coffee spread to Europe in the fifteenth century and was<br />

used as a medicine and to help keep monks awake during<br />

hours of meditation. Voltaire, the French poet and revolutionary,<br />

was said to drink 50 cups of coffee a day. The highest<br />

consumption I have come across was a merchant banker who<br />

drank 25 cups a day.


132 The Commonsense Guide to <strong>Eating</strong> We!/<br />

Caffeine<br />

There are over 200 chemical constituents in the roasted<br />

coffee bean. Some responsible for its heavenly aroma, others<br />

for flavour. Caffeine (a plant alkaloid known as methyl xanthine)<br />

is probably the most widely studied constituent of<br />

coffee, although there is evidence that many of the actions<br />

of coffee on the body come from chemicals other than caffeine.<br />

Caffeine is present in several other plants, including<br />

tea, mate, kola nut and guarana.<br />

One gram (1000 milligrams) of caffeine can have toxic<br />

effects; 10 grams of pure caffeine is lethal. The average cup<br />

of coffee delivers around 100 milligrams of caffeine and most<br />

people stay <strong>with</strong>in safe limits. However, I have seen sensitive<br />

people have side effects such as insomnia and high blood<br />

pressure from as little as one cup of coffee a day.<br />

Bodily effects<br />

Caffeine is a nervous system stimulant. A couple of<br />

cups can improve attention, concentration and coordination.<br />

More than this can lead to, or exacerbate,<br />

all sorts of problems ranging from insomnia, panic<br />

attacks, headaches, irritability and depression. Watch<br />

for caffeine in cola and other soA drinks. Children<br />

especially, can get hyped up <strong>with</strong> caffeine in their<br />

systems.<br />

Caffeine can increase your heart rate and blood pressure,<br />

although this doesn't appear to be a problem for<br />

long-term coffee drinkers. Some people experience<br />

erratic heartbeat or arrythmia. For people <strong>with</strong> heart<br />

disease, more than a couple of cups a day is not recommended<br />

as caffeine has proven to increase blood<br />

fats - a risk factor in heart disease.<br />

Coffee tastes bitter and like all true herbal bitters,


T&e Food We Eat: But SAozsB We? 133<br />

coffee increases production of gastric and other digestive<br />

juices. This is probably why a cup of coffee is<br />

commonly had after dinner, to aid digestion. As it<br />

powerfully stirs up gastric juices, coffee is to be<br />

avoided by anyone <strong>with</strong> a stomach ulcer, gastritis,<br />

reflux, or tender tummy. For these people particularly<br />

avoid drinking coffee on an empty stomach. Caffeine<br />

relaxes the oesophageal sphincter, increasing the likelihood<br />

of reflux.<br />

Caffeine is a smooth muscle relaxant. Smooth muscle<br />

lines the bowel and blood vessels. For this reason, a<br />

strong cup of coffee may help some headaches or<br />

migraines that are caused by constricted blood<br />

vessels (take care that the headache is not merely a<br />

symptom of caffeine <strong>with</strong>drawal). The other effect is<br />

to relax the bowel. For some people this means a<br />

strong coffee will cause diarrhoea, for others a cup of<br />

coffee is necessary for regular bowel movements. If<br />

coffee helps you to move your bowels, the cause of<br />

your constipation is most likely stress, as you hold<br />

tension in your bowel.<br />

You don't have to have sugar in your coffee to<br />

increase your blood sugar levels. Caffeine stimulates<br />

the release of adrenalin, the buzzy stress hormone.<br />

Adrenalin causes a sudden rush in blood sugar.<br />

Unfortunately, this increase in blood sugar levels<br />

quickly slides into a fall. Those <strong>with</strong> a tendency<br />

towards hypoglycaemia (see page 25) will do best by<br />

avoiding caffeine altogether.<br />

Caffeine is a diuretic, increasing the flow of urine. As<br />

a result, minerals including iron and calcium are<br />

passed out in the urine. Clients often look crestfallen<br />

when I counter their proud claim of fwe cups of water<br />

(in coffee) <strong>with</strong> the fact that they are excreting more


134 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong>'<br />

water than they are drinking. Cruel but fair. Drink a<br />

glass of water to every one cup of coffee.<br />

Pregnant women oAen tend to turn off coffee. Which<br />

is well and good as the unborn baby has a terrible<br />

time of metabolising caffeine. It takes the foetus up<br />

to 140 hours to process what it takes the adult one<br />

hour to do. It is wise to omit coffee when you are<br />

trying to fall pregnant as some studies show that caffeine<br />

reduces fertility (in women) by half. Caffeine is<br />

not only able to cross the placenta but also passes<br />

into breast milk. Cut down the coffee if you have a<br />

fractious breast-fed bubby.<br />

There is a proven link between caffeine and breast<br />

lumps (non-cancerous) and frbroids. It also adds to<br />

premenstrual breast tenderness.<br />

Athletes have been using caffeine to enhance performance<br />

for many years. Robert de Castella used to<br />

drink a cup of coffee before every marathon. Caffeine<br />

has been found to increase (for a short time) muscle<br />

stamina and strength. Due to its effect of increasing<br />

blood fats it makes available a source of fuel for<br />

muscles and saves precious stored glycogen in endurance<br />

events such as a marathon.<br />

The following are some conditions that may well respond<br />

positively to a caffeine-free lifestyle: panic attacks, high blood<br />

pressure, painful periods, fibrocystic breast and uterine<br />

disease, PMS, restless leg syndrome, heart disease, high<br />

cholesterol, diarrhoea, depression, insomnia, hyperactivity,<br />

stomach ulcers, gastritis and gastro-oesophageal reflux.<br />

Most people are able to handle one or two cups of coffee<br />

a day. However, if you have one of the conditions above or


The Food We Eat: Bllt S&ould We2 135<br />

are particularly sensitive to caffeine, then even this small<br />

amount will have negative results.<br />

Caffefne <strong>with</strong>drawal - cold turkey<br />

If you think caffeine may have a negative effect on your<br />

health, the best way to test your theory is to eliminate<br />

caffeine (including tea, cola and chocolate) for one week.<br />

The chemical caffeine does not accumulate in the body<br />

and has a half life (the time taken to reduce the level in<br />

the body to half its initial value) of around four hours.<br />

Peak concentration of caffeine occurs <strong>with</strong>in one hour of<br />

consumption. At around 18 hours aAer your last cup of<br />

coffee, the levels of caffeine are very low and this is the<br />

time to be wary of caffeine <strong>with</strong>drawal. Lock yourself<br />

away for the next 24 to 48 hours. You will probably<br />

experience throbbing headaches, irritab'iltty and extreme<br />

fatigue, which wiIl help you develop the convincing argument<br />

that in order to feel better, all you need Is a cup<br />

of coffee. Don't do it.<br />

Tea<br />

From the tea ceremony in Japan to the Australian tradition<br />

of a cup of tea <strong>with</strong> a lamington, tea has had symbolic and<br />

cultural significance for over 2000 years.<br />

Green tea has risen in popularity since the discovery of its<br />

cancer-protective qualities, mainly due to a tannin called E$igallocatechin<br />

gallate, which helps in liver detoxification and<br />

strengthening the immune system. Black tea also contains<br />

some of these antioxidants, although the fermenting process<br />

which turns green tea into black diminishes the quantity a<br />

little.


136 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

Tea contains a certain amount of caffeine but because of<br />

the tannins less caffeine is absorbed into the body. Some<br />

sensitive individuals will notice a caffeine effect but generally<br />

tea gives you a gentle lift rather than a caffeine kick.<br />

Puffy eyes from a late night respond to a 10 minute,<br />

cool teabag compress. A solution made from weak<br />

black tea sprayed finely over mattresses and pillows<br />

deactivates omnipresent dust mites.<br />

Tea seems to slow down peristalsis, the snaky muscular<br />

movement of the bowel, increasing a tendency towards constipation.<br />

There is some evidence that tea may decrease bile<br />

secretion, thereby hindering fat digestion.<br />

Both tea and coffee reduce our absorption of iron and<br />

calcium from food. Theophylline, the alkaloid in tea, is a<br />

stronger diuretic than coffee, so make sure you drink a glass<br />

of water for every cup of tea.<br />

Alcohol<br />

One for the road<br />

Most of us like a drink or two. A glass of wine or beer marks<br />

the end of a busy day, the celebration of a happy event, part<br />

of a romantic dinner, or a fun night out <strong>with</strong> friends.<br />

Ages ago humans cottoned on to the fact that any fermenting<br />

vegetable or fruit will give us a fine old time. Fermented<br />

grapes turn into wine and brandy; potatoes and grains<br />

into vodka; and rye into rye whisky. Not surprisingly, the<br />

human animal has evolved mechanisms to cope <strong>with</strong> alcohol.<br />

Alcohol is the scientific name of a group of substances that


The Food We Eat: But Shozcrld' We? 237<br />

includes ethanol. Ethanol is the alcohol in alcoholic beverages.<br />

Ethanol is toxic in the smallest amount. Methanol, even<br />

more deadly, is the alcohol in methylated spirits.<br />

Alcohol is soluble in fat and water. This may not sound<br />

like something to write home about, but it is the key to why<br />

alcohol is so deadly. The membranes that line our cells are<br />

made up of a combination of fat (phospholipid) and protein.<br />

Alcohol, because of its fat solubility, is able to enter cells<br />

uninvited causing immediate damage.<br />

While most nutrients wait until they reach the small intestine<br />

before being absorbed, alcohol is impatient, 20 per cent<br />

being absorbed straight from the stomach. This is why we<br />

can feel the effect seconds after the first sip and the reason<br />

why we get drunk faster on an empty stomach. When alcohol<br />

crosses the stomach wall, some hydrochloric acid will seep<br />

across, disturbing the thick mucus lining that normally protects<br />

the stomach wall from damage. Over time, stomach<br />

inflammation (gastritis) and stomach ulcers may occur. These<br />

effects are made worse by drinking alcohol on an empty<br />

stomach - food acts as a buffer.<br />

VIP needs to be shown the door ASAP<br />

After absorption, alcohol is treated as a VIP not because it is<br />

worthy of respect but because it is one toxic individual and<br />

needs to be dealt <strong>with</strong> ASAP. Alcohol increases the risk of<br />

cancer of the oesophagus, stomach, bowel and pancreas. As<br />

well as increasing blood fats and cholesterol levels, it is also<br />

a risk factor in diabetes, impotence and heart disease.<br />

The first by-product of alcohol is acetaldehyde and it is<br />

this creature that is responsible for many of the more unpleasant<br />

sensations of alcohol: facial flushing, headache and<br />

nausea. Behind the scenes, acetaldehyde causes nerve and<br />

brain damage, as well as slowing down liver function. Acetaldehyde<br />

is also the chemical of addiction. We have certain


138 The Commonsense Guide to <strong>Eating</strong> We!'/<br />

receptor sites in the brain, willing and able to receive molecules<br />

of acetaldehyde. The more of these receptor sites, the<br />

more alcohol we desire. There have been some controversial<br />

studies that suggest that alcoholics are born <strong>with</strong> more receptor<br />

sites than non-alcoholics.<br />

Acetaldehyde is the chemical of addiction. Some people<br />

crave the feeling of euphoria it brings. Alcohol is a nervous<br />

system depressant. A few drinks will depress normal inhibitions<br />

and is the reason behind many embarrassing office party<br />

incidents. It also compounds many cases of domestic violence,<br />

child ause and road accident deaths.<br />

Various enzymes are responsible for the conversion of<br />

alcohol into acetaldehyde and indeed, the remaining metabolic<br />

conversions. These enzymes require the assistance of<br />

certain micronutrients including zinc, B1 and B3 in order to<br />

do their duty. If the body is low in any of these nutrients,<br />

alcohol will take longer to be broken down, allowing a longer<br />

time to wreak its damage.<br />

Acetaldehyde is finally broken down into acetyl groups<br />

that can be used for energy but is more often converted into<br />

fat. A gram of alcohol yields seven calories a gram, which is<br />

more than carbohydrate and protein and less than fat. Even<br />

at seven calories a gram, alcohol is not a preferred source of<br />

energy as it causes so much damage and uses up lots of micronutrients<br />

in the bargain.<br />

Cheers: the case for the defence<br />

In defence of the odd grog, there are plenty of healthy octogenarians<br />

who swear by a daily tipple. A glass of wine <strong>with</strong><br />

dinner helps us to unwind. A relaxed digestive system is more<br />

likely to do a good job of digesting dinner. If we are well<br />

nourished, particularly in the micronutrient department, our<br />

body can deal <strong>with</strong> alcohol - just not to excess. The liver


TAe Food We Eat: But Should We.p 139<br />

takes one hour to metabolise 10 grams of alcohol, the equivalent<br />

of a standard drink.<br />

Information arising from the 'French Paradox' research<br />

gives cause for celebration for red wine aficionados. Several<br />

years ago, scrawny, fat-deprived nutritionists became<br />

inflamed <strong>with</strong> indignation when they realised their French<br />

cousins were enjoying escargots literally swimming (do snails<br />

swim?) in olive oil, salads dripping in fragrant dressing and to<br />

top it all off were seen to guzzle litres of Beaujoulais - and<br />

that was just for lunch. After much intensive research into<br />

the wee small hours in quaint Parisian cafes, it was determined<br />

that the bioflavonoids, proanthocyanidins, found in red<br />

grapes are a powerful antioxidant. These bioflavonoids possibly<br />

prevent the onset of heart disease (see bioflavonoids,<br />

page 172).<br />

Chocolate<br />

The Aztecs prized their beloved but unpronounceable cacahuaquchtl<br />

tree, even calling it 'food of the gods'. The invading<br />

Spaniards sent some of the dried cocoa berries home. The<br />

original 'hot chocolate' was born, by brewing up a few beans<br />

together <strong>with</strong> vanilla and a dash of chilli.<br />

Throughout the 1700s chocolate was used medicinally as<br />

a heart tonic, probably due to cocoa's diuretic properties.<br />

(Diuretics are often prescribed for people <strong>with</strong> high blood<br />

pressure to reduce blood volume therefore reducing overall<br />

pressure in the blood vessels.) In addition, chocolate is a<br />

warming food. For people <strong>with</strong> poor circulation who hate<br />

wintertime, hot chocolate made <strong>with</strong> good quality cocoa, hot<br />

water and honey can be quite therapeutic.<br />

Chocolate holds a special place in the hearts, minds<br />

and stomachs of many of us. There is some evidence that


140 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

phenylethylamine (PEA), a chemical found naturally in cocoa<br />

beans, is the reason for chocolate's allure. PEA is an neurotransmitter<br />

that appears to act as an antidepressant and has<br />

been dubbed 'the chemical of love' - which explains the<br />

contradictory behaviour of eating chocolate bars when we feel<br />

fat and unhappy.<br />

Chocolate contains goodish amounts of magnesium, iron,<br />

copper and some B vitamins but don't think of it as a multivitamin<br />

substitute. The down side of chocolate is that it<br />

contains oxalic acid which can be a problem for people <strong>with</strong><br />

a tendency to kidney stones, as oxalic acid readily combines<br />

<strong>with</strong> calcium and most kidney stones are calcium oxalate.<br />

There is a small amount of caffeine in chocolate, and this<br />

should be taken into account if you have any problems <strong>with</strong><br />

caffeine (see page 131). Chocolate can also be an allergy food<br />

for some unfortunate people, particularly those who are<br />

plagued by migraines but also mouth ulcers, heartburn, constipation<br />

and facial swelling. Chocolates are made <strong>with</strong> added<br />

fat, milk and sugar, which makes it a high calorie food.


VITAMINS AND<br />

MINERALS


The basics of<br />

micronutrients<br />

Nowadays, it seems you can't walk past a supermarket or<br />

newsagent <strong>with</strong>out being bombarded <strong>with</strong> information about<br />

vitamins and minerals. Although most of us know that vitamins<br />

and minerals are important, exactly what they do in the<br />

body and why we may need extra is rarely explained.<br />

There are six types of nutrients necessary for good nutrition:<br />

carbohydrates, fat, protein, water and last but not least, vitamins<br />

and minerals. Vitamins and minerals, also known as micro<br />

(small) nutrients, occupy a tiny 5 per cent of our diet, yet they<br />

play a key role in maintaining health. If we are deficient in any<br />

of these micronutrients our well-being will surely suffer.<br />

Vitamins: water soluble and fat soluble<br />

Vitamins are found in plants and animals; they are necessary<br />

for growth and maintenance of health. With few exceptions,


144 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

the body must obtain micronutrients from food or dietary<br />

supplements. Vitamins B2, B9, B12 and K are capable of<br />

being made in the body by our own bowel bacteria, although<br />

often not in sufficient quantities for the body's needs.<br />

There are two categories of vitamins: (1) water soluble,<br />

including vitamin C, B-complex vitamins and the bioflavonoids;<br />

and (2) fat soluble, including vitamins A, D, E and K.<br />

The solubility of a vitamin relates to the way it is absorbed<br />

and transported throughout the body. Water-soluble vitamins<br />

must be consumed daily as they cannot be stored for long<br />

before they are excreted from the body. Fat-soluble vitamins<br />

are absorbed from the small intestine in the same way as fat<br />

in food, <strong>with</strong> the help of bile and fat-metabolising enzymes.<br />

Fat-soluble vitamins may be stored for some time in fat and<br />

liver cells. People who have problems digesting fat or are on<br />

extremely low-fat diets may be at risk of becoming deficient<br />

in these fat-soluble vitamins.<br />

About minerals<br />

Minerals are naturally occurring elements found in the earth's<br />

surface. Minerals coexist <strong>with</strong> vitamins in the body and their<br />

work is interrelated. There are two main groups of minerals:<br />

(1) those we require in larger amounts, including calcium,<br />

magnesium, sodium, potassium and phosphorus; and (2) those<br />

we require in smaller amounts, and these are called the 'trace' '<br />

minerals, including zinc, iron, copper, manganese, chromium,<br />

selenium and iodine.


The basics of micronutrients 145<br />

Are vitamins and minerals a waste of money?<br />

One common misconception is that if vitamins and minerals<br />

are excreted in the urine, this must mean they have not been<br />

used by the body at all and are, in effect, a waste of money.<br />

Vitamin BZ - riboflavin - is a prime offender here, causing<br />

the urine to glow fluorescent yellow. Micronutrients are not<br />

used up, in fact they are recycled, making them very good<br />

value for money. A vitamin or mineral can be used many,<br />

many times as a 'coenzyme', partnering <strong>with</strong> various enzymes<br />

<strong>with</strong>in the body. Without its micronutrient 'partner' the<br />

enzyme is rendered useless. A micronutrient can partner<br />

several enzymes, before being filtered by the kidneys and<br />

excreted into urine.<br />

To supplement or not to supplement?<br />

If I eat reasonably well, do I need to take a supplement? In<br />

an ideal world, where there is no illness, stress, pollution or<br />

processed foods, then the answer to this question would be<br />

'no'. However, for most of us a daily supplement is necessary<br />

to replace nutrients lost in cooking and processing, as well as<br />

those nutrients used up in our battle against stress, cigarettes,<br />

alcohol, pollution and other elements common to modern-day<br />

life. Nutritional supplements are one way to redress this<br />

imbalance.<br />

Where have all our minerals gone?<br />

The soil in which our food is grown is either deficient or<br />

has become deficient in minerals over the years, particularly<br />

potassium, calcium, sulphur, selenium, manganese,<br />

copper, zinc, boron, molybdenum and cobalt.


146 The Commonsense Gzlide to <strong>Eating</strong> <strong>Well</strong><br />

Some medications deplete or interact <strong>with</strong> vitamins in<br />

the body; for example, antibiotics deplete vitamins B1,<br />

B2, B6, B12, C, A, D, K, folic acid, calcium, iron, potassium,<br />

magnesium and zinc. Similarly, the oral contraceptive<br />

pill, cholesterol-lowering drugs and laxatives all<br />

contribute to a depletion of vitamins.<br />

Each cigarette uses up 50 milligrams of vitamin C.<br />

Twenty cigarettes a day uses up 1000 milligrams of<br />

vitamin C, an amount you are unlikely to obtain from<br />

your diet. Cigarettes contain hundreds of different chemicals,<br />

many toxic. The body deals <strong>with</strong> these chemicals<br />

in various ways <strong>with</strong> detoxifl'mg enzymes in the liver<br />

and antioxidants. Both need the help of vitamins and<br />

minerals in their detoxiwng roles.<br />

Heat destroys many vitamins, particularly the B group<br />

and C. Any cooking, particularly overcooked or reheated<br />

foods will have fewer vitamins.<br />

Who will benefit from nutritional<br />

supplementation?<br />

Two groups of people benefit from nutritional supplementation.<br />

The first group use a dietary supplement as 'nutritional<br />

insurance' to prevent illness. These folk are usually<br />

healthy but hectic. They need to ensure 100 per cent efficiency<br />

in their busy lifestyle. A multivitamin <strong>with</strong> an emphasis<br />

on the B group would be perfect for these people. Perhaps<br />

<strong>with</strong> extra garlic and vitamin C to help the immune system<br />

ward off colds and flus.<br />

The second group of people are those <strong>with</strong> a particular<br />

condition that will respond favourably to nutritional therapy.<br />

At these times it is best to consult your practitioner.


The basics of micronutlr'ents 147<br />

How long should you take a supplement?<br />

Like most things worthwhile, natural medicine takes its own<br />

good time. Vitamins, minerals and herbs are not 'quick fixes'.<br />

It takes time, commitment and patience to appreciate the<br />

health benefits natural supplements have to offer. One rule<br />

of thumb is to expect one month of treatment for every year<br />

of an ailment. For instance, if you have had eczema for 15<br />

years then expect the treatment to take as long as 15 months,<br />

although you will probably see results well before then. As<br />

far as 'nutritional insurance' goes, good news is no news!<br />

Nutritional supplementation can help all sorts of conditions.<br />

However, it is most unwise to <strong>with</strong>draw or reduce any<br />

medication for an illness <strong>with</strong>out first seeking advice from a<br />

competent practitioner. Another word of caution: it is easy to<br />

confuse signs and symptoms of one illness <strong>with</strong> another, so<br />

it is advisable to seek an informed diagnosis before commencing<br />

any treatment.<br />

What is the RDI and what does it mean for<br />

you?<br />

The initials RDI stand for the Recommended Dietary Intake,<br />

which is based on the American equivalent RDA (Recommended<br />

Daily Allowance) adapted by the Food and Drug<br />

Administration Board, judged to be sufficient to maintain<br />

health in the average person.<br />

As anyone who has studied statistics (bless them) knows,<br />

population curves peak at the 'average' or 'mean' point and<br />

then taper down either side, from very very below average,<br />

to very very above average. Each one of us is unique. Just as<br />

our nose, eyes and hair colour differ, so too does our internal<br />

biochemistry. Any one of us may have exceedingly high


148 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

biochemical demands for a particular nutrient, say zinc, while<br />

having normal needs for others. In this case, if your diet contained<br />

'normal' RDI quantities of zinc, your body wouldn't<br />

think it sufficient and you may show zinc deficiency signs -<br />

such as poor immune function, delayed skin healing and<br />

menstrual problems or cystic acne - even though your zinc<br />

intake is 'normal'. In addition, certain illnesses or habits like<br />

alcohol or cigarettes may cause a deficiency or a need for<br />

more than 'average' amount of micronutrients.<br />

Mr Average and Mrs Typical<br />

The RDI may be appropriate for Mr and Mrs Average, but<br />

supplements are more appropriate for Mr and Mrs Typical.<br />

A typical person who may benefit from nutritional supplementation<br />

includes anyone who suffers stress, encounters pollution,<br />

is elderly, pregnant or breastfeeding, is an athlete, has<br />

a less than perfect digestive tract, misses meals, eats fast food;<br />

all of which are indications that there is a higher than<br />

'average' need for micronutrients.<br />

When is the best time to take a supplement?<br />

The best time to take supplements is generally <strong>with</strong> a meal<br />

or at the end of a meal. When we eat, all our digestive organs<br />

are revved up, giving the best chance for all nutrients to be<br />

absorbed. The exception to this rule is vitamin C, which can<br />

be taken between meals as well.<br />

If possible, it is preferable to take your vitamins in divided<br />

doses; that is, little and often. This will assist in better absorption.<br />

In reality, many people find this inconvenient and will<br />

forget to take the lunchtime supplement. If this sounds like


The basics of micronzctl$ents 149<br />

you, then it is usually better to take the supplement at one<br />

regular time, say after breakfast. If you are under the care of<br />

a naturopath, he or she may have good reason why you need<br />

to take your herbs or supplements more frequently.<br />

Synergists and antagonists<br />

Most nutrients work best in combination <strong>with</strong> others. This is<br />

the way they are found in nature. For instance, the bioflavonoids<br />

enhance the action of vitamin C and by no coincidence,<br />

bioflavonoids exist together <strong>with</strong> vitamin C in fruit<br />

and vegetables.<br />

Vitamins and minerals are just like people, they have<br />

friends and foes. Micronutrients that assist <strong>with</strong> the absorption<br />

and utilisation of others are called 'synergists'. In the<br />

example above, Vitamin C and the bioflavonoids are synergists.<br />

Micronutrients or other substances that prevent or<br />

hinder absorption and utilisation are called 'antagonists', or<br />

nutrient thieves. Vitamin E and iron are antagonists and if<br />

possible should be taken at either end of the day. Don't worry<br />

if your multivitamin contains both nutrients, you will find it<br />

difficult to remove the E from the tablet! This rule only<br />

applies if you are taking separate tablets of iron and E.<br />

Another rule is when taking a single B vitamin, say B12,<br />

is that you take a B complex as well, as they tend to work as<br />

a team. B12 needs B1, B5, B6, B9 and biotin to be utilised.<br />

Which vitamins should I take?<br />

The Therapeutic Goods Act (TGA) is a mixed blessing for<br />

the health food industry. On the one hand, companies have<br />

had to clean up their act or be tapped on the shoulder by the


150 The Commonsense Gzlide to <strong>Eating</strong> <strong>Well</strong><br />

long finger of the law, There were instances when what was<br />

claimed on the label bore no resemblance to what was in the<br />

bottle. In addition, anyone was allowed to claim that their<br />

product cured anything, from cancer to ingrown toenails. The<br />

guidelines in the TGA make it very difficult to make any<br />

claims. The most a manufacturer can do is to claim temporary<br />

relief of minor symptoms. This causes a great deal of uncertainty<br />

as people mill around the vitamin shelves unsure about<br />

what to take. There is little reliable information around. I<br />

may be accused of beating my own drum but it will be cost<br />

effective and more useful to seek the advice of a good naturopath<br />

who specialises in supplements, to recommend which<br />

supplements you should take and in what quantities.<br />

As far as quality goes, it is best to stick to medium- to<br />

top-of-the-range products. Usually, if manufacturers are<br />

concerned <strong>with</strong> their reputation, they will include quality<br />

ingredients and good formulations. Rather than buying five<br />

or six different vitamins, often there is a formulation which<br />

will suit your needs. For example, women's multivitamins<br />

help <strong>with</strong> menstrual problems, in addition to being a good<br />

all-round multi.<br />

Be nutritionally responsible<br />

Many people find that supplements fill a nutrient gap and<br />

they start to feel a whole lot better. Unfortunately, some<br />

people abuse vitamins and minerals, substituting a pill for a<br />

good diet and lifestyle.<br />

Even when we take a nutritional supplement, we still need<br />

to take responsibility for our health. Good food, rest and<br />

regular hours cannot be provided in a capsule. Supplements<br />

are not a bandaid solution; vitamins and minerals work for us<br />

when we use them wisely.


The basis of micronutrients 151<br />

Here are a few commonsense rules to follow to help<br />

ensure a diet rich in nutrients:<br />

Reduce coffee, tea, cigarettes and alcohol<br />

Eat fresh food instead of canned, frozen or presewed<br />

where possible<br />

Choose wholemeal over refined (white) flour and rice<br />

products<br />

Eat plenty of aII vegetables and fruit<br />

Avoid food and drinks <strong>with</strong> chemicals, preservatives,<br />

artificial sweeteners and colourings<br />

Exercise regularly<br />

Manage your stress<br />

Drink plenty of water

Antioxidants<br />

Just what are antioxidants? And how can they improve your<br />

health now and into the future?<br />

Increased interest in the field of antioxidants has resulted<br />

in fascinating new information. In fact, a revolution has<br />

occurred in the way we view the onset of certain diseases and<br />

even ageing has come under scrutiny. Antioxidants appear to<br />

help prevent or delay these processes.<br />

Free radicals: a necessary evil<br />

To understand why antioxidants are so good, we must first<br />

become acquainted <strong>with</strong> their nemesis - free radicals. A free<br />

radical is defined as any molecule that has an unpaired electron<br />

in its outer orbit. Molecules prefer their electrons paired,<br />

so this situation is disturbing. The free radical molecule <strong>with</strong><br />

the unpaired electron is unbalanced and therefore highly<br />

reactive. In non-technical language, a troublemaker!<br />

Free radicals are formed in the body and have an important


Getting to Know You 153<br />

role to play in energy production, the immune system and<br />

detoxification. We have internal safety mechanisms to deal<br />

<strong>with</strong> them. An excess of free radicals in the system is a<br />

problem, as they tend to form a destructive chain reaction.<br />

The number of free radicals grows as we age. Pollution, pesticides,<br />

radiation, excessive exercise, joint and tissue injuries,<br />

surgery and emotional stress are all capable of increasing free<br />

radicals in the body.<br />

Although they are tiny, free radicals can wreak havoc to<br />

our cells. Free radicals cause harm in two distinct ways. First,<br />

they cause damage to the cell membrane. This means that<br />

nutrients and oxygen cannot enter the cell from the bloodstream<br />

and, conversely, waste products are unable to leave<br />

the cell. This effectively means cell death. Second, free radicals<br />

may also enter the cell and disturb the RNA and DNA,<br />

our cell's genetic material. Mutations will occur when the cell<br />

next divides if free radicals have changed the genetic code.<br />

Free radical damage has been found to be the cause, or promoter<br />

of, diseases such as cancer; heart disease; asthma; autoimmune<br />

conditions like multiple sclerosis and rheumatoid<br />

arthritis; the effects of ageing such as memory loss and<br />

wrinkles; diabetes; and heart disease.<br />

Antioxidants: fighting the good fight<br />

The connection between free radicals and antioxidants is that<br />

antioxidants have the ability to stop free radicals in their tracks.<br />

In fact, antioxidants are often termed 'free radical scavengers'<br />

or 'free radical sinks'. No wonder antioxidants are popular.<br />

They reportedly help delay the rate of ageing and form protection<br />

against various chronic illnesses, as well as ward off the<br />

harmful effects of stress. The antioxidants are either nutrients<br />

or enzymes that require nutrients. Many of these nutrients are<br />

vitamins and minerals we are already familiar <strong>with</strong>, including<br />

vitamins C, E, beta-carotene and selenium.


154 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

Just as the body is capable of making free radicals, so is it<br />

capable of creating antioxidants. ,There are several enzymes,<br />

including catalase and superoxide dismutase, which are antioxidant.<br />

These enzymes require nutrients like copper, selenium,<br />

manganese and zinc in order to function. In addition<br />

to the homemade arsenal, the body imports antioxidants from<br />

food (and supplements) that may be positioned into cell<br />

walls, such as vitamin E, or wander through the body doing<br />

good antioxidant deeds along the way, such as vitamin C and<br />

the bioflavonoids. As research continues into antioxidants<br />

more nutrients are showing their colours, including the catechins<br />

from green tea, anthocyanidins from red wine, lycopene<br />

from tomatoes and substances from bilberry, ginkgo<br />

biloba, St Mary's thistle and rosemary.<br />

Conditions that might benefit from extra antioxidants<br />

Everyone is at risk of free radical damage. A daily vitamin<br />

tablet that focuses on the antioxidant nutrients is highly<br />

recommended. If you have a family history of heart disease<br />

or cancer, take a precautionary antioxidant supplement<br />

regularly.<br />

Food sources of antioxidants<br />

Green, red and orange fruits and vegetables; green tea; red<br />

wine; garlic; and various herbs such as ginko, St Mary's thistle<br />

and bilberry.<br />

The vitamins<br />

Vitamin A<br />

Vitamin A is very important for the eyes. The specialised eye<br />

cells of the retina, rods and cones need vitamin A to function.<br />

Without sufficient vitamin A, the condition known as night


Getting to Know You 155<br />

blindness is likely to occur. The scientific name for vitamin<br />

A is retinol, and our body can store quite a lot of the stuff,<br />

particularly in the liver.<br />

Vitamin A is available only from animal foods, especially<br />

cheese, liver and eggs. This is because animals, including the<br />

human variety, are able to convert beta-carotene, a plant<br />

pigment, into vitamin A. In fact, it is possible to obtain all our<br />

vitamin A requirements from beta-carotene. That is assuming<br />

your digestive system is in spiffing order, as well as having sufficient<br />

quantities of iron and thyroid hormone, which are both<br />

necessary for the conversion of beta-carotene to vitamin A.<br />

In addition to its role in eye health, vitamin A is essential<br />

for the maintenance of epithelia1 cells. Epithelial cells line<br />

the outside and the inside of the body. The skin is a type of<br />

epithelial cell, is too is the lining of the nose, sinuses, throat,<br />

bowel, lungs and vagina. When there is anything that affects<br />

the epithelial cells like an ulcer, irritation from an infection,<br />

or a nasty cough, vitamin A is needed to soothe and heal.<br />

Insufficient vitamin A leads to hardening of the skin, known<br />

as keratinisation, as well as unsightly small bumps (fondly<br />

known as toad skin), especially on the backs of the arms.<br />

Conditions that might benefit fm extra vitamin A<br />

Night blindness, conjunctivitis, sinus, dry skin, dandruff,<br />

asthma, colds, coughs, acne, wrinkles and psoriasis.<br />

Food sources of vitamin A<br />

Cod liver oil, liver (lamb, calf, chicken), butter, fish, cream,<br />

cheese, eggs and chicken.<br />

B-complex vitamins<br />

A family that plays together stays together<br />

There are eight vitamins that are collectively known as the<br />

B complex. The name is not a reference to their personalities,


156 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

but refers to the fact that they work harmoniously together,<br />

as well as being found in similar foods, particularly whole<br />

grains (<strong>with</strong> the exception of B12). The other thing in<br />

common is that they are vital for the release of energy from<br />

the food we eat, and necessary for nerve and muscle function.<br />

The water-soluble nature of the B complex means that<br />

they are excreted, not stored. In essence this means a daily<br />

requirement of all of these vitamins. There is an intricate<br />

balance to the Bs. If you take one to excess, this will lead to<br />

relative deficiencies of the others. Generally, if you need to<br />

take a single B, take a B complex along <strong>with</strong> it. The members<br />

of this happy family are:<br />

B1 Thiamin<br />

B2 Riboflavin<br />

B3 Niacin<br />

B5 Pantothenic acid<br />

B6 Pyridoxine<br />

B9 Folic acid<br />

B 12 Cobdarnin<br />

Biotin<br />

Note: There is no B4, 7, 8, 10 or 11. Substances sometimes<br />

referred to as B vitamins but are not include PABA, B15,<br />

B17 (laetrile), inositol and choline.<br />

Vltamln B1 - thtamln<br />

Vitamin B1, was scientifically recognised in 1926, nearly half<br />

a century before a serious disease called beri-beri was affecting<br />

60 per cent of the Japanese navy. Something lacking in<br />

the Japanese sailors' diet, which consisted almost entirely of<br />

white rice, seemed to be the key. That something turned out<br />

to be thiamin. Thiamin, as many other vitamins, is found in<br />

the husks of grain, which are disposed of in the processing<br />

of white rice and flour. As soon as some ricebran was added


Getting to Know You 157<br />

to their diet, the symptoms of beri-beri, which include paralysis<br />

and nerve dysfunction, disappeared.<br />

B1 is an integral part of the B team, whose job it is to<br />

release energy from the food we eat, including the all-important<br />

glucose, as well as fat and protein. Apart from its teamwork,<br />

B1 is very good for nervy problems. It helps to relieve<br />

anxiety, depression and trembling, particularly the feeling of<br />

'shaking inside'. A rather unusual sign that one might need<br />

extra B1 is a tenderness in the calf muscle, particularly when<br />

pressed.<br />

Alcohol tends to deplete our B1 stores and it is very<br />

common for heavy alcohol drinkers to suffer B1 deficiency,<br />

in extreme cases causing Wernicke Korsakoff syndrome,<br />

which sounds rather more romantic than it is. Symptoms<br />

include mental confusion, paralysis of the eye muscles and<br />

unsteady gait. Tea and coffee are also offenders by reducing<br />

thiamin activity.<br />

Conditions that might benefit from extra B1<br />

Heavy drinking; anxiety attacks; sore calves (particularly<br />

when prodded); tingling or shaking sensations.<br />

Food sources of BI<br />

Brewer's and torula yeast, wheatgerm, sunflower seeds, ricebran,<br />

pinenuts, legumes, whole grains.<br />

Vitamin B2 - riboflavin<br />

Vitamin B2 is the reason why your wee turns bright yellow<br />

seemingly minutes after you take a vitamin pill. The flavin<br />

in riboflavin comes from the Latin word for yellow - flavus.<br />

B2 is another important vitamin in the creation of energy<br />

from the major nutrients glucose, fat and protein. It is also<br />

essential in the maintenance and growth of the epithelial


158 The Commonsense Gtlide to <strong>Eating</strong> <strong>Well</strong><br />

cells, those that cover the body (skin) and line the hollow<br />

structures of the body like the bowel and lungs.<br />

Some of the signs that B2 is low include redness and soreness<br />

at the corner of the mouth, or a red and swollen tongue.<br />

Other signs affecting the skin include eczema, particularly of<br />

the eyelids and along the line from the edges of the nose to<br />

the mouth. An itchiness of the conjunctiva of the eyes may<br />

also be telling.<br />

Conditions that might benefit from extra BZ<br />

Eye irritations, dermatitis, ulcers of the digestive tract, including<br />

mouth ulcers and stomach ulcers. As the oral contraceptive<br />

pill interferes <strong>with</strong> B2 absorption, it would be a good<br />

policy to take a B complex if you are on the pill.<br />

Food sources of BZ<br />

Milk, yoghurt, ricotta, brewer's and torula yeast, chicken,<br />

almonds, wheatgerm, mushrooms and millet.<br />

Vitamin B3 - niacin<br />

Pellagra is the disease indicating the diet is severely lacking<br />

B3. Symptoms of pellagra are well known by medical students<br />

as there is a cute way of remembering them called the<br />

four Ds; that is, dermatitis, diarrhoea, dementia and death.<br />

While most people do not progress to the extremes of the<br />

latter two Ds, B3 can be of benefit to several health problems.<br />

Another piece of evidence that our body's biochemistry is<br />

remarkable is that the amino acid tryptophan can be converted<br />

into B3, <strong>with</strong> the help of B2 and B6. It takes 60 milligrams<br />

of tryptophan to make l milligram of niacin, so it is<br />

not an economical way of procuring B3.<br />

Vitamin B3 is a member of the distinguished team of vitamins<br />

that allow us to obtain energy from glucose, fat and


Getting to Kptow You 159<br />

protein. B3 comes in two forms - nicotinic acid and nicotinamide;<br />

both are used by the body. Nicotinic acid has an effect<br />

on the circulation by widening the blood vessels and increasing<br />

blood flow to the fingers and toes. If you take a reasonably<br />

large dose of nicotinic acid, you will most likely<br />

experience a sudden flush of heat and look like a tomato for<br />

a few minutes. In small amounts, say under 30 milligrams,<br />

this dramatic reaction does not occur and when it does, it is<br />

only transitory. Nicotinic acid has proven to be very useful<br />

in the treatment of heart disease. It is capable of lowering<br />

blood fats (triglycerides), as well as cholesterol. The blood<br />

vessel widening (vasodilating) properties means that it<br />

improves the circulation of blood through the body, helping<br />

to lower blood pressure. It would be wise to seek a competent<br />

practitioner who will help determine the correct dosage when<br />

treating heart disease. Other circulatory difficulties that also<br />

benefit from nicotinic acid include chilblains, cold feet and<br />

hands, Raynaud's syndrome, tinnitus (if the tinnitus is due to<br />

poor circulation) and the type of migraine which has constricted<br />

blood vessels in the head.<br />

People suffering from dermatitis, an itchy red skin condition,<br />

will do well to supplement <strong>with</strong> B3. Nicotinic acid, along<br />

<strong>with</strong> the mineral chromium, is an important component of<br />

Glucose Tolerance Factor (GTF). GTF encourages insulin to<br />

pass glucose from the bloodstream into cells. A controversial<br />

use of B3 has been in the treatment of schizophrenia. There<br />

has been some success in treating the debilitating mental disturbances,<br />

including paranoia, of this disease.<br />

Conditions that might benefit from extra B3<br />

Dermatitis, high blood pressure, high cholesterol, chilblains,<br />

tinnitus, poor circulation, Raynaud's syndrome, migraine,<br />

arthritis, diarrhoea, schizophrenia, sugar cravings, diabetes<br />

and hypoglycaemia.

V%tamln B5 - pantothenlc add<br />

Vitamin B5 has the distinction of being part of the structure<br />

of the opening ambit of the Krebs cycle, a creature called<br />

coenzyme A or CoA to its friends. This may not sound like<br />

a big deal, but not having CoA is like losing the keys to your<br />

car when you are stuck in the middle of nowheresville <strong>with</strong><br />

no water, food or mobile phone. That one little silver key<br />

(<strong>with</strong> the plastic bit on the end) could save your life. CoA<br />

begins the Krebs cycle, the most important energy-producing<br />

cycle we have.<br />

Without sufficient B5 we will start to feel very fatigued<br />

and depressed and all sorts of other things begin to go wrong.<br />

For instance, CoA is also needed to make fatty acids in the<br />

body. More than just fat, fatty acids are the precursors to all<br />

sorts of compounds including the sex hormones, bile and the<br />

stress hormone cortisol. Being deficient in B5 means not<br />

being able to cope <strong>with</strong> stress. Many people find that by<br />

supplementing <strong>with</strong> B5, their feelings of stress diminish and<br />

they feel increased energy.<br />

The beauty boffins caught on to B5 long ago when it was .<br />

revealed that it had an anti-greying and even an anti-ageing<br />

role. It is often included in shampoos and other cosmetics.<br />

Conditions that might benefit from extra B5<br />

Stress, tiredness or depression. B5 is also recommended for<br />

people who are reducing their dosage of cortisone. Cortisone<br />

replaces the body's output of its own stress hormone, cortisol.<br />

By increasing B5 levels, more cortisol can be made.


Food sources of B5<br />

Elderberries, royal jelly, brewer's and torula yeast, liver, egg<br />

yolk and peanuts. Pantothenic acid is derived from the<br />

ancient Greek word pantos, meaning everywhere, which<br />

reflects B5's wide distribution in all foods, and all parts of<br />

the body.<br />

Vitamin B6 - pyridoxine<br />

Like most of her siblings, this little B vitamin is needed for<br />

many enzyme reactions. One group of reactions that B6 is<br />

particularly called for is in the amino acid department. When<br />

certain amino acids need to be transformed into other amino<br />

acids, B6-containing enzymes are called for. Also, when<br />

certain amino acids are authorised to become nerve messengers<br />

(neurotransmitters) such as tryptophan to serotonin, tyrosine<br />

to dopamine, B6 is again on duty.<br />

Vitamin B6 aids in keeping body fluids balanced. When<br />

there is water retention (oedema), B6 can help. Premenstrual<br />

women who have sore, swollen breasts and for one week<br />

every month feel like a beached dugong <strong>with</strong> a bad attitude<br />

will find B6 a godsend. Take 250 milligrams of B6, in combination<br />

<strong>with</strong> a B complex, twice daily about 10 days prior to<br />

the first day of the period.<br />

Another enzyme B6 helps along is delta-6-desaturase, known<br />

to the 'in crowd' as D6D. This little fella is in part responsible<br />

for the conversion of a group of substances called the prostaglandins.<br />

The reason why omega-6 and omega-3 fatty acids are<br />

so popular in treatments is that they are able to convert to prostaglandins<br />

<strong>with</strong> the help of D6D. So, if D6D needs vitamin B6<br />

to work, then B6 it should be given, in bucket loads!<br />

Conditions that might benefit from extra B6<br />

Fluid retention, PMS, carpal tunnel syndrome (especially in<br />

pregnancy), pins and needles, nervous tension and irritability.

Food sources of B6<br />

Torula and brewer's yeast, sunflower seeds, linseeds, walnuts,<br />

whole wheat, tuna, soybeans and beef.<br />

B9 - folk acid<br />

Vitamin B9 is more commonly known as folic acid, which is<br />

the same as folate, its official name. The word folate originates<br />

from the Latin word folkm or leaf, because researchers<br />

first isolated folic acid from spinach and other leafy greens.<br />

Folic acid is well known for its role in preventing babies<br />

being born <strong>with</strong> spina bifida and other neural tube disorders.<br />

Folic acid is necessary for the synthesis of nucleic acids, the<br />

genetic material of cells. If the genetic material is not 100<br />

per cent then all sorts of problems ensue when cells replicate.<br />

In fact, any cell division and creation of protein (the structural<br />

bits of the body) is doomed if there is insufficient folate. This<br />

is particularly so for rapidly dividing cells as found in the<br />

unborn baby, the cells of the gastrointestinal tract and the<br />

skin.<br />

Cancer cells also tend to replicate quickly. Many of the<br />

chemotherapy drugs (used in cancer treatment) are aimed at<br />

blocking B9, to slow the growth of cancer cells. Common<br />

side-effects of chemotherapy include hair loss and digestive<br />

problems, due to the effect on hair follicles and gastrointestinal<br />

cells, which also replicate quickly.<br />

Along <strong>with</strong> B12, folic acid is required for the production of<br />

haemoglobin, the oxygen-carrying bit of red blood cells.<br />

Conditions that might benefit from extra folic acid<br />

Pregnancy and pre-conception, breastfeeding, diarrhoea,<br />

ulcers, cervical cell dysplasia, poor healing and gout. Do not<br />

take large doses of folic acid if you are undergoing<br />

chemotherapy.


Getting to Know You 163<br />

Food sources of folk acid<br />

Brewer's yeast, black eye peas, brown rice, soy, whole wheat,<br />

lentils, kidney beans, broccoli, brussels sprouts, spinach,<br />

cabbage, green beans, walnuts and beef.<br />

Vitamin B12 - cobalarnin<br />

Vitamin B12 is physically the biggest vitamin, that is because<br />

it is the only vitamin to contain a mineral in its structure.<br />

The mineral is cobalt, and that is how B12 arrived at its official<br />

name of cobalamin.<br />

Pernicious anaemia is due to B12 deficiency. B12 is needed<br />

in the creation of haemoglobin, the oxygen carrier of red<br />

blood cells. When there is not enough B12, the red blood<br />

cells become enlarged. A deficiency of B12 will leave you<br />

feeling tired and run down. This is in part due to the lack of<br />

oxygen, as well as the fact that B12 is needed for DNA synthesis.<br />

DNA is the genetic material needed for the normal<br />

growth of cells.<br />

Vitamin B12 is one tricky customer when it comes to<br />

absorption. No matter how much B12 we swallow, in pills or<br />

in our food, it will not be absorbed unless there is something<br />

called Intrinsic Factor (IF) present in the stomach. Certain<br />

glands in the stomach lining (parietal cells) are responsible<br />

for making IF.<br />

Vitamin B12 can only be made by animals, including tiny<br />

animals such as bacteria and perhaps algae. Mushrooms and<br />

other vegetables do not contain B12. If any B12 is present it<br />

can only come from bacterial contamination from an animal<br />

source such as manure. An interesting study on a group of<br />

Indian vegans showed that although their diet was very strict,<br />

that is, included no animal products at all, they obtained some<br />

B12 from vegetables that had not been thoroughly washed of<br />

dirt. The dirt contained bacteria that was a source of B12.

Conditions that might benefit from extra BIZ<br />

Pernicious anaemia (BIZ, folic acid and iron should be given<br />

together in the treatment of anaemia); exhaustion; anything<br />

that effects the digestive system, such as surgery to digestive<br />

system or digestive disorders - for example, ulcer, digestive<br />

tract parasites. Vegans - people who eat no animal products -<br />

are at particular risk of B12 deficiency.<br />

Food sources of BIZ<br />

Liver, shellfish, fish, lamb, beef, eggs and cheese.<br />

Beta-carotene<br />

Bugs Bunny was on to a good thing. Beta-carotene, a yellowyorange<br />

pigment, named because of its carroty origins, is also<br />

known as provitamin A. Even green vegetables contain betacarotene,<br />

but darker pigments, including the bioflavonoids,<br />

can overshadow the orange. There are several carotenes in<br />

addition to the beta variety, although it is predominantly<br />

beta-carotene that is able to be converted to vitamin A. This<br />

happens in the intestines of animals, so you won't find<br />

vitamin A in plants.<br />

Vitamin A can be stored in the body. For this reason there<br />

is a chance of overdoing this very fine vitamin. Unlike A,<br />

beta-carotene cannot be stored for any length of time. Taking<br />

large doses of beta-carotene will not cause any health problems.<br />

The only symptom of excessive use is to turn the skin<br />

a little yellow (carotenodermia) and this will fade over time.<br />

Other carotenes include the likes of lycopene found in<br />

tomatoes, which has proven to be of use in preventing prostate<br />

cancer, and lutein and capsanthin found in red capsicum<br />

and paprika. Beta-carotene, in its own right, has been shown<br />

to be a potent antioxidant.


Getting to Know You 165<br />

Conditions that might benefit from extra beta-carotene<br />

Cancer, prostate cancer and asthma; any condition which<br />

could be benefited by vitamin A.<br />

Food sources of beta-carotene<br />

Red chillies, carrots, fresh and dried apricots, sweet potatoes,<br />

parsley, spinach, pumpkin, mangoes, rockmelon and broccoli.<br />

Biotin<br />

Biotin is often included in the B-complex group. It is a<br />

sulphur-containing vitamin that can be made in sufficient<br />

quantities by the bacteria in our bowel, the microflora. Biotin<br />

is involved in the synthesis of a few amino acids, particularly<br />

those required for skin, hair and nails, which is why biotin is<br />

recognised as a beauty vitamin.<br />

Conditions that might benefit from extra biotin<br />

Baldness, skin problems (including cradle cap in babies) and<br />

dermatitis.<br />

Food sources of biotin<br />

Brewer's yeast, liver, soy, brown rice, egg yolk, peanuts,<br />

walnuts, oats, sardines and almonds.<br />

Vitamin C - ascorbic acid<br />

Have you ever wondered what you have in common <strong>with</strong> a<br />

guineapig - besides feeling like one of life's little experiments?<br />

We are unable to make our own vitamin C, a skill<br />

that dogs, cats and even chipmunks have. Vitamin C, chemically<br />

known as ascorbic acid, can be made from a glucose<br />

molecule, given the correct enzymes. It seems when enzymes<br />

were distributed, guineapigs and humans, as well as other<br />

primates, bats, insects and fish, missed out. As vitamin C is<br />

a vitamin of importance, we have to depend on dietary


166 The Commonsense Gaide to <strong>Eating</strong> We![<br />

sources of vitamin C to fulfil our requirements. Unfortunately,<br />

this is often inadequate for our needs.<br />

Vitamin C is one of the most researched vitamins - and<br />

for good reason, as it has so many roles fundamental to our<br />

well-being. Vitamin C is one of the things you would choose<br />

to take <strong>with</strong> you on a desert island along <strong>with</strong> a good book<br />

and a movie star/model/dog of your dreams.<br />

Scurvy is the famous vitamin C deficiency disease and the<br />

most pronounced symptom of scurvy is, literally, falling apart<br />

at the seams. This is because vitamin C is needed for collagen,<br />

the material integral to muscle, blood vessels and bone.<br />

Without sufficient vitamin C, blood vessels become very<br />

fragile, leaking blood into the surrounding tissues causing<br />

massive bruising. You don't have to get to the total breakdown<br />

level of scurvy to be a victim to vitamin C deficiency.<br />

Those who bruise easily, find that wounds take a long time<br />

to heal or need to recuperate after surgery will all benefit<br />

from extra vitamin C.<br />

Vitamin C is one of the most important antioxidants in<br />

the body. It prevents free radical damage in the watery<br />

components of the body, <strong>with</strong>in and outside cells. The fatsoluble<br />

antioxidant nutrients, such as vitamin E, are responsible<br />

for protection in the non-aqueous places. Vitamin C<br />

protects the body against cigarette smoke and pollution.<br />

Smokers need an extra 50 milligrams of vitamin C for each<br />

cigarette. Vitamin C is also important for the detoxification<br />

mechanisms in the liver, so it would be helpful to take extra<br />

C if you have been exposed to any toxins, including pesticides<br />

or alcohol.<br />

Vitamin C is quite a strong antihistamine and anti-inflammatory.<br />

I can remember having a very nasty hayfever attack on<br />

a bushwalk around Jagungal (near Mount Kosciuszko) - a few<br />

grams of vitamin C completely restored my nose to sanity.<br />

Iron is better absorbed when there is vitamin C present.


Getting to Know You 167<br />

Another feature role vitamin C plays is that of stimulating<br />

and supporting the immune system. Vitamin C has been<br />

shown to increase white blood cell activity and increase resistance<br />

to bacterial, fungal and viral agents. The only sign of<br />

overdoing Vitamin C is diarrhoea.<br />

Conditions that might benefit from extra vitamin C<br />

Recovering from surgery and wounds, easy bruising, lots of<br />

infectious diseases (including colds and flus), stress, exposure<br />

to toxins, hayfever, asthma and allergies, cancer, high cholesterol,<br />

smoking.<br />

Food sources of vitamin C<br />

Acerola cherries, chilli, guavas, parsley, capsicum, broccoli,<br />

brussels sprouts, kiwifruit, strawberries, spinach, oranges,<br />

lemons, grapefruit, mangoes and tomatoes. The Australian<br />

Kakadu plum is the world's richest source of vitamin C.<br />

Chollne<br />

Choline is another vitamin that we can produce in the bowel,<br />

although only about 15 per cent of our requirements are made<br />

in this way and we need to obtain the rest from the diet or<br />

supplements.<br />

Choline is needed to form one of the major neurotransmitters<br />

(nerve messenger), acetylcholine. We would fall down<br />

in a heap if there was no acetylcholine.<br />

Choline is closely associated <strong>with</strong> another nutrient, inositol,<br />

in the formation of lecithin. Lecithin is a structural part of<br />

every cell membrane. It is also a component of the fat-transport<br />

vehicles in the bloodstream, the lipoproteins.<br />

Lecithin, because it is both water soluble and fat soluble,<br />

makes an excellent medium to help in the digestion and<br />

excretion of fats. In fact, this technique is what bile relies<br />

upon when emulsifying fats in the gastrointestinal tract. The


168 TAe Commonsense Guide to <strong>Eating</strong> WeZZ<br />

liver makes bile, and lecithin (or choline) is often given if<br />

there is a diminishment in bile activity.<br />

Conditions that might benefit from extra choline<br />

Gallstones, liver problems, problems digesting fat, high cholesterol<br />

and multiple sclerosis.<br />

Food sources of choline<br />

Lecithin, eggs, soybeans, liver, peanuts, sesame seeds, brazil<br />

nuts, legumes and whole grains.<br />

Vitamin D - cholecalcirferol<br />

The study of vitamins is comparatively new and the classification<br />

of vitamins has been slapdash at best. Vitamin D is<br />

actually a hormone masquerading as a vitamin. By the time<br />

it was found out that vitamin D has more in common <strong>with</strong><br />

hormones than vitamins, the damage was done. Too expensive<br />

to change the stationery.<br />

The main function of vitamin D is to help calcium be<br />

incorporated into bone, giving bone the rock-hardness it<br />

needs. Given enough sunshine, we can make vitamin D very<br />

easily. Sunlight acts on cholesterol on the skin's surface and<br />

is transformed into cholecalciferol, aka vitamin D. Vitamin D<br />

has been dubbed the 'sunshine vitamin' for this reason. It<br />

takes only a few minutes every few days for enough vitamin<br />

D to be formed. In Australia, <strong>with</strong> its obscenely sunny<br />

climate, vitamin D deficiency is rare. The classic deficiency<br />

disease is rickets, epitomised by poor British kids sent down<br />

the mines not seeing sunshine for days and weeks at a time<br />

and ending up somewhat short in stature <strong>with</strong> bandy legs.<br />

Other people at risk are those who live in year-Iong dull climates,<br />

people who wear lots of clothing (some traditional<br />

women in the Middle East) and rarely go outside (some<br />

elderly people). Sunscreen inhibits vitamin D synthesis.


Getting to Know You 169<br />

Make sure you leave a bit of skin sunscreen free.<br />

Vitamin D can also be obtained in the diet. Basically, if<br />

someone else has made vitamin D, we can vicariously<br />

consume it. Vitamin D is found in fish, eggs and milk.<br />

Conditions that might benefit from extra vitamin D<br />

Osteoporosis, osteomalacia, Paget's disease, pregnancy, lactation<br />

and rickets.<br />

Food sources of vitamin D<br />

Cod liver oil, canned sardines, salmon, tuna, butter, liver,<br />

eggs and cheese.<br />

Vitamin E - tocopherol<br />

Vitamin E has been added to beauty creams since the 1950s,<br />

and still is. It is an important antioxidant, and can be found<br />

squeezed into cell membranes to prevent them from being<br />

damaged through oxidation.<br />

Vitamin E used to be referred to as the 'fertility' vitamin<br />

and indeed it is essential for animal reproduction and fertility.<br />

In addition, vitamin E appears to play a role as hormonal<br />

modulator, helping in all sorts of conditions where errant hormones<br />

are involved. Menopausal problems such as hot<br />

flushes, endometriosis and PMS, in particular, can be helped<br />

by vitamin E supplementation. During menopause, an<br />

uncomfortable symptom can be a dry vagina: squeeze the<br />

contents of a 500 iu vitamin E capsule into the vagina each<br />

night.<br />

Vitamin E improves oxygenation of tissues including<br />

muscles. For this reason it is part of many athlete's nutritional<br />

programs as it has shown to enhance athletic performance.<br />

Many people simply feel more energetic when taking vitamin<br />

E. It is also very good for circulatory problems, improving<br />

blood flow all over the body. Especially if the blood is a little


170 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

sluggish, vitamin E has been proven to decrease platelet<br />

aggregation, a cause of clots and a risk factor for heart disease.<br />

Many people feel the benefits of improved circulation, from<br />

cold hands and feet, to chilblains and even gangrene.<br />

Vitamin E applied topically will help the skin to heal, particularly<br />

when scars are present. You can buy creams <strong>with</strong><br />

vitamin E added, or pierce a vitamin E capsule and apply the<br />

oil directly. First make sure the wound has healed and is dry<br />

before adding vitamin E. Aloe Vera, calendula and tea-tree<br />

oil may be helpful in this first stage when the wound is not<br />

dry-<br />

Conditions that might benefit from extra vitamin E<br />

Diabetes (sufferers often have poor circulation), wrinkles,<br />

PMS, menopause, endometriosis, scars, dry skin, cataracts,<br />

Food sowces of vitamin E<br />

Wheatgerm oil, sunflower seeds, cold-pressed safflower oil,<br />

almonds, sesame seeds, sesame oil, olive oil and raw peanuts.<br />

Inositol<br />

Inositol can be produced in the liver as well as being available<br />

in food. Inositol acts together <strong>with</strong> choline as part of the<br />

structure of cell membranes. Interestingly, inositol is also<br />

important in stimulating peristalsis, the muscular wave-like<br />

movement that occurs down the length of the bowel.<br />

Conditions that might benefit from extra inositol<br />

Constipation, skin disorders including eczema, high cholesterol,<br />

fatty liver and multiple sclerosis.<br />

Food sources of inositol<br />

Lecithin, whole grains, legumes, brewer's yeast and molasses.

Vitamin K - phylloquinone<br />

Had vitamin K been born a girl, her name would have been<br />

Gertrude Henrietta or something requiring a deed poll. As it<br />

is, vitamin Ks proper name is phylloquinone. The 'K' bit originated<br />

from the Nobel prize-winning Danish scientist, Henrik<br />

Dam, who started the whole thing by calling it koagulationvitamin.<br />

Let's stick to simple vitamin K.<br />

Vitamin K is needed to make prothrombin, a substance<br />

that helps the blood to clot. If the blood is unable to clot, we<br />

would bleed to death. Although the disease haemophilia is<br />

not due to a vitamin K deficiency, the deadly results are the<br />

same. Newborns are routinely given an injection of vitamin<br />

K to ensure this clotting factor is present.<br />

Although it is important that our blood can form clots, the<br />

down side is excess clotting, the cause of some strokes, heart<br />

attacks and other serious conditions. As our very own gut<br />

bacteria can produce vitamin K and it is available in food,<br />

particularly vegetables, vitamin K is rarely recommended in<br />

supplement form because of the risk of clotting.<br />

Conditions that might benefit from extra vitamin K (not necessariZy<br />

Prolonged menstruation, post-partum haemorrhage, newborn<br />

haemorrhagic disease, bruising and recurrent nosebleeds.<br />

PABA<br />

Para-aminobenzoic acid, PABA for short, is not actually a<br />

vitamin in its own right, but is a component of folic acid. By<br />

A few years ago PABA had a brief stint as a sunscreen

Bioflavonoids<br />

Until recently, bioflavonoids were bundled together and<br />

collectively known as vitamin P, put on the back shelf and<br />

ignored. However, amazing new information about the therapeutic<br />

value of these formerly neglected substances have<br />

come to light. Ain't science grand?<br />

Four thousand different types of bioflavonoids have been<br />

isolated, although only 10 or 12 have been extensively<br />

examined. Bioflavonoids (also known as simply flavonoids)<br />

are red, blue and yellow coloured pigments of plants. The<br />

reddish rust colouring in our rivers comes from the tannins<br />

released from fallen gum leaves. Tannins are bioflavonoids.<br />

The intense blue of blueberries and cornflowers comes from<br />

anthocyanidin, another bioflavonoid. Bioflavonoids not only<br />

provide us <strong>with</strong> colour, they also have a potent effect on our<br />

physiology.<br />

The following are the names of a few bioflavonoids and<br />

where they can be found in nature:<br />

Gtfus fmNfs<br />

Buckwheat


Catechin<br />

Cournarin<br />

Quercetin<br />

Green tea, grapeseeds<br />

Soybeans, sprouts<br />

Citrus peel, onions<br />

Blueberries, cherries, red grapes<br />

Wme, tea<br />

Soybeans<br />

Although each bioflavonoid has it own speciality, they all<br />

have some things in common. For instance, they are excellent<br />

antioxidants. Some outdo the already inspiring vitamins E<br />

and C, exceeding their antioxidant potency by up to 50 times.<br />

Antioxidants are useful in the fight against cancer, heart<br />

disease and in supporting the immune system.<br />

Bioflavonoids are believed to explain the reason behind<br />

the 'French Paradox', the discrepancy in France where they<br />

have a high-fat, high-alcohol diet and very low incidence of<br />

heart disease; hence the 'paradox'. It is thought to be the<br />

bioflavonoids found in red wine - proanthocyanidins - which<br />

provide protection against heart disease. Other bioflavonoids,<br />

such as quercetin and catechin found in a variety of fruits and<br />

vegetables, probably play a supporting role in this paradox.<br />

As mentioned previously, in the early days, bioflavonoids<br />

were called vitamin P. The P referred to blood vessel permeability.<br />

The bioflavonoids (rutin and quercetin in particular)<br />

are very good at reducing the permeability of blood vessel<br />

walls and strengthening them. Conditions where this is useful<br />

include varicose veins, easy bruising, haemorrhoids and after<br />

injury or surgery. The bioflavonoids are also anti-inflammatory,<br />

which makes them useful for after-injury support, arthritis,<br />

as well as any illness of an allergic nature, including<br />

asthma, hayfever and sinusitis.

The minerals<br />

Boron<br />

Boron must be a borin' mineral (sorry), because not much<br />

research has been done on its role in the body. Only a speck<br />

of boron is needed to increase calcium uptake into bone. For<br />

this reason, it has been included in some supplements for<br />

women at risk of osteoporosis. There is some evidence that<br />

boron can help <strong>with</strong> arthritis.<br />

Conditions that might benefit from extra boron<br />

CaIcfum<br />

Calcium is the pop-star of the mineral world, grabbing all the<br />

attention in the print and film media. However, there is no<br />

smoke <strong>with</strong>out fire and calcium has claims to importance.<br />

Calcium is the most abundant mineral of the body, weighing<br />

in at about 2 per cent of body weight. Most of it is found


Getting to Know You 175<br />

in bones and teeth but it is also necessary for other things,<br />

including the smooth workings of muscles and nerves. It<br />

helps to release muscle spasms and frazzled nerves.<br />

One of the most easily absorbed forms of calcium is osteoapatite,<br />

derived from bone (mostly other animals'). Unfortunately,<br />

lead is also stored in bone and you don't want to be<br />

eating any extra lead if you can avoid it. If you can obtain<br />

the bones of some happy animal raised far away from roads<br />

and pollution, you may eat their bones (makes you want to<br />

be a vegetarian doesn't it?). Apart from munching on a femur,<br />

a good way to release the calcium from bones is to make a<br />

stew or soup using meat and bones, such as lamb shank casserole<br />

or old-fashioned chicken soup.<br />

Times of greatest needs for calcium are times of greatest<br />

growth: during pregnancy, lactation, childhood and teenagerhood<br />

around the time they sprout.<br />

A word about milk. Milk and milk products are a reliable<br />

source of calcium, there is no doubt about that. However, for<br />

a variety of reasons, some people's digestive systems do not<br />

tolerate milk well (see page 114) and these people need to<br />

take special notice of non-dairy, calcium-rich foods (see list<br />

on page 120) or take a supplement. If you are slightly intolerant<br />

to milk, you may find small amounts of yoghurt will be<br />

suitable, or perhaps goat's or sheep's milk products.<br />

Fcactors decreasing calcium absorpion<br />

Too much phosphorus decreases the amount of calcium we<br />

are able to absorb. Phosphorus is found in red meat and carbonated<br />

soft drinks (including fizzy mineral water). Alcohol,<br />

coffee and tea also decrease calcium in the body. Cortisone<br />

drugs deplete the body's stores of calcium also. Most people<br />

on long-term cortisone (for arthritis, pain and so on) will be<br />

on calcium supplements.


176 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

Conditions that migk benefit from extra calcium<br />

Osteoporosis, pregnancy, muscle spasms, high blood pressure,<br />

anxiety (especially together <strong>with</strong> insomnia), people on cortisone<br />

drugs and painful periods.<br />

Peri- and post-menopause is a time when extra calcium<br />

may be required. Oestrogen helps keep calcium in the bones.<br />

Menopause means a depletion of oestrogen production, so<br />

this is a time you need to keep your eye on bone density, as<br />

osteoporosis is much more likely at this time. It may be<br />

worthwhile to have a bone density check.<br />

Food sources of calcium<br />

Cheese, milk, bone meal, carob, kelp, oats, parsley, broccoli,<br />

Chromium<br />

Chromium is another one of the minerals that we need in<br />

tiny amounts but if we don't have enough it makes life<br />

awkward, in fact, a non-event.<br />

Chromium stars in the area of glucose processing - the<br />

most valuable energy molecule we know. In order for glucose<br />

to enter cells where it can be converted into energy, the<br />

hormone insulin is needed. Perched on the cell membrane is<br />

Food sources of chromium<br />

Chromium is good stuff, but don't start munching on your<br />

chrome bumper bar yet. There are different forms of chromium<br />

and the type in metal plating, cement, rubber, pollution<br />

and photographics is not the type to ingest. Food that<br />

contains the 'good' chromium includes brewer's yeast, torula<br />

yeast, liver, whole grains and pepper.<br />

Copper<br />

When talking mineral supplements, copper doesn't usually<br />

spring to mind. However, as time passes research keeps<br />

coming up <strong>with</strong> interesting information about its role. For<br />

instance, copper is required in the formation of haemoglobin,<br />

the iron-containing, oxygen-carrying molecule. In fact, copper<br />

assists iron absorption. Copper also helps in the assimilation<br />

of calcium into bone, so it is quite a helpful adjunct to the<br />

treatment of osteoporosis.<br />

Remember when copper bracelets were a hip fashion statement?<br />

As a remedy for arthritis, absorbing the copper from<br />

jewellery via the skin might have some basis - copper is<br />

required for the antioxidant enzyme, superoxide dismutase,<br />

to help stop free radical damage and is also necessary for<br />

collagen synthesis. It is also a component of the pigment<br />

melanin, necessary for skin and hair colour. Apparently<br />

copper also dictates hair curliness, which conflicts <strong>with</strong> the<br />

historic notion of sandwich crusts causing curls.<br />

Oysters, brazil nuts, soy, lecithin, almonds, dry split peas,<br />

mushrooms, chocolate and cocoa.

Fluorine<br />

Fluorine is one hot potato of a mineral. Over the years there<br />

have been many tears and fisticuffs about the question of<br />

fluoridating community water supplies. (A note on definitions:<br />

fluorine is the codger featured in the periodic table as<br />

a yellow gas travelling under the moniker 'F', fluoride is the<br />

biologically active form of fluorine.)<br />

Fluoride plays a role in helping keep calcium in place in<br />

bones and teeth. In bones, it is found in the form of calcium<br />

fluoride, not in the form sodium fluoride, which is added to<br />

our water. Fluoride appears to prevent dental cavities in<br />

growing teeth. It has most effect topically; that is, in direct<br />

contact <strong>with</strong> teeth or in young children when the teeth have<br />

not yet erupted. A mottling or discolouration of teeth, called<br />

dental fluorosis, is common among young peopIe growing up<br />

<strong>with</strong> fluoridated water. There is little evidence that drinking<br />

fluoridated water assists adult teeth. Of more concern is the<br />

theory that is steadily gaining strength that an excess of fluoride<br />

(particularly sodium fluoride) over a period of time can lead to<br />

arthritis-like symptoms and even osteoporosis. Adding sodium<br />

fluoride to the drinking water continues in Australia, New<br />

Zealand and parts of America although it has been banned in<br />

Japan, Scandinavia and most of Europe.<br />

Conditions that migAt benefit from extra fluoride<br />

As fluoride is added to our water supply and as a consequence<br />

is also in processed foods that use water, generally no-one<br />

needs extra fluoride. However, the supplement calcium fluoride,<br />

which is given in tiny doses (Calc fluor) may help in<br />

conditions showing a weakness of connective tissues such as<br />

varicose veins and haemorrhoids.

Iron<br />

Everyone knows about iron, but no-one seems to get enough<br />

of the stuff. Over 40 per cent of Australian women simply do<br />

not eat enough iron for their needs. Signs you are deficient<br />

in iron include looking pale, feeling weak and dizzy, cold<br />

hands and feet, a lack of energy, irritability and cravings for<br />

weird things like dirt and ice (called pica). Of course, not<br />

everyone who is tired is iron deficient, known as anaemic.<br />

Before you hoe into an iron supplement ask your doctor if<br />

she thinks you need an iron test, which is a simple blood test.<br />

One of the reasons iron is so important is that it is part of a<br />

compound called haemoglobin, which is found in all red blood<br />

cells; in fact, it is responsible for the red colour of red blood<br />

cells. Haemoglobin is partly protein, partly iron and it is this<br />

molecule that is capable of holding onto oxygen, the very<br />

oxygen necessary for our survival. With less iron there is less<br />

haemoglobin; <strong>with</strong> less haemoglobin there is less oxygen available<br />

to all the cells of the body, including the brain. No wonder<br />

you feel tired! The brain cannot function properly, nor can<br />

muscles. You feel physically and mentally drained.<br />

Although iron is so vital, we don't want too much of the stuff<br />

on board, as it can oxidise - literally rust - and cause free radical<br />

damage to cells. Our body accommodates this by being very<br />

thrifty <strong>with</strong> iron. As the iron-containing red blood cells die<br />

(every 120 days) the iron is recycled. We also have a vat of iron<br />

stored for an anaemic day, this is called haemosiderin.<br />

Although red blood cells need iron for haemoglobin, there<br />

are other nutrients necessary for the formation of haemoglobin<br />

and the red blood cell itself, These include B9, B12,<br />

B5, B6 and B13 (orotic acid). If there is a deficiency of one


180 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

of these nutrients, this will also cause anaemia. As there is<br />

such a thing as too much iron, it is doubly important that you<br />

get tested for iron deficiency first, as your symptoms could<br />

well be due to a deficiency of these vitamins, particularly B9<br />

and B12.<br />

Iron is one of the most difficult minerals to absorb. We<br />

absorb as little as 10 per cent of the iron we eat depending<br />

on our needs, the type of iron and the state of our digestive<br />

system. The most easily absorbed iron is known as 'haem<br />

iron', which comes from animals. Not surprisingly, we are<br />

better able to absorb a molecule that is similar to our homemade<br />

haem. Haem iron is higher in red meat such as beef<br />

and lamb and lower in fish and poultry. There is very little<br />

iron in milk, cheese and eggs. Vegetables such as spinach,<br />

parsley and kelp contain heaps of iron, but unfortunately the<br />

iron is in the less absorbable non-haem form.<br />

For peak iron absorption our digestive tract needs to be in<br />

tip-top form. Iron in the non-haem form (vegetables, grains<br />

and so on) is better absorbed if there is some acid around.<br />

Stomach acid will do nicely, however, many people have low<br />

stomach acid levels. Other kinds of acid, particularly ascorbic<br />

acid, aka vitamin C, will boost iron absorption. So adding a<br />

few drops of lemon juice to your salad dressing, or drinking<br />

a glass of orange juice <strong>with</strong> your morning cereal has some<br />

merit.<br />

A few things in the diet interfere <strong>with</strong> iron absorption,<br />

especially tea and coffee - don't drink them while you are<br />

eating iron-rich foods. Another item which inhibits the<br />

optimum absorption or iron are phytates. Phytates are substances<br />

found in high-fibre foods, including grains and<br />

legumes (see page 32). Phytates are only a problem if you are<br />

a raw-fibre freak, adding cups of bran to your diet. Phytates<br />

are destroyed by heat, so cooked grains (like bread and porridge)<br />

and beans are fine.

Iron szcpplements<br />

From time to time some people need to take an iron supplement.<br />

As iron is such a tricky customer due to its poor absorption,<br />

it is important to take a supplement that is well absorbed<br />

but causes no problems. The most commonly prescribed iron<br />

supplement is iron sulphate. This is absorbed very well<br />

indeed, but unfortunately side-effects such as constipation,<br />

nausea and stomach cramps are very common. A happy compromise<br />

is iron attached to protein, called iron aminoate. This<br />

is fairly similar in structure to haem iron, the one favoured<br />

by the body.<br />

Conditions that might benefit from extra iron<br />

Heavy periods, pregnancy, endurance athletics (particularly<br />

joggers where the constant jarring destroys red blood cells),<br />

bowel disorders (malabsorption or ulceration where the iron<br />

is either not absorbed at all or lost in the stool), excessive<br />

bleeding.<br />

Food sources of iron<br />

Kelp, red meat, molasses, liver, wheatgerm, wheat bran,<br />

parsley, oysters, sunflower seeds, dried prunes and spinach.<br />

Iodine<br />

Iodine is part of the thyroid hormone thyroxine. The thyroid<br />

is the gland located at the base of the neck; it regulates our<br />

metabolic rate. If it is over- or under-functioning, the thyroid<br />

gland can swell up into a goitre. The thyroid hormones regulate<br />

how much energy the body makes, or doesn't make; and<br />

maintains female and male fertility and libido among other<br />

things.<br />

Signs of being low in iodine include sluggishness, weight<br />

gain, constipation, loss of libido, irregular menstruation,<br />

goitre, loss of hair and brittle nails.


182 The Comonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

There are certain geographical areas where the soil is deficient<br />

in iodine, including the Himalayas and the Hunter<br />

Valley in New South Wales, glamorously called 'goitre belts'<br />

as more people develop goitres who live in these areas. You<br />

don't see too much of this nowadays, as most salt has iodine<br />

added, that is, 'iodised salt'.<br />

Iodine protects against radiation toxicity. After Chernobyl,<br />

the shops were bought out of seaweed, a rich source of iodine.<br />

Conditions that might benefit from extra iodine<br />

Overweight, low metabolism, radiotherapy treatment.<br />

People <strong>with</strong> the symptoms of low thyroid function, as outlined<br />

above, may benefit from eating foods rich in iodine,<br />

particularly a seaweed supplement. Do not take iodine as an<br />

extra supplement unless prescribed by your physician as you<br />

could cause an imbalance in thyroid function.<br />

Food sources of iodine .<br />

Iodised salt, kelp, seaweed, clams, oysters and fish.<br />

Potassium<br />

Potassium is necessary for regulation of our pH or acid<br />

balance and for the proper functioning of nerves and muscles.<br />

Potassium and sodium have an intense relationship: mostly<br />

they act opposite one another in the body. Too much sodium<br />

causes too little potassium, rarely is it the other way around.<br />

Potassium is particularly helpful for the heart, where there<br />

are palpitations, and even high blood pressure.<br />

Conditions that might benefit from extra potmsium<br />

Weak heart, weak muscles, nervous disposition and palpitations.<br />

People taking certain drugs, including diuretics, often<br />

need to be on extra potassium.


Gemkg to Know You 183<br />

Food sources of potassium<br />

Avocados, bananas, asparagus, tomatoes, kelp, molasses, cocoa<br />

powder, soybeans, dried apricots, sunflower seeds, prunes,<br />

lentils, almonds and parsley.<br />

Magnesium<br />

Magnesium has a hectic work and social schedule. Responsible<br />

for over 300 enzyme reactions in the body, magnesium<br />

also finds the time to assist other vitamins and minerals, such<br />

as vitamins C and E, the 3 complex as well as calcium, phosphorus,<br />

sodium and potassium.<br />

In practice, magnesium is invaluable in helping to relieve<br />

stiff muscles and muscle cramps. Magnesium helps relax all<br />

muscles including skeletal muscles, the heart muscle and the<br />

bowel wall and blood vessels, which are both smooth muscle.<br />

Excellent for problems ranging from painful period cramps,<br />

stiff neck and back, to high blood pressure and even constipation.<br />

Magnesium is vital in the production of energy. It is<br />

the central molecule in chlorophyll, the compound in plants<br />

that traps the energy from sunlight.<br />

Conditions t/tat mig4t benefit from extra magnesium<br />

High blood pressure, menstrual cramps, irritable bowel syndrome,<br />

anxiety, muscle weakness, leg cramps, kidney stones,<br />

tremors.<br />

Food sources of magnesium<br />

Whole grains, green vegetables, soybeans, seafood, figs, corn,<br />

apples, peaches and apricots.<br />

Manganese<br />

There is only about 20 milligrams (the size of a small pill)<br />

worth of manganese in the average 70 kilogram person. Nevertheless,<br />

manganese is a vital trace mineral. It forms part of


184 The Commonsense Gde<br />

to <strong>Eating</strong> <strong>Well</strong><br />

an antioxidant complex, as well as playing a very important<br />

role in the formation of cartilage. For both these reasons,<br />

manganese is particularly useful as an adjunct in the treatment<br />

of arthritis.<br />

Tinnitus is a ringing sound in the ears that sufferers find<br />

maddening. Even more maddening is that no-one seems to<br />

know the cause, or a cure. Manganese is necessary for the<br />

formation of tiny little calcium rocks called otiliths, which<br />

help us <strong>with</strong> our hearing and sense of balance. Some people<br />

have found that taking a supplement containing manganese<br />

has helped improve their tinnitus. Just an idea.<br />

Manganese also plays a part in helping to stabilise glucose<br />

levels in the bloodstream, hence its use in diabetes, hypoglycaemia<br />

and sugar cravings.<br />

Conditions that might benefit from extra manganese<br />

Diabetes, sugar craving, hypoglycaemia, arthritis and tinnitus.<br />

Food sources of manganese<br />

Tea, rice bran, wheat bran, pecans, brazil nuts, almonds, oats,<br />

rye, barley, alfalfa, cloves and ginger.<br />

Molybdenum<br />

Not much is known or spoken about molybdenum, probably<br />

due to its unpronounceability. It appears as a coenzyme for<br />

several antioxidant enzymes. It is likely that more information<br />

on the importance of molybdenum will come to light<br />

in the near future. Rather interestingly, it seems to decrease<br />

a sensitivity to sulphates. Some people are intolerant of<br />

sulphur compounds, which are often found as food additives<br />

in wine, beer and dried fruit.<br />

Sodlum<br />

Sodium has been branded as the bad guy of the mineral<br />

world - which is kind of strange considering if we don't have<br />

sodium we die. We normally associate sodium <strong>with</strong> table salt,<br />

which is actually a combination of sodium and chloride. For<br />

the purists, a salt is a compound that can form a crystal made<br />

out of an acid and a base, sodium chloride being one example.<br />

Salt was once expensive, whereas now it as cheap as chips.<br />

The word 'salary' is derived from salt and was the payment<br />

made by the ancient Romans to their soldiers. The proverbs<br />

'salt of the earth' and 'not worth your salt' reveal salt's abiding<br />

value. The primal slimists believe we originated in the sea<br />

and our body chemistry reflects these beginnings. This could<br />

explain why the number of people <strong>with</strong> a salty tooth equals<br />

those <strong>with</strong> a sweet tooth. The kidney preferentially holds on<br />

to sodium, allowing other minerals to be excreted in sodium's<br />

stead.<br />

Sodium keeps fluid in the body, between the cells and<br />

swimming in blood vessels. Along <strong>with</strong> potassium, it maintains<br />

our pH or acid base balance as well as giving permission<br />

for certain substances to enter and leave cells. The primary<br />

digestive fluid of the stomach - hydrochloric acid - requires<br />

sodium.<br />

The main reason sodium has been vilified has been the<br />

association between high blood pressure and sodium. High<br />

blood pressure is one of the risk factors for a heart attack. As<br />

sodium is preferentially retained by the kidneys, more water<br />

is retained in the body, thereby increasing blood volume and<br />

hence blood pressure. However, a sizeable study of 10 000


186 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

people by the British Medical Journal revealed that not everybody<br />

responds in this way. There is even some talk of the<br />

chloride content of salt being to blame. It is pretty rare to<br />

need extra salt, and we should avoid processed, salted foods.<br />

Conditions that might benefit from extra sodium<br />

Diarrhoea and vomiting, which can leave the body depleted<br />

of many minerals, especially sodium; lots and lots of sweating,<br />

although it is better to replace <strong>with</strong> several salts, not just<br />

sodium; severe and prolonged stress can cause the adrenal<br />

glands, which live on top of the kidneys, to cause the kidneys<br />

to lose excess salt. Listen to your body if you have salt cravings<br />

during periods of stress.<br />

Food sources of sodium<br />

Salt, soy sauce, processed meats, yellow cheese, breakfast<br />

cereals, vegemite, marmite, olives and celery. Few people<br />

need to add table salt to their food. There are some 'natural<br />

health salts' available that contain a variety of other minerals,<br />

including some of the more unusual trace elements. If your<br />

diet is mainly free of processed foods, adding some of this<br />

sea salt is okay.<br />

Nickel<br />

In general we are better advised to avoid nickel than to seek<br />

it out. Nickel, however, tends to seek us out as it is a common<br />

by-product of many industrial processes, car exhaust, heating<br />

fuel and cigarettes. Some people are overly sensitive to<br />

nickel, which is present in jewellery. The most common reaction<br />

is an eczema-like rash.<br />

Enough said about the nasty side of nickel, we do in fact<br />

need nickel in small amounts. It appears to be important for<br />

our nuclear material, DNA and RNA, as well as featuring in<br />

several enzymes.


Getting to Know You 187<br />

Conditions that might bendit from extra nickel<br />

It is highly unlikely that people would require nickel supplements;<br />

we tend to get more than we require due to the nickel<br />

in our polluted environment. High levels of nickel may be<br />

associated <strong>with</strong> an increased risk of cancer and heart disease,<br />

headache, nausea and vomiting. One way of detecting excess<br />

nickel is by means of hair analysis, which is a specialised<br />

method of detecting mineral toxicity.<br />

Food sources of nickel<br />

Soybeans, beans, grains, walnuts and hazelnuts. Other sources<br />

include stainless steel cookware, auto exhaust, coal and oil<br />

burners, margarine and detergent.<br />

Sulphur<br />

Sulphur (also spelt sulfur) who signs off as 'S' is responsible<br />

for the pungent smell of eggs, burnt hair (if you have ever<br />

singed your eyebrows while barbecueing a snag you'll recognise<br />

the. smell), the stench you'd expect around hellfire and<br />

brimstone (the archaic name for sulphur) and the air around<br />

the hot volcanic mudsprings of Rotorua. Maybe 'S' stands for<br />

'smelly'. Smell aside, sulphur is reputed to be the beauty<br />

mineral, giving shine to hair and strength to nails. Horses that<br />

are fed sulphur-rich molasses have magnificent glossy coats.<br />

Sulphur sneaks into our diet bound to other items. It is an<br />

important element in three amino acids: methionine, cysteine<br />

and taurine. Protein foods high in these sulphur-containing<br />

amino acids include eggs, nuts and beans. All three amino<br />

acids are used in the detoxifying systems of the body, helping<br />

to remove and inactivate free radicals and other toxins. Garlic<br />

is well known as a detoxifier, in part due to its high sulphur<br />

content. The detoxifying compounds need sulphur to work.<br />

Sulphur itself is antibacterial and antifungal, which led to


188 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

its use in revolutionising medicine as part of the early sulphonamide<br />

antibiotics in the 1930s. These antibiotics have<br />

now been superseded as the generations of bacteria have<br />

become more and more resistant to medication.<br />

Sulphur helps form a type of tissue called glyco-proteins.<br />

These include cartilage, tendons and ligaments - the strong,<br />

stringy, spongy tissue that protects and holds together joints.<br />

It is often this tissue that becomes damaged in arthritis.<br />

The down side of sulphur is that some people can be sensitive<br />

to it, particularly when it is in the form of sulphite or<br />

sulphur dioxide. Asthma-like reactions are most common in<br />

those who are sensitive, as there are sulphite sensitive receptors<br />

in the mouth that can cause spasm of the bronchial tubes.<br />

Skin rashes are another common side-effect. If you fall in this<br />

group, foods to beware of include dried apricots (and all<br />

sulphur-dried fruits), beer, champagne, wine, pickled onions<br />

and cordials. The additive code numbers to watch for are 220,<br />

221, 222, 223 and 224. The sulphur-containing antibiotics<br />

(mentioned previously) may also cause a reaction in the sensitive<br />

individual.<br />

Conditions that might benefit from extra su&hur<br />

Liver problems, including hepatitis; an overload of chemicals<br />

or toxins (the liver needing help to detoxify); limp, lacklustre<br />

hair; and arthritis sufferers.<br />

Food sources of su&hur<br />

Meat, eggs, onions, garlic, cabbage, brussels sprouts, beans,<br />

sesame seeds, brazil nuts and molasses.<br />

Selenium<br />

Selenium is intimately involved <strong>with</strong> an antioxidant called<br />

glutathione peroxidase. Without selenium, this antioxidant is<br />

rendered powerless. Some researchers believe selenium is a


Getting to Know You 189<br />

key nutrient in preventing cancer, atherosclerosis and poor<br />

immune function. Selenium is also effective as an adjunct to<br />

the treatment of dandruff and psoriasis: it is available to use<br />

topically in some shampoo formulations. Similar to iodine,<br />

selenium is protective against the damage of radiation.<br />

Although selenium is freely available as a supplement in<br />

other countries, at this point in time you will need a prescription<br />

to obtain selenium in Australia.<br />

Conditions that might benefit from extra selenium<br />

Poor immune response; cancer; dandruff; psoriasis; heart<br />

disease; and radiotherapy treatment.<br />

Food sources of selenium<br />

Arabian dates, herring, whitebait, brazil nuts, eggs and brewer's<br />

yeast. Unfortunately, Australian soils are very low in selenium<br />

so even though foods such as garlic and grains should<br />

be rich in selenium, if the soil can't provide it, selenium<br />

won't be present in the food.<br />

Vanad turn<br />

Vanadium has a Space Age ring to it. You can imagine Judy<br />

Jetson asking her hubby for a vanadium ring for her birthday.<br />

It may be that the full personality of vanadium will be<br />

revealed on space station Mir in the year 1299, because at<br />

the present time we don't know squat (not a sausage) about<br />

the therapeutic possibilities of this mineral.<br />

There are, however, a few bits and pieces that are known<br />

about vanadium. It seems to have a role in revving up the<br />

insulin receptors on cell membranes. This would have good<br />

implications for diabetes. Vanadium has a role in bone and<br />

tooth development as well.

Zinc<br />

Zinc is another tricky mineral to absorb. As it is also in short<br />

supply in Australian soils, it comes as no surprise that around<br />

55 per cent of men and 80 per cent of women are zinc<br />

deficient.<br />

Zinc, the middle-man mineral<br />

Unlike calcium, which forms part of our skeletal structure and<br />

iron, which is a necessary component of red blood cells, zinc<br />

is a middle-man mineral. Zinc is necessary for the smooth<br />

functioning of over 200 enzymes. Enzymes are things that<br />

speed up reactions <strong>with</strong>out being used up themselves in the<br />

reaction. Sometimes they need coenzymes such as zinc in<br />

order to operate. Without zinc, no enzyme. Without enzyme,<br />

no reaction. For instance, the enzyme alcohol dehydrogenase<br />

needs zinc in order to start the conversion of alcohol so that<br />

it can be eliminated from the body. Without enough zinc,<br />

this enzyme will not function effectively, thereby allowing<br />

alcohol to keep circulating and continue damaging the body.<br />

Although we require only tiny amounts of zinc, there is no<br />

underestimating the importance of this nutrient. Zinc is<br />

required for tastebuds and olfactory (smell) receptors. In fact,<br />

one of the deficiency signs of zinc is a decreased sense of<br />

smell, taste and, consequently, appetite. Another deficiency<br />

sign is white spots on the fingernails. Zinc is needed by the<br />

immune system, especially in the manufacture of T-cells.


Getting to Know You 191<br />

Without zinc, vitamin A is poorly utilised, having repercussions<br />

for our eyesight and skin. Zinc is important for a<br />

healthy pregnancy. Zinc is also needed by the hormonal<br />

system, especially the male hormones. Men have a special<br />

need for zinc as 2 to 5 milligrams of zinc is lost in each ejaculation.<br />

Zinc is needed for healthy sperm.<br />

As zinc depends on the support of vitamin B6 and magnesium,<br />

you will often find supplements featuring this nutrient<br />

triumvirate.<br />

Conditions that might benefit from extra zinc<br />

Skin problems such as acne, eczema or psoriasis (in combination<br />

<strong>with</strong> vitamin A); low libido, infertility and impotence;<br />

loss of smell, taste and appetite; poor immune response, lots<br />

of colds, shingles, sore throat and mouth ulcers (taken in combination<br />

<strong>with</strong> vitamin C).<br />

Food sources of zinc<br />

Fresh oysters, crab, ginger root, meat, egg yolk, pecan and<br />

brazil nuts.

Good Diet<br />

On the whole, my patients have pretty good diets. Most of<br />

what I do is a bit of tidying up and reminding them of what<br />

they already know. Removing a little fat here, adding a little<br />

fibre and protein there. Suggesting a piece of fruit may<br />

improve things and perhaps a glass or two less of alcohol. All<br />

gentle prods in the right direction.<br />

But just what is the right direction? This chapter gives<br />

some broad guidelines that will help you formulate an eating<br />

plan to improve your health. A healthy eating plan is one you<br />

enjoy, is sensible, and has enough treats to keep you happy.<br />

Happiness cannot be overrated when it comes to health. If<br />

you have trouble formulating your own diet, ask for help from<br />

a naturopath or dietician, and tell them what you want.<br />

subconscious reasons: cultural identity, family preferences,

advertising, eating disorders, poverty and politics. Information<br />

is power - the more you know about food, the better<br />

chance you'have of choosing a diet that suits you and is<br />

healthy too. The following guidelines are cornerstones on<br />

which to base your eating plan.<br />

Before looking at features that make up a good diet, let's<br />

look at some of the problems of the typical Aussie diet.<br />

The Australian diet is one of the fattiest in the world,<br />

although we are heading in the right downward direction.<br />

Too much dietary fat is related to heart disease,<br />

stroke, high blood pressure, diabetes, gallstones and<br />

certain cancers. Obvious culprits are sausages, deli<br />

meat and fried food but also watch those goodies<br />

misnamed as 'health foods', such as muffins, toasted<br />

muesli, carob and tofu ice-cream.<br />

The average Australian consumes 230 teaspoons of<br />

sugar weekly. Very little is added by the teaspoonful;<br />

sugar is found in ice-cream, biscuits, sauce, even<br />

pizzas. <strong>Health</strong> problems associated <strong>with</strong> excess sugar<br />

include atherosclerosis, diabetes mellttus, child behavioural<br />

problems, gallstones, colo-rectal cancer, hypertension,<br />

CHD, obesity, Crohn's disease, kidney stones<br />

and holes in the teeth.<br />

Too much salt. Australians on average tend to<br />

consume 10 to 20 times the recommended amount<br />

of 920 to 2300 milligrams per day. Processed food is<br />

the major culprit here.<br />

The average Aussie adult consumes a yearly average<br />

of 500 middies of beer, 185 glasses of wine and 115<br />

Cornerstones to good nutrition<br />

Nutrient density<br />

Time is precious, don't waste it. The same can be said for<br />

food. Make each mouthful count; as full of nutrition as possible.<br />

I don't mean calorie-rich food but food that crams in<br />

as many micronutrients as possible. For example, take a sandwich.<br />

Sandwich (1) a Vegemite sandwich <strong>with</strong> margarine on<br />

white bread. Sandwich (2) a tuna sandwich <strong>with</strong> sprouts, beetroot<br />

and a scrape of avocado on wholemeal. Both are sandwiches,<br />

but one is a nutritional waste of time.<br />

Farnilirdty breeds contempt<br />

Our nomadic hunter-gatherer forebears ate a greater variety<br />

of foods than we do today. Mainly because they moved from<br />

region to region. Nowadays, we get very stuck in our ways:<br />

if it's Tuesday it's chops, potatoes and peas; if it's Saturday<br />

it must be Thai take-away.<br />

<strong>Eating</strong> new foods is scary. Learn from a friend whose<br />

family comes from a different ethnic background, or when<br />

you go out for dinner, choose a cuisine you are not familiar<br />

<strong>with</strong>. Be adventurous. A few dishes might be duds, but the<br />

chances are you will enhance your repetoire of food: dhal<br />

(lentil curry) from India, hommos from Lebanon, tofu from<br />

China. Another way of ensuring variety in your diet is to<br />

choose foods of different colours, particularly the fruits and


198 The C~ommonsense Guide to <strong>Eating</strong> WeiZ<br />

vegetables. Eat vegetables and fruits that are yellow, green,<br />

white and red.<br />

Grains are another culinary rut in which we tend to fall.<br />

Wheat, in particular, is difficult to avoid. Look to other grains,<br />

including rye, millet, corn, barley and oats. Try different milk<br />

products, including cow, sheep, goat, soy, almond and rice.<br />

Along the same lines, try to include foods that have a variety<br />

of tastes: salty, sweet, bitter and sour.<br />

Reguldty is worthy of regard<br />

Breakfast literally means to break your overnight fast. Unless<br />

you raid the fridge at 2 am, the likelihood is that your body<br />

goes <strong>with</strong>out nourishment from after dinner, say 7.30 pm<br />

until breakfast the following morning, say 7.30 am. This is a<br />

12-hour gap when the body is not receiving nutrients. The<br />

body can cope <strong>with</strong> this overnight fast, but any longer and<br />

trouble starts.<br />

Many people feel too rushed in the morning to think about<br />

preparing breakfast, let alone eating it. Maybe they grab a<br />

bite to eat when they arrive at work, or after dropping the<br />

kids off at school. Some people miss breakfast altogether, not<br />

eating until 11 or 12 noon or sometimes 3 pm. A 19-hour fast!<br />

Not only are your blood sugar levels going to be down to<br />

blazes, your metabolic rate will resemble that of a slug's.<br />

Treat your body like a good friend - give it nourishment<br />

regularly. Don't abuse the friendship by missing meals. Eat<br />

a good meal at least three times a day. Even more if you have<br />

a tendency for your sugar levels to drop, making you feel tired<br />

and tetchy between meals.<br />

Fresh is best<br />

Fresh food is the go, rather than processed, frozen or preprepared.<br />

Of course, it depends a lot on your lifestyle. A good<br />

meal made at the weekend when you have the time and


Good Diet 199<br />

frozen for those busy weeknights, is a lot better than a takeaway<br />

meal, or a bag of chips.<br />

When practical, eat your food in season. In the middle of<br />

winter, choose oranges and crisp apples rather than canned<br />

mangoes or imported tropical fruit. <strong>Eating</strong> food grown from<br />

the same environment, or as close as possible, is desirable,<br />

not only to be sure of freshness but also from the more philosophical<br />

stance of being connected to our environment,<br />

cementing a sense of belonging.<br />

Whole foods<br />

Choose the whole food rather than a processed version. For<br />

instance, eat the whole fruit rather than drinking the juice;<br />

go for wholegrain flour products rather than white. You will<br />

be assured of an assortment of nutrients, including fibre, vitamins<br />

and minerals normally thrown away in the processing of<br />

foods.<br />

Digestion<br />

If your digestion is poor, the best nutrition will come to<br />

nought. Some points to remember: chew each mouthful well;<br />

avoid overeating, particularly at night before going to bed;<br />

and don't drink more than 500 millilitres of fluid <strong>with</strong> your<br />

meal, because you will dilute digestive juices. It is fine to<br />

drink more than 30 minutes before a meal or a couple of<br />

hours after, when your meal has departed the stomach.<br />

Minimlse '111th' foods<br />

'111th foods' is a phrase coined by Australian doctor Ian<br />

Brighthope, which is a perfect description of the foods that<br />

(including decaf), alcohol, cigarettes, artificial sweeteners,<br />

chewing gum, deli meats, carbonated soft drinks, cooking oils,

Allergy<br />

It seems more and more people are coming down <strong>with</strong> food<br />

allergies. Either this condition is over-diagnosed or it is very<br />

common. It is probably a little of each.<br />

There are two main types of food allergy. One is known<br />

as a 'fixed' allergy, which is the drama queen of allergies.<br />

Shortly after ingestion of the culprit food, a violent immunemediated<br />

reaction occurs, such as an outbreak of hives, an<br />

asthma attack, swelling of the airways or anaphylaxis, which<br />

is a shutdown of the heart and lungs. Fixed allergies are not<br />

to be played around <strong>with</strong> - they can kill. Foods commonly<br />

associated <strong>with</strong> fixed allergies include strawberries, shellfish<br />

and the yellow food dye tartrazine (102). If you have a fixed<br />

allergy, you are usually stuck <strong>with</strong> it for life. Avoid that<br />

strawberry.<br />

The other kind of food allergy, known as 'systemic', is<br />

more subtle in its approach. Foods commonly associated <strong>with</strong><br />

systemic food allergy include eggs, milk, peanuts, wheat, soy,


206 The Commonsense Gzckde to Eatilag <strong>Well</strong><br />

tomatoes and yeast. The substance that causes the allergic<br />

reaction is called the 'allergen'.<br />

A food allergy may appear in a variety of guises, taking<br />

between one minute to several days before symptoms appear.<br />

Symptoms include mouth ulcers, chronic diarrhoea, flatulence,<br />

bladder infections such as cystitis, infections such as<br />

colds, ear infections, anxiety, depression, hyperactivity, inability<br />

to concentrate, insomnia, irritability, joint pain, asthma,<br />

bronchitis, wheezing, itchy nose or throat, sinusitis, acne,<br />

eczema, hives, itching, skin rashes, rapid heartbeat, water<br />

retention, bloating, fatigue, headaches, migraines and<br />

hypoglycaemia.<br />

Systemic allergies have appeared only recently on the<br />

scene, or they were not previously recognised as such.<br />

The following are a few theories as to why food allergies<br />

are more prevalent today.<br />

1 Fdarity breeds contempt<br />

The most common foods that cause food allergy are the<br />

most popular foods; that is, cow's milk, wheat, oranges<br />

and tomatoes. There are too many similarities for this<br />

state of affairs to be coincidence, but no-one is able to<br />

offer a solid explanation.<br />

2 Poor digestive function<br />

If food is improperly digested there is a greater chance<br />

of larger molecules crossing the intestinal wall into the<br />

bloodstream, thereby causing an allergic reaction.<br />

3 Allergy babies<br />

In industrialised countries such as our own, babies are<br />

usually weaned at six months if not earlier, when their


digestive tract is still allowing the passage of large molecules.<br />

The first foods we start them on include cow's<br />

milk, soy, orange juice and wheat, all major players in<br />

the food allergy stakes.<br />

4 Blame it on the genes<br />

A susceptib'ity to allergy can be inherited. This is especially<br />

so for fured allergies.<br />

5 The last straw<br />

In the normal course of events, our immune system is able<br />

to deal <strong>with</strong> a certain sensitivity to food allergens.<br />

However, when the immune system is under challenge,<br />

during times of stress, infections or not eating or sleeping<br />

well, the food sensitivity becomes the 'straw that breaks<br />

the camel's back' and a 'new' food allergy appears. This<br />

explains why people can suddenly become 'allergic' to a<br />

food to which they have never previously reacted.<br />

How do you recognlse a food allergy and what can<br />

you do about It?<br />

The 'gold standard' for diagnosing a food allergy is the<br />

method of food avoidance and challenge: by strictly removing<br />

the suspect food from your diet for two weeks there should<br />

be a noticeable reduction in symptoms. The suspect food<br />

should stand out like a sore thumb. Mostly, it will be a food<br />

that you eat every day, like wheat, oranges (orange juice) or<br />

milk (cheese and so on). (The challenge should never be<br />

taken by people <strong>with</strong> fixed allergies where the symptoms of<br />

an allergy may be life threatening.)<br />

Step 1: Avoid and challenge<br />

For two weeks, avoid the suspect food. Be strict. For


208 The Commonsense Gaide to <strong>Eating</strong> WeGG<br />

example, wheat would include the obvious bread, pasta and<br />

pastries, but also many processed foods which use flour such<br />

as soups, crumbed foods and so on. Look for allergy-based<br />

recipe books to help <strong>with</strong> planning meals.<br />

Keep a diary of your symptoms starting a week before you<br />

begin the allergy program, so that you can accurately compare<br />

before and after. Mention all physical and psychological<br />

symptoms, even if they don't appear to relate to the allergy.<br />

It is advisable to record other influences such as weather<br />

changes, emotional upsets, menstrual period. This diary will<br />

be invaluable in assessing the degree of allergy.<br />

When the two weeks are up it is time to take the 'challenge'.<br />

Eat a portion of the suspected allergy food three times<br />

in the one day. For example, if wheat is the suspected allergen,<br />

have toast and Weetbix for breakfast, a sandwich for<br />

lunch and pasta for dinner. Refrain from the food for two days<br />

after the challenge, as symptoms such as eczema may take<br />

that long to appear.<br />

Step 2: Abstinence<br />

Once you have ascertained that a particular food is a problem,<br />

continue fairly rigorous avoidance for a further three months.<br />

Try a few of the following suggestions to allow both the<br />

digestive and immune systems to recover.<br />

To improve digestive fgnction<br />

Take one teaspoon of herbal bitters in a wineglass of water,<br />

sipped before dinner; and take a digestive enzyme tablet <strong>with</strong><br />

each meal.<br />

Step 3: Easy does it<br />

After three months' strict avoidance, you may start to include<br />

the food back into your diet. But not all at once! Allow one<br />

serving of the allergy food every four days. This will reduce


Tailor-made 209<br />

any chance of an allergic reaction. After some experimentation,<br />

you may find that you can eat the 'allergic' food more<br />

frequently than once every four days. However, if symptoms<br />

return, back off. Each person has their own threshold, beyond<br />

which the old symptoms will appear. Note that if your<br />

immune system is compromised by an infection or stress it<br />

will be less able to cope, and so it is wise to reduce consumption<br />

of the allergy food as a precaution.<br />

I<br />

Testing<br />

No testing method, laboratory or other, is 100 per cent<br />

accurate in diagnosing a food allergy. These include the<br />

skin prick test (although helpful for atmospheric allergens<br />

such as dust mite and pollens), RAST (Radio<br />

Allergo Sorbent Test), cytotoxic (blood test), vega<br />

machine and listen machine (use acupuncture points)<br />

and kinesiology (muscle testing). However, they may be<br />

useful in confirming a reasonable suspicion.<br />

Menopause<br />

Menopause is the time when a woman's menstrual cycle<br />

ceases and quantities of the two female hormones, oestrogen<br />

and progesterone, dwindle. Rarely does it happen overnight,<br />

often taking from two to five years. When ovaries cease producing<br />

their hormones, the adrenal glands and fat cells may<br />

take over the role of hormone manufacture to a certain<br />

extent. Theoretically, this means a smooth transition from<br />

high to lower hormone levels, but unfortunately this does not<br />

always occur. The mixed bag of menopausal symptoms may


210 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

include hot flushes, depression, dry skin, less vaginal lubrication,<br />

osteoporosis, heavy bleeding, insomnia, depression<br />

and irritability.<br />

Hormone Replacement Therapy (HRT) involves taking<br />

synthetic hormones to prevent symptoms. Some women find<br />

HRT an answer to their prayers, some experience side<br />

effects, others prefer to enter this phase of their lives <strong>with</strong>out<br />

chemical interference. Many women pass through menopause<br />

symptom-free regardless.<br />

Diet<br />

Avoid sugar and caffeine. Limit your alcohol consumption to<br />

one or two glasses daily.<br />

Avoid hot spicy food and alcohol if you have hot flushes.<br />

Hot flushes may coincide <strong>with</strong> times when blood sugar levels<br />

are low; for example, half an hour before dinner. If this is the<br />

case, eat small meals frequently so that your sugar levels<br />

remain steady. Cool peppermint tea may help relieve hot<br />

flushes. Vitamin E at 1000 iu daily may also help.<br />

Eat four servings of fish a week for the omega3 fatty acids.<br />

Eat several foods containing phyto-oestrogens each day<br />

(see below).<br />

Phyto-oestrogens exert a very weak hormonal influence,<br />

much weaker than that of the real hormone produced by the<br />

ovaries. Throughout the body there are hormone receptors that<br />

work much like doorlocks, and hormones are the 'keys' that<br />

fit these locks. Phyto-oestrogens also fit these locks. Once the<br />

receptor sites are full <strong>with</strong> either phyto-oestrogens or oestrogens,<br />

any excess hormone is excreted. In this way, phytooestrogens<br />

help to normalise hormone levels. This is useful for<br />

menopause when there is too little hormone and some cancers<br />

where there is too much. Foods high in phyto-oestrogens<br />

include soy sprouts, alfalfa, green beans, split peas, olives, soybeans,<br />

tofu, soy drink, parsley, chickpeas, cherries, corn, oats,


Tailor-made 21 1<br />

barley, rye, wheat, rice, pomegranate, hops, sesame seeds,<br />

linseed, buckwheat, millet, sage, fennel, celery, carrots,<br />

cabbage, rhubarb and garlic.<br />

Other thf ngs<br />

If you suffer from vaginal dryness, insert a 500 iu vitamin<br />

E capsule into the vagina each night.<br />

Stop smoking. Smoking lowers oestrogen levels and<br />

women who smoke experience menopause on average five<br />

years earlier than women who don't.<br />

Stress can cause menopause to occur earlier and worsen<br />

existing symptoms. Look to ways of minimising stress. Buy<br />

a cat, lie in a bath, walk the dog, don't accept family<br />

invitations.<br />

Premenstrual syndrome<br />

One-third of all women suffer from premenstrual syndrome<br />

(PMS). PMS is a collection of about 150 symptoms. The most<br />

common are anger, anxiety, backache, bloating (particularly<br />

abdomen), breast tenderness, clumsiness, confusion, crying,<br />

fatigue, fluid retention, forgetfulness, headache, insomnia, leg<br />

cramps, moodiness, irritability, nausea, craving chocolate and<br />

carbohydrates, pimples, weight gain.<br />

PMS responds very well to natural remedies. Keep up the<br />

regimen for at least four menstrual cycles.<br />

Diet<br />

Vegetarian women suffer less from PMS than meat-eating<br />

women do, because more fibre is consumed in the diet.<br />

Soluble fibre is able to stop cholesterol and excess oestrogen<br />

from recirculating.<br />

Reduce red meat and dairy foods.


212 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

Eat fish four times a week to provide the omega-3 fatty<br />

acids, which will help ease the inflammatory symptoms of<br />

PMS.<br />

Cut out all sugar, salt and white flour products. A study<br />

revealed that women <strong>with</strong> PMS consumed 275 per cent<br />

more refined sugar and 62 per cent more white flour products<br />

than did women <strong>with</strong>out PMS. It also found that<br />

women <strong>with</strong> PMS consume 79 per cent more sodium.<br />

Caffeine will make all symptoms worse, especially anxiety<br />

and depression. You may drink a cup or two a day in the<br />

first two weeks of your cycle, but after day 15 don't even<br />

think about it. The same goes for chocolate and cola<br />

drinks. Caffeine affects hormones adversely, as well as<br />

being a major contributor to fluctuations in blood sugar<br />

levels. The xanthines in coffee and chocolate have an<br />

effect on oestrogen receptors in the breasts, contributing<br />

to breast tenderness and enlargement. Drink dandelion<br />

root coffee instead. Dandelion root is good for the liver,<br />

which metabolises excess hormones.<br />

If your PMS symptoms include cravings for sweet food,<br />

mood changes or forgetfulness, adopt the eating pattern<br />

suggested for hypoglycaemia on page 25, which basically<br />

entails eating small meals regularly.<br />

Eat only organically grown chooks and eggs as they are not<br />

pumped up <strong>with</strong> extra synthetic oestrogen.<br />

Other things<br />

There are several good 'women's formulation' multivitamin<br />

and mineral supplement tablets available specifically<br />

for PMS; they have higher amounts of B6, magnesium and<br />

zinc.<br />

Take extra magnesium and vitamin B6 a week before<br />

your period is due, particularly if you suffer from breast


Tailor-made 213<br />

tenderness, weight gain, fatigue, anxiety, cramping and<br />

nervous tension.<br />

Take vitamin E 300 to 600 iu daily throughout the month.<br />

Vitamin E will relieve breast tenderness.<br />

@ Evening primrose oil (EPO) is very successful in relieving<br />

many of the symptoms of PMS. It contains gamma linolenic<br />

acid (GLA), which is converted in the body into<br />

hormone-regulating prostaglandins. In order to be<br />

effective, GLA needs to be incorporated into every cell,<br />

which is why you need to take EPO for several months.<br />

Take 3 grams of EPO daily.<br />

Overweight<br />

With all the pressure society places on not being overweight,<br />

you would have to be a masochist to want to be fat. It is,<br />

therefore, unfair to blame people for eating too much, when<br />

it is obvious that eating too much is the cause of their overweightness.<br />

Hormonal problems do have a role in obesity, but<br />

only a very few people have entirely hormonal weight problems.<br />

Overeating is an addiction to food which should be<br />

given the same consideration as any other addiction. When<br />

we were babies and terribly vulnerable, a source of comfort<br />

and nourishment was mother's milk (or formula). When we<br />

were afraid or tired or angry and cried, we were given the<br />

breast or bottle. When we are upset or stressed, many of us<br />

still need to feel comforted, just as we did when a baby. Some<br />

people choose alcohol, some people choose cigarettes, others<br />

seek solace in chocolate.<br />

Is your mother overweight? Is your father overweight? Are<br />

your sisters and brothers overweight? Whether it is nature or<br />

nurture, a higher proportion of overweight: people have overweight<br />

families. Another reason for overweight is one diet too


214 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

many. The truth will out! People who have been on many<br />

diets, particularly low calorie ones, tend to be more overweight<br />

than those who have never dieted. We now know that<br />

dieting interferes <strong>with</strong> metabolism, which slows down as we<br />

reduce the amount we eat, creating a vicious cycle. The metabolic<br />

rate is the rate at which energy is used and released<br />

by the cells. A higher metabolic rate means that more energy<br />

is used and more body fat is burned for energy. A low or<br />

sluggish metabolism means that cells are more thrifty in their<br />

use of energy and calories.<br />

Diet<br />

Before you do a thing, write a complete diet diary for one<br />

week. Don't change a thing and don't judge. Take this diary<br />

to a dietician, to sort out any problem areas; for instance,<br />

missing breakfast, a cafe latte too many, too much hidden fat.<br />

Along <strong>with</strong> all food and drink, keep a written record of your<br />

emotions. Sometimes we don't realise we are eating because<br />

of something emotional, such as boredom, fear, or rage.<br />

Fat, protein, carbohydrate and alcohol contain calories. If<br />

we consume more than our bodies need, we can store the<br />

rest as fat (except for protein, which is not stored, but<br />

should not be eaten in excess of needs; that is, 1 gram per<br />

body kilogram daily). Recent research has shown that<br />

excess fat is more likely to be stored as fat than excess<br />

carbohydrate is. In practice, choose a baked spud over a<br />

chip. To become more savvy <strong>with</strong> what's fat and what's<br />

not, buy a nutritional counter showing the fat content of<br />

food. Alcohol is also stored as fat, avoid it.<br />

Eat small meals often, according to the hypoglycaemia diet<br />

on page 25. That is, a little protein <strong>with</strong> carbohydrate every<br />

two to three hours, so that you don't have a chance to get<br />

hungry. <strong>Eating</strong> frequently will increase your metabolic rate.<br />

No more than 25 per cent of your total calories should


Tailor-made 215<br />

come from fat. If your dietary requirements were 1200 to<br />

1500 calories a day (a reasonable amount for most people),<br />

your fat intake should not exceed 33 to 42 grams of fat a<br />

day.<br />

Eat smaller portions of food but don't starve yourself, even<br />

missing breakfast causes a drop in your metabolic rate.<br />

Your diet should resemble the suggested format on page 203.<br />

Focus on low fat, high fibre and protein-rich foods.<br />

Other things<br />

Exercise is an absolute must in any weight loss program.<br />

Make it a priority to exercise for 40 minutes, five times a<br />

week. The best kind of exercise will have you puffing, such<br />

as hill walking, cycling, jogging or gym work. Don't be<br />

alarmed if you put on some weight. But you should lose<br />

centimetres. Muscle tissue weighs more than fat but uses<br />

more energy.<br />

Skin<br />

Beauty may be more than skin-deep but having beautiful<br />

skin never hurt anyone. Skin is our largest organ and reflects<br />

our state of health and mind. Skin is often the first indicator<br />

that things are going awry. Many people find that their skin<br />

reacts when they are under stress, whether it is an outbreak<br />

of eczema, acne or just looking tired and lacklustre.<br />

The following recommendations are not specific to any<br />

particular skin problem but will invariably go a long way to<br />

helping any skin disease including excema, acne and psoriasis.<br />

These recommendations will help to transform your skin<br />

to peak condition.<br />

Drink water like there is no tomorrow; pure water,


216 TAe Commonsetsse Guide to <strong>Eating</strong> <strong>Well</strong><br />

anywhere between 2 to 3 litres. Yes, your bladder will complain<br />

but will eventually calm down after realising you are<br />

serious. Unless your skin is fully hydrated, there is no<br />

chance of looking good.<br />

In addition to the water, drink one carrot juice daily (for<br />

the beta-carotene), as well as two to three herbal teas.<br />

Choose from red clover, burdock, nettle or a combination.<br />

These are traditional herbal 'blood purifiers' that work at<br />

cleaning the body from the inside out.<br />

Avoid tea, coffee, chocolate, cheese and sugar.<br />

Avoid deep-fried foods, although some kinds of fat are<br />

good and will bring sleekness to your skin. Eat fish<br />

(contains the omega3 fatty acids. Have you ever seen a<br />

seal <strong>with</strong> bad skin?). Other foods <strong>with</strong> 'good' fats include<br />

avocados, seeds, tahini and nuts.<br />

Evening primrose is beautiful for skin, particularly if your<br />

skin is affected by hormones or eczema. Take 3 grams<br />

daily.<br />

Vitamin A and zinc are excellent for all skin problems.<br />

Take a tablet of each daily.<br />

B-complex is a must, particularly if stress is a trigger.<br />

Exercise regularly, washing off sweat as soon as possible.<br />

Drink plenty of water before, during and after exercise to<br />

avoid your skin dehydrating. In addition, you might like to<br />

combine a few drops of rosewater in pure water and spray<br />

over the face and neck after exercise.<br />

Creative visualisation, a type of meditation, may improve<br />

your skin. Each day, for a few minutes, visualise your skin<br />

as clear and blemish-free; think of swimming in a cool lake<br />

under moonlight.<br />

Use an oat sock (see page 106) or sorbolene instead of soap.<br />

Massage olive or jojoba oil all over the body before you<br />

shower or bath. The warm water will help your skin to<br />

absorb the oil.

Stress<br />

Stress is a major cause of illness - a fact that most of us<br />

intuitively know. The science that has gone about proving<br />

our hunch is called psychoneuroimmunology and it acknowledges<br />

the connection between the mind (psych), nervous<br />

and hormonal systems (neuro) and the immune system<br />

(immunology). Described succinctly by Deepak Chopra,<br />

modern guru of the mindlbody connection: 'The mind and<br />

body are like parallel universes. Anything that happens in the<br />

mental universe must leave tracks in the physical one.'<br />

Lifestyle changes take precedence in dealing <strong>with</strong> stress,<br />

although dietary changes and supplements can mitigate its ill<br />

effects. Most people who are stressed feel pressed for time,<br />

unable to fit another thing into their hectic schedule. This is<br />

the most telling sign that time-out is precisely what is<br />

needed. Time-out to exercise and meditate - about 20<br />

minutes of each and every day. If you change your day to<br />

ensure these two things take priority over business or social<br />

demands, you will be healthier and happier. I can't vouch for<br />

wealthier!<br />

Diet<br />

If you are stressed, now is not the time for radical dietary<br />

changes. Ease into it slowly. Maybe exit the coffee first and<br />

in a couple of weeks try another change.<br />

Never miss a meal. When blood sugar levels are low, the<br />

symptoms of stress increase. Eat small meals regularly,<br />

every three to four hours. Each meal should contain a small<br />

portion of protein; for example, egg, cheese, nuts, beans,<br />

fish.<br />

Give sugar a miss. This includes the 3 pm chocolate hit.<br />

You will no doubt love that hit of sugar that stops you<br />

feeling so tired, but your body doesn't. The extreme highs


218 The Commonsense Guide to <strong>Eating</strong> WeZZ<br />

and lows of blood sugar levels leave you more depleted.<br />

<strong>Eating</strong> sweet foods when stressed is like cruelty to a dumb<br />

animal. You.<br />

Brown rice, oats, root vegetables (such as carrots and parsnips)<br />

and legumes (such as kidney beans and lentils) are<br />

grounding and very nurturing for the stressed nervous<br />

sys tem.<br />

There is room for 'comfort' food in the anti-stress diet,<br />

particularly in times of high stress. These may be foods of<br />

your childhood, such as a roast dinner, porridge, rice<br />

pudding, moussaka.<br />

Caffeine is O.U.T. If you find a cup of coffee relaxing, it<br />

is probably because you are addicted to the stuff. Kick the<br />

habit. Caffeine increases the release of adrenalin the stress<br />

hormone, something that is working overtime anyway.<br />

Avoid coffee and caffeine-containing things, such as cola<br />

drinks and guarana. Be prepared for whopping caffeine<br />

<strong>with</strong>drawal headaches 18 hours after your last cup of coffee.<br />

Swear at me if you wish, it will take up to 48 hours. Once<br />

released from caffeine's grip, take your comfort from a<br />

range of herbal teas (see page 90) or one or two cups of<br />

tea. While tea contains caffeine, it is not absorbed to the<br />

same extent.<br />

Although it is tempting to drown your troubles, alcohol is<br />

counterproductive. It is a nervous system depressant. After<br />

the initial euphoria, alcohol can leave you feeling more<br />

stressed.<br />

A B-complex vitamin is important at this time. Take one<br />

each morning.<br />

Take at least 1 gram of vitamin C daily; the adrenal glands<br />

chew up vitamin C during stress.<br />

Potassium is good for nerves and magnesium is good for<br />

tense muscles - you probably need both by the truckload.<br />

Stress-relieving herbs support the adrenal glands, the


nervous and immune systems. These include passionflower,<br />

scullcap, valerian, licorice, St John's wort, panax and<br />

Siberian ginseng, lemon balm, kava and chamomile.<br />

<strong>Health</strong>y heart<br />

Heart disease commonly manifests as atherosclerosis, <strong>with</strong><br />

the main symptoms being high blood pressure and high cholesterol.<br />

Heart disease is a big killer in Australia and other<br />

industrialised countries. Of course there are hereditary considerations,<br />

but there is no denying that diet and lifestyle play<br />

a huge part in heart disease.<br />

Don't just think about it, you mast start managing your<br />

stress. Do something for it every day - walking, tapestry,<br />

singing, meditation, rock climbing, yoga, dancing, counselling.<br />

Regular aerobic exercise decreases LDL levels and most<br />

atherosclerosis risk factors. Being overweight is a risk factor.<br />

Lose it. And stop smoking if you possibly can.<br />

Diet<br />

Be firm in restricting fats. A low-fat diet is recommended,<br />

where less than 25 per cent of total calories come from fat.<br />

Avoid fried and processed foods that often contain hidden<br />

oils. Although cholesterol in food is a factor, it is more<br />

important to limit the fats, particularly the saturated fats in<br />

the diet; for example butter, cream, ice-cream, full cream<br />

milk, lard, beef, lamb, bacon, organ meats, eggs, pork, delimeats<br />

and yellow cheese.<br />

Taking a leaf from the French who seem to have beaten<br />

the heart-disease odds (see French Paradox, page 173), you<br />

may indulge in olive oil, cold-pressed vegetable oils and<br />

fish. Eat fish particularly, as it is full of the protective


220 The Commonsense Guide to <strong>Eating</strong> <strong>Well</strong><br />

omega3 fatty acids. Eat four servings of the critters each<br />

week: canned or fresh but definitely not fried.<br />

For many years, salt was classified as a baddy because it<br />

was thought to increase blood pressure. Now, the jury is<br />

out. It seems that some of us are 'salt sensitive', while<br />

others may soak in brine and not be affected. Nevertheless,<br />

don't be heavy handed <strong>with</strong> the saltcellar.<br />

The following foods do not contain cholesterol but are able<br />

to increase our blood levels of this risk factor: coffee,<br />

alcohol (over two glasses daily), sugar and hydrogenated<br />

fats such as margarine.<br />

Soluble fibre (see page 29) reduces cholesterol by preventing<br />

it from being absorbed or reabsorbed. The soluble<br />

fibre 'chelates', or holds on to, the cholesterol and eliminates<br />

it via the bowel. Good choices include oat bran, rice<br />

bran, barley bran, vegetables, fruit, legumes, pectin and<br />

psyllium.<br />

Foods <strong>with</strong> cholesterol-lowering effects on the body<br />

include artichokes, ginger, cucumber, seaweed, banana,<br />

quince, onion, garlic, ginger, pineapple, oatmeal, legumes,<br />

grapefruit, oranges, apples, yoghurt, carrots, barley, eggplant<br />

and shiitake mushrooms.<br />

The liver is able to make bile from cholesterol. Be kind to<br />

your liver: drink the juice of half a lemon in hot water each<br />

morning before breakfast and/or sip a teaspoon of herbal<br />

bitters in a glass of water before dinner each night.<br />

The antioxidants are big news in the treatment of heart<br />

disease, particularly in preventing and reversing the<br />

damage to arteries from atherosclerosis. Take one vitamin<br />

and herbal antioxidant (containing grapeseed) tablet daily.<br />

In addition to eating fish, take evening primrose oil, 3<br />

grams daily.<br />

Lecithin regulates cholesterol levels. Take one teaspoon or<br />

four capsules daily.


Glossary<br />

Amylase An enzyme present in saliva and pancreatic juice,<br />

which is responsible for breaking down carbohydrates into<br />

smaller units.<br />

Antioxidants A substance that protects against damage<br />

from free radicals. The body makes its own antioxidants,<br />

such as catalase and superoxide dismutase. Various nutrients<br />

also act as antioxidants including vitamin A, beta-carotene,<br />

vitamins C and E, selenium, zinc and bioflavonoids.<br />

Carcinogen A general term for an agent that can cause<br />

cancer. Examples include cigarette tar; ultraviolet radiation<br />

(sunlight); fats that have become oxidised (rancid); the<br />

nitrates used for colouring and preserving meats such as<br />

salami; and the pesticides and fungicides used on our agricultural<br />

produce.<br />

Chelate The word chelate is derived from the Greek word<br />

for claw. A chelating agent grabs on to another substance.<br />

This can be used to either take substances out of the body<br />

or to enhance their absorption, depending on the particular<br />

chelating agent.<br />

Cytoplasm The jelly-like substance that surrounds the<br />

nucleus in the cell.<br />

Diuretic A substance that increases the volume of urine, by<br />

increasing the amount of salts and water exreted via the<br />

kidneys.


222 The Commonsense Guide to Eatilag <strong>Well</strong><br />

Dysbiosis A state of bowel microflora disharmony.<br />

Alcohol dehydrogenase The enzyme necessary for converting<br />

alcohol, mainly found in the liver. Alcohol dehydrogenase<br />

requires the mineral zinc to function.<br />

Emulsify To make an emulsion. An emulsion is a liquid<br />

mixture where an oily substance is combined <strong>with</strong> water<br />

substance and the two don't separate. Lecithin is an<br />

exmple of an emulsifier as it is both fat- and water-soluble.<br />

Enzyme An enzyme is a protein that, in small amounts,<br />

speeds up the rate of a biological reaction <strong>with</strong>out being<br />

used up in that reaction. Enzymes are used extensively<br />

in the body for all manner of things. Enzymes often<br />

require coenzymes, such as magnesium and zinc, in order<br />

to work efficiently. Heat and pH may also slow or speed<br />

enzyme activity. Enzyme names often end in 'ase'; for<br />

example, lactase and alcohol dehydrogenase. The digestive<br />

enzymes are predominantly used to break down<br />

bigger food fragments into smaller fragments. For<br />

instance, carbohydrate-splitting enzymes (amylase) are<br />

able to split a complex carbohydrate into one and two<br />

sugar units.<br />

Free radical A free radical is defined as any molecule that<br />

has an unpaired electron in its outer orbit. Molecules like<br />

their electrons paired, so this situation is disturbing. The<br />

free radical molecule <strong>with</strong> the unpaired electron is unbalanced<br />

and therefore highly reactionary. In non-technical<br />

language, they are troublemakers! Although they are tiny,<br />

free radicals can wreak havoc to our cells. Free radicals<br />

cause harm in two distinct ways. First, to the cell<br />

membrane. The damage means that nutrients and oxygen<br />

cannot enter the cell from the bloodstream and, conversely,<br />

waste products are unable to leave the cell. This effectively<br />

means a cell's death. Second, free radicals may also<br />

enter the cell and disturb the FWA and DNA, our cell's


Glossary 223<br />

genetic material. Mutations will occur when the cell next<br />

divides if free radicals have changed the genetic code.<br />

There is some evidence to suspect this could explain the<br />

mechanism by which some cancers are caused.<br />

Glucose Tolerance Factor (GTF) A molecule made up<br />

of 2-nicotinic acid, cysteine, glycine, glutamine and chromium.<br />

Is a cofactor for insulin, facilitating entry of glucose<br />

across cell membrane.<br />

Glycolysis A ten-step conversion of glucose to pyruvic acid<br />

to lactic acid. Glycolysis takes place in the cytoplasm of<br />

cells and involves the production of a small amount of<br />

energy that is used for the workings of the cell.<br />

Goitre Swelling of the neck due to an enlargement of the<br />

thyroid gland. The goitre could be due to under- or overfunctioning<br />

or simply an overgrowth or tumour of the<br />

thyroid gland.<br />

Haemoglobin An iron-containing substance <strong>with</strong>in red<br />

blood cells, capable of carrying oxygen.<br />

Haemosiderin A storage form of iron found particularly in<br />

the liver.<br />

Half life The time it takes to reduce the level in the body<br />

(of a particular substance - for example, caffeine) to half<br />

its initial value.<br />

Hypothalamus The part of the brain that controls various<br />

bodily functions including thirst, temperature, water<br />

balance, hunger and so on.<br />

Insulin A hormone secreted by the pancreas that is important<br />

for regulating the amount of glucose in the blood.<br />

Interstitial fluid The fluid between cells.<br />

Intrinsic Factor (IF) A protein substance secreted in the<br />

stomach. It is necessary for the absorption of vitamin B12.<br />

A failure of secretion of Intrinsic Factor leads to pernicious<br />

anaemia.<br />

Isoflavones Plant substances found in legumes - for


224 The Commonsense Gzlide to <strong>Eating</strong> <strong>Well</strong><br />

example, genistin in soy - which are structurally similar to<br />

oestrogen, and are able to bind on to oestrogen receptors.<br />

Lipoprotein A protein-coated vehicle that transports fatty<br />

substances including cholesterol, triglycerides, phospholipids,<br />

hormones and fat-soluble vitamins around in the<br />

bloodstream. Sometimes called LPs (I've always wondered<br />

what happened to vinyl records).<br />

Miso A fermented soy paste made by inoculating trays of<br />

rice <strong>with</strong> the mould AspeqZas oqzae. A ground preparation<br />

of cooked soybeans and salt is then mixed in and the mass<br />

is allowed to ferment for several days before being ground<br />

into a paste that has the consistency of peanut butter. The<br />

entire miso process takes 10 to 40 days. Miso is used as a<br />

flavouring for soups and on vegetables. It is a source of<br />

B12 as well as bowel friendly bacteria.<br />

Oligosaccharide Undigestible starch found in seeds and<br />

beans.<br />

Peristalsis A wavelike movement that progresses along<br />

some of the hollow tubes of the body, particularly the<br />

bowel.<br />

Phytates Not a fire, although often in cereals and legumes.<br />

Phytates or phytic acid can reduce the absorption of certain<br />

minerals including iron, zinc and calcium. Phytic acid is<br />

the calcium or magnesium salt of inositol and phosphoric<br />

acid. Phytates are destroyed by heat and phytase. Phytase<br />

is an enzyme present in grains and also in kidneys.<br />

Pica <strong>Eating</strong> non-nutritious substances such as stones, chalk,<br />

dirt or ice. May be due to a deficiency of minerals, particularly<br />

iron.<br />

Portal circulation Venous blood flow from the intestines<br />

(spleen, stomach) to the liver.<br />

Probiotics Beneficial microflora in the bowel; for example,<br />

LactobacilIzls acidophilas.<br />

Smooth muscle (or involuntary muscle) Occurs in


Glossary 225<br />

hollow organs such as the bowel, blood vesels, gall bladder<br />

and uterus.<br />

Solvent A liquid that can hold dissolved substances.<br />

Superoxide dismutase An antioxidant enzyme in the<br />

body. Can contain copper, manganese or zinc.<br />

Triglyceride A fat consisting of three fatty acid molecules<br />

combined <strong>with</strong> one glycerol molecule. Triglycerides are<br />

the most common type of fat found in the body and in<br />

food.<br />

Unsaturated fatty acid A fatty acid (chain or carbons)<br />

where there is one or more double bonds.
