IS INSULIN RESISTANCE<br />
THE HIDDEN EPIDEMIC<br />
DRIVING MODERN DAY<br />
DISEASE?<br />
Image: Lightwise © 123rf.com<br />
Could focusing on how food affects our blood sugars — even when we aren't diabetic — be key<br />
to beating chronic disease as well as obesity? Alice Ball writes<br />
“<br />
I<br />
nsulin resistance is the epidemic<br />
you’ve never heard of,” writes<br />
scientist and researcher<br />
Benjamin Bikman, PhD, in his <strong>2021</strong><br />
book Why We Get Sick. And he could be<br />
right; because with another New Year<br />
behind us, how many of us — without<br />
understanding the role that insulin plays<br />
in obesity — will once again succumb to<br />
the prevailing narrative that if we just eat<br />
less and move more, the post-Christmas<br />
weight gain will take care of itself?<br />
8 OPTIMUM NUTRITION | WINTER <strong>2021</strong>/22
Feature<br />
IN BRIEF<br />
• Research suggests insulin<br />
resistance rather than overeating is<br />
the primary cause of obesity.<br />
• Insulin resistance can also be<br />
driven by stress and poor sleep.<br />
• Insulin resistance drives chronic<br />
diseases including heart disease,<br />
dementia and type 2 diabetes.<br />
• A low carb diet can support insulin<br />
sensitivity and reverse type 2<br />
diabetes in some instances.<br />
• Glucose tolerance (i.e. the amount<br />
of carbohydrate your body can<br />
handle) varies between individuals.<br />
Growing evidence suggests that our<br />
bodies do not act like bank accounts<br />
for calories. One recent paper,<br />
published in the American Journal of<br />
Clinical <strong>Nutrition</strong>, suggests that insulin<br />
resistance, rather than overeating, is<br />
the primary cause of obesity. It also<br />
lays the blame for obesity on excessive<br />
consumption of foods with a high<br />
glycaemic load (GL); in other words,<br />
rapidly digestible carbohydrates. These<br />
foods, the researchers propose, cause<br />
changes to the hormone insulin, which<br />
changes metabolism, and drives fat<br />
storage, weight gain and obesity. 1<br />
So this January, rather than focusing<br />
on how much we’re eating, could<br />
focusing on what we’re eating and how<br />
it affects our insulin be the key to losing<br />
weight?<br />
Lock and key<br />
Insulin is a vital hormone, with the<br />
essential job of getting rid of sugar in<br />
our bloodstream after we eat. Think of<br />
it like a lock and key mechanism. Sugar<br />
(glucose) in the blood is trying to get<br />
through the door of the cell. But to get<br />
inside, it must have a key to open that<br />
door. Insulin is that key.<br />
But what happens if you have too<br />
much sugar in your bloodstream? Then,<br />
the doors of the cell become resistant<br />
to the insulin — think of the keyhole<br />
getting rusty through over-use. This<br />
means that the pancreas has to pump<br />
out more insulin to try to get the cells to<br />
unlock, thus elevating levels of insulin.<br />
Excess sugar can also get pushed<br />
into belly fat and the liver. The latter<br />
is what’s known as non-alcoholic fatty<br />
liver disease (NAFLD); a condition<br />
that affects around a quarter of<br />
the developed world. NAFLD also<br />
interferes with the action of insulin<br />
itself, which means the pancreas has to<br />
produce even more insulin to get rid of<br />
all the sugar from your blood.<br />
Insulin acts as a key for opening cells to store glucose away as energy (left); when cells<br />
become 'insulin resistant', glucose remains in the blood, raising blood sugars (right)<br />
Insulin resistance can be considered<br />
a spectrum as, over time, more and<br />
more cells become resistant to insulin.<br />
Eventually, the pancreas gets worn out<br />
and can no longer produce enough<br />
insulin to overcome the cells’ resistance.<br />
The result is type 2 diabetes.<br />
The driver of disease<br />
Whilst not all of us might be diagnosed<br />
as diabetic, Bikman’s book raises the<br />
question as to whether many of us are<br />
somewhere on this insulin resistant<br />
spectrum, and that this is driving<br />
chronic disease.<br />
“People don’t die from insulin<br />
resistance,” Bikman tells <strong>Optimum</strong><br />
<strong>Nutrition</strong>. “They die from the diseases<br />
that insulin resistance is causing.<br />
Alzheimer’s disease, heart disease; those<br />
are the complications that are arising<br />
from the insulin resistance, which<br />
ultimately prove lethal.”<br />
When it comes to heart health, for<br />
example, Bikman says that insulin<br />
resistance promotes higher blood<br />
pressure. “It does this through several<br />
different mechanisms. One is forcing<br />
the kidneys to hold onto more salt than<br />
normal, which means they’re forced to<br />
hold onto more water as well. And if<br />
they’re holding onto more water, blood<br />
pressure starts to climb.”<br />
Insulin also helps to promote the<br />
dilation of our blood vessels, he adds.<br />
However, when the blood vessels<br />
become insulin resistant, they stay<br />
constricted and can’t move as much<br />
blood as they did before, causing blood<br />
pressure to increase.<br />
“People don’t die from insulin resistance…They die from the diseases<br />
that insulin resistance is causing…"<br />

Interview<br />
HISTORIAN ANNIE GRAY<br />
DELIVERS A LESSON ON<br />
BRITISH FOOD<br />
Food historian and Radio 4 regular Dr Annie Gray talks to Alice Ball about why the current<br />
adage to ‘eat what your great grandmother ate’ for healthier nutrition may, in fact, be misguided<br />
Y<br />
ou may have heard experts<br />
say: ‘Don’t eat anything your<br />
great-grandmother wouldn’t<br />
recognise as food’, but Dr Annie Gray<br />
(PhD) isn’t so convinced. According<br />
to the food historian, eat how your<br />
ancestors ate and you could end up<br />
with gout — an arthritic condition<br />
considered something of a “disease de<br />
jour” in the 18th century.<br />
“People romanticise the past,” she<br />
says over a video call. “They think we<br />
all lived in harmony with everything,<br />
but they forget that the diet of the poor<br />
was awful — and in many ways, the diet<br />
of the rich was too.”<br />
The 19th century is another case<br />
in point. “You’ve got the poor reliant<br />
upon bread,” she says. “That in itself<br />
isn’t that bad — a good loaf of bread is<br />
pretty good for you — but the trouble<br />
is the bread wasn’t good quality. It was<br />
always made from white flour, which<br />
has got the wheat germ taken out, and<br />
then if you’re dirt poor you’re probably<br />
putting sweetened condensed milk on it<br />
which is largely just sugar.”<br />
Malnutrition also takes many forms,<br />
she says. “You can be malnourished<br />
in the 19th century and it will show<br />
OPTIMUM NUTRITION | WINTER <strong>2021</strong>/22<br />

because you’re incredibly thin and<br />
you’re not getting the nutrients you<br />
need, or you can be malnourished<br />
in the 21st century and be grossly<br />
overweight. Those two are just two sides<br />
of the same coin.”<br />
Gray, a broadcaster, writer and cook,<br />
has specialised in the history of food<br />
and dining in Britain for more than a<br />
decade, focusing on the 17th century<br />
onwards. You name it, she’s eaten it;<br />
from kangaroo brain cakes (“tasted<br />
a bit like spam, to be honest”) to an<br />
“epic” boar’s head during a Tudor<br />
feast. Since 2012, she’s been a regular<br />
panellist on BBC Radio 4’s The Kitchen<br />
Cabinet, and her latest book of the same<br />
name (fully titled The Kitchen Cabinet:<br />
A Year of Recipes, Flavours, Facts, &<br />
Stories for Food Lovers), which delves<br />
into Britain’s culinary past and present,<br />
was published in September <strong>2021</strong>.<br />
So she is perhaps well qualified to<br />
declare that insults thrown at British<br />
cuisine (or, perhaps, Britain’s lack of<br />
cuisine) are “total baloney”.<br />
“Britain has a really good food<br />
heritage both in terms of British dishes<br />
— roast meat, fish and chips, and pork<br />
pie — and our own food culture going<br />
backwards,” she says. “Yes, French<br />
cuisine was what ruled the roost in<br />
terms of the aristocracy for much of the<br />
past 500 years, but that was true right<br />
across the world — certainly among<br />
English speaking and European areas.”<br />
She does, however, believe that<br />
British food suffered after the Second<br />
World War — another reason why<br />
modelling your grand- or greatgrandmother’s<br />
diet mightn’t be the best<br />
approach.<br />
“I think a lot of people don’t realise<br />
that during the war, rationing was bad.<br />
But after the war it became worse,” she<br />
says. “And when you think about kids<br />
growing up, you’re eight when the war<br />
breaks up, but you’re probably married<br />
“I think a lot of people don’t<br />
realise that during the war,<br />
rationing was bad...but after<br />
the war, it became worse...”<br />
“We’ve both reduced the number of things we eat, but also in<br />
some ways we’ve got too much variety in others. You can get 20<br />
different varieties of pasta or five different types of ketchup...”<br />
with kids by the time rationing ends.<br />
That chance to learn, that transition<br />
of knowledge [about good food], isn’t<br />
really there.”<br />
It’s perhaps an ironic statement,<br />
considering that during her own<br />
teenage years, Gray survived on<br />
microwave meals. “My mother really<br />
couldn’t cook and my dad sort of<br />
could, but it was classic 1980’s family<br />
fare,” she says.<br />
This changed when the family moved<br />
to France during her A-levels, and Gray<br />
boarded with a French family. “It’s<br />
a bit of a cliché, but it was this total<br />
epiphany where I suddenly realised that<br />
food could be incredible.<br />
“My mother’s omelettes were always<br />
awful — you could bounce them off<br />
the ceiling. But I had one in France<br />
and was like ‘This isn’t an omelette’,<br />
because it was cooked in so much<br />
butter and unbelievably good.<br />
“I think it was at that point I realised<br />
if you’re going to eat three times a<br />
day, you should make it count.” At the<br />
University of Oxford, where she studied<br />
modern history, she was “the person<br />
who was roasting pheasant and making<br />
[her] own pasta”, despite a lack of<br />
cooking facilities.<br />
Yet after graduating, she still had no<br />
idea what she wanted to do and ended<br />
up “getting sacked from basically every<br />
job”.<br />
“I decided I would go back and do<br />
a masters [in historical archaeology]<br />
because I still loved history,” she says.<br />
“Then I left, got sacked a few more<br />
times and did a PhD. By this time I<br />
knew I wanted to study food and I<br />
knew I wanted to work with museums.<br />
The PhD allowed me to do those<br />
things.”<br />
“Greater choice…all an illusion”<br />
According to Gray, one of the biggest<br />
differences between historic and<br />
modern day diets is the variety of<br />
what we eat. With advances in trade,<br />
technology and travel, it can often<br />
appear like we have greater choice over<br />
our diets. But this, she says, is “all an<br />
illusion”.<br />
“There were 3,000 varieties of apples<br />
in the Victorian era, but today you walk<br />
into the average supermarket and get<br />
five, and they’re all enzyme treated.<br />
“We’ve both reduced the number<br />
of things that we eat, but also in some<br />
ways we’ve got too much variety in<br />
others. You can get 20 different varieties<br />
of pasta or five different types of tomato<br />
ketchup.”<br />
Certain vegetables have also<br />
disappeared from modern day diets<br />
completely; skirret (a root vegetable),<br />
scorzonera (similar to parsnip) and<br />
salsify (a root vegetable with an oysterlike<br />
taste).<br />
Jerusalem artichokes, which are<br />
beneficial for gut health, were also<br />
eaten habitually, and when it came to<br />
meat, every part of the animal would be<br />
eaten.<br />
Yet meat was “very much for the<br />
rich”. Historical cookbooks tend to<br />
draw attention to meat consumption,<br />
but this is only because the “food that<br />
gets the publicity is the stuff the rich<br />
ate”, she says.<br />
“We get this skewed idea that<br />
everybody ate loads of meat, very<br />
plainly done with some vegetables on<br />

cooking techniques and spices that also<br />
set them apart. For example, cooking<br />
with fennel and black pepper in Tamil<br />
cooking dates back centuries as both are<br />
locally grown.<br />
“When we think of Andhra Pradesh,<br />
the misconception of the local food<br />
being searingly hot couldn’t be [further]<br />
from the truth. My favourites are the<br />
Andhra lamb chops curry with tamarind<br />
and ginger, from the lamb chapter in<br />
Thali, and also an Andhra thali which<br />
gives an insight into how the food from<br />
this region is diverse, full of flavour and<br />
simple to cook.”<br />
KERALA FISH MOILEE (CLASSIC COCONUT FISH CURRY)<br />
Maunika says:<br />
“A classic fish curry with chilli, pepper,<br />
curry leaves and turmeric simmered<br />
in coconut milk, this southern Indian<br />
fish curry is a staple in every household<br />
because it is so simple to cook. I like to<br />
serve it with rice and cucumber salad.<br />
Ask your fishmonger to cut the fish into<br />
steaks, as they will do it expertly and<br />
ensure that the steaks still hold together<br />
with the help of a central bone.”<br />
Ingredients<br />
• 1 tsp ground turmeric<br />
• Pinch of salt<br />
• Juice of ½ lime<br />
• 600g cod, monkfish or sea bass, cut<br />
into 3.5cm steaks<br />
• 60g white onion, roughly chopped<br />
• 4 cm ginger root, roughly chopped<br />
• 4 garlic cloves, roughly chopped<br />
• 2 tbsp oil<br />
• 1 tsp black mustard seeds<br />
• 5 green cardamom pods, whole<br />
• 2 green chillies, slit lengthways<br />
• 5–7 curry leaves<br />
• 100ml water<br />
• ½ tsp sugar<br />
• Salt, to taste<br />
• 400ml coconut milk<br />
• 1 heaped tsp tamarind paste<br />
• ½ tsp freshly ground black pepper<br />
• Coriander<br />
For the garnish<br />
• 2 tbsp chopped coriander leaves<br />
Method<br />
Mix ½ tsp of the ground turmeric,<br />
with the salt and lime juice, rub into<br />
the fish steaks, then set aside. Add the<br />
onion, ginger and garlic to a blender<br />
and blend to a smooth fine paste with<br />
a splash of water. Set aside.<br />
Heat the oil in a heavy-based, nonstick<br />
saucepan over a medium heat.<br />
Add the mustard seeds and as they<br />
begin to sputter, work quickly to add<br />
the cardamom pods, green chillies<br />
and curry leaves. Add the onion,<br />
ginger and garlic paste and fry for 1–2<br />
mins, then add the remaining ground<br />
turmeric, along with the water, sugar<br />
and salt. Mix well, then simmer for 1<br />
min.<br />
Reduce the heat to low, then add<br />
the fish steaks and let them cook for<br />
a further minute. Add the coconut<br />
milk, cover and simmer gently for<br />
4–5 mins until the fish is moist and<br />
cooked through. Give the pan a gentle<br />
swirl a couple of times to make sure<br />
everything is mixed but the fish pieces<br />
don’t break up.<br />
Add the tamarind, black pepper<br />
and fresh coriander and stir well,<br />
simmering for 1 min. Serve with plain<br />
basmati rice and a cucumber salad.<br />
<strong>Optimum</strong> <strong>Nutrition</strong> tip:<br />
Try using ghee or coconut oil instead<br />
of vegetable oil, and swap white rice<br />
for wholegrain or cauliflower rice.<br />
How important is nutrition when<br />
serving a thali?<br />
“A lot of what gets served over a thali<br />
includes pulses, grains, dairy and even<br />
fresh fruit — ingredients that are high<br />
in protein, carbohydrates and rich in<br />
vitamins…<br />
“Thalis are a complete meal<br />
experience and brimming with<br />
vegetables, lentils, wholemeal breads and<br />
aromatic curries that bring warmth and<br />
flavour to our meals.”<br />
