Editorial<br />

Reflections<br />

On 29 May 2006, the 59th World<br />

Health Assembly, the governing<br />

body of the World Health<br />

Organization (WHO), adopted a<br />

resolution on the ‘Prevention of<br />

avoidable blindness <strong>and</strong> visual<br />

impairment’. Given that still more<br />

than 161 million people worldwide<br />

are visually impaired, of<br />

whom 37 million are blind, <strong>and</strong><br />

that about 75% of blindness is<br />

avoidable, the resolution is timely<br />

<strong>and</strong> is expected to strengthen<br />

the VISION 2<strong>02</strong>0 plans. VISION<br />

2<strong>02</strong>0: The Right to <strong>Sight</strong> is a<br />

global initiative of the WHO <strong>and</strong><br />

the International Agency for the<br />

Prevention of Blindness (IAPB).<br />

It comprises governments <strong>and</strong><br />

NGOs committed to the prevention<br />

<strong>and</strong> treatment of blindness.<br />

Among other things, the resolution<br />

urges member states to<br />

include Vision 2<strong>02</strong>0 in national<br />

development plans, <strong>and</strong> encourages<br />

partnerships between<br />

the public <strong>and</strong> private sectors,<br />

NGOs <strong>and</strong> communities. Since<br />

its inception SIGHT AND LIFE has<br />

supported IAPB, <strong>and</strong> now it has<br />

also become a formal partner of<br />

Vision 2<strong>02</strong>0. In this way SIGHT<br />

AND LIFE continues to take<br />

responsibility for the prevention<br />

of childhood blindness, as good<br />

vitamin A nutrition is pivotal for<br />

the eradication of this scourge.<br />

As indicated in the previous edition<br />

of the <strong>Newsletter</strong>, SIGHT<br />

AND LIFE’s 20th anniversary year<br />

will be a year of action. But after<br />

20 years of work committed to<br />

the fight against vitamin A <strong>and</strong><br />

other micronutrient deficiencies,<br />

this should also be a time for reflection.<br />

We think that we are on<br />

the right track with our mission<br />

<strong>and</strong> the services we provide, but<br />

I believe we could even do better.<br />

Therefore we are taking this occasion<br />

as an opportunity to examine<br />

our own activities. With the support<br />

of an international consultancy<br />

group we are determining<br />

how we can fully leverage our<br />

capabilities. The consultants are<br />

undertaking this project on a pro<br />

bono basis. Your feedback from<br />

the questionnaire (see <strong>Newsletter</strong><br />

1/2006) <strong>and</strong> interviews with some<br />

of you are a valued contribution<br />

towards this goal.<br />

Nutritional anemia remains an<br />

issue affecting more than two billion<br />

people worldwide. We have<br />

decided to bring together leading<br />

experts to discuss approaches<br />

to controlling nutritional anemia.<br />

The program of a corresponding<br />

workshop on 27 September<br />

2006 in Barcelona will be found<br />

on page 54 of this <strong>Newsletter</strong>.<br />

There is only limited capacity for<br />

the workshop <strong>and</strong> we are already<br />

almost fully booked. Should we,<br />

as we hope, succeed in moving<br />

the meeting to a larger room we<br />

will make an announcement to<br />

this effect on our website.<br />

On 16 June 2006, at the invitation<br />

of SIGHT AND LIFE, experts of<br />

the United Nations World Food<br />

Programme (WFP) came to Switzerl<strong>and</strong><br />

to discuss school feeding<br />

activities with employees of<br />

DSM Nutritional Products. There<br />

was an enormous interest in this<br />

topic. Micronutrient-enhanced<br />

school feeding in Madagascar is<br />

also the topic of a contribution<br />

to this <strong>Newsletter</strong> by Arnaud<br />

Laillou <strong>and</strong> coworkers (page 4).<br />

On page 25 you can read about<br />

the role of high-energy nutrient<br />

dense biscuits in the WFP’s<br />

tsunami response in South East<br />

Asia <strong>and</strong> school feeding. In April<br />

2006 a team from SIGHT AND<br />

LIFE visited Micronesia to shoot<br />

a film documentary on what is<br />

called by the United Nations<br />

St<strong>and</strong>ing Committee on Nutrition<br />

‘the double burden of malnutrition’.<br />

Under- <strong>and</strong> overnutrition<br />

can no longer be regarded in<br />

isolation – <strong>and</strong> early intervention<br />

is key in implementing successful<br />

preventative strategies. The<br />

purpose of the film is to create<br />

awareness <strong>and</strong> suggest solutions<br />

for this worldwide nutrition<br />

problem. Please read the article<br />

on page 39 by Lois Englberger<br />

<strong>and</strong> Adelino Lorens. Finally, I<br />

would like to call your attention to<br />

Barbara Underwood’s article on<br />

four decades of intense vitamin<br />

A <strong>and</strong> carotenoid research (page<br />

10). The article is based on the<br />

James Olson Memorial Lecture<br />

at this year’s Carotene Research<br />

Interaction Group (CARIG) annual<br />

conference (page 18). It is a very<br />

stimulating reflection on public<br />

health interventions to control<br />

vitamin A deficiency.<br />

I am convinced that this year’s reflections<br />

will provide us with clear<br />

directions for the future, <strong>and</strong>,<br />

more importantly, for the benefit<br />

of billions of people suffering from<br />

‘hidden hunger’.

Introduction<br />

The Nutrimad school feeding<br />

program (SFP), co-financed by<br />

SIGHT AND LIFE <strong>and</strong> the Ile<br />

de France regional council, is<br />

one of the three sections of the<br />

Nutrimad program, which is run<br />

by GRET (Research <strong>and</strong> Technological<br />

Exchange Group), the<br />

IRD (Institute of Research for<br />

Development), <strong>and</strong> the Labasan<br />

(Laboratory of Biochemistry Applied<br />

to the Food Sciences <strong>and</strong><br />

Nutrition, of the University of<br />

Antananarivo, Madagascar) with<br />

the aim of contributing to the sustainable<br />

reduction of malnutrition<br />

in Madagascar. The objectives<br />

of the program are to counter<br />

immediate hunger <strong>and</strong> school<br />

failure rates, <strong>and</strong> to respond to<br />

the nutritional deficiencies of children<br />

from public primary schools<br />

within the framework of a sustainable<br />

system of school snacks,<br />

overseen by the local authorities.<br />

The approach of the Nutrimad<br />

SFP was to introduce a snack<br />

that was accessible to everyone,<br />

i.e. inexpensive, made from local<br />

raw materials, liked by the<br />

children, readily obtainable <strong>and</strong><br />

reproducible, i.e. easy to prepare<br />

within schools, <strong>and</strong> of good nutritional<br />

value, i.e. designed so<br />

that one portion covers a share<br />

of nutritional requirements corresponding<br />

to the level of deficiencies<br />

generally observed in<br />

schoolchildren in Madagascar.<br />

The Nutrimad SFP was implemented<br />

during the 2004 – 2005<br />

school year in 15 public primary<br />

schools in underprivileged districts<br />

of Antananarivo, according<br />

to the methods described in a<br />

previous issue of the SIGHT AND<br />

LIFE <strong>Newsletter</strong> (1). The program<br />

comprised two parts.<br />

The first consisted in providing<br />

12,893 children from the 15<br />

schools with a snack in the form<br />

of a fortified <strong>and</strong> high-energy<br />

density gruel over an average of<br />

110 days (between 101 <strong>and</strong> 119,<br />

depending on the school) spread<br />

over a period of approximately<br />

6 months of the year.<br />

This gruel, which was served during<br />

the first break for the price of<br />

40 Ariary (approx 1.5 euro cents),<br />

was prepared in each school using<br />

a corn meal powder called<br />

“Koba Tsinjo” (72.6%), peanut<br />

(8.5%), sugar (14.0%) <strong>and</strong> a vitamin<br />

<strong>and</strong> mineral mixture, to which<br />

2.0% soybean oil was added during<br />

the preparation process. The<br />

quantities served (350 g of gruel<br />

containing 110 g of powder, or<br />

380 kcal) were sufficient to cover<br />

18% of the daily energy requirements<br />

of a 10-year-old child,

SIGHT AND LIFE<br />

as well as 75% of their RDA of<br />

micronutrients for which there is<br />

a major deficiency risk (iron, zinc<br />

<strong>and</strong> vitamin A), 60% of their RDA<br />

of calcium, 40% of their RDA of<br />

other minerals <strong>and</strong> vitamins, <strong>and</strong><br />

25% of their RDA of proteins,<br />

amino acids <strong>and</strong> essential fatty<br />

acids.<br />

The second part consisted in nutrition<br />

education activities, whose<br />

purpose was to communicate<br />

messages aimed at informing<br />

the pupils <strong>and</strong> encouraging them<br />

to adapt their diet to their nutritional<br />

requirements, <strong>and</strong> to lead a<br />

healthy lifestyle. These messages<br />

were delivered throughout the<br />

year by specially trained teachers,<br />

who were also provided with<br />

educational supports developed<br />

by the Nutrimad team.<br />

A first, still incomplete appraisal<br />

(presented to a meeting of national<br />

<strong>and</strong> international interest<br />

groups on 10 May 2006, at the invitation<br />

of Madagascar’s National<br />

Nutrition Office) of the operation<br />

<strong>and</strong> effects of the Nutrimad SFP<br />

during the 2004 – 2005 school<br />

year has now been drafted, <strong>and</strong><br />

this forms the basis of the present<br />

article.<br />

Methodological<br />

approach implemented<br />

for follow-up <strong>and</strong><br />

evaluation<br />

The follow-up <strong>and</strong> evaluation<br />

strategy implemented throughout<br />

the year 2004 – 2005 to check<br />

the relevance <strong>and</strong> effectiveness<br />

of the Nutrimad SFP consisted<br />

mainly in measuring:<br />

• pupils’ participation in the<br />

scheme<br />

• the effect of nutrition education<br />

activities on pupils’ nutrition<br />

knowledge<br />

• the effect of gruel consumption<br />

on the frequency <strong>and</strong> nature<br />

of pupils’ meals, on their nutritional<br />

status, <strong>and</strong> on their<br />

school performance<br />

In doing this, we had to take into<br />

account three main constraints.<br />

The first of these was the noninclusion<br />

of control schools in our<br />

evaluation strategy, which meant<br />

that we were limited to comparing<br />

indicator values either recorded<br />

at the beginning <strong>and</strong> end of the<br />

year with the same pupils, or<br />

calculated for groups of pupils<br />

put together according to their<br />

gruel consumption. The second<br />

constraint was the insufficiency<br />

of financial resources allocated<br />

to the evaluation studies, which<br />

limited our choice of indicators<br />

for impact on nutritional status to<br />

those based on anthropometric<br />

measurements. The third constraint<br />

was the impossibility of<br />

gathering, from the relevant services,<br />

previous years’ statistics on<br />

absenteeism <strong>and</strong> graduation into<br />

higher classes.<br />

The analyses carried out can be<br />

divided into three categories:<br />

• those carried out on the entire<br />

number (12,893) of pupils<br />

from 254 classes from the 15<br />

schools, which consisted in<br />

creating a typology of schools<br />

<strong>and</strong> in recording information<br />

on the classes <strong>and</strong> teachers,<br />

as well as a self-administered<br />

questionnaire survey of the<br />

socio-economic situation of<br />

the families, a daily record of<br />

information on absenteeism<br />

<strong>and</strong> consumption of the snacks,<br />

anthropometric measurements<br />

<strong>and</strong> tests of nutrition knowledge<br />

taken at the beginning <strong>and</strong> end<br />

of the school year, <strong>and</strong> a record<br />

of results from the end-of-year<br />

exam determining whether<br />

pupils graduate into higher<br />

classes <strong>and</strong> which academic<br />

direction they should take;


SIGHT AND LIFE 6<br />

NEWSLETTER 2/2006<br />

• those carried out on reduced<br />

samples of pupils, in particular<br />

a measurement of food-intake<br />

which allowed us to check the<br />

adequacy of the consumption<br />

of gruel actually served (2,573<br />

pupils from 64 classes in 5<br />

schools), serial data-gathering<br />

intended to estimate, amongst<br />

other things, the effects of<br />

gruel consumption on the<br />

frequency <strong>and</strong> composition of<br />

meals (all pupils from 5 of the<br />

15 schools), <strong>and</strong> the share of<br />

nutritional requirements covered<br />

(a survey based on recall<br />

of the past 24 hours carried out<br />

on 480 children from 9 of the<br />

15 schools);<br />

• finally, studies concerning gruel<br />

preparation, which were carried<br />

out in 5 schools to ensure<br />

that preparation guidelines<br />

were being respected <strong>and</strong> to<br />

check the characteristics of the<br />

gruel being served.<br />

Confirmation of the poor<br />

nutritional status <strong>and</strong><br />

low spending power of<br />

pupils<br />

In the first place, the surveys <strong>and</strong><br />

measurements taken allowed us<br />

to confirm the poor nutritional<br />

status of pupils at the start of the<br />

school year, before the Nutrimad<br />

SFP was launched.<br />

Delayed growth <strong>and</strong> low weight<br />

affected 46.0% <strong>and</strong> 32.8% of<br />

Figure 1. Prevalence of delayed<br />

growth, wasting, <strong>and</strong> low weight<br />

in children from the 15 schools (the<br />

figures for wasting are for children<br />

under 10 only).<br />

children respectively, although<br />

there was a low prevalence<br />

(2.2%) of wasting among children<br />

under 10 years (Figure 1).<br />

Moreover, the nutritional status<br />

of boys is noticeably worse than<br />

that of girls (49.6% vs. 42.2%<br />

for delayed growth; 37.8% vs.<br />

27.3% for low weight), <strong>and</strong>, while<br />

the prevalence of malnutrition remains<br />

relatively constant between<br />

ages 6 <strong>and</strong> 10, it increases considerably<br />

in older children. Furthermore,<br />

it seems that there is an<br />

important relationship between<br />

academic underachievement<br />

<strong>and</strong> nutritional status insofar as,<br />

of the total number of children,<br />

the prevalence of arrested size<br />

fits 38% of children who are one<br />

school year behind, <strong>and</strong> 55% of<br />

children who are two school years<br />

behind in their studies.<br />

Regarding the sums of money the<br />

children could afford to spend on<br />

food each day, the 11,255 children<br />

who completed the questionnaire<br />

had received an average<br />

of 67 Ariary from their parents on<br />

their most recent day at school.<br />

A third of the children received<br />

more than 50 Ariary, while 27%<br />

received less, of whom 5.1%<br />

received nothing at all.<br />

A high rate of pupil<br />

participation in the<br />

scheme<br />

Over the entire gruel distribution<br />

period, the average rate of pupil<br />

participation in the scheme, i.e.<br />

the average percentage of days<br />

on which they consumed at least<br />

one serving of gruel during the<br />

operational period of the Nutrimad<br />

SFP, was 68.4%. This rate<br />

was slightly higher in the second<br />

semester (71%) than in the other<br />

two (67% <strong>and</strong> 66%). The older the<br />

children, the more their participation<br />

rate went up (from 60% at age<br />

6 to 77% at age 13), or in other<br />

words, participation increased in<br />

direct proportion with the level of<br />

the school year (Figure 2).<br />

Ultimately, despite having to pay<br />

40 Ar for each serving of gruel,<br />

34.3% of pupils took over 80% of<br />

the opportunities offered them to<br />

eat it throughout the year, which<br />

means that only 9.6% took 20%<br />

or less of these opportunities.

SIGHT AND LIFE<br />

Gruel prepared <strong>and</strong><br />

consumed according to<br />

recommendations<br />

The observations <strong>and</strong> samples<br />

taken have shown that gruel<br />

prepared in the schools did indeed<br />

contain on average the<br />

desired concentration of energy<br />

(108 kcal/100 g of gruel, which<br />

corresponds to 378 kcal for a<br />

350 g serving) <strong>and</strong>, moreover, that<br />

94.1% of children completely finished<br />

their plate of gruel, with only<br />

0.75% of children leaving more<br />

than 4 soup-spoonfuls, <strong>and</strong> 2.9%<br />

sharing their gruel with a friend.<br />

Under these conditions, we can<br />

calculate that, over the 6 month<br />

period (from November 2004<br />

to May 2005) during which the<br />

Nutrimad SFP was in operation,<br />

the snacks provided 23.8% of the<br />

children with over 40% of their<br />

RDA in micronutrients for which<br />

there is a major deficiency risk,<br />

between 20% <strong>and</strong> 40% of the<br />

RDA for 65% of them, <strong>and</strong> under<br />

20% for only 11.2%.<br />

A snack which does not<br />

take the place of regular<br />

meals<br />

Pending the processing of data<br />

from the survey based on recall of<br />

the past 24 hours, which should<br />

allow us to compare percentages<br />

of nutritional cover between<br />

children who ate the snacks <strong>and</strong><br />

those who did not, the results<br />

provided here concern the effect<br />

of snack consumption on the<br />

frequency of daily meals.<br />

The consumption of breakfasts<br />

(96.3%) <strong>and</strong> lunches (95.7%) at<br />

home by the children was just as<br />

frequent among those who ate<br />

the snacks as it was among those<br />

who did not. The consumption<br />

of dinners was even slightly, but<br />

significantly (98.1% vs. 96.1%;<br />

Improved nutrition<br />

knowledge <strong>and</strong><br />

awareness<br />

The average marks obtained<br />

from nutrition knowledge tests<br />

taken before <strong>and</strong> after the Nutrimad<br />

SFP’s 6-month operation<br />

period are given in Figure 5. For<br />

all the school years there was a<br />

significant improvement of nutrition<br />

knowledge during the year,<br />

although this improvement is<br />

apparently greater in years CP2,<br />

CP1 <strong>and</strong> CE than in CM1 <strong>and</strong><br />

CM2.<br />

The statistical analyses led to<br />

the identification of certain factors<br />

influencing the variations<br />

in pupils’ nutrition knowledge<br />

throughout the school year. The<br />

most important of these, taking<br />

into account the essential role<br />

played by the communication<br />

of messages, was the teachers’<br />

motivation.<br />

to gruel consumption: 1) less than<br />

20%; 2) 20% to 40%; 3) over 40%.<br />

*Adjusted by analysis of covariance for<br />

characteristics of the teachers, of the<br />

children’s family group (index of possessions,<br />

number of siblings, amount of<br />

pocket money given them by their parents)<br />

the start of the year (age, size, Size/age<br />

<strong>and</strong> Weight/age Z-scores)<br />

knowledge tests at the beginning <strong>and</strong> end of the school year (CP–CM2<br />

Impact on school<br />

performance<br />

An assessment of the effect of<br />

snack consumption on school<br />

performance of the total number<br />

of pupils from the 15 schools was<br />

based on the decision made at<br />

the end of the year as to whether<br />

they should graduate to the next<br />

class, <strong>and</strong> on the marks they<br />

obtained at the end-of-year exams.<br />

The children from group 3 were<br />

over 10% more likely to be allowed<br />

to graduate to the next<br />

class than those from group 1<br />

(81% vs. 71%). Moreover, they<br />

were 6% less likely than group 1<br />

to obtain below average marks<br />

at the end-of-year exams (27.1%<br />

Conclusion<br />

The follow-up <strong>and</strong> evaluation<br />

of the Nutrimad SFP during the<br />

2004 – 2005 school year has essentially<br />

allowed us to highlight<br />

the poor nutritional status of children<br />

<strong>and</strong> to establish, or highlight,<br />

the adequacy of the type of snack<br />

provided:<br />

• over the 110 days of the program,<br />

the children took 68%<br />

of opportunities offered them<br />

to eat the gruel;<br />

• each portion consumed covered<br />

16% to 22% of their energy<br />

requirements <strong>and</strong> 75% of<br />

their requirements of the main<br />

micronutrients;<br />

• the snacks did not take the<br />

place of regular meals.<br />

Furthermore, at the end of the<br />

year the most regular consumers<br />

had, in comparison with the<br />

others, a better nutritional status<br />

(40% vs. 50% delayed growth),<br />

were less likely to have to repeat<br />

their school year (20% vs. 30%),<br />

<strong>and</strong> did better at the end-of-year<br />

exams.<br />

These very encouraging results<br />

are currently undergoing confirmation<br />

in the 2005 – 2006 period<br />

at the same schools. The integration<br />

of 8 control schools into the<br />

evaluation process should allow<br />

us to highlight not only the effect<br />

of snack consumption <strong>and</strong> nutrition<br />

education on the children’s<br />

nutritional status <strong>and</strong> school<br />

performance, but also the effectiveness<br />

of the present strategy<br />

within the context of the education<br />

system concerned.<br />

Reflections: Four decades with vitamin A <strong>and</strong><br />

carotenoids; James Allen Olsen Memorial Lecture, CARIG, 2006<br />

Barbara A Underwood* 1 , PhD, Adjunct Professor of Nutrition, Institute of Human<br />

Nutrition, Columbia University, New York<br />

Introduction<br />

James Allen Olson was a biochemist/nutrition<br />

scientist, mentor,<br />

colleague <strong>and</strong> friend to many<br />

of us. He was the father of VARIG<br />

(Vitamin A Research Interactive<br />

Group) <strong>and</strong> CARIG (Carotenoid<br />

Research Interactive Group) at<br />

the Experimental Biology meetings<br />

<strong>and</strong> one of the founding<br />

members of IVACG (International<br />

Vitamin A Consultative Group). At<br />

IVACG he was frequently requested<br />

to provide updates on vitamin<br />

A <strong>and</strong> carotenoid metabolism<br />

<strong>and</strong> he carried the torch for foodbased<br />

approaches to vitamin A<br />

deficiency as a vital component<br />

of any micronutrient control program.<br />

For many years Jim <strong>and</strong><br />

I worked together within IVACG<br />

<strong>and</strong> as research colleagues in<br />

vitamin A metabolism, assessment<br />

of status <strong>and</strong> promotion<br />

of sustainable intervention programs.<br />

It is a privilege <strong>and</strong> an<br />

honor to be asked to speak at this<br />

memorial lecture <strong>and</strong> to reflect<br />

back to some of the significant<br />

years in vitamin A <strong>and</strong> carotenoid<br />

research <strong>and</strong> programs.<br />

then?* 2<br />

In 1960, Hoffmann-LaRoche organized<br />

CD; editor.<br />

P. Karrer (1). Karrer had isolated<br />

<strong>and</strong> elucidated the structure of<br />

vitamin A in 1931. The content<br />

of the symposium was meant to<br />

sum-up the situation with respect<br />

to vitamin A <strong>and</strong> provitamin A<br />

carotenoids. The “sum-up” revealed<br />

that there was yet lots to<br />

be learned, despite the fact that<br />

deficiency eye symptoms were<br />

described <strong>and</strong> a cure known<br />

(liver extract) from ancient times<br />

(2); that in the second decade<br />

of the 20th century these symptoms<br />

were attributed to lack of<br />

a fat-soluble substance found in<br />

some animal foods <strong>and</strong> butterfat<br />

(3,4), which McCollum named<br />

vitamin A (3), or to a lack of carotenoids<br />

in some plant foods that<br />

Steenbock suggested in 1919<br />

could be converted to the active<br />

component (5); that vitamin A<br />

was isolated <strong>and</strong> its structure<br />

elucidated by Karrer in 1931<br />

(6); that Wald <strong>and</strong> colleagues in<br />

the latter part of the1930s had<br />

uncovered the functional role of<br />

the vitamin in vision (7,8); <strong>and</strong> in<br />

1960, that Dowling <strong>and</strong> Wald (9)<br />

had reviewed the overt systemic<br />

signs of vitamin A deficiency <strong>and</strong><br />

the role of vitamin A acid (retinoic<br />

acid) in maintaining growth <strong>and</strong><br />

the health of epithelial tissues,<br />

though animals were deficient<br />

in retinol <strong>and</strong> were night-blind.<br />

And importantly, Stephenson<br />

<strong>and</strong> Clark* 3 as early as 1920 reported<br />

that rats fed diets void of<br />

the active fat-soluble substances<br />

died at a higher rate even before<br />

eye signs occurred, but that eye<br />

symptoms in every case cleared<br />

when a petroleum ether extract<br />

of dried carrot was incorporated<br />

into their diet (10).<br />

In spite of all that was known by<br />

1960, much remained unknown.<br />

There was little knowledge of<br />

the global magnitude of the<br />

deficiency problem in humans.<br />

In part this was because there<br />

was no consensus on how best<br />

to assess vitamin A deficiency<br />

either clinically or biochemically<br />

given that clinical signs were not<br />

st<strong>and</strong>ardized <strong>and</strong> methodologies<br />

available for biochemical<br />

assessment provided uncertain<br />

results. Detailed information on<br />

the metabolism of vitamin A was<br />

limited <strong>and</strong> the active form <strong>and</strong><br />

function of vitamin A outside the<br />

visual cycle was still speculative<br />

(11). Analytical methods for quantitative<br />

analysis existed for both<br />

the preformed vitamin <strong>and</strong> for<br />

provitamin carotenoids, but these<br />

methods were often tedious, difficult<br />

to st<strong>and</strong>ardize, <strong>and</strong> frequently<br />

used toxic chemicals that failed<br />

to provide reproducible results in<br />

many laboratories (12–14). There<br />

were no large-scale intervention<br />

programs to combat vitamin A<br />

deficiency <strong>and</strong> even at the local<br />

level within hospitals there was<br />

little appreciation of how to treat<br />

or prevent the deficiency, which<br />

often accompanied proteinenergy<br />

malnutrition (PEM). And<br />

notably, there was very little political<br />

interest or will to eliminate<br />

vitamin A deficiency.<br />

I saw my first cases of xerophthalmia<br />

in 1961, more than four<br />

decades ago, while conducting<br />

doctoral research among refugee<br />

children in what was then Jerusalem,<br />

Jordan. I was midway<br />

through studies at Columbia<br />

University Institute of Nutrition<br />

Sciences, later renamed the Institute<br />

of Human Nutrition (IHN).<br />

I went there in 1959 because of<br />

a deep concern for problems of<br />

childhood malnutrition in the developing<br />

world <strong>and</strong> the desire to<br />

become professionally involved<br />

in seeking appropriate solutions.<br />

The Institute had a newly created<br />

program led by William Henry<br />

Sebrell, one of the pioneer nutritionists<br />

of the 20th century. The<br />

Institute’s objective was to train<br />

students to analyze, underst<strong>and</strong><br />

<strong>and</strong> seek solutions to malnutrition<br />

in the developing world in a holistic<br />

context (15). My academic<br />

training within this environment<br />

<strong>and</strong> the opportunity to do my<br />

thesis research in an international<br />

setting among malnourished children<br />

set the tone for the rest of<br />

my professional career.<br />

2006: Where are we<br />

today – after 4½<br />

decades?<br />

Prevalence<br />

No doubt, we have a greater<br />

appreciation of the magnitude<br />

of the global problem <strong>and</strong> the<br />

epidemiological factors, in addition<br />

to diet, that contribute to<br />

its existence. The Micronutrient<br />

Report published in 2001(16)<br />

placed the magnitude of the<br />

problem among preschool-aged<br />

children at 75 – 140 million; earlier<br />

estimates by the WHO placed the<br />

prevalence as high as 230 million<br />

(17). These prevalence data are<br />

based on clinical eye signs <strong>and</strong>/or<br />

low blood vitamin A levels from a<br />

database that is far from representative<br />

<strong>and</strong> firm. Nonetheless,<br />

The Micronutrient Report also<br />

noted a trend toward improvement<br />

since 1980 in most regions<br />

of the world, particularly since<br />

1990, a period when large-scale<br />

periodic vitamin A distribution programs<br />

were exp<strong>and</strong>ing. Indeed,<br />

on the public health level, intervention<br />

by periodic distribution<br />

of high-dose vitamin A supplements<br />

now covers an estimated<br />

70% of preschool-aged children<br />

in 40 countries with at least one<br />

dose of vitamin A annually, <strong>and</strong><br />

about 1/3 of these 40 countries<br />

have achieved 70% coverage<br />

with the required two doses (18).<br />

However, now we know that the<br />

problem extends beyond the preschool<br />

years to pregnant women<br />

whose health <strong>and</strong> survival also are<br />

compromised in countries where<br />

deficiency is common (19). The<br />

magnitude of deficiency among<br />

pregnant women, however, is<br />

largely unknown <strong>and</strong> there are few<br />

targeted prevention programs in<br />

effect that reach these vulnerable<br />

women.<br />

Metabolism <strong>and</strong> methods<br />

Knowledge of the metabolism of<br />

vitamin A <strong>and</strong> carotenoids has<br />

advanced dramatically since<br />

1960. The active forms <strong>and</strong> functions<br />

of vitamin A are established:<br />

retinol in the visual system <strong>and</strong><br />

retinoic acid in normal growth<br />

<strong>and</strong> development by modulation<br />

of gene actions. And new knowledge<br />

of non-provitamin A roles of<br />

carotenoids in the moderation of<br />

degenerative diseases is evolving<br />

as definitive analytical techniques<br />

allow for tracing the metabolism<br />

of individual carotenoids. Quantitative<br />

analytical methods for<br />

retinoids are well advanced (20)<br />

<strong>and</strong> this has contributed to a<br />

variety of new field assessment<br />

methods, including a more objective<br />

(dry blood spots) for subsequent<br />

quantitative analysis either in the<br />

field or at a base laboratory (22)<br />

<strong>and</strong> assessing whole body stores<br />

(isotope dilution) (23). The application<br />

of new intrinsic carotenoid<br />

labeling methods offers greater<br />

ability to trace individual carotenoids<br />

from vegetables containing<br />

them in their natural matrices to<br />

their uptake from the gut <strong>and</strong> utilization:<br />

hence, to a more accurate<br />

measure of bioavailability (24).<br />

Programs<br />

Intervention programs are moving<br />

beyond strictly distributing<br />

nutrient supplements. These<br />

programs are becoming more<br />

integrated <strong>and</strong> viewed more<br />

holistically within the context of<br />

undernutrition, underdevelopment<br />

<strong>and</strong> poverty. Micronutrient<br />

fortified foods that can address<br />

both specific deficiencies <strong>and</strong> caloric<br />

undernutrition are available<br />

in many countries. They include<br />

vitamin A fortified sugar, oils, <strong>and</strong><br />

some cereals, to name a few, but<br />

access by the poor at greatest<br />

risk still varies greatly, especially<br />

in rural areas with limited market<br />

access. And public health measures<br />

including promotion <strong>and</strong><br />

support for breastfeeding, exp<strong>and</strong>ed<br />

immunization coverage,<br />

parasite control programs, <strong>and</strong><br />

home-based control of severe diarrheal<br />

disease have contributed<br />

to decreased infectious morbidity<br />

<strong>and</strong> mortality <strong>and</strong>, hence,<br />

development. Although improvements<br />

are occurring in availability<br />

of potable water <strong>and</strong> environmental<br />

sanitation, the UN reports<br />

(Los Angeles Times, March 10)<br />

that over 1.1 billion living in impoverished<br />

communities remain<br />

without safe water. Yet in spite of<br />

all the progress made, including<br />

distribution of over 400 million<br />

vitamin A capsules annually (18),<br />

vitamin A deficiency remains a<br />

significant public health problem.<br />

A diet inadequate in vitamin A-<br />

containing food sources is the<br />

underlying cause of deficiency.<br />

Yet until recently food-based approaches<br />

that impact on underlying<br />

causes of underdevelopment,<br />

undernutrition <strong>and</strong> micronutrient<br />

deficiencies were the step-child<br />

intervention least attractive to<br />

international funding agencies.<br />

How did we get from<br />

there (1960) to here<br />

(2006)? Some significant<br />

decade milestones<br />

1960–1970: Progress<br />

in underst<strong>and</strong>ing basic<br />

metabolism<br />

The decade of the 1960s was the<br />

period that in my reflective view<br />

was noted mostly for advances in<br />

underst<strong>and</strong>ing the basic metabolism<br />

of vitamin A <strong>and</strong> provitamin A<br />

carotenoids. Central cleavage of<br />

beta-carotene in James Olson’s<br />

(25) <strong>and</strong> DeWitt Goodman’s (26)<br />

laboratories by enzymes isolated<br />

from the gut <strong>and</strong> liver of rats advanced<br />

knowledge of bioconversion<br />

mechanisms. In humans,<br />

efficient uptake of dietary retinol<br />

<strong>and</strong> conversion of β-carotene to<br />

retinal, esterification to retinyl<br />

esters, transport of the esterified<br />

product in lymph chylomicra <strong>and</strong><br />

hepatic uptake from chylomicra<br />

remnants were demonstrated (27).<br />

Retinol binding protein (RBP) was<br />

isolated <strong>and</strong> partially characterized<br />

in 1968, <strong>and</strong> subsequently<br />

its role in hepatic mobilization <strong>and</strong><br />

transport of retinol as holo-RBP<br />

complexed with transthyretin was<br />

defined (28). Underst<strong>and</strong>ing of<br />

the reversible formation of single,<br />

bi- <strong>and</strong> trimolecular complexing<br />

clarified how the exchange<br />

of retinol from blood to tissues<br />

occurred without loss through<br />

kidney filtration. Furthermore, the<br />

concepts revealed in defining the<br />

metabolism of RBP provided the<br />

basis in the following two decades<br />

for a new indirect assessment of<br />

depleted hepatic stores, the relative<br />

dose response (RDR) in my<br />

laboratory (29), its modification<br />

(MRDR) in James Olson’s laboratory<br />

(30) <strong>and</strong> its current broad use<br />

in assessment of vitamin A status<br />

in human <strong>and</strong> animal studies.<br />

On the public health front progress<br />

was slow. In 1964 the first ‘guestimate’<br />

of the global magnitude<br />

of deficiency was made. The approximation<br />

of 20,000 to 100,000<br />

affected children was based<br />

largely on interviews <strong>and</strong> subjective<br />

information on the prevalence<br />

of eye signs (31), which did not<br />

generate political support for<br />

large intervention programs, even<br />

though severe vitamin A deficiency<br />

in children was very evident in<br />

developing countries, often associated<br />

with PEM, <strong>and</strong> too often<br />

inappropriately managed leading<br />

to irreversible blindness, if the patient<br />

survived. Many of us involved<br />

in international child health issues<br />

during the 1960s were appalled<br />

by the lack of attention to this<br />

preventable public health scourge,<br />

but there was no organized group<br />

to champion the cause at a political<br />

level <strong>and</strong> attract substantial<br />

funds for prevention.

Donald S McLaren<br />

1970–1980: Breakthroughs<br />

in analytical methodology<br />

<strong>and</strong> public health<br />

The decade of the 1970s is<br />

noteworthy for a major methodological<br />

breakthrough in retinoid<br />

analyses, the application of highpressure<br />

liquid chromatography<br />

(HPLC). Harold Furr recently<br />

commented that “Progress in nutritional<br />

biochemistry has always<br />

depended on progress in analysis<br />

of nutrients” (20). That is why the<br />

advent of HPLC in the mid-1970s<br />

was such an important addition<br />

to the analytical assessment<br />

arsenal (32,33), opening doors<br />

for progress in both basic <strong>and</strong><br />

applied research. Although the<br />

instrument originally was too<br />

expensive to obtain <strong>and</strong> maintain<br />

in developing countries, it is now<br />

broadly available <strong>and</strong> the method<br />

of choice for most applications<br />

requiring quantitative retinoid<br />

analyses, especially for the analysis<br />

of vitamin A in blood.<br />

On the public health platform<br />

during the 1970s, the most important<br />

advance in vitamin A<br />

program applications occurred as<br />

the result of three seminal meetings.<br />

The first was a WHO/USAID<br />

sponsored meeting in Jakarta,<br />

Indonesia in 1974 (34). The Jakarta<br />

meeting was notable for<br />

the heated controversy between<br />

ophthalmologists, epidemiologists<br />

<strong>and</strong> nutritional biochemists<br />

on the appropriate classification<br />

criteria for xerophthalmia, cut-off<br />

points to establish a public health<br />

problem, the health consequences<br />

of deficiency beyond the eye,<br />

reliable assessment methodology<br />

<strong>and</strong> efficacy <strong>and</strong> effectiveness of<br />

different intervention programs.<br />

Tentative decisions on these<br />

issues were published in the<br />

meeting report but the science<br />

base was weak <strong>and</strong> few were<br />

satisfied. The scientists went<br />

from this meeting determined<br />

to provide the missing research<br />

data to resolve disagreements<br />

(35). The following year (1975)<br />

IVACG was formally established<br />

to maintain momentum toward<br />

the control of vitamin A deficiency<br />

diseases by providing an<br />

annual forum (later changed to<br />

biannual meetings) for information<br />

exchange among researchers,<br />

public health professionals,<br />

international funding agencies,<br />

non-governmental agencies <strong>and</strong><br />

private industry (36). Research<br />

activities did accelerate in subsequent<br />

years as was obvious in the<br />

follow-up WHO/UNICEF/USAID/<br />

HKI/IVACG-sponsored meeting in<br />

Jakarta in 1980 (37). The meeting<br />

was less controversial because<br />

data were available from the<br />

considerable amount of research<br />

that had been completed in the<br />

previous six years. The result was<br />

consensus on earlier arguable<br />

issues, i.e. st<strong>and</strong>ardization <strong>and</strong><br />

classification of xerophthalmia<br />

symptoms <strong>and</strong> signs, treatment<br />

<strong>and</strong> prophylaxis schedules <strong>and</strong><br />

agreement to draw attention to<br />

the need for large-scale intervention<br />

programs.<br />

Creation of IVACG deserves special<br />

mention. The USAID established<br />

<strong>and</strong> sponsored the group<br />

for 30 years. Administration of<br />

the program initially was through<br />

the Nutrition Foundation, which<br />

was later transformed into the<br />

International <strong>Life</strong> Science Institute<br />

(ILSI). The group began with<br />

only 17 committed individuals<br />

<strong>and</strong> reached as many as 100 over<br />

the first decade (36). Individuals<br />

worked voluntarily in task forces<br />

Alfred Sommer<br />

between the annual meetings to<br />

produce guidelines <strong>and</strong> state-ofthe-art<br />

reviews, many of which<br />

remain useful even today. James<br />

Olson was a charter member of<br />

IVACG <strong>and</strong> co-authored many<br />

of the guidelines <strong>and</strong> reviews.<br />

He seldom missed a meeting.<br />

Frequently he provided the biochemical<br />

updates because his<br />

presentations were so lucid <strong>and</strong><br />

underst<strong>and</strong>able by all in the<br />

diverse group that assembled<br />

annually. In addition, he usually<br />

chaired sessions on carotenoid<br />

biochemistry <strong>and</strong> conducted focus<br />

groups on carotenoids <strong>and</strong><br />

food-based issues. The meetings<br />

grew during the three decades of<br />

IVACG’s existence to an attendance<br />

of about 800 delegates at the<br />

22nd meeting held in Lima, Peru<br />

in 2004. The 2004 meeting was<br />

the last before disb<strong>and</strong>ment <strong>and</strong><br />

reorganization, which is currently<br />

in progress, to form a Micronutrient<br />

Forum. IVACG during its 30<br />

years of existence gained respect<br />

throughout the international community<br />

<strong>and</strong> played an influential<br />

role in international programs to<br />

control deficiency world-wide.<br />

Hopefully the reformed Forum<br />

will continue the momentum of<br />

IVACG in influencing scientific<br />

directions <strong>and</strong> political decisions,<br />

hence accelerating the elimination<br />

of micronutrient deficiencies<br />

as public health problems.

1980–1990: Retinoid<br />

revolution in the lab <strong>and</strong><br />

recognition that ocular<br />

signs were the tip of the<br />

iceberg in the field<br />

Retinoid biochemistry experienced<br />

a renaissance late in the<br />

century when nuclear retinoid<br />

receptors were identified <strong>and</strong><br />

their pleiotrophic effects recognized<br />

in 1987 (38). This was the<br />

beginning of research that has<br />

identified how retinoic acid influences<br />

a multitude of gene actions<br />

that regulate differentiation <strong>and</strong><br />

cellular growth <strong>and</strong> functions.<br />

This revolution is on-going with<br />

new effects on functions being<br />

reported regularly.<br />

On the public health scene,<br />

though nutritional biochemists<br />

had argued vehemently at the<br />

1974 meeting in Jakarta that<br />

health consequences went far<br />

beyond the eye-based on animal<br />

studies – ophthalmologists were<br />

unconvinced. The data systematically<br />

collected in Indonesia<br />

by Alfred Sommer (an ophthalmologist/epidemiologist)<br />

<strong>and</strong><br />

colleagues during the decade of<br />

the 1980s documented the prevalence<br />

of vitamin A deficiency in<br />

the country <strong>and</strong> provided a firmer<br />

basis for projecting the extent of<br />

the problem in four other Asian<br />

countries, i.e. 200,000–400,000<br />

corneal cases <strong>and</strong> 4–8 million<br />

non-corneal cases (39). The team<br />

also elucidated the underlying<br />

epidemiological associations that<br />

led to clustering of deficiency in<br />

affected populations. The epidemiologic<br />

studies associated the<br />

lack of diversity in child diets,<br />

including lack of animal products<br />

<strong>and</strong> carotenoid-containing fruits<br />

<strong>and</strong> vegetables, with deficiency.<br />

The survey <strong>and</strong> epidemiological<br />

studies set the stage for the large<br />

r<strong>and</strong>omly designed, controlled<br />

intervention trial that first established<br />

in humans the mortality<br />

risk associated with deficiency<br />

(40,41) that six decades earlier<br />

had been reported in animals<br />

(10). The announcement at an<br />

IVACG meeting late in the 1980s<br />

of a 27% reduction in mortality<br />

was met with skepticism by the<br />

scientific community, including<br />

myself, who found it difficult to<br />

believe that such a large effect<br />

could occur from supplementation<br />

without also addressing the<br />

prevalence of other diseases<br />

<strong>and</strong> unsanitary environmental<br />

conditions. Subsequently preschool<br />

child mortality associated<br />

with deficiency was confirmed,<br />

though variable in magnitude,<br />

in Nepal (42), in Ghana (43), <strong>and</strong><br />

in India (44), but not in Sudan<br />

(45), after administering highdose<br />

vitamin A capsules every<br />

4 or 6 months. Child mortality<br />

was also reduced in Indonesia<br />

(46) by regular intake of fortified<br />

monosodium glutamate, <strong>and</strong> in<br />

India (47) by providing a low-dose<br />

weekly supplement, potentially<br />

obtainable through food sources.<br />

Meta-analyses using data from<br />

the major trials concluded that<br />

on average, a 23–30% increase<br />

in mortality is associated with<br />

deficiency (48-50).<br />

1990–2000: Progress on the<br />

political front<br />

Political progress marked the<br />

decade of the 1990s. UNICEF’s<br />

World Summit for Children in 1990<br />

was the ideal situation to call attention<br />

to the striking mortality reduction<br />

benefit expected by correcting<br />

vitamin A deficiency. All<br />

the ingredients were assembled<br />

to launch a major international<br />

offensive against the deficiency<br />

as a public health scourge. The<br />

mortality risk was established<br />

<strong>and</strong> a short-term cost-effective<br />

intervention was available in<br />

the form of high-dose vitamin A<br />

supplements. A persuasive, passionate,<br />

committed champion in<br />

the person of James Grant, then<br />

director of UNICEF, was poised to<br />

effectively mobilize the high-level<br />

political commitment needed<br />

from member states to launch<br />

a major international offensive.<br />

This broad political commitment<br />

was achieved. The commitments<br />

were reinforced at subsequent<br />

international meetings in Canada<br />

in 1991, sponsored by several<br />

bilateral <strong>and</strong> international groups,<br />

at the International Conference<br />

on Nutrition in 1992, sponsored<br />

by WHO/FAO <strong>and</strong> in 1996 at the<br />

WHO/FAO World Food Summit<br />

in Rome. The emphasis from the<br />

beginning was on exp<strong>and</strong>ing the<br />

distribution of high-dose vitamin A<br />

supplements. Little support was<br />

available for alternative strategies.<br />

Supplement distribution<br />

was greatly facilitated when, in<br />

the latter part of 1990, distribution<br />

was linked to the WHO Exp<strong>and</strong>ed<br />

Program of Immunization’s (EPI)<br />

initiative of National Immunization<br />

Days (NID) for eradication<br />

of polio. This initiative provided<br />

a contact with preschool-aged<br />

children with minimal additional<br />

resources for delivery of the vitamin<br />

A capsule <strong>and</strong> is credited<br />

with success in greatly exp<strong>and</strong>ing<br />

coverage. NIDs have now ceased<br />

<strong>and</strong> countries are finding alternative<br />

mechanisms for sustaining<br />

the high coverage rates.<br />

Food fortification in developing<br />

countries received minor attention<br />

until midway in the decade,<br />

in spite of the successful fortification<br />

of sugar in Central America<br />

(51). Primitive development of<br />

the food industry <strong>and</strong> absence of<br />

regulatory controls were considered<br />

deterrents. But the need for<br />

a more sustainable intervention<br />

than periodic supplementation<br />

was recognized. The initiative<br />

for universal fortification of salt<br />

with iodine was making great<br />

inroads into relieving iodine deficiency<br />

disorders in developing<br />

countries, even in remote areas.<br />

Salt iodination advocates pushed<br />

their success as a model for vitamin<br />

A fortification, even though<br />

no comparable universally safe<br />

<strong>and</strong> acceptable food vehicle for<br />

vitamin A was available. Today, as<br />

noted earlier, there is momentum<br />

behind vitamin A fortification pro-

grams using several food vehicles<br />

adapted to cultural consumption<br />

habits, such as oils, cereals,<br />

condiments <strong>and</strong> dairy products.<br />

Because supplements in the form<br />

of vitamin A or β-carotene in doses<br />

similar to the RDA but given<br />

weekly reduced maternal mortality<br />

by 40–50% (19), comparable<br />

results could be expected by<br />

appropriately fortifying commonly<br />

eaten foods incorporated into a<br />

diversified diet (52).<br />

Lip-service, but few resources,<br />

were devoted to food-based<br />

interventions through the 1990s,<br />

despite the fact that vitamin A<br />

deficiency as a public health<br />

problem is due to an inadequate<br />

diet. Horticultural or other agricultural<br />

approaches attracted<br />

minimal international funding<br />

support <strong>and</strong>, therefore, potential<br />

for food-based approaches was<br />

not adequately evaluated (53). In<br />

part this can be attributed to the<br />

debate in recent years over bioavailabilty<br />

of provitamin-A carotenoid<br />

food sources, particularly<br />

green leafy vegetables that had<br />

been promoted for many years.<br />

The late Clive West introduced<br />

the controversy at a meeting of<br />

the Sub-Committee on Nutrition<br />

in Canada where he suggested<br />

that the 6:1 bioefficacy factor for<br />

beta-carotene used to evaluate<br />

food sources vastly overestimated<br />

its true value. Though the<br />

6:1 factor was vigorously debated<br />

<strong>and</strong> defended, subsequent studies<br />

by the West group (54) <strong>and</strong><br />

others upheld the claim for a<br />

less efficient conversion factor<br />

<strong>and</strong> forced reevaluation of food<br />

sources of carotenoids, particularly<br />

as contenders for elimination<br />

of vitamin A deficiency. In my<br />

view, the debate virtually closed<br />

off international support for horticultural-based<br />

intervention programs<br />

in the decade of the1990s<br />

in spite of the success of the<br />

large-scale horticultural initiative<br />

in Bangladesh, sponsored initially<br />

by Helen Keller International, that<br />

has exp<strong>and</strong>ed in the number of<br />

Barbara Underwood during her presentation at the CARIG Meeting, see<br />

page 18.<br />

communities covered <strong>and</strong> has<br />

demonstrated an improvement in<br />

vitamin A status (52). Agricultural<br />

approaches through plant breeding<br />

came onto the horizon in the<br />

latter part of the decade (56) but<br />

did not receive substantial support<br />

until the turn of the century.<br />

2000 forward: Where are we<br />

going?<br />

The end-of-decade goal for elimination<br />

of vitamin A deficiency was<br />

widely promoted in the 1990s but,<br />

although progress was made,<br />

the goal was not met. To keep<br />

up the momentum, new goals<br />

for elimination of micronutrient<br />

deficiencies were set for 2010 at<br />

the 2001 UN “World Fit for Children”<br />

meeting at UNICEF in New<br />

York. The question for program<br />

implementers is how to adapt<br />

existing strategies to assure that<br />

the extended time frame is met<br />

in a timely manner <strong>and</strong> not just<br />

reset at the end of the decade.<br />

Supplementation undoubtedly<br />

will continue for several years in<br />

certain country situations, but it<br />

will take resources <strong>and</strong> an intense<br />

effort to reach the vulnerable 30%<br />

who are now missed even in the<br />

best country distribution scenarios<br />

(18). Fortification efforts<br />

also will continue <strong>and</strong> undoubtedly<br />

will be increasingly effective<br />

in reaching rural communities<br />

<strong>and</strong> the poor as markets exp<strong>and</strong><br />

<strong>and</strong> economies develop. Public<br />

health measures through massive<br />

immunization campaigns,<br />

particularly for polio <strong>and</strong> measles,<br />

have made great inroads into<br />

control of immunizable infectious<br />

diseases, but these gains need to<br />

be complemented by improved<br />

environmental sanitation <strong>and</strong> safe<br />

water to control non-immunizable<br />

disease. Fortunately, more than<br />

at any point in my experience<br />

with vitamin A interventions, integrated<br />

approaches are gaining<br />

support, even food-based approaches.<br />

Indeed, the new kid on the foodbased<br />

micronutrient intervention<br />

playing field is biofortification.<br />

Although introduced in the mid-<br />

1990s (55) <strong>and</strong> the potential of<br />

the approach reviewed in 2000<br />

(56), substantial funding support<br />

only became available through<br />

the Bill <strong>and</strong> Melinda Gates Foundation<br />

in 20<strong>02</strong>. Biofortification is<br />

the cross-breeding of plants to<br />

increase the density of one or<br />

more nutrients, e.g. iron <strong>and</strong>/or<br />

zinc or provitamin β-carotene,<br />

<strong>and</strong>/or decrease inhibitors to<br />

absorption, e.g. phytates <strong>and</strong>/or<br />

polyphenols. At times, transgenic


SIGHT AND LIFE 16<br />

NEWSLETTER 2/2006<br />

methods may be used to introduce<br />

a nutrient otherwise absent,<br />

increase nutrient density above<br />

that achievable by cross-breeding,<br />

or insert favorable agronomic<br />

traits (e.g. disease resistance or<br />

increased yield). The advantage<br />

of biofortification is that staple<br />

crops grown <strong>and</strong> consumed by<br />

the poor can be enriched with micronutrients<br />

<strong>and</strong> be available harvest<br />

after harvest without added<br />

cost. β-carotene enriched crops<br />

currently being pursued include<br />

maize, cassava <strong>and</strong> sweet potato<br />

by traditional cross-breeding <strong>and</strong><br />

rice by transgenic technology.<br />

Golden Rice produced by Syngenta<br />

(SGR1) is the most publicized<br />

example using genetic<br />

manipulations to introduce genes<br />

to overcome the impediment to<br />

synthesis of β-carotene. Carotene<br />

enrichment of the original<br />

product was not impressive. It<br />

was about 1.6 µg/g rice, which<br />

carried limited potential for making<br />

significant contributions to<br />

vitamin A requirements in spite<br />

of heroic claims to the contrary.<br />

Announcement in 2005 of<br />

Golden Rice #2 (SGR2) changed<br />

the potential: SGR2 contains<br />

31 µg/g β-carotene (57). This is<br />

equivalent to 1033 µg RAE in<br />

400 g uncooked, milled rice (an<br />

adult male serving size of ~800<br />

g cooked rice daily) <strong>and</strong> 516 µg<br />

RAE in 200 g uncooked, milled<br />

rice (an estimated serving size of<br />

400 g cooked rice daily for a child<br />

> 3 years). These calculations assume<br />

12:1 conversion efficiency<br />

for β-carotene to vitamin A. However,<br />

feeding tests to estimate<br />

bioequivalence have not been<br />

reported to date. Nonetheless,<br />

factoring in an approximate 20%<br />

loss during cooking, 826 µg RAE<br />

would remain for an adult <strong>and</strong> 413<br />

µg RAE for a child. SGR2, therefore,<br />

could nearly meet the RDA<br />

across ages if the daily diet contained<br />

800 g <strong>and</strong> 400g of cooked<br />

rice eaten by adults <strong>and</strong> children,<br />

respectively. SGR2 is an example<br />

of using transgenic technology to<br />

introduce or improve carotenoids,<br />

particularly provitamin A, in staple<br />

crops grown <strong>and</strong>/or eaten by the<br />

poor, such as cassava <strong>and</strong> maize.<br />

There remains much research<br />

to be completed before such<br />

carotenoid enriched crops are<br />

available for public consumption.<br />

Bioavailability must be determined<br />

from the biofortified crops<br />

prepared for consumption by<br />

traditional cooking procedures.<br />

Equally important is gaining acceptance<br />

by consumers skeptical<br />

of transgenically produced<br />

food crops <strong>and</strong> of more intensely<br />

colored traditional crops.<br />

Biofortification, however, is not<br />

restricted to use of transgenic<br />

technology. There is potential<br />

through traditional crossbreeding<br />

of germ plasma from varieties<br />

with higher nutrient density <strong>and</strong><br />

other desired agronomic qualities.<br />

Perhaps the most advanced<br />

example in carotenoid-containing<br />

food plants is orange-fleshed<br />

sweet potato (OFSP) varieties.<br />

Although white sweet potato<br />

is the common staple eaten in<br />

many African countries, yelloworange<br />

varieties do exist in many<br />

countries. One particular orange<br />

variety (Resisto) has already been<br />

evaluated in a feeding trial among<br />

primary school children in South<br />

Africa <strong>and</strong> found to be acceptable<br />

<strong>and</strong> to improve vitamin A<br />

status (58).<br />

Some question whether vitamin A<br />

status can be maintained in a<br />

population using OFSP-based<br />

strategies. Jan Low recently completed<br />

a community intervention<br />

trial that found OFSP an acceptable<br />

substitute for white-fleshed<br />

sweet potato in Mozambique<br />

(59). An integrated agriculturedem<strong>and</strong><br />

creation-market development<br />

approach was implemented<br />

to introduce OFSP into<br />

intervention areas compared with<br />

a control community not provided<br />

OFSP vines. The 24-month study<br />

provided high-dose vitamin A<br />

capsules to all children at baseline<br />

<strong>and</strong> six months, a placebo<br />

in the intervention areas at 12<br />

months, <strong>and</strong> a high-dose capsule<br />

after specimen collection at 24<br />

months. Hence, for 12 months,<br />

no children in either the intervention<br />

or control areas received a<br />

vitamin A capsule. The difference<br />

was that only children in the intervention<br />

areas were exposed to<br />

OFSP <strong>and</strong> an intensive campaign<br />

to promote its consumption. At<br />

the end of the 12 month period,<br />

a significant difference was seen<br />

in the percentage of children with<br />

a serum retinol level less than<br />

0.7 µmol/l in the intervention<br />

groups, both before <strong>and</strong> after<br />

accounting for infection. Thus,<br />

vitamin A deficiency was reduced<br />

up to 24% among healthy children<br />

<strong>and</strong> 16% among those with<br />

evidence of infection. There were<br />

several other positive spin-offs<br />

from this integrated intervention,<br />

such as a substantial increase in<br />

knowledge of men <strong>and</strong> women,<br />

an increase in income for smallscale<br />

producers <strong>and</strong> an increase<br />

in daily caloric intake of the children,<br />

as well as the intake of other<br />

micronutrients in the OFSP.<br />

Biofortification of staple crops<br />

with micronutrients, including<br />

provitamin carotenoids, is still<br />

early in development. Yellow cassava,<br />

maize <strong>and</strong> banana/plantain<br />

are in the developmental stages.<br />

There is much research remaining<br />

to pair the best nutrient content<br />

with most desirable agronomic<br />

traits, bioavailability from products<br />

as consumed, consumer<br />

acceptance <strong>and</strong> economic advantages<br />

among other outst<strong>and</strong>ing<br />

issues. Nonetheless, a comparison<br />

of bio-fortification with<br />

fortification <strong>and</strong> supplementation<br />

clearly shows the complementary<br />

benefits of each intervention <strong>and</strong><br />

the potential in the long run of<br />

meeting the needs of the poor<br />

economically <strong>and</strong> safely through<br />

food, reserving high-dose supplementation<br />

for medical emergencies.

Conclusions<br />

Advances in underst<strong>and</strong>ing basic<br />

chemistry <strong>and</strong> functions of<br />

retinoids <strong>and</strong> carotenoids have<br />

been remarkable over the past<br />

four decades. This has paralleled<br />

progress in programs to control<br />

vitamin A deficiency through<br />

medical (supplement distribution)<br />

<strong>and</strong> market-based (food fortification)<br />

approaches. Progress has<br />

also occurred in public health<br />

programs to control immunilizable<br />

infectious diseases that drain<br />

body nutrient reserves, although<br />

there remain an estimated 1.1<br />

billion people without safe water.<br />

Whereas little attention was given<br />

to food-based approaches until<br />

recently, the future is promising<br />

due to breakthroughs that have<br />

occurred <strong>and</strong> are on the horizon<br />

for increasing carotenoids <strong>and</strong><br />

other micronutrient densities in<br />

staple crops eaten by the poor<br />

<strong>and</strong> in improving other agronomic<br />

characteristics that enhance<br />

yields through biofortification. For<br />

carotenoid chemists <strong>and</strong> program<br />

enthusiasts, the research opportunities<br />

are multiple to demonstrate,<br />

for example, bioavailability,<br />

cooking <strong>and</strong> preservation<br />

stability, acceptability, economic<br />

gains <strong>and</strong> biological effectiveness<br />

of these crops in contributing to<br />

control of micronutrient deficiencies,<br />

especially among the poor.<br />

Carotene Research Interaction Group (CARIG)<br />

Annual Conference 2006, San Francisco<br />

Noel W Solomons, Center for Studies of Sensory Impairment, Aging <strong>and</strong> Metabolism,<br />

Guatemala City, Guatemala<br />

The 2006 Carotene Research<br />

Interaction Group (CARIG) Annual<br />

Conference was convened<br />

on Saturday, 1 April at the Argent<br />

Hotel in San Francisco. It accompanied<br />

the Experimental Biology<br />

2006 meetings. This year’s<br />

conference was organized <strong>and</strong><br />

chaired by Dr. Elizabeth Johnson<br />

of Tufts University in Boston, a<br />

member of the CARIG Steering<br />

Committee. The proceedings<br />

began with the fifth annual James<br />

Allen Olson Perspective in Carotenoids<br />

lecture at CARIG, delivered<br />

by Dr. Barbara Underwood.<br />

She was a close associate of the<br />

late Prof. Olson, including jointly<br />

working in Brazil <strong>and</strong> serving as<br />

colleagues on the International<br />

Vitamin A Consultative Group<br />

(IVACG). She spoke on the topic:<br />

Reflections: Four Decades with<br />

Vitamin A <strong>and</strong> Carotenoids. (the<br />

full text of the James Allen Olson<br />

memorial lecture appears on<br />

page 10 of this issue). The significance<br />

of the talk was, in many<br />

ways, to show just how recent<br />

in emergence are the facts <strong>and</strong><br />

principles that we hold in common<br />

about assessing vitamin A<br />

status <strong>and</strong> on the necessity to<br />

develop public health intervention<br />

strategies against hypovitaminosis<br />

A. Dr. Underwood, as well as<br />

Prof. Olson, a founding member<br />

of CARIG <strong>and</strong> the force behind<br />

VARIG (the Vitamin A Research<br />

Interaction Group), were part of<br />

vitamin A discovery <strong>and</strong> consensus<br />

development. This was<br />

inspired by a crucial meeting held<br />

in Basel, Switzerl<strong>and</strong> in 1960, assessing<br />

the existing knowledge<br />

on vitamin A <strong>and</strong> pointing the way<br />

to the important next steps in the<br />

programmatic conquest of hypovitaminosis<br />

A. Dr. Underwood<br />

recounted three decades of contributions<br />

from IVACG, founded in<br />

1975, with about 35 experts in the<br />

vitamin A field in attendance. The<br />

lecture highlighted the steady <strong>and</strong><br />

solid accumulation of accurate<br />

biological <strong>and</strong> epidemiological<br />

knowledge about vitamin A deficiency.<br />

This would lead to the<br />

mobilization of a worldwide public<br />

health effort based primarily on<br />

high-dose supplement capsules<br />

or fortification of staple foods<br />

such as sugar or cooking oil.<br />

Of special interest for a carotenoid<br />

biology audience was<br />

Barbara Underwood’s particular<br />

point of view regarding public<br />

health interventions. She accused<br />

the sometimes rancorous<br />

discussions in the 1990s<br />

concerning the true efficiency<br />

of bioconverting provitamin A to<br />

yield active vitamin A of retarding<br />

the progress toward developing

SIGHT AND LIFE<br />

sustainable food-based alternatives<br />

to alleviate hypovitaminosis<br />

A. With that issue now resolved<br />

by a new consensus within the<br />

Dietary Reference Intakes of<br />

2001, she pointed to gathering<br />

momentum in the area of biofortification,<br />

citing the founding<br />

of the Harvest Plus Project. The<br />

emphasis of biofortification is on<br />

staple crops of abundant <strong>and</strong><br />

regular consumption by developing-country<br />

populations. Crossbreeding<br />

for hybrid varieties of<br />

sweet potato (orange-fleshed<br />

varieties) <strong>and</strong> genetic modification<br />

in the second (high-carotene)<br />

generation of Golden Rice were<br />

examples in which daily individual<br />

vitamin A needs could be met<br />

from the abundant supplies of<br />

β-carotene in these biofortified<br />

tubers <strong>and</strong> grains.<br />

A slide from Barbara Underwood<br />

advocating a holistic approach.<br />

An important <strong>and</strong> newsworthy<br />

note at the end of Dr. Underwood’s<br />

presentation was her announcement<br />

of the transformation of<br />

the IVACG. What began with its<br />

first meeting in 1975 ended with<br />

its 22nd meeting in Lima, Peru<br />

in 2004. A successor, the Micronutrient<br />

Forum, will be launched<br />

in Istanbul, Turkey, 16–18 April<br />

2007, with a broader <strong>and</strong> integrated<br />

m<strong>and</strong>ate involving vitamin<br />

A, iron, zinc, iodine <strong>and</strong> folic acid<br />

in a public health context.<br />

Those of us who care about<br />

human vitamin A nutriture can<br />

derive lessons <strong>and</strong> st<strong>and</strong>ards in<br />

the message of Dr. Underwood’s<br />

Reflections. Lessons relate to<br />

how to set an agenda for inquiry<br />

to rapidly advance basic <strong>and</strong> applied<br />

knowledge, <strong>and</strong> st<strong>and</strong>ards<br />

to gauge the expectations for<br />

progress in redressing vitamin A<br />

deficiency problems. Should the<br />

interests of vitamin A get “lost<br />

in the shuffle” of multiple micronutrients<br />

<strong>and</strong> diluted scientific<br />

expertise <strong>and</strong> attention in the<br />

Forum, these Reflections may<br />

become the cudgel to dem<strong>and</strong><br />

the attention for vitamin A issues<br />

that were clearly championed by<br />

Underwood <strong>and</strong> Olson during the<br />

past four decades.<br />

The second plenary lecture on the<br />

program was delivered by Dr. Earl<br />

Harrison, senior scientist at the<br />

USDA Human Nutrition Center at<br />

Beltsville, Maryl<strong>and</strong>. He spoke on<br />

the topic of Mechanisms Involved<br />

in the Intestinal Absorption of<br />

Dietary Carotenoids. This was a<br />

fitting <strong>and</strong> complementary companion<br />

theme to Dr. Underwood’s<br />

presentation with her emphasis<br />

on provitamin A carotenes from<br />

foods to supply vitamin A to deprived<br />

populations. To orient the<br />

audience, Dr. Harrison reviewed<br />

the conventional schematic aspects<br />

of dietary carotene uptake<br />

from the intestinal lumen into<br />

intestinal cells (enterocytes) <strong>and</strong><br />

the options for its further passage<br />

either as the intact carotenoid<br />

or as a derivative retinoid. Dr.<br />

Harrison <strong>and</strong> his co-worker have<br />

advanced evidence that both<br />

simple diffusion <strong>and</strong> a receptormediated<br />

transport (carotene<br />

transporters) are involved in the<br />

usual absorptive physiology of<br />

carotenoids.<br />

The laboratory at Beltsville has<br />

used a novel, in-vitro cell culture<br />

model, that of the Caco cell monolayer<br />

in a directional absorption<br />

chamber, to explore the mechanisms<br />

of absorption of dietary<br />

carotenoids. The absorption<br />

chamber experiments revealed<br />

an 11% fractional absorption for<br />

β-carotene, which is not so far<br />

Earl Harrison<br />

from the rate documented for the<br />

intact human intestine. Kinetic<br />

experiments showing saturation<br />

kinetics under certain conditions,<br />

however, are a strong argument<br />

that a “facilitated transport” is<br />

operating, <strong>and</strong> this is in line with<br />

a receptor involvement. A clever<br />

set of experiments in Caco cell<br />

cultures, stellate (Ito) cell (hepatic<br />

fat storage cells) cultures, <strong>and</strong><br />

cell-free microsomes (membrane<br />

envelopes) add credence to a<br />

transporter basis by showing<br />

stereo-specificity in uptake. In all<br />

three systems, different isomers<br />

of β-carotene were taken up to<br />

different extents. In descending<br />

order of uptake, affinity in the systems<br />

was revealed to be: all-trans<br />

β-carotene; 9-cis-β-carotene;<br />

<strong>and</strong> 13-cis-β-carotene.<br />

Bolstered by the coming together<br />

of cell-system evidence supporting<br />

a transported mechanism, Dr.<br />

Harrison’s research group has<br />

turned to identifying enzymes<br />

known to be located in the apical<br />

membrane of intact enterocytes,<br />

as c<strong>and</strong>idates for involvement in<br />

the transporter mechanism. Their<br />

search has centered on so-called<br />

class-B scavenger receptors,<br />

extensively studied for their involvement<br />

in cholesterol uptake.<br />

This has led pharmacologists<br />

to develop inhibitory agents for<br />

receptor uptake. This laboratory<br />

has also used mouse models<br />

with deletion of genes of specific


SIGHT AND LIFE 20<br />

NEWSLETTER 2/2006<br />

enzymes (the so-called “knock<br />

out” mouse) to draw inferences<br />

about pathways in carotene<br />

metabolism. Geneticist created<br />

knock-out animals, deprived of<br />

or suppressed regarding one or<br />

another receptor. These proved<br />

to be strong investigative tools<br />

to use in pursuing the role of<br />

transporters in carotene uptake.<br />

In concluding his talk, Dr Harrison<br />

summarized a series of Beltsville<br />

laboratory experiments using<br />

receptor inhibitors, knock-out<br />

mice <strong>and</strong> their combination, to<br />

illustrate a partial dependency of<br />

carotene uptake on this class of<br />

membrane-associated enzyme<br />

as the basis for facilitated cellular<br />

uptake of carotenoids in the<br />

intestine.<br />

Dr Kathleen C Ellwood, of the<br />

Center for Food Safety <strong>and</strong> Applied<br />

Nutrition (CFSAN) of the<br />

Food <strong>and</strong> Drug Administration<br />

(FDA) of the United States presented<br />

the topical theme Reviewing<br />

the Scientific Evidence for<br />

Health Claims. Dr. Ellwood is assigned<br />

to the Division of Nutrition<br />

Programs <strong>and</strong> Labeling, Office<br />

of Nutritional Products Labeling<br />

<strong>and</strong> Dietary Supplements of the<br />

CFSAN. She provided a lucid<br />

exposition of the United States<br />

government’s oversight <strong>and</strong> regulation<br />

in the food-labeling area,<br />

<strong>and</strong> participated in a lively <strong>and</strong><br />

interactive question <strong>and</strong> answer<br />

period thereafter. Need for labeling<br />

rules came about with the<br />

expansion of knowledge about<br />

bioactive substances in foods<br />

(of which the various carotenoids<br />

are examples). There came an<br />

effort by manufacturers of foods<br />

<strong>and</strong> supplements in the United<br />

States to transform findings into<br />

claims of beneficial effects. This<br />

led producers <strong>and</strong> marketers to<br />

seek to make claims about the<br />

benefits of consumption of the<br />

substances, the food containing<br />

the substances or both. To the<br />

extent that foods <strong>and</strong> substances<br />

are offered as remedies <strong>and</strong><br />

therapies, a specific regulatory<br />

Kathleen C Ellwood<br />

h<strong>and</strong>ling comes into play. Dr.<br />

Ellwood correctly presented this<br />

as a case example of the merger<br />

of science with policy.<br />

Claim statements for a product<br />

are a form of “speech”; within<br />

the United States of America,<br />

freedom of speech is protected<br />

by the First Amendment to the<br />

Constitution. Provisions for making<br />

claims for health regarding a<br />

retail product are now covered by<br />

legislation (statutes) <strong>and</strong> the judicial<br />

precedents (case law). The<br />

FDA considered disease therapy<br />

claims for foods in the 1970s <strong>and</strong><br />

1980s, <strong>and</strong> concluded that food<br />

must be treated by the same<br />

st<strong>and</strong>ards as any drug.<br />

Since that era, however, emerging<br />

scientific discovery has shown a<br />

series of more subtle diet-health<br />

relationships including protection<br />

<strong>and</strong> preservation of wellbeing<br />

<strong>and</strong> function. U.S. consumers<br />

were interested in seeking the<br />

potential benefits from dietary<br />

factors, <strong>and</strong> there was marketing<br />

pressure to deliver what the<br />

consumer dem<strong>and</strong>ed. This led to<br />

the passage in 1990 of the Nutrition<br />

Labeling <strong>and</strong> Educational<br />

Act, which governs the nature of<br />

claims that could be attached to<br />

edible products. It was not about<br />

treating established disease, i.e.<br />

the drug action, but rather about<br />

“Health Claims”. The act regulated<br />

claims of causal relationships<br />

between a food substance<br />

<strong>and</strong> a disease or health-related<br />

condition in the general US<br />

population or sub-population, in<br />

which consumption could reduce<br />

their risk. For the Health Claim to<br />

be approved the st<strong>and</strong>ard was<br />

“significant scientific agreement”,<br />

that is a strong consensus of a<br />

causal relationship.<br />

The speaker recounted how<br />

manufacturers felt constrained<br />

by having to get over such a high<br />

bar; they brought suits in court<br />

claiming that the Act infringed<br />

upon the First Amendment guarantee<br />

of freedom of speech. This<br />

has led, since 1999, to a secondary<br />

level of regulation for labeling,<br />

the so-called Qualified Health<br />

Claim (QHC). These claims include<br />

qualifying language in order<br />

to prevent the consumer from being<br />

misled. QHCs are applied for<br />

relationships such as that relating<br />

lycopene or lycopene-containing<br />

foods to reduced risk of prostate<br />

cancer <strong>and</strong> similar assertions.<br />

The process of evaluation by the<br />

FDA for a QHC has a defined<br />

set of steps. The first is literature<br />

review <strong>and</strong> selection. Animal<br />

studies are not relevant. Insofar<br />

as observational studies can<br />

indicate association, but not causality,<br />

the most relevant literature<br />

is considered to be that from intervention<br />

trials. The interventions<br />

can have outcomes of reduced<br />

incidence of disease/condition<br />

or favorable modification of a<br />

validated modifiable risk factor<br />

related to ill health.<br />

Prof. Erdman’s collaborators.<br />

Once the trial studies are assembled<br />

<strong>and</strong> sorted, those that meet<br />

inclusion criteria are rated for<br />

quality in terms of design, inclusion/exclusion<br />

criteria, balance<br />

of population characteristics<br />

across groups, verification of<br />

compliance with the intervention<br />

<strong>and</strong> appropriateness of statistical<br />

analysis. This is done for each<br />

study. The CARIG audience was<br />

particularly intrigued to learn that<br />

any study without a “validated”<br />

dietary intake method would be<br />

excluded from consideration. For<br />

those who know the limitations<br />

of dietary method validation/calibration,<br />

this seems fraught with<br />

arbitrary possibilities.<br />

The pre-final step is to rate the<br />

overall strength of the body of<br />

evidence in terms of type, quality,<br />

quantity <strong>and</strong> studies’ sample size,<br />

consistency <strong>and</strong> replication of<br />

findings, <strong>and</strong> the relevance to the<br />

US general population or target<br />

subgroups. Finally, the claim can<br />

have three degrees of ranking: 1.<br />

conclusive; 2. limited; or 3. very<br />

limited.<br />

The modifications in the FDA<br />

procedures derive from the tension<br />

among consumers’ desire to<br />

preserve health, producers’ <strong>and</strong><br />

retailers’ desire to exercise free<br />

speech, <strong>and</strong> the government’s<br />

duty to protect the citizenry from<br />

consumer fraud. Dr. Ellwood’s<br />

message had shown that the role<br />

of the scientific community lies in<br />

how well they design <strong>and</strong> execute<br />

studies on causal relationships<br />

between a dietary substance <strong>and</strong><br />

a beneficial outcome.<br />

Prof. John Erdman of the University<br />

of Illinois also spoke in the<br />

second session of the program<br />

with a talk entitled: Tomato, Lycopene<br />

<strong>and</strong> the Risk of Prostate<br />

Cancer. He was also awarded<br />

this year’s Wilbur O. Atwater<br />

Memorial Lecture, sponsored by<br />

the United States Department<br />

of Agriculture on 4 April, which<br />

had the theme of carotenes at its<br />

center. His award’s lecture topic<br />

was Colors, Critters, <strong>and</strong> Cancer.<br />

As he explained, the colors refer<br />

to carotenoid pigments; the critters<br />

refer to the selection (limits<br />

<strong>and</strong> possibilities) with different<br />

animal models for investigation<br />

of carotenoid metabolism <strong>and</strong><br />

effects; <strong>and</strong> cancer is specifically<br />

prostate cancer. The context is<br />

the epidemiological evidence that<br />

suggests that tomato consumption<br />

is protective against prostate<br />

cancer.<br />

The world of colorful carotenoids<br />

contains over 650 compounds.<br />

Phytoene <strong>and</strong> phytofluene are<br />

simple colorless precursor carotenoids.<br />

All known members of<br />

this family of compounds are initially<br />

synthesized in plant tissues;<br />

animals cannot form carotenoids.<br />

Prof. Erdman reminded his audiences<br />

that the ripeness of fruits<br />

John Erdman<br />

<strong>and</strong> vegetables is reflected in<br />

their carotenoid content. Carotenes<br />

contribute to the hues<br />

of birds’ feathers <strong>and</strong> insects’<br />

coloring. Moreover, carotenes are<br />

important to aroma compounds<br />

in nature that have importance for<br />

interspecies signaling.<br />

Not all animals h<strong>and</strong>le carotenoids<br />

in a uniform fashion.<br />

It has been found for instance<br />

that, for studies of carotenoid<br />

metabolism related to human<br />

physiology, gerbils, ferrets <strong>and</strong><br />

pre-ruminant calves provide the<br />

best in likeness to human absorptive<br />

systems. They are capable<br />

of absorbing the compounds<br />

both intact <strong>and</strong> metabolized. As<br />

herbivores, rats <strong>and</strong> mice are efficient<br />

converters of provitamin A<br />

carotenoids. They are poor at<br />

absorbing intact carotenoids;<br />

thus, high feed levels are needed<br />

for these rodents to replicate the<br />

tissue concentrations achieved in<br />

humans. In Prof. Erdman’s view,<br />

the armamentarium of animal<br />

models for cancer studies with<br />

carotenoids includes rats, mice,<br />

<strong>and</strong> again ferrets.<br />

The prostate gl<strong>and</strong> <strong>and</strong> carotenoid-containing<br />

foods came<br />

together in the observations of<br />

vastly different spontaneous incidence<br />

rates for prostatic cancer<br />

with 70 times greater incidence<br />

rates in North American blacks<br />

<strong>and</strong> 50-fold increased rates

Maria Stacewicz-Sapuntzakis receives award from Wendy White.<br />

in North American whites, as<br />

compared to peers in Shanghai,<br />

China. The Physicians’ Health<br />

Study implicated higher intakes<br />

of tomato sauce, tomatoes, pizza<br />

<strong>and</strong> strawberries, all sources of<br />

lycopene (a non-provitamin A<br />

carotenoid), with reduced prostate<br />

cancer occurrence. Prof.<br />

Erdman summarized the science<br />

findings of his group in pursuing<br />

the bases of these epidemiological<br />

observations. Using a prostatic<br />

cancer murine tumor model,<br />

the combination of broccoli <strong>and</strong><br />

tomato proved to be superior<br />

to tomato alone, <strong>and</strong> both were<br />

superior to isolated lycopene in<br />

terms of anti-cancer activity in the<br />

mouse tumors. The conclusion<br />

is that lycopene is not the only<br />

preventive substance in broccoli<br />

or tomatoes.<br />

At the VARIG/CARIG social event.<br />

The other basic pursuit involved<br />

the potential bioactivity of metabolic<br />

derivatives of lycopene.<br />

Analogous to the format by which<br />

retinoids <strong>and</strong> apo-carotenals<br />

of different carbon lengths are<br />

produced by central or eccentric<br />

cleavage of provitamin A carotenes,<br />

the search has been joined<br />

for generation of apo-lycopenals.<br />

The carotene monoxygenase I<br />

(CMO I), responsible for central<br />

cleavage of β-carotene (formerly<br />

known as 15,15’ monoxygenase)<br />

is inactive in cleaving lycopene.<br />

However, the carotene monoxygenase<br />

II (CMO II), which produces<br />

eccentric cleavage of β-carotene,<br />

can also generate apo-lycopenals<br />

in in-vitro systems. These products<br />

have recently been detected<br />

with sensitive assay techniques<br />

in human plasma <strong>and</strong> breast milk<br />

in concentrations over 100 times<br />

lower than that of lycopene itself.<br />

Studies documenting the bioactivity<br />

of lycopene split-products have<br />

yet to appear, but the fundamentals<br />

of carotene biology for retinoids<br />

are a template for inquiry into<br />

potential anti-cancer mechanisms<br />

for lycopene.<br />

The final wisdom from Prof.<br />

Erdman is not to ignore other<br />

compounds, even phytoene <strong>and</strong><br />

phytofluene precursors. In the<br />

ripe tomato, the sum of these<br />

two compounds is equivalent by<br />

weight to that of lycopene, <strong>and</strong><br />

these non-aromatic forms are 10<br />

times more abundant than alpha<strong>and</strong><br />

beta-carotenes combined.<br />

13 th European Meeting on Fat-Soluble Vitamins<br />

2006 in Jena<br />

Volker Böhm, PD, Institut für Ernährungswissenschaften, Friedrich-Schiller-Universität<br />

Jena, Germany<br />

This year, for the first time, this<br />

European Conference took place<br />

in Germany. Fat-soluble vitamins<br />

(FSV) offer a wide field of research<br />

<strong>and</strong> have brought together European<br />

scientists <strong>and</strong> students every<br />

three to four years since 1960,<br />

first in the UK <strong>and</strong> then touring<br />

Europe. After Arcachon (1996)<br />

<strong>and</strong> Toulouse (2000) in France<br />

<strong>and</strong> Rieti (2003) in Italy, this year<br />

Jena in Germany provided an opportunity<br />

to listen <strong>and</strong> to lecture,<br />

to discuss <strong>and</strong> to develop stateof-the-art<br />

<strong>and</strong> new approaches,<br />

illuminating the role of these<br />

compounds for human health <strong>and</strong><br />

more. A very efficient interchange<br />

of knowledge took place due to<br />

the traditionally small number of<br />

around 50 participants. Students,<br />

in particular, took this opportunity<br />

to present their work on a European<br />

level <strong>and</strong> to talk to experts<br />

in the field.<br />

The 13 th FSV meeting was hosted<br />

by the Institute of Nutrition at<br />

the renowned Friedrich Schiller<br />

University in Jena. It took place<br />

in the Old Castle in Dornburg<br />

(10 km from Jena), that has just<br />

been completely refurbished to<br />

meet the dem<strong>and</strong>s of a modern<br />

meeting place while keeping its<br />

beautiful historical ambience.<br />

Accommodation was in Jena, a<br />

city of 100,000 inhabitants <strong>and</strong><br />

also famous for its optical trade<br />

(Zeiss, Jenoptik).<br />

The conference started with a<br />

plenary lecture by the internationally<br />

known carotenoid expert<br />

Steven J Schwartz from the Ohio<br />

State University in Columbus,<br />

Ohio, USA. He presented some<br />

of the results of his group on bioavailability<br />

of different carotenoids,<br />

talking also on bioactivity of<br />

these secondary plant products<br />

being able to reduce the risks<br />

for some degenerative diseases.<br />

The first session followed, reporting<br />

results with carotenoids.<br />

Catherine Caris-Veyrat from INRA<br />

Avignon, France, mainly focused<br />

on oxidation products of carotenoids,<br />

discussing some possible<br />

effects of these metabolites. Yoav<br />

Sharoni from Beer-Sheva, Israel,<br />

presented new results on mechanisms<br />

for cancer prevention by<br />

carotenoids, while Gordon Lowe<br />

from Liverpool, UK, explained<br />

investigations on interactions<br />

between cigarette smoke <strong>and</strong><br />

β-carotene.<br />

The second session focussed on<br />

vitamin E. David Muller, London,<br />

UK, presented analytical details<br />

on separation <strong>and</strong> quantification<br />

of conjugated vitamin E metabolites<br />

in sepsis. Andreas Wagner<br />

from Jena, Germany, showed<br />

how intervention with α-tocopherol<br />

<strong>and</strong> folic acid affected 8-<br />

oxodG, a biomarker of oxidative<br />

stress in leukocytes <strong>and</strong> urine<br />

in humans. Stefano Manfredini,<br />

Ferrara, Italy, finished the session,<br />

comparing the antioxidant<br />

activity of novel vitamin E based<br />

antioxidants within several assay<br />

systems. Afterwards most delegates<br />

enjoyed typical Thuringian<br />

sausages, beer <strong>and</strong> jazz music.<br />

The second day started with<br />

results on the structure-activity<br />

relationship of carotenoid derivatives<br />

in activation of the antioxidant<br />

response element transcription<br />

system, presented by Joseph<br />

Levy, Beer-Sheva, Israel. Paola

Palozza, Rome, Italy, discussed<br />

experiments with β-carotene<br />

in vascular cells exposed to<br />

oxysterols. Investigations on<br />

carotenoid metabolism in animals<br />

were presented by Johannes<br />

von Lintig, Freiburg, Germany.<br />

A round-table discussion on<br />

perspectives for fat-soluble vitamins<br />

led to an intense exchange<br />

between the experts, showing a<br />

lot of interesting tasks to be investigated<br />

in the next years. The<br />

discussion closed with the decision<br />

to continue the meetings in<br />

the future. Two colleagues offered<br />

to invite the scientists in 2009 to<br />

Potsdam, Germany, <strong>and</strong> in 2012<br />

to Greece.<br />

After lunch, Diana Bellovino,<br />

Rome, Italy, presented investigations<br />

on the effect of the matrix<br />

on the bioavailability of carotenoids.<br />

Anna Iannone, Modena,<br />

Italy, discussed new results from<br />

electron spin resonance experiments<br />

investigating the antioxidant<br />

potential of α-tocopherol<br />

<strong>and</strong> lycopene. After an official<br />

reception by the Mayor of Jena all<br />

delegates used the time to have<br />

a look at the posters. Some delegates<br />

spent the afternoon break<br />

walking through the gardens of<br />

the castle grounds; others enjoyed<br />

discussing <strong>and</strong> relaxing<br />

in small groups. A dinner <strong>and</strong><br />

music event was the highlight of<br />

the second evening. European<br />

food prepared by local cooks<br />

was combined with local wines<br />

of the most Northern vineyard in<br />

Germany <strong>and</strong> European music<br />

played by m<strong>and</strong>olins <strong>and</strong> guitars<br />

of the group “Lautengilde Jena”,<br />

conducted by the organizer of<br />

the meeting – the large hall of the<br />

castle provided a good ambience<br />

for the event.<br />

The last half-day of the conference<br />

started with an update on<br />

isomerization of lycopene presented<br />

by Volker Böhm, Jena,<br />

Germany. Emmanuelle Reboul,<br />

Marseille, France, explained<br />

which transporters are involved<br />

in the uptake of lycopene <strong>and</strong><br />

β-carotene. Wilhelm Stahl, Düsseldorf,<br />

Germany, finished the<br />

carotenoid session with experiments<br />

showing photoprotective<br />

effects of carotenoids. In the last<br />

session of the meeting Hülya<br />

Sagmanligil Özdemir, Van, Turkey,<br />

presented results on fat-soluble<br />

antioxidant vitamin levels in<br />

newborn babies <strong>and</strong> their relation<br />

to the maternal vitamin status.<br />

Patrick Borel, Marseille, France,<br />

talked about different lipases being<br />

responsible for hydrolysis of<br />

retinyl palmitate.<br />

Three awards for the best posters,<br />

elected by all delegates,<br />

some concluding remarks <strong>and</strong> a<br />

farewell finished two very efficient<br />

days within the old walls of Dornburg<br />

Castle. All delegates left the<br />

conference venue more relaxed<br />

than when they arrived, which<br />

could well be an additional effect<br />

of the charming atmosphere <strong>and</strong><br />

the small number of delegates. All<br />

were invited to come to the 14 th<br />

European Meeting on Fat-Soluble<br />

Vitamins that will take place in<br />

2009 in Potsdam, Germany, organized<br />

SIGHT AND LIFE<br />

Protecting nutritional status <strong>and</strong> the role of micronutrient<br />

premix in the United Nations World Food<br />

Programme’s response to the Indian Ocean Tsunami<br />

World Food Programme, Regional Bureau for Asia, Wave Place Building, 7th Floor, 55<br />

Wireless Road, Pathumwan, Bangkok 10330, Thail<strong>and</strong><br />

Immediate relief<br />

The Indian Ocean Tsunami of 26<br />

December 2004 presented the<br />

humanitarian community with<br />

one of the largest challenges it<br />

had ever faced. The United Nations<br />

World Food Programme responded<br />

with an immediate <strong>and</strong><br />

massive relief effort that eventually<br />

became one of the most complex<br />

operations the organization<br />

had ever undertaken, spanning<br />

six countries, two continents, <strong>and</strong><br />

millions of beneficiaries.<br />

While the primary focus of the immediate<br />

response was providing<br />

life-sustaining food aid to those<br />

whose houses, fields, crops <strong>and</strong><br />

livelihoods had been washed<br />

away, WFP also sought to shore<br />

up the nutritional status of groups<br />

made vulnerable by the tsunami<br />

– in particular children, new mothers<br />

<strong>and</strong> the elderly.<br />

In such situations, ready-to-eat<br />

or easy-to-prepare fortified foods<br />

play a key role. Within days of<br />

the tsunami, WFP found itself<br />

required to deliver large quantities<br />

of such foods to the crisis zone<br />

in record time. In Aceh <strong>and</strong> Nias,<br />

WFP had not been providing fortified<br />

foods prior to the tsunami,<br />

so it turned to countries in the region,<br />

such as Bangladesh, where<br />

WFP was producing such foods<br />

in large quantities .<br />

DSM, which is one of WFP’s<br />

primary private-sector partners<br />

in nutrition, responded quickly<br />

through SIGHT AND LIFE to<br />

WFP’s requests for assistance<br />

by donating micronutrient premix<br />

– enough to fortify over 5,000<br />

metric tons of high-energy biscuits.<br />

Such biscuits are used<br />

primarily in WFP’s school feeding<br />

programs, as a mid-morning<br />

snack designed to help prevent<br />

micronutrient deficiencies among<br />

school children. They are also<br />

extremely useful in emergencies,<br />

as they are lightweight <strong>and</strong> easy<br />

to transport, yet provide high nutritional<br />

<strong>and</strong> caloric value.<br />

SIGHT AND LIFE’s donation was<br />

delivered to factories in Bangladesh<br />

that produce fortified<br />

biscuits for WFP. The donation<br />

allowed WFP to release large<br />

quantities of fortified biscuits in<br />

Bangladesh <strong>and</strong> send them to<br />

countries across the crisis zone.<br />

Planes filled with biscuits started<br />

leaving Dhaka on 13 January.<br />

By the end of January, 700 metric<br />

tons of biscuits had been shipped<br />

to Aceh, Indonesia, by both air<br />

<strong>and</strong> sea. This was a major donation,<br />

representing 15% of the<br />

total amount of biscuits used in<br />

the entire tsunami operation in<br />

2005. The biscuits sent to Indonesia<br />

were enough to provide<br />

nutritional supplementation to<br />

over 300,000 children aged 3 to<br />

12 years for three months.<br />

Sri Lanka, the Maldives, Thail<strong>and</strong>,<br />

Myanmar <strong>and</strong> Somalia. As the<br />

acute crisis passed, the focus of<br />

operations shifted from averting<br />

wide-scale hunger to protecting<br />

groups left vulnerable by the<br />

disaster. These groups included<br />

displaced people, farmers whose<br />

l<strong>and</strong> had been inundated, <strong>and</strong><br />

fishing families who had lost their<br />

boats or other means of fishing.<br />

In many cases, these communities<br />

had had relatively stable food<br />

security prior to the tsunami. In<br />

other cases, the waves had made<br />

difficult conditions much worse.<br />

Across the board, however, the<br />

emphasis was not so much on<br />

raising pre-existing nutritional<br />

levels as making sure that nutritional<br />

levels did not decline as<br />

a result of the tsunami <strong>and</strong> its<br />

after-effects.<br />

As a recent joint statement by<br />

WFP, UNICEF <strong>and</strong> the WHO<br />

on “Preventing <strong>and</strong> Controlling<br />

Micronutrient Deficiencies<br />

in Populations Affected by an<br />

Emergency” puts it: “The aim is<br />

to avert micronutrient deficiencies<br />

or prevent them from getting<br />

worse among the affected<br />

population. Such foods must be<br />

appropriately fortified, taking into<br />

account the fact that other unfortified<br />

foods will meet a share of<br />

micronutrient needs.”<br />

Adults who were displaced or<br />

part of otherwise vulnerable<br />

groups received daily rations for<br />

their entire families (generally rice,<br />

canned fish, fortified noodles<br />

<strong>and</strong> oil in Indonesia; rice, pulses,<br />

sugar <strong>and</strong> oil in Sri Lanka). Children<br />

in school received either the<br />

fortified biscuits (Indonesia <strong>and</strong><br />

Maldives) or a mid-day meal (Sri<br />

Lanka). New mothers <strong>and</strong> young<br />

children received fortified food<br />

<strong>and</strong> nutrition education through<br />

Mother <strong>and</strong> Child Nutrition (MCN)<br />

programs.<br />

Boys at school in B<strong>and</strong>a Aceh. WFP/ Barry Came.<br />

By December 2005, school feeding<br />

programs covered 330,000<br />

children in Indonesia <strong>and</strong> 1<strong>02</strong>,000<br />

in Sri Lanka. Over 143,000 mothers<br />

<strong>and</strong> young children were<br />

enrolled in MCN programmes in<br />

Sri Lanka, along with 33,000 in<br />

Indonesia, with plans to exp<strong>and</strong><br />

the programs in both countries.<br />

At the same time, the number of<br />

beneficiaries receiving general<br />

food rations was decreasing, as<br />

homes were built <strong>and</strong> people returned<br />

to their old livelihoods.<br />

Fortified foods such as highenergy<br />

biscuits played a critical<br />

role in the early days of the response,<br />

<strong>and</strong> in the future-oriented<br />

programs such as school feeding<br />

which aimed to shore up the nutritional<br />

status of communities.<br />

However, fortified biscuits were<br />

not used as emergency rations<br />

in the early stages to the degree<br />

originally planned. The relatively<br />

rapid re-opening of l<strong>and</strong> routes<br />

– in Aceh in particular – meant<br />

that communities could receive<br />

st<strong>and</strong>ard rations by truck transport,<br />

rather than having to rely<br />

on flown-in fortified foods. In the<br />

end, WFP used approximately<br />

half of the amount of fortified biscuits<br />

that it had originally planned<br />

for the entire tsunami operation.<br />

Following the initial shipments<br />

of 700 metric tons of fortified<br />

biscuits to Indonesia, as well as<br />

other shipments to the Maldives<br />

<strong>and</strong> Sri Lanka, WFP was able to<br />

source the remaining biscuits that<br />

it needed locally. As a result, the<br />

remainder of the SIGHT AND LIFE<br />

donation was used to produce<br />

biscuits in Bangladesh for use in<br />

WFP school feeding programs in<br />

that country.<br />

The rapid response of SIGHT<br />

AND LIFE <strong>and</strong> other WFP partners<br />

to the tsunami was critical,<br />

allowing WFP to provide large<br />

quantities of fortified foods to the<br />

affected areas. Without it, certain<br />

communities might have faced<br />

a drop in children’s nutritional<br />

levels, along with all the other<br />

challenges brought in the wake<br />

of the waves.<br />

Additionally, the donation provided<br />

much-needed support for<br />

school feeding in Bangladesh.<br />

WFP plans to provide fortified<br />

meals or supplementary snacks<br />

to 300,000 children in Bangladesh<br />

in 2006. While these programs<br />

may not be as dramatic<br />

as the tsunami response, in terms<br />

of the impact on children’s lives<br />

they can be more widespread<br />

<strong>and</strong> longer-lasting. Long after the<br />

reconstruction of the tsunami-hit<br />

areas is over, the world will still<br />

face the ongoing “silent emergencies”<br />

of malnourished children,<br />

<strong>and</strong> children who are denied an<br />

education due to poverty.

Distributing micronutrients <strong>and</strong> deworming<br />

medicine in hurricane-ravaged Honduras<br />

Howard B Schiffer, Executive Director, Vitamin Angels Alliance,<br />

Santa Barbara, CA, USA<br />

Background<br />

Hurricane Mitch struck northwestern<br />

Honduras with devastating<br />

effects in 1998, setting back<br />

the remarkable progress that the<br />

country had been making in addressing<br />

their problems of health<br />

care, education <strong>and</strong> poverty.<br />

Honduras now faces daunting<br />

issues as it attempts to address<br />

serious health conditions such as<br />

malnutrition, child mortality, dengue<br />

fever, respiratory infections,<br />

HIV/AIDS <strong>and</strong> rapid population<br />

growth. Malnutrition, coupled<br />

with infestations of parasites, is<br />

a serious problem for children.<br />

Unfortunately, micronutrient deficiencies<br />

are found at high levels<br />

in the north <strong>and</strong> west rural regions<br />

of Honduras <strong>and</strong> were made<br />

worse by the hurricane <strong>and</strong> its<br />

aftermath.<br />

While it is widely understood<br />

that vitamin A <strong>and</strong> other micronutrient<br />

deficiencies are a major<br />

cause of disease <strong>and</strong> blindness<br />

among children, parasites are<br />

also a leading cause of diseases<br />

among children <strong>and</strong> adults in the<br />

world today. Worms consume<br />

macro- <strong>and</strong> micronutrients in the<br />

gut before children can absorb<br />

them, <strong>and</strong> hence impair children’s<br />

growth <strong>and</strong> developement. This<br />

can lead to physical stunting,<br />

learning problems, illness <strong>and</strong><br />

death. Deworming these children<br />

is essential for their health <strong>and</strong><br />

well-being <strong>and</strong> is an essential<br />

component of a micronutrient<br />

campaign.<br />

As was reported in SIGHT AND<br />

LIFE <strong>Newsletter</strong> 2/2005 (pp. 20–<br />

21), Vitamin Angel Alliance (VAA)<br />

<strong>and</strong> Cristo Salva are running a<br />

project to provide basic medical<br />

services <strong>and</strong> combat malnutrition<br />

in Honduras. Now, with the support<br />

of SIGHT AND LIFE, these<br />

efforts are continuing in the form<br />

of the Honduras Micronutrient<br />

Project. This campaign, which<br />

is commencing this year, will alleviate<br />

micronutrient deficiency<br />

<strong>and</strong> VAD (vitamin A deficiency),<br />

<strong>and</strong> reduce the parasitic worm<br />

load for 30,000 children from two<br />

to ten years old in northwestern<br />

Honduras. We are working with<br />

local school districts to distribute<br />

chewable multivitamin <strong>and</strong><br />

micronutrient supplements <strong>and</strong><br />

educate parents to have their<br />

children take one daily, <strong>and</strong> we<br />

are distributing mebendazole<br />

(500 mg) once every 6 months to<br />

eliminate parasitic worms.<br />

The project sites<br />

The project sites are rural villages<br />

in northwestern Honduras near<br />

the Guatemalan border. These<br />

are the little villages around the<br />

central village of Macuelizo.<br />

Hacienda Cristo Salva is located<br />

in one of the small neighboring<br />

villages – Las Varas – <strong>and</strong> the<br />

Clinica de Cristo Salva is located<br />

in the center of Macuelizo with<br />

central access to all the villages.<br />

Specifically, Cristo Salva distributes<br />

the micronutrients <strong>and</strong><br />

mebendazole in the towns <strong>and</strong><br />

villages in <strong>and</strong> surrounding the<br />

Valley of Macuelizo.<br />

The villages have no medical care<br />

whatsoever. The poverty in the<br />

region is endemic <strong>and</strong> extreme.<br />

Many of these children literally<br />

eat a root on their way to school<br />

in the morning for their breakfast.<br />

Professor Oscar Mendoza, the<br />

former District Officer <strong>and</strong> current<br />

head teacher in a local middle<br />

school, agreed to work with<br />

Cristo Salva to help mitigate in<br />

part the sickness <strong>and</strong> hunger of<br />

the children. In addition, Cristo<br />

Salva has a network of people on<br />

the school boards, village officials<br />

<strong>and</strong> even translators who have<br />

offered to assist us.<br />

The campaign<br />

Cristo Salva distributes the products<br />

to the schools, with school<br />

officials helping to oversee the<br />

process. Cristo Salva plans a<br />

teachers’ meeting in each community<br />

to educate teachers <strong>and</strong><br />

ute the parasitic medicines (along<br />

with an education program on<br />

basic hygiene <strong>and</strong> sanitation) <strong>and</strong><br />

how to educate the parents about<br />

the daily supplements for their<br />

children. The periodic, organized<br />

distribution of mebendazole<br />

supplements has worked successfully<br />

in our past experience<br />

<strong>and</strong> we are confident about the<br />

progress of this project. During<br />

the first year it is planned to<br />

reach 30,000 children <strong>and</strong> in the<br />

second <strong>and</strong> third year others not<br />

yet reached will be included.<br />

A grant to run the project <strong>and</strong> the<br />

micronutrients are being donated<br />

by SIGHT AND LIFE. The tableting<br />

is being contributed by Anabolic<br />

Labs with excipient contributions<br />

from Domino Foods <strong>and</strong> Mutual<br />

Foods. The mebendazole is being<br />

purchased from (<strong>and</strong> partially donated<br />

by) MedPharm. PAHO (Pan<br />

American Health Organization) is<br />

supplying the Kato Katz test kits<br />

for the baseline study. Support<br />

on the baseline study is being<br />

provided by George Washington<br />

University <strong>and</strong> the Ministry of<br />

Health (MOH) in Honduras.<br />

The distribution of the products<br />

follows strict guidelines. The<br />

in-country partners of the mebendazole<br />

part of the campaign<br />

receive WHO survey materials<br />

<strong>and</strong> guidelines for administering<br />

safe <strong>and</strong> appropriate doses of<br />

mebendazole to children. Only<br />

trained healthcare workers or<br />

volunteers administer the doses<br />

<strong>and</strong> maintain accurate record<br />

sheets about children receiving<br />

supplements <strong>and</strong> mebendazole.<br />

They ascertain the child’s age<br />

– through discussion with caregiver,<br />

or by observing the ambulatory<br />

ability of the child. The<br />

caregivers are instructed to give<br />

the children one micronutrient<br />

vitamin/mineral chewable tablet<br />

each day. Based on the records of<br />

individual children an evaluation<br />

<strong>and</strong> follow up of the campaign is<br />

possible.<br />

Partners<br />

Vitamin Angel Alliance is the<br />

lead agency for the program.<br />

Our mission is to provide basic<br />

nutrition to people in need. Our<br />

vision is far reaching. We believe<br />

that every person has a right to<br />

basic nutrition; that malnutrition<br />

linked diseases are preventable<br />

<strong>and</strong> that education in addition to<br />

supplementation is essential for<br />

long-term health. A more detailed<br />

scope of the mission of VAA was<br />

given in SIGHT AND LIFE <strong>Newsletter</strong><br />

2/2005 (pp. 20–21).<br />

Cristo Salva is implementing<br />

the program in Honduras. It is<br />

a non-profit NGO consisting<br />

of lay people, doctors, nurses,<br />

teachers, <strong>and</strong> missionaries. For<br />

15 years it has been serving the<br />

people of Honduras, focused<br />

primarily in the State of Santa<br />

Barbara. The vision of Cristo<br />

Salva is to provide basic needs in<br />

the form of vitamins, clean water,<br />

hygienic education, agricultural<br />

education, nutritional education<br />

<strong>and</strong> support, medical <strong>and</strong> dental<br />

clinics, pre-natal education, eye<br />

glasses, clothing, <strong>and</strong> shoes.<br />

Goals, outcomes <strong>and</strong><br />

reports<br />

The records kept, using WHO<br />

survey materials, will give information<br />

on:<br />

• Number of community meetings<br />

held<br />

• Number of micronutrient supplements<br />

distributed<br />

• Number of worm tablets distributed<br />

• Number <strong>and</strong> ages of children<br />

reached<br />

It is expected that the benefits<br />

gained will be reduced blindness,<br />

morbidity, mortality <strong>and</strong> clinic<br />

visits as well as improved general<br />

health. Some of the benefits may<br />

be difficult to quantify. However,<br />

there is no doubt that these reductions<br />

in health problems<br />

will enable health workers <strong>and</strong><br />

facilities to redirect a substantial<br />

portion of their resources to other<br />

public health <strong>and</strong> socio-economic<br />

concerns.<br />

The Honduran Micronutrient<br />

Campaign will be monitored <strong>and</strong><br />

evaluated by VAA with full participation<br />

by Cristo Salva <strong>and</strong> other<br />

in-country partner organizations.<br />

The primary emphasis will be on<br />

the coverage of the program, with<br />

results largely based on the supplements<br />

<strong>and</strong> medication reaching<br />

the intended beneficiaries.

Eye care mission to the Dominican Republic,<br />

March 2006<br />

Sade Kosoko-Lasaki, MD, MSPH, MBA, Creighton University, Omaha, NE, USA<br />

Introduction<br />

During our previous trip to the<br />

Dominican Republic (DR), we<br />

demonstrated that VAD is a public<br />

health problem in this country.<br />

This was reported in SIGHT AND<br />

LIFE <strong>Newsletter</strong> 2/2005 (pp.<br />

35–36) with more details given in<br />

the 3/2005 issue (pp. 21–23).<br />

In March 2006, Creighton University<br />

realized a similar mission with<br />

the same partners. In addition to<br />

the screening of children <strong>and</strong> the<br />

administration of vitamin A capsules,<br />

adults were examined for<br />

glaucoma. Glaucoma is also the<br />

commonest cause of blindness<br />

in African-American <strong>and</strong> Hispanic<br />

populations.<br />

The primary health care workers<br />

(Cooperadores) received a halfday<br />

review <strong>and</strong> training session<br />

on the clinical signs <strong>and</strong> symptoms<br />

of vitamin A deficiency, its<br />

effects on childhood morbidity<br />

<strong>and</strong> mortality <strong>and</strong> preventative<br />

strategies. Dr. Kosoko-Lasaki<br />

emphasized the benefits of<br />

breast-feeding <strong>and</strong> encouraged<br />

the consumption of foods rich<br />

in vitamin A, such as green leafy<br />

vegetables, carrots, mangoes,<br />

papaya, etc. The Cooperadores<br />

also received lectures on the<br />

importance of adults having their<br />

eyes screened for glaucoma. All<br />

the Cooperadores received eye<br />

exams <strong>and</strong> screening. Two new<br />

cases of glaucoma were identified<br />

amongst the group.<br />

Other trip activities included<br />

screening children for the eye<br />

signs of vitamin A deficiency,<br />

distributing vitamin A capsules,<br />

<strong>and</strong> providing screening <strong>and</strong><br />

ocular examination <strong>and</strong> treatment<br />

for adults, specifically for<br />

glaucoma. In addition, a lecture<br />

to the Ophthalmology Society on<br />

the importance of screening for<br />

glaucoma was delivered by Dr.<br />

Kosoko-Lasaki.<br />

Results<br />

Approximately 200 children,<br />

ages 3 months to 10 years, were<br />

screened <strong>and</strong> received vitamin A.<br />

A total of 178 adults received visual<br />

acuity, visual field (using the FDT<br />

Visual Field Analyzer), slit lamp,<br />

tonometry <strong>and</strong> fundus exams.<br />

Ninety-four patients had complete<br />

ophthalmologic exams. Thirty new<br />

cases <strong>and</strong> 44 existing cases of<br />

glaucoma were diagnosed, <strong>and</strong><br />

six glaucoma surgeries were performed.<br />

Follow-up referrals were<br />

sent to Dr. Sebastian Guzman <strong>and</strong><br />

to the ILAC clinic in Santiago.

Conclusion<br />

The children, adults, <strong>and</strong> health<br />

care personnel in the DR benefited<br />

from the efforts of the Eye<br />

Care team <strong>and</strong> its collaborative<br />

approach with the local Santiago<br />

ophthalmologist <strong>and</strong> ILAC family<br />

practice physicians. The ILAC<br />

Cooperadores (health care workers)<br />

use the “teach-the-teacher”<br />

strategy. This grass-roots ap-<br />

proach reaches the poor <strong>and</strong><br />

marginalized residents in the<br />

remote, underserved areas of the<br />

Dominican Republic.<br />

Update on the status of vitamin A deficiency<br />

<strong>and</strong> xerophthalmia in children under five treated<br />

at hospitals in Vietnam over a 27-year period<br />

(1979 – 2005)<br />

Nguyen Chi Dzung MD, PhD, Hanoi National Institute of Ophthalmology,<br />

Tran Minh Tan MD, Hanoi National Children’s Hospital, Vietnam<br />

In 2005 cases with eye signs of<br />

vitamin A deficiency (125 cases<br />

with XN) were still seen in many<br />

hospitals in Vietnam, especially in<br />

remote <strong>and</strong> mountainous areas.<br />

Similar findings were published<br />

in previous issues (see SIGHT<br />

AND LIFE <strong>Newsletter</strong> 1/20<strong>02</strong> pp.<br />

12–14). Due to the sporadic cases<br />

of VAD still found, not only in<br />

the community but also in some<br />

hospitals, <strong>and</strong> the persistent risk<br />

of blindness for children in some<br />

remote <strong>and</strong> mountainous areas,<br />

the VAD prevention <strong>and</strong> control<br />

program needs to be continued,<br />

with the focus on mountainous,<br />

remote <strong>and</strong> economically impoverished<br />

areas in order to totally<br />

eliminate xerophthalmia by the<br />

year 2010.<br />

Therefore we hope to continue<br />

to receive support from SIGHT<br />

AND LIFE in the form of vitamin A<br />

capsules in order to achieve this<br />

goal of eliminating xerophthalmia<br />

<strong>and</strong> VAD in Vietnam.<br />

We always highly appreciate international<br />

assistance, which is<br />

very valuable. On this occasion,<br />

we would like to express the<br />

sincere thanks of our people <strong>and</strong><br />

colleagues to all UN agencies, international<br />

NGO’s such as CBM,<br />

FHF, HKI, Orbis, SF, SIGHT AND<br />

LIFE , <strong>and</strong> our good friends, who<br />

have given Vietnam such valuable<br />

<strong>and</strong> effective assistance in our<br />

Blindness Prevention Program<br />

for so many years.<br />

Continuing nutrition education by the Youth<br />

Volunteer Group, Nepal<br />

Ashish Sharma, Youth Volunteer Group (YVG), Banepa, Kavrepalanchok, Kathm<strong>and</strong>u,<br />

Nepal<br />

In SIGHT AND LIFE <strong>Newsletter</strong><br />

3/2005 (pp. 27–29) we reported<br />

on the nutrition education program<br />

made possible by financial<br />

<strong>and</strong> logistical support from SIGHT<br />

AND LIFE. We were very pleased<br />

when SIGHT AND LIFE gave us<br />

the opportunity to continue a<br />

similar program in another area<br />

of Nepal.<br />

About 43% of Nepal’s total population<br />

of 23.8 million is under the<br />

age of 16. Of these, 3% suffer<br />

from vitamin A deficiency xerophthalmia.<br />

Eye diseases are considered<br />

to be a vast problem which<br />

has adverse effects in the mental<br />

as well as physical development<br />

of children. This gave us the incentive<br />

to continue this Nutrition<br />

Education Campaign.<br />

Despite the fact that the National<br />

Vitamin A Program for the prevention<br />

of vitamin A deficiency has<br />

been ongoing for many years<br />

now (editor: see SIGHT AND LIFE<br />

<strong>Newsletter</strong> 3/1995 pp. 12–13),<br />

it seems that knowledge in the<br />

population is still not sufficient.<br />

Therefore the YVG started this<br />

education effort in various areas<br />

to make people aware of their<br />

own nutrition situation <strong>and</strong> that<br />

of their children.<br />

From January to March 2006 this<br />

“Nutrition Education Campaign”<br />

was carried out in the area of<br />

the Kavrepalanchok district. The<br />

direct beneficiaries were 559 children<br />

<strong>and</strong> 275 pregnant <strong>and</strong> nursing<br />

mothers <strong>and</strong> their families.<br />

Objectives, methods <strong>and</strong> procedures<br />

were very similar to the<br />

previous program, with improvements<br />

where possible (see <strong>Newsletter</strong><br />

3/2005)<br />

Children’s eye screening<br />

The eyes of a total of 559 children<br />

were examined by a senior ophthalmic<br />

assistant for any signs or<br />

symptoms of VAD. All affected<br />

children were given a vitamin A<br />

capsule <strong>and</strong> some of them were<br />

referred to the Nepal Eye Hospital.<br />

Twenty-six children (4.6%)<br />

aged 5 months to 5 years were<br />

found to have eye symptoms (XN<br />

6; X1B 10: XN+X1B 7; X2+X3 3).<br />

Conclusions <strong>and</strong><br />

recommendation<br />

There has been an increase in<br />

knowledge about vitamin A rich<br />

food, vitamin A deficiency diseases,<br />

blindness etc. amongst<br />

mothers <strong>and</strong> caretakers, <strong>and</strong><br />

those identified with eye symptoms<br />

received appropriate care.<br />

The evaluation showed a very<br />

positive impact on the people<br />

with regard to knowledge.<br />

Although there has been a positive<br />

response to the program<br />

in the areas where it is running<br />

– with an increase in knowledge<br />

of vitamin A rich food <strong>and</strong> ways of<br />

consuming it, as well as more information<br />

about VAD – this short<br />

program of three months cannot<br />

solve the problem completely. If<br />

the people do not take the initiative<br />

themselves the problem will<br />

never be solved.<br />

Outsiders like us are ever ready<br />

to work in this field to increase<br />

people’s awareness, but there are<br />

many reasons why we cannot do<br />

this work for very long. So if we<br />

support <strong>and</strong> prepare some peer<br />

groups among the local people<br />

then they can work in a better <strong>and</strong><br />

more sustainable way.

P Manoharan, Project Director, Pache Trust, Madurai, Tamil Nadu, India<br />

Introduction<br />

The People’s Association for<br />

Community Health Education<br />

Trust (PACHE Trust) is a grassroots<br />

level non-profit <strong>and</strong> nongovernmental<br />

organization functioning<br />

for the dedicated cause<br />

of uplifting the rural poor with<br />

due emphasis on the betterment<br />

of women <strong>and</strong> children. The organization<br />

is also involved in a<br />

considerable number of HIV/AIDS<br />

prevention projects among the<br />

highly vulnerable groups. The<br />

organization has been involved<br />

in many projects involving community<br />

health, women’s empowerment<br />

etc.<br />

PACHE Trust, in joint venture with<br />

SIGHT AND LIFE, has been engaged<br />

in the prevention of vitamin<br />

A deficiency disorders (VADD) in<br />

recent years. The SIGHT AND<br />

LIFE <strong>Newsletter</strong> 1/20<strong>02</strong> contained<br />

an article from PACHE Trust (pp.<br />

20–21), <strong>and</strong> pictures of program<br />

activities were included in <strong>Newsletter</strong><br />

3/2004, p. 48. The project<br />

was launched in districts where<br />

children were found to be prone<br />

to deficiency diseases. It is one<br />

of the most significant projects in<br />

Tamil Nadu addressing the needs<br />

of children below 10 years of age.<br />

VADD are a major health concern<br />

among children, especially the<br />

rural poor. The project has been<br />

attaining increasing success with<br />

every passing year. The community<br />

has been sensitized <strong>and</strong> there<br />

is visibly increased awareness on<br />

the prevention of VADD.<br />

The goals, to treat <strong>and</strong> prevent<br />

VADD, have not changed over<br />

the years. The methods of communication,<br />

training <strong>and</strong> of raising<br />

attention for precautionary measures<br />

have been developed <strong>and</strong><br />

refined. More attention is now<br />

given to pregnant <strong>and</strong> lactating<br />

mothers.<br />

Achievements include reaching<br />

more children, the orientation of<br />

school teachers, regular school<br />

visits, regular vitamin A supplementation<br />

(vitamin A capsules),<br />

health camps, giving attention<br />

to people with other diseases<br />

<strong>and</strong> a strong collaboration with<br />

authorities.<br />

Awareness of self-help<br />

groups (SHG)<br />

The SHGs play a major role in<br />

the effective implementation of<br />

project activities because women<br />

are highly involved. It is the SHGs<br />

who disseminate the new messages<br />

<strong>and</strong> developmental measures<br />

to the community, especially<br />

to the women. Besides dissemination<br />

of information regarding<br />

vitamin A, other micronutrients,

macronutrients <strong>and</strong> the importance<br />

of a balanced diet were<br />

emphasized.<br />

During the past year 30 orientation<br />

seminars were conducted<br />

for SHG leaders (many of them<br />

are women) representing about<br />

900 groups. The training had a<br />

wholesome effect <strong>and</strong> served its<br />

purpose. The members of the<br />

SHGs are trained well <strong>and</strong> the<br />

success of the project relies on<br />

them as they have to bring the<br />

group together <strong>and</strong> to pass on<br />

the messages.<br />

Kitchen gardening<br />

This proved to be an interesting<br />

<strong>and</strong> suitable approach. Besides<br />

the general public, school children<br />

showed much interest in planting<br />

saplings beside the school <strong>and</strong> in<br />

other places. It was demonstrated<br />

how to collect seeds <strong>and</strong> how to<br />

h<strong>and</strong>le them to grow plants.<br />

Cultural programs<br />

The street plays <strong>and</strong> other activities<br />

have their own impact on the program.<br />

In this way even illiterate people<br />

can underst<strong>and</strong> the concept.<br />

Conclusions<br />

The program is going well <strong>and</strong><br />

developing in the right direction.<br />

There are more people to<br />

reach <strong>and</strong> resources are never<br />

enough. We thank all those who<br />

contributed to the success of the<br />

program especially all the active<br />

participants, school children,<br />

women <strong>and</strong> SHG leaders, but<br />

also organizations like SIGHT<br />

are essential. We hope to be able<br />

Centre (PEEC), Velgode, Kurnool District, Andhra Pradesh, India.<br />

Introduction<br />

PEEC considers itself privileged<br />

to work h<strong>and</strong> in h<strong>and</strong> with SIGHT<br />

AND LIFE. The support of SIGHT<br />

AND LIFE over the past years<br />

has made it possible to develop<br />

a significant health program covering<br />

most of the state of Andhra<br />

Pradesh. Reports about PEEC<br />

activities were included in SIGHT<br />

AND LIFE <strong>Newsletter</strong>s 3/2001<br />

(pp. 34–35) <strong>and</strong> 1/2004 (p. 17).<br />

The program is a continuation<br />

from previous years <strong>and</strong> it is key<br />

to sustainability through education,<br />

counseling <strong>and</strong> distribution<br />

of vitamin A capsules. The main<br />

target groups are community <strong>and</strong><br />

grass-roots people who are given<br />

adequate knowledge to make use<br />

of the available natural resources<br />

to overcome nutritional problems<br />

in growing children.<br />

Main activities<br />

PEEC is a center for the coordination<br />

of activities for more<br />

than 110 local NGOs, <strong>and</strong> even<br />

more NGOs attend information<br />

meetings. Orientation <strong>and</strong> training<br />

programs for NGO leaders<br />

on the importance of vitamin A<br />

deficiency (VAD) are offered, as<br />

well as awareness camps on<br />

eye care for schoolchildren, slum<br />

children <strong>and</strong> their parents. The<br />

vitamin A capsules from SIGHT<br />

AND LIFE are not only important<br />

for the immediate prevention of<br />

deficiency, they are also an important<br />

tool to raise awareness<br />

<strong>and</strong> to reach people <strong>and</strong> finally to<br />

communicate the message about<br />

the importance of the vitamin A<br />

<strong>and</strong> the various kinds of fruits,<br />

vegetables <strong>and</strong> other foods containing<br />

vitamin A <strong>and</strong> provitamin<br />

A carotenoids.<br />

The financial support from SIGHT<br />

AND LIFE allows us to give small<br />

financial contributions to some<br />

NGOs for their activities <strong>and</strong> to<br />

start vegetable gardens. PEEC<br />

prepares <strong>and</strong> prints resource materials<br />

like wall posters, h<strong>and</strong>bills,<br />

stickers <strong>and</strong> booklets etc. in the<br />

local language. Assistance was<br />

offered to tsunami victim families<br />

using a special grant from SIGHT<br />

AND LIFE.<br />

Training programs<br />

During 2005 only three training<br />

programs were conducted. They<br />

were attended by representatives<br />

from 85, 90 <strong>and</strong> 66 NGOs.<br />

Awareness programs<br />

Some of the partner NGOs are selected<br />

for this program to spread<br />

the message on the need for<br />

vitamin A <strong>and</strong> its relation to eye<br />

care. These NGOs visit schools,<br />

slum areas, integrated child development<br />

schools <strong>and</strong> women’s<br />

groups, <strong>and</strong> enlighten them about<br />

the importance of healthy nutrition.<br />

Also they inform the children,<br />

their parents <strong>and</strong> neighbors<br />

about the various vegetables <strong>and</strong><br />

fruits. These NGOs also distribute<br />

resource materials like wall posters,<br />

h<strong>and</strong>bills, UNICEF materials<br />

<strong>and</strong> booklets, <strong>and</strong> they paste wall<br />

posters on the walls of important

public places in the villages. It<br />

is very effective <strong>and</strong> people are<br />

interested in participating in such<br />

meetings.<br />

A new method of awareness<br />

campaigning is carried on in the<br />

districts of Guntur <strong>and</strong> Krishna. In<br />

this the local NGOs have formed<br />

into a committee <strong>and</strong> engaged a<br />

motor vehicle with all our slogans,<br />

symbols of vitamin A deficiency<br />

<strong>and</strong> eye care which moves from<br />

village to village. The local leaders<br />

in the villages have taken on<br />

the responsibility of spreading the<br />

messages.<br />

Vegetable gardens<br />

This is an innovative method to<br />

ensure that vegetables with a<br />

rich carotenoid content, including<br />

green leafy vegetables, are made<br />

available to people in the local<br />

markets. For this we have given<br />

some assistance to women farmers<br />

<strong>and</strong> women’s self-help groups<br />

to grow vegetables with more<br />

provitamin A. This is a revolving<br />

fund <strong>and</strong> the partner NGOs will<br />

be revolving this money among<br />

the women’s groups. This has<br />

proved very successful in some<br />

districts, like Chittoor, Prakasam<br />

<strong>and</strong> Guntur.<br />

PEEC’s sister organization, the<br />

Rural Development Society, distributes<br />

vegetable seeds as part<br />

of the kitchen gardens scheme<br />

for better nutrition among children.<br />

This program is linked with<br />

vitamin A deficiency prevention.<br />

Thous<strong>and</strong>s of families are given<br />

the vegetable seeds which they<br />

plant in kitchen gardens around<br />

their houses <strong>and</strong> use for food.<br />

So this is also indirectly supporting<br />

the eradication of vitamin A<br />

deficiency.<br />

Resource materials<br />

Wall posters are prepared <strong>and</strong><br />

printed. These are distributed<br />

to the partner NGOs for display<br />

on the walls of public places to<br />

highlight the message. This is<br />

very informative <strong>and</strong> people are<br />

very enthusiastic about it.<br />

H<strong>and</strong>bills are distributed to the<br />

public in the villages during festivals,<br />

holidays etc. They are very<br />

effective. Social workers, doctors<br />

<strong>and</strong> paramedical staff appreciate<br />

them as they are another form of<br />

information material.<br />

The “SIGHT AND LIFE Guidebook<br />

on Vitamin A in Health <strong>and</strong><br />

Disease” was translated into the<br />

local language (Telugu), printed<br />

<strong>and</strong> distributed to local leaders,<br />

teachers, social workers etc.<br />

through NGOs. This book has<br />

been well received <strong>and</strong> needs to<br />

be reprinted to meet dem<strong>and</strong>.<br />

Tsunami assistance<br />

Emergency relief measures were<br />

carried out in four districts. The<br />

relief materials distributed during<br />

the disaster period consisted<br />

of food grains like rice <strong>and</strong> dhal;<br />

aluminum pots for selling fish;<br />

dress materials for saris <strong>and</strong><br />

dhotis; towels, blankets <strong>and</strong><br />

utensils; <strong>and</strong> educational materials<br />

like note books, slates etc. for<br />

schoolchildren. The aid included<br />

calcium tables <strong>and</strong> safe drinking<br />

water containers. This covered<br />

440 families altogether <strong>and</strong> 420<br />

children benefited. The tsunami<br />

victims expressed their gratitude<br />

to SIGHT AND LIFE for the help<br />

in the emergency.<br />

Conclusion<br />

On the whole, the program is<br />

continuing successfully <strong>and</strong> no<br />

major difficulties are faced. Many<br />

NGOs are interested in participating<br />

<strong>and</strong> they are asking us to hold<br />

meetings every three months.<br />

The vitamin A capsules are very<br />

attractive <strong>and</strong> many NGOs want<br />

to receive more, but we are not<br />

able to supply them because the<br />

stock is very limited. The government<br />

is not issuing the permission<br />

necessary to import the<br />

vitamin A capsules donated by<br />

SIGHT AND LIFE. The products<br />

available in the medical stores<br />

are not comparable <strong>and</strong> are very<br />

expensive. PEEC wants to reach<br />

even more people in Andhra<br />

Pradesh but due to financial <strong>and</strong><br />

resource restrictions this is not<br />

always possible.

Knowledge <strong>and</strong> perception of vitamin A<br />

deficiency in the villages of Burkina Faso<br />

Rosemary Fleury Téchoueyres, Youzondo Association, Bordeaux-Caudéran, France<br />

During missions to the north of<br />

Burkina Faso, we noticed cases<br />

of night blindness. This led us to<br />

found the Youzondo Association,<br />

whose name, in the Moré language,<br />

refers to this condition.<br />

Operation<br />

In many areas we chose to create<br />

village associations consisting of<br />

a committee of eight people <strong>and</strong><br />

two delegates per district. They<br />

meet every quarter to discuss a<br />

topic related to nutrition, communication<br />

or agriculture. Their<br />

activities are coordinated with the<br />

national Burkinabé Association<br />

for the Prevention of Youzondo.<br />

It all began under the palabras<br />

tree at Petit Samba. As usual<br />

between 1pm <strong>and</strong> 4pm we were<br />

discussing everyone’s concerns,<br />

particularly with regard to children’s<br />

health, <strong>and</strong> this was how<br />

we heard about Youzondo sickness.<br />

Action taken<br />

With the help of a student pharmacist<br />

from Ouagadougou, we<br />

studied the average composition<br />

of the diets of 80 mothers<br />

<strong>and</strong> their children by means of<br />

a questionnaire. This evaluative<br />

work also took into account levels<br />

of plasma retinol <strong>and</strong> conjunctival<br />

impression tests. The extent of vitamin<br />

A deficiency at Petit Samba<br />

was found to be a serious public<br />

health problem.<br />

The second stage was to organize<br />

a day of festive <strong>and</strong> sporting<br />

events, including a bicycle race,<br />

a football match, <strong>and</strong> a theatre<br />

performance given by Hippolyte<br />

Ouangrawa’s troupe. This show<br />

portrays a village family whose<br />

son suffers from night blindness.<br />

It describes the intervention of<br />

members of his family, the woman<br />

next door, the marabout, <strong>and</strong> the<br />

nurse at the Centre of Health <strong>and</strong><br />

Social Advancement. The subject<br />

(i.e. the dangers of vitamin A deficiency,<br />

the way to deal with it,<br />

the kinds of food which contain<br />

it etc.) is treated both accurately<br />

<strong>and</strong> humorously. Afterwards, a forum<br />

allows the audience to react,<br />

to ask questions, <strong>and</strong> to give their<br />

point of view.<br />

The third part of our approach<br />

was training. Thanks to subsidies,<br />

we were able to create health<br />

broadcasts for local radio. We<br />

also organized 3 days of training<br />

with a medical nutritionist <strong>and</strong><br />

a sociologist, aimed at nurses,<br />

district delegates, <strong>and</strong> teachers.<br />

We stressed the importance of<br />

a varied diet. We recommended<br />

orange fruits <strong>and</strong> vegetables<br />

(mangoes, papayas, carrots,<br />

<strong>and</strong> orange sweet potatoes)<br />

<strong>and</strong> vegetables with dark green<br />

leaves (leaves of sorrel, niebe <strong>and</strong><br />

baobab). Other foods, however,<br />

are not so readily available: eggs,<br />

liver, milk <strong>and</strong> related products,<br />

<strong>and</strong> red palm oil, the supply of<br />

which has been stopped from<br />

Ivory Coast.<br />

Results<br />

Three hundred <strong>and</strong> sixty-five<br />

mango trees have been planted in<br />

Petit Samba. At Bonou, we have<br />

a one-hectare market garden.<br />

Two other villages are about to<br />

begin growing for the market.<br />

At Tiogo, a dispensary has been<br />

built. Schools are circulating<br />

health information thanks to the<br />

educational materials sent by<br />

SIGHT AND LIFE.<br />

Conclusions<br />

We are preparing a 5-year scientific<br />

evaluation of the effect of<br />

awareness-raising at the village<br />

of Petit Samba for 2007.<br />

We would like to thank the many<br />

people who help us to do our job,<br />

whether through work, donations,<br />

or in other ways.

Vitamin A deficiency <strong>and</strong> malnutrition among<br />

Sudanese children admitted to an urban hospital<br />

Academy of Medical Sciences <strong>and</strong> Technology, Khartoum, Sudan<br />

Protein energy malnutrition (PEM)<br />

constituted about 10% of total<br />

admissions to the Academy<br />

Charity Teaching Hospital (ACTH)<br />

during the period between December<br />

2004 <strong>and</strong> December<br />

2005. Xerophthalmia was found<br />

more often in children with malnutrition<br />

or after measles infection,<br />

<strong>and</strong> in children from displaced<br />

families, among nomads <strong>and</strong> in<br />

orphans.<br />

During the above period a total<br />

number of 1,420 children under<br />

five years were admitted to the<br />

nutrition ward of ACTH, 13 of<br />

whom had different degrees of<br />

xerophthalmia. Two children developed<br />

keratomalacia, which in<br />

one was bilateral <strong>and</strong> left the child<br />

totally blind. The second child<br />

lost one eye, which had ruptured<br />

at home before admission. All<br />

children admitted were given 2<br />

doses of vitamin A in dosages<br />

recommended by the WHO. This<br />

was adopted as a routine on the<br />

PEM ward. We thank SIGHT AND<br />

LIFE for providing the vitamin A<br />

capsules.<br />

The initial vitamin A level in Sudanese<br />

children showed wide<br />

variation, but the important fact<br />

was that about 42% of them were<br />

below 40 µg/100ml, <strong>and</strong> 20%<br />

were well below 20 µg/100ml.<br />

This is a level which predisposes<br />

children to xerophthalmia <strong>and</strong><br />

blindness. 10 days after vitamin<br />

A supplementation all children<br />

showed a significant rise in serum<br />

vitamin A to protective levels of<br />

above 40 µg/100ml.<br />

The National Nutritional Programs<br />

maintain supplementation of vitamin<br />

A at a community level. They<br />

conduct home-to-home visits as<br />

part of an EPI team for immunization<br />

to eradicate poliomyelitis.<br />

Vitamin A is supplemented twice<br />

a year in doses recommended by<br />

the WHO.<br />

The fight against vitamin A deficiency at<br />

Ouassa-Beket, Benin<br />

Jeremie Orou, Fondation pour l’Aide et l’Autopromotion à la Base en Matière<br />

In 2005 FAABA, in collaboration<br />

with the Ouassa community<br />

centre, completed three major<br />

projects to combat vitamin A<br />

deficiency:<br />

• A campaign to distribute<br />

vitamin A<br />

• Nutritional education of mothers<br />

<strong>and</strong> caregivers<br />

• Cultivation of vegetables by the<br />

women<br />

Campaign to distribute<br />

vitamin A<br />

This campaign was announced<br />

by the town crier, <strong>and</strong> publicized<br />

on local radio. On 14 October<br />

2005, over 500 children aged<br />

between 6 months <strong>and</strong> 5 years<br />

were seen, <strong>and</strong> each received a<br />

capsule.<br />

Nutritional training<br />

We organized two training sessions<br />

for mothers, <strong>and</strong> especially<br />

gr<strong>and</strong>mothers who take care of<br />

the children after weaning. The<br />

latter are often illiterate <strong>and</strong> the<br />

guardians of traditional taboos<br />

surrounding food. We showed<br />

these women the various foods<br />

(for growth, energy <strong>and</strong> protection)<br />

using posters which stress

the importance of yellow <strong>and</strong> redcolored<br />

foods rich in vitamin A.<br />

Cultivation of vegetables<br />

After the training sessions by<br />

our agents, the women of Beket<br />

decided to start a garden for the<br />

cultivation of vegetables, especially<br />

leafy vegetables. This initiative<br />

will allow the enrichment of<br />

children’s diets, <strong>and</strong> will provide<br />

them with a good source of vitamins<br />

<strong>and</strong> minerals.<br />

Conclusion<br />

The success of our operation has<br />

encouraged us to continue in<br />

2006. We even plan to bring in an<br />

ophthalmic specialist to diagnose<br />

the population in our local area.<br />

We would like to thank SIGHT<br />

AND LIFE for their help with regard<br />

to the capsules <strong>and</strong> educational<br />

materials.<br />

Introduction<br />

We are glad to be able to continue<br />

our work in mitigating micronutrient<br />

deficiencies <strong>and</strong> related<br />

dangers as well as to contribute<br />

to the improved nutrition of all<br />

those participating in our activities.<br />

The continued support<br />

of SIGHT AND LIFE in the form<br />

of financial assistance, as well<br />

as with educational materials<br />

<strong>and</strong> the links opened to other<br />

organisations were essential for<br />

our work within Rongo <strong>and</strong> its<br />

neighboring regions, which is<br />

timely <strong>and</strong> relevant. Thus it is in<br />

keeping with the overall mission<br />

of the group, i.e. to holistically<br />

enhance, foster, promote, <strong>and</strong><br />

strengthen socio-economic opportunities<br />

of rural women <strong>and</strong><br />

children. Health-related issues<br />

including nutrition remain the top<br />

priority of the group. We strongly<br />

believe that health is not only the<br />

absence of ills but also the fight<br />

for the fullness of life, a life free<br />

from micronutrient deficiencies.<br />

Nutrition activities<br />

Vitamin A capsules received from<br />

SIGHT AND LIFE were administered<br />

to 3,673 children below five<br />

years of age. About 27 days were<br />

spent on this exercise. The envisaged<br />

outcome of this exercise<br />

was to improve retinol levels in<br />

children under five <strong>and</strong> to reduce<br />

episodes of night blindness,<br />

acute VAD <strong>and</strong> related disorders,<br />

<strong>and</strong> other VAD-related ailments<br />

among children. Rongo <strong>and</strong> its<br />

neighboring regions, such as<br />

Sakwa, Kamagambo, R<strong>and</strong>ung,<br />

Opapo, Migori, etc. benefited.<br />

On various occasions RWG<br />

distributed about 5.58 tons of<br />

foodstuffs rich in vitamin A. Such<br />

vegetables as cabbage, sukumawiki<br />

(kale), carrots, kiukamba,<br />

etc. were distributed to women<br />

of childbearing age <strong>and</strong> children<br />

of five years <strong>and</strong> under. Approximately<br />

1,500 persons benefited<br />

from this program. Many of the<br />

women reached were also trained<br />

in how to prepare vegetables<br />

without destroying their nutritious<br />

value.<br />

About 63 persons have been<br />

trained so far. During such training,<br />

participants are taught how<br />

to prepare foods without destroying<br />

vital micronutrients. Demonstrations<br />

on how to prepare such<br />

foods were also conducted. Most<br />

women at the time of the training

NEWSLETTER 2/2006<br />

were at least breast-feeding their<br />

babies. It was quite encouraging<br />

to see some of these women taking<br />

notes very seriously during<br />

the demonstrations.<br />

A wide range of training techniques<br />

<strong>and</strong> tools were used, such<br />

as group-focused discussions,<br />

roleplay, case study, brainstorming,<br />

demonstrations, lectures,<br />

etc. The training emphasized the<br />

involvement of schoolchildren as<br />

key informants <strong>and</strong> educators<br />

both at family <strong>and</strong> community<br />

levels. Participants were informed<br />

about strategies to involve children,<br />

such as drawing competitions,<br />

debates, poems, etc.<br />

Eye health training<br />

<strong>and</strong> door-to-door eye<br />

screening<br />

Due to ever-increasing complaints<br />

about eye-health-related problems<br />

by community members,<br />

<strong>and</strong> childhood blindness due to<br />

VAD, this training was a necessary<br />

part of the effort of RWG.<br />

Five individuals were selected<br />

for further training on the basis<br />

of their ability to deliver services<br />

to the communities, reputation<br />

<strong>and</strong> working relationship within<br />

the communities. They were fully<br />

aware of the people <strong>and</strong> their<br />

needs. Two resource persons invited<br />

from Tanzania facilitated the<br />

one-week intensive training.<br />

Training on poultry<br />

keeping<br />

The training was intended to increase<br />

local participation in direct<br />

production of locally available<br />

foods rich in vitamin A. To attend<br />

the training it was required that<br />

participants were able to start<br />

<strong>and</strong> sustain chicken-rearing to required<br />

st<strong>and</strong>ards which would be<br />

overseen by a qualified veterinary<br />

officer. From the local communities<br />

56 women were trained by<br />

veterinary officers from the Ministry<br />

of Livestock Development on<br />

how to start <strong>and</strong> manage a small<br />

poultry farm for family <strong>and</strong> other<br />

domestic purposes. The training<br />

included visits to commercial<br />

poultry farmers.<br />

Conclusions<br />

We are convinced that our efforts<br />

are going in the right direction.<br />

However, more is necessary in<br />

training <strong>and</strong> communication as<br />

well as in local production of<br />

healthy food through food production<br />

initiatives <strong>and</strong> encouragement<br />

of agro-business.<br />

We cannot finish this report without<br />

noting that at present the efforts<br />

are not sufficient to manage<br />

VAD <strong>and</strong> other micronutrient deficiencies.<br />

In this sense we have<br />

to say the struggle continues<br />

<strong>and</strong> we hope for further support,<br />

including continuing support from<br />

SIGHT AND LIFE.

SIGHT AND LIFE visited Pohnpei<br />

in April 2006 to film a documentary<br />

about nutrition problems in<br />

Micronesia <strong>and</strong> the efforts underway<br />

for alleviating these problems.<br />

Their visit was coordinated<br />

by the Isl<strong>and</strong> Food Community of<br />

Pohnpei.<br />

Klaus Kraemer, Head of SIGHT<br />

AND LIFE, <strong>and</strong> Thomas Breisach,<br />

Deputy Head of the DSM Nutritional<br />

Products Communications<br />

Section, made up the SIGHT<br />

AND LIFE team. They were in<br />

Pohnpei from 21 to 27 April, 2006.<br />

Ulla Lohmann, filmmaker, <strong>and</strong> her<br />

camera assistant Markus Hain<br />

were engaged as consultants<br />

<strong>and</strong> were in Pohnpei from 10 to<br />

27 April, 2006.<br />

The purpose of the film is to produce<br />

a documentary about global<br />

nutrition problems, including micronutrient<br />

deficiencies <strong>and</strong> nutrition-<br />

<strong>and</strong> lifestyle-related chronic<br />

diseases such as diabetes, heart<br />

disease <strong>and</strong> cancer. Dr. Kraemer<br />

pointed out that Pohnpei is an<br />

example of a country having a<br />

double burden of malnutrition: the<br />

problem of micronutrient deficiencies<br />

such as vitamin A deficiency,<br />

<strong>and</strong> the problem of overweight<br />

<strong>and</strong> chronic diseases. He said,<br />

The SIGHT AND LIFE team (from left): Markus Hain, Ulla<br />

Lohmann, Klaus Kraemer, Thomas Breisach.<br />

“No one would expect an isl<strong>and</strong><br />

in the Pacific to have the nutrition<br />

problems of both developing <strong>and</strong><br />

industrialized countries.”<br />

Over half of Pohnpei’s children<br />

have vitamin A deficiency, a disorder<br />

leading to increased infection<br />

<strong>and</strong> mortality. Coupled with<br />

this, there are serious problems<br />

of obesity <strong>and</strong> chronic diseases<br />

such as diabetes, heart disease<br />

<strong>and</strong> cancer in Pohnpei, leading<br />

to higher rates of mortality <strong>and</strong><br />

great suffering among families<br />

<strong>and</strong> individuals.<br />

The group filmed the beauty<br />

spots of Pohnpei, including the<br />

lush Pohnpei l<strong>and</strong>scape, the historical<br />

site of Nan Madol, water<br />

scenes, <strong>and</strong> cultural events, first<br />

portraying aspects of the paradise<br />

concept that many people<br />

in other parts of the world have<br />

about life on a Pacific isl<strong>and</strong>.<br />

The team then filmed aspects<br />

of the real-life situation relating<br />

to food, nutrition <strong>and</strong> health,<br />

<strong>and</strong> efforts to improve the nutritional<br />

At the farewell luncheon.<br />

At a farewell luncheon for the<br />

SIGHT AND LIFE team, Dr. Kraemer<br />

was invited to give a few<br />

words of advice to IFCP <strong>and</strong> their<br />

efforts to improve health <strong>and</strong> nutrition<br />

in Pohnpei. The IFCP board<br />

members <strong>and</strong> all present were<br />

very touched by his insight. His<br />

three points were as follows:<br />

• Think about quantities of food<br />

eaten. There is a serious problem<br />

of overweight <strong>and</strong> obesity<br />

in Micronesia. Fresh local<br />

foods are generally good, but<br />

even local foods can lead to<br />

overweight if eaten in excess or<br />

if prepared in unhealthy ways<br />

(adding sugar, frying or using<br />

excess fat).<br />

• Focus on the youth. They are<br />

the future. Their habits are not<br />

yet fully set.<br />

• Remember that not all imported<br />

foods are unhealthy.<br />

There are some imported foods<br />

available that are fortified with<br />

micronutrients. Remember to<br />

read the labels!!<br />

IFCP has already started working<br />

on this advice, talking about<br />

quantities eaten <strong>and</strong> working<br />

with the youth. Also, an email<br />

message was sent out to the<br />

IFCP email network to share information<br />

about fortified instant<br />

noodles. Although many instant<br />

noodles sold in Pohnpei contain<br />

no vitamin A, there are some<br />

br<strong>and</strong>s that have been fortified<br />

<strong>and</strong> contain up to 30% of the<br />

estimated daily requirements. If<br />

consumers plan to eat instant<br />

noodles, they could choose the<br />

fortified br<strong>and</strong>s in order to get a<br />

more nutritious food. The same<br />

message is now being relayed<br />

to community members in small<br />

workshops, showing actual examples<br />

of the fortified <strong>and</strong> nonfortified<br />

br<strong>and</strong>s.<br />

SIGHT AND LIFE<br />

A digest of recent literature<br />

Donald S McLaren*<br />

Introduction<br />

Mention has been made in several<br />

recent issues of the <strong>Newsletter</strong> of<br />

the shift in topic that has gradually<br />

taken place in the retinoid <strong>and</strong> carotenoid<br />

literature. Basic laboratory<br />

research has far outstripped human<br />

community <strong>and</strong> clinical studies<br />

which are clearly of more concern to<br />

most readers of the literature digest.<br />

As a result, abstracts of basic studies<br />

have had to be strictly limited<br />

because of restricted space. An<br />

attempt has been made to include<br />

those basic studies that seem to be<br />

of greatest relevance, but this has<br />

hitherto left a large number of chosen,<br />

relevant papers excluded.<br />

A number of readers have expressed<br />

their appreciation of the<br />

way in which their attention has<br />

been drawn by a quick scan of the<br />

literature digest to topics of special<br />

interest to them. This would clearly<br />

be all the more valuable if the coverage<br />

of the new literature could be<br />

made more complete. Consequently,<br />

this issue contains an Appendix<br />

after the main abstracts. This has<br />

been compressed to provide only<br />

essential information on the papers<br />

it covers in order to include as many<br />

as possible. The title (sometimes<br />

abbreviated) is in bold as usual,<br />

followed by the name <strong>and</strong> initials of<br />

the first author <strong>and</strong> finally the journal<br />

reference. Abbreviated abstracts<br />

have been grouped according to<br />

topic as this seemed the best way<br />

for readers, if they so wish, to make<br />

some selection. With use of the<br />

Internet this should give access to<br />

more complete information. It would<br />

be helpful to the editor to learn if this<br />

change is appreciated.<br />

14,110 mother-infant pairs were enrolled.<br />

Neither maternal nor neonatal<br />

vitamin A supplementation significantly<br />

affected postnatal MTCT<br />

reasons the results of this trial raises<br />

concern about universal maternal or<br />

Mastitis is an increased mammary<br />

permeability <strong>and</strong> is frequently accompanied<br />

by bacterial infection.<br />

Supplementation with vitamin A<br />

reduces the prevalence of bacterial<br />

mastitis <strong>and</strong> the inflammatory<br />

response. However, studies<br />

of mother-to-child transmission in<br />

HIV-positive women have shown<br />

no reduction with vitamin A supplementation.<br />

One study in Tanzania<br />

reported an increase. Possible<br />

mechanisms for this unexpected<br />

result are being investigated. One<br />

way may be the paracellular entry<br />

of leukocytes affected by retinoic<br />

acid into breast milk.<br />

This review follows an international<br />

meeting in Bangladesh on this<br />

subject. Oral rehydration has been<br />

successfully pursued for more than<br />

three decades <strong>and</strong> now WHO <strong>and</strong><br />

UNICEF have introduced a new<br />

reduced osmolarity formulation<br />

(WHO/UNICEF Joint Statement.<br />

Clinical management of acute diarrhoea.<br />

2004). In addition they recommend<br />

the therapeutic use of zinc<br />

for 10–14 days at a dose of 10 mg<br />

daily in infants under 6 months <strong>and</strong><br />

20 mg daily in older children. There<br />

is no mention of vitamin A. Before<br />

the beneficial effect of zinc supplementation<br />

in acute diarrhea was<br />

discovered there were many reports<br />

of the efficacy of vitamin A. A recent<br />

reappraisal (see two abstracts below)<br />

reported even greater benefit<br />

of vitamin A than when analysis<br />

was made previously. Furthermore,<br />

there is growing acceptance of the<br />

concept that diarrhea is often an<br />

integral part of vitamin A deficiency<br />

<strong>and</strong> the need for vitamin A replacement<br />

is evident. Other recent documents,<br />

especially in connection with<br />

achievement of some of the Millennium<br />

Goals have always bracketed<br />

together vitamin A <strong>and</strong> zinc in this<br />

context. This issue requires urgent<br />

attention; data supporting vitamin A<br />

supplementation for treatment <strong>and</strong><br />

prevention of diarrheal diseases are<br />

available.<br />

The pathological effects of malaria<br />

in pregnancy are believed to be due<br />

to the sequestration of parasites in<br />

the placenta, mediated by binding<br />

of variant surface antigens (VSA)<br />

expressed on the surface of P.<br />

falciparum-infected red blood cells<br />

to placental chondroitin sulfate A<br />

(CSA). Vitamin A supplementation<br />

was accompanied by reduced<br />

levels of anti-VSACSA antibodies<br />

<strong>and</strong> may reflect reduced placental<br />

parasitemia.<br />

Attention is drawn in this review to<br />

the neglected importance of the<br />

acute phase response (APR) in the<br />

assessment of nutritional status of a<br />

number of micronutrients. Vitamin A,<br />

iron <strong>and</strong> zinc have been most extensively<br />

studied in this regard but other<br />

vitamins <strong>and</strong> elements are likely to<br />

be implicated. The phenomenon is<br />

widespread, especially in childhood,<br />

as even subclinical infection <strong>and</strong> inflammation<br />

are capable of reducing<br />

the concentration of the nutrient in<br />

the serum <strong>and</strong> the effect is evident<br />

within as little as 24 hours. The<br />

overall effect is to give the impression<br />

that deficiency levels are more<br />

widespread than they really are.<br />

Attempts are being made to devise<br />

<strong>and</strong> introduce correction values for<br />

routine application.<br />

been implicated in the death of<br />

had an increased rate of rod-mediated<br />

dark adaptation in older patients<br />

who were in the early stages<br />

This highly significant research is<br />

based, as is so often the case, on<br />

a simple idea developed in one area<br />

<strong>and</strong> neglected in another. Vitamin A<br />

deficiency reduces RBP (retinolbinding<br />

protein) but not TTR (transthyretin).<br />

Inflammation, even at a<br />

sub-clinical level, reduces both RBP<br />

<strong>and</strong> TTR <strong>and</strong> increases C-reactive<br />

protein, an acute phase response<br />

component. In 79 ELBW infants<br />

higher CRP <strong>and</strong> RBP/TTR molar ratio<br />

on day 28 were associated with<br />

death/bronchopulmonary dysplasia<br />

(a common association with ELBW)<br />

at 36 weeks. It was concluded that<br />

inflammation, rather than vitamin A<br />

deficiency, was the cause of low<br />

serum retinol levels. (In other words,<br />

this suggests that the considerable<br />

amount of research leading to the<br />

current practice of administering<br />

routinely intramuscular vitamin A<br />

to ELBW infants is fallacious in that<br />

no true state of vitamin A deficiency<br />

exists, but only a misleadingly low<br />

serum retinol attributable to inflammation).<br />

Letters to the editor<br />

Fortification of edible<br />

oil with vitamin A <strong>and</strong><br />

carotene<br />

Dear Sir<br />

Your SIGHT AND LIFE <strong>Newsletter</strong><br />

1/2006 included a paper on<br />

vitamin A fortification of edible oil<br />

as a cost-effective <strong>and</strong> sustainable<br />

intervention program to supply<br />

vitamin A to the population. It<br />

was good to know that vitamin A<br />

fortification of edible soybean<br />

oil was voluntarily implemented<br />

in Bangladesh: I hope the same<br />

will happen in other countries. In<br />

the 1990s our Brazilian nutrition<br />

group started to study <strong>and</strong> to put<br />

together scientific data to support<br />

the utilization of cooking oil as a<br />

vitamin A <strong>and</strong> carotene carrier<br />

to prevent vitamin A deficiency.<br />

One of the main obstacles for its<br />

use was the prestige of other vehicles<br />

like wheat flour <strong>and</strong> sugar,<br />

<strong>and</strong> the fact that vitamin A, being<br />

heat-sensitive, could not be<br />

added to a cooking ingredient.<br />

Our first published paper (1991)<br />

on the subject studied the stability<br />

of vitamin A added to refined<br />

soybean oil during cooking <strong>and</strong><br />

storage. It was shown that, after<br />

6 – 9 months of storing the oil in<br />

sealed metal cans at room temperature,<br />

the content of the vitamin<br />

A was still 99% of the original<br />

value. In open cans stored in a<br />

light environment the vitamin A<br />

content starts to decrease after 6<br />

months. When the same fortified<br />

oil was used for the preparation<br />

of local rice <strong>and</strong> bean foods,<br />

boiling or under pressure, levels<br />

from 88% to 99% of the original<br />

vitamin A values were found.<br />

Levels of vitamin A in potatoes<br />

deep fried in vitamin A-fortified<br />

cooking oil at high temperature<br />

decreased slightly. Repeated<br />

frying of the same fortified oil at<br />

high temperature decreased the<br />

amount of vitamin A incorporated<br />

into the potatoes (1). St<strong>and</strong>ard<br />

biological trials on vitamin A<br />

depleted rats fed non-fortified<br />

<strong>and</strong> A-fortified cooking oil confirmed<br />

its bioavailability based<br />

on plasma <strong>and</strong> liver vitamin A<br />

levels (2). A final confirmation of<br />

the bio-utilization of the vitamin A<br />

fortified oil was obtained in normal<br />

human subjects by adding<br />

fortified oil to salad or to cooked<br />

food <strong>and</strong> measuring the postabsorption<br />

plasma peak rise <strong>and</strong><br />

the area under the A-serum test<br />

curve. A control group receiving<br />

non-fortified oil did not show<br />

changes in comparison to their<br />

fasting plasma serum A levels,<br />

but the postpr<strong>and</strong>ial A plasma<br />

level increased threefold in subjects<br />

who received fortified oil<br />

(3). With these scientific studies<br />

we have provided a background<br />

of necessary scientific support<br />

for the use of cooking oil as a<br />

vitamin A carrier. Other similar<br />

studies were carried out with<br />

synthetic carotene also added<br />

to soybean oil. Rats receiving<br />

diets with carotene-fortified<br />

soybean oil increased their liver<br />

vitamin A levels (4). Higher levels<br />

of plasma carotene were found<br />

when healthy adults received rice<br />

cooked with carotene-enriched<br />

soybean oil (5). We also advise<br />

mixing edible soybean <strong>and</strong> palm<br />

oil as a way to supply carotene.<br />

Although we did not explore this<br />

possibility further, it is certain to<br />

be effective. Anyway, our experimental<br />

<strong>and</strong> clinical studies support<br />

vegetable oil as an effective<br />

vehicle to supply vitamin A or<br />

carotene to the relevant population.<br />

Unfortunately our studies<br />

have not received worldwide<br />

recognition. This is a rational <strong>and</strong><br />

practical intervention <strong>and</strong> one of<br />

the best ways to supply people<br />

at community level with vitamin<br />

A <strong>and</strong> carotene. No special<br />

equipment is needed to add the<br />

vitamins – it is just adding oil to<br />

oil. The work in Bangladesh will<br />

certainly prove again that cooking<br />

oil has to be accepted <strong>and</strong> used<br />

as one of the most effective <strong>and</strong><br />

practical low-cost carriers for the<br />

control of vitamin A deficiency. I<br />

hope other countries will follow it<br />

as a voluntary or compulsory way<br />

to guarantee the necessary intake<br />

of vitamin A everywhere.<br />

Dear Sir<br />

In my letter printed in the SIGHT<br />

already expressed my thanks to<br />

SIGHT AND LIFE. Again I would<br />

like to express how helpful all the<br />

items I’m receiving are.<br />

Although we are at quite a remote<br />

place, we normally follow<br />

the national campaign to give a<br />

vitamin A capsule <strong>and</strong> a deworming<br />

tablet to all children under<br />

the age of five years every year,<br />

in December. Many health units<br />

here have benefited from this system<br />

to improve their vaccination<br />

coverage records. The provision<br />

of vaccines to all children from 9<br />

months to five years of age has<br />

increased from 68% in 2001 to<br />

87.7% in 2005. The coverage<br />

of vitamin A supplementation<br />

increased from 54% (2001) to<br />

89.4% (2005).<br />

I ask SIGHT AND LIFE to please<br />

continue with their support to<br />

Dear Sir<br />

Nkhoma is situated in a rural area<br />

of Central Malawi with a population<br />

of predominantly subsistence<br />

farmers. We serve some of the<br />

poorest people in the world. I was<br />

posted to Nkhoma six years ago<br />

by the Christoffel Blind Mission<br />

International (CBMI) to implement<br />

a VISION 2<strong>02</strong>0 Program.<br />

Malawi has a population of over<br />

11 million with over 100,000<br />

blind. Vitamin A deficiency, cataract<br />

<strong>and</strong> traditional eye medicine<br />

account for a high proportion of<br />

blindness in children. There are<br />

seven ophthalmologists working<br />

in Malawi <strong>and</strong> I am the only one<br />

working in a Mission Hospital.<br />

During 2005 a total of 9,865 cataract<br />

operations were carried out<br />

in Malawi. Nkhoma accounted<br />

for 45% of this total. Also, the<br />

number of outpatients increased<br />

by more than five times in recent<br />

years (2005: 23,077)<br />

The patients are brought to<br />

Nkhoma <strong>and</strong> returned home<br />

in the Eye Department vehicle,<br />

operated on <strong>and</strong> provided with<br />

meals, all free of charge. We are<br />

dedicated to providing a high<br />

volume <strong>and</strong> high quality service.<br />

This has been achieved by the<br />

excellent team work <strong>and</strong> dedication<br />

of my 27 full time Malawian<br />

staff. I thank my staff <strong>and</strong> others<br />

in Malawi <strong>and</strong> around the world<br />

who support us.<br />

We are receiving financial <strong>and</strong><br />

logistical support through CBMI<br />

<strong>and</strong> we are closely cooperating<br />

with the Malawi Ministry of<br />

Health <strong>and</strong> non-governmental<br />

organizations to ensure the limited<br />

resources are utilized to the<br />

maximum. We also thank SIGHT<br />

AND LIFE for the very useful<br />

vitamin A capsules. Nevertheless,<br />

problems remain such as<br />

management, construction <strong>and</strong><br />

staff problems. Also, for example,<br />

in the optical department most<br />

lenses have been out of stock for<br />

six months.<br />

Dear Sir<br />

We are very thankful for the information<br />

A capsules we have received, <strong>and</strong><br />

naturally for the financial support<br />

from SIGHT AND LIFE.<br />

We follow the global agreement<br />

on the need to combat<br />

vitamin A deficiency by applying<br />

basic strategies to increase the<br />

consumption of foods rich in<br />

vitamin A or to provide periodic<br />

vitamin A supplements to high<br />

risk groups.<br />

Public health <strong>and</strong> nutrition communities<br />

should always recognize<br />

the need to improve the vitamin A<br />

status of young children. Vitamin A<br />

supplementation as an approach<br />

is among the most cost-effective<br />

health interventions available.<br />

Therefore, as an organization, we<br />

are committed to vitamin A deficiency<br />

prevention programs.<br />

Food <strong>and</strong> Nutrition: a<br />

H<strong>and</strong>book for Namibian<br />

Volunteer Leaders<br />

The Government of the Republic<br />

of Namibia (GRN), through the<br />

Technical Co-operation Program<br />

(TCP) of the Food <strong>and</strong> Agriculture<br />

Organization of the United Nations<br />

(FAO), launched a new program<br />

called Rural Youth Clubs of<br />

Namibia (RYCN), as an outreach<br />

for the Rural Youth Development<br />

Program.<br />

This program has been designed<br />

<strong>and</strong> tested as a unique methodology<br />

for reaching large numbers of<br />

young people, living in even the<br />

most isolated rural villages of Namibia,<br />

with leadership development<br />

<strong>and</strong> organizational skills as<br />

well as non-formal education <strong>and</strong><br />

training in agriculture <strong>and</strong> related<br />

areas. It has been successfully<br />

demonstrated that the new RYCN<br />

is an effective delivery mechanism<br />

enabling rural young people,<br />

primarily those who are out of<br />

school, to gain basic knowledge,<br />

skills <strong>and</strong> experiences in agriculture,<br />

nutrition, health, environment<br />

<strong>and</strong> other essential skills<br />

for living. Education <strong>and</strong> training<br />

involves practical, activity-based<br />

learning <strong>and</strong> income-generating<br />

activities. By taking this training<br />

approach to even the most<br />

remote villages, large numbers<br />

of our youth should be empowered<br />

into making economically<br />

rewarding <strong>and</strong> satisfying lives for<br />

themselves <strong>and</strong> their families in<br />

rural Namibia.<br />

This manual is designed as a field<br />

h<strong>and</strong>book <strong>and</strong> guideline document<br />

for rural youth club leaders<br />

to enable them to employ coping<br />

strategies in nutritional activities<br />

taking into account the prevailing<br />

economic patterns in their<br />

respective communities. It was<br />

developed through participatory<br />

<strong>and</strong> experiential approaches involving<br />

the rural young people in<br />

selected communities in northern<br />

Namibia, a process that involved<br />

collaboration with other line<br />

ministries such as the Ministry<br />

of Agriculture, Water <strong>and</strong> Rural<br />

Obesity: Dietary <strong>and</strong><br />

Developmental Influences<br />

Focusing on prevention rather<br />

than treatment, Obesity: Dietary<br />

<strong>and</strong> Developmental Influences,<br />

reviews <strong>and</strong> evaluates the determinants<br />

of obesity. The book<br />

uses evidence-based research<br />

as a basis to define foods <strong>and</strong><br />

dietary behaviors that should be<br />

supported <strong>and</strong> encouraged as<br />

well as those that should be discouraged.<br />

This comprehensive<br />

review represents a critical step<br />

forward in the quest to identify<br />

feasible strategies to prevent<br />

obesity.<br />

The book describes the potential<br />

role of 26 different dietary factors<br />

<strong>and</strong> eight developmental periods<br />

in the prevention of obesity<br />

among children <strong>and</strong> adults. The<br />

dietary factors examined include<br />

macronutrients, micronutrients,<br />

specific types of foods <strong>and</strong> beverages,<br />

snack <strong>and</strong> meal patterns,<br />

portion size, parenting practices,<br />

breastfeeding, <strong>and</strong> more. The factors<br />

from each developmental period<br />

in the life cycle are examined<br />

in the context of the likelihood of<br />

obesity development. For each<br />

dietary factor <strong>and</strong> developmental<br />

period, four lines of evidence are<br />

examined: secular trends, plausible<br />

mechanisms, observational<br />

studies, <strong>and</strong> prevention trials.<br />

Providing easy access to information,<br />

the book features 38 tables<br />

that summarize observational<br />

studies, 38 graphs depicting<br />

trends in dietary intake, <strong>and</strong> nine<br />

Setting up <strong>and</strong> running a<br />

school garden<br />

Adequate nutrition <strong>and</strong> education<br />

are key to the development of children<br />

<strong>and</strong> their future livelihoods.<br />

The reality facing millions of children,<br />

however, is that these essentials<br />

are far from being met.<br />

A country’s future hinges on its<br />

youth. Yet children who go to<br />

school hungry cannot learn well.<br />

They have decreased physical<br />

activity, diminished cognitive abilities<br />

<strong>and</strong> reduced resistance to<br />

infections. Their school performance<br />

is often poor <strong>and</strong> they may<br />

drop out of school early. In the<br />

long term, chronic malnutrition<br />

decreases individual potential<br />

<strong>and</strong> has adverse affects on productivity,<br />

incomes <strong>and</strong> national<br />

development.<br />

Schools can make an important<br />

contribution to countries’ efforts<br />

to overcome hunger <strong>and</strong> malnutrition,<br />

<strong>and</strong> school gardens can<br />

help to improve the nutrition <strong>and</strong><br />

education of children <strong>and</strong> their<br />

families in both rural <strong>and</strong> urban<br />

areas.<br />

FAO promotes school gardens<br />

primarily as a platform for learning,<br />

as well as a vehicle for better<br />

nutrition. Schools are encouraged<br />

to create learning gardens that are<br />

moderate in size so that they can<br />

be easily managed by students,<br />

teachers <strong>and</strong> parents, but that<br />

also allow for the production of<br />

a variety of nutritious vegetables<br />

<strong>and</strong> fruits (<strong>and</strong> where possible,<br />

some small-scale livestock such<br />

as chickens or rabbits). Production<br />

methods are kept simple so<br />

that they can be easily replicated<br />

by students <strong>and</strong> parents at their<br />

homes.<br />

In preparing this manual, intended<br />

to assist school teachers, parents<br />

<strong>and</strong> the wider community, FAO<br />

has drawn upon experiences<br />

<strong>and</strong> best practices derived from<br />

school garden initiatives all over<br />

the world. Classroom lessons are<br />

linked with practical learning in<br />

the garden about nature <strong>and</strong> the<br />

environment, food production<br />

<strong>and</strong> marketing, food processing<br />

<strong>and</strong> preparation, <strong>and</strong> making<br />

healthy food choices.<br />

Community Nutrition<br />

A new CD-ROM intended as a<br />

teaching material resource has<br />

just been produced by Teaching-aids<br />

At Low Cost (TALC), a<br />

UK-based group, with financial<br />

support by UNICEF. It contains<br />

materials from many sources<br />

around the world. Each item<br />

(mostly produced between the<br />

years 2000 <strong>and</strong> 2005) is presented<br />

with a short explanation about<br />

its use. All contributors are listed<br />

with their contact details. Among<br />

many others, the SIGHT AND<br />

LIFE CD was useful as a resource<br />

<strong>and</strong> several SIGHT AND LIFE<br />

publications, <strong>Newsletter</strong> articles<br />

<strong>and</strong> slides are included.<br />

The introduction states: “This CD-<br />

ROM ... is intended for you if you<br />

work with resources-poor communities<br />

<strong>and</strong> are training health<br />

<strong>and</strong> other types of development<br />

workers <strong>and</strong> have limited access<br />

to nutrition-related materials,<br />

particularly if you do not have<br />

access to the Internet... Nutrition<br />

is a fast-changing world – most<br />

of us have very heavy workloads<br />

<strong>and</strong> it is difficult to keep updated<br />

with recent developments.”<br />

Ann Burgess, a nutrition consultant<br />

who worked intensively on<br />

this project, commented that the<br />

contribution from SIGHT AND<br />

LIFE was very useful. At this time<br />

5000 copies are being produced.<br />

For distribution, the priority is to<br />

get copies to target users such<br />

as health practitioners <strong>and</strong> development<br />

workers in developing<br />

countries <strong>and</strong> their trainers who<br />

have limited access to nutrition<br />

materials.<br />

To request a copy of the CD please<br />

SIGHT AND LIFE Workshop<br />

Nutritional Anemia<br />

Anemia is a major health concern<br />

in developing countries as well<br />

as in the developed world. It impairs<br />

growth <strong>and</strong> development,<br />

cognition <strong>and</strong> immune function,<br />

as well as school <strong>and</strong> work performance.<br />

Anemia affects more<br />

than two billion people worldwide,<br />

<strong>and</strong> has a negative impact<br />

on economic growth, particularly<br />

in low-income countries. Only<br />

about half of anemia is thought<br />

to be related to iron deficiency;<br />

other micronutrient deficiencies<br />

such as vitamin A, vitamin C, B-<br />

vitamins, zinc <strong>and</strong> copper as well<br />

as infections <strong>and</strong> undernutrition<br />

also play a crucial role. Guidelines<br />

for supplementation <strong>and</strong> food<br />

fortification to address anemia<br />

usually focus on iron <strong>and</strong> folic<br />

acid, however. On this account,<br />

we feel that it is timely to highlight<br />

all contributing factors in a workshop<br />

on Nutritional Anemia.<br />

Top international experts from different<br />

fields related to Nutritional<br />

Anemia have agreed to make<br />

presentations to the workshop.<br />

of Public Health Nutrition, Barcelona,<br />

28–30 September 2006<br />

(http://www.nutrition2006.com).<br />

The Nutritional Anemia workshop<br />

is planned to correspond closely<br />

with the Congress of Public<br />

Health Nutrition, <strong>and</strong> thus to provide<br />

a forum for networking <strong>and</strong><br />

alliance building. The workshop<br />

on Nutritional Anemia is an open<br />

event for those interested in gaining<br />

insight into the latest developments<br />

in this topic area.<br />

The proceedings of the workshop<br />

will be published early next year.<br />

We expect this publication to be<br />

highly authoritative <strong>and</strong> provide<br />

expert guidance on the prevention<br />

<strong>and</strong> treatment of Nutritional<br />

Anemia.<br />

The workshop <strong>and</strong> publication<br />

will be sponsored by SIGHT AND<br />

LIFE, Basel (www.sight<strong>and</strong>life.<br />

org). In focusing on Nutritional<br />

Anemia SIGHT AND LIFE is<br />

pursuing its new mission of addressing<br />

multiple micronutrient<br />

deficiencies (hidden hunger) related<br />

to important health issues<br />

in developing countries.<br />

SIGHT AND LIFE NEWSLETTER 2/2006<br />

Women in Burkina Faso during “good nutrition training”, see article on page 35.<br />

SIGHT AND LIFE is a humanitarian<br />

initiative of DSM Nutritional<br />

Products (for more information<br />

see the SIGHT AND LIFE website:<br />

www.sight<strong>and</strong>life.org). We are<br />

committed to the improvement of<br />

nutrition <strong>and</strong> health with emphasis<br />

on children <strong>and</strong> mothers in developing<br />

countries. It is the aim of<br />

SIGHT AND LIFE to combat ‘hidden<br />

hunger’, <strong>and</strong> to raise awareness<br />

of micronutrient deficiencies<br />

as public health issues.<br />

Low micronutrient intakes <strong>and</strong><br />

other forms of malnutrition are<br />

impairing the health of many<br />

people in numerous developing<br />

countries. The most vulnerable<br />

groups are children <strong>and</strong> mothers.<br />

Increased health risk with suscep-<br />

tibility to infections <strong>and</strong> increased<br />

child <strong>and</strong> maternal mortality are<br />

the consequences. Moreover, this<br />

impairs growth <strong>and</strong> development,<br />

cognition, vision <strong>and</strong> immune<br />

function, as well as school <strong>and</strong><br />

work performance.<br />

For its humanitarian work, SIGHT<br />

AND LIFE can draw on the<br />

expertise in nutrition, technology<br />

<strong>and</strong> analytics of DSM Nutritional<br />

Products. SIGHT AND<br />

LIFE supports many locally <strong>and</strong><br />

internationally active organizations.<br />

It has sponsored research,<br />

application projects, training of<br />

health professionals, <strong>and</strong> health<br />

<strong>and</strong> nutrition education in many<br />

countries in Africa, Asia <strong>and</strong> Latin<br />

America.<br />

Support is given in the form of<br />

vitamin A capsules, premixes<br />

containing micronutrients, grants,<br />

information <strong>and</strong> educational materials<br />

such as manuals, books,<br />

posters, reprints, etc. Furthermore,<br />

SIGHT AND LIFE gives<br />

technical assistance where required<br />

<strong>and</strong> promotes training <strong>and</strong><br />

education in order to increase<br />

local knowledge <strong>and</strong> expertise,<br />

<strong>and</strong> works towards sustainable<br />

improvement of nutrition.<br />

SIGHT AND LIFE publishes educational<br />

materials as well as the<br />

SIGHT AND LIFE <strong>Newsletter</strong> to<br />

increase knowledge on micronutrient<br />

nutrition <strong>and</strong> health, <strong>and</strong> to<br />

disseminate relevant information<br />

on programs <strong>and</strong> scientific news.<br />
