Other nutritional problems
Apart from stunting and under weight –
1. Anaemia - 60-90%
2. Iodine Deficiency - endemic most parts of the country
3. Goitre - endemic in North East, sub Himalayan
range, many tribal belts in central India
4. Fluorosis - endemic many parts of the country
-21 –
According to Recommended Dietary Guidelines
60-65% Calories from Carbohydrates
25-30% from Fat
10-12% from Protein
Each of these calories, proteins and fats must be derived from as
many foods as possible
In the rural area of India 80% of Calories are derived from from
Cereals
Those with adequate calories from cereals have high iron intakes,
but because almost All the calories come from cereals, the iron is
not available…this population must derive its calories from other
sources such as pulse, meat, vegetable, milk egg to use this iron.
- 22 • Children Only 30% have calorie adequacy (from cereals).
They are deficient in all the other nutrient rich foods
recommended for children.
• The WHO Recommendation
• Calories - 30-40% must come from fats (low volumes and
energy densities)
•
Vitamin A, calcium, iron - from milk, eggs, flesh foods,
vegetables, fruit etc. (will also contribute additional calories),
• Cereals, pulse to be used to bridge the calorie gap.
•
In India – it is reversed, cereal load has resulted in simple
minded diagnosis of micronutrient deficiencies.

Phytonutrients act synergistically with micronutrients – as part of an
orchestra.
Example - -carotene, vitamin C, vitamin E and selenium act as
Antioxidants with flavonoids, carotenoids and phenolic compounds.

An orchestra cannot be converted to a solo.

-carotene supplementation to prevent lung cancer did not lower
rates of lung cancer – it increased it among high risk groups.

Single agents can be counter productive.

- 35 Supplying additional iron would reduce anemia only if
iron is very deficient and only up to the point where
another factor becomes rate limiting. In the case of
poor societies, other factors- both nutritional and
environmental-
are
as
important.
Therefore,
management of nutritional anemia requires Health
and food (providing many nutrients, not just iron).
Instead of putting all nutrients into one food (cereal)
Cereal should be eaten with nutrient rich foods.
- 36 Further addition of iron in these diets or iron supplements may
cause iron overload known to have the following impacts on
1. Oxidative damage, diarrhea, in undernourished populations
2. Infections, like Malaria, TB, HIV,
3. Even deaths
What is required is sources of foods which make the iron available
such as
1. Vitamin C rich foods
2. Small amounts of meat which provides haem iron
3. Fill the calorie gap with foods other than cereals
These increase the iron availability by 10 times.
-37 Wheat flour fortification
To increase intakes of iron – using whole wheat flour (cereal) - iron
availability is only – 1-2%
Other option - chemical addition to whole wheat flour
NaEDTA – to increase iron availability by 2-3 times
However, it increases viscosity of the flour
? Toxicity – and binding with other metal ions
Costly – four times
Ferrous sulfate - without EDTA low bioavailability
alters taste – with EDTA – iron amount have to be
decreased net iron intake the same
Elemental iron – Low bioavailability
Fortification of flour in the West is carried out using MAIDA
(refined flour)
- 38 Options – whole country to switch to Refined flour (MAIDA) or
Tolerate Toxicity of EDTA
Safe levels to be calculated in undernourished populations
Intake should not be more than 2.5 mg / kg body weight
At this level of EDTA it does not provide adequate iron for children
No studies on the use of fortified flour in children
- 39 St.John’s study (Kurpad)
Role of school lunch programme on anemia status of school
children
Government school children – given the usual vitamin A and antihelmenthic
Had the regular school lunch programme (cooked rice, dal, some
vegetables)
No iron tablets were distributed
Anemia reduced from 60% to 20%
Important role of providing food on Anemia
- 40 Millions of tons of cereals will be processed so that a
few mg quantities of a nutrient is added– and only
1-5% is available to humans
Need to re-look at strategy
Studies done in the following countries did not show
improvements in haemoglobin after the distribution
of iron fortified wheat flour.
Srilanka
Bangladesh
Thailand
Morocco
Ivory coast
India
- 41 –
The National Anemia Prophylaxis Programme
Iron tablets – distributed under medical supervision.
Health care may be accessed (differences between
Pemba and Nepal study)
Iron Fortified Wheat Flour – may leave Governments and
people complacent.
Research on the relative safety of iron supplements as
tablets or elixirs and fortified foods in areas endemic for
malaria and other intracellular infections are not known.

locally.
2. Half the children of this country will require this
3. Assured supply for years is hard to imagine
4. Local populations will learn to trust only packaged
food
5. Women will forget how to feed their children
