Importance of Food Fortification and in-Home “Fortification” to
Complement the Nutrient Adequacy of the Diet

Anthropometric indicators in pre-school age children < 2 S.D.
Why do not consider other reasons beyond protein-energy undernutrition?
Abt Associates | pg 4 OD-2013-01
What about breast-feeding practices, use of snacks, or stimulus?

Causes of stunting and anemia
Type of growth and development
Physical Factors: good
nutrition, good health, disease resistance
Social Factors (Care) : Early stimulation, belonging to a family, attention, love
Genetic, Demographic & Environmental Factors:
Race, gender, ethnicity, altitude, sun-exposure,
intestinal flora
“Food Security” (Foods)
Child/mother health practices,
Immunization (Health)
Safe water and hygienic foods,
healthy environments (Hygiene)
Macronutrients supply: cereals,
pulses, oil and fats, animal protein
Some vitamins and minerals: milk, eggs,
fruits, vegetables, fortified foods
Avoidance of toxins and anti-nutritional
factors: mycotoxins, e.g.
Well absorbed Fe/Zn (fermentation, meat,
fish, fortification, supplementation)
Wasting, underweight and overweight
Essential fatty acids supply, mainly n-3
(fatty fish, and certain vegetable oils)
Non-digestible oligosaccharides
and fiber: healthy intestine status.
Abt Associates | pg 6 OD-2013-01
Stunting is only an indicator; the
important is to correct its causes.

Complementary feeding
Nearly half of the “1000 days” depends on the mother nutritional status.
Exclusive lactation
Pregnancy
Abt Associates | pg 7 OD-2013-01
Nutritional value of breast milk depends
mostly on the mother’s diet

Vit. B-6¶ 80 % Vit. D¶ ? ***
Vit. B-12¶ 16 %** Iodine 6-23 %
Vit. C 50 % Selenium 52 %
Type II Nutrients (independent)

Folate Iron
(Niacin)**** Zinc¶
Calcium Copper
Notes: * Estimated proportion of the Adequate Intake (AI) for the child of an under-nourished mother. ** Not possible to increase during the lactation period; it requires good status pre-pregnancy. *** Depends on sun exposure. **** It could be synthetized from the amino-acid tryptophan ¶ Deficiency associated to stunting.

Questions: 1. Why to extend supplementation with iron from 6-24 months of age to 59 months of age? 2. Why to supply additional folic acid to children younger than 36 months of age?
