The role of enriched foods in infant and child nutrition

Abstract

Since the last century, fortified and enriched foods are products whose original composition has been modified -through addition of essential nutrients -to satisfy specific population needs. For the fortification of foods to have a positive impact on nutritional status, the micronutrients added must be well absorbed and utilized by the organism (bioavailability). Diverse factors affect bioavailability, such as the nutritional status of individuals, the presence in the diet of substances which facilitate or inhibit its absorption, interactions among micronutrients, illnesses, and chemical characteristics of the compound used for fortification. In countries such as Chile, Venezuela and Mexico, important effects have been demonstrated in reducing iron deficiency anaemia in children under 5 years of age. In less than a decade, the salt iodization programme has also proven its effectiveness. Other programmes have fortified foods with Zn, vitamin A and folic acid, which are deficient in infants and children of many populations. In summary, food fortification is a low-cost, relatively simple strategy that may reach a wide range of people, and contribute to reducing the high prevalence of micronutrient deficiencies affecting children, especially in poor countries. The costs due to losses of human capital and their repercussions on health and future development are very high. Building links among academic researchers, politicians, food manufacturers and consumers is essential in order for food fortification to be efficacious and effective, and therefore should be considered as part of an integral strategy to combat micronutrient deficiencies.

Are Vitamin A and Iron Deficiencies Re-Emerging in Urban Latin America? A Survey of Schoolchildren in Bogota, Colombia

“…Iron fortification of commonly eaten foodstuffs has been successfully implemented in several Latin American countries, including Venezuela, Chile, and Mexico, to decrease the burden of iron deficiency and anemia in vulnerable populations [34]. In 1996, a mandate was put into place in Colombia to fortify wheat flour with a minimum of 44 mg of iron per kilogram in addition to vitamin B 1 , vitamin B 2 , niacin, and folate [35].…”

Evaluation of Retinol Level Among Preschool Children, Pregnant and Lactating Women Attending Primary Health Care Centres in Baghdad

“…Vitamin A can be obtained from food, either as preformed vitamin A in animal products, such as eggs and dairy products, or as provitamin A carotenoids, mainly b-carotene in plant products, such as green leafy and yellow-colored vegetables and orangecolored fruit, Vitamin A deficiency is essentially attributed to inadequate dietary intake [13].…”
