Understanding undernutrition

1 Nutrient-rich foods must be available to the family. Sufficient nutrient-rich foods must be available where the family can buy them, and must be affordable. 2 Children must consume enough nutrient-rich foods. Children must be given enough nutrient-rich food to eat. Food must be prepared in such a way that the nutrients are preserved and easily absorbed. For most foods, this means not overcooking them. For good vitamin A absorption, there must also be enough fat in the diet. 3 Children must be free from disease and infection. Measles, intestinal worms, diarrhoea and other infections all reduce the absorption – and increase the loss – of many micronutrients, including vitamin A.
