Maize has become the staple food for more than 1 billion people in sub-Saharan Africa and Latin America. Maize is high in carbohydrates but lacks essential micronutrients such as vitamin A.

Vitamin A is an essential nutrient lacking in the diets of poor malnourished population. Vitamin A deficiency retards growth, increases risk of disease, and can cause reproductive disorders.

Maize exhibits tremendous genetic diversity, and there are many types with high levels of provitamin A, a compound converted into vitamin A when the maize is eaten. These have been used to conventionally breed new varieties of maize that are an important dietary source of vitamin A maize.
