Maize or corn is a cereal crop that is grown widely throughout the world in a range of agroecological environments. The grains are rich in vitamins A, C and E, carbohydrates, and essential minerals, and contain 9% protein. They are also rich in dietary fiber and calories which are a good source of energy. (Staple food is the name for a food that can be stored easily, and eaten throughout the year.) It’s an important staple food for more than 1.2 billion people in Middle Africa.
