Traditionally, as in almost all cultures, the food of Africa uses a combination of locally available fruits, grains, and vegetables, milk and meat products. In some parts of Africa, the traditional African diet has a predominance of milk, curd, and whey. In much of tropical Africa however, cow's milk is rare and cannot be produced locally (owing to various diseases that affect livestock). Yet, differences, sometimes significant, are noticeable in the eating and drinking habits across the continent of Africa - African food differs in different parts of Africa, and East Africa, North Africa, West Africa, Southern Africa and Central Africa each have their own distinctive foods. They are very well known for their distinctive cooking styles.
