Carbohydrates include starches and sugar and give us energy are found in breat, potatoes and rice.


Vitamins and minerals in vegetables and fruit help us o grow and keep our body healthy because they protect us from many illnesses.


Fats give us energy. There are two types of fat: animals fats in eggs, butter, fish and meat, and vegetables fats in olives and nuts.
