In order to stay healthy it is important to have a balanced diet. We should eat three main groups of food. These groups are protein, carbohydrate, and fat. Proteins are very important for building our body. They help us to build new cells as old ones die. Meat and milk products are major sources of protein. We can also get protein from fish, eggs and beans. Carbohydrate and fat are important as they enable us to store energy. Carbohydrates are found in sugar and in cereals.
