Carbohydrates are the main energy source of human diet. They efficiently convert into glucose, which is the major fuel for all body cells and the only source of energy for the brain and red blood cells. There are two types of carbohydrates in food. They are simple carbohydrates found in fruits, milk, while refined carbohydrates are found in sugar and all products where sugar is added (cakes, biscuits, chocolate and some beverages). Complex carbohydrates are found in vegetables, whole grains, beans, potato, bread, pasta and rice. When you choose carbohydrate food, always choose unprocessed foods, such as fruits, vegetables, beans, peas and whole grain products. Such diet gives energy and makes you feel full for a longer period.
