Energy is needed for normal body functions including maintaining body temperature, breathing, digestion, thinking, exercising, and managing the heart rate. That energy comes from protein, fat, and carbohydrates. Carbohydrates are broken down into glucose which the body uses as its primary and most efficient source of energy. Carbohydrates are the only energy source the brain, nerves, and developing red cells can use for energy. Protein and fat are used as sources of energy only when carbohydrates are depleted.
Complex carbohydrates include potatoes, oats, corn, peas, whole wheat pasta, beans, and brown rice and are excellent sources of energy. They are also a good source of protein, vitamins, and minerals. Complex carbohydrates contain fiber which will slow down the release of glucose.
