Your body needs nutrients like protein, carbohydrates, fat and many different vitamins and minerals such as vitamins C and A, iron and calcium from a variety of foods. Balancing food choices from the Food Guide Pyramid and checking out the Nutrition Facts Panel on food labels will help you get all these nutrients.
