This booklet lists the major nutrients, discusses the role each plays in the body, and lists some of the foods that each nutrient can be found in. An explanation of the relationship between nutrients and energy, how the body gets the nutrients it needs from the diet, and the nutrients needed from before birth until the later years is included. A food guide lists the four basic categories with the daily requirements of each. Nutritional labeling and the value of processed foods are also discussed. (PD)
