Nutrition is the study of how the body uses food and its nutrients to maintain health. There are 6 classes of nutrients: carbohydrates, proteins, fats, vitamins, minerals, and water. Carbohydrates, proteins and fats provide energy, vitamins and minerals regulate body functions, and water transports nutrients and wastes throughout the body. Common energy providers, regulators, and their sources are also outlined.
