There are six major nutrient groups: carbohydrates, fats, proteins, vitamins, minerals, and water. Nutrients can produce energy for the body, build or repair the body or regulate the body. Carbohydrates and fats are energy producers. Proteins perform all the functions. Minerals and water are builders, repairers and regulators. Vitamins are in the regulatory category.
