carbohydrates: these provide a source of energy. proteins: these provide a source of materials for growth and repair. fats: these provide a source of energy and contain fat soluble vitamins. vitamins: these are required in very small quantities to keep you healthy. mineral salts: these are required for healthy teeth, bones, muscles etc.. fibre: this is required to help your intestines function correctly; it is not digested.
