Six Nutrients and A Balanced Diet
A balanced diet
Definition
A balanced diet supplies the body with appropriate amounts of the major nutrient groups needed for energy, growth, repair and healthy body functions.
Formula / Key Relation
Different nutrients have different roles. Carbohydrates → major energy source. Proteins → growth and repair. Lipids → concentrated energy store and part of cell membranes. Vitamins → required in small amounts for normal body processes. Minerals → inorganic nutrients needed for functions such as bone formation and oxygen transport. Water → solvent, transport medium and temperature regulation. Balanced diet: `appropriate energy + essential nutrients + sufficient water` Six nutrient groups: `carbohydrates + proteins + lipids + vitamins + minerals + water`
