A nutrient is either a chemical element or compound used in an organism's metabolism or physiology. A nutrient is essential to an organism if it cannot be produced by the organism and must be obtained from a food source.[1]

This article deals with nutrition in animals, especially humans. Nutrition in plants, fungi, bacteria and archaea is not discussed here.

Substances that provide energy

  • Carbohydrates are compounds made of sugars. Carbohydrates are named by the number of sugar units they have.
Monosaccharides (such as glucose and fructose) have one.
Disaccharides (such as sucrose and lactose) have two.
Oligosaccharides, and polysaccharides (such as starch, glycogen, and cellulose) have more.
  • Fats are a glycerin molecule with three fatty acids attached. Fats are needed to keep cell membranes functioning properly, to insulate body organs against shock, to keep body temperature stable, and to maintain healthy skin and hair. The body does not manufacture certain fatty acids and the diet must supply these.
