All those substances which are necessary for the operation and performance of various biological activities towards the organisms are called nutrition. There are 4 types of nutritional substances.

There are 4 types of nutritional substances
  • Energy production
  • Metabolic Controller
  • Growth and building materials
  • Genetic material
1. Energy production
Nutrients that generate energy, energy producing substances like fats, carbohydrates.
2. Metabolic Controller
Nutrients that control various metabolic functions of the body.
3. Growth and building materials
Nutrients, which correct and growth and wear and tear of the body (proteins).
4. Genetic material
Nutrients that help to carry genetic properties from one generation (nucleic acid). It is very important for the physical development of mankind, functioning, immunity of the body, to heal the broken body and all the organisms like.
  • Carbohydrate
  • Protein
  • Fat
  • Vitamins
  • Water
  • Nucleic acid
  • Mineral salts

  4. Gene (genetic) creates the development of symptoms.
  5. It acts as convection.

3. Fat
