Classification of food nutrients

Food nutrients are chemical substances that are found in the foods. Nutrients are used for the performance of body functions and those that are required in large quantities by the body are called macro nutrients while those that are required by the body in a very little quantity are called micro nutrients. Each nutrient performs a specific function in the body and the lack or shortage of any in our diet results in deficiency diseases.

Food nutrients include the following:

  1. Carbohydrates
  2. Protein
  3. Fats and oil
  4. Vitamins
  5. Minerals
  6. Water

Carbohydrate

Carbohydrates are organic compounds whose molecules contain carbon, hydrogen and oxygen atoms. Hydrogen and oxygen atoms are always in the ratio 2:1 as in water. Carbohydrates serve a significant function in nature because they are the chief source of immediate energy for animals (including man).

Classification of carbohydrates

Carbohydrates are classified into three: namely

  1. Monosaccharide
  2. Oligosaccharides
