Facts about Fats

Nutrients are the components present in the food that are required for normal functioning, growth and development of our body cells, tissues and organs. These compounds present in food provide us with energy that facilitates repair and growth and helps to carry out different life processes.

In general, nutrients are of two types: macronutrients and micronutrients.

  1. Carbohydrates, fats and proteins are grouped into macronutrients, as these food components are required in larger amounts and function by providing energy for the proper functioning of the cells, tissues and other organ systems in our body.
  2. Minerals and vitamins are grouped into micronutrients, as these components are involved in building and repairing damaged tissues in order to control the body process. These nutrients are required by the body in small amounts.
