Fats

Fats in Food:

  • Fats are made up of carbon, hydrogen and oxygen. Butter, ghee, milk, egg-yolk, nuts and cooking oils are the major sources of fat in our food.
  • An adult needs about 35 g fat every day. Our body stores the excess energy in the form of fat.
  • This stored fat is used by the body for producing energy as and when required so fat is considered as energy bank in our body.
  • Fats are essential for the absorption of vitamins A, D, E and K in the body.
  • Fat in our body also prevents heat loss from the body surface.
  • Atherosclerosis, sometimes called "hardening of the arteries," occurs when fat, cholesterol, and other substances build up in the walls of arteries. These deposits are called plaques. Over time, these plaques can narrow or completely block the arteries and cause problems throughout the body.
