What Good Are Fats?

Fatty molecules are composed of glycerol and a fatty acid. They can be liquid (oil) or solid at room temperature. Some fats are actually good for you, such as omega-3 fatty acids.

Fats are needed by your body, so it is not wise to be very skinny, especially for a woman.

Uses of fat:

  • Vitamins A, D, E and K are stored in fat. Vitamin A deficiency may lead to blindness. Vitamin D deficiency may lead to osteomalacia (soft bones), osteoporosis, or rickets. Vitamin E deficiency may lead to body wasting diseases such as cystic fibrosis, pancreatitis, and cholestasis (bile-flow obstruction). Vitamin K deficiency may lead to bleeding disorders, fractures, and osteoporosis.
  • When muscle glycogen is depleted, fats often serve as energy. they are broken down into glycerol and fatty acids. The glycerol is converted to glucose.
  • Fats protect organs from damage.
  • Fats promote healthy skin and hair.
  • Fat protects nerves by making up the largest part of the myelin sheath.
  • Fat is used often to store foreign molecules that may be harmful to the body until they are metabolized excretion, accidental or intentional bloodletting, sweat, or hair growth.
