Fats-
Fat is also an essential ingredient of food. Fat is also a compound. It is made up of carbon, hydrogen and oxygen. Fat provides heat and energy to the body. It also helps in 'regulation of body temperature'. It is helpful in making the body soft and oily and protects the body from external effect of hot and cold climates. Its accurate quantity makes the body beautiful. For the purpose of energy, fat is considered better than carbohydrate. If fat is used with carbohydrates in food, fat can be digested easily as well as rapidly. If excess fat is not used by the body, it is accumulated in the body by which various organs of the body do not work efficiently. If fat is available in less quantity in the food, carbohydrate changes into fat up to some extent.
