biology food for health fats fats and their test different nutrients in food

  1. Fats yield double amount of energy yielded by glucose on oxidative breakdown

  2. Fats can be stored in an almost pure unhydrated form

  3. Fats accomodate in lesser space

  4. All the above

Show answer
Correct Option: A
Explanation:

Fat is an essential part of our diet and is important for good health.

fat is the major storage form of energy in the body. These are found in plant foods and fish. Fats help in the absorption of fat-soluble vitamins A, D, E, and K. 

So, the correct option is ‘Fats yield the double amount of energy yielded by glucose on oxidative breakdown’.
