Proportion of which of the following should be increased in diet to improve strength and growth of bones?

  1. Vitamin - D, Ca and vitamin- K
  2. Vitamin - D, Ca and iodine
  3. Vitamin - D, Ca and vitamin- A
  4. Vitamin - A, Ca and Zn
Correct Answer: Option(c)
Solution: Bone growth and strength require many components, most important of which are Vitamin D, calcium and vitamin A. The active form of vitamin D is called calcitriol which is very important for the formation of calcium-binding proteins. Without the calcium-binding protein calcium (most important mineral in the bones) in the food cannot be absorbed from the intestine. Vitamin A, in addition to helping in cell growth and differentiation, is crucial for bone growth.
