We are advised to take iodised salt in our diet by doctors. Justify it's importance in our body.

 

Answer:

-lock-

Iodine salt is recommended in our diet because it plays an important role in maintaining thyroid function and overall health of an individual:

  1. Iodine is essential for the synthesis of thyroxin hormone in the thyroid gland.
  2. Thyroxin regulates carbohydrate, fat and protein metabolism in our body and provides the best balance for growth.
  3. The deficiency of this hormone can lead to a disease called Goitre, where there is enlargement of the thyroid gland.
