What will happen if the intake of iodine in our diet is low?
Iodine is essential for the synthesis of hormone thyroxin. The thyroid gland secretes a hormone thyroxin which controls the rate of metabolism of carbohydrates, fats and proteins in the body. If there is a deficiency of iodine then there will be a deficiency of thyroxine hormone in the body and will cause goitre. The neck appears to be swollen due to enlargement of the thyroid gland which is also called a goitre.
