Why is the use of iodised salt advisable?

Answer

• Thyroid gland produces thyroxine hormone . 
• Thyroxine is involved in metabolism of carbohydrates, proteins and fats and helps to balance the amounts required for optimum growth.
• Iodine is very important for the thyroid gland to be able to produce thyroxine.
• So when there is a deficiency or decrease in the amount of Iodine in our diet, we might suffer from goiter . 
• One of the symptoms of goite r is a swollen neck (thyroid gland is located near the neck). 
• Thus iodised salt is advisable.
