Iodine is a trace element that is naturally present in some foods which is added to some types of salt, and is available as a dietary supplement. Iodine is the key component for the thyroid hormones thyroxine (T4) and triiodothyronine (T3). These hormones control the body's metabolism and many other important functions. The body also needs thyroid hormones for proper bone and brain development during pregnancy and infants. Foods like Seaweed, Fish, shellfish, Table salts labeled “iodized” Dairy (milk, cheese, yogurt) Eggs. Chicken etc. are rich in iodine. Similarly, Iodine deficiency leads to Cretinism, Goiter, Hashimoto's Thyroiditis, Congenital Hypothyroidism, Postpartum Thyroiditis.
