Iodine enters the body through iodine-rich foods, including certain salts (âiodized saltâ), eggs, sea vegetables and fish. We rely on iodine to create thyroxine (T4 hormone) and triiodothyronine (T3), two of the main hormones produced by the thyroid that control numerous important functions.
Iodine is an essential trace element; the thyroid hormones thyroxine and triiodothyronine contain iodine. In areas where there is little iodine in the dietâtypically remote inland areas where no marine foods are eaten, iodine deficiency is common.t is also common in mountainous regions of the world where food is grown in iodine-poor soil. Prevention includes adding small amounts of iodine to table salt â a product known as iodized salt. Iodine compounds have also been added to other foodstuffs, such as flour, water and milk in areas of deficiency.
