Iodine is an important trace mineral, which is required in sufficient quantities for the proper mental and physical growth of the body. Iodine is required in small amounts for the synthesis of thyroid hormone, like triiodothyronine (T3) and thyroxine (T4). It is also required for strengthening the immune system. Most of the iodine content in the body is situated in the thyroid gland and the rest of it gets dispersed to other locations in the body, such as, blood, salivary glands, mammary glands, etc.
Traces of iodine can be found in soil and salt. However, until the twentieth century, not much was known about iodine rich salt and therefore there were many cases of hypothyroidism in the United States and Canada. But now, with the use of iodine rich salt, the scenario has changed completely and now very rarely, you would find any such iodine deficiency case. Speaking of iodine deficiency, it is caused due to lack of intake of iodine, through diet. Although, the use of iodine rich salt has completely eradicated it from the developed countries, people from many underdeveloped nations are still deprived of iodine rich salt or iodine rich foods in their diets. Iodine deficiency symptoms include, hypothyroidism, goiter, retarded mental and physical growth etc. Therefore to avoid all these symptoms, it is necessary that along with iodine rich vegetables and fruits, one also includes other foods rich in iodine in his/her diet!
But, what are the foods rich in iodine? To answer in short, some of the best sources of iodine, other than iodine rich salt are, sea food, eggs, cow milk, breads and cereals etc. But, the table below would respond to your query in a better way.
