Iodine-Rich Foods

A diet centered on soy, corn, millet, grains, cassava, fruits, and vegetables with no animal products, eggs, or cheese carries a very high risk of iodine deficiency. Seaweed and kelp are among the most concentrated dietary sources of iodine. Shellfish are the highest dietary source of iodine and are especially recommended during pregnancy. Vegetables and fruits are not reliable dietary sources of iodine. Organ meats are a moderate but often overlooked dietary source of iodine.
