Minerals - Iodine - Source

Iodine-rich foods include commercially iodized salt, blackstrap molasses, onions, seafood, saltwater fish, and Kelp. Iodine is also found in Dulse, mushrooms, lima beans, sea salt, asparagus, soy beans, sesame seeds, garlic, and spinach.

Certain foods, when eaten raw in large amounts, can block the absorption of iodine into the thyroid gland. These include cabbage, cauliflower, kale, peaches, pears, spinach and turnips.
