Foods that are rich in Iodine
Iodine is an essential nutrient that is very beneficial to the body, more specifically to thyroid function. Iodine’s biggest role is to regulate the production of thyroxine (T4) and triiodothyronine (T3). These two thyroid hormones not only are essential for metabolic activity but also help keep your organs (brain, liver, heart, etc) functioning properly.
The National Institutes of Health recommends that an average adult takes in 150mcg (micrograms) of iodine. It is important to note that there is such thing though as taking in too much iodine. The side effects of an excess of iodine are very similar to being deficient so it is important to stay within the healthy daily amount.
Seafood: Cod and Shrimp (highest sources), Tuna, Haddock, White deep water fish, and all varieties of shellfish.
