Seaweed? Yep, that's right, those beautiful vegetables that grow in the ocean. They're really quite tasty! I realized recently that I had not yet highlighted this wonderful, mineral-rich plant. Did you know that sea vegetables offer a concentrated source of trace minerals, particularly iodine? Iodine is needed to make thyroid hormone. Thyroid hormone is incredibly important for normal function of the human body. So important that every single cell has a receptor for this amazing "master switch" of metabolism. Want to have perfectly regulated body weight and body temperature? Then shoot for optimal thyroid hormone function. How do you do that? Eat a diet that keeps your autoimmune thyroid antibodies down, and add in some seaweed on a regular basis.
Seaweed is one of nature's richest sources of iodine. Iodine is THE key ingredient in thyroid hormones. We have all heard of T4, tetraiodothyronine, the pre-hormone, and T3, triiodothyronine, the active form of thyroid hormone, but what does that mean? It means four iodines attached to a tyrosine amino acid or three iodines attached to a tyrosine amino acid. One of these iodines is removed with the help of selenium as a cofactor when turning the inactive T4 into the active T3 thyroid hormone. So in essence, if you do not have adequate iodine and selenium, your body may not be able to produce enough thyroid hormone. Are you eating a diet high in phytates or oxalates? You may have an increased need for iodine as these foods tend to bind to iodine.
Seaweed can be found at your local health food store. Look for kombu (kelp), wakame, hijiki, arame, or dulse. I keep kelp granules in a small container on our table to sprinkle on food. I like to add wakame to soups like this one.
