Overview:Kelp is a large, leafy brown edible seaweed rich in vitamins and minerals that grows along colder coastlines. Kelp is an excellent source of iodine, a major component of thyroxine and triiodothyronine, thyroid hormones that affect weight gain, and cellular metabolic rates. One to two milligrams of iodine per week are required to prevent goiter. Based on epidemiological studies, thyroid disease is practically unknown in people who regularly eat kelp. The alginates in kelp (complex polysaccharides), like other soluble fibers, have a soothing and cleansing effect on the digestive tract and are known to help prevent the absorption of heavy metals, waste products, and other toxic substances.
Traditional Use/Benefits/Body Systems:As a nutritious addition to soups, stews, and breads and as a savory garnish to rice and vegetable dishes. As a good source of iodine.
