Seaweed (kelp) is rich in vitamins, including B-12, and minerals, especially iodine. Iodine is a structural component of the hormones thyroxin and triiodothyronine. These hormones control metabolism throughout the body. Proper functioning of thyroid metabolism depends upon optimum dietary levels of iodine. Iodine deficiency, goiter, is a worldwide health problem. The World Health Organization estimates that over 800 million people are at risk. Seaweed (kelp) has been traditionally used to treat a variety of functional disorders, ranging from goiter to constipation. Recent scientific studies indicate that seaweed may also be an effective stimulator of the immune system, as well as a detoxifying agent. Seaweed’s polysaccharide content, e.g. fucans, seems to be partially responsible for some of these positive benefits.
