Iodine benefits

Iodine is a component of the thyroid hormones thyroxine and triiodothyronine, which help regulate cell activities. These hormones are also essential for protein synthesis, tissue growth (including the formation of healthy nerves and bones), and reproduction.
The best natural sources of iodine are seafood and plants grown near the ocean, but modern Americans are most likely to get the iodine they need from iodized salt (plain table salt with iodine added). And here’s an odd nutritional note: You may get substantial amounts of iodine from milk. Are the cows consuming iodized salt? No. The milk is processed and stored in machines and vessels kept clean and sanitary with iodates and iodophors, iodine-based disinfectants. Tiny trace amounts get into the products sent to the stores. Iodates are also used as dough conditioners (additives that make dough more pliable), so you’re also likely to find some iodine in most bread sold in supermarkets.
