Iodine is an essential mineral, and most of the American population does not consume enough of this nutrient. In the United States most medical doctors believe that people get enough iodine from iodized table salt, but this is not true. It has been found that 1 in 10 Americans does not get the proper amount of iodine. Iodine is responsible for many roles in the body. It is needed for proper thyroid function –the thyroid gland regulates most of the endocrine system-- cellular metabolism, healthy hormone production, cancer prevention and immune response. It is also required to maintain a healthy immune system, and it is known for its other benefits such as its anti-cancer, antibacterial, anti-viral and anti-parasitic properties.
