Answer 2

Iodine is a chemical element. The body needs iodine but cannot make it. The iodine needed by the body must come from the diet. As a rule, there is very little iodine in food, unless it has been added during processing. Processed food typically contains more iodine due to the addition of iodized salt. Most of the world's iodine is found in the ocean, where it is concentrated by sea life, especially seaweed.
