Iodine is an essential macromineral. Almost half the iodine is found in the
             thyroid gland which is located in the throat. Iodine is an important component of
             thyroid hormones, which control energy, metabolism in the body as well as the
             body's temperature, reproduction, and growth. It is not found in the body so it is
             very important that you get about .15 mg. daily. Some foods such as vegetables,
             grains, table salt, dairy products, and especially seafood are the best sources of
             iodine. Breathing in sea air everyday will give you a sufficient amount of iodine
             to prevent a disease called goiter. There are two types of goiter: toxic and
             simple. Toxic goiter is caused by excess of thyroxin secretion. Symptoms may
             include rapid heart beat, tremor, increased sweating, increased appetite, weight
             loss, weakness, and fatigue. Other symptoms may include eye problems such as
             staring or protrusion. Goiter affects over 200 million people throughout the
             world. 96% is caused by iodine deficiency. Goiters are rare in the U.S. and other
             industrialized countries because iodine is now added to table salt.
             Iodine affects body functions too. Hair and nail growth are affected by
             iodine. The brain, skin, speech, teeth, energy production, metabolism, and
             physical & mental health development are dependent on a well-functioning
             thyroid gland. Deficiency symptoms include dry hair, goiter, intellectual
             disability, paused growth, irritability, nervousness, and obesity. If a pregnant
             woman takes iodine during pregnancy, the development of goiter will be
             decreased for both the mother and the child. Iodine is the most efficient
             treatment for children who have goiter.
             Iodine does have a down side to it, too. It is not toxic up to 2,000 mcg
             daily, but it may cause acne. Too much iodine is can link to thyroid cancer.
             Some people are sensitive to iodine and may break out in a rash if their iodi...
