Every organ that secretes something needs large amounts of iodine to function normally. See a partial list to the right. Note that the thyroid
glands needs the most iodine, but the rest won’t work correctly without
iodine. Note that organs that secrete something are the same organs
that normally get cancer.

The Japanese that consume large amounts of seaweed (contains iodine) have the least cancer of anyone on the planet! Iodine seems to be protective
against cancer.

Iodine kills all single-celled organisms, and they cannot become resistant to it.

The parts of the body exposed to the outside world contain 30 times the amount of iodine as the blood. This effectively creates a shield of
iodine around the body, protecting it from infections. Of course this
shield cannot exist if you don’t consume enough iodine.

If micro-organisms get past your iodine shield, white blood cells create hydrogen peroxide and ozone to kill the “bugs” inside the white blood
cells. Thus iodine, hydrogen peroxide and ozone are critical components
of a normal immune system.

There are only micrograms of iodine in table salt. The body needs about 1000 times that much to function normally. The soils and foods in the US
are depleted of iodine. Unless you normally consume seaweed, you are
deficient in iodine and should be taking it as a supplement. You need
to take about 12.5 mg per day in tablet form. Do NOT take alcohol-based
iodine orally.
