Iodine Phobia & Salt Truth
Iodine deficiency is thought to be the most common cause of hypothyroidism and the one true cause of goiters. Once researchers realized this many decades ago, health authorities around the world began adding iodine to table salt. But interestingly allopathic medical science is now saying that in countries where iodine has been added to highly processed table salt, the rates of autoimmune thyroid disease have risen.
Though there are several studies  from around the world that support this conclusion, one of the principle studies was published in the European Journal of Endocrinology asserting this without any attention to or control of the toxicity of the salt itself, selenium status of the studies participants, or the danger that water fluoridation potentiates for the thyroid. These factors and others are involved in thyroid and autoimmune diseases; mercury is an especially dangerous thyroid poison in this regard. So is bromide and they are putting more than ever in bread.
Iodine deficiency we get is partly a result of toxicity from Fluoride
and Bromine. Bread has ten times more Bromine in it than it used to
and the sources of Fluorine are nearly ubiquitous today. So who does not
need Iodine? I find that nearly everyone needs more than they are getting.

Contamination from chemicals and heavy metals has cumulative effects such as weakening the immune system. When heavy metals are found on the receptor sites of the thyroid they literally invite the immune system to strike out against thyroid cells. The immune system produces thyroid antibodies in seek-out-and-destroy missions against these foreign substances. Depending on the specific subtype, thyroid antibodies can destroy thyroid cells, cause thyroid inflammation, or cause thyroid cells to produce excess thyroid hormone.
Selenium is necessary for the conversion of T4 to T3. (Incomplete conversion results in high levels of reverse T3, an inactive hormone.) Selenium has also been shown to reduce autoimmunity against the
thyroid (i.e. to treat the underlying cause of Hashimotos thyroid disease.)
When we add the total ignoring of magnesium deficiency as yet another uncontrolled factor we quickly realize how careful we need to be about interpreting scientific medical conclusions. Add the fact that the thyroid is affected by widespread mercury contamination and we can see how distorted medical studies can become in their lust to study one factor at a time while remaining blind to other crucial issues.
Studies have documented that mercury causes hypothyroidism, damage of thyroid RNA, autoimmune thyroiditis,,, and impairment of conversion of thyroid T4 hormone to the active T3 form. These studies along with clinical experience indicate that exposure to mercury and/or toxic metals appears to be the most common cause of hypothyroidism and the majority of patients treated with metal detoxification recover or significantly improve.
Manmade sources of mercury: dental amalgams, thimerosal in vaccines, mining of silver, coal-fired electrical plants, municipal incinerators, crematoriums, curing of plastics, fireworks (pharoahs serpents and bengal green lights), anatomical specimen preservatives, fungicides and pesticides (golf courses), laboratory tests in slide preparations and reagents, certain drugs, thermometers, fluorescent lights, certain button-sized batteries.
As far back as the early 1920s, Goldemberg showed that fluoride was displacing iodine, rendering the community hypothyroid from iodine deficiency. The thyroid-stimulating hormone output from the pituitary gland is inhibited by fluoride, thus reducing output of thyroid hormones. Fluoride competes for the receptor sites on the thyroid gland and so do mercury and bromide. This contamination might also invite an autoimmune response.
Byron Richards writes, Adequate iodine is also needed to block various compounds from binding to and accumulating in the thyroid gland (fluoride, perchlorate, goitrogens in food). Problems with chemicals affecting the thyroid gland have been known about for decades. A recent Russian study showed that general environmental pollution (of which the U.S. has plenty in every metropolitan area) significantly aggravates iodine lack (meaning pollution displaces iodine in the human body).
European doctors used fluoride as a thyroid-suppressing medication for patients with HYPER-thyroidism (over-active thyroid). Fluoride was utilized because it was found to be effective at reducing the activity of the thyroid glandeven at doses as low as 2 mg/day.
