Floride and Thyroid

From: http://thyroid.about.com/cs/toxicchemicalsan/a/flouride_2.htm

Is fluoride in part the reason for near epidemic levels of hypothyroidism in the United States? Some experts and researchers believe this is the case. Fluoride had been used for decades as an effective anti-thyroid medication to treat hyperthyroidism and was frequently used at levels below the current "optimal" intake of 1 mg/day. This is due to the ability of fluoride to mimic the action of thyrotropin (TSH). It makes sense, then that out of the over 150 symptoms and associations of hypothyroidism, almost all are also symptoms of fluoride poisoning. Researcher and advocate Andreas Schuld has also found that excess of fluoride correlates with other thyroid-related issues such as iodine deficiency. Fluoride and iodine, both being members of the halogens group of atoms, have an antagonistic relationship. When there is excess of fluoride in the body it can interfere with the function of the thyroid gland. It is possible that iodine deficiency, which is the most common cause of brain damage and mental disability in the world, could be lessened by simply cutting back on the use of fluoride.
