Fluoride from Tap Water Can Damage Your Thyroid Gland

safety-tested for thyroid or any other health risks.(B)

'Many Americans are exposed to fluoride in the ranges associatedwith thyroid effects, especially for people with iodinedeficiency,' says Kathleen Thiessen, PhD, co-author of thegovernment-sponsored NRC report. 'The recent decline in iodineintake in the U.S could contribute to increased toxicity offluoride for some individuals,' says Thiessen.

'A low level of thyroid hormone can increase the risk of cardiacdisease, high cholesterol, depression and, in pregnant woman,decreased intelligence of offspring,' said Thiessen.(C)

Common thyroid symptoms include fatigue, weight gain, constipation,fuzzy thinking, low blood pressure, fluid retention, depression,body pain, slow reflexes, and more. It's estimated that 59 millionAmericans have thyroid conditions.(D)

Robert Carton, PhD, an environmental scientist who worked for over30 years for the U.S. government including managing riskassessments on high priority toxic chemicals, says 'fluoride hasdetrimental effects on the thyroid gland of healthy males at 3.5 mga day. With iodine deficiency, the effect level drops to 0.7milligrams/day for an average male.'(E) (1.0 mg/L fluoride is inmost water supplies)

Among many others, the NRC Report cites human studies which show

- fluoride concentrations in thyroids exceeding that found in othersoft tissues except kidney

- an association between endemic goiter and fluoride exposure orenamel fluorosis in human populations

- fluoride adversely affects thyroid and parathyroid hormones,which affect bone health

'If you have a thyroid problem, avoiding fluoride may be a goodpreventive health measure for you,' writes Drs' Richard and KarileeShames in 'Thyroid Power.'(F).

Scientific American quotes John Doull, professor emeritus ofpharmacology and toxicology at the University of Kansas MedicalCenter, who chaired the NRC committee thusly, 'The thyroid changesdo worry me.'

Over, 1800 Physicians, Dentists, Scientists, Academics andEnvironmentalists urge Congress to stop water fluoridation untilCongressional hearings are conducted. They cite new scientificevidence that fluoridation is ineffective and has serious healthrisks. (http://www.fluorideaction.org/statement.august.2007.html)

'Fluoride can harm bones, teeth, kidneys, the brain and more,' sayslawyer Paul Beeber, President, New York State Coalition Opposed toFluoridation. "It's time to stop fluoridation."
