Fluoride Damages the Thyroid, report shows

 

First-ever government review

of fluoride/thyroid toxicology shows risk .2008-05-19

15:54:10 - There is clear evidence that small amounts of fluoride, at

or near levels added to U.S. water supplies,

present potential risks to the thyroid gland, according to the National

Research Council's (NRC) first-ever published review of the

fluoride/thyroid literature.(A)

Fluoride, in the form of silicofluorides, injected into 2/3 of U.S.

public water supplies, ostensibly to reduce tooth decay, was never

safety-tested.(B)

" Many Americans are exposed to fluoride in the ranges associated

with thyroid effects, especially for people with iodine deficiency, "

says Kathleen Thiessen, PhD, co-author of the government-sponsored NRC

report. " The recent decline in iodine intake in the U.S could

contribute to increased toxicity of fluoride for some individuals, "

says Thiessen.

A low level of thyroid hormone can increase the risk of cardiac disease,

high cholesterol,

 

depression and, in pregnant woman,

decreased intelligence of offspring, " said Thiessen.©

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 million

Americans have thyroid conditions.(D)

Robert Carton, PhD, an environmental scientist who worked for over 30

years for the U.S. government including managing risk assessments on high

priority toxic chemicals, says " fluoride has detrimental effects on

the thyroid gland of healthy males at 3.5 mg a day. With iodine

deficiency, the effect level drops to 0.7 milligrams/day for an average

male. " (E) (1.0 mg/L fluoride is in most water supplies)

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

- fluoride concentrations in thyroids exceeding that found in other soft

tissues except kidney

- an association between endemic goiter and fluoride exposure or enamel

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 good preventive health measure for you, " writes Drs' Richard and

Karilee Shames in " Thyroid Power. " (F).

Over, 1,700 Physicians, Dentists, Scientists, Academics and

Environmentalists urge Congress to stop water fluoridation until

Congressional hearings are conducted. They cite new scientific evidence

that fluoridation is ineffective and has serious health risks.
