Fluoride Damages the Thyroid, Report Shows
New York - September 24, 2007 - 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.(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 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, 900 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.
