"Some recent studies suggest that over-consumption
of fluoride can raise the risks of disorders affecting
teeth, bones, the brain and the thyroid gland," reports
Scientific American editors (January 2008). "Scientific
attitudes toward fluoridation may be starting to shift,"
writes author Dan Fagin.
"Fluoride, the most consumed drug in the USA, is
deliberately added to 2/3 of public water supplies theoretically
to reduce tooth decay, but with no scientifically-valid
evidence proving safety or effectiveness," says lawyer
Paul Beeber, President, New York State Coalition Opposed
Fagin, award-wining environmental reporter and Director
of New York University's Science, Health and Environmental
Reporting Program, writes, "There is no universally
accepted optimal level for daily intake of fluoride."
Some researchers even wonder whether the 1 mg/L added
into drinking water is too much, reports Fagin.
After 3 years of scrutinizing hundreds of studies, a National
Research Council (NRC) committee "concluded that
fluoride can subtly alter endocrine function, especially
in the thyroid -- the gland that produces hormones regulating
growth and metabolism," reports Fagin.
Fagin quotes John Doull, professor emeritus of pharmacology
and toxicology at the University of Kansas Medical Center,
who chaired the NRC committee thusly, "The thyroid
changes do worry me."
Fluoride in foods, beverages, medicines and dental products
can result in fluoride over-consumption, visible in young
children as dental fluorosis -- white spotted, yellow,
brown and/or pitted teeth. We can't normally see fluoride's
effects to the rest of the body.
Reports Fagin, "a series of epidemiological studies
in China have associated high fluoride exposures with
"(E)pidemiological studies and tests on lab animals
suggest that high fluoride exposure increases the risk
of bone fracture, especially in vulnerable populations
such as the elderly and diabetics," writes Fagin.
Fagin interviewed Steven Levy, director of the Iowa Fluoride
Study which tracked about 700 Iowa children for sixteen
years. Nine-year-old "Iowa children who lived in
communities where the water was fluoridated were 50 percent
more likely to have mild fluorosis... than [nine-year-old]
children living in nonfluoridated areas of the state,"
writes Fagin. Levy will study fluoride's effects on their
Over 1200 professionals urge Congress to cease water
fluoridation and conduct Congressional hearings because
scientific evidence indicates fluoridation is ineffective
and has serious health risks.
