Fluoride Levels Correlate to low IQs in Children New York State Coalition
Opposed to Fluoridation, 3/16/06 PO Box 263, Old Bethpage, NY 11804;
www.orgsites.com/ny/nyscof Children's intelligence declines as fluoride
levels in their natural drinking water increase, concluded a Chinese study
in the May 2003 journal, Fluoride. Even when fluoride levels were similar to
that added to U.S. water supplies to prevent tooth decay,(1) children scored
inferior IQ's. "As the fluoride levels in drinking water increased, the IQ
fell and the rates of mental retardation and borderline intelligence
increased," write researchers Xiang, et al. Tested were 512 children, aged
8-13 years from Wamiao, a high-fluoride village, and Xinhuai, a low-fluoride
village. The high-fluoride village was divided into five subgroups by water
fluoride levels, from 0.62 mg Fluoride per Liter to 4.38 mg F/L. As water
fluoride levels increased within the high fluoride village, IQ decreased.
"When the data from the 512 children in the two villages were considered as
a whole, a significant inverse correlation was found between IQ and the
level of fluoride in urine," the researchers report. "These results are
consistent with the findings recorded by Li at al.(3), Zhao et al.(4), and
Lu et al.(5) of an inverse correlation between intelligence and dietary
fluoride from either contaminated food or drinking water," they report.
Neither village experiences coal burning pollution nor do residents drink
brick tea, two common fluoride sources in China. Children with brain disease
or head injury history were excluded. Only water fluoride levels differed
between the two rural, low-income villages situated in the same province
(Jiangsu) and county. Neither blood lead levels( 2) nor urinary iodine
differed between the test groups. The authors also controlled for family
income and parental education Fluoride crosses the bloodbrain barrier
producing biochemical and functional impairment of the nervous system during
the developmental periods of infancy and childhood, the authors report.
"...despite growing evidence of serious neurotoxicity for both fluoride and
lead, U.S. safety standards for fluoride in water have been moving in the
opposite direction to those for lead in blood. From a scientific standpoint,
this is very difficult to understand or to justify," says organic chemist
Albert Burgstahler, Ph.D., and editor of Fluoride.(10) Chemistry Professor
Paul Connett, Ph.D., presented(11) a paper that explained these and other
fluoride adverse-effect studies, published since 1993, to the National
Academy of Sciences' National Research Council (NRC) panel studying
"Toxicologic Risk of Fluoride in Drinking Water"(6) on 8/12/03. (See Power
Point presentation at www.fluoridealert. org/NRC-final.ppt) The NRC will
recommend safe levels of fluoride in drinking water. "Two neurological
studies are particularly important," says Connett. "In 1995 Mullenix and
colleagues(7) discovered fluoride gets into the brain, contrary to former
beliefs. Then Varner and his team, in 1998,(8) found that even 1 part per
million fl uoride, the amount purposely added to U.S. water supplies,
facilitated uptake of aluminum into rats' brains causing amyloid deposits
similar to Alzheimer's patients," says Connett. The American Dental
Association (ADA), a union that represents dentists' interests, told the NRC
panel "... the ADA urges the subcommittee to support retaining the current
(1993) regulations... Since that time, there has been no published
scientific evidence that should change those conclusions," according to the
ADA news.(9) "Contrary to the ADA's assurances of fluoridation's safety,"
says Attorney Paul Beeber, President, New York State Coalition Opposed to
Fluoridation, "the ADA is disregarding new adverse fluoride studies. The ADA
can't be relied on by the media, legislators, health officials and the
public about fluoride and fluoridation's safety or bodily effects," says
Beeber.

Roger,

are you aware of the report on the origins of the use of flouride? as i
recall
flouride was a bi-product in the production of the A-bomb as per the
Manhattan
project. One of the first, if not the first place to test the use of
flouride was in
Newburg, NY (20 miles from my home). they understood then the dangers of
flouride but proceded anyway to promote using it as a method of dental care.
the report documents many of the dangers of this element that is so casually
put into toothpaste and water for a daily toxic dose.
