Fluoride Linked to Low IQ, Studies Show

New York - August 25, 2003 -- Children’s intelligence declines as their
natural drinking water fluoride levels increase, concluded a Chinese study in
the May 2003 journal, “Fluoride.�

Children scored inferior IQ’s even when fluoride levels were similar to that
added to U.S. water supplies to prevent tooth decay(1).

“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 blood-brain 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., Editor, Fluoride(5a).

Chemistry Professor Paul Connett, Ph.D., presented (5b
http://www.fluoridealert.org/nrc-paper.pdf ) and 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
http://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 fluoride, 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, the ADA is
disregarding new adverse fluoride studies,� says Attorney Paul Beeber,
President, New York State Coalition Opposed to Fluoridation. “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.

Couldn't have put it better myself. The journal "Fluoride" is not indexed by
PubMed or Ingenta, btw. Wonder if it exists?

You'll, of course, pardon me if I don't accept RSW's incredibly factual
statement above as valid refutation of the article.
