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.â€

 

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)Â 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.
