Harvard Study Links Fluoride in Water to Lower IQ

In Uncategorized on August 29, 2012 at 4:20 pm

Harvard University researchers’ review of fluoride/brain studies concludes “our results support the possibility of adverse effects of fluoride exposures on children’s neurodevelopment.” It was published online July 20 in Environmental Health Perspectives, a US National Institute of Environmental Health Sciences’ journal (1),

“The children in high fluoride areas had significantly lower IQ than those who lived in low fluoride areas,” write Choi et al.

Further, the EPA says fluoride is a chemical “with substantial evidence of developmental neurotoxicity.

Senior author Philippe Grandjean says, “Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain. The effect of each toxicant may seem small, but the combined damage on a population scale can be serious, especially because the brain power of the next generation is crucial to all of us…This risk should not be ignored,” he says.

Fluoride (fluosilicic acid) is added to US water supplies at approximately 1 part per million attempting to reduce tooth decay.

Water was the only fluoride source in the studies reviewed and was based on high water fluoride levels. However, they point out research by Ding (2011) suggested that low water fluoride levels had significant negative associations with children’s intelligence.

Choi et al. write, “Although fluoride may cause neurotoxicity in animal models and acute fluoride poisoning causes neurotoxicity in adults, very little is known of its effects on children’s neurodevelopment.” They recommend more brain/fluoride research on children and at individual-level doses.

“It’s senseless to keep subjecting our children to this ongoing fluoridation experiment to satisfy the political agenda of special-interest groups,” says attorney Paul Beeber, NYSCOF President.  “Even if fluoridation reduced cavities, is tooth health more important than brain health? It’s time to put politics aside and stop artificial fluoridation everywhere,” says Beeber.   

After reviewing fluoride toxicological data, the National Research Council reported in 2006, “It’s apparent that fluorides have the ability to interfere with the functions of the brain.”

Choi’s team writes, “Fluoride readily crosses the placenta. Fluoride exposure to the developing brain, which is much more susceptible to injury caused by toxicants than is the mature brain, may possibly lead to damage of a permanent nature.”

Critics of this research review falsely claim it’s irrelevant because the studies represent high water fluoride levels.

But according to Paul Connett, PhD, co-author of The Case Against Fluoride, “Xiang et al, 2003, one of the 27 studies reviewed by Choi estimated that the threshold for the lowering of IQ was 1.9 ppm. A child drinking two liters of water at 1 ppm fluoride (2 mg of fluoride per day) would get more fluoride than some of the Chinese children drinking one liter of water at 1.9 ppm (1.9 mg/day).

‘Moreover another study ( Ding et al., 2012) found a lowering of IQ in the range of 0.3 – 3 ppm. No matter how you cut it – and no matter how much you want fluoridation to continue for emotional reasons – the science says that there is no adequate margin of safety – by any normal and rational toxicological standard – to protect ALL of America’s children from this serious end point. This outdated practice must be ended QUICKLY before we do further damage to our children and our future. If you must have fluoride, then brush it on your teeth and spit it out but don’t force it on the whole population via our drinking water.”

Fluoride accumulates in the body. Even low doses are harmful to babies, the thyroid, kidney patients and heavy water-drinkers. There are even doubts about fluoridation’s effectiveness (2).  New York City Legislation is pending to stop fluoridation. Many communities have already stopped

Infant formula when mixed with fluoridated water delivers 100-200 times more fluoride than breastmilk. (3)
