If the scientific link between fluoride exposure and a noted decreased in IQ is a conspiracy theory, then perhaps the Harvard researchers who just confirmed such a link should be tarred and feathered by the ‘evidence-based’ medical media. In a telling review of a variety of studies that have demonstrated just how significantly fluoride can damage the brain and subsequently your IQ, Harvard University scientists stated ”our results support the possibility of adverse effects of fluoride exposures on children’s neurodevelopment.”
The most outstanding component to the study is where it was published. Authors published their conclusion online in the July 20th edition of the prominent journal Environmental Health Perspectives, a federal government medical journal stemming from the United States National Institute of Environmental Health Sciences. The very same government that has continually asserted that water fluoridation is both perfectly safe and ‘effective’ at aiding the health of citizens who consume it on a daily basis.
In the past, the US government has actually been forced to call for lower fluoridation levels as previous research had also drawn a link between fluoride exposure and a host of neurotoxic effects. In the latest research by Harvard, it is made even more explicitly clear just how toxic fluoride can be to the body. In a written statement, researchers state:
“The children in high fluoride areas had significantly lower IQ than those who lived in low fluoride areas.”
Fluoride Lowers IQ, Sparks Tumor Growth
This should come as no surprise to those who have followed fluoride research over the past several years. As far back as 1977, for instance, epidemiological studies performed by the head of the Cytochemistry Section at the National Cancer Institute Dr. Dean Burk revealed that fluoride exposure led to increased tumor growth – even at levels as low as 1 ppm (the standard for United States drinking water). Beyond revealing an accelerated tumor growth rate of 25% in his research, fluoride was found to produce melanotic tumors, transform normal cells into cancer cells and increases the carcinogenesis of other chemicals.
In 1977, Dr. Burk estimated that fluoridation has actually caused about 10,000 deaths according to his research.
It will come as no surprise, then, that even the EPA — an agency charged with protecting the people — has classified fluoride as a substance with ”with substantial evidence of developmental neurotoxicity.” Perhaps the EPA is also run by blubbering conspiracy theorists. In another entry by study authors, it is explained how fluoride actually attacks the brain in unborn children and essentially launches a direct assault on their neurological development:
”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.”
But will the United States government answer to the study? As mentioned, many studies have exposed the same correlation of IQ-crushing fluoride intake. Paul Connett, Ph.D. and director of the Fluoride Action Network was one of the many activists to speak out regarding the last study to highlight the association. At the time, there were 23 former studies on the matter, and Connett felt that this 24th study was by far the strongest. And what was done? Unfortunately, it was brushed under the rug by mainstream health organizations who continue to assert that fluoride is perfectly safe. Some even recommend supplementing with fluoride pills.
In regards to the last breaking study, Connett stated:
“In this study we found a significant dose-response relation between fluoride level in serum and children’s IQ…This is the 24th study that has found this association, but this study is stronger than the rest.”
Will the latest Harvard-backed study be ignored by major public health organizations, or will serious change be initiated?

Harvard Study Finds Fluoride Lowers IQ – Published in Federal Gov’t Journal
NEW YORK, July 24, 2012
NEW YORK, July 24, 2012 /PRNewswire-USNewswire/ — 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), reports the NYS Coalition Opposed to Fluoridation, Inc. (NYSCOF)
“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.”
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 NRC 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.”
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 Legislationis 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)

Developmental Fluoride Neurotoxicity: A Systematic Review and Meta-Analysis
Anna L. Choi, Guifan Sun, Ying Zhang, Philippe Grandjean
Background: 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.
Objective: We performed a systematic review and meta-analysis of published studies to investigate the effects of increased fluoride exposure and delayed neurobehavioral development.
Methods: We searched the MEDLINE, EMBASE, Water Resources Abstracts, and TOXNET databases through 2011 for eligible studies. We also searched the China National Knowledge Infrastructure (CNKI) database, as many studies on fluoride neurotoxicity have been published in Chinese journals only. In total, we identified 27 eligible epidemiological studies with high and reference exposures, endpoints of IQ scores or related cognitive function measures with means and variances for the two exposure groups. We estimated the standardized mean difference (SMD) between exposed and reference groups across all studies using random effects models. We conducted sensitivity analyses restricted to studies using the same outcome assessment and having drinking water fluoride as the only exposure. Cochran test for heterogeneity between studies, Begg’s funnel plot and Egger test to assess publication bias were performed. Meta-regressions to explore sources of variation in mean differences among the studies were conducted.
Results: The standardized weighted mean difference in IQ score between exposed and reference populations was -0.45 (95% CI -0.56 to -0.35) using a random-effects model. Thus, children in high fluoride areas had significantly lower IQ scores than those who lived in low fluoride areas. Subgroup and sensitivity analyses also indicated inverse associations, although the substantial heterogeneity did not appear to decrease.
Conclusions: The results support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment. Future research should include detailed individual-level information on prenatal exposure, neurobehavioral performance, and covariates for adjustment.
