The next time somebody tries to tell you that there is no scientific evidence proving that fluoride chemicals are harmful to human health, simply point them to a new study review recently published in the Institute of Environmental Health Sciences journal Environmental Health Perspectives that shows, for something like the 25th time now, that fluoride damages brain development and leads to significantly lower IQ levels in humans.

Researchers from both Harvard University's School of Public health and China Medical University in Shenyang jointly studied the effects of fluoride on children by evaluating 27 different fluoride studies. Upon review, the team found "strong indications" that fluoride exposure, particularly among developing children, is highly problematic for proper cognitive development and brain formation.

Children living in areas where public water supplies are artificially fluoridated had far lower IQ levels overall, based on the figures, compared to children living in non-fluoridated areas. And after accounting for other outside factors that may have influenced cognitive health and development, the team essentially determined that there is no denying a link between fluoride exposure and damaged IQ.

"[O]ur results support the possibility of adverse effects of fluoride exposures on children's neurodevelopment," wrote Anna Choi, a research scientist at Harvard, and her colleagues in their report. "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."

Another study published in the same journal back in 2010 found a similar correlation between fluoride exposure and cognitive development. A comparison of children between the ages of eight and 13 living in two Chinese villages, one fluoridated and one not fluoridated, revealed a 350 percent higher IQ level overall in the non-fluoridated village compared to the fluoridated village.

And again in India, researchers observed that fluoride chemicals cross the blood-brain barrier in children and "alter the structure and function of neural tissue." Published in the Journal of Medical and Allied Sciences, that particular study laid bare how pervasive fluoride actually is, in that the chemical deposits itself throughout the body and builds up over time, including in the brain.

"It's senseless to keep subjecting our children to this ongoing fluoridation experiment to satisfy the political agenda of special interest groups," says Paul Beeber, an attorney and president of the New York State Coalition Opposed to Fluoridation (NYSCOF). "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."
