"Researchers from Harvard have found that a substance rampant in the nation's water supply, fluoride, is lowering IQ and dumbing down the population. The researchers, who had their findings published in the prominent journal Environmental Health Perspectives, a federal government medical journal stemming from the U.S National Institute of Environmental Health Sciences, concluded that "our results support the possibility of adverse effects of fluoride exposures on children's neurodevelopment".

"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".
