Maybe the tin foil hat wearing crowd were right all along?
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.”

Discussion
Findings from our meta-analyses of 27 studies published over 22 years suggest an inverse association between high fluoride exposure and children’s intelligence. Children who lived in areas with high fluoride exposure had lower IQ scores than those who lived in low-exposure or control areas. Our findings are consistent with an earlier review (Tang et al. 2008), although ours more systematically addressed study selection and exclusion information, and was more comprehensive in a) including 9 additional studies, b) performing meta-regression to estimate the contribution of study characteristics as sources of heterogeneity, and c) estimating pooled risk ratios for the association between fluoride exposure and a low/marginal Raven’s test score.
