Certainly those who advocate for consuming it therapeutically, without acknowledging its well-known adverse health effects, may themselves be suffering from a fluoride-induced deficiency of intelligence. After all, is it intelligent to ignore the evidence supporting a hard and fast connection between increased fluoride exposure and lower IQ? For example... The study, titled Fluoride and childrens intelligence: a meta-analysis, published in the journal Biological Trace Element Research in 2008, set out to determine ...whether fluoride exposure increases the risk of low intelligence quotient (IQ) in China over the past 20 years. They reported: Sixteen case-control studies that assessed the development of low IQ in children who had been exposed to fluoride earlier in their life were included in this review. A qualitative review of the studies found a consistent and strong association between the exposure to fluoride and low IQ. The meta-analyses of the case-control studies estimated that the odds ratio of IQ in endemic fluoride areas compared with nonfluoride areas or slight fluoride areas. The summarized weighted mean difference is -4.97 (95%confidence interval [CI] = -5.58 to -4.36; p
