US government study finds association between high levels of fluoride exposure and potential neurological risk
A US government report expected to stir debate concluded that fluoride in drinking water at twice the recommended limit is linked with lower IQ in children.
The report, based on an analysis of previously published research, marks the first time a federal agency has determined – “with moderate confidence” – that there is a link between higher levels of fluoride exposure and lower IQ in children. While the report was not designed to evaluate the health effects of fluoride in drinking water alone, it is a striking acknowledgment of a potential neurological risk from high levels of fluoride.
