Fluoride is newly classified as a developmental neurotoxin by medical authorities in the March 2014 journal Lancet Neurology (a search for the word fluoride in this article will not produce results, we suggest you search for ride). The authors are Dr. Philippe Grandjean of the Harvard School of Public Health and Dr. Philip Landrigan of the Icahn School of Medicine.

The authors write “A meta-analysis of 27 cross-sectional studies of children exposed to fluoride in drinking water, mainly from China, suggests an average IQ decrement of about seven points in children exposed to raised fluoride concentrations.” The majority of these 27 studies had water fluoride levels which the US Environmental Protection Agency currently allows in the US – less than 4 milligrams per liter.
