Rethinking Fluoride

New research found an association between pregnant women who drank fluoridated tap water and reduced IQ scores in their children, causing a stir in the public health community. Flouride is added to more than 2/3 of drinking water in the US to prevent tooth decay and reduce cavities. 

In a comparison of 400 pregnant women who lived in cities with and without fluoridated water, researchers found that fluoride intake was associated with a slight drop in children’s IQ.

“There is clearly an association. It by no means proves definitively that this is a risk,” says Dmitri Christakis, editor of JAMA Pediatrics, which published the study.
