As the editors of the prestigious medical journal anticipated, the newly published Canadian study is causing a stir.
The paper, which appears in JAMA Pediatrics links higher fluoride consumption by pregnant women with lower intelligence scores in their offspring. The findings represent the latest foray by researchers into fluoride safety, an emotionally fraught topic in both the U.S. and Canada.
The authors of the paper studied fluoride exposure for 512 mother-child pairs, about 40% of whom lived in fluoridated communities across six Canadian cities. They calculated fluoride levels in local water supplies and fluoride concentrations in the pregnant women’s’ urine.
