Is fluoride in water toxic to babies' brains? A rigorous study raises alarms
from The Philadelphia Inquirer
A new study that suggests fluoride is harmful to developing brains is likely to fan the smoldering debate over the safety of adding the tooth-protecting mineral to public drinking water. The study by Canadian researchers, published Monday in JAMA Pediatrics, found that pregnant women who drank more fluoridated water had children with lower intelligence scores at ages three and four. An increase of a milligram of fluoride per day — the amount in about five cups of water — was linked to a loss of 3.7 IQ points for boys and girls.
