Drinking fluoridated water is not linked to lower cognitive abilities, researchers said in a new study.
Students who lived in areas that added fluoride to water tested better in school, John Robert Warren of the University of Minnesota and other researchers said in the paper, published Nov. 19 by Science Advances.
“We find robust evidence that young people who are exposed to typical, recommended levels of fluoride in drinking water perform better on tests of mathematics, reading, and vocabulary achievement in secondary school than their peers who were never exposed to sufficient levels of fluoride,” the researchers said.
“Based on our findings, we conclude that fluoride exposure─at recommended levels─does not negatively impact young people’s cognition. In fact, it may even have modest positive effects,” Warren, who has a doctorate in sociology, told The Epoch Times in an email….
