Has a New Study Officially Declared That Fluoride Is a Neurotoxin?
No, a new study did not officially declare that fluoride is a neurotoxin.
The study in question, published in The Lancet Neurology in 2020, examined the effects of fluoride exposure on children’s intelligence. It found a correlation between higher fluoride exposure and lower intelligence quotient (IQ) scores, but the researchers did not definitively conclude that fluoride was the cause of the lower IQ scores. The authors acknowledged that other factors—such as poverty, nutrition, and education—could also contribute to lower IQ levels.
Additionally, the authors noted that more research is needed to determine whether fluoride is indeed a neurotoxin. The study did not account for the potential benefits of fluoride, such as its role in preventing tooth decay. The World Health Organization (WHO) has not declared fluoride a neurotoxin and still considers it safe and effective for use in public water supplies. The American Dental Association (ADA) has also not changed its stance on water fluoridation, stating that it remains an effective method to reduce dental caries in both children and adults.
