JAMA Pediatrics Study Finds Fluoride Exposure Linked to 1.63 IQ Point Drop in Children, Amid Robert F. Kennedy Jr.'s Opposition

Jan 6, 2025, 05:24 PM

A new systematic review published in JAMA Pediatrics has found an association between fluoride exposure and lower IQ scores in children. The review, which analyzed 74 studies from countries including China, Canada, and India, concluded that for every milligram per liter increase in urinary fluoride, children's IQ decreases by 1.63 points. The study has sparked debate, with some scientists criticizing its methodology and questioning its applicability to U.S. water fluoridation levels. Critics argue that many of the studies included in the review were of low quality and conducted in environments with other contaminants. Despite these criticisms, the findings have reignited discussions about the safety of fluoride in drinking water, especially as Robert F. Kennedy Jr., President-elect Donald Trump's pick for Health and Human Services Secretary, has expressed opposition to water fluoridation.
