Claimant: Gary Brecka
Claim: “Fluoride is a neurotoxin. Studies link it to lower IQ in kids, thyroid dysfunction, and weakened bone density.”
Rating: MISLEADING
Explanation: Studies cited by anti-fluoridation activists involve fluoride levels far exceeding those used in regulated U.S. water systems. At recommended levels, credible evidence does not show fluoride lowers IQ, harms the thyroid, or weakens bone density. Community water fluoridation remains a proven public health measure.
