Fluoridated water linked to higher cognitive scores in new study
A new study has found that children exposed to fluoride in drinking water scored higher on cognitive tests than those without such exposure. The research challenges recent concerns about fluoride’s impact on intelligence and cognitive development.
The practice of adding fluoride to public water systems began in the US in 1945. Its goal was to improve oral health in a cost-effective and equitable way. By the 1950s, many cities had adopted fluoridation after early trials showed a reduction in tooth decay. Studies by Public Health England and other researchers later confirmed these benefits.
The study provides fresh evidence that fluoride in drinking water may benefit cognitive performance. It also contradicts claims that recommended levels harm intelligence. However, the debate over fluoridation is likely to continue as policymakers weigh the latest research against ongoing concerns.
