No Evidence Fluoride In Drinking Water Harms IQ, Finds Decades-Long Study

Decades of Data Dispel Fluoride-IQ Myths

With years of controversy surrounding fluoride in drinking water, a groundbreaking study finally puts the debate to rest, confirming that community water fluoridation has no detrimental impact on IQ.

The Long-Awaited Revelation

A detailed study spanning 64 years has shown no evidence that fluoride in drinking water negatively affects children's IQ. Tracking over 10,000 individuals from their high school years into their 80s, this research discredits previous claims of fluoride's harmful effects on cognitive function.

Inside the Numbers

Conducted by researchers from the University of Minnesota, the study draws on longitudinal data from the Wisconsin Longitudinal Study. It links high school seniors' fluoride exposure to subsequent IQ assessments, effectively countering flawed prior studies based on international data from contexts unlike the US.

Impacts and Implications

Despite earlier misinformation, this study provides robust evidence aligning with major health authorities such as the CDC and ADA, reinforcing the safety and benefits of water fluoridation. Its findings aim to shift public opinion back in favor of this critical public health measure, amidst the backdrop of some US states removing fluoride based on discredited data.
