A government report based on previous research has concluded a link between higher levels of fluoride exposure in drinking water and lower IQ levels in children. The report, released by the National Toxicology Program, suggests that water containing more than 1.5 milligrams of fluoride per liter is consistently associated with lower IQs in kids.
Fluoride is added to drinking water to strengthen teeth and prevent cavities, but the debate over its potential risks has been ongoing for decades. Researchers have raised concerns about the impact of higher fluoride levels on brain development, especially in developing fetuses and young children.
The American Dental Association, a strong advocate for water fluoridation, is still reviewing the report’s findings, while federal health officials have recommended a fluoridation level of 0.7 milligrams per liter of water.
Given these findings, there is increasing interest in exploring potential policy changes to protect the public from the dangers of high fluoride levels in drinking water. Pregnant women and parents of young children are urged to reduce fluoride intake to avoid potential risks to brain development.
The report highlights the need for further research to fully understand the impact of fluoride exposure on children’s IQ and overall health. As more evidence emerges, it will be important for policymakers to consider implementing measures to address the risks associated with high fluoride levels in drinking water.
