Government Report Sparks Debate Over Fluoride Levels and Child IQ

A recent US government report links high levels of fluoride in drinking water to lower IQs in children, marking the first federal acknowledgment of such a risk. Based on international studies, it highlights the potential neurological impact of fluoride, prompting questions about public health protections and future research needs.

A U.S. government report has linked high fluoride levels in drinking water to lower IQ in children, stirring public debate. This is the first time a federal agency has acknowledged the neurological risks associated with high fluoride exposure, based on a review of global studies.

The National Toxicology Program's report, summarizing international research, indicates that water containing over 1.5 milligrams of fluoride per liter can negatively impact children's IQ. Although the report did not quantify the exact decrease in IQ points, it highlighted consistent findings across various countries.

While fluoride has long been praised for its dental health benefits, this report raises critical questions about potential neurological damage from high exposure, particularly in vulnerable groups like pregnant women and young children. Researchers call for more extensive studies and public health officials to reconsider current fluoride standards.
