CDC reverses decision on everyday chemical its been pushing for 60 years – now says it reduces IQ

The National Toxicology Program (NTP), which is part of the National Institutes of Health (NIH), has – after decades – indicated concerns regarding fluoride exposure and its potential impact on IQ in children.

Here’s a breakdown based on the information available up to October 9, 2024:

  • NTP Research and Findings: The NTP conducted a systematic review which concluded with “moderate confidence” in an association between higher levels of fluoride exposure (>1.5 ppm in drinking water) and lower IQ in children. This research was based on studies from various regions including Canada, China, India, Iran, Pakistan, and Mexico.
  • Public Health Implications: The findings have sparked discussions and legal actions. For instance, a federal judge has ordered the EPA to consider further regulating fluoride in drinking water due to these concerns. This reflects a growing recognition of the potential neurological risks of fluoride, especially at levels higher than previously recommended.
  • Broader Context: The addition of fluoride to drinking water has been a standard practice for reducing tooth decay, considered one of the great public health achievements. However, the conversation has shifted in light of this new research. While there’s a consensus on the benefits of fluoride for dental health, the potential neurodevelopmental risks, particularly at higher concentrations, are now under scrutiny.
  • Current Status: While the NTP’s findings have added significant weight to the debate over fluoride’s safety, especially at higher concentrations, the research also emphasizes the need for more studies particularly at lower concentrations commonly used in water fluoridation in many parts of the U.S.
