Government Agency Releases Report on High Fluoride Levels and Kids’ IQ [Video]

A U.S. government agency released a report on Wednesday that linked fluoride in drinking water at twice the recommended limit to lower IQ in children.

The report came from the National Toxicology Program, which is part of the Department of Health and Human Services. The Associated Press (AP) said the report includes information from studies conducted in Canada, China, India, Iran, Mexico and Pakistan.

The report found that drinking water containing more than 1.5 milligrams of fluoride per liter is associated with lower IQs in children. That limit is above the recommended fluoridation level set at 0.7 milligrams per liter of water by federal health officials since 2015. However, the World Health Organization (WHO) set a safe limit for fluoride in drinking water at 1.5, according to the AP.
