U.S. Report: Fluoride at Twice Recommended Limit Linked to 2-5 Point IQ Drop in Children

A recent U.S. government report, including a review by the National Toxicology Program and the U.S. Department of Health and Human Services, has linked fluoride levels in drinking water that exceed public health guidelines to lower IQ in children. The report indicates that fluoride concentrations at twice the recommended limit could result in a 2-5 point drop in children's IQ. This finding is expected to generate significant debate, as it challenges previous assertions by health bodies like the CDC, which have emphasized fluoride's benefits for dental health. The report marks the first time a federal agency has made such a determination with moderate confidence, highlighting potential public health implications for communities with naturally high fluoride levels, such as those with 1.5 milligrams or higher, in water. Some studies found that levels deemed safe by the WHO may also be linked to IQ loss.
