A new decades-long study has found no evidence that exposure to recommended levels of fluoride lowers children's cognitive skills. The research, which was published on Wednesday in Science Advances, challenges U.S. Secretary of Health and Human Services Robert F. Kennedy, Jr.'s earlier claim that adding fluoride to tap water may harm cognition. Citing fears that the chemical negatively affects brain development, several U.S. cities and states are either in the process of reevaluating the inclusion of fluoride in their water supply or have already moved to remove it. The new paper's findings, however, offer U.S.-based evidence that the public health intervention is safe, says University of Minnesota sociologist and study co-author John Robert Warren.
