Recent studies have reignited the debate over the impact of fluoride in drinking water, suggesting a potential link between high fluoride exposure and lower IQ levels in children. A major review analyzing multiple global studies indicates that children exposed to elevated fluoride levels scored lower on IQ tests. While some experts argue that the science is contentious and based on shoddy data, others call for further examination of the health effects of fluoride. The findings raise concerns about water fluoridation practices, especially in light of calls from figures like Robert F. Kennedy Jr. to remove fluoride from drinking water. As the discourse surrounding this issue evolves, both public health officials and the scientific community continue to scrutinize the risks associated with fluoride exposure.
