Fluoride Exposure May Increase the Risk of Cardiovascular Disease
There is some evidence that people in areas with very high natural fluoride levels in the environment are at higher risk of high blood pressure. For example, several studies found a potential association between hypertension and fluoride levels in regions where fluorosis is endemic. But the evidence for a link between high blood pressure and fluoride from other sources is far less clear. Several animal studies suggest a possible link between fluoride exposure and cardiovascular disease. One study found that consumption of fluoride-enriched salt increased children’s and teens’ cardiometabolic risk scores, which measures risk factors for cardiovascular and metabolic diseases like diabetes. However, because the study assessed salt intake, it serves as a poor comparison to fluoridated water intake studies.
