Researchers Find No Link Between Mercury Consumption And Risk Of Heart Disease

A U.S. study of two large cohorts of men and women in the United States found no link  between mercury exposure from fish consumption and increased cardiovascular disease risk. Researchers set out to determine the validity of speculation that exposure to methylmercury from fish increases the risk of cardiovascular disease. Earlier clinical studies were small and results were inconsistent. For their research, scientists looked at cases of coronary heart disease and stroke and analyzed toenail clippings provided by participants for mercury and selenium concentrations using neutron-activation analysis. “We found no evidence of any clinically relevant adverse effects of mercury exposure on coronary heart disease, stroke, or total cardiovascular disease,” researchers concluded.
