(BOSTON) -- According to a new study in the New England Journal of Medicine, eating omega-3 fatty acids is good for the heart and can lower the risk of cardiovascular disease. But fish also contain methylmercury, which has been linked in the past to an increase in the risk of cardiovascular disease.
To determine if methylmercury levels were associated with cardiovascular disease, the authors measured levels of it in the toe clippings of almost 7,000 people. The levels of mercury did correlate with reported fish consumption, but the authors found that there were no differences in the rates of heart disease, stroke, or cardiovascular disease in general between people with low or those with high levels of methylmercury.
Therefore, there are no clinically relevant negative effects of mercury exposure on cardiovascular disease in adults, at least at the levels seen in this study.
