Fish good for the heart even if it’s got mercury
Ingesting mercury found in most fish didn’t cancel the food’s heart-health benefits, says a Harvard study of people’s toenail clippings. Higher mercury exposure didn’t boost the incidence of coronary heart disease, stroke or cardiovascular disease, according to a study from the Harvard Medical School in Boston. The report, published last week in The New England Journal of Medicine, analysed toenails because they are a good indicator of the body’s absorption of mercury over the years, say researchers.
