Omega-3 fatty acids, found in oily fish such as sardines and salmon and once touted as a way of staving off heart disease and stroke, don't help after all, according to a Greek study.
Based on a review and analysis of previous clinical trials including more than 68,000 participants, Greek researchers whose report appeared in the Journal of the American Medical Association said the fatty acids have no impact on overall death rates, deaths from heart disease, or strokes and heart attacks.
This was true whether they were obtained from supplements such as pills, or from fish in the diet, said the researchers, led by Mosef Elisef at the University Hospital of Ioannina.
