Ioannina Researchers Show Fish Oil Doesn’t Prevent Heart Disease



A Greek scientific team led by Mosef Elisef of the University Hospital of Ioannina published a report in the Journal of the American Medical Association which disputed widely-held beliefs that fish products can help prevent heart disease and have healthy benefits from their oils.

The Greek researchers said the fatty acids have no impact on overall death rates, deaths from heart disease, or strokes and heart attacks. Omega-3 fatty acids, found in oily fish such as sardines and salmon, were considered to be a way of preventing heart disease and stroke, but analysis of previous clinical trials including more than 68,000 participants showed it is not associated with a lower risk of deaths caused by heart problems.

A decade ago, medical evidence suggested that boosting omega-3s, including the acids known as EPA and DHA, with food or supplements had a strong protective effect even though the mechanism wasn’t understood. However, according to the current research, individual nutrients in isolation, such as fish oil pills, do not help.
