A recent study has reportedly concluded that taking omega-3—or n–3— fatty acid supplements does not improve heart health in patients with a high risk of cardiac problems who are already taking medicines to prevent them. Maria Carla Roncaglioni, et al., “n–3 Fatty Acids in Patients with Multiple Cardiovascular Risk Factors,” New England Journal of Medicine, May 9, 2013. Led by the Mario Negri Institute for Pharmacological Research in Milan, the study analyzed data from 12,513 Italian men and women randomly chosen to ingest either 1 g of n–fatty acids daily or an olive oil placebo. None of the study participants had experienced heart attacks but were deemed high risk because of diabetes, high blood pressure, high cholesterol, or obesity and many of them were taking statins or aspirin. After an average follow-up of five years, those taking the omega-3 supplements evidently did not reduce their risk of death or hospitalization from heart disease, compared with those who took the placebo.
