Omega-3s help prevent heart disease

Omega-3s help prevent heart disease, according to new research from JAMA Internal Medicine.

Levels of plant based and seafood based omega-3 fatty acids in the blood lower the risk of dying from heart attack, as reported in the study led by Liana C. Del Gobbo, Ph.D., a postdoctoral research fellow in the division of cardiovascular medicine at Stanford University School of Medicine and senior author Dariush Mozaffarian, M.D., Dr.P.H., dean of the Friedman School of Nutrition Science and Policy at Tufts University in Boston.

Researchers from around the world combined their efforts to form the Fatty acids and Outcomes Research Consortium (FORCE). Together, they pooled 19 studies involving omega-3s and heart attacks.

From the review of the studies, they found that omega-3s were associated with a 10 percent lower risk of death from heart attack.

What did the authors have to say?

These new results, including many studies which previously had not reported their findings, provide the most comprehensive picture to-date of how omega-3s may influence heart disease,” said Del Gobbo, who conducted this study as part of her postdoctoral work with Mozaffarian. “Across these diverse studies, findings were also consistent by age, sex, race, presence or absence of diabetes, and use of aspirin or cholesterol-lowering medications.”

At a time when some but not other trials of fish oil supplementation have shown benefits, there is uncertainty about cardiovascular effects of omega-3s,” said Mozaffarian. “Our results lend support to the importance of fish and omega-3 consumption as part of a healthy diet.”

The authors concluded:

On the basis of available studies of free-living populations globally, biomarker concentrations of seafood and plant-derived ω-3 fatty acids are associated with a modestly lower incidence of fatal CHD.”

The study showing that omega-3s help prevent heart disease was published in JAMA Internal Medicine.
