Fish oil supplements 'do NOT cut risk of heart attacks and strokes'

Scientists claim fish oil supplements do not cut the risk of heart attacks and strokes despite being widely used and even prescribed for prevention.

A review of 20 studies involving almost 70,000 patients concluded that taking omega-3 fatty acids derived from fish oil had no significant effect on rates of heart attacks, strokes and heart-related deaths.

Previous trials have had conflicting results about whether supplements may protect the heart. But fish oil supplements are approved on the NHS to prevent heart attack survivors from having a second attack and recommended in official guidelines.

Omega-3 polyunsaturated fatty acids (Pufas) are known to fight inflammation, one of the key processes that contribute to narrowing of the arteries. Researchers conducting the new study analysed data on 7,044 deaths, 3,993 heart-related deaths, 1,150 sudden deaths, 1,837 heart attacks and 1,490 strokes.

The results, published in the Journal of the American Medical Association, showed no evidence of risk reduction associated with omega-3.
