Fish oil has no CVD benefit in people with diabetes

A 1g daily capsule is safe - but offers no added protection

A large study on the effects of fish oil and aspirin in people with diabetes has found that the oil supplements don't prevent first-time heart attacks or strokes.

And although aspirin does, the benefit is cancelled out by the higher risk of bleeds, according to a UK study presented at the European Society of Cardiology annual congress in Munich.

Almosty 15,500 volunteers were tested in the ASCEND study (A Study of Cardiovascular Events in Diabetes) to see if either treatment made a difference.

None of them had heart disease at the start of the study but all had diabetes.

In the fish oil portion of the study, half the patients took a daily 1g capsule of n-3 fatty acids and the rest took a capsule containing olive oil as a placebo.

Participants were tracked for close to 7.5 years on average.
