This is the best summary I could come up with:
The NHS recommends at least one portion of oily fish a week to help prevent the development of cardiovascular disease.
In order to find out how much protection it affords, a team of researchers in China, the US, the UK and Denmark monitored the health of more than 400,000 participants in the UK Biobank for an average of 12 years to estimate the associations between fish oil supplements and new cases of atrial fibrillation (irregular heartbeat); heart attack, stroke, and heart failure; and death in people with no known cardiovascular disease.
Published in the journal BMJ Medicine, the study found that for those with no known cardiovascular disease at the start of the monitoring period, regular use of fish oil supplements was associated with a 13% heightened risk of developing atrial fibrillation and a 5% heightened risk of having a stroke.
There was also a greater beneficial effect for older people and men with existing heart conditions, where the risk of transition from good health to death was 11% and 7% lower respectively.
“The traditional Mediterranean diet has been shown time and again to reduce the risk of heart attack or stroke.
This includes more fish – white and oily – and less red meat, along with plenty of fruit and vegetables, beans, lentils, nuts, seeds and wholegrains.”
