Omega-3 fish oil found in salmon and tuna lowers the risk of heart diseases and reduces the risk of fatal heart attacks by eight percent – but has no effect on strokes, a new study found.<\/p>\n\n\n\n
The fatty acid rich oil supplements were seen to be particularly good at preventing heart attack, death from coronary heart disease.<\/p>\n\n\n\n
However, research – which reviewed several previous trials – revealed they didn’t affect the risk of stroke.<\/p>\n\n\n\n
Clinical trials analysed Harvard TH Chan School of Public Health and Brigham and Women’s Hospital in the USA revealed the link after trialing the supplements and compared them to a placebo.
What’s more, higher doses of omega-3 fish oil reduced the risk even more.<\/p>\n\n\n\n
The study has been published in the Journal of the American Heart Association.<\/p>\n\n\n\n
Author Yang Hu, a postdoctoral fellow from Harvard University, said: ‘This meta-analysis provides the most up-to-date evidence regarding the effects of omega-3 supplementation on risk of multiple CVD outcomes.<\/p>\n\n\n\n
‘We found significant protective effects of daily omega-3 supplementation against most CVD outcome risks and the associations appeared to be in a dose-response manner.’
Despite the positive result, and studies showing a link between eating fish and lower heart disease risk, results from randomized controlled trials (RCTs) like the one at Harvard have been inconsistent – two reviews published last year didn’t show a clear benefit.
But in this new broad analysis, the researchers that included three recently completed large-scale trials, which increased the sample size of 120,000 people from 13 trials from around the world. <\/p>\n\n\n\n
People who took daily omega-3 fish oil supplements, compared with those who took a placebo, lowered their risk for most heart disease except stroke, including an eight per cent reduced risk for heart attack and coronary heart disease (CHD) death.<\/p>\n\n\n\n
The risk appeared even lower at dosages above the 840 mg a day – still higher than the normal 250 – 500mg.<\/p>\n\n\n\n
Although safe doses are as high as 3,000mg per day.<\/p>\n\n\n\n
With several million people experiencing heart problems worldwide each year, even small drops in risk could save hundreds of thousands of lives.<\/p>\n\n\n\n
Although just stocking up on supplements wont keep hear problems at bay. Unsurprisingly the oils are likely best used as part of a balanced diet.<\/p>\n\n\n\n
‘Public health recommendations should focus on increasing fish consumption, having an overall heart-healthy diet, being physically active, and having other healthy lifestyle practices,’ noted Dr JoAnn Manson, senior study author and chief of the Division of Preventitive Medicine at Harvard Medical School.<\/p>\n\n\n\n
Nonetheless, she added: ‘This study suggests that omega-3 supplementation may have a role in appropriate patients.’
