Fish oil IS good for your heart: taking daily supplements reduces the risk of fatal heart attacks by 8%, finds study
- Omega-3 fatty acids in fish oil can reduce inflammation
- Inflammation damages blood vessels and increases the risk of heart disease and strokes
- But research into the effects of fish oil on the heart has yielded mixed results
- The latest Harvard study examined data on more than 120,000 adults
- People who took the supplements ran an 8% lower risk of fatal heart attacks, but were no less likely to have a stroke
Omega-3 fish oil found in salmon and tuna reduces the risk of heart disease and reduces the risk of fatal heart attacks by eight percent – but has no effect on strokes, a new study found.
The fatty acid-rich oil supplements were found to be particularly good at preventing a heart attack, death from coronary heart disease.
However, studies – in which several previous studies were assessed – showed that they had no influence on the risk of stroke.
Clinical studies analyzed Harvard TH Chan School of Public Health and Brigham and Women & # 39; s Hospital in the US revealed the link after testing the supplements and compared them with a placebo.
Omega-3 fish oil supplements may not be all they need to be – such as stroke protection – but they do reduce the risk of fatal heart attacks, new research says
Moreover, higher doses of omega-3 fish oil further reduced the risk.
The study is published in the Journal of the American Heart Association.
Author Yang Hu, a postdoc from Harvard University, said: & # 39; This meta-analysis provides the most current evidence regarding the effects of omega-3 supplementation on the risk of multiple CVD outcomes.
& # 39; We found significant protective effects of daily omega-3 supplementation against most CVD outcome risks & # 39; s and the associations were found to be dose-response. & # 39;
Despite the positive result and studies showing a link between eating fish and a lower risk of heart disease, the results of randomized controlled trials (such as RCT & # 39; s) are inconsistent – two reviews published last year showed no clear benefit.
DO YOU NEED TO ADD FISH OIL TO YOUR DAILY REGIMEN?
Most health claims about fish oil concern the essential fatty acid omega-3.
Omega-3 is thought to have a positive, anti-inflammatory effect, which can benefit a number of health problems and protect people against diseases.
It is found in rich amounts in the meat of fatty fish, including salmon and trout.
These acids are important because the body cannot make them themselves, so they are often supplied by food or supplements.
Previous research has shown that fish oil is the most effective in supporting heart and brain health and in reducing joint pain.
But in this new broad analysis, the researchers who have included three recently completed large-scale trials, which have increased the sample size of 120,000 people from 13 trials around the world.
People who took omega-3 fish oil supplements daily, compared to those taking placebo, lowered their risk for most heart conditions except stroke, including an eight percent lower risk of heart attacks and cardiovascular death (CHD).
The risk seemed even lower at doses above 840 mg per day – still higher than the normal 250 – 500 mg.
Although safe doses are as high as 3,000 mg per day.
With millions of people suffering from heart problems worldwide every year, even small risk drops can save hundreds of thousands of lives.
Although only taking in supplements will not keep problems at bay. It is not surprising that the oils are probably best used as part of a balanced diet.
& # 39; Public health recommendations should focus on increasing fish consumption, having an overall healthy heart diet, being physically active and having other healthy lifestyle practices & # 39 ;, noted Dr. JoAnn Manson, senior study author and chief from the Preventive Medicine Department at Harvard Medical School.
However, she added: & # 39; This study suggests that omega-3 supplementation may play a role in suitable patients. & # 39;
