People who received omega-3 fish oil supplements in randomized clinical trials had lower risks of heart attack and other cardiovascular disease (CVD) events compared with those who were given placebo, according to a new meta-analysis from Harvard T.H. Chan School of Public Health and Brigham and Women’s Hospital. Researchers found an association between daily omega-3 supplementation and reduced risk of most CVD outcomes, including heart attack, death from coronary heart disease, and death from CVD, but did not see benefit for stroke. In addition, higher doses of omega-3 fish oil supplements appeared to provide even greater risk reduction.
The study was published online September 30, 2019 in the Journal of the American Heart Association.
“This meta-analysis provides the most up-to-date evidence regarding the effects of omega-3 supplementation on risk of multiple CVD outcomes. 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,” said first author Yang Hu, a postdoctoral fellow in the Department of Nutrition at Harvard Chan School.

As a supplement taker, this was not very positive news. I have read a lot about omega 3 and omega 6 fats.
Omega 3 supplements have little or no effect on the risk of heart disease, stroke or death – according to new research from the University of East Anglia.
Increased consumption of omega 3 fats is widely promoted globally because of a common belief that that it will protect against heart disease.
But a new UEA-led Cochrane review – the international gold standard for high quality, trusted health information – finds that omega 3 supplements offer little, if any, benefit.
Omega 3 is a type of fat. Small amounts are essential for good health, and they can be found in the food that we eat. Continue reading
More good reasons for being careful about what we eat.
For some time now, nutritionist have recommended that we eat fish on a regular basis in order to get sufficient amounts of omega-3 fatty acids (specifically DHA and EPA). Not only are these nutrients good for the circulatory system, but they have also been proven to boost brain function, including both cognitive function and memory. Until fairly recently, scientists have not understood the mechanism by which omega-3 provides these effects.
A study to be published in the journal Applied Physiology, Nutrition, and Metabolism by researchers at the Center for Neuroscience at the University of Alberta in Edmonton, Canada found a specific link between docosahexaenoic acid (DHA) and memory.
The researchers fed one group of mice a diet supplemented with DHA and fed a second group a normal, healthy diet with no DHA supplementation. When the mice that received DHA supplements were examined later, it was found that the part of…
