Omega-3 supplements, fatty acids in fish and that are recommended to prevent cardiovascular disease, people with diabetes do not really protect against these diseases, according to a large British study that contributes to different studies the same meaning.
More than 15,000 diabetics, without cardiovascular disease, participated in a study in Great Britain, led by researchers from the University of Oxford and funded by the British Heart Foundation. The results were published Sunday in the New England Journal of Medicine, the most prestigious medical journal in the United States.
No statistically significant difference
Half of the participants were prescribed a daily omega-3 capsule, while the other half unwittingly received a placebo capsule, which was simply olive oil. On average, patients were followed for a little more than seven years.
The study is all the more important because the sample is very large, more than 15,000 people. Moreover, the participants were randomly assigned to both groups, which is the most rigorous method to observe the final effect of a particular treatment.
The result is that the number of serious cardiovascular events, cancers or deaths in both groups was about the same. There was no statistically significant difference between the two. These results show that taking omega-3 fatty acids for people with diabetes does not reduce the risk of cardiovascular disease.
In January 2018, an analysis of ten studies with 78,000 people, published in the journal JAMA Cardiology, concluded that omega-3 & # 39; s cardiovascular diseases do not occur in people with increased risk, not just people with diabetes. Other studies, in 2012, 2010 and before, were in the same line. But doubt was maintained by studies that did not test according to a random placebo method.
