Summary: An analysis of several large studies involving participants from more than 60 countries found that eating oily fish regularly may help prevent cardiovascular disease (CVD) in people with diabetes. at high risk, such as those who have had heart disease or stroke.
An analysis of several large studies involving participants from more than 60 countries, led by researchers from McMaster University, has found that eating oily fish regularly may help prevent cardiovascular disease (CVD) in people at high risk, such as those who already have heart disease. or stroke.
The key ingredient is omega-3 fatty acids, which the researchers found was linked to a reduction in the risk of major cardiovascular diseases such as heart attack and stroke by about one-sixth in high-risk individuals. eat two servings of omega-3 rich fish per person. week.
“There is a significant protective benefit of the study,” said co-lead author Andrew Mente, associate professor of research methods, evidence, and impact at McMaster and principal investigator at the Population Health Research Institute. fish consumption in people with cardiovascular disease.
No benefits were observed with fish consumption in people without heart disease or stroke.
“This study has important implications for fish intake guidelines globally. It shows that increasing consumption of fish and especially oily fish in patients with vascular disease may confer a modest cardiovascular benefit.”
Mente said people with a low risk of cardiovascular disease could still be moderately protected from cardiovascular disease by eating fish rich in omega-3s, but the health benefits were less pronounced than those with low cardiovascular disease. high risk.
The study was published in the journal JAMA Internal Medicine on March 8.
The finding is based on data from nearly 192,000 people in four studies, including about 52,000 with CVD, and is the only study to be conducted on all five continents. Previous studies have mainly focused on North America, Europe, China and Japan, with little information from other regions.
“This is the most diverse study of fish stocks and health outcomes in the world and the only study of sufficient numbers with representatives from high, middle and low income countries from all continents. habitats in the world,” said co-leader of the study. Salim Yusuf, professor of medicine at the Michael G. DeGroote School of Medicine and executive director of PHRI.
This analysis is based on data from several studies conducted by PHRI over the past 25 years. These studies were funded by the Canadian Institutes of Health Research, a number of different pharmaceutical companies, charities, the Population Health Research Institute, and the Hamilton Institute for Health Sciences.
