Adverse cardiovascular outcomes—including myocardial infarctions and strokes—are less common among individuals who eat fish instead of meat or poultry, according to a new study published in European Heart Journal. Vegetarian diets, meanwhile, may lead to a lower risk of cardiovascular disease (CVD)—but there was no significant difference in adverse cardiovascular outcomes.
Data from more 422,000 participants was taken from the UK Biobank database. While 55.4% of participants were women, 94.7% regularly ate meat as a part of their diet. The median follow-up period was 8.5 years.
Overall, the team found that diets where fish replaced meat or poultry were associated with a lower risk of CVD, ischemic heart disease, myocardial infarction, stroke and heart failure. CVD was less common among vegetarians, but the likelihood of adverse cardiovascular outcomes was not significantly changed.
