Association Between Fish Consumption and Risk of Cardiovascular Disease Mortality in Korean Men and Women: A Prospective Cohort Study

This prospective cohort study investigated the link between fish consumption and cardiovascular disease (CVD) mortality in 110,225 Korean adults. Over an average follow-up of 12.3 years, 669 CVD-related deaths were recorded. The study found that higher fish consumption was associated with a reduced risk of CVD mortality in women, with those consuming 4–7 servings per week having a 45% lower risk compared to those consuming less than 2 servings per week. Women consuming 7 or more servings per week also showed a significant reduction in cerebrovascular disease mortality. However, no significant association was found between fish consumption and CVD mortality in men. These results suggest that dietary recommendations for CVD prevention may need to be sex-specific.
