Higher consumption of fish and long-chain omega-3 fatty acids is associated with a significantly lower incidence of coronary heart disease and total mortality in women with type 2 diabetes.

If you have type 2 diabetes, aim to eat fish at least five times a week. This dietary pattern is associated with a significantly lower risk of heart disease and death compared to eating fish less than once a month. While there were past concerns about fish oil affecting blood sugar, current evidence suggests it does not worsen glycemic control. Focus on dark-meat fish like salmon or sardines, as they showed the strongest inverse association with heart disease in this study.

Why this rating

Prospective cohort study with large sample size (5103 women) and long follow-up (1980-1996), adjusted for multiple confounders, but observational design limits causal inference.
