Consuming nuts two or more times per week is associated with a significantly reduced risk of sudden cardiac death compared to rare or no consumption.
Aim to eat a small handful (about 1 ounce) of nuts at least twice a week. This habit is linked to a significantly lower risk of sudden cardiac death in men. You do not need to eliminate other foods to make room for nuts; just ensure your overall calorie intake stays stable. Focus on variety, as walnuts provide specific antiarrhythmic fatty acids.
Compared with men who rarely or never consumed nuts, those who consumed nuts 2 or more times per week had reduced risks of sudden cardiac death (relative risk, 0.53; 95% confidence interval, 0.30-0.92)
Why this rating
Large prospective cohort (n=21,454) with long follow-up (17 years) and multivariate adjustment, but observational design limits causal inference.
