Higher nut consumption is associated with a significantly lower risk of all-cause mortality, cardiovascular disease (CVD) mortality, coronary heart disease (CHD) mortality, and sudden cardiac death.

Incorporate nuts into your diet regularly. This meta-analysis of large cohort studies links higher nut intake (highest quantile vs. lowest) with an 19% lower risk of dying from any cause and a 27% lower risk of dying from heart disease. You do not need to eat extreme amounts; simply ensuring you are in the highest consumption group compared to non-consumers or low consumers appears protective.

Why this rating

Based on prospective cohort studies with moderate to low GRADE ratings due to heterogeneity and potential confounding, though large sample sizes.
