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.
In conclusion, we found that higher nut consumption is associated with a lower risk of all-cause mortality, total CVD, CVD mortality, total CHD, CHD mortality and sudden cardiac death.
Why this rating
Based on prospective cohort studies with moderate to low GRADE ratings due to heterogeneity and potential confounding, though large sample sizes.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
