Nut consumption and risk of cardiovascular disease, total cancer, all-cause and cause-specific mortality: a systematic review and dose-response meta-analysis of prospective studies
Per 28 g/day higher nut intake, pooled relative risk of all-cause mortality was 0.78 (95% CI 0.72–0.84).

Study design
Prospective-study meta-analysis
Population
20 studies (29 publications); 15 studies contributed to all-cause mortality analysis.
Measured outcome
All-cause mortality association
Finding
Per 28 g/day higher nut intake, pooled relative risk of all-cause mortality was 0.78 (95% CI 0.72–0.84).
Limitations
Not an absolute risk reduction or a life-years estimate. Confounding, dietary substitution and allergies matter; never recommend nuts to someone with a nut allergy.
Habit topics
Build a plant-rich plate
Interpretation
Research comparisons are not personal lifespan predictions. Years from different studies, habits, populations and outcomes cannot be added. Supporting studies do not validate the numeric estimate of another study.
