Published in American Journal of Clinical Nutrition
Methodology
Prospective cohort study relating dietary spermidine intake to 20-year all-cause mortality with independent validation cohorts.
Key Findings
Higher dietary spermidine intake was associated with lower all-cause mortality, an effect comparable to a 5-year younger age.
Conclusions
Observational data link spermidine intake to longer survival, but causality remains unproven.
Limitations
Observational design with residual confounding; dietary intake estimated from questionnaires.
Supplements Studied
Higher dietary spermidine intake was associated with lower all-cause mortality
Outcomes Measured
Higher dietary spermidine intake was associated with lower all-cause mortality
