Macro partitioning
Higher intake of processed meat or unprocessed red meat is significantly associated with an increased risk of all-cause mortality, whereas poultry and fish intake are not significantly associated with all-cause mortality.
To support longevity, limit processed meats and unprocessed red meats, as higher intake is linked to a small increase in mortality risk. You do not need to avoid poultry or fish, as this study found no significant link between their consumption and all-cause mortality. Prioritize plant-based proteins and fish/poultry over red and processed meats.
Intake of processed meat (adjusted HR, 1.03 [95% CI, 1.02-1.05]; adjusted ARD, 0.90% [95% CI, 0.43%-1.38%]) or unprocessed red meat (adjusted HR, 1.03 [95% CI, 1.01-1.05]; adjusted ARD, 0.76% [95% CI, 0.19%-1.33%]) was significantly associated with all-cause mortality. Intake of poultry... or fish... was not significantly associated with all-cause mortality.
Why this rating
Large pooled cohort, long follow-up, rigorous adjustment.
