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.

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
