Macro partitioning
Substituting specific animal protein sources (eggs and red meat) with plant protein is primarily responsible for the observed reduction in overall mortality.
To maximize longevity, specifically target the substitution of eggs and red meat with plant-based proteins. Replacing 3% of energy from these sources with plant protein is linked to a 13-24% lower risk of death. This suggests that the type of animal protein matters, with eggs and red meat being the primary targets for reduction.
In particular, the lower overall mortality was attributable primarily to substitution of plant protein for egg protein (24% lower risk in men and 21% lower risk in women) and red meat protein (13% lower risk in men and 15% lower risk in women).
Why this rating
Large cohort, observational, but specific substitution analysis adds depth.
