Macro partitioning
Replacing animal protein with plant protein in the diet is associated with lower cardiovascular disease mortality and all-cause mortality, particularly when substituting processed red meat.
To support long-term heart health and longevity, prioritize plant-based protein sources (legumes, grains, nuts) over animal sources, especially processed red meats. You do not need to eliminate animal protein, but shifting the balance toward plants is linked to lower mortality risk. Ensure you are eating a variety of plant proteins to cover essential amino acid needs.
A high plant protein intake was inversely associated with all-cause and cardiovascular mortality... The substitution of plant protein for animal protein, especially that from processed red meat, was associated with lower mortality, suggesting the importance of protein sources.
Why this rating
Based on multiple meta-analyses of observational cohort studies; the paper notes inconsistent findings in some SRs and highlights that isolating protein per se is difficult.

More from this paper
- Dietary protein quality is determined by essential amino acid content and digestibility (DIAAS), with plant proteins generally having lower bioavailability than animal proteins due to antinutrients.Good
- High protein intake (>0.8 g/kg BW) does not negatively impact kidney function in healthy individuals, and may prevent bone loss when combined with adequate calcium and vitamin D.Moderate
