Macro partitioning
Higher dietary intake of plant protein is associated with a statistically significant reduction in overall mortality and cardiovascular disease mortality compared to lower intake.
To support long-term health and longevity, prioritize plant-based protein sources (legumes, nuts, grains) over animal proteins. Specifically, replacing about 3% of your daily energy intake from animal protein with plant protein is associated with a 10% lower risk of death. This benefit applies to both men and women and holds true across various health statuses and lifestyle factors.
greater dietary plant protein intake was associated with reduced overall mortality in both sexes... The association between plant protein intake and overall mortality was similar across the subgroups of smoking status, diabetes, fruit consumption, vitamin supplement use, and self-reported health status.
Why this rating
Large prospective cohort (n>400,000) with long follow-up (16 years) and rigorous adjustment for confounders, though observational design limits causal inference.
