Plant Protein Tied to a Longer Life: Landmark 101-Country Study Redefines Diet and Longevity
A major new study spanning 101 countries has revealed that adults who consume a diet rich in plant-based proteins tend to live longer, while animal proteins remain crucial during early life. Published in Nature Communications, the international research provides some of the most comprehensive evidence yet linking dietary protein sources to lifespan, with possible lessons for Thailand’s evolving food landscape and health policies Nature Communications.
Across the globe, diets higher in plant protein were associated with significantly improved adult survivorship and overall life expectancy, especially when compared to diets where most protein comes from animal sources. Notably, the opposite effect was found among young children—animal-derived proteins offered unique survival benefits in the first years of life, likely due to bioavailable nutrients critical for development.
