Plant Protein Linked to Longer Lifespan: Global 101-Country Study Reframes Diet in Thailand
A landmark study spanning 101 countries finds that adults who eat more plant-based proteins tend to live longer, while animal proteins play a critical role in early life. Published in Nature Communications, the research is among the most comprehensive to date on how protein sources relate to lifespan. The findings offer lessons for Thailand’s evolving food landscape and health policy.
Across the world, higher plant protein intake is associated with improved adult survivorship and greater life expectancy, especially when compared with diets dominated by animal proteins. Conversely, the study shows that animal-protein may provide vital survival benefits during the first years of life, likely due to nutrients essential for growth and immune development.
