Longevity: Eating Less Protein Linked to Healthy Aging in New Studies

Recent studies suggest that reducing protein intake may support healthy aging and longevity. A review published in Cell Press Blue analyzed over 350 laboratory and animal studies, finding that moderate protein restriction and limiting certain amino acids like methionine, isoleucine, and valine could extend life span in rodents. While short-term clinical trials linked protein restriction to improved blood sugar and reduced fat mass, no direct evidence supports its impact on human life span.
The findings suggest that protein needs vary by age, activity level, and overall health, and a one-size-fits-all approach may not be effective. Instead, protein restriction may trigger metabolic changes, such as raising FGF21 levels, which could boost metabolism and reduce inflammation, promoting healthy aging.
