Could eating less protein help you live longer? New review of 350 studies suggests surprising health benefits

A review of over 350 studies published July 31 in Cell Press Blue found that lower protein intake may improve metabolic health, slow biological ageing, and extend lifespan.

Researchers from the University of Wisconsin-Madison found that protein restriction improves metabolism, reduces cellular damage, and lowers risk of age-related diseases.

Study corresponding author Dudley Lamming said most people are sedentary and consume more protein than needed, which may have negative health consequences.
