Caloric Restriction in Primates and Lifespan Extension
Caloric restriction in primates has been studied through four investigations, showing varied results. While the UW study reported significant benefits like delaying diseases and improving survival with 30% calorie restriction, the NIA study didn't exhibit the same outcomes. The contrasting diets in the studies, with UW's processed diet and NIA's healthier plant-based diet, played a critical role in the differing results. The disparity hints at caloric restriction being more beneficial for those with poorer dietary quality.
