Muscle aging amelioration by yeast protein supplementation was associated with gut microbiota

Skeletal muscle aging in elder people has been an overwhelming negative issue as the aging population increased. It was reported there may be close links among yeast protein (Saccharomyces cerevisiae) supplementation, gut microbiota and skeletal muscle aging. This study aims at characterizing the effects and mechanisms of yeast protein intake on muscle aging as well as figuring out the relationship between gut microbiota and the effects of yeast protein supplementation on muscle aging.
