An increased need for dietary cysteine in support of glutathione synthesis may underlie the increased risk for mortality associated with low protein intake in the elderly
MF McCarty, JJ DiNicolantonio - Age, 2015 - Springer
Restricted dietary intakes of protein or essential amino acids tend to slow aging and boost
lifespan in rodents, presumably because they downregulate IGF-I/Akt/mTORC1 signaling …
