Research has shown that excessive dietary protein intake and high amounts of branch-chain amino acids (BCAA) in particular can accelerate aging and exacerbate chronic diseases of aging. In this episode University of Wisconsin Assoc. Professor Dudley Lamming talks about the cellular amino acid sensing mTOR pathway and its influences on aging and disease processes. The Lamming laboratory is making major contributions to establishing how amino acid intake affects cells and organ systems in health and disease. This research has important implications for optimizing health throughout the lifespan.
