The relationship between quality protein, lean mass, and bone health

Background The amount of quality protein (Essential Amino Acids (EAA): Protein) intake, and distribution of that protein to a meal, could play an important role with regard to lean mass (LM), bone mineral density (BMD), and bone mineral content (BMC). Research has demonstrated that muscle protein synthesis (MPS) is maximally stimulated at ~10g of EAA per meal (Cuthbertson, et al. 2005). A cross sectional study sought to determine the relationship between the amount of quality protein consumed in 24 hours and the amount of times the ~10g EAA threshold was reached at a meal, with respect to LM, BMD, and BMC.
