Overview
The purpose of this study is to assess the amino acid oxidation dose-response relationship of ingested whole-food protein in healthy adults. In a randomized, crossover design, 20 young, healthy adult males and females aged 18-35 years, will consume a dinner consisting of 0.32, 0.74, and 1.32 g protein･kg BM-1 (corresponding to 1, 2, and 4 minced beef patties, respectively) during 3 separate experimental trials.The main study endpoint is the amino acid oxidation of ingested protein over a 24-h period.
