Impact of Animal and Microbial Protein Sources on Whole-Body Protein Metabolism in Healthy Adults Aged 18 to 45

What this Trial Is About

Researchers are investigating how different animal and microbial-based proteins affect whole-body protein synthesis in healthy adults aged 18 to 45. This study aims to better understand the nutritional quality of these protein sources and their role in maintaining health and body protein mass. The investigation uses a breath test and urine sampling methods developed by the research team to measure protein metabolism. Participants will be randomly assigned to consume one of three test beverages containing yeast protein, whey protein isolate, or collagen protein. Each protein is given as 0.9 grams per kilogram per day, divided into eight hourly drinks. After consuming the test beverage, their whole-body protein metabolism will be monitored over the following 8 hours. During the study, researchers will collect samples and data to measure phenylalanine excretion and oxidation over an 8-hour period as primary outcomes. Participants are expected to comply with study rules and will be monitored for any factors affecting metabolism. The total participation timeline includes the 8-hour metabolic assessment after protein consumption.
