The Effectiveness of a Diet With Beef as Key Protein Component Versus a Plant-Based Diet to Support Integrated Muscle Protein Synthesis Rates in Healthy Older Individuals
Sponsor: Maastricht University Medical Center
Summary
Muscles are composed out of proteins. These proteins in turn are composed out of smaller building blocks, called amino acids. By consuming a sufficient amount of dietary protein, a sufficient amount of amino acids become available to build new muscle proteins. The body's ability to build these new muscle proteins is of great importance to maintain muscle strength and function. Previous research suggests that a meal containing proteins from meat results in a better stimulation of the body's ability to build muscle proteins, when compared to a meal containing only plant-based proteins. However, these previous studies have only been performed following the ingestion of a single meal. As a result it is currently unknown how the muscles respond to a more prolonged ingestion of a diet containing animal/meat products, in comparison to a plant-based diet. Therefore, this study aims to investigate how fast new muscle proteins are being build when consuming a diet containing animal/meat products, in comparison to a plant-based (vegan) diet.
