Study Finds Vegan and Omnivorous Diets Are Equally Effective for Muscle Protein Synthesis

A recent study published in the journal Medicine & Science in Sports & Exercise conducted by Nicholas Burd and Andrew Askow from the University of Illinois Urbana-Champaign found that there is no difference in rates of muscle protein synthesis between individuals following vegan or omnivorous diets. The study involved 40 healthy adults who were placed on either a vegan or an omnivorous diet for nine days, with all meals provided by the research team. Both diets were found to be equally effective in supporting muscle gain, regardless of protein source or distribution throughout the day.

Surprisingly, the study also found that protein distribution across the day did not impact muscle synthesis in participants. Despite this, the research highlighted a common misconception among Americans, with only 57% believing it is possible to build muscle on a plant-based diet and 87% thinking that consuming animal products is necessary for adequate protein intake. The findings emphasize the need for more education about nutrition and challenge existing beliefs about the importance of protein sources for muscle growth.
