Protein is an essential component of a healthy eating pattern because it supports the growth, development, and maintenance of skeletal muscle. While animal-derived protein has the advantage of containing more amino acids that promote hypertrophy – particularly leucine – research suggests that plant-based proteins can be more viable for supporting muscle than previously thought. In this Aliquot, Dr. Stuart Phillips shares how his views on plant protein have evolved through his research on muscle protein synthesis and provide tips for ensuring that your leucine source is safe and low in contaminants. In this Aliquot, Dr. Stuart Phillips and I discuss the ins and outs of dietary protein and provide tips for ensuring that your leucine source is safe and low in contaminants.
