Eric discusses protein quality: what it is, what affects it, and how much it does (or doesn’t) matter from a practical perspective. His segment summarizes the research directly comparing a wide range of protein sources, and provides practical strategies for protein source selection in vegan, vegetarian, and omnivorous diets.
