Animal-based proteins have a higher quality due to their amino acid composition, which is similar to human skeletal muscle.

“now the quality of protein is defined by the amino acid composition and typically animal-based proteins have higher quality these are hard fast biological numbers the dietary protein in say um a steak is very similar to the protein amino acid in skeletal muscle so the quality of the proteins like eggs like whey protein like beef like poultry Those comp compositions are similar to the human body composition so they contain the amino acids in the appropriate ratios for skeletal muscle Health”
