References for the following statement, as requested, “Animal products have more bioavailable nutrients than plants, full stop. It’s not fashionable to say it but facts are facts.”
“..plant-based proteins generally exhibit lower digestibility, lower leucine content and deficiencies in certain essential amino acids such as lysine and methionine, which compromise the availability of a complete amino acid profile required for muscle protein synthesis. Based on currently available scientific evidence, animal-derived proteins may be considered more anabolic than plant-based protein sources.”
