In this video uploaded by the from the Institute of Human Anatomy from Salt Lake Ciry, USA, Jonathan explains how your body absorbs protein. He discusses the differences between digestion and absorption, and how certain segments of the digestive system participate in these processes, as well as how this influences the type, amount, and distribution of the protein throughout the body. Does the timing and the type of protein even matter? It should be a fun one!
