Something about vegetable proteins I dont understand.
Heya, I was talking with my veghead sister in law and was asking about how they get enough protein in their diet and was told you do that by eating various kinds of vegetables so as to get a complete protein. I asked if she knew how much of the protein in plant matter was actually bio available to humans as we cant really digest the cellulose. She did not know how to answer and simply assumed that all the protein was there for us to use.
Can some one explain how this works? How is the vegetable protein delivered to our digestive tract and is it actually in a form we can make use of?
I found this bbc production that makes me think that not a lot of the protein can be used though they do not cover it specifically. [url=http://www.youtube.com/watch?v=rf_OWun4Y04&feature=youtu.be]Did Cooking Make Us Human ? (BBC Documentary) - YouTube[/url]
