Excellent research and explanations. My research comes from observing the health of vegetarians. Raw, vegan, vegetarian, it really didn't matter what type they were, they were structurally weak and needed animal protein. Randy, the midwest rep for Standard Process explained the protein uptake issue to me quite a while ago. There is a significant difference between animal and plant protein. So I don't know how Barefoot or Schulze do it. I don't see it work for the reasons described above. Doc
