Interesting isn't it? What it comes down to is whatever works for you. However, when rebuilding from "terminal" some animal protein is essential to rebuild the DNA and RNA of the tissues. Meats and organ meats.
I've been in practice for almost 33 years and I have yet to see a healthy vegetarian. But I live in "North Country". The vegetarians up here are sick. They're pale, their adjustments don't hold and they die young. Usually early 60's. Maybe in the tropics and the warmer climes it'll work. Oh, I'd LOVE to try that. Lets send Doc Sutter down to the Carabean for two, three years to test the theory. I promise - I'll only eat veggies and fruit. See you in three years....
