Alissa Cohen has put together a nice forum entry on the protein question, quoting some of our favorite rawfoodies.
I like her comments, it makes sense that veggies are our most absorbable route for protein. Where does all that famed cow muscle come from? Cows eat grass all day in their natural habitat. The gorilla who can toss a 300 pound man across the street, rips down trees all day eating their leaves.
Carnivores like the lion sleep all day to digest the most complex long chains of protein from meat. It takes a lot of energy to work with that, where as raw vegetable protein just floats right in and sits right down.
There must be a lot of loose ends to our knowledge base yet. The most certainty seems to come from a person who is backed by or in love with the meat/dairy industry.
I have never heard of someone going into the doctor and being told they now have a medical illness due to a protein deficiency.
I have heard of a vegan getting diabetes from relying on too much sugar and processed foods…hear that radio show on veganfreak. It has a lovely intro section, very well spoken, once the heavy metal started playing about 4 min. in I faded out, after the heavy metal he seems to feel the need to defend worrying about his health, repeating he is vegan for political reasons, that is first. His cholestorol problem is weird, I think some people make tons of it. I frequently tell people no plant products have cholestorol, people are surprised right when they are ready to attack the innocent and beautiful avocado or coconut or brazil nut.
The radio show points to a common problem of keeping a junked up diet after cutting out a dairy/meat product. One thing at a time.
