As a health care practitioner for over 23 years specializing in enzyme therapy, I can say unequivically I have yet to meet a truly healthy raw food vegan. I am only speaking from my clinical experience and events I have attended. In fact a few years ago I attended a presentation by a husband and wife team promoting a vegan raw food diet. Thye have several books out on the subject. The first thing I noticed was that the woman had edema in her legs. From a clinical perspective edema is a sign of a very low protein status - a protein deficiency. While I know certain plants and other non-animal sources of protein are high it is questionable whether or not someone should be on this type of diet. She spoke extensively about kale and other plants having a high protein content, yet she had a very visible protein deficiency!
I have researched nutrition for 40 years; have tried every type of dietary approach and have to agree with Dr. Mercola in that you have to discover what metabolic type you are. Even then it should be fluid enough for changes in your life. But the one thing that stands out in all of this is eating as much raw food as possible and that does include animal protein and animal dairy products when applicable. All the studies against animal protein were done with cooked products. Those are all flawed because of that aspect. Dr. Edward Howell, the pioneer of enzymes, advocated some raw animal products including meat. He cited the Inuit and their diet which is absent of fruits and vegetables, but exclusively high in raw meats and animal fats. How do you explain that? One should study the works of Aajonus Vonderplanetz who was diagnosed with 4 types of cancer when he was 19. That was more than 30 years ago. He tried a raw vegan approach to his cancer it never worked. Then he went with raw animal protein. He has worked with terminally ill cancer patients with great succes eating raw animal protein and dairy with very little fruits and vegetables and no grains.
