I have to avoid whey. After all it's dairy. Soy is ok in limited quantities. I think it's on the neutral list. I can't do soy protein shake from soy protein powder. I found that that a glass of soy milk from whole soy is alright. I know it sound like it's not much protein but using whole organic foods, even in small amount, will keep you going a lot longer than a whole lot of food that has little nutrients in it. Plus being able to eat red meat get's enough protein into the diet even if it's only a couple of times a week and chosing a natural meat makes all the difference.
