I think there may be something to the theory of acid/alkaline balance, and I think in relation to the question of eating vegetation, it is probably how much is needed as opposed to needing it at all. I never got fat eating broccoli, for instance, and I never felt 'bad' after eating it - although I know people here have gotten used to eating mainly meat and fat and they feel bad after eating lots of fibre.

I personally don't need many veggies to feel good, but I do like a few non-animal products, particularly lemon juice in water, which is very alkalizing (sp). I feel fat and protein is more important, but I like to have a few plant things to feel best. Tomatoes and nuts are favourite.
