I don't think there's anything wrong with soy sauce. You consume so little of it. I don't use it every day and I don't even dip all my sushi in it because I like it mostly just the way it is. So when I have some, I don't worry about it at all. Soy sauce is way different from basing your diet on tofu, tempeh and soy protein phony foods. That reminds me, I once tried soy jerky and was really wierded out how it had the same taste and texture as real jerky. Plus I couldn't stop eating it. Something wrong with that, I say.
