i ate lots of unhealthy vegetarian food, including lots of soy, when i first became a vegetarian, i suffered from severe Depression a few years soon after. i think soy definitely has something to do with it. even now when i occassionally eat some soy, i still feel worse. soy really is bad for you, i can say this from my own experience. it really is a good for nothing as food, but it sure is bad for a lot of things!
