It seems like there are a lot of variables that need to be controller for here. For example, do people who adopt a vegetarian diet DEVELOP depression and mental illness? I doubt it. Much more likely that those people who are predisposed to emotional issues for whatever reason gravitate disproportionally to a vegetarian diet. I've been vegetarian for 20 years, but the health aspects of the diet are only about 10% of why I chose to be a vegetarian. I bet that's true for a large number of vegetarians.
