This article (if its classified as that) came up on my yahoo home page about two new eating disorders

probably not a credible source but interesting to read about "orthorexia", which is basically just being really conscious about eating healthily to a point that could lead to other more serious eating disorders such as anorexia. It may be impossible to eat exactly the right things in the right amounts at the right times and never have some stress or anxiety over it, or to take it to the point of obsession. We are constantly putting labels on what is healthy or desirable, and they all seem to end up in the same ball of confusion, conflicting with all other ideas. You have to be skinny, but eat a lot; you have to work out, but not too much and not too little, and not look like you're trying too hard; you're supposed to be skinny but not look too skinny or you're labeled as having an eating disorder. the list goes on and on.
