Orthorexia?

My daughter struggled with this for 2 years while in college. I can assure you that there is nothing funny or normal about the thought process. To believe that something you eat is so bad for you that it makes you a horrible person to even think about eating it is painful to watch. It is not just restricting what you eat but if you eat it you will die and that is not an exaggeration, she really believed that. Instead of teaching and learning "everything in moderation" we hear that "clean and green" is the only way to go makes it too black and white. It is a good thing to eat healthy, avoid processed food, and chemicals BUT if for some reason you cannot avoid it, it has to be OK and for people suffering with this disorder it is not.
As much as MFP can help someone like me to keep track of the over eating and it does, it also was the thing that keep my daughter obsessed with calories, weight and exercise. Again everything in moderation and some people can't do that no matter how hard they try or how much they want to.
