Running and eating disorders?

I've been checking out the Female Athlete Triad stuff, which is all pretty new to me. I am a female track and field runner and am familiar with eating disorders. My question goes out to all runners and coaches: what do you think about eating disorders amoung female runners? I've read stories where coaches have discouraged it and tried to help runners through it and others where coaches have encouraged weight loss to help running. Give me your views on this subject.
