After watching a close friend battle anorexia, Sara Evans has signed on as an official ambassador for the National Eating Disorders Association. "Thankfully, I have never suffered from an eating disorder but am well aware of our society's obsession with body image," Evans said. "My passion for this cause is much more personal. I almost lost my best friend to anorexia. I am lending my voice as an entertainer, a mom and a friend because I want to bring great awareness to this cause."
