While eating disorders do not receive the same amount of attention as other serious mental health illnesses, they are more common in teens than one might think. What's more, they found anorexia, bulimia, and binge eating go hand in hand with other mental illnesses.

In a recent brain imaging study, researchers at the Brookhaven National Laboratory found that binge eaters (those who compulsively overeat) react to their favorite foods differently than ordinary obese individuals.

A new study from the University of Haifa finds girls who spend more time on Facebook, the social networking Web site, are more likely to develop eating disorders.
