When eating healthy becomes an around-the-clock obsession, it could be a sign of trouble.
An extreme preoccupation with clean eating is an eating order called orthorexia nervosa. Though less well-known than anorexia nervosa or bulimia -- and not as well-documented -- a new study review says orthorexia can also have serious emotional and physical consequences.
"Orthorexia is really more than just healthy eating," said review co-author Jennifer Mills, an associate professor of health at York University in Toronto. "It's healthy eating taken to the extreme, where it's starting to cause problems for people in their lives and starting to feel quite out of control."
The review of published research from around the world on the disorder was recently published in the journal Appetite.
