New Eating Disorder, Health Food Junkies

LONDON, England (WUSA) -- There's a new eating disorder out there--one where people are fixated on healthy eating. The official term for the condition is Orthorexic Nervosa.

"I am definitely seeing significantly more orthorexics than just a few years ago," said Ursula Philpot, chair of the British Dietetic Association's mental health group.

The condition, named by a Californian doctor, Steven Bratman, in 1997, involves rigid eating, which includes not touching sugar, salt, caffeine, alcohol, wheat, gluten, yeast, soya, corn and dairy foods.

The obsession can lead to some sufferers ending up malnourished, similar to anorexia nervosa.

Experts say those who suffer from the eating disorder are over 30, well educated and typically middle-class.
