Orthorexia

From the Greek "ortho", meaning straight, true, correct, and "orexia", referring to appetite.

Orthorexia Nervosa refers to a fixation on eating healthy food. The term does not denote an actual recognized diagnosis, and was coined by Dr. Steven Bratman to describe what he saw as a behaviour pattern that was just as destructive to one's health and life in general as the better known eating disorders.

As with most eating disorders, this one starts out with good intentions, and the person begins to follow a diet for what he or she believes are health related reasons. As the diet progresses, however, food choices become increasingly narrow, and supplements may become increasingly important. Social outings become restricted, as there is more and more attention to a restrictive diet. Lapses from the diet are generally followed by feelings of guilt and a possible move to an even stricter diet. The diet eventually comes to rule the person's life to the point that thoughts and activities all revolve around food. Where people with anorexia and bulimia focus on the quantity of food, people with orthorexia focus obsessively on the quality of food.
