Later, serious academic study of orthorexia began to occur. Organizations like the International Federation of Eating Disorder Dietitians (IFEDD ) and the National Eating Disorders Association (NEDA) began to discuss the concept at meetings and in their published literature. Thom R. Dunn of the University of Northern California published a formal article on a case of orthorexia, and proposed diagnostic criteria. [Note: Dr. Dunn and I will be soon be publishing revised criteria that we expect to be definitive.] The authors of the DSM, the American Psychiatric Association’s classification and diagnostic tool, were even quoted as considering it for inclusion.
