Psychiatry Advisor discusses “orthorexia nervosa,” the “disorder” of “obsessively” researching about and eating healthy foods. About 72% of Americans search for health information online, and with respect to the prevalence of the new “disorder” in the general population Psychiatry Advisor quotes Karmpaul Singh stating that “generally 5-12% is something researchers can agree on.”
The name for the “disorder” was reportedly coined by a physician in 1997, and is not in the Diagnostic and Statistical Manual of Mental Disorders. Singh is a PhD student in psychology at the University of Manchester who has been studying health behaviors.
