Orthorexia Nervosa is characterized by specific behaviors frequently related to other psychopathological conditions, such as Obsessive-Compulsive Disorder (OCD) and Eating Disorders (EDs). Whereas ON can mainly be described as an excessive concern regarding healthy food, the study's principal aim was to investigate if ON could be considered a condition related and differentiated from worry, other than OCD, EDs, perfectionism, anxiety, and depression.
