Abstract

To propose a diagnostic proceeding and to try to verify the prevalence of orthorexia nervosa (ON), an eating disorder defined as "a maniacal obsession for healthy foods". 404 subjects were enrolled. Diagnosis of ON was based on both the presence of a disorder with obsessive-compulsive personality features and an exaggerated healthy eating behaviour pattern. Of the 404 subjects examined, 28 were found to suffer from ON (prevalence of 6.9%). The analysis of the physiological characteristics, the social-cultural and the psychological behaviour that characterises subjects suffering from ON shows a higher prevalence in men and in those with a lower level of education. The orthorexic subjects attribute characteristics that show their specific "feelings" towards food ("dangerous" to describe a conserved product, "artificial" for industrially produced products, "healthy" for biological produce) and demonstrate a strong or uncontrollable desire to eat when feeling nervous, excited, happy or guilty.
