Symptoms of orthorexia nervosa may include obsession with healthy eating, and emaciation among other things. Orthorexic subjects typically have specific feelings towards different types of food. They tend not to eat out as much because they do not trust the preparation of foods other than what they have prepared. The obsession for healthy foods could come from a number of sources such as family habits, society trends, economic problems, recent illness, or even just hearing something negative about a food type or group, which then leads them to ultimately eliminate the food or foods from their diet. According to the abstract of a 2004 study quoted on PubMed, a service of the National Institutes of Health, "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."
