Orthorexia indicates an unhealthy obsession with the choice of food ingested. This mean that the person can refuse to eat other foods they are not “good for the health” or to plan his diet at length in order to reduce the fats, salt, sugar, chemicals or other substances that it considers harmful to health. The aim of this behavior is to “choose” foods according to their quality or composition, thus allowing the person to be certain that they are “eating well” or “eating healthy”. The dietary rules imposed becomes more and more restrictive for the person and this induce social isolation and a loss of pleasure related to food.
