Knowra Orthorexia nervosa Orthorexia nervosa Orthorexia nervosa is an obsessive preoccupation with eating foods considered healthy that can cause nutritional harm or impair daily life. It is not a formal DSM-5-TR diagnosis.
Eating disorder : A mental disorder involving persistent disturbance in eating behavior that impairs health or functioning. Orthorexia is discussed alongside eating disorders, though it lacks formal DSM-5-TR diagnostic status.
Anorexia nervosa : An eating disorder involving persistent energy restriction, low body weight, and disturbance in body image or fear of weight gain. Anorexia is formally diagnosed and often centers on weight and shape, unlike orthorexia's stated focus on food quality.
Diet culture : Social beliefs and practices that moralize food and link body size or eating habits to personal worth. Moralized ideas about clean or virtuous eating can supply rules that rigidify into orthorexic patterns.
Proposed diagnostic criteria for orthorexia nervosa : Research criteria proposed to define persistent health-focused eating preoccupation that causes distress or impairment. Researchers have proposed criteria, but no consensus has established a formal DSM diagnosis.
Food choice : The process of selecting foods to eat, shaped by preferences, circumstances, beliefs, and needs. Orthorexia concerns food selection when health rules become unusually rigid and consuming.
Avoidant/restrictive food intake disorder : An eating disorder involving food avoidance or restriction that causes nutritional or psychosocial consequences without weight- or shape-driven motivation. This DSM diagnosis can involve health consequences of restriction, but its criteria differ from orthorexia's health-purity preoccupation.
Food purity : The belief that foods differ in moral or health value according to how natural, unprocessed, or uncontaminated they are. Purity standards can drive escalating exclusions in health-focused restrictive eating.
Orthorexia nervosa measurement scales : Questionnaires designed to measure orthorexic attitudes or behaviors in research and clinical assessment. Different scales operationalize the concept differently, complicating estimates and comparisons.
Obsessive-compulsive symptoms : Recurrent thoughts or repetitive behaviors associated with distress, rigidity, or difficulty disengaging. Intrusive food concerns and rule-bound eating can resemble obsessive-compulsive symptoms.
Obsessive-compulsive disorder : A mental disorder characterized by obsessions, compulsions, or both that cause significant distress or impairment. Similarities in rigidity do not establish that orthorexia is a form of obsessive-compulsive disorder.
