Orthorexia Nervosa

Meaning

A proposed eating disorder characterized by an unhealthy obsession with eating food that one considers healthy, pure, or clean, often leading to restrictive dietary patterns that negatively impact physical and social well-being. This fixation moves beyond simple healthy eating into a pathological preoccupation that can result in nutritional deficiencies, social isolation, and significant psychological distress. It represents a clinical intersection of nutritional science and mental health.
