Don't miss
Dr. Brad Smith explains why orthorexia can become life-threatening even when the foods involved appear healthy.
The brief
Orthorexia begins with the pursuit of purity or health, but can turn ordinary nutrition choices into rigid rules that govern every meal and social decision.
Dr. Brad Smith distinguishes orthorexia from anorexia by its focus on purity rather than weight, while noting overlaps with anxiety, obsessive traits, and OCD.
The warning signs are less about a single ingredient than lost flexibility: obsessive planning, limited variety, intense guilt, social avoidance, and physical consequences.
The episode stresses that healthy-looking foods do not make severe restriction safe; malnutrition can bring organ complications and other life-threatening medical risks.
Treatment requires nutritional rehabilitation, psychotherapy, and medical monitoring, with orthorexia often documented under other specified feeding or eating disorder categories.
