Orthorexia

Orthorexia is an eating disorder similar to anorexia, though instead of an obsessive desire to lose weight, those who suffer from orthorexia have an unhealthy obsession with healthy eating. The word comes from Greek orthos, “correct or right”, plus orexis, “appetite”. In their search for dietary purity, orthorexics may become so restrictive about what they eat (for example, avoiding fatty foods, those containing preservatives, those with salt or sugar) that eventually they become as dangerously thin as an anorexic.
