Orthorexia nervosa
(重定向自Orthorexic)
Orthorexia nervosa /ˌɔːrθəˈrɛksiə nɜːrˈvoʊsə/ (also known as orthorexia) is a proposed distinct eating disorder characterized by extreme or excessive preoccupation with eating food believed to be healthy. The term was introduced in 1997 by American physician Steven Bratman, M.D., who suggests that in some susceptible people, dietary restrictions intended to promote health may paradoxically lead to unhealthy consequences, such as social isolation, anxiety, loss of ability to eat in a natural, intuitive manner, reduced interest in the full range of other healthy human activities, and, in rare cases, severe malnutrition or even death.
