Parorexia, also known as orthorexia nervosa, is a term used to describe an unhealthy obsession with eating only "pure" foods. Some synonyms for this condition include "health nut syndrome," "clean eating obsession," and "food perfectionism." People with parorexia may avoid certain food groups, such as grains or dairy, or strictly adhere to restrictive diets, such as vegan or paleo diets, often leading to malnutrition and physical health problems. The condition is often fueled by social media and celebrity influencers who promote extreme diets and lifestyles. As with any eating disorder, seeking professional help is important to overcome parorexia and develop a healthy relationship with food.
