Consuming healthy food is a good practice, till the time it turns into an obsession because then it becomes physically and socially impairing. According to a recent study, those who have a history of an eating disorder, obsessive-compulsive traits, dieting, poor body image, and a drive for thinness are more likely to develop a pathological obsession with healthy eating or consuming only healthy food, known as orthorexia nervosa (ON).In the first exhaustive review of psychosocial risk factors associated with orthorexia nervosa, York University psychology researchers examined all studies published up until the end of 2018 in two popular databases.They looked at studies that examined how orthorexia nervosa is related to psychosocial risk factors that predisposed or made an individual vulnerable to or more likely to develop the condition. They then amalgamated all available findings for each risk factor to reach conclusions about which psychosocial factors were most reliably associated with the condition. Over time, they spend increasing amounts of time and effort purchasing, planning, and preparing pure and healthy meals, which eventually becomes an all-consuming obsession that interferes with other areas of life and results in weight loss.Other eating habits such as being a vegetarian or vegan also put individuals at higher risk for developing orthorexia nervosa. Lacto-vegetarians were at highest risk for the condition and people who are on a strict eating schedule, spending large amounts of time preparing meals, were also at greater risk.Findings of the study were published in the Journal of Appetite.
