Avoidant Restrictive Food Intake Disorder
Commonly know as ARFID, avoidant restrictive food intake disorder is an eating disorder characterized by the inability for an individual to eat certain foods or types of food.
Although research on ARFID is not extensive, it has been found that the prevalence is between 0.5%-5% among the general population.
ARFID is often wrongly known as picky eating by people who don’t fully understand the disorder. Doing so minimizes and invalidates the real struggles that the individual has to face in trying novel foods, making it even harder for the person to expose themselves to their fear foods. It is therefore important to understand the real causes of the eating disorder and not label the strugglers as being difficult.
Diagnostic criterias do not include eliminating food from one’s diet due to religious beliefs, a medical condition, allergies or due to lack of access to food.
Causes
Unlike with anorexia nervosa and bulimia nervosa, the sufferer does not limit their food intake due to body image issues. Instead, the following factors are common triggers for selective eating:
- Sensory sensitivities causing strong aversions to the texture, taste and smell of certain types foods
- Past trauma when eating certain foods which may have resulted in vomiting, choking or severe stomach pain. As a result, the person can develop an intense fear of eating those same foods.
- Lack of interest in food due to low appetite or never being hungry, making meals feel more like a burden.
