Avoidant and restrictive food intake disorder (ARFID) was recognized as a diagnosable feeding disorder in 2013.
Like the eating disorder anorexia, ARFID involves significant restriction or avoidance of food and significant weight loss or failure to gain weight in when weight gain would otherwise be expected. Unlike anorexia, however, ARFID does not involve any distress about body shape or size, or fears of fatness.
Many children go through phases of picky or selective eating, however most of these children will eventually eat when they get hungry enough and will consume enough calories to grow and develop properly. This is not the case for those with ARFID. For some, a limited variety of food can result in significant weight gain. ARFID can also result in problems at school or work, due to difficulties eating with others and extended times needed to eat. Three subtypes of ARFID have been identified although individuals may present with different variation.
