Psychology MCAT Practice Exam

Which eating disorder involves consuming non-food items?

1. Binge eating disorder

2. Anorexia nervosa

3. Pica

4. Bulimia nervosa

The correct answer is: Pica

The correct answer is indeed Pica, which is characterized by the persistent ingestion of non-nutritive, non-food substances over a duration of at least one month. This behavior goes beyond dietary habits and can encompass a wide range of materials that might include dirt, clay, chalk, or other inedible items. Unlike other eating disorders listed, such as binge eating disorder, anorexia nervosa, and bulimia nervosa, which involve food consumption in different maladaptive ways—such as excessive eating, restriction of food intake, or purging behaviors—Pica specifically relates to the consumption of items that are not considered food. This disorder may stem from nutritional deficiencies, underlying psychological disorders, or a combination of factors. Recognizing Pica is essential, as it can lead to serious health problems, including toxicity, infections, and gastrointestinal complications. Other eating disorders are defined by their relationship with food consumption, but they do not include the consumption of non-food items. Understanding these distinctions is crucial for identifying and treating the specific type of eating disorder effectively.
