Nutrition is the consumption of adequate amounts of food necessary for the body to sustain life. Nutrition is an emotional as well as a physical need and this has led to the creation  of the concept of emotional eating. This form of eating, which emerged out of physical need, gave birth to eating disorders and the related concept of addiction. Eating disorders were not a topic that was emphasized much until the 20th century and were categorized and collected in the publication of DSM-5. Although eating addiction is not included in the DSM as a diagnostic criterion, it is widely used as a concept. Current research supports the concept of eating addiction and research  is still ongoing.
