It therefore also doesn't qualify when considering the typical conditions of abnormal dependence upon a substance tolerance and withdrawal.
At the same time, research has long found similarities between food intake and addiction. And just recently announced, the updated version of the Diagnostic and Statistical Manual of Mental Disorders, commonly called the DSM, will now formally include binge eating disorder as a new diagnosis.

This lack of clarity in the scientific literature prompted the publication of this cohesive look at the support for and against the application of the addiction model to food. This Biological Psychiatry issue was led by guest editors Drs. Dana Small and Ralph DiLeone, at the Yale School of Medicine. Their goal was to bring together original research fin
