ReviewOverlaps in the nosology of substance abuse and overeating: the translational implications of "food addiction".
The obesity epidemic has led to the postulation that highly palatable foods may be "addictive" for some individuals. This idea is supported by the fact that there are overlaps in brain circuitry that underlie addictive behavior as well as overeating. ⋯ Further, we discuss preclinical data revealing that the addiction-like behavioral changes observed in response to overeating are concomitant with neurochemical changes that are similar to those observed in response to drugs of abuse. With this background and evidence in mind, we conclude this article with a discussion as to how "food addiction" research may translate into clinical strategies and pharmaceutical treatments useful in curtailing overeating.

Scientific interest in "food addiction" continues to grow due both to neurobiological and behavioral similarities between substance dependence and excessive food consumption. An important next step is to examine the addictive potential of highly processed foods. In this paper, we explore addiction-related changes in the modern food environment (e.g., increased potency, elevated speed of absorption), examine the historical and modern understanding of addictive substances as applied to hyperpalatable foods, and outline shared factors that increase the public health costs of both addictive drugs and certain foods.
