Abstract

Ingestion of different nutrients, such as fats and sugars, normally produces different effects on physiology, the brain, and behavior. However, they do share certain neural pathways for reinforcement of behavior, including the mesolimbic dopamine (DA) system. When these nutrients are consumed in the form of binges, this can release excessive DA, which causes compensatory changes that are comparable to the effects of drugs of abuse. In this article, we review data obtained with animal models of fat and sugar bingeing. The concept of "food addiction" is described and reviewed from both clinical and laboratory animal perspectives. Behavioral manifestations of addictive-like behavior and concomitant alterations in DA and opioid systems are compared for sugar and fat bingeing. Finally, in relation to eating disorders and obesity, we discuss how fat may be the macronutrient that results in excess body weight, and sweet taste in the absence of fat may be largely responsible for producing addictive-like behaviors that include a withdrawal syndrome.

  • Certain foods, particularly those rich in sugars and fat, are potently rewarding and can trigger addictive-like behaviours in laboratory animals.

    “certain foods, particularly those rich in sugars and fat, are potently rewarding (13) and can trigger addictive-like behaviours in laboratory animals (14,15).”

    From Obesity and addiction: Neurobiological overlaps (2013) · cites this paper as [15]

  • Highly palatable and processed foods and their cues stimulate brain reward and motivation pathways similarly to reinforcing drugs of abuse and, via conditioning, increase the likelihood of highly palatable food seeking and consumption.

    “Such highly palatable and processed foods and their related associations or ‘cues’ stimulate the brain reward and motivation pathways just as reinforcing drugs of abuse and via learning/conditioning mechanisms increase the likelihood of HP food seeking and consumption”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
