From the authors’ conclusion: “There is strong evidence of the existence of sugar addiction, both at preclinical and clinical level. Our model has demonstrated that five out of eleven criteria for SUD are met, specifically: use of larger amounts and for longer than intended, craving, hazardous use, tolerance, and withdrawal. …
“From an evolutionary perspective, we must consider addiction as a normal trait that permitted humans to survive primitive conditions when food was scarce. As we evolved culturally, the neural circuits involved in addictive behaviors became dysfunctional and instead of helping us survive they are in fact compromising our health. From a revolutionary perspective, understanding the molecular, and neurological/psychological intricacies of addiction (sugar, drugs of abuse) will permit the discovery of new therapies (pharmacological and non-pharmacological) and possible management of at least one crucial factor in the occurrence of obesity.”
