Original Paper


Cafeteria diet (CAF) mimics human Western diet and has been used in animal models to study obesity. The purpose of this study is to demonstrate that our CAF model induces metabolic disorder related to obesity and affects recognition memory in Wistar rats. We also compared the intake of two different soft drinks, as part of the CAF, on recognition memory. Our results demonstrate that CAF-fed rats increased weight gain and visceral adiposity, and exhibited hyperglycemia, hypertriglyceridemia, high leptin and low insulin plasma levels. Moreover, CAF animals showed higher lipid peroxidation in the liver and developed non-alcoholic fatty liver disease. Surprisingly, the group fed with cola-based soft drinks presented an improvement in recognition memory, whereas animals fed with orange-based soft drinks showed worse performance in this task. Our data indicates that CAF induces obesity and affects recognition memory, but the composition of the diet interfere when the neurological function is evaluated.
