Effects of comfort food on food intake, anxiety-like behavior and the stress response in rats.

摘要: It has been suggested that access to high caloric food attenuates stress response. The present paper investigates whether commercial chow enriched with glucose and fat, here referred as comfort alters behavioral, metabolic, hormonal parameters of rats submitted three daily sessions foot-shock stress. Food intake, anxiety-like behaviors, serum levels insulin, leptin, corticosterone, triglycerides were determined. decreased the intake chow, but kept unaltered food. During elevated plus maze (EPM) test, stressed increased number head dipping, entries into open arms, well time spent there, stretched-attend posture risk assessment. These effects independent type consumed. Non-stressed ingesting assessment well. Stress in center field delayed first crossing a new quadrant. plasma level reduced triglycerides, although consumption increases glucose, triglyceride leptin levels; no effect on was associated induced increase corticosterone attenuated when had concluded an anorexigenic is prevented upon Foot-shock also anxiolytic potentiated by ingestion evidenced both EPM tests.
