Stress-induced endocrine response and anxiety: the effects of comfort food in rats.

摘要: The long-term effects of comfort food in an anxiogenic model stress have yet to be analyzed. Here, we evaluated behavioral, endocrine and metabolic parameters rats submitted or not chronic unpredictable mild (CUMS), with access commercial chow alone food. Stress did alter the preference for but decreased intake. In elevated plus-maze (EPM) test, stressed were less likely enter/remain open arms, as well being more closed than control rats, both conditions pronounced given field time spent centre, independent diet; neither nor diet affected number crossing, rearing grooming episodes. stress-induced increase serum corticosterone was attenuated Serum concentration triglycerides unaffected by diet, although increased total cholesterol glucose. It is concluded that CUMS has anorexigenic effect. Chronic ingestion induced profile response. present data indicate combination food, common aspects modern life, may constitute a link among stress, feeding behavior anxiety.
