Cagaita fruit (Eugenia dysenterica DC.) and obesity: Role of polyphenols on already established obesity

Cagaita fruit (Eugenia dysenterica DC.) and obesity: Role of polyphenols on already established obesity
Polyphenol-rich cagaita (Eugenia dysenterica DC.) extracts (PCE) have previously shown to prevent body weight and adiposity induced by high-fat/high-sucrose (HFS) diet. Whether PCE also exerts protective effects in already developed obesity is unknown. In order to test this hypothesis, male C57BL/6J obese mice (previously feed with a HFS diet for six weeks) were treated with PCE at two doses, 7mg gallic acid equivalent (GAE)/kg body weight (PCE I group), and 14mg GAE/kg body weight (PCE II group) or water (HFS and Chow groups) by oral gavage for eight weeks. PCE did not affect body weight and adiposity of obese mice. However, PCE did protect against dyslipidemia, fasting hyperglycemia, and glucose intolerance, and attenuated both hepatic gluconeogenesis and inflammation as observed by the expression of tumor necrosis factor-α and transcriptional factor NF-κB. These results indicate that PCE improves glucose homeostasis of obese mice by attenuating hepatic gluconeogenesis and inflammation.
