A study on the effects of extruded sorghum bran (ESB) or raw sorghum bran (RSB) on biomarkers of glucose dysregulation, dyslipidemia, inflammation, and antioxidant potential induced by a high-fat diet (HFD) in rats was carried out. Four groups of male Wistar rats (six per group) consumed a basal diet (BD), which were supplemented with either lard at 310 g/kg (HFD) or lard and ESB at 180 g/kg (HFD + ESB) or lard and RSB (HFD + RSB), for 8 weeks. The intake of HFD supplemented with ESB or RSB hindered the fat storage in adipocytes of abdominal tissue, dyslipidemia and the loss of glucose homeostasis. A positive correlation between inflammation biomarkers (Interleukin-1β and Interleukin-6) and glucose homeostasis was observed, while a negative correlation between antioxidant capacity (TEAC) and Interleukin-1β and Interleukin-6 was observed. As a conclusion, the ESB or RSB may be intended as part of healthy diets.
