Abstract
The aim was to determine the effect of extruded sorghum flour (ESF) on the adiposity and inflammation modulation in obese Wistar rats. Four experimental groups: normal control (AIN-93), obese control (HFD) and two tested groups (replacing 50% of cellulose and 100% of cornstarch by ESF in the HFD - HFDS50; and replacing 100% of cellulose and 100% of cornstarch by ESF in the HFD - HFDS100) were used. The luteolinidin and 5-methoxy-luteliolinidin were the main deoxyanthocianidins identified in ESF. The Lee index, percentage of adiposity, fatty acid synthase gene expression, TNF-α, blood levels of glucose and the adipocyte hypertrophy were lower in the groups treated with ESF when compared to HFD. The groups treated with ESF up-regulated the lipoprotein lipase, peroxisome proliferator activated receptor-γ gene expression and IL-10. ESF has potential as a functional food since it reduced the metabolic risk of obesity associated with adiposity and inflammation.
