Resumo: | Dietary fiber requirements are met by only a small fraction of the population. There is need for supplemented foods to fill this gap. Rice bran (RB) is high in fiber and has antioxidant properties. The effects of rice bran fiber on several metabolic indicators and the antioxidant capacity of rice bran in rats was reported. Rats were divided into 4 dietary groups: Vitamin E-sufficient with (+VitE/RB+) or without (+VitE/RB-) rice bran; Vitamin E-deficient with (-VitE/RB+) or without (-VitE/RB-) rice bran. Food intake, growth and feed efficiency were similar in all groups but wet and dry fecal mass of the RB+ groups were 3 times higher than the RB- groups. Blood hemoglobin and liver iron were also similar among all groups. However, the liver VitE concentration of the rats of (-VitE/RB-) group was 10x lower than the (+VitE/ RB-) group. In contrast, liver VitE of the rats (-VitE/RB+) was only 2.6x lower. This effect of RB was also seen in erythrocytes since, catalase and glutathione reductase increased in the VitE deficient rats but RB prevented this increase. This study shows that dietary RB did not interfere with growth, feed efficiency and iron metabolism, it provided dietary fiber and laxation and partially prevented VitE deficiency.
