Introduction. Wheat is an important source of insoluble dietary fiber. These fibers are mainly concentrated in the envelope of the grain which constitutes the wheat bran (by-product obtained after refining). Objective.The aim of this study is to evaluate the effect of wheat bran on glucose metabolism in diabetic rat induced by streptozotocin (STZ). Materials and methods. The experimental study concerns the determination of dietary fibres in wheat bran and the in vivotest on twenty-four (24) females rats of the "Wistar" strain during four weeks, divided into four groups uniformly, two control groups and two other diabetic groups, receiving respectively a control diet and a diet supplemented with wheat bran. The evaluation includes changes in the following parameters; blood glucose, lipid profile and body weight and a histological study of the pancreas. Results. Wheat bran is rich in dietary fiber 39.5% (dry weight), the principal results of physico-chemical determinations show that it contains 5.44% water and 4.12% mineral matter with sodium (Na) and potassium (K) contents of approximately 3.87 mg/l and 3.44 mg/l respectively with 12.8% (dry weight) protein and a fat concentration of 5.40 % (dry weight). The results show a significant decrease (p<0.04) in blood glucose and body weight (p<0.05) in diabetic rats fed the wheat bran diet. No significant difference was observed for cholesterol and triglyceride levels. A significant difference (p<0.05) for HDL-C and LDL-C (p<0.001) is observed between the diabetic group with experimental diet and the non-diabetic group with control diet. Conclusion. This study shows the hypoglycaemic effect of wheat bran rich in dietary fibres on diabetic rats. Restraint wheat bran in the human diet is necessary under its therapeutic, economic and ecological aspects.
