The effects of wheat bran, Solka-floc and pectin on gastrointestinal transit time (TT) were investigated in ileorectostomized rats. After the operation, the rats were fed a fiber free diet (FF diet), a FF diet with 10% wheat bran (WB diet), a FF diet with 10% Solka-floc (SF diet) or a FF diet with 5% pectin (P diet) for 4 weeks (n=5, in each group). No significant differences were found in the growth rate of rats fed the FF diet, WB diet or SF diet. However, the growth of rats fed P diet decreased compared with the other hand, the WB diet or SF diet did not have any effects on TT. As it is well known that WB and SF diet decrease TT in the large intestine, over results here suggest that TT in the small intestine is delayed by feeding these dietary fibers.
