Popis: In order to study the mechanism of the dietary fibre action on the intestinal transit in man, the chemical nature together with the physicochemical and in vitro fermentative properties of five fibres were evaluated and then related to the effects of the latter on the orocaecal transit time (OCTT) and the orofaecal transit time (OFTT) in healthy volunteers. The results showed that the fibre water-binding capacity might be involved in the OCTT and an increase was observed with a fibre-supplemented diet. The fibres, which were capable of decreasing the OFTT, could act by a mechanical effect if they were not fermented in vitro. However, the partly degradable fibres might also change the OFTT via their products of fermentation. A large production of propionic and butyric acids, in particular, could be responsible for the effects of some fibres on the intestinal transit.
