A factor of interest is the time of transit through the colon that determines the duration of the contact with the bacterial enzymes, and
the dietary fiber components that limit the extent of its decomposition (30–90% polysaccharides, mainly hemicelluloses and pectin)
and the main effect in the small intestine is associated with the
viscous polysaccharides, such as pectins and gums, which decrease
the assimilation of nutrients, while the insoluble components do
not affect in great extent
