Comparative Study
[Physico-chemical properties related to gastrointestinal function of 6 sources of dietary fiber].
The physicochemical properties of the six sources of dietary fiber more commonly consumed in Mexico were studied. The knowledge of these properties may allow a prediction of the functional effect of the fibers on the GI tract. ⋯ PP and GM showed a higher water holding capacity and viscosity and a lower ion exchange capacity: we anticipate that these fibers would be more effective to regulate plasma levels of glucose and cholesterol in contrast, WB and SI with a lower water holding capacity and viscosity and a higher proportion of insoluble fiber would be more effective to increase fecal bulk. Fibers from DC and from cactus fiber isolate were intermediate in these responses.
