Influence of indigestible fibers on glucose tolerance

L Monnier, TC Pham, L Aguirre, A Orsetti and J Mirouze

In eight patients exhibiting chemical diabetes mellitus with a poststimulative hypoglycemia, we observed that the pattern of the oral glucose tolerance test (OGTT) was improved when indigestible fiber was added to the oral glucose load. As compared with a standard OGTT, the peak blood glucose, expressed as per cent change from baseline, was particularly blunted by pectin or by cellulose phosphate but remained unchanged with cellulose supplementation. The time interval required to reach the blood glucose peak was significantly prolonged with pectin. The rate of blood glucose rise was reduced to a greater extent by pectin than by cellulose phosphate, which in turn was more efficient than cellulose. The blood glucose nadir expressed as per cent change from baseline was blunted by pectin, while the results were not significantly different after addition of either cellulose phosphate or cellulose. On the other hand, the plasma immunoreactive insulin did not show any significant change whether the glucose was given with or without one of the aforementioned types of fiber. From these results, it is concluded that an additional fiber intake may be of interest in the management of chemical diabetes. The use of pectin may diminish the poststimulative hypoglycemia.
