The effect of isomalto-oligosaccharides on human fecal flora was studied. Bifidobacteria and the Bacteroides fragilis group from human intestine could utilize isomalto-oligosaccharides but Escherichia coli and other bacteria could not. After the administration of isomaltooligosaccharides (13.5 g daily for 2 weeks) to healthy adult men and senile persons, the numbers of bifidobacteria in the feces increased. The consistency of feces was improved. These studies may support the usefulness of isomalto-oligosaccharides as components of new healthy foodstuffs for the improvement of the intestinal flora.
