The effect of cereal cakes containing an inner-layer fraction of barley bran on defecation habits in healthy young female volunteers was estimated by two kinds of intervention studies. In the studies, the barley bran cereal and two placebo cereals, 1 and 2, were used. <BR>In the first intervention study, fifty healthy subjects were divided into the two groups of 25 each: the constipation group and non-constipation group, and were given the barley bran cereal(dietary fiber(DF) 3.91g) and placebo cereal 2(DF 0.80g) for a week in a crossover manner. The daily intakes of DF in the barley bran ereal diet and the placebo cereal diet were, 11.3g and 8.9g in the constipation group and those values were 11.4g and 8.Og in the non-constipation group, respectively. Irrespective of constipation or nonconstipation, the frequency of defecation and the fecal volume in the barley bran cereal group were significantly increased compared with those in the placebo group. <BR>On the other hand, the second intervention study was performed mainly to clarify the effect of barley bran cereal on the fecal components. The subjects of 6 healthy females with nonconstipation tendency were given the barley bran cereal or placebo cereal 1(DF 0.1 lg) and 2 with a completely randomized crossover manner. They received the diets of cycle menu containing DF 8.1±1.6g/day according to their usual diets. The results showed that the average fecal volume and other parameters were not significantly different among the placebo cereals 1, 2 and the barley bran cereal, because of small number of subject and a large individual variation. <BR>Although the correspondent result was not obtained in the two kinds of intervention studies, the first intervention study suggest that the ingestion of barley bran cereal to healthy young females with constipation tendency does improve effectively their defecation habits by preventing constipation.
