The effects of young barley leaf powder(YBLP) on defecation frequency and fecal characteristics were studied in 61 healthy volunteers(34.1 •} 10.2 years old). The subjects were divided at random into 4 groups;non-dose control group(CG), low-dose group(LG), middle-dose group(MG), and high-dose group(HG). Total examination period was 4 weeks. After one week as the pre-test period, all groups were given a placebo diet for one week(placebo period). For the following 2 weeks(test period), CG, LG, MG and HG was given a placebo diet(not contained YBLP), a low-dose diet(1.5 g), a middledose diet(4.5 g) and a high-dose diet(6.0 g), respectively. In analysis, the subjects were screened under the condition that defecation frequency was below 7 times for one week of the pre-test period. This result showed that MG increased the defecation frequency and estimated fecal quantity significantly for the test period compared with those for the pre-test period, and HG increased them significantly for the test period compared with those for the pre-test period and placebo period. No clinical signs of toxicity recognized in the test period. These results suggest that YBLP has a fecal bulking effect and is useful for safety food material.

Many studies have been reported that dietary wheat bran, cellulose, resistant starch and inulin suppressed experimental colon tumors or cancer in rats. Dietary fiber reduces contact between the intestinal contents and mucosa, and leads to production of short-chain fatty acids, acetate, propionate, and butyrate, which reduce pH and the conversion of primary to secondary bile acids. Butyrate is the major source of energy for the distal colon and it reduces cell proliferation and induces apoptosis, factors that are associated with inhibition of the transformation of the colonic epithelium to carcinoma. On the other hand, dietary fiber is thought to protect against colorectal cancer in human but this view has been challenged by recent cohort studies that showed no protective effect.

In order to evaluate the available energy of dietary fiber materials, the fermentability was estimated from breath hydrogen excretion for 8 h after ingestion of 5g of dietary fiber materials in healthy human subjects. Fructo-oligosaccharide, of which available energy has been 2kcal/g, was used as a positive control, because it is not digested and is completely fermented by intestinal microbes. The following results were obtained based on the variable fermentability of each dietary fiber material. 1) Polydextrose, indigestible dextrin, partially hydrolyzed guar gum, lowered molecular alginate-Na and glucomannan were estimated as 1 kcal/g. 2) Nondigestible starch, which was resistant for the fermentation by intestinal microbes, was estimated as Okcal/g. 3) Cellulose, which is a water-insoluble dietary fiber, was slowly fermented and was estimated as l kcal/g. These results demonstrate that the method using breath hydrogen analysis is available to estimate the fermentability of dietary fiber in human gastrointestinal tract. However, it was not enough to collect expiratory gas of every 30 min period for 8 h after ingestion of dietary fiber materials. The fermentation of each dietary fiber material did not have been finished yet till 8 h after ingestion. Therefore, if the breath is collected for longer periods, the fermentability might increase and the available energy would be changed from the values as mention above. Another study with longer periods of breath collection will be needed.
