In a study of bowel function in normal subjects wheat bran or cellulose was added to the diet for four weeks (16 g/day). Stool weight increased. Intestinal transit time did not significantly alter. Faecal bile acids did not increase but were diluted. It seems that the effect of these materials is to produce a bulky stool and that any symptomatic benefit they produce is secondary to this.
在一项针对正常受试者肠道功能的研究中,在饮食中添加麦麸或纤维素四周(16克/天)。粪便重量增加。肠道转运时间没有显著改变。粪便胆汁酸没有增加但被稀释了。这些物质的作用似乎是产生体积较大的粪便,它们产生的任何症状改善都是继发于此。
