OBJECTIVE
This randomized, double-blind crossover trial evaluated the effects of a type 3 novel resistant starch (RS) versus wheat bran (WB) on faecal weight, frequency, and consistency in healthy adults.
METHODS
Following a 14-day baseline period during which subjects (n=14) consumed low-fibre (<2 g) test products, participants were assigned to receive 25 g RS or WB fibre daily for 14 days, then crossed over to the opposite treatment after a 7-day washout.
RESULTS
Daily faecal output increased from 128.8+/-68.7 g at baseline to 164.2+/-88.4 g with RS and 194.5+/-92.0 g with WB (both P<0.02 versus baseline). No significant differences among the three conditions were observed for bowel movement frequency. Faecal consistency ratings were increased with WB (P=0.001), but unchanged with RS.
CONCLUSIONS
Dietary RS and WB increase faecal output in healthy adults.
目的
本随机、双盲交叉试验评估了新型 3 型抗性淀粉（RS）与麦麸（WB）对健康成年人粪便重量、频率和稠度的影响。
方法
在 14 天的基线期内，受试者（n=14）摄入低纤维（<2 g）试验产品，然后将他们分配为每天接受 25 g RS 或 WB 纤维，持续 14 天，然后在 7 天洗脱期后交叉到相反的治疗。
结果
每日粪便排出量从基线时的 128.8+/-68.7 g 增加到 RS 时的 164.2+/-88.4 g 和 WB 时的 194.5+/-92.0 g（均 P<0.02 与基线相比）。在三种情况下，排便频率没有显著差异。粪便稠度评分随 WB 增加（P=0.001），但 RS 不变。
结论
饮食 RS 和 WB 可增加健康成年人的粪便排出量。
