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.
