Watanabe N, et al. - Experts resolved to clarify the effect of resistant maltodextrin (RMD), a soluble dietary fiber manufactured from starch, on bowel movements based on stool frequency and stool volume. RMD intake led to a notable increased stool volume and stool frequency compared with placebo intake. It also displayed the ability to improve the sensation of complete/incomplete evacuation. Therefore, RMD illustrated a positive effect on bowel movements, contributing to normal bowel function. Yielded data would assist in the development of new criteria for choice of dietary fiber in the process of developing food products.
