Effect of dietary steamed and cured sweet potato slices on bowel movement in female students

Abstract

The impact of dietary steamed and cured sweet potato slices (100 g/day for 2 weeks) on bowel movement was examined in 84 Japanese female students, comprising a constipation group (n=15) and a non-constipation group (n=69). During the test period, the subjects recorded their bowel movement themselves status daily. Subjects completed a food-frequency questionnaire and were given a physical examination once a week. In all subjects, it was observed that the intake of the test food significantly increased the number of days of stool frequency, amount of stool, flatus, and the proportion of subjects who had soft stools.
