Dietary fiber supplementation with psyllium or gum arabic reduced fecal incontinence in community-living adults.

Intervention Participants were allocated to receive 31 days of dietary fibre supplementation with psyllium 7.1 g/day (n=13); gum arabic 25 g/day (n=13); or placebo given as pectin 0.25 g/day (n=13). Supplements were mixed into fruit juice and divided into 2 servings for consumption during the morning and evening meals. Participants were instructed to maintain their usual diet. Those who were taking antidiarrhoeal medication were advised not to alter the type and amount during the study.
