Brief Summary:
The purpose of this study is to investigate the effect of pectin, a kind of soluble dietary fiber, on clinical symptoms, gut microbiota and the immune status in patients with diarrhea-predominant irritable bowel syndrome

Condition or disease Intervention/treatment Phase
Irritable Bowel Syndrome Dietary Supplement: Pectin Dietary Supplement: maltodextrin Phase 3

Detailed Description:
Patients were randomized to receive either pectin or placebo. Treatment consisted of 6 weeks supplementation with pectin (fiber group) or placebo (maltodextrin). We evaluated the clinical symptoms, gut microbiota and the immune markers in two groups.
