The effect of fiber supplementation on irritable bowel syndrome: a systematic review and meta-analysis.

Abstract in brief

• The review found that soluble fiber significantly helps in reducing symptoms of irritable bowel syndrome (IBS), with patients being 86% less likely to remain symptomatic after treatment, while bran fiber showed no significant benefit.
• The analysis included 14 randomized controlled trials with a total of 906 patients and concluded that soluble fiber has a positive effect on IBS symptoms, whereas bran fiber does not.
• There was no evidence of harm associated with fiber supplementation, and the benefit was specifically linked to soluble fiber, not bran.]
