    Wilson B, Rossi M, Dimidi E, Whelan K

    Published in American Journal of Clinical Nutrition

    Methodology

    Meta-analysis of 11 randomized controlled trials of prebiotics, including fructooligosaccharides, in IBS and functional bowel disorders.

    Key Findings

    Prebiotics did not improve global IBS symptoms, abdominal pain, bloating or flatulence compared with placebo; non-inulin-type prebiotics at low doses improved flatulence in subgroup analysis.

    Conclusions

    Prebiotics including FOS do not improve overall symptoms of IBS despite altering the microbiota.

    Limitations

    Few trials per prebiotic type; short durations; heterogeneous symptom scoring.
