Rating (out of 5): 3

Inulin is a naturally occurring prebiotic fiber found in various plants such as chicory root, onions, and garlic. Its use in supporting Inflammatory Bowel Disorders (IBD), which include Crohn's disease and ulcerative colitis, is primarily justified by scientific investigation rather than traditional medicine. Several studies have explored inulin's ability to modulate gut microbiota composition, increase beneficial bacteria like Bifidobacteria, and produce short-chain fatty acids (SCFAs) such as butyrate, which have anti-inflammatory properties and support colonic health.

Clinical evidence is still emerging, and the quality of evidence varies. Some small randomized controlled trials and animal studies have shown that inulin supplementation may decrease inflammation, improve gut barrier function, and ameliorate symptoms in IBD patients. For instance, research published in Alimentary Pharmacology & Therapeutics and Clinical Nutrition has indicated improvements in some clinical endpoints, such as reduced inflammatory markers and improved stool consistency.

However, the overall strength of the evidence is moderate (rated 3/5). Variability in patient response, potential gastrointestinal side effects, and the limited size of many studies are notable limitations. Larger, high-quality clinical trials are needed to confirm efficacy, determine optimal dosing, and clarify which IBD subgroups may benefit most. In summary, there is promising but not definitive scientific support for the use of inulin in IBD management, and it should be considered as an adjunct to, not a replacement for, conventional therapies.
