Barley (Hordeum vulgare) is sometimes used as a dietary intervention in Inflammatory Bowel Disorders (IBD), including Crohn's disease and ulcerative colitis, primarily due to its high content of soluble fiber, particularly beta-glucan. Scientific interest centers on barley’s ability to act as a prebiotic, fostering beneficial gut bacteria and increasing short-chain fatty acid (SCFA) production, both of which may help modulate inflammation in the gut. Several small clinical studies and animal models suggest that barley consumption can improve gut microbiota composition and enhance intestinal barrier function, factors often compromised in IBD. For instance, beta-glucan from barley has been shown to reduce inflammatory markers and promote mucosal healing in preclinical studies. However, robust, large-scale clinical trials in humans with IBD are still lacking, and available studies often use mixed dietary fibers rather than isolated barley. Moreover, whole grain barley contains gluten, which may not be suitable for all patients, especially those with celiac disease or gluten sensitivity, which can sometimes overlap with IBD.

In summary, while there is a plausible scientific rationale and some early evidence of benefit, the data remain preliminary and do not yet support strong recommendations for barley as a primary therapy for IBD. The evidence is currently rated as 2/5, indicating limited but promising support, and further research is needed to establish efficacy, optimal dosing, and safety in this population.
