The prevalence of inflammatory bowel disease, particularly ulcerative colitis (UC), has increased dramatically in the past few years owing to a changed lifestyle. Despite various therapeutic treatments, management of the disease is still an issue due to several limitations, including cost and adverse reactions. In this regard, researchers and consumers are inclined towards natural herbal medicines and prophylactic agents. Of these, dietary fiber (DF) (polysaccharides) has become an important topic of interest owing to various putative health attributes, particularly for diseases associated with the large intestine, such as UC. To fulfil industrial and scientific demands of dietary fibers, waste utilization can prove advantageous. Here, the present review highlights recent comprehensive advances in dietary fiber from waste resources in improving UC. Additionally, their role in the gut-associated microbiome, pathway for metabolites synthesis, inflammation, and its mediators. Moreover, here we also discussed short-chain fatty acids (SCFAs) transport and epithelial barrier function along with the mechanism of inflammation regulation. Collectively, it depicts dietary fiber from waste resources that could regulate various cellular processes and molecular mechanisms involved in perpetuating UC and can be used as a promising therapeutic candidate.
