Protective effect of soluble dietary fiber from Rosa roxburghii Tratt residue on dextran sulfate sodium‐induced ulcerative colitis by regulating serum metabolism and NF‐κB pathway in mice

Ulcerative colitis (UC) refers to an idiopathic chronic inflammatory bowel disease that starts with inflammation of the intestinal mucosa. Dietary fiber plays a crucial role in maintaining the normal architecture of the intestinal mucosa. In this study, the protective effect and potential mechanism of soluble dietary fiber from Rosa roxburghii Tratt residue (SDFR) on dextran sulfate sodium (DSS)-induced UC mice were explored.
