摘要
Scope The availability of studies related to the effects of natural macronutrients on inflammatory bowel disease (IBD) remain relatively limited. This study investigates whether and to what extent the consumption of five different native starches alleviate the clinical symptoms and dysbiosis of gut microbiota associated with colitis. Methods and Results Using dextran sodium sulfate (DSS)‐induced mouse model of colitis, the potential effects of native potato starch (PS), pea starch (PEAS), corn starch (CS), Chinese yam starch (CYS), and red sorghum starch (RSS) on the clinical manifestations and dysbiosis of gut microbiota are studied. Compared to CS and RSS, the consumption of PEAS, PS, and CYS significantly diminishes clinical enteritis symptoms, including reduced disease activity index, and the alleviated degree of colonic histological damage. Furthermore, the analysis of gut microbiota reveals the significant prebiotic characteristics of PEAS, PS and CYS, as indicated by the maintenance of gut microbiota hemostasis and the inhibition of typically pathogenic bacteria, including Escherichia coli and Helicobacter hepaticus . Conclusion Starches from potato, pea, and Chinese yam alleviate colitis symptoms in a mouse model, and also show significant prebiotic characteristics. These findings suggest a cost‐effective and convenient dietary strategy for the management of IBD.
