谷物膳食纤维与结肠健康

Cereal Carbohydrates and Colon Health

膳食纤维(DF)为微生物生长提供均衡的能量和营养,这是维持结肠生态系统平衡所必需的。另外,膳食纤维的发酵,特别是丁酸发酵,有利于结肠健康。目前,结肠癌、炎症性肠炎和其他结肠紊乱疾病已经严重影响身体健康。作者综述了谷物膳食纤维中非淀粉谷物多聚糖、抗性淀粉,通过发酵产物短链脂肪酸和菌群的调节对于结肠健康的影响。

Providing balanced energy and nutrients for microbiota growth is esential for the maintenance of the colon ecosystem,and dietary fiber(DF) fermentation,particularly butyrogenic fermentation,augments colon health.Colon cancer,nflammatory bowel disease and other colonic disorders have become serious health issues.The effect of cereal DF,mainly nonstarch cereal polysaccharides and resistant starch on colonic microbiota,fermentation products of SCFA,microbiota modulation,as well as on colon health will be summarized.
