摘要
由于食物的精加工和生活习惯改变,运动减少,现代人的肠道健康状况下降,肠道疾病发病率不断增加,这已经影响到人们的身体健康和日常生活。肠道疾病的发生多与有毒有害物质在肠道内过久滞留,引起肠道环境改变恶化,进而损伤肠道细胞并引发各类炎症有关。本研究综述了59篇有关于膳食纤维和肠道相互作用的文献。研究表明摄入膳食纤维有助于促进肠道蠕动,保持大便顺畅,防止便秘,清除肠道内的有毒有害物质,保持肠道清洁和促进肠道内的益生菌生长等功效。而且,膳食纤维对肠易激综合征,炎症性肠病和肠癌等常见肠道疾病也具有一定的预防和治疗作用。综上,膳食纤维的摄入有益于保持肠道正常生理功能,修复和改善受损肠道环境,对于维护肠道健康有重要意义。
