摘要
膳食纤维是一种特殊营养素,其本质是碳水化合物中不能被人体消化酶所分解多糖类物质。根据其水溶性可将膳食纤维分为可溶性膳食纤维和不可溶性膳食纤维;可溶性膳食纤维是既能溶解于水,又能吸水膨胀,并能被大肠中微生物降解纤维。可溶性膳食纤维可降血脂、降胆固醇及预防心血管疾病;降血糖,减少糖尿病发生;同时,其还能诱导肿瘤细胞凋亡,预防肿瘤发生和进展。该文从流行病学、临床试验及动物和细胞实验等方面综述可溶性膳食纤维生理功能及分子机制最新进展,并对未来研究进行展望。
Dietary fiber is a special nutrient. It is carbohydrates which can not be digested by enzymes to break down the polysaccharides. According to its water-soluble characteristics, dietary fiber can be divided into soluble dietary fiber and insoluble dietary fiber. Soluble dietary fiber can dissolve in water and swelling, and it also can degradated microbiaum in the large intestine. Soluble dietary fiber has effects of reducing blood lipids, lowering cholesterol and preventing cardiovascular diseases, reducing blood sugar and lowering diabetes. At the same time, it can induce apoptosis of tumor cells and preventing tumor occurrence and progression. In this paper, we summarized the progress in physiological function of soluble dietary fiber from epidemics studies, clinical trials, as well as animal and cell experiments, and the molecular mechanism of soluble dietary fiber in preventing diseases. We also make prospects for future research in the fields.
