益生菌与益生元

典型的益生菌是乳酸杆菌,包括双歧杆菌、乳酸菌等。这类物质能够维持肠内环境的平衡、预防感染、缓解乳糖的不耐性、促进免疫系统。而另外一类对双歧杆菌等益生菌有促进作用的物质,被称为益生元,它们具有非消化性,如低聚糖等,能够选择性促进益生菌的生长。基于益生菌和益生元对人体健康的重要意义,本文简要讨论了今后开发前景。

The most typical active components of probiotic are lactic acid bacteria, including bifidobacteria, lactobacilli etc, it enhanced maintenance of nornmal/ healthy intestinal flora and protection against infections, alleviation of lactose intolerance, and stimulation of the immune system. Probiotics were consiedred beneficial, and may be stimulated by non-digestible food ingredients such as oligosaccharides, collectively called prebiotic. The developmint prospect of probi-otics and prebiotics were studied in this paper.
