摘要
目的:研究低聚果糖对人体肠道菌群的影响。方法:将100名受试者随机分成试食组和空白对照组,试食组每天服用低聚果糖20 ml,连续14 d,比较两组肠道菌群的变化情况。结果:试食组试验后肠道中双歧杆菌和乳杆菌的数量明显增加,差异均有统计学意义(P<0.01);肠杆菌、肠球菌、拟杆菌、产气荚膜梭菌数量变化差异均无统计学意义(P>0.05)。结论:低聚果糖具有调节人体肠道菌群,增殖双歧杆菌和乳杆菌的作用,且对受试者身体健康无不良影响。
Objective： To study the effect of fructo-oligosaccharide （FOS） on the intestinal flora. Methods： 100 volunteers were divided into test group and blank control group. The test group were given 20mL FOS for 14 days, the changes of intestinal flora were compared between two groups. Results： There were extremely significant increase in the numbers of Bifidobacteria and Lactobacilli （P〈0. 01）, no significant differences in the numbers of Escherichia, Enterococcus, Bacteroides, and C. perfringens （P〉0. 05）. Conclusions： FOS could adjust hurnam intestinal flora, promot the growth of Bifidobacteria and Lactobacilli, have no harmful effects on one＇s health.
