据Derrien M 2015年6月1日[Trends Microbiol,2015,23(6):354-366.]报道,来自食物的菌群确实影响着肠道微生物群和宿主健康。从食物进入肠道的很多益生菌确实能够进入小肠,而且躲过了胃里的强酸环境,仍然顽强地或者并还有生理活性,可以完成一些分子的合成代谢。这些微生物占据着正常肠道微生物群体的一部分,并且可很多次在肠道微生物群的分析中被检测出来。肠道微生物群是存在于人体肠道的微生物群体的总称,其中包括了细菌、真菌、古菌及原生物动植物(甚至病毒)等种类众多 According to Derrien M, June 1, 2015 [Trends Microbiol, 2015, 23 (6): 354-366.] It has been reported that flora from food does affect the gut microflora and host health. Many probiotics that enter the gut from the food do enter the small intestine and escaped the acid environment in the stomach and are still stubbornly or physiologically active to complete the synthesis and metabolism of some molecules. These microorganisms occupy a portion of the normal intestinal microflora and can be detected many times in gut microbiota analysis. Gut microbiota is a group of microorganisms that exist in the human intestine, including many kinds of bacteria, fungi, archaea and protozoa (even viruses)
