饮食与肠道菌群关系的研究进展

人体肠道内含有大量的微生物,直接参与了机体的各种代谢活动,与人体健康密切相关。研究显示肠道菌群的构成和稳定受到诸多宿主和环境因素的影响,其中饮食因素起着至关重要的作用。特别是西方高脂饮食方式造成肠道菌群结构改变,从而导致一些慢性、非传染性和免疫相关性疾病的发生。在过去的几十年中,肠道菌群在人体健康中的作用越来越受到关注。不同饮食结构可以对肠道菌群的组成和多样性产生重要的影响。在这篇综述中,我们总结了肠道微生物与人体健康之间的关系以及益生菌在饮食中的作用,为指导和建立健康饮食结构提供理论指导,为相应疾病的防治提供参考。

Advances in research on relationship between diet and gut microbiota

The human intestinal tract contains a large number of microorganisms which are directly involved in various metabolic activities of the body and closely related to human health. Studies have shown that the composition and stability of gut microbiota are influenced by many factors from host and environment, among which dietary factors play a crucial role. In particular, the high|fat diet in Western food has led to changes in the structure of intestinal flora, resulting in some chronic, non|communicable and immune|related diseases. In the past few decades, the role of gut microbiota in human health has received increasing attention. Different diets can have important effects on the composition and diversity of gut microbiota. In this review, we summarized the relationship among intestinal microorganisms, human health and the role of probiotics in diet, for the purpose of providing theoretical guidance for establishing a healthy diet structure, and providing reference for the prevention and treatment of corresponding diseases.
