素食对人类肠道菌群及其代谢产物作用的研究进展

Effects of vegetarian diets on human gut microbiota and metabolites: a review

摘要:

为了探讨素食对肠道微环境的影响及其在维护机体健康中的作用，本文通过文献回顾分析了素食对肠道菌群多样性、潜在有益或有害菌属以及菌群代谢产物的影响。结果发现，素食能够调节肠道微环境，其中纯素、1–2周的短期素食以及某些疾病患者的素食影响更大。而对于肠道特定菌及代谢物，仅有益的普雷沃氏菌(Prevotella spp.)在素食者中显著高于杂食者，其余由于肠道菌群具有一定的个体差异均尚无定论，仍需进一步研究。

Abstract:

To investigate the effects of vegetarian diets on the gut microenvironment and the role in maintaining health, this paper analyzes the effects of vegetarian diets on the diversity, potentially beneficial or harmful genera, and metabolites of gut microbiota by a literature review. Studies have shown that vegetarian diets can modulate the gut microenvironment, with the effects being greater in vegans, those taking short-term vegetarian diets for 1-2 weeks, and the patients with certain diseases. In the gut microbiota, only beneficial Prevotella spp. have significantly higher abundance in vegetarians than in omnivores. The rest taxa are inconclusive due to individual differences in gut microbiota and need further research.
