素食如何影响肠道菌群组成
创作:szx 审核:szx 2019年11月10日
  • 纳入36名严格素食者及36名杂食者进行一项横断面研究;
  • 2组受试者的肠道菌群仅在门、科、属、种水平显示出中度差异;
  • 纳入16项研究(包括本项横断面研究)进行系统性综述,进一步分析总结素食/严格素食对肠道菌群组成的影响;
  • 相比于杂食者,未发现素食/严格素食与肠道菌群的一致性关联,一些研究结果甚至互相矛盾;
  • 在研究发现的素食/严格素食与杂食者的肠道菌群组成差异中,拟杆菌属、双歧杆菌属及普氏菌属最常被报道。

Abstract:收起
It is assumed that diet influences the composition of gut microbiota, which in turn may affect human health status. This systematic review aimed to summarize associations of a vegan or vegetarian diet with the composition of microbiota. A literature search was conducted in PubMed and Embase for eligible human studies with vegan or vegetarian diets as an exposure and microbiota composition as an outcome in healthy adults. Furthermore, data from our cross-sectional study with vegan participants were included. Out of sixteen included studies, six investigated the association between gut microbiota composition in both vegans and in vegetarians, six in vegans and four studies in vegetarians compared to omnivores, respectively. Among 5 different phyla, 28 families, 96 genera and 177 species, Bacteroides, Bifidobacterium and Prevotella were the most reported genera, followed by the species Prevotella copri, Faecalibacterium prausnitzii and Escherichia coli in all diets. No consistent association between a vegan diet or vegetarian diet and microbiota composition compared to omnivores could be identified. Moreover, some studies revealed contradictory results. This result could be due to high microbial individuality, and/or differences in the applied approaches. Standardized methods with high taxonomical and functional resolutions are needed to clarify this issue.
