In recent years there has been a renewed interest concerning the ways in which the gastrointestinal tract - its functional integrity and microbial residents - might influence human mood (e.g. depression) and behavioral disorders. Once a hotbed of scientific interest in the early 20th century, this area lay dormant for decades, in part due to its association with the controversial term 'autointoxication'. Here we review contemporary findings related to intestinal permeability, small intestinal bacterial overgrowth, lipopolysaccharide endotoxin (LPS) exposure, D-lactic acid, propionic acid, and discuss their relevance to microbiota and mental health. In addition, we include the context of modern dietary habits as they relate to depression, anxiety and their potential interaction with intestinal microbiota.
近年来,人们重新关注胃肠道(其功能完整性和微生物居民)可能影响人类情绪(例如抑郁)和行为障碍的方式。这个领域在 20 世纪早期曾是科学研究的热点,但在几十年里一直处于休眠状态,部分原因是它与有争议的术语“自体中毒”有关。在这里,我们回顾了与肠道通透性、小肠细菌过度生长、脂多糖内毒素 (LPS) 暴露、D-乳酸、丙酸相关的当代发现,并讨论了它们与微生物组和心理健康的关系。此外,我们还包括了现代饮食习惯与抑郁、焦虑及其与肠道微生物群相互作用的相关内容。
