Summary The human body hosts enormous diversity of microbiota. Recently, the importance of microbial communities to host physiology has been recognised. Evidence is now emerging that the bidirectional communication between the central nervous system and gastrointestinal tract may affect human nerves, cognition and behaviour through the gut‐brain axis (GBA). Although the connection between enteropathy and neurological diseases has been found, it now seems intestinal microorganisms represent the direct mediator of psychopathology. The interactions between host neurological function and intestinal microbiota suggested dietary is a possible way to alleviate psychopathological and neurodegenerative diseases. This review discusses the possible effect of intestinal microbiota on the changes of nerves and emotions in human brain. Maintaining healthy diet strategies should be an important part of preventing neurological diseases and psychopathologies caused by systemic metabolic changes. We hope to provide a novel insight for the design of dietary therapies from the perspective of GBA.
