Regulation of the gut microbiota by diet and exercise: Improvements in cognition and emotion

The intestinal flora lives in the human intestine, and affects the health of the host through the protection of the intestine and its participation in the regulation of the body's metabolism. Gut microbiota plays a key role in regulating psychological behavior by regulating the integrity of the intestinal barrier, significantly alleviating depression, aversion, and anxiety-like emotions, while also regulating and improving human cognition and emotion. It has been proven that the right intake of probiotics and moderate exercise can maintain the homeostasis of the intestinal microbiota, and effectively regulate the composition and structure of the intestinal flora, thus having a positive effect on the regulation of human cognition and emotion. This review discusses the relationship between gut microbiota and health, and further explores the mechanism of maintaining gut microbiota homeostasis through diet and exercise to improve cognitive ability and emotion.
