Effects of the Human Gut Microbiota on Cognitive Performance, Brain Structure and Function: A Narrative Review

This narrative review highlights the connection between the human gut microbiota and brain function, emphasizing their role in cognitive performance and emotional regulation. Studies show that diverse gut microbiota support cognitive flexibility, memory, and executive function. Interventions like probiotics and prebiotics can positively influence gut-brain communication, improving memory and attentional performance. While promising, the field requires further research to solidify findings and establish practical recommendations for enhancing cognition.

Include probiotic and prebiotic-rich foods, like yogurt, fermented vegetables, and fiber-rich fruits, in your diet to support gut and brain health. Consistency over weeks can lead to cognitive benefits. However, individual responses may vary, and more rigorous evidence is needed to determine the most effective interventions.
