The gut-brain axis is a crucial connection between diet and mental health, influencing emotional regulation and cognitive function. The gut microbiome produces neurotransmitters, like serotonin, that affect mood and behavior. A diet rich in probiotics, fiber, and omega-3 fatty acids can positively impact gut health, thereby supporting mental well-being. Conversely, a poor diet may disrupt gut microbiota, potentially leading to increased feelings of anxiety and depression, underlining the importance of a balanced, nutrient-rich diet for overall mental health.
