Gut health and mood influence each other through a complex relationship often referred to as the gut-brain axis. The gut microbiome produces neurotransmitters like serotonin, which play a significant role in regulating mood and anxiety. A healthy gut can lead to improved mental well-being, while an imbalance in gut bacteria may contribute to mood disorders such as depression or anxiety. Additionally, dietary choices impacting gut health, such as consuming fermented foods, can enhance mental health by fostering a balanced microbiome. Thus, maintaining gut health is vital for emotional and psychological well-being.
