These results add weight to the theory that the gut-brain axis plays a crucial role in mental health. And because diet has a direct bearing on the health and diversity of our gut microbiomes, what we eat matters. Gut microbes feed on the fiber in our diets, so getting plenty of vegetables, leafy greens, fruit, nuts, grains and legumes is important., The Gut-brain axis is a bidirectional neural and humoral signaling that plays an important role in mental disorders and intestinal health and connects them as well., From mood and behavior to memory and emotional resilience, your gut can shape your mind in ways most people never imagined. In this article, we’ll explore the fascinating link between gut health and mental health, how your digestive system communicates with your brain, and what you can do to nurture both., The gut-brain axis, a complex communication network between the gastrointestinal tract and the central nervous system, is now recognized as playing a crucial role in mental health., The gut-brain axis is a two-way communication system between the gut and the brain, involving nerves, hormones, and gut microbes. The gut microbiome, consisting of trillions of bacteria, plays a crucial role in mental health by producing neurotransmitters like serotonin and GABA., Functional MRI studies show that stress and anxiety alter gut motility and change how gut microbes behave—tightening the feedback loop between emotional distress and bowel dysfunction. The leaky gut allows harmful substances to enter the bloodstream, contributing to brain inflammation..
