The Gut-Brain Axis: How Your Microbiome Controls Mood, Anxiety & Mental Clarity
Introduction For decades, mental health was viewed almost entirely as a brain issue. But emerging neuroscience reveals something fascinating: your gut may influence your mood as much as your brain does. Scientists now refer to this connection as the gut-brain axis — a complex communication network linking your digestive system and central nervous system. If you’ve ever experienced “butterflies in your stomach” during anxiety, you’ve already felt this connection in action. But research shows it goes much deeper. What Is the Gut-Brain Axis? The gut-brain axis is a bi-directional communication system between: The central nervous system (brain & spinal cord) The enteric nervous system (your gut’s nervous system) The vagus nerve Gut microbiota (trillions of bacteria in your digestive tract) According to research published in Nature Reviews Gastroenterology & Hepatology (2019), gut microbes influence: Stress response Inflammation Neurotransmi...
