The Second Brain in Your Gut: The Shocking Truth About Your Mental Health | Explanation Your gut isn’t just about digestion — it’s home to your “second brain.” Inside your stomach lies a powerful network called the enteric nervous system, directly connected to your brain through the gut–brain axis. In this eye-opening video, Dr. Jane reveals the shocking truth about how your gut health controls your mood, anxiety, depression, and overall mental well-being. 5 Important Facts: The gut contains over 100 million nerve cells, often called the “second brain.” About 90% of serotonin, the happiness chemical, is produced in the gut. An unhealthy gut microbiome is linked to depression, anxiety, and mood disorders. Processed foods and stress disrupt gut bacteria, affecting mental health. A balanced diet rich in fiber and probiotics can improve both gut and brain function.
