The vagus nerve is the main communication highway between gut and brain controlling digestion, mood, and immunity.
Activating the vagus nerve shifts you from fight-or-flight to rest-and-digest improving nutrient absorption and calm.

Eat Dirt

Why Leaky Gut May Be the Root Cause of Your Health Problems and 5 Surprising Steps to Cure It

Josh Axe

In 'Eat Dirt', Dr. Josh Axe explains the hidden causes and widespread effects of leaky gut syndrome, a condition where microscopic tears in the intestinal walls lead to widespread inflammation and weakened immunity. The book argues that modern 'improvements' to our food supply, such as refrigeration, sanitation, and processed foods, have contributed to this condition. Dr. Axe provides diagnostic quizzes and simple regimes to heal the gut, including reducing antibiotic use, eating seasonally, spending more time outdoors, managing stress, and incorporating probiotic-rich foods into the diet. The book emphasizes the importance of restoring bacterial diversity in the gut to achieve optimal health.

Ever wonder why anxiety, brain fog, or even memory loss often come hand-in-hand with digestive issues?

In this episode, Dr. Josh Axe unpacks the fascinating science of the gut-brain connection, showing how your microbiome and vagus nerve directly shape your mood, focus, and long-term brain health. You’ll also discover the hidden gut disruptors sabotaging your mental clarity—and the foods, herbs, and daily habits that can restore balance, sharpen your mind, and protect against everything from depression to Alzheimer’s.
