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.
