In this episode of The Mind-Gut Conversation, Dr. Emeran Mayer sits down with Kate Scarlata, RDN, an internationally recognized dietitian, bestselling author, and leading authority on dietary therapies for IBS and chronic digestive disorders.
Drawing from her personal medical journey and decades of clinical experience, Kate offers a deeply insightful and refreshingly nuanced look at some of the most debated topics in gut health today.
Together, they explore the real therapeutic value of the Low FODMAP diet, who it helps, who it doesn’t, and why its success hinges on personalization rather than restriction.
The conversation moves through major controversies in the field, including SIBO over-diagnosis, the confusion around non-celiac gluten sensitivity, the true causes of bloating, and the myth of detox diets.
Throughout, Kate emphasizes a balanced, science-guided, and compassionate approach that prioritizes patient well-being, food enjoyment, and quality of life over dogma.
Key Topics Covered:
• The Low FODMAP diet: benefits, misconceptions, and why personalization matters
• SIBO: over-diagnosis, breath test pitfalls, and when treatment does make sense
• Non-celiac gluten sensitivity: separating nocebo effects from true reactions
• Bloating: dietary vs. physiological vs. stress-related causes
• Why detox culture misses the point—and what the body’s built-in detox systems already do
This is an honest, evidence-informed, and highly practical discussion for anyone navigating digestive symptoms, or for clinicians seeking a more grounded way to help their patients thrive.
