What if the key to better digestive health isn't simply eliminating more foods but understanding what's happening beneath the surface?
In this episode, I'm joined by James Marin, RD, EN, an Integrative Registered Dietitian, Environmental Nutritionist, and co-founder of the Good Gut SIBO/IBS Program and Married to Health.
James is known for taking a systems-based approach to health, looking beyond symptoms to identify the root causes of digestive issues. In this conversation, we explore the gut microbiome, fibre, IBS, SIBO, histamine intolerance, and a plant-based approach to supporting gut health. We also discuss what happens to the gut when we don't consume enough fibre, whether beneficial gut bacteria can recover after years of a low-fibre diet, and why taking a whole-person approach is often more effective than simply chasing symptoms.
Whether you're struggling with digestive issues, interested in optimizing your gut health, or want to better understand the science behind the microbiome, this episode is packed with practical insights and evidence-based information.
In this episode, we discuss:
• The importance of dietary fibre for gut and overall health
• What happens to the gut microbiome on a long-term low-fibre diet
• How gut bacteria support the intestinal barrier
• SIBO and IBS: causes, misconceptions, and treatment approaches
• Histamine intolerance and MCAS
• Looking beyond food when investigating digestive symptoms
