46. How Processed Oils Harm Digestion (and What Ayurveda Says to Do Instead)

Kate O’Donnell welcomes Dr. John Douillard, DC, CAP, a pioneer in Ayurveda and modern health integration. Together, they explore some of the most confusing and most-asked questions in wellness today: Which cooking oils are truly healthy? How do we eat seasonally in a modern world? And how can breathwork provide nourishment as powerful as food itself?

Dr. John shares his personal journey from competitive triathlete to living in India, studying Ayurveda, and eventually creating LifeSpa.com, one of the largest online Ayurvedic resources. He explains why processed oils are so damaging to digestion, how seasonal diets build resilience and metabolic flexibility, and why breathing through the nose can change everything from anxiety to immunity.
