The Devil in the Dairy - and Downstream Disease | E27
Dairy’s trusted role in patient diets shifts as Tracy Harrison breaks down how it can drive inflammation, immune reactivity, and persistent symptoms that rarely get linked to food in clinical practice. She explains why lactose intolerance is far more common than most patients realize, how whey and casein can contribute to skin issues, congestion, joint pain, fatigue, and histamine overload, and why some patients tolerate goat or sheep dairy better than cow dairy. Tracy also highlights the problem of hidden dairy in packaged foods and how it can undermine a structured elimination.
This episode gives practitioners a sharper lens for assessing symptoms that look unrelated at first glance and a clearer path for deciding when dairy deserves closer investigation in a patient’s case.

The Most Common Reason Patients Don’t Get Well | E26
Most chronic disease protocols fail because the body won’t heal until it feels safe - and that sense of safety starts with the vagus nerve.
Tracy Harrison takes a closer look at what it really means for the body to be ready to heal. Why do some patients follow every recommendation yet still struggle to make lasting progress? What if the real barrier isn’t what they’re missing, but how their nervous system is responding to the world around them? In this episode, Tracy breaks down how the vagus nerve acts as the body’s communication bridge (regulating inflammation, digestion, fertility, mood, and more) and why chronic stress or unresolved emotions can quietly keep patients in survival mode. She also shares ways to restore vagal tone through simple, accessible habits like diaphragmatic breathing, gratitude, laughter, and restorative rest. These aren’t surface-level stress tips; they’re science-backed tools for helping the body feel safe enough to shift from defense to repair. For practitioners, it’s a call to move beyond managing symptoms and start cultivating an internal environment where healing can actually take root.
Episode Breakdown:
00:00 Why Chronic Disease Persists
01:26 Safety as the Foundation for Healing
05:47 The Vagus Nerve and Whole-Body Regulation

The Secret to Making Functional Medicine Sustainable? | E25
Functional medicine can only create real change when practitioners move beyond collecting information and start developing the confidence, efficiency, and teamwork that bring healing to life.
Tracy Harrison invites practitioners to think honestly about what it means to do this work well. How do you turn deep scientific knowledge into practical, lasting results for real people? How do you keep your passion alive without running yourself into the ground? Tracy explores what it looks like to move functional medicine from a niche movement into a more accessible, sustainable model of care - one that supports both the patient and the practitioner.
Tracy also takes an unfiltered look at the burnout so many practitioners face and why so many feel they have to do everything alone. She shares how collaboration, whether through hiring early, building a multimodality team, or integrating health coaches and pharmacists, can create more impact with less exhaustion. Along the way, she points out the power of group visits, shared education, and patient partnerships that make functional medicine more affordable and effective for everyone involved.
This episode is an honest, encouraging look at how practitioners can move past self-doubt and build a practice rooted in confidence, clarity, and genuine connection.

What’s Really Holding You Back? Hidden Beliefs Sabotaging Your Clinical Impact | E24
Limiting beliefs have a way of sneaking into the work of functional medicine practitioners and Tracy Harrison is pulling them into the light. Have you ever felt like you had to do everything on your own to be credible, or that you should wait until you know absolutely everything before you start? Tracy makes the case for why those assumptions hold you back and how confidence is built through real practice, not endless preparation.
Tracy also looks closely at the practitioner-patient relationship and asks a hard question: what happens when we carry the weight of “fixing” our patients instead of helping them take ownership of their own choices? From moving past overreliance on labs and supplements to creating a true partnership based on education, accountability, and community, she shares a more sustainable way forward.
How much impact could you have if you let go of old assumptions and focused on wisdom, collaboration, and practical action? This episode is a reminder that the future of functional medicine depends on practitioners who are willing to rethink, adapt, and lead with both insight and courage.
Episode Breakdown:
00:00 Truth Telling on Limiting Beliefs in Functional Medicine
02:15 The Myth of Practicing Functional Medicine Alone

Food Sensitivities: Myths and Truths for Practitioners | E23
Food sensitivities often play a bigger role in chronic health problems than many practitioners realize.
In this episode, Tracy Harrison unpacks how foods that look perfectly healthy on the surface can still trigger immune responses that drive inflammation and dysfunction. She explains the differences between IgG and IgA mediated reactions, explores why intestinal permeability matters, and points out the impact of common medications, toxins, and microbial imbalances on immune tolerance.
How often do we assume patients without gut complaints can’t have food sensitivities? What if the clues show up instead as joint pain, skin issues, or fatigue? Tracy also talks through the limitations of food sensitivity testing and why context is everything when interpreting results.
Practitioners will walk away with a clearer sense of why most food sensitivities are acquired, how they can be reversed by addressing upstream dysfunction, and what it looks like to guide patients through elimination, reintroduction, and restoration of tolerance in a way that sticks.
Episode Breakdown:
00:00 Introduction to Food Sensitivities in Functional Medicine
02:07 Myth: Food Sensitivities Don’t Exist
03:02 Food Sensitivities vs. Allergies Explained
07:00 Limitations of Food Sensitivity Testing
