  1. The Oral Microbiome: The Hidden Biomarker Driving Aging, Fertility & Systemic Inflammation

    DEC 16

    The Oral Microbiome: The Hidden Biomarker Driving Aging, Fertility & Systemic Inflammation

    Functional dentistry is emerging as a powerful missing link in systems-based care. In this episode of New Frontiers in Functional Medicine, Dr. Kara Fitzgerald sits down with Staci Whitman, DMD, IFMCP, a leading voice in functional pediatric dentistry and co-founder of the upcoming Institute for Functional Dentistry. Together, they explore how the oral microbiome, airway health, saliva, hormones, nutrition, and stress physiology shape systemic inflammation, chronic disease risk, and long-term health outcomes. You’ll learn how to recognize oral contributors to gut issues, autoimmunity, cardiometabolic disease, cognitive decline, sleep disorders, and more—plus practical tools you can use right away in a medical setting, including a simple five-question airway and breathing screener. If you’re looking to expand your longevity and whole-body health framework, this conversation offers clear, actionable insights you won’t want to miss. Full show notes + references: https://www.drkarafitzgerald.com/fxmed-podcast/ GUEST DETAILS Dr. Staci Whitman is a board-certified pediatric and functional dentist and co-founder of the Institute for Functional Dentistry (IFD). She integrates the oral microbiome, airway and sleep health, nutrition, hormones, and early childhood development into modern dental care.

    The Hidden Immune Signal Accelerating Aging & the Beta-Glucan That Fixes It

    Beta-glucans might be one of the most overlooked levers in immune resilience, and that has major implications for longevity. Talking with my long-time friends and colleagues Drs. Bob Rountree and Chris D’Adamo reminded me just how powerful this molecule truly is. The clinical reach here is stunning, from immune aging and cancer support to vaccine response, gut–brain effects, and overall resilience. What struck me most is how beta-glucans help the innate immune system respond more effectively over time, from overtraining and chronic infections to vaccine responsiveness. Clinicians really need this on their radar. I think you’re going to find this conversation eye-opening. ~DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for the full list of links and resources. GUEST DETAILS Bob Rountree, MD, is a leading figure in integrative and functional medicine with more than 40 years of clinical experience.

    The Bile Acid Imbalance Accelerating Aging: How to Detect ​& Fix It

    Have you ever struggled to understand why some patients just don’t respond as expected, even when you’re following all the usual gut protocols? In this episode, I sat down with Dr. Tom Fabian, who breaks down the latest insights from StoolOMX and GI-MAP testing and shows us how to put them into practice for our most complex cases. We dive into how identifying specific types of inflammation, bile acid patterns, and microbial imbalances can guide more precise interventions, whether it’s introducing fiber, addressing biofilms, or supporting secondary bile acid production. Dr. Fabian makes the science practical, helping us see not just what’s happening in the gut, but what to do about it in real-world clinical settings. ~DrKF FOLLOW ALONG WITH THE CONVERSATION!
