In this episode of the Sober Head Podcast, host Dr. Esra Çavuşoğlu sits down with Dr. Jeffrey Bland, PhD — biochemist, educator, and founder of the Institute for Functional Medicine, often referred to as the father of functional medicine. The conversation centers on a compelling idea: the immune system may be one of the most powerful regulators of how we age.
Dr. Bland walks through why we get sick in the first place, the origins of functional medicine, and how everyday "life signals" shape our biology over time. From there, the discussion moves into immune aging and whether it can actually be measured, the concept of "angry" visceral fat, and the chronic low-grade inflammation now known as inflammaging.
Other key topics include the gut-immune-brain connection, what immune resilience really means, and the surprising links between trauma, immune memory, and psychedelics. Dr. Bland also unpacks CHIP cells and biological aging, the emerging field of immunometabolism, and so-called "dark matter nutrients" — lesser-studied compounds that may play an outsized role in health. Polyphenols and Himalayan Tartary Buckwheat get particular attention as food-based tools for supporting immune function. Perhaps most striking: Dr. Bland shares research that immune aging can be slowed by up to 47% — and reveals that at 80 years old, his own biological age tests at 64.
The episode closes with his top practical advice for longevity. Topics covered: immune aging · chronic inflammation · gut-brain connection · visceral fat · trauma and immune memory · immunometabolism · polyphenols · dark matter nutrients · gene expression and nutrition
