In this interview, Dr. Jeffrey Bland, the founder of functional medicine, discusses how functional medicine can dramatically improve healthspan by enhancing immune system resilience. He explains that the immune system renews itself roughly every three months, with more than half of its activity centered in the gut, highlighting the importance of gut health. Bland contrasts chronological age with biological age, noting his own example of a 79‑year‑old body with a 62‑year biological age and youthful testosterone levels, attributing this to maximizing genetic potential through functional approaches. He critiques the conventional focus on symptoms, advocating a shift toward understanding and addressing root causes of chronic disease. Specific nutritional recommendations, such as Himalayan tartary buckwheat, are presented as powerful tools for weight loss and disease prevention. Bland also notes the growing institutional acceptance of functional medicine, with the VA and Department of Defense integrating its principles, and references his book The Disease Delusion as a guide to conquering chronic illness. The conversation frames functional medicine as a revolutionary, function‑focused paradigm that can add productive health years to life.

Your chronological age was 79, but your biological age was 62. Your testosterone levels were that of a 30-year-old. What's most contributed to that? It's about how do you maximize the genetic potential that lies within your genome to be the best person you can be. Jeff Bland is the father of functional medicine who turned his own body into a lab for longevity. Joining us now is Dr. Jeffrey Bland, immunity expert and founder. Now joining us, Dr. Jeffrey Bland. He's a world-renowned nutritional medicine expert. I think immunity and the immune system is actually something I've been fascinated by because I don't I don't think actually people understand what it is. It turns out that every minute that we're alive, we're producing about a million new immune cells, which means if you do the math, it means that about every 3 months we've completely reformed our immune system. All these organ systems are interconnected. These are systems that are working 24/7, 365 by cross-communication. They don't just work independently, they're working together. Does it bother you that people ask you all the time, are you retiring? I am retired. And they say, you're retired? I said, yes. I'm re-tiring and putting new tread on my tires so I can roll in the roll of life longer. Coming up on this episode of Heal Squad. Can you think of a drug or procedure that could increase life expectancy by 15.5 years? No. I mean, that sounds like a Nobel Prize-winning thing if you could come up with it. Well, we already have come up with it. If you can functionally improve the resilience of your immune system, you can add productive health years to your life. Doctors are finding it's much more complex than Just getting enough sleep or taking so-called immune-boosting supplements? I think one of the great new discoveries is that if you ask where a lot of the immune system activity occurs in the body, believe it or not, it occurs in our intestinal tract. In fact, more than 50% of our immune system is clustered around our digestive system. What are some of the top foods to eat to lose weight and fight disease? Himalayan tartary buckwheat, a powerhouse Functional medicine comes out of work that we started in the 1990s. It's basically focused on why people get sick rather than what they have. Medical schools are adopting this question, this whole approach. We're seeing the VA and the DOD picking up on this with now veterans approaches. Jeff is the author of The Disease Delusion: Conquering the Causes of Chronic Illness for a Healthier, Longer, and Happier Life. I think that we're in the thresholds of a whole new revolution That is focused on function, not just on downstream pathology. So you can control the outcome of your immune system. That is the lesson of this discussion. Wow. Yes.
