According to Dr. Jeffrey Bland, the “father of Functional Medicine,” the immune system is nature's greatest protector and innovator. It represents your body’s ability to resist all the things that want to tear you apart — and in doing so it intimately defines what is you and what is not you. In this episode, Dr. Bland and Jeff discuss what degrades our immune system as well as how to rejuvenate it.
