In our discussion today, we examine the gut-immune connection, looking at how inflammation affects the gut microbiome and gut barrier, and how technology and lifestyle impact our health. We discuss the limitations of conventional allopathic medical approaches to disease, the telltale signs that inflammation may underlie your gut-related symptoms, why fiber is the longevity nutrient, and the critical importance of short-chain fatty acids. We also explore the food matrix, changes in perimenopause and menopause regarding fiber intake, the significance of lipopolysaccharides and circadian biology, and how fiber can improve your sleep quality.
