Wherever I turn these days, I encounter articles discussing the gut microbiome. This makes sense to me as a functional medicine and integrative medicine clinician. From day one in functional medicine education, we learn: “All disease begins in the gut.” This statement is attributed to Hippocrates, the father of medicine, from around 2,000 years ago. Amazingly, this message still rings true today. When the gut microbiome is disrupted, processes regulated by the gut, such as immunity and brain function, are impaired. This ultimately may lead to the development of chronic conditions such as autoimmune disease, metabolic dysfunction, and mental health issues, among many other health problems.
