There’s a community of 38 trillion microorganisms living in and on our bodies, and most of them reside in our gut. That’s equal to the number of cells in the human body. By this definition, we are only 50% human. This is why gut health has such a huge impact on human health, and research in this area is exploding. What does the science say about the intersection between the gut microbiome and autoimmune health? Where can we apply that knowledge in our own lives? And what are some common myths and misconceptions that new research is starting to dispel? My guest today is Dr. Lucy Mailing, a research scientist specializing in how diet and lifestyle impact the gut microbiome in both health and disease states.
