Our gut microbes perform many different essential functions that help us to stay healthy. In fact, about 90% of all disease can be traced back to the health of the gut and our gut microbiomes. The good news is that our gut bacteria composition is very sensitive to both our short-term choices and long-term habits, particularly when it comes to diet and lifestyle—meaning there’s a metric ton we can do starting today to support a healthy gut microbiome (and therefore a healthy us). With an unprecedented dive into the scientific literature, The Gut Health Guidebook is the culmination of 6 years of research, unveiling 20 essential keys to gut health, the majority of which have yet to permeate any health-conscious community. In this 300+ page e-book, Dr. Sarah builds a new diet for general health, from the ground up, based on the gut microbiome, that merges everything the science currently tells us is healthful into one comprehensive approach.
