The bestselling author of the Wheat Belly books brings his next big, game-changing idea--how the human microbiome is evolving, and potentially wrecking, our health, and how we can fix it. Because of our highly processed diet, pesticides, and overuse of antibiotics, our guts are now missing so many of the good bacteria that we require to be healthy. As a result, many of us have lost control over our health, weight, mood, and even behavior. The ancient bacteria that keep our digestion moving have been dying, replaced by harmful microbes that don't keep us physically and mentally fit. With cutting-edge research, Dr. Davis connects the dots between gut health and modern ailments. There are entire species of microbes that have disappeared, which creates health issues that were uncommon one hundred, or even fifty, years ago. The result is SIBO (small intestinal bacterial overgrowth), a silent and profound epidemic, which affects one out of three people and is responsible for an astounding range of human health conditions. Super Gut shows us how to eliminate bad bacteria and bring back the "good" bacteria with a four-week plan to reprogram your microbiome. This not only gets to the root of many diseases, but also improves levels of oxytocin (the bonding/happy hormone), brain health, anti-aging, weight loss, mental clarity, and restful sleep. Also included are more than forty recipes, a diet plan, and resources so you can pinpoint your gut issues, correct them, and maintain your long-term health and well-being.
