Here's the truth: the health of your gut (especially the small intestine and its microbiome) affects the health of all organs in the body--and it is often the root of all of your health problems. Your gut is also the epicenter of much or your immune system. If you want to have more resiliency to infection or be less prone to autoimmune disorders--or even cancer--then a healthy digestive system is necessary.
This book will arm you with all of the information you need to determine if you have a leaky gut as well as natural solutions that heal the gut and thus the health of the body. Dr. Stengler's successful healing protocol includes supplements that target specific conditions, healthy lifestyle recommendations such as a stress detox, and delicious prebiotic, probiotic, and Mediterranean recipes chock full of gut-healing foods.
