With one in four Americans suffering from digestive health issues every day, gut health has become an increasingly important part of wellness. With the human body, so many issues can be improved upon, or cured, by balancing the microbiome. But the microbiome—a community of bacteria, viruses, and yeasts that dwell in the body—has long been something that the average person can find baffling—and maybe a little bit gross. By offering simple and straightforward answers to questions like what one should be eating, what probiotics are, which vitamins and medicines work, Dr. Raj demystifies the gut. She uses the idea of a home renovation to show how different organs and parts of the body can be “renovated” in order to optimize the microbiome. After all, balancing one’s microbiome improves digestive health, brain function, emotional stability, the body’s response to inflammation, immunity, and lessens premature aging. Melding the latest developments and discoveries in microbiome research, along with Dr. Raj’s practical tips developed from her years of clinical experience, shows readers how to turn back the biological clock and revamp the way they live forever.
