Allergies, asthma, obesity, stomachaches, acne: These are just a few of the conditions that may be caused - and cured - by the microscopic life inside us. Understand how to use groundbreaking science to improve your health, mood, and more.

In just the last few years, scientists have shown how the microscopic ecosystems within our bodies - particularly within our intestines - have astonishing impacts on our lives. Pioneering scientist Rob Knight and award-winning science journalist Brendan Buhler explain - with humor and witty metaphors - why these new findings matter to everyone.

You are mostly not you. The human gut is host to trillions of microbes, and evidence shows that small changes in these microbes (altered by antibiotics, diet, geographic region, and so on) may affect weight, likelihood of disease, and even psychological factors like risk-taking behavior. The evidence for their influence is astonishing. Rob Knight is one of the key figures driving forward this new science. His work demonstrates the startling connection between the presence of certain harmless bacteria and the health benefits we all seek - for ourselves and our children.

In Follow Your Gut, Knight pairs with Brendan Buhler, an award-winning science writer, to explore the previously unseen world inside our bodies. With a practical eye toward deeper knowledge and better decisions, they lead a detailed tour of our "microbiome" as well as an exploration of the known effects of antibiotics, probiotics, diet choices, birth method, and access to livestock on our children's lifelong health. Ultimately this pioneering audiobook explains how to learn about your own microbiome and take steps toward understanding and improving your health, using the latest research as a guide.
