Now in paperback, evolutionary biologist and science writer Alanna Collen’s stunning alarm call concerning the widely-ignored role our gut microbes play in our health and well-being. “Fascinating…. Everything you wanted to know about microbes but were afraid to ask.”— Kirkus Reviews (starred review) You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them. In this riveting, shocking, and beautifully written book, biologist Alanna Collen draws on the latest scientific research to show how our personal colony of microbes influences our weight, our immune system, our mental health, and even our choice of partner. She argues that so many of our modern diseases—obesity, autism, mental illness, digestive disorders, allergies, autoimmunity afflictions, and even cancer—have their root in our failure to cherish our most fundamental and enduring relationship: that with our personal colony of microbes. The good news is that unlike our human cells, we can change our microbes for the better. Collen’s book is a revelatory and indispensable guide. Life—and your body—will never seem the same again.

“A fascinating, funny, and easy-to-read book about the latest human microbiome discoveries and how these discoveries might help us tend to our inner microbes so as to optimize our overall health.” —Daphne Miller, MD author of Farmacology: Total health from the Ground Up and The Jungle Effect “Virtually every aspect of health and vitality is influenced by the collection of microbes living within us. The Good Gut empowers the reader with the opportunity to embrace this leading edge science in an actionable, user-friendly way.” —David Perlmutter, MD and author, #1 New York Times Bestseller, Grain Brain: The Surprising Truth About Wheat, Carbs, and Sugar: Your Brain's Silent Killers The groundbreaking science behind the surprising source of good health Stanford University’s Justin and Erica Sonnenburg are pioneers in the most exciting and potentially transformative field in the entire realm of human health and wellness, the study of the relationship between our bodies and the trillions of organisms representing thousands of species to which our bodies play host, the microbes that we collectively call the microbiota. The microbiota interacts with our bodies in a number of powerful ways; the Sonnenburgs argue that it determines in no small part whether we’re sick or healthy, fit or obese, sunny or moody. The microbiota has always been with us, and in fact has coevolved with humans, entwining its functions with ours so deeply, the Sonnenburgs show us, humans are really composite organisms having both microbial and human parts. But now, they argue, because of changes to diet, antibiotic over-use, and over-sterilization, our gut microbiota is facing a “mass extinction event,” which is causing our bodies to go haywire, and may be behind the mysterious spike in some of our most troubling modern afflictions, from food allergies to autism, cancer to depression. It doesn’t have to be this way. The Good Gut offers a new plan for health that focuses on how to nourish your microbiota, including recipes and a menu plan. In this groundbreaking work, the Sonnenburgs show how we can keep our microbiota off the endangered species list and how we can strengthen the community that inhabits our gut and thereby improve our own health. The answer is unique for each of us, and it changes as you age. In this important and timely investigation, the Sonnenburgs look at safe alternatives to antibiotics; dietary and lifestyle choices to encourage microbial health; the management of the aging microbiota; and the nourishment of your own individual microbiome. Caring for our gut microbes may be the most important health choice we can make.

Allergies, asthma, obesity, acne: these are just a few of the conditions that may be caused—and someday cured—by the microscopic life inside us. The key is to understand how this groundbreaking science influences your health, mood, and more. In just the last few years, scientists have shown how the microscopic life within our bodies— particularly within our intestines—has an astonishing impact on our lives. Your health, mood, sleep patterns, eating preferences—even your likelihood of getting bitten by mosquitoes—can be traced in part to the tiny creatures that live on and inside of us. In Follow Your Gut, pioneering scientist Rob Knight pairs with award-winning science journalist Brendan Buhler to explain—with good humor and easy-to-grasp examples—why these new findings matter to everyone. They lead a detailed tour of the previously unseen world inside our bodies, calling out the diseases and conditions believed to be most directly impacted by them. With a practical eye toward deeper knowledge and better decisions, they also explore the known effects of antibiotics, probiotics, diet choice and even birth method on our children’s lifelong health. Ultimately, this pioneering book explains how to learn about your own microbiome and take steps toward understanding and improving your health, using the latest research as a guide.

New York Times Bestseller New York Times Notable Book of 2016 • NPR Great Read of 2016 • Named a Best Book of 2016 by The Economist, Smithsonian, NPR's Science Friday, MPR, Minnesota Star Tribune, Kirkus Reviews, Publishers Weekly, The Guardian, Times (London) From Pulitzer Prize winner Ed Yong, a groundbreaking, wondrously informative, and vastly entertaining examination of the most significant revolution in biology since Darwin—a “microbe’s-eye view” of the world that reveals a marvelous, radically reconceived picture of life on earth. Every animal, whether human, squid, or wasp, is home to millions of bacteria and other microbes. Pulitzer Prize-winning author Ed Yong, whose humor is as evident as his erudition, prompts us to look at ourselves and our animal companions in a new light—less as individuals and more as the interconnected, interdependent multitudes we assuredly are. The microbes in our bodies are part of our immune systems and protect us from disease. In the deep oceans, mysterious creatures without mouths or guts depend on microbes for all their energy. Bacteria provide squid with invisibility cloaks, help beetles to bring down forests, and allow worms to cause diseases that afflict millions of people. Many people think of microbes as germs to be eradicated, but those that live with us—the microbiome—build our bodies, protect our health, shape our identities, and grant us incredible abilities. In this astonishing book, Ed Yong takes us on a grand tour through our microbial partners, and introduces us to the scientists on the front lines of discovery. It will change both our view of nature and our sense of where we belong in it.

“In Missing Microbes, Martin Blaser sounds [an] alarm. He patiently and thoroughly builds a compelling case that the threat of antibiotic overuse goes far beyond resistant infections.”—Nature Renowned microbiologist Dr. Martin J. Blaser invites us into the wilds of the human microbiome, where for hundreds of thousands of years bacterial and human cells have existed in a peaceful symbiosis that is responsible for the equilibrium and health of our bodies. Now this invisible Eden is under assault from our overreliance on medical advances including antibiotics and caesarian sections, threatening the extinction of our irreplaceable microbes and leading to severe health consequences. Taking us into the lab to recount his groundbreaking studies, Blaser not only provides elegant support for his theory, he guides us to what we can do to avoid even more catastrophic health problems in the future. “Missing Microbes is science writing at its very best—crisply argued and beautifully written, with stunning insights about the human microbiome and workable solutions to an urgent global crisis.”—David M. Oshinsky, author of the Pulitzer Prize-winning Polio: An American Story

Cutting-edge neuroscience combines with the latest discoveries on the human microbiome to inform this practical guide that proves once and for all the inextricable, biological link between mind and body. We have all experienced the connection between our mind and our gut—the decision we made because it “felt right;” the butterflies in our stomach before a big meeting; the anxious stomach rumbling when we’re stressed out. While the dialogue between the gut and the brain has been recognized by ancient healing traditions, including Aryuvedic and Chinese medicine, Western medicine has failed to appreciate the complexity of how the brain, gut, and more recently, the microbiome—the microorganisms that live inside us—communicate with one another. In The Mind-Gut Connection, Dr. Emeran Mayer, Executive Director of the UCLA Center for Neurobiology of Stress, offers a revolutionary look at this developing science, teaching us how to harness the power of the mind-gut connection to take charge of our health. The Mind-Gut Connection, shows how to keep the communication brain-gut communication clear and balanced to: • Heal the gut by focusing on a plant-based diet • Balance the microbiome by consuming fermented foods and probiotics, fasting, and cutting out sugar and processed foods • Promote weight loss by detoxifying and creating a healthy digestion and maximum nutrient absorption • Boost immunity and prevent the onset of neurological diseases such as Parkinson’s and Alzheimer’s • Generate a happier mindset and reduce fatigue, moodiness, anxiety, and depression • Prevent and heal GI disorders such as leaky gut syndrome; food sensitivities and allergies; and IBS; as well as digestive discomfort such as heartburn and bloating • And much more.
