The key to a happier, healthier life lies within us. Our gut is almost as important as our brain or heart, yet we know very little about how it works. In "Gut," Giulia Enders demonstrates that it is not just a utilitarian and somewhat embarrassing body part, but one of the most complex, vital, and even wondrous parts of our anatomy. Scientists are just beginning to discover how much it has to offer; new research shows that gut bacteria can play a role in everything from obesity and allergies to Alzheimer’s. Starting with her personal experiences with illnesses that inspired her research, and continuing with explanations of everything from the basics of nutrient absorption to the latest science linking gut bacteria to depression, Enders has written an entertaining and informative health book. "Gut" definitely shows that we can all benefit from it.
