The million-copy bestseller now updated - with an additional chapter on new scientific findings. Our gut is a marvelous entity full of sensitivity, responsibility, and readiness to perform. When treated well, it shows its gratitude. This benefits everyone: the gut trains two-thirds of our immune system. It provides our body with the energy to live, whether from bread rolls or tofu sausage. It also has the largest nervous system after the brain. Allergies, our weight, and even our emotional world are closely linked to our gut. In this book, young scientist Giulia Enders explains what new insights medical research offers and how we can improve our daily lives with this knowledge. The accompanying illustrations are by her sister Jill. The updated edition is supplemented with a chapter: The Enders sisters give.
