The microbiome device is surprising and its role for human health can hardly be overstated. This is especially true for microorganisms living in our intestines. The well-being of this small "universe" depends on how we feel, how well we fight infections, whether we suffer from chronic diseases and much more. And what, if not food, directly affects the work of the intestines? Here is a book about the microbiome, written by the most famous nutrition specialist in Spain. How does the digestive tract work and how is it connected to other body systems? Why is proper nutrition so important for wellness? What are probiotics for? Blanca Garcia-Orea Aro talks about all this in her fascinating book.
