The structure of the microbiome is amazing, and its role for human health cannot be overestimated. This is especially true for microorganisms that live in our intestines. The well-being of this little “Universe” determines 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 functioning of the intestines? Here is a book about the microbiome, written by the most famous nutritionist in Spain. How does the digestive tract work and how is it connected to other body systems? Why is proper nutrition so important for good health? What are probiotics for? Blanca Garcia-Orea Haro talks about all this in her fascinating book.
