Given that, in recent years, new confusing information about the human microbiome is occasionally disseminated, the book you hold in your hands aims to provide non-experts with a clear picture of this research field.

It deals with a timeless topic, analyzing some of the recent research achievements in the field, in such a way that anyone with a scientific background can understand them.

The book first explains why microorganisms are crucial for our lives and how our diet affects the interaction with the bacteria we host in our gastrointestinal tract. 

It then examines in more detail how microbial communities are organized and why they are able to survive in the very unique environment of our gut. It also explains why a person's microbial "profile" is as unique as their fingerprint, and how this profile can be influenced by the lifestyle an individual follows.

Thanks to its simple and accessible language, this book offers a comprehensive overview for all readers with basic biology knowledge, shedding new light on this fascinating and important part of our body.
