This book does not present one type of diet suitable for athletes, another for businesspeople, another to reverse diseases, another that is more sustainable with the planet in mind or another to promote greater longevity. A holistic approach to nutrition for the 21st century human being must be able to answer all these questions and, simultaneously, promote their mental and spiritual evolution.

Throughout the book, the author highlights the profound interconnection that exists between human beings and the natural world that surrounds us, highlighting the importance of an approach that transcends the dietary models of primitive man, for whom survival was the main concern. In addition to a therapeutic eating regimen, the book also promotes principles of a lifestyle suited to the challenges and complexities of modern life.
