With "The Secret of Water," the first "water book" is now available that comprehensively addresses all aspects of the chemical compound H2O. With "The Secret of Water," Peter Jäger attempts to comprehensively present water in all its aspects as a food, medicine, and pleasure.

Water, our "number one food," is so commonplace that we often no longer consciously perceive its presence and effectiveness.
The author's professional career alone (including Weihenstephan and the Austrian Beverage Institute) ensures that the content of the book goes far beyond general phrases such as "Water is life." On the contrary, this book is a non-fiction book that delves deeply into the subject of water.
The chapters range from water analyses and legal regulations on water quality to the role of water as a foodstuff, the contribution of water to health and disease, the water quality of rivers and lakes and the possibilities of water treatment.
All German, Austrian, and Swiss mineral waters are analyzed with regard to their health effects. This, along with the discussion of topics such as the nitrate content of the water or the advantages of glass or plastic bottles, makes the book a useful guide for everyone who has anything to do with water—that is, for each and every one of us.
A detour into areas that have not yet been explored, such as Marienwasser, Lichtwasser, revitalized or energized water and other (controversial) healing waters, rounds off the book and at the same time provides an answer to why water can be described as a secret even in the title of a well-founded non-fiction book.
