Man is a particle of Nature, violation of the laws of which leads to diseases. A person, following the path of least resistance, artificially creates bad habits for himself, for example, drinking liquid during and after meals, disrupting all physiological processes occurring in the body. The “garbage bucket” theory (acidification of the body), proposed by the author, explains in the best possible way the cause of diseases, the nature of which does not matter, and how to achieve being healthy. This is discussed in this book.
