Knowledge is the best protection This essential reading, written by a pioneer in environmental medicine, explains how food, environmental influences, and chemicals burden our bodies. However, we are not helplessly at their mercy, because with certain nutrients and natural body substances, everyone can contribute to protecting their own nervous and immune systems. The foundation of detoxification and nerve protection is the restoration of the gut flora and support of liver metabolism. The significance of this title for our health is explained by Prof. Dr. Dietrich Grönemeyer, who wrote the foreword to this book.
