Dr. Goyert illustrates how metabolic processes in the human organism can be characterized and what factors, apart from nutrition, play a role in this in the present volume. The processes are integrated into a holistic picture that represents the human being in relation to the world and the spiritual. For more than three decades, the author has been responsible for courses in the training of doctors and curative eurythmists alongside his work as an internist. From this collaborative effort, certainty and assurance have emerged regarding how valuable and enriching anthroposophical anthropology is for understanding metabolic processes in both healthy and sick individuals. Valuable insights are offered not only to medical professionals and therapists but also to readers seeking an expanded understanding in addition to the gastroenterology consultation.
