Diet therapy as a component of ancient medicine

Conclusions: Critically summarizing the achievements of medicine in therapy, surgery, and pathology, Celsus consistently emphasized the importance of diet therapy in the treatment and prevention of diseases. As a result of the research, it has been established that even in ancient times, the nutrition of a sick person was considered the fundamental basis upon which other therapeutic measures should be applied. Dietary nutrition was aimed at reducing the risk of complications, restoring the body, and preventing diseases. The main principles of ancient diet therapy were based on the following: aligning the diet with the physiological needs of the body during illness, adapting food processing methods for specific diseases, determining the duration of the diet depending on the characteristics of the disease's progression, maintaining water balance, and applying principles of adjustment, substitution, and physical or mechanical protection of the affected system or organ.
