“In clinical practice, especially in recent decades, a very wide range of pharmacological agents has been used for therapeutic purposes, which can significantly increase the effectiveness of treatment, especially in the acute phase of the disease and in emergency conditions. Long-term use of drug therapy for chronic diseases with frequent exacerbations is often accompanied by side effects, which significantly reduces the therapeutic effect and sometimes leads to the emergence of new pathological conditions. This circumstance determines the growing interest of specialists in non-drug methods of treatment and prevention of diseases, based on the use of natural factors, essentially eliminating undesirable consequences. This interest is most pronounced in relation to dietary therapy, balanced not only in its main components, but also in essential nutritional factors, adapted to the level and nature of the disorders caused by the disease.”
