In recent decades there has been a shift from a healthcare concept focused on specific risks and individual protective factors to a patient-oriented or anthropocentric concept of maintaining and improving health. In some areas of medicine, in the presence of a number of diseases of other organs and systems, for example, in the treatment of diabetes, the patient becomes an active participant in the treatment process and must have a very wide range of knowledge and skills to constantly maintain a satisfactory functional state of the organism [1, 2, 3]. But what about those people who do not suffer from chronic diseases? Whatever the answer of specialists, the opinion of society is obvious – the number of sites dedicated to medical, or pseudo-medical, information is incalculable, and reminders about methods of treating the most common chronic diseases are distributed in social networks at lightning speed. Thus, life itself, and not just theoretical research, suggests that preventive measures are the most effective health measures and should be carried out systematically, not pointwise, providing answers to a very wide range of questions [3, 4].
