[The global challenge of the XXI century - COVID-19: the answer of dietetics].

For the first time, the world is facing a global threat to humanity and unprecedented challenges associated with the spread of COVID-19. The fight against the new coronavirus infection requires the joint efforts of the entire world community and equal cooperation. The entire healthcare system is working today in a mobilization format. During the ongoing pandemic, the issue of nutrition of the population remains relevant. Increasing the adaptive potential of the body by optimizing nutrition is a necessity.

[COVID-19: new challenges for medical science and practical health].

Currently, due to the wide spread of the new coronavirus infection COVID-19 and the need for anti-epidemic measures, medical science should integrate all efforts to ensure, on the one hand, at the global level - the fight against the spread of infection, on the other hand, at the individual level - increasing the adaptive capacity and immune response of the organism to protect against COVID-19. Nutrition is the most important factor determining human health and the functioning of all mechanisms to protect a person from negative environmental factors. For the prevention and treatment of new coronavirus infection COVID-19, a significant role is played by the correction of eating disorders, including vitamin and micronutrient deficiency. Federal Research Centre of Nutrition and Biotechnology, together with Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing (Rospotrebnadzor), prepared Recommendations on nutrition for children and adults, requiring a self-isolation regime or quarantine at home in connection with COVID-19. In order to promptly inform and advise the population on nutrition optimization in the early days of anti-epidemic measures, an information reference Contact Center was created and is continuously functioning on the basis of the Federal Research Centre of Nutrition and Biotechnology. Equally important is the implementation of measures aimed at the prevention of food contamination with COVID-19 agent. In this regard, the Federal Research Centre of Nutrition and Biotechnology, together with Rospotrebnadzor prepared guidelines on measures to prevent the transmission of a new coronavirus infection through foods. Another aspect that the medical community has faced in connection with the pandemic is the need to reorient specialized medical organizations that have not previously worked with patients with infectious diseases in order to create Clinical centers for the treatment of the new coronavirus infection COVID-19. Thus, in the context of the spread of the new coronavirus infection COVID-19, many areas of medicine are involved in the process of providing anti-epidemic measures. Successful completion of the tasks will significantly reduce the negative consequences of the COVID-19 pandemic for the state and citizens.
