Emerging and re-emerging infectious diseases are now occurring at unprecedented speed, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), commonly referred as Covid-19 pandemic. Although the majority of the population is susceptible to Covid-19, there are risk factors that are seen as clinical predictors of hospitalization, disease severity and mortality. Since the poor nutritional status of patients affects the prognosis of Covid-19, the present work was to develop with the aim of presenting a view on the role of nutrition in the treatment of patients with this respiratory infection, at the level of identification of nutritional risk, assessment of nutritional status, nutritional diagnosis, nutritional treatment, monitoring and nutritional evolution. Symptoms and comorbidities reported by patients infected with SARS-CoV-2 may be determining factors in the prognosis of Covid-19. These patients should undergo a nutritional status assessment to identify complications associated with SARS-CoV-2 infection, such as increased energy requirements, malnutrition, involuntary weight loss, gastrointestinal disorders and dehydration. Recognizing these complications will allow establishing the best nutritional therapy to be applied. The inflammatory condition and the characteristic symptoms of this disease lead to an increase in catabolism and, consequently, to an increase in nutritional requirements. This clinical picture is exacerbated by hospitalization, which is why patients recovering from Covid-19 should benefit from follow-up, in order to ensure adequate rehabilitation. Nutritional intervention in patients with Covid-19 is of great importance and, despite the existence of guidelines, each case must be interpreted individually, not focusing only on nutritional therapy.
