Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused an ongoing global pandemic of coronavirus disease 2019 (COVID-19). Proper nutritional support helps boost the immunity of the human body, strengthen the high-risk populations' defense against SARS-CoV-2, reduce the prevalence of COVID-19, prevent mild cases from developing into severe cases, and reduce the occurrence of adverse symptoms during recovery. Nutritional support is an important guarantee to provide protection against virus infection, promote patient recovery, and improve patient prognosis. Whole nutritional food formulas designed according to the characteristic clinical symptoms of COVID-19 provide patients with comprehensive nutritional support of appropriate nutritional content, which effectively improves the nutritional status of patients and provides strong technical support to improve their quality of survival. During the critical period of COVID-19 prevention and control, more emphasis should be placed on the essential role of nutritional support and the clinical efficacy of nutritional support should be given full play.
