ABSTRACTSARSCoV2 infection has caused and will continue to cause considerable human suffering. Research on the pathogenesis of viruses has yielded consistent results from various tests of virus entry and spread to the host. These studies also revealed a strong association between harmless inflammations, aging and metabolic disorders, and SARSCoV2 infection and its prognosis. Diet helps regulate inflammation, and nutritious foods can inhibit the entry of viruses. Therefore, we have compiled the literature on antiviral health products that are effective against other similar coronaviruses. The purpose of this study is to comprehensively review the available information about the antiviral activity of nutritious foods and discuss the impact of these findings on the design of diets that can enhance innate immunity and prevent COVID19. This review emphasizes the fundamental impact of nutritious food and diet on inhibiting virus entry, and provides a new perspective for the prevention and treatment of COVID19.
