The coronavirus disease 2019 (COVID-19) pandemic has put focus on the importance of a healthy immune system for recovery from infection and effective response to vaccination. Several nutrients have been under attention because their nutritional statuses showed associations with the incidence or severity of COVID-19 or because they affect several aspects of immune function. Nutritional status, immune function, and viral infection are closely interrelated. Undernutrition impairs immune function, which can lead to increased susceptibility to viral infection, while viral infection itself can result in changes in nutritional status. Here, we review the roles of vitamins A, C, D, and E, and zinc, iron, and selenium in immune function and viral infection and their relevance to COVID-19.
2019年冠状病毒病（COVID-19）大流行使人们关注健康免疫系统对于从感染中康复以及对疫苗接种做出有效反应的重要性。几种营养素受到关注，因为它们的营养状况与COVID-19的发病率或严重程度相关，或者因为它们影响免疫功能的多个方面。营养状况、免疫功能和病毒感染密切相关。营养不良会损害免疫功能，这可能导致对病毒感染的易感性增加，而病毒感染本身会导致营养状况的变化。在此，我们综述维生素A、C、D和E，以及锌、铁和硒在免疫功能和病毒感染中的作用及其与COVID-19的相关性。
