Proper nutrition can enhance health and lower the risk of coronavirus 2019 (COVID-19), which is caused by coronavirus 2 and causes acute respiratory infections (SARS-CoV-2). Dietitians and other health care providers will benefit from this study, which highlights dietary guidelines. People have been exhorted to eat more fruits, vegetables, and grains in numerous writings. Thirty-one percent of the suggestions focused on the necessity of zinc minerals and vitamins, as well as vitamins C, A, and D, for a strong immune system. COVID-19 reduction is not due to dietary supplementation. It has been proposed as a potential benefit for persons at risk of respiratory infection, as well as those in need of nutrients, in addition to vitamins C and D, zinc, and selenium. While there was no definitive evidence linking food or food packaging to COVID-19 transmission, good food handling and preparation hygiene standards were recommended. There has been no progress in breastfeeding guidelines for women who have been diagnosed with COVID-19. During the COVID-19 epidemic, this study summarizes current research literature and existing guidelines for national and international organizations on healthy eating, vitamin and mineral supplements, and good food hygiene practices. Vendors and health workers will use the results to better cope with dietary guidelines during the COVID-19 epidemic.
