Immune Foods for Fighting Coronavirus Disease-2019 (COVID-19)

Nutritional measures and food components such as micronutrients, macronutrients, and food bioactive compounds, boost the immune system to effectively fight COVID-19. Nutrient deficiencies reduce immune functions against COVID-19, while supplementation of specific nutrients improves the immune system against viral disease. Several macronutrients and micronutrients, including bioactive compounds, prebiotics, and probiotics, have been linked to COVID-19 treatment and prevention. Vitamins D, C, A, E, and B vitamins have been linked with improvement and recovery from COVID-19. Several minerals such as zinc, selenium, iron, copper, magnesium, etc. have activities against SARS-CoV-2 and COVID-19. Many studies have shown that bioactive compounds such as resveratrol, astaxanthin, quercetin, docosahexaenoic acid, eicosapentaenoic acid, epigallocatechin-3-gallate, theaflavin, etc., have promising actions against SARS-CoV-2 and COVID-19. Foods and food components should be properly utilized to fight COVID-19 and are valuable in drug discovery against COVID-19.
