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.
