Immunonutrition may improve COVID-19 patients' recovery

Researchers duo Emma Derbyshire and Joanne Delange from the Nutritional Insight, Surrey, United Kingdom, explore the role of immunonutrition – nutrition that boosts or influences the immune system for those over 65 years of age in COVID-19. Their study titled, “COVID-19: is there a role for immunonutrition, particularly in the over 65s?,” was released in the latest issue of the BMJ Nutrition, Prevention and Health.
