Immunonutrition And Corona Virus Disease 2019 (Covid-19)

Abstract

Introduction In late December 2019, severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) initially emerged in Wuhan, Hubei, China, causing the potentially fatal COVID-19. It was then officially declared as a pandemic by the World Health Organization on 11 March 2020. This paper assesses the existing facts concerning to immune-nutrition, with a specific focus on respiratory viruses. In the nutrition segment, a promising body of facts exploring inter-relationships between certain nutrients and immune capability already occurs. This could possibly be crucial in assisting the body to cope with the corona virus, particularly among the elderly. Facts for vitamin C, vitamin D and zinc and their functions in preventing pneumonia and respiratory infections (vitamins C and D) and strengthening immunity (zinc) seems predominantly promising. One recent review recognized that arrange of micro nutrients are essential to meet the complex requirements of the immune system, including vitamins A, D, C, E, B6, B12, folate, copper, iron, zinc and selenium, with numerous of these having likely synergistic associations. Nevertheless, it was reckoned that the major body of evidence linked to immune function occurred for vitamin C, D and zinc [1].
