Immunological Insight in COVID-19

COVID-19, the most infectious pandemic disease arose due to SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) and has caused wide health issues globally. As long as the immune system is functioning normally, infections go unnoticed. Therefore, the coronavirus could threaten the immune system in several ways. Without a question, adequate nutrition plays a significant role in preserving health. Significant immunomodulatory effects are produced by micronutrients such as vitamin C, D, and E, zinc, selenite, and probiotics, which are helpful in infectious diseases. Moreover, it has been demonstrated that a few of these nutrients may be useful in the treatment of COVID-19. This review presents a brief overview of the immune system regarding its protection of the body from COVID-19. Immunity can be acquired through the daily staple meals by the use of plenty of minerals, micro-nutrients, and foods rich in vitamins. Indians can exclusively rely on traditional foods as immunity elevators such as spices, citrus fruits, some vegetables, honey etc. Therefore, this review article summarises possible practices of diet and the benefits of minerals, micro-nutrients and vitamins based on relevant literature available in the Pub Med, and Google Scholar. In the instance of COVID-19, it tries to emphasise the significance of nutrition during times of weakened immunity.
