The on-going COVID-19 pandemic is a major shock to the modern day civilization disrupting economy and livelihood throughout the world. It has been estimated that COVID-19 and malnutrition go hand-in-hand as evidences suggest that undernutrition may make populations more susceptible to COVID-19.

On the other hand, the presence of obesity and other non-communicable diseases as co-morbidities have been linked to more severe and adverse outcomes in COVID-19 patients. However, in the absence of targeted medicinal therapy, immunity is said to be the key player in the fight against COVID-19. Immunity is intrinsically related to nutrition and therefore it is high time to revisit and consider the existing knowledge to hone our tool to combat COVID-19.[1,2,3,4]

The immune system is the body’s line of defense against all the invading agents which may enter our body to produce illnesses. There are different types of immunity – innate, i.e., the one we are born with an adaptive, i.e., the one we acquire throughout life. Also, immunity can be conferred by immunization through vaccines.
