However, doctors world over have to come to the consensus that building a robust immune system will give you a better chance of combating the virus should you contract it. Zinc is one such micronutrient that helps in building immunity and recent studies show that zinc inhibits coronavirus by blocking a key enzyme. Scientific evidence documented in the past few decades shows that consumption of zinc plays a significant role against viral infections including human respiratory infections because of its immuno-nutrient properties.According to a study by the Harvard T.H. Chan School of Public Health- Inadequate zinc intake in India: past, present and future inadequate zinc intake has been rising in India for decades, causing tens of millions of people to become newly deficient in it. Zinc deficiency has caused a malnutrition problem worldwide. The study states that the highest rate of inadequate zinc intake was concentrated mainly in the southern and northeastern states of India with rice-dominated diets: Kerala, Tamil Nadu, Andhra Pradesh, Manipur and Meghalaya. Thus, zinc intake for Indians is of paramount importance.
