The Best Superfoods to Increase Immunity 1

Immunity as a concept is vast. The body’s ability to prevent invasion of infection, viruses, and other diseases is immunity. In Ayurveda, immunity is defined as the state of protection from infectious disease. We are exposed to viruses on an everyday basis. One such is COVID-19, which has till now claimed the lives of 2.95 million people worldwide. Coronavirus has made the world realise why having a strong immune system is crucial.

How does the immune system work?

Several interdependent cells are part of our immune system. These cells can fight infections and destroy infection-causing agents. The immune system cells wait for signals from the T helper subset to act against infection-causing germs. Some individuals are gifted with special kinds of genes that equip them with a strong immune system. But all are not that lucky. People who do not have a genetically strong immune system need to increase their immune system’s strength by eating nutritious food, leading an active lifestyle, getting plenty of sun exposure, staying stress-free, and getting enough rest. [1]

In this article, we will learn about immunity and about the various foods to build immunity.
