Defense against Coronavirus

When any virus invades the human body, it tries to attach itself to the host cells and take over them. In response to this action of the viruses, the human body produces antibodies, which are proteins that recognize and removes viruses. This is how the immune system in our body keeps protecting us from various harmful pathogens like viruses, disease-causing microbes, and other foreign anti-bodies.

There are certain foods that are very helpful in boosting the immune system of the body and prevent us from the impacts of numerous disease-causing pathogens like viruses, bacteria, and microbes.
