If a person wants to keep himself healthy, he should try to improve his immune system. The immune system of a human body consists of organs, cells and tissues etc. All of these organs, cells and tissues work together and they fight against viruses and bacteria that can become the cause of different diseases and infections. To kill these viruses and bacteria, our immune system releases antibodies. These antibodies are attached with antigens. Nowadays, if you want to save yourself against the attack of COVID-19, you should strengthen your immune system. The best way to strengthen your immune system is to eat healthy foods. Here, we will discuss the best foods that can make your immune system stronger.
