Improve Your Immune System With These Foods

We all know that a strong immune system is one of the keys to good health. Yet is it possible that certain types of foods can improve immunity?

The immune system is made up of cells, organs, proteins, and tissues. Together, all of these parts perform bodily functions that ward off bacteria, viruses, and foreign bodies responsible for diseases.

Whenever the immune system encounters a pathogen, it performs an immune response that releases antibodies to the affected area. These antibodies attach to the pathogens and attempts to get rid of them.

Adding specific types of food to your diet could help enhance your immune system.
