Immune-Boosting Foods

The immune system plays an important role in keeping a person healthy. It consists of organs, cells, tissues, and proteins. They work together to ward off pathogens, such as viruses, bacteria, and foreign bodies that can cause infection or disease. A pathogen triggers an immune response when it comes in contact with the immune system. Antibodies produced by the immune system attach to antigens on pathogens and kill them.
