7 Immune-Boosting Foods For Seniors

The immune system is a complex network of cells and organs that protect the body from infection. The first line of defense is the skin, which acts as a barrier to keep out harmful bacteria and viruses. If these invaders get past the skin, they are met by the second line of defense: the immune cells. These cells constantly look for anything that doesn’t belong in the body, and when they find it, they fight back. The immune cells work together with the other parts of the body, such as the lymph nodes and spleen, to rid the body of infection.

With such a complex and vital system, it’s no wonder that your immune system needs a little help from time to time. A healthy diet is often the key to keeping your immune system strong, so here’s a list of immune boosting foods that can help your body keep infection at bay.
