Cells in the body, known as natural killer cells, respond quickly to “foreign invaders” such as viruses and cancer cells. Their rapid response is essential for the immune system, as it helps the body fight disease.
In the “Journal of Nutrition” in 2007 reported that eating button mushrooms can boost the immune system by increasing the activity of natural killer cells. Scientists believe that this is due to the polysaccharide content of the mushroom which is responsible for its immune-boosting abilities.
