β-glucans are the main polysaccharides found in mushrooms, with about half of the mushroom cell wall mass made up of β-glucans. Given that β-glucans are not synthesized by humans, they are not recognized by the human immune system. Therefore, upon consumption, they induce both innate and adaptive immune responses as a protective strategy.
In doing so, they protect the body from pathogenic microbes, viruses and harmful environmental toxins and carcinogens that have entered the body. This health-promoting activity can be beneficial for patients with compromised immune systems.
