Shiitake mushrooms are rich in the trace element selenium. Many observational studies and cellular experiments have found that selenium has a preventive effect against lung cancer, and there is a correlation between higher plasma levels of selenium and prolonged survival in lung cancer patients. In addition, shiitake mushrooms contain high levels of β-glucan, which can promote lung cancer cell death in lung cancer cell experiments by reducing lung cancer cell activity and decreasing processes such as lipid peroxidation.
Lung cancer patients can eat more shiitake mushrooms as appropriate. 4-5 shiitake mushrooms per day can meet half of the body’s intake of selenium.
