Mushrooms Protect Against Breast Cancer

Mushrooms may reduce the risk of breast cancer, according to a case-control study conducted in southeast China. Researchers analyzed dietary records from more than 2,000 pre- and postmenopausal women with breast cancer and a group of matched healthy controls. Intake of fresh mushrooms (greater than or equal to 10 grams per day) and dried mushrooms (greater than or equal to 4 grams per day) decreased risk by 64 percent and 47 percent, respectively. The most commonly eaten mushroom in this study was the white button mushroom; one small white button mushroom weighs 10 grams. An additional protective effect was seen when mushrooms and green tea were both consumed.
