Mushrooms and Cancer Risk?
Eating fresh mushrooms (greater than or equal to 10 grams per day) and dried mushrooms (greater than or equal to four grams per day) may decrease your cancer risk by 64% and 47%, respectively. The most commonly consumed 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 on a daily basis.
