Mushrooms, green tea reduce chance of breast cancer by factor of 10
Women who regularly eat mushrooms, shiitake or other fungi, and drink a couple of cups of green tea every day, are at least ten times more likely not to develop breast cancer than women who don't eat many mushrooms and hardly ever drink green tea. Epidemiologists at the University of Western Australia write about this in the International Journal of Cancer.
Mushrooms & cancer
When it comes to epidemiology, however, indications of the protective effect of mushrooms are few and far between, except for a few Korean studies. One recent Korean study has shown that women who eat more than 12 g mushrooms every day are three times more likely not to develop breast cancer than women who only consume 3 g mushrooms every day. [Nutr Cancer. 2010;62(4):476-83.]
By the way, the most popular mushrooms in the Korean diet are the oyster mushroom [Pleurotus ostreatus], the shiitake [Lentinula edodes] and the ordinary mushroom [Agaricus bisporus]. According to the Korean studies, these reduce the chance of hormone-sensitive breast cancer in particular.
Study
Results
The mushrooms the women ate most in this study were ordinary mushrooms, which they ate fried.
Green tea plus mushrooms
Women who ate 10 g mushrooms or more every day and also drank tea brewed from at least 2 g green tea leaves were almost ten times less likely to develop breast cancer during their lifetime than women who drank little green tea and ate few mushrooms.
A large cup of green tea, about 250 ml, requires about 4 g of tea leaves. It's worth noting that many Chinese top up a cup of green tea with more water several times without adding new leaves.
