Consumption of Fresh and Dried Mushrooms and Green Tea May

Significantly Lower Risk of Breast Cancer

Reference: " Dietary intakes of mushrooms and green tea combine to

reduce the risk of breast cancer in Chinese women, " Zhang M, Holman CD,

et al, Int J Cancer, 2008 Oct 1; [Epub ahead of print]. (Address: School

of Population Health, The University of Western Australia, 35 Stirling

Highway, Crawley, Perth, WA 6009, Australia).

Summary: In a case-control study involving 1,009 women aged 20-87

years, with breast cancer, and 1,009 healthy age-matched controls,

results indicate that dietary intake of mushrooms and green tea may

lower the risk of breast cancer. Diet information was gathered using a

validated questionnaire. Daily intakes of >/= 10 g fresh mushrooms and

>/= 4 g dried mushrooms were associated with 64% and 47% reduced risks

of breast cancer, respectively, compared with no intake of mushrooms.

Additionally, women with high intakes of fresh and dried mushrooms who

consumed green tea daily (beverages made from >/= 1.05 g dried green tea

leaves per day) showed 89% and 82% reduced risks of breast cancer,

compared with women who did not consume mushrooms or green tea. Thus,

the authors conclude, " …higher dietary intake of mushrooms decreased

breast cancer risk in pre- and postmenopausal Chinese women and an

additional decreased risk of breast cancer from joint effect of

mushrooms and green tea was observed. More research is warranted to

examine the effects of dietary mushrooms and mechanism of joint effects

of phytochemicals on breast cancer. "
