Green Tea Significantly Reduces Risk of Breast Cancer in Asian-American
Women
Participants: Chinese, Japanese and Filipino
women in Los Angeles County
Type of study: Case-control
Study methods: The health and habits of 501
women with breast cancer were compared to those of 594 women who did not have
the disease.
What happened: After adjusting
for age, menopausal status, body size and other factors, the researchers found
that green tea had a protective effect against breast cancer.
Specifically, women who drank more than 85.7 ml (about
3 oz.) of green tea per day had a 47% lower risk of developing
breast cancer than those who drank no green tea. And those who drank
some green tea, but lesser amounts than 3 oz. per day, had a 29% lower risk.
Researchers' conclusion: "...our results point
to an important role of both green tea and soy intake in relation to breast
cancer risk in Asian-American women."
