Meta-Analysis Shows Green Tea Reduces Risk of
Breast Cancer
Study background: This study is a meta-analysis,
which means it's a "marriage" of previously-conducted studies and
their statistical results, producing a single, large study that carries more
scientific weight than any of the individual studies alone. In this case, 4
different epidemiologic (population) studies were statistically combined.
Type of study: Meta-analysis
What happened: The combined results of four studies
showed a reduced risk of breast cancer in those drinking the most
green tea, versus those drinking the least. Specifically, those drinking
the most green tea were 12% less likely to develop breast cancer.
Researchers' conclusion: "The results of this
meta-analysis indicate a lower risk for breast cancer with green tea
consumption."
