By David Liu, PHD

Monday Oct 29, 2012 (foodconsumer.org) --Andy H. Lee at School of Public Health, Curtin University in Perth, WA, Australia ?and colleagues reported a study in Cancer Epidemiology suggesting that drinking tea may cut risk of ovarian cancer.

The researchers compared 500 incident cases of varian cancer with 500 controls, both groups of Chinese women at a mean age of 59 years for tea consumption and found that after adjustment for potential confounders, women who drank green, black and or oolong teas were about 70 percent less likely to be diagnosed with ovarian cancer, compared to those who did not drink.

The subjects for the study were recruited from ?four public hospitals in Guangzhou, China and dietary information on tea drinking was collected through a questionnaire.

The researchers found women without ovarian cancer were found more likely more often to drink more tea than those who were diagnosed with the disease, 78.8% versus 51.4%.

The association between tea drinking and risk of ovarian cancer was affected by the duration of drinking, the number of cups and quantity of tea consumed and the amount of dried tea leaves brewed.

The researchers concluded "Regular tea consumption is associated with a reduced risk of ovarian cancer for southern Chinese women."
