New research suggests that tea, citrus fruits and juices may help stave off the risk of ovarian cancer. Studies show that dietary flavonoids significantly lower the chance of developing epithelial ovarian cancer, the fifth-leading cause of cancer death among women. Researchers say in particular consuming a couple of cups of black tea every day has been associated with a 31% reduction in cancer risk. The main sources of the protective compounds include tea, citrus fruits and juices, as well as red wine, apples and grapes, which are easily incorporated, making them simple yet effective dietary changes.
