One study published back in a November 2007 issue of the International Journal of Cancer suggests that diets high in certain flavonoid compounds found in vegetables, fruits, beans and tea may significantly lower a woman's risk of developing ovarian cancer.
Flavonoids are a large family of antioxidant compounds known as phytochemicals. They are part of a plant's natural defense system that helps the plant fight off disease and infection. When consumed as food, these powerful nutrients help the human body to fight disease and infection as well by protecting cells from DNA damage. Scientists also believe that some flavonoids may also fight cancer by regulating cell growth, fighting inflammation or by changing hormone levels.
