Описание
The soybean has been used as a food source for more than 5,000 years. Plant estrogens (phytoestrogens) were first identified in the early 1930s. At that time it was discovered that soybeans, and pomegranates contained compounds that were much like estrogens. Scientists began studying the role isoflavones play in reducing breast cancer risk in the 1960s. In a 1981 prospective study in Japan, researchers found that daily intake of miso,a soybean paste, was linked to lower death rates from stomach cancer in more than 260,000 men and women. Among their many biological activities, the predominant polyphenols in green tea and the theaflavins and thearubigins in black teas have antioxidant activity. Tea Polyphenols have also been shown to inhibit tumor cell proliferation and induce apoptosis in laboratory and animal studies. In other laboratory and animal studies, tea catechins have been shown to inhibit angiogenesis and tumor cell inventiveness.
