绿茶富含多酚,可有助妇女预防乳腺癌。研究者发现大鼠喂食绿茶后可使人工种植的乳腺癌肿块缩小,而仅仅饮用普通水的大鼠则没有该种变化。而且喂食绿茶后一般发生肿瘤时间较迟,侵犯性也小。尽管该实验尚限于动物模式,但提示绿茶可以保护环境致癌物诱致的乳腺癌肿瘤,以前的研究已经发现常饮用绿茶者乳腺发病较低,而且每天饮用3到5杯绿茶对身体没有任何副作用,所以常饮用绿茶对身体有好处。但是研究者警告说,做过放射或化疗的乳腺癌患者需要饮用大量绿茶前应该取得医生同意。 Green tea rich in polyphenols, can help women prevent breast cancer. The researchers found that rats fed green tea had a shrinkage of artificially implanted breast cancer, whereas those who ate only plain water did not. And generally after the feeding of green tea tumor time later, invasive is also small. Although the experiment is still limited to animal models, it suggests that green tea can protect breast cancers caused by environmental carcinogens. Previous studies have found that breast cancers are often associated with lower drinking of green tea and that drinking 3-5 cups of green tea daily has no adverse effect on the body, So often drinking green tea is good for your health. However, researchers warn that patients with breast cancer who have undergone radiotherapy or chemotherapy should seek medical approval before drinking large amounts of green tea.
