女吃豆腐男吃鱼

 

 

 Women who ate soy regularly as children have a lower risk of breast cancer, American researchers report. And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research.

  据美国研究人员呈文,儿童时代常常吃豆类食物的女性患乳腺癌的风险较小。另外一组研究人员则向美国癌症钻研协会提出,一周吃几回鱼的男性患结肠癌的概率较小。

  The studies add to a growing body of evidence about the role of diet in cancer. Cancer experts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of exercise.

  这两项钻研进一步证实了饮食对于防癌的作用。癌症防治专家以为,在全部种类的癌症中,多达三分之二都是由抽烟、节食及缺少磨炼等生活方式造成的。

  The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 五 to 十一, reduced their risk of developing breast cancer by 58 per cent. It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen- like effects.

  美国天下癌症研究所和夏威夷大学的研究人员发现,在五岁至十一岁时常常吃豆腐、味噌等豆类食物的女性患乳腺癌的概率要低58%。至于豆类食物为何可以防癌还不清楚,无非大豆中所含的名叫异黄酮的化合物拥有雌性激素的作用。

  A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week.

  另外一项钻研评释,一周吃鱼最少五次的男性患结肠癌的风险要比那些一周都吃不到一次鱼的男性低40%。

  Many kinds of fish are rich in omega-三 fatty acids, which interfere with the cyclooxygenase-二 or COX-二 enzyme. COX-二 affects inflammation, which may play a role in tumour growth.

  不少鱼类中所富含的Omega-三脂肪酸可以或许按捺环氧化酶二的活性。环氧化酶二会引发发炎,这可能会刺激肿瘤的生长。
