EATING TOFU ONCE PER WEEK LINKED TO 18 PERCENT DROP IN HEART DISEASE RISK
每周吃一次豆腐可使心脏病风险下降18%
The study from Harvard Medical School and Brigham and Women’s Hospital found a strong association between consuming plant foods rich in isoflavones and reduced heart disease risk.

Eating tofu and other plant foods that are rich in isoflavones could lower a person’s risk of heart disease, according to new research from Harvard Medical School and Brigham and Women’s Hospital in Boston, MA. The study analyzed data gathered from more than 200,000 participants who were all initially free of cancer and heart disease. The participants were asked to complete surveys about their diet every two to four years and their medical data was collected from medical records.
根据美国马萨诸塞州波士顿市哈佛医学院和布莱根妇女医院的新研究结果，食用豆腐及其它富含异黄酮的植物食品可以降低个人患心脏病的风险。该项研究分析了收集得到的200,000多名研究对象的数据；所有这些人员在研究开始时均没有癌症和心脏病。这些研究对象每隔两到四年都需要填写关于个人饮食的调查问卷，而他们的医疗数据则通过查看医疗记录来获得。
The findings showed that after taking into account factors that potentially increase heart disease risk, eating tofu more than once a week was associated with an 18 percent lower risk of heart disease, compared to a 12 percent lower risk for those who ate tofu less than once a month. This link was found to be stronger among the young female participants and in postmenopausal women who were not taking hormones.
在考虑了可能增加心脏病风险的一些因素之后，研究结果表明，每周食用豆腐一次以上与心脏病风险降低18%有关联，而一个月吃豆腐不到一次与该风险降低12%有关联。对于年轻女性和未服用激素的绝经后妇女，这种关联性更为强烈。
Lead study author Qi Sun, MD, ScD, said the results are in line with statistics from countries such as China and Japan, where individuals traditionally consume a diet high in isoflavones, however, other factors can also influence the development of heart disease, including physical exercise, family history, and lifestyle.
首席研究作者孙祺（Qi Sun）（医学博士，理学博士）表示，这些研究结果与传统饮食富含异黄酮的国家（如中国和日本）的统计结果一致；然而，其它一些因素（体育锻炼、家族史和生活方式等）也能够影响心脏病的形成。
“If their diet is packed with unhealthy foods, such as red meat, sugary beverages, and refined carbohydrates, they should switch to healthier alternatives,” Sun said. “Tofu and other isoflavone-rich, plant-based foods are excellent protein sources and alternatives to animal proteins.”
“如果他们（心脏病风险较高的人员）的饮食包含了很多不健康的食品，例如红肉、含糖饮料和精制碳水化合物等，那么他们应该改吃一些更健康的替代品，”孙祺说道。“豆腐及其它富含异黄酮的植物性食品是极佳的蛋白质来源，可以用来代替动物蛋白质。”
