Mediterranean¹ Diet Works--for Upper Crust

地中海式饮食只对上流社会有好处？

The Mediterranean diet is well known for its heart-healthy effects. It even sounds healthful: lots of fruits and veggies, whole grain and legumes. Plus olive oil, a bit of red wine. And fish and poultry² instead of red meat.

地中海式饮食以其有益于心脏健康而闻名。它甚至听起来就很健康：多吃水果和蔬菜，以及全谷物和豆类食物。还要吃橄榄油，喝点红酒。吃鱼肉和家禽肉，不要吃红肉。

\Now a study from Italy confirms that, if you follow the diet, you really can cut your risk of cardiovascular disease. But here's the catch: the benefits seem to only occur if you're financially comfortable or well educated.

意大利的一项新研究证实，如果你遵循地中海式饮食这种饮食习惯，真的可以降低患心血管疾病的风险。但问题是：似乎只有在经济条件优渥或受过良好教育的人群中，这种好处才会体现出来。

The finding is in the International Journal of Epidemiology.

这项研究发表在《国际流行病学杂志》上。

Researchers tracked 19,000 men and women living in southern Italy during a four-year interval³. After controlling for habits like smoking and exercise, the team found that volunteers who stuck more closely to the diet enjoyed greater protection against heart problems—but only for if they were college-educated, or earned more than 40,000 euros a year, or about $47,000.

研究人员对居住在意大利南部的1.9万名男女进行了为期四年的跟踪调查。在有效控制吸烟和锻炼等习惯的情况下，研究小组发现，那些更加遵循这一饮食习惯的志愿者们更能抵御心脏问题——但前提是他们要受过大学教育，或者年收入超过4万欧元(约合47000美元)。

The scientists think that higher-income, educated individuals tend to prepare vegetables in healthier ways—perhaps preserving more vitamins and antioxidants. They also favored fish and whole grain bread, and ate more organic vegetables. And perhaps they're simply able to afford higher quality foods. Better olive oil, for example.

科学家们认为，高收入、受过良好教育的人倾向于以更健康的方式准备蔬菜——或许他们更注重保存维生素以及抗氧化。他们也更喜欢鱼和全麦面包，倾向于吃更多的有机蔬菜。也许在仅是因为他们买得起高质量的食物。例如，质量较好的橄榄油。

"You can buy the two- to three-euro bottle or you can have a 10-euro bottle." Study author Marialaura Bonaccio, an epidemiologist. "Probably these two bottles are different in their nutritional⁴ contents—in the context for example of polyphenols or other nutritional compounds."

“你可以买2到3欧元一瓶的（橄榄油），也可以买10欧元一瓶的（橄榄油）。”流行病学家Marialaura Bonaccio，同时也是该研究的作者说道。“可能这两种瓶装橄榄油的营养成分不同——比如它们的多酚或其他营养成分的含量不同。”

Seems that the Mediterranean diet includes few foods that we consider rich. But to get the full benefits, it helps if you are.

看起来地中海饮食仅包含了少数我们认为营养丰富的食物。但如果你恰是这类人，那它就能帮你从中获益。
