在有效控制吸烟和锻炼等爱好的情况下,研究小组发现,那些严格遵循地中海饮食的志愿者在对抗心脏疾病时享有更强的保护,但前提是他们接受过大学教育或年收入超过4万欧元(约合4.7万美元)。
The scientists think that higher-income, educated individuals tend to prepare vegetables in healthier ways -- perhaps preserving more vitamins and antioxidants.
科学家认为,收入高、受过良好教育的人倾向于以更健康的方式烹调蔬菜,也许这种方式保留了更多的维生素和抗氧化剂。
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.
他们也喜欢鱼肉和全麦面包,也会多吃有机蔬菜。也许他们只是有能力买得起更高质量的食物。比如,更优质的橄榄油。
"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 products Probably these two bottles are different in their nutritional contents -- in the context for example of polyphenols or other nutritional compounds."
该研究的作者、流行病学家玛丽亚劳拉·伯纳西奥说道:“你可以买两三欧元一瓶的橄榄油,也可以买10欧元一瓶的橄榄油。可能这两种产品在营养成分上--比如多酚或其它营养化合物,会有所不同。”
