喝咖啡的人常被人误认为小资，其实小资是有专门定义的。某时尚刊物曾说：要做小资很难，收入要够标准，牛仔裤、运动鞋甚至袜子都有固定的牌子。

科学研究又一次证明了做小资不仅很难，还很危险。

If you rely on coffee, tea, or cola for a daily pick-me-up, consider this: New studies reveal that caffeine can have an effect on your blood sugar, cancer risk, and more. Here, the surprising up- and downsides of this stimulant.

 

* It may protect against ovarian cancer In one Harvard study, women who consumed at least 500 milligrams of caffeine were 20 percent less likely to develop ovarian cancer than those who got less than 136 milligrams. However, the researchers aren't certain how caffeine may guard against the disease and say it's too soon to recommend upping your caffeine intake.

 

* It raises diabetics' blood sugar levels Research shows that coffee can lower your diabetes risk, but if you already have the disease or are at risk for it, you may need to cut back on the java. A Duke University study found that when diabetics consumed 500 milligrams of caffeine a day, their blood sugar readings were 8 percent higher.

 

* It raises miscarriage risk Taking in 200 milligrams of caffeine, or the equivalent of about two cups of coffee or two energy drinks, a day during pregnancy may double the risk of miscarriage, reports a study in the American Journal of Obstetrics and Gynecology.
