Vitamin E supplements(补充品)，which millions take in the hope of longer, healthier lives, may do more harm than good, researchers reported on Wednesday. In fact, people taking high doses(剂量)of vitamin E may in some cases be more likely to die earlier, although the reasons are not clear, said Dr. Edgar Miller of Johns Hopkins University in Baltimore, who led the study.“I think people take vitamin E because they think it is going to make you live longer, but this(study)doesn’t support that.”Miller told reporters. Miller and colleagues reanalyzed 19 studies of vitamin E and health between 1993 and 2004. The tests involved more than 136,000 mostly elderly patients in North America, Europe and China. People who took 200 international units of vitamin E a day or more died at a higher rate during the study, which lasted three years, than people who did not take supplements, they told a meeting of the American Heart Association.“It’s about a 5 percent increased risk at 45 years in the tests combined together，”Miller said.“That doesn’t sound like a lot but if you apply it to 25 percent of the (U.S.)adult population taking vitamin E, that is significant.” Miller, whose findings are also being published online by the Annals of Internal Medicine, said twothirds of people who take vitamin E supplements take 400 IU or more.“We don’t think that people need to take vitamin E supplements, which they can get enough from the diet,”he said. Nuts, oils, whole grains and green leafy vegetables are all rich in vitamin E. 小题1: People take vitamin E supplements, hoping that________.
