We have heard a lot about the health benefits of tea, especially green tea. It is high in polyphenols, compounds with strong antioxidant activity that in test-tube and animal models show anticancer and heart-protective effects. Good clinical studies are few, however, and although physicians tell their patients to drink green tea, there hasn’ t been any definite proof of the value of that advice.
A team of Japanese researchers was able to link green tea consumption with decreased mortality from many causes—including heart disease. The researchers tracked 40,530 healthy adults ages 40 to 79 in a region of northeastern Japan where most people drink green tea, following mem for up to 11 years. Those who drank five or more cups of green tea a day had significantly lower mortality rates than those who drank less than one cup a day. There were also fewer deaths from cardiovascular disease.
But no such association was seen with deaths from cancer. Nor was consumption of oolong or black tea connected with any decrease in mortality. Those teas are easier to be combined with oxygen in processing, which not only darkens the color of the leaves and changes their flavor but also reduces their polyphenol content.
Coffee is more complicated. It has received both gold stars and black marks in medical literature. It, too, contains antioxidants, although they are less well studied that tea polyphenols. Evidence for the health benefits of coffee is growing, however. A group of investigators from Finland, Italy and the Netherlands reports that coffee seems to protect against age-related decline in mental capacity. The scientists studied 676 healthy men born from 1900 to 1920 and followed them for 10 years, using standardized measures of brain function. Their conclusion; the men who consumed coffee had significantly less decline in mental capacity than those who didn’ t. Three cups a day seemed to provide the most protection.
Population studies like those help us form assumptions about relationships between dietary habits and long-term health. We still have to test our suppositions in controlled conditions, and measure the effects of coffee and tea on various systems of the body.
The Japanese study seems to have confirmed the positive effect of green tea on______.
选项
A、young adults
B、Asian people
C、patients with cancer
D、patients with heart disease
答案
D
解析
细节题。从文章第二段第一句“A team of Japaneseresearchers was able to link green tea consumption with decreasedmortality from many causes--including heart disease.”及第三句“Those who drank five or more cups of green tea a day had signifi—cantly lower mortality rates than those who drank less than one cup aday.”可知,13本研究者将饮用绿茶与诸如心脏病等因素导致的死亡率下降相联系,与每天饮用不到一杯绿茶的人相比,每天饮用五杯以上绿茶的人的死亡率要低得多,故选D。
