Women who drank three or more cups of coffee a day were 30 percent less likely to have memory decline at age 65 than whose who drank one cup or less daily. And the benefit increased with age. Women over age 80 who drank three or more cups of coffee a day were about 70 percent less likely to have memory decline than those who drank one cup or less, the researchers said.
Caffeinated tea had the same effect in the women, the study found, although more was needed to get the same caffeine boost. "Count roughly two cups of tea for a cup of coffee," said study leader Karen Ritchie of INSERM, the French National Institute for Health and Medical Research.
But the researchers didn’t find a similarly protective effect in men, although other studies have found a benefit to males.
How might caffeine help ward off cognitive decline? "It is a cognitive stimulant," said Ritchie. It also helps to reduce levels of the protein called beta amyloid in the brain, she said, "whose accumulation is responsible for Alzheimer’s disease but which also occurs in normal aging."
Ritchie said she wasn’t sure why men in the study didn’t benefit from caffeine. "Our hypothesis is that either women metabolize caffeine differently than men, or there may be an interaction of the caffeine with the sex hormones, the estrogen-progesterone balance," she said.
The French study confirms previous research, said William Scott, professor of medicine at the University of Miami Miller School of Medicine, who has researched caffeine’s beneficial effects against Parkinson’s disease, also a neurodegenerative disorder.
As for caffeine only protecting women, Scott noted that just 2,800 of the 7,000 study participants were men, and the results might have differed if more men were included.
A study published in February in the European Journal of Clinical Nutrition looked at 676 healthy men and found that regular coffee drinkers had a lower rate of cognitive decline over a 10-year follow-up than those who didn’t drink coffee. Those who drank three cups daily had the least signs of decline.
Both Scott and Ritchie agreed that more study is needed. Ritchie’s research will next look at the relationship between caffeine and Alzheimer’s. [br] As it is indicated in the first paragraph, how does coffee influence women’s memory?
选项
A、The older the woman was, the more remarkable her memory was.
B、The more coffee the woman drank, the more slowly her memory declined.
C、The older the woman was, the more slowly her memory declined.
D、The more coffee the woman drank, the more remarkable her memory was.
答案
C
解析
首段第2句概括了该段的主要内容,句中的benefit指的是记忆衰退的减缓。因此本段内容为:年龄越长,记忆衰退就比同龄人越慢,即C。本段关注的是咖啡影响记忆的衰退程度,而非咖啡是否能增强记忆,A、D(记忆力的好坏)在本段并未论及;虽然本段对比了喝三杯或更多咖啡的女性与喝一杯或更少的女性的记忆衰退程度,但这并不意味着咖啡喝得越多越好,因此B、D中的the more coffee the woman drank这个前提不正确,故两项均错。
