WASHINGTON (Reuters) - Drinking more than three cups of coffee a day helped protect older women against some age-related memory decline, French researchers said on Monday, giving women more reason to love the world's most popular stimulant.
Men did not enjoy the same benefit, they said.
"The more coffee one drank, the better the effects seemed to be on (women's) memory functioning in particular," said Karen Ritchie at the French National Institute of Medical Research, whose work appears in the journal Neurology.
The researchers followed more than 7,000 men and women in three French cities, checking their health and mental function and asking them about their current and past eating and drinking habits, their friends, and their daily activities.
They used this information to sort out the specific role caffeine played in these women's lives.
They found that women who drank more than three cups of coffee per day, or its caffeine equivalent in tea, retained more of their verbal and -- to a lesser extent -- visual memories over four years.
These women had a 33 percent lower odds of having verbal memory declines and 18 percent lower odds of having visual and spatial memory declines, compared to women who drank one cup or fewer per day.
The effect also depended on age, with women over 80 reaping more benefits from these beverages than those who were 10 to 15 years younger, Ritchie's team wrote. It was unclear whether current or former coffee consumption made the difference.
Some studies in mice have suggested that caffeine might block the buildup of proteins that lead to mental decline.
Ritchie is not sure why only women benefited in her study.
"Our best guess is that women don't metabolize coffee in the same way (as men)," she said in a telephone interview.
Ritchie plans to follow the women longer to see if caffeine delays the onset of dementia -- the mental confusion that signals Alzheimer's disease and other brain disorders.
She said people should weigh any brain gains derived from caffeine against other effects of the stimulant, including raised blood pressure.
The average American drinks one to two cups of coffee a day, according to the National Coffee Association. 本人认领, 24小时若未交稿, 请其他战友认领. Coffee may slow memory declines in women: study

研究表明，咖啡可减缓妇女记忆力下降
WASHINGTON (Reuters) - Drinking more than three cups of coffee a day helped protect older women against some age-related memory decline, French researchers said on Monday, giving women more reason to love the world's most popular stimulant.
华盛顿路透社消息，法国研究人员周一称，老年妇女每天饮用三杯以上的咖啡，可有助于减缓与年龄有关的记忆力下降，这一发现为妇女对这一全球最受欢迎的刺激性饮品的热衷提供了更多的理由。
Men did not enjoy the same benefit, they said.
他们称，男人却不能受益。
"The more coffee one drank, the better the effects seemed to be on (women's) memory functioning in particular," said Karen Ritchie at the French National Institute of Medical Research, whose work appears in the journal Neurology.
“喝咖啡越多，对妇女记忆功能的效果似乎越好。”法国医学研究所Karen Ritchie说道。该研究发表在《神经病学》杂志上。
The researchers followed more than 7,000 men and women in three French cities, checking their health and mental function and asking them about their current and past eating and drinking habits, their friends, and their daily activities.
研究人员对法国三个城市的7000多名男女进行了跟踪研究，检查他们的健康和智力状况，并询问有关他们目前和过去饮食习惯、朋友以及日常活动情况。
They used this information to sort out the specific role caffeine played in these women's lives.
他们通过这些信息以确定咖啡因在这些妇女的生活中所起的特殊作用。
They found that women who drank more than three cups of coffee per day, or its caffeine equivalent in tea, retained more of their verbal and -- to a lesser extent -- visual memories over four years.
他们发现，那些每天饮用三杯以上咖啡或与之咖啡因相当的茶水的妇女，四年期间她们保持更多的非文字记忆和视觉记忆（较少）。
These women had a 33 percent lower odds of having verbal memory declines and 18 percent lower odds of having visual and spatial memory declines, compared to women who drank one cup or fewer per day.
与那些每天饮用一杯或更少咖啡的妇女相比，他们的非文字记忆力和视觉及空间记忆力下降几率分别减少33%和18%。
