章鱼logo乐队:请记住：鱼吃的越多，你的记忆力越好

请记住：鱼吃的越多，你的记忆力越好（翻译版）2007-11-29     你的钥匙放错了地方？你不能想起来一个人的样子？最近研究表明仅仅多吃鱼就能使你减少这些“高级活动”的频率，并且据最近挪威的研究显示鱼吃的越多，这种效应越明显。     研究者发现，经常吃鱼的老年人在记忆力、抽象概念、注意力、方向感和语言流畅性测试中的得分较高。     英国牛津大学的校长A. David Smith 戴维德史密斯博士说“对于以上六个认知能力的测试，那些吃鱼的人表现的更出色。”除此之外，史密斯博士还指出，如果每天能够吃鱼80克，这种作用则更明显。     史密斯和他的同事们对2031位老年人的认知能力和每日对鱼和海鲜的摄入量量进行了评估，这些老年人年龄在70到74岁，大多来自挪威西部。据美国临床营养学杂志报道，在这些老年人当中，有1951位每天吃活的、冷冻的或者罐装的鱼，以及鳕鱼肝、鱼油等鱼产品超过10克，剩下的80位参与者每天吃鱼少于10克。研究表明在以上六个认知测试中那些在主食中吃鱼较多的人比那些不吃鱼的人在五个测试中都表现的出色。     研究者还注意到，多吃加工鱼或鱼三明治也同样能通过认知测试中的三项实验。而与此相比，那些只吃鱼油的老年人则只能通过一项测试。     研究者还提出了进一步研究的目标以确定那些由吃鱼和海鲜对认知能力的裨益是由鱼的类型，鱼的品种决定还是由加工过程决定。史密斯说：“此外，我们需要知道鱼肉中的哪种营养对我们重要”，认知能力的提高，不仅仅是因为欧米嘎－3的作用，因此瘦鱼的营养与肥鱼一样好。 原文链接：http://www.wellenglish.com/english/2007-11/1428.htm Misplaced your keys? Can‘t place that face? Study findings suggest that you may be able to lessen the frequency of these "senior moments‘ simply by eating more fish. And the more fish you eat, the bigger the effect, according to research conducted in Norway.Investigators found that elderly men and women who more frequently ate fish scored better on memory, visual conception, spatial motor skills, attention, orientation, and verbal fluency tests."All six cognitive tests were performed better by those who ate fish," principal author Dr A. David Smith of the University of Oxford, UK, said Health. Furthermore, he added, the effect was stronger as fish consumption increased up to a limit of about 80 grams per day.Smith and colleagues assessed cognitive ability and the average daily amount of fish and seafood in the diets of 2,031 men and women, between 70 and 74 years old, recruited from the general population of Western Norway.Overall, 1951 of the study participants reported eating 10 or more grams per day of fresh, frozen, or canned fish and seafood, or fish products such as cod liver and fish oil, the investigators report in the American Journal of Clinical Nutrition. The remaining 80 participants ate less than 10 grams daily.Study participants who reported more frequent consumption of fatty or lean fish as their main meal performed significantly better in five of the six cognitive tests, compared with those who did not eat fatty or lean fish.Processed fish or fish sandwiches were likewise associated with better performance on three of the cognitive tests, the investigators note. By contrast, seniors who consumed only fish oils performed better on just one of the tests.The investigators propose the need for additional research to determine whether the cognitive benefits from fish and seafood consumption depend on the type, the species of fish or on the preparation."Secondly, we need to discover what components of fish are important," Smith said. Since we found that lean fish was as good as fatty fish, it may not just be the omega-3 fatty acids that confer cognitive benefit, he commented.
