Apples have been as not only a delicious fruit， but also as an effective way to improve your health. Research suggests that eating apples can benefit your heart， your teeth， and your energy level. Eating a higher amount of fruits and vegetables in general can also let you have a lower risk for chronic diseases including coronary heart disease， asthma， diabetes， cancer and perhaps even Alzheimer’s disease.
　　苹果不仅因其美味倍受热捧，而且对健康有十分有利的影响。研究表明，多吃苹果让你心好、牙好、精神好。一般说来，多吃蔬菜水果能降低罹患冠心病、哮喘、糖尿病、癌症和老年痴呆等慢性病的风险。
　　So， is it true that apples are a super fruit？ Do they have an effect on the health and functioning of your brain？ The research is limited， but it does show some promise.
　　那么，苹果真的是万能水果么？它们真的能影响大脑健康和机能么？关于这方面的研究虽然有限，但的确被证明有一定可能性。
　　A Review of 2 Research Studies
　　回顾两项相关研究
　　The effect of apples on memory
　　苹果对记忆的影响
　　One study published in the Journal of Alzheimer’s Disease used older mice who were fed a small diet. These mice then showed a decline in their cognitive ability shown by poor performance in finding a way out of a maze. However， after apple juice was added to their drinking water for a month， their memory was restored and they were able to efficiently find the way out of the maze again. （Often， research on mice translates to humans， which would suggest that apple juice may improve our memory.）
　　一项发表于《阿兹海默症期刊》的课题研究了一组年老的老鼠在食物摄取量不足的条件下的行为。在迷宫测试中，这些老鼠表现欠佳，显示出认知能力的下降。然而，把苹果汁加到老鼠的食谱里一个月后，它们的记忆力恢复到原来的水平且又能走出迷宫了。（对老鼠进行的研究常能反映到人类身上，也就是说，苹果汁也能提高我们的记忆力）
　　Will eating an apple right before a test help you perform better？
　　在考试前吃个苹果会让你表现更佳么？
　　A second study tested the immediate effects of apples and spinach （both separately and together） and found no change in the cognitive functioning of the persons who took part in the test right after eating the foods. The study did not， however， measure if a diet that included apples affected cognition or risk of dementia over time.
　　第二项研究检验了吃完苹果和菠菜（分别吃和同时吃）是否有立竿见影的效果，发现刚吃完蔬菜水果后，参加者的认知能力并没有改变。然而这项研究并未检测长期将水果纳入膳食对认知能力或痴呆症病发几率的影响。
