保持大脑健康,请远离这7种食物1.TransFats反式脂肪Thegoodnewsisthatnotallfatsarebadforyou.However,aparticularkindoffatcalledtransfatdoeshaveadetrimentaleffectonthebrain.Transfatsarefoundnaturallyinanimalproductsincludingmeatanddairy,buteventhesearenotasproblematicastheindustriallyproducedtransfatsthatgetpumpedintoallsortsofpackagedfoods.好消息是，不是所有的脂肪对你都没好处。但是，反式脂肪确实会给大脑造成损害。反式脂肪天然存在于肉制品和奶制品等动物产品中，但这些脂肪都没有各种包装食品中的工业反式脂肪危害大。Otherwiseknownashydrogenatedoil,peoplewhoeatalotoftransfatintheformofmargarine,store-boughtbakedgoods,chipsandcrackers,frozenandcannedmeals,andcreamybeveragesareatagreaterriskforAlzheimer'sanddementia.Studieshaveshownthathighconsumptionoftransfatsalsoleadsto1保持大脑健康,请远离这7种食物earliercognitivedecline,lowerbrainvolume,andpoorermemory.工业反式脂肪又名氢化油，通过吃人造黄油、商店买来的烘焙食品、薯片和饼干、冷冻和罐头食品、奶油饮料摄入反式脂肪的人更容易得阿尔茨海默病和痴呆症。研究显示，大量摄入反式脂肪还会导致认知功能过早衰退、脑容量降低和记忆力减退。2.SugaryDrinks含糖饮料Sugarydrinkslikesoda,sportsdrinks,energydrinks,andevenfruitjuicehavelittletononutritionalvalue.Regularconsumptionofsugarydrinkscanleadtoawholehostofphysicalimpairments,includingtype2diabetes,highbloodpressure,highcholesterol,andyes–Alzheimer'sdiseaseordementia.汽水、运动饮料、能量饮料甚至果汁等含糖饮料都没有什么营养价值。经常摄入含糖饮料会引发一系列身体损伤，包括2型糖尿病、高血压、高胆固醇、阿尔茨海默病或痴呆症。Ahighintakeoffructosethat'sfoundinmanysugarydrinks,hasbeenshowntoreduce2保持大脑健康,请远离这7种食物learningability,memory,overallbrainfunction,andtheformationofnewneuronsinthebrain.Itmayalsoleadtoincreasedinflammationinthebrain,whichnegativelyaffectsalltypesofbrainfunction.研究显示，大量摄入果糖（许多含糖饮料都含有果糖）会降低学习能力、记忆力、整体脑功能和大脑中新神经元的生成速度。摄入果糖也许还会加重大脑炎症，对各种大脑功能产生负面影响。3.RefinedCarbs精制碳水化合物Refinedcarbohydratesareproductsmadewithprocessedgrains.Theymaynotnecessarilytastesweet,buttheybreakdownintosugarinyourbodyveryquickly.That'sbecausetherefiningprocessstripsallofthefiberandnutritionoutoftheoriginalgrain.Amealrichinrefinedcarbsrepresentsahighglycemicloadthatspikesyourbloodsugar.精制碳水化合物是用加工过的粮食制成的产品。它们的味道也许不是甜的，但很快就会在体内分解成糖。这是因为精制3保持大脑健康,请远离这7种食物过程中从原始谷物中剔除了所有的纤维和营养。富含精制碳水化合物的一餐意味着让血糖飙升的高血糖负荷。Thatcausesallthesameissuesasifyouhadeatenstraightsugar,includingmemoryimpairment,inflammation,andahigherriskofdevelopingdementia.Studieshaveshownthatchildrenwhoconsumedietshighinrefinedcarbohydratesscoreloweronnonverbalintelligencetests.Andelderlypeoplewhotakeinmorethan58%oftheirdailycaloriesinrefinedcarbshavetwicetheriskofmentalimpairmentanddementiathanthosewhoeatmorewholegrains,fruits,andvegetables.这就会引发和直接吃糖一样的问题，包括记忆力减退、炎症和更高的痴呆症风险。研究显示，摄入大量精制碳水化合物的孩子在非言语智力测试中得分更低。精制碳水化合物日常摄入量超过总热量58%的老年人智力受损和痴呆的风险比吃更多全谷物、水果和蔬菜的人高两倍。4.ProcessedandPackagedFoods高加工和包装食品Processedandpackagedfoodsremoveimportantnutritionfromwholefoodandreplaceitwit4保持大脑健康,请远离这7种食物hsugar,fat,andsalt.Thisisourso-calledWesterndiet,onewhichreliesonconvenienceandfastfoods.Andwegetit–peoplearebusyandsometimesitjustisn'tpossibletomakeyourownsauces,dressings,pastas,andbakedgoods.高加工和包装食品从天然食物中移除了重要营养，并用糖、脂肪和盐取而代之。这就是我们所谓的依赖方便食品和快餐的西式饮食。我们理解，人们很忙，有时候没
