,儿童时期经常吃豆类食品的女性患乳腺癌的风险较小。另一组研究人员则向美国癌症研究协会提出,一周吃几次鱼的男性患结肠癌的几率较小。 这两项研究进一步证明了饮食对于防癌的作用。癌症防治专家认为,在所有种类的癌症中,多达三分之二都是由吸烟、节食及缺乏锻炼等不健康的生活方式造成的。 美国全国癌症研究所和夏威夷大学的研究人员发现,在5岁至11岁时经常吃豆腐、味噌等豆类食品的女性患乳腺癌的几率要低58%。至于豆类食品为什么可以防癌还不清楚,不过大豆中所含的名叫异黄酮的化合物具有雌性激素的作用。 另一项研究表明,一周吃鱼至少五次的男性患结肠癌的风险要比那些一周都吃不到一次鱼的男性低40%。很多鱼类中所富含的Omega—3脂肪酸能够抑制环氧化酶2的活性。环氧化酶2会引起发炎,这可能会刺激肿瘤的生长。 篇二 LadiesandGentlemen,Goodafternoon!

Thankyou! 青春 青春不是指岁月,而是指心态。粉嫩的脸,红润的唇,矫健的膝并不是青春。青春表现在意志的坚强与懦弱。想象的丰富与苍白、情感的充沛与贫乏等方面。青春是生命深处清泉的喷涌。 青春是追求。只有当勇气盖过怯弱、进取压倒苟安之时,青春才存在。果如此,则60见之长者比20岁之少年更具青春活力。仅仅岁月的流逝并不能使他们衰老。而一旦抛弃理想和信念,则垂垂老也。 岁月只能使皮肤起皱。而一旦丧失生活的激情,则连灵魂枯老,使人生枯如死水,毫无活力。60岁长者也好,16岁少年也罢,每个人的内心深处都渴望奇迹,都如孩子一般眨着期待的双眼,期待着下一次,期待着生活的情趣,你我灵魂深处都有一座无线电中转站———只有你我年轻,则总能听到希望的呼唤,总能发出喜悦的欢呼,总能传达勇气的讯号,总能表现出青春的活力„„„ 一旦青春的天线倒下,你的灵魂即为玩世不恭之雪、悲观厌世之冰覆盖;即使你年方 20.其实你已垂垂老也。而只要你青春的天线高高耸起,就可以随时接收到乐观的电波——即使你年过八旬,行将就木,而你却仍然拥有青春,你仍然年轻。 谢谢! 篇三 Sayinggoodbyetochildhood,westepintoanotherimportanttimeinthepaceofyoung,facingnewsituations,dealingwithdifferentproblems..... everyonehashisownunderstandingofyoung,itisaperiodoftimeofbeautyandwonders,onlyafteryouhave experiencedthesour,sweet,bitterandsaltycanyoureallybecomeapersonofsignificance.thretimeofyoungislimitted,itmaypassbywithoutyourattention,andwhenyoudiscoverwhathashappened,itisalwaystoolate.graspingtheyoungwellmeansabettertimeiswaitingforyouinthenearfuture,orthesituationmaybeopposite. havingaviewonthesegreatmeninthehistoryofhunmanbeing,theyallmadefulluseoftheiryouthtime,todothingsthatareusefultosociety,tothewholemankind,andasacosquence,theyarerememberedbylater generations,admiredbyeveryone.sodosomethinginthetimeofyoung,althoughyoumaynotgetachievementsasthesegreatmendid,thoughnotforthewholeword,justforyoueself,forthosearound! theyoungisjustlikebloomingflowers,theyaresobeautifulwhenblooming,theymakepeoplefeelhappy,butwithtimepassingby,aftertheywithers,moetpeoplethinktheyareugly.andsoitisthesamewithyoung,weareenthusiasticwhenweareyoung,thenwemayloseourpassionwhengettingolderandolder.sowemusttreasureit,don'tletthelimittedtimepassby,leavingnothingofsignificance.
