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 这两项研究深入证实了饮食对于防癌的作用癌症防治教授认为，在全部种类的癌症中，多达三分之二全部是由吸烟、节食及缺乏锻炼等不健康的生活方法造成的 美国全国癌症研究所和夏威夷大学的研究人员发觉，在5岁至11岁时常常吃豆腐、味噌等豆类食品的女性患乳腺癌的几率要低58%至于豆类食品为何能够防癌还不清楚，不过大豆中所含的名叫异黄酮的化合物含有雌性激素的作用 另一项研究表明，一周吃鱼最少五次的男性患结肠癌的风险要比那些一周全部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会引发发炎，这可能会刺激肿瘤的生长 Ifyou'remiddle-agedandyourmemory'snotwhatitusedtobe,checkthebathroomscale,researcherswarned,suggestingoverweightpeopletendtoscoremorepoorlyontestsofmemorythantheirthinnerpeersdo.

研究表明，超重的人记忆测试的得分要比较瘦的人低 研究发觉，体重偏大的中年人以后患老年痴呆症的可能性较大 研究汇报在《神经学》期刊上发表，研究人员推断，心血管疾病及糖尿病的高发觉象能够解释其中的原因另外，脂肪细胞所产生的物质，如瘦体激素，对大脑有直接影响 此项研究将调查对象的智力和体重指数进行了对比体重指数指的是身高和体重之间的百分比，关键用来衡量一个人是否偏胖或肥胖体重指数为25或25以上的人偏胖，达成30或30以上的人则为肥胖 研究人员还对体重指数和认知功效间的关系进行了研究，她们在法国对2223位年纪在32岁至62岁间的健康男女进行了认知测试 研究发觉，体重指数越大，认知测试的得分越低其中一项"单词记忆"的测试结果表明，在16个单词中，体重指数为20的人平均能记住9个，而体重指数为30的人平均只能记住7个 Peoplewhodonotgetenoughsleeparemorethantwiceaslikelytodieofheartdisease,accordingtoalargeBritishstudyreleasedMonday.

现在其中的原因尚不清楚，但研究人员称，睡眠不足会造成血压升高，从而增大患心脏病和中风的风险 一项针对1万名政府职员、长达17年的跟踪调查表明，每晚睡眠时间从七个小时降低到五个小时或更少的人因多种原因此死亡的几率是睡眠正常者的倍，而且死于心血管疾病的风险也增加了1倍多 沃里克大学医学院的心血管药品学教授弗朗西斯哥?卡普西奥在英国睡眠学会在剑桥召开的一年一度的研讨会上说，这一研究结果揭示了忙碌的当代生活中潜在的危险 她在接收记者采访时说：“三分之一的英国人和超出40%的美国人每晚的睡眠时间经常达不到五个小时，因此这个问题不可小视 以前有调查发觉轮班及睡眠中止会对健康产生潜在威胁但卡普西奥及其同事的这项调查则首次揭示了睡眠时间长短和死亡率之间的关系该调查由英国政府和美国基金提供资助 该调查对年纪在35岁至55岁之间的人在1985年至1988年和1992年至1993年两个阶段的睡眠模式进行了探究，并对这一人群截至2021年的死亡率进行了追踪 调查还考虑到了调查对象的初始年纪、性别、是否吸烟喝酒、体重指数、血压及胆固醇指标等其它可能的风险原因 卡普西奥说，睡眠时间过长也可能造成如抑郁症及癌因性疲乏等其它健康问题。
她说：“就预防而言，我们的研究结果表明，每晚睡眠时间连续保持在七小时左右最益于身体健康 篇二：大学英语演讲稿3分钟 wheniwasseven,,',andbeganmycolorfuldreamintheenglishworld. ,,iwanttogotolondontoo,,iwillbeveryhappy.
