Soy food good for womenWomen who ate soy regularly as children have a lower risk of breast cancer, American researchers report. And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research. The studies add to a growing body of evidence about the role of diet in cancer. Cancer experts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of exercise. The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 5 to 11, reduced their risk of developing breast cancer by 58 per cent. It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen-like effects. A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week. Many kinds of fish are rich in omega-3 fatty acids, which interfere with the cyclooxygenase-2 or COX-2 enzyme. COX-2 affects inflammation, which may play a role in tumour growth.据美国研究人员报告，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。
If you're middle-aged and your memory's not what it used to be, check the bathroom scale, researchers warned, suggesting overweight people tend to score more poorly on tests of memory than their thinner peers do. The findings suggest that a heavier weight in middle age may mean a higher risk of dementia later in life. Reporting in the journal Neurology, the researchers speculated that higher rates of cardiovascular disease or diabetes might help explain the link. But it's also possible that substances produced by fat cells, such as the hormone leptin, have direct effects on the brain. The study compared mental abilities to body mass index (BMI), a measurement of weight in relation to height used to define overweight and obesity. A BMI of 25 or more indicates overweight, and 30 or more is obese. The study also investigated the relationships between BMI and cognitive function in 2,223 healthy men and women between the ages of 32 and 62 in France through the use of four cognitive tests. The study found a higher BMI was associated with lower cognitive test scores. Results from a test involving word memory recall show people with a BMI of 20 remembered an average of nine out of 16 words, while people with a BMI of 30 remembered an average of seven out of 16 words. 研究人员提醒，如果你已步入中年，发现自己的记忆力不如从前，那么你得小心体重了。
研究表明，超重的人记忆测试的得分要比较瘦的人低。
研究发现，体重偏大的中年人今后患老年痴呆症的可能性较大。
研究报告在《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现象可以解释其中的原因。
此外，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与体重指数进行了对比。
体重指数指的是身高和体重之间的比例，主要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，达到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能间的关系进行了研究，他们在法国对2223位年龄在32岁至62岁间的健康男女进行了认知测试。
研究发现，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。
People who do not get enough sleep are more than twice as likely to die of heart disease, according to a large British study released Monday.Although the reasons are unclear, researchers said lack of sleep appeared to be linked to increased blood pressure, which is known to raise the risk of heart attacks and stroke.A 17-year analysis of 10,000 government workers showed those who cut their sleep from seven hours a night to five or less faced a 1.7-fold increased risk of death from all causes and more than double the risk of cardiovascular death.The findings highlight a danger in busy modern lifestyles, Francesco Cappuccio, professor of cardiovascular medicine at the University of Warwick's medical school, told the annual conference of the British Sleep Society in Cambridge.A third of the population of the UK and over 40 percent in the US regularly sleep less than five hours a night, so it is not a trivial problem, he told reporters.Previous research has highlighted the potential health risks of shift work and disrupted sleep. But the study by Cappuccio and colleagues, which was supported by British government and US funding, is the first to link duration of sleep and mortality rates.The study looked at sleep patterns of participants aged 35-55 at two points in their lives - 1985-88 and 1992-93 - and then tracked their mortality rates until 2004.The results were adjusted to take account of other possible risk factors such as initial age, sex, smoking and alcohol consumption, body mass index, blood pressure and cholesterol.Cappuccio said it was possible that longer sleeping could be related to other health problems such as depression or cancer-related fatigue.In terms of prevention, our findings indicate that consistently sleeping around seven hours per night is optimal for health, he said.(Agencies) 本周一公布的一项大规模英国调查表明，睡眠不足的人死于心脏病的几率是睡眠充足者的两倍多。
目前其中的原因尚不清楚，但研究人员称，睡眠不足会导致血压升高，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减少到五个小时或更少的人因各种原因而死亡的几率是睡眠正常者的1.7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物学教授弗朗西斯哥•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，这一研究成果揭示了忙碌的现代生活中潜在的危险。
他在接受记者采访时说：“三分之一的英国人以及超过40%的美国人每晚的睡眠时间常常达不到五个小时，所以这个问题不可小视。
”此前有调查发现轮班及睡眠中断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与死亡率之间的关系。
该调查由英国政府和美国基金提供资助。
该调查对年龄在35岁至55岁之间的人在1985年至1988年以及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2004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龄、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因素。
卡普西奥说，睡眠时间过长也可能导致如抑郁症及癌因性疲乏等其它健康问题。
他说：“就预防而言，我们的研究结果表明，每晚睡眠时间持续保持在七小时左右最益于身体健康。

It is in a strong body. Secondly, we must pay attention to our diet, not to drink too much wine, water, every day at least eight cups of water; Deliberately not to lose weight, did you have no health benefits.

But if our health was taken away, we would surely die. That is why we always try to eat in a healthy way and exercise regularly. Living a long life may be a lot easier than you think. And there are some bad habit we need to get rid of 。
A report suggests 10 steps to a longer and healthier life. 1. Shun cigarette smoke, separate yourself from smokers. . Become a nag and tell anyone you know who smokes to stop. 2. Keep moving. The U. S. Department of Health and Human Services suggests every adult get at least 150 minutes of moderate aerobic activity a week. Sessions should be at least 10 minutes long. 3. Eat like an Aegean. Follow the Mediterranean diet pattern of mostly plant foods, limiting animal protein to fish and poultry, using olive oil as the principal fat and use wine in moderation. 4. Mind your body mass index. Obesity increases the risk of diabetes 20 times and substantially boosts the risk of developing high blood pressure, heart disease, stroke and gallstones. 5. Lift a glass, but only one. Alcohol's effects become more insidious as women age because the body's water-to-fat ratio declines over the years. 6. Don't run up a sleep debt. Medical evidence suggests we need seven to nine hours of sleep daily, but more than 60 percent of women regularly fall short of that goal. 7. Be your own best advocate on health issues. 8. Keep connected. Older women who remain socially active live longer and healthier lives than their solitary counterparts 9. Avoid stress. Find techniques to reduce stress and its effects. 10. Use supplements selectively. Experts agree the best way to get nutrients is through food. Only calcium and vitamin D, essential in preserving bone density, are recommended supplements. And that includes 1,200 mg of calcium and 1,000 mg of vitamin.
遇到困难的英语演讲稿
The Importance of Keeping Optimistic in front of difficulties Honourable judges, ladies and gentlemen, Good afternoon! Today I would like to talk about the importance of keeping optimistic. When we encounter difficulties in life, we notice that some of us choose to bury their heads in the sand. Unfortunately, however, this attitude will do you no good, because if you will have no courage even to face them, how can you conquer them? Thus, be optimistic, ladies and gentlemen, as it can give you confidence and help you see yourself through the hard times, just as Winston Churchill once said, “An optimist sees an opportunity in every calamity; a pessimist sees a calamity in every opportunity.” Ladies and Gentlemen, keeping optimistic, you will be able to realize, in spite of some hardship, there’s always hope waiting for you, which will lead you to the ultimate success. Historically as well as currently, there are too many optimists of this kind to enumerate. You see, Thomas Edison is optimistic; if not, the light of hope in his heart could not illuminate the whole world. Alfred Nobel is optimistic; if not, the explosives and the prestigious Nobel Prize would not have come into being. And Lance Armstrong is also optimistic; if not, the devil of cancer would have devoured his life and the world would not see a 5-time winner of the Tour De France. A rose may be beautiful, or maybe not; that depends on your attitude only, and so does success, so does life. Hindrances and difficulties do exist, but if you are optimistic, then they are only episodes on your long way to the throne of success; they are more bridges than obstacles! Now I prefer to end my speech with the great British poet Shelley’s lines: “If winter comes, can spring be far behind?” Thank you! 在困难面前保持乐观的重要性 尊敬的评委、女士们、先生们： 下午好
今天我想谈一谈保持乐观的重要性。
我们注意到，当在生活中遇到困难时，我们中的有些人选择逃避它们。
但令人遗憾的是，这样的态度对你没有任何好处，因为如果你连面对它们的勇气都没有的话，你怎么去征服它们呢
因此，乐观起来吧，女士们、先生们，因为它会带给你信心，帮助你渡过难关。
正如温斯顿·丘吉尔所说，“乐观者在每次灾难中都看到机遇；悲观者在每次机遇中都看到灾难”。
女士们，先生们，困难是存在的，但如果你保持乐观，你就会意识到永远有希望在等着你，它会把你领向最终的成功。
不管是历史上还是现实中，这样的乐观者总是不胜枚举。
你看，托马斯·爱迪生是乐观的，如果不是的话，他心中那希望的明灯就不能照亮整个世界；阿尔弗雷德·诺贝尔是乐观的，如果不是的话，那炸药和享有很高声望的诺贝尔奖就不会诞生；兰斯·阿姆斯特朗也是乐观的，如果不是的话，那癌症的病魔早已吞噬了他的生命，这个世界就会少了一位五届环法自行车赛冠军得主. 玫瑰花可能很美，也可能不美，这，仅仅取决于你的态度；而成功也如此，人生也如此。
困难和阻碍的确存在，但是如果你很乐观的话，那它们就仅仅是我们通向胜利之冠的漫长道路上的小插曲；与其说它们是障碍，不如说它们是桥梁
此刻，我想以伟大的英国诗人雪莱的一句诗来作为我的结尾：“冬天来了，春天还会远吗?”谢谢

My DreamI dream of being a doctor.My mother is a doctor. She always has to work extra hours and comes home late and tired. She has to go to the hospital immediately any time she is needed, no matter how late it is at night. When I was very little and still in primary school, I once asked her why she chose such a boring and hard job. She answered with a smile, “Yes I am sometimes very tired but seeing my patients getting better and better makes me happy from the bottom of my heart.”As I grow up, I gradually come to understand her words and realize doctors are noble. I made up my mind to be a doctor when I was in junior school and this has never changed since then.I really hope to see a world where there is no cancer, no Aids, no fatal disease, no one suffering from illness. But this is only a fantasy. What about the reality? There are still many many people who are faced with disastrous disease and suffering from constant pain. There are still many many people living in miserable condition and live miserably. There are still many many people dying of cancer and leaving the beautiful world reluctantly. All those things make me feel sad because I think everyone has the right to live . I want to help the sick and reduce their pain as much as I can. I want to bring a healthy body to the patients and save their lives as many as I can. I want to see people cured ,living happily with their families and friends after my treatment. So I want to be a doctor ,an angel in white.When I become a doctor, I will cherish each life regardless of the races, sexes, ages, positions and occupations. I will do every bit to cure the incurable.I already have a dream in my heart,so I have to make every effort to realize it.As a high school student now,I will seize every chance to study hard,arm myself with knowledge, prepare myself for the future and strive for my dreams. I will be determined, face the reality bravely and not surrender to any problems I meet.Is’s like Gothe says,“The important thing in life is to have a great aim and be determined to attain it.”Being a doctor is my dream. I think it is simple but meanful我的梦想我梦想将来成为一个医生。
我的妈妈是一位白衣天使。
她经常早出晚归，只要医院有需要，她立刻赶去，无论有多晚。
在我小学的时候，我曾经问她，为什么要选择这样一个枯燥无味的工作。
她笑着说，的确有时我也感觉很累，但是看到我的病人慢慢病愈，我从心底高兴。
等到我长大一些，逐渐理解了她的话，也意识到医生有多么的光荣，我下定决心成为一名医生，从那以后，这成为了唯一的理想，至今未变。
我真心希望看到一个没有任何疾病的世界，但是这只是一个幻想。
真实是什么样子的呢
很多人承受着疾病的折磨，很多人生活在一个绝望的困景中，也有很多人被癌症夺走了生命失去了生活在美好世界的机会……这一切的一切让我觉得很伤心，每个生命都是鲜活的。
我想用自己的力量去帮助那些人，减轻他们的痛苦，同时也减轻了我的痛苦。
我想还给他们一个健康的身体，尽自己的努力去拯救更多的人，我更想看到在我的帮助后他们幸福、快乐地与家人生活在一起，所以我想成为一个医生， 一个白衣天使。
I当我成为一个医生，我会尽自己的最大能力去挽救生命，不论各族、性别、年龄、地位……我的内心中的梦想，促使我尽自己的努力去实现它。
现在我是一个中学生，我会好好学习，用知识武装自己，为我的未来和想想做准备。
既然下定决心做，我就会勇敢地面对所有遇到的困难，不畏艰险。
正如，歌德所说“人生中最重要的是树立目标并且义无返顾的实现它”成为一个医生是我的梦想，一个简单而有意思梦想
求翻译，一篇演讲稿译成英文，50悬赏，越快越好啊，谢了
My topic today is to do with a film.First, to quote a sentence from the original film: The Three Stages of Truth 1.Ridicule 2.Violent opposition 3.AcceptanceUp until now, I still cannot watch the whole of the documentary Earthlings. I cannot face the images on the screen; my shock is stronger than the one I got from watching The Cove a few years back.The following contents are partly from the film, and also express some of the feelings in my heart.Scene oneMilking; Cows are tied up in compartments all day, restricted from movement, to improve the milk yield, pesticides and antibiotics are frequently used. Eventually, just like the cow, they are exhausted until collapse.Scene twoTying up a fully conscious baboon, putting a metal helmet on them, and violently hitting the helmet at a 60 degree angle with the force of 1000grams; the purpose of the experiment being simulating the collision of cars. Are these not enough? Is the world not in the progress of a setback of permanent human progression and expansion? For many species, there is no way of escaping. As the saying goes; you reap what you sew.Our health reports clearly show that we have consumed an excessive amount of animals.Cancer, heart disease, osteoporosis, stroke, kidney stones, anaemia, diabetes and many other diseases are all likely to be triggered from this.When animals are suffering, we shrink away; this behaviour is a problem in itself although we try to ignore it. Some people see caring for all beings as being over sentimental, they have over looked an important and beautiful side of human nature; our being kind to animals will not make us suffer a loss in anyway. In fact, we humans are supposed to ensure that animals live a long and happy life.If I can make everyone in the world watch just one film, I would make them see Earthlings.Lastly, to quote that sentence again: The Three Stages of Truth 1.Ridicule 2.Violent opposition 3.AcceptanceP.s. 翻译这段，写着写着心情就好难过。
。
呵呵多愁善感，只是想然你知道 (:
