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。

早餐通常是麦片粥冲牛奶或一杯果汁，涂上黄油的烤面包片，熏咸肉或煎香肠、鸡蛋。
中午，孩子们在学校吃午餐，大人的午餐就在工作地点附近买上一份三明治，就一杯咖啡，打发了事。
只有到周末，英国人的饭桌上才会丰盛一番。
通常主菜是肉类，如烤鸡肉、烤牛肉、烤鱼等。
蔬菜品种繁多，像卷心菜、新鲜豌豆、土豆、胡萝卜等。
蔬菜一般都不再加工，装在盘里，浇上从超市买回的现成调料便食用。
主菜之后总有一道易消化的甜食，如烧煮水果、果料布丁、奶酪、冰激凌等。
鱼和油炸土豆条（Fish and chips） 这是英国民族传统的快餐食品（fast food）。
它是在19世纪60年代流行起来的。
那时，铁路开始把新鲜的鱼一夜间直接（direct）从东海岸运到伦敦。
英国人在鱼上面裹上糊放在油里炸好，和炸土豆条一起吃。
人们把盐和醋的混合调料倒在炸鱼和土豆条上，用报纸包上，然后从纸包里拿着吃。
如今，人们经常用清洁的纸包装，并提供一个餐叉（fork）。
茶（Tea） 英国民族喜欢喝茶。
在英国传统（tradition）上人们用瓷茶杯泡茶，一人一个茶杯，一匙茶。
大多数英国人喜欢喝浓茶，但是要加许多牛奶。
多年前，人们习惯先把牛奶倒入茶杯，然后再放茶，最后加水。
咖啡（Coffee） 现在在英国，咖啡和茶一样受欢迎。
人们或是加牛奶或是不加牛奶，或是喝新泡制的咖啡或速溶咖啡。
酒（Wine） 英国的酒业很强盛。
越来越多的葡萄园正在生产白酒和红酒（red wine）。
英国的酒馆无所不在，有好几万家大大小小各具风味的酒馆，其中还有不乏数百年历史的，这样的老酒馆通常传说闹鬼，有趣的是，主人不但不避讳，还把他家的鬼故事像立传一般摆在每一张桌子上。
有鬼的酒馆生意更好，而且卖得更贵。
饮食习惯用刀叉咯~ 英国人一般较喜爱的烹饪方式有：烩、烧烤、煎和油炸。
对肉类、海鲜、野味的烹调均有独到的方式；然而，他们对牛肉类方面又有特别的偏好，如烧烤牛肉（ROASTED BEEF），在食用时不仅附上时令的蔬菜、烤洋芋，还会在牛排上加上少许的芥茉酱；在佐料的使用上则喜好奶油及酒类；在香料上则喜好肉寇、肉桂等新鲜香料。
较为人知的英国料理菜名有：牛肉腰子派（STEAK KIDNEY PIE）、炸鱼排（ENGLISH FISH CHIP）、皇家奶油鸡（CHICKEN A LA KING）等。
英国人喜欢狩猎，在一年只有一次的狩猎期中，就有许多的饭店或餐厅会推出野味大餐，如野鹿（VENISON）、野兔（HARE）、雉鸡（PHEASANT）、野山羊（WILDSHEEP）等的烹调。
而一般烹调野味时，均采用些杜松子或浆果及酒，此做法是为了去除食物本身的膻腥味。
英国人对早餐非常讲究，英国餐馆中所供应的餐点种类繁多，有果汁、水果、蛋类、肉类、麦粥类、面包、果酱及咖啡等。
时下所流行的下午茶（HIGH TEA）也是传来自于英国，其较知名的有维多莉亚式VICTORIAN STYLE），内容可说是包罗万象，包括各式小点、松糕、水果挞（TARTE）及三明治等。
晚餐对英国人来说也是日常生活中最重要的一部份，他们选择的用餐时间通常较晚，而且都是边吃边喝边聊，以促进用餐人之间的情谊，可想见他们是属于极有自主性的民族，而一顿晚餐对他们来说可能要花上好几个钟头。
在英国当地，会有许多爱好喝的人士，主要是因为它本身也是个产酒国家。
英国人在饮酒上的花费比起其它的支出还来的多。
Nobu餐厅 这是一家享誉全球的日式寿司餐厅，完美诠释了伦敦的多元文化。

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.

And that includes 1,200 mg of calcium and 1,000 mg of vitamin.
求一篇英文的关于麦当劳的演讲稿，内容主要包括起源，发展及对美国人的影响，1000字左右
McDonald's In 1955, a man named Raymond Kroc entered a partnership with two brothers named McDonald. They opened a popular restaurant in Califor-nia which sold food that was easy toprepare and serve quickly. Hamburgers, French fries and cold drinks were the main food there.Kroc opened similar eating places under the same name,McDonald's, and they were an instant success. He later took over the company, and today it is one of the most famous and successful fast-food restaurants in America and the world. Why was his idea so successful? Probably the most important reason was that his timing was right. In the ]950s,most married women stayed home to keep house and take care of their children. In the 1960s, many women returned to the work place. This meant that they had less time and energy for housework and preparation of meals, so they depended more on TV dinners and fast-food restaurants. Single parents also have little time to spend in the kitchen. People living alone also depend on this type of food, since cooking for one is often more trouble than it is worth. Fast-food is not part of all Americans lives. Another trend of the 1960s, sometimes called the back-to-nature movement,influenced many people to avoid food that was packaged and processed. This preference for natural food continues to this day. From the success of Raymond Kroc's fast-food business,we can say that social and economic trends influence where and what we eat. 麦当劳 1955年，一位名为雷蒙德·克劳克的人与两位名为麦当劳的兄弟合伙，在加州开了一家颇受欢迎的小餐馆，销售制作方便服务快捷的食物。
那里的主打食品是汉堡、炸薯条和冷饮。
克劳克用同样的名字—一麦当劳开了几家类似的餐厅，迅速获得了成功。
后来他接管了这个公司，今天它成为美国和世界最有名、最成功的“快餐”厅之一。
他的想法为什么会如此成功呢?也许最重要的原因是因为他时机正好。
20世纪50年代，大多数已婚妇女呆在家里做家务、照顾孩子。
而在60年代，许多妇女回去工作。
这就意味着她们做家务、准备食物的时间、精力减少了，因此她们更多地依赖于“电视晚餐”和快餐店。
单亲家庭中父母也很少有时间花在厨房里。
独自居住的人也依赖于这种食物，因为一个人做饭经常太麻烦，不值当费那功夫。
快餐并不是所有美国人生活的一部分。
20世纪60年代还有另一种有时被成为“返璞归真”运动的趋势，影响了很多人，他们避免食用经过包装和加工的食物。
这种对天然食物的青睐一直持续到今天。
从雷蒙德·克劳克快餐生意的成功中，我们可以说社会和经济趋势会影响我们就餐的地点和食物的选择。

Fish Sticks 鱼条The fish part is usually pollock, rather healthy. The stick part seems to be the remaining 20 ingredients listed on the box, which aren't so healthy. Doctors have been advising people to eat more fish for years, because they are high in healthy fats and low in unhealthy fats compared to beef and pork. Yet when you buy processed fish products or when you order deep-fried fish from a fast-food joint, the bad starts to outweigh the good.鱼条的原材料使用，非常健康。
但是鱼条的烹饪方其含有20种有害成分，似乎么健康。
医生这些年一直建议人们多吃鱼类，因为它们比起牛肉和猪肉，含有更多健康的脂肪和较少的不健康脂肪。
当你购买加工过的鱼肉产品或在速食店里点油炸鱼时，害处立刻大于好处。
Yogurt 优酪乳Armenians in my neighborhood when I was growing up used to make their own yogurt, which is essentially milk fermented with certain bacteria. This is high in protein, calcium and vitamins and can be eaten by adults, who generally cannot digest milk well. What is sold in mainstream U.S. supermarkets under the name yogurt is really a dairy dessert loaded with sugar and processed fruit, disguised as a health food. Try plain, fat-free yogurt and add your own fruit.每当我起床时，我家附近的亚美尼亚人总是在制作他们的优酪乳，其实优酪乳就是含有有益菌的发酵牛奶。
蛋白质、钙和维他命含量丰富，通常给那些牛奶消化不良的成年人食用。
在美国主流超市销售的所谓优酪乳其实是添加糖类和加工过的水果的乳制品甜点，伪装成的健康食品。
尝试纯天然、无脂肪的优酪乳吧，你可以自己添加水果哦。
Canned Soup 罐头浓汤Soup is remarkably healthy, inexpensive and easy to make. A lunch of hardy homemade soup and bread, cooked in bulkand frozen in individual containers for the week, will cost less than a dollar a day. Canned soup, on the other hand, is a miserable concoction of salt, fat, artificial additives, preservatives, water and maybe part of a carrot. One serving typically contains 1,000 milligrams of sodium, about half your daily allowance. Save your chicken and beef bones and vegetable tops and make you own broth.显然，汤很健康，不贵，而且烹饪简单。
辛苦点，自己制作汤和面包当午餐，可以多做点汤，把一周的量分小碗装好放在冰箱，每天花费不到一美元。
罐头浓汤根本就是盐、脂肪、人工添加剂、防腐剂和水的混合物，可能还会有点胡萝卜吧。
一份罐头浓汤基本含有1000毫克的钠，几乎你一天钠摄入量的一半。
把鸡骨头、牛骨、蔬菜叶保存好，自己制作肉汤吧。
Green Tea 绿茶Green tea is widely consumed throughout Asia and is nothing short of an art form in Japan. The tea contains antioxidants and other healthful components shown in clinical studies to possibly prevent cancer, heart disease, senility and other diseases associated with aging. But most Americans don't like the taste, so what you get here is a green tea drink loaded with sugar and other additives, sold under the disguise of a health drink. Any ingredient after the words green tea on the bottle chisels away the health benefits.绿茶在亚洲非常风靡，在日本可谓是一种艺术形式。
根据临床研究表明茶叶内含有抗氧化剂和其它有益成分，可能可以预防癌症、心脏病、衰老和其它与年龄增长有关的疾病。
但是大多数美国人不喜欢这个味道，所以你在这里买到的绿茶饮品中添加了糖份和其它添加剂，还伪装成健康饮品来销售。
任何瓶子上在“绿茶”后的单词都将健康成分给剔除了。
Russet Potatoes 褐色土豆At the risk of pissing off Idaho, the Russet varieties of potatoes, with their brown skin and white flesh, are only marginally healthy to begin with. Cheap and hardy, yes, with a few nutrients, they serve some purpose as a filler. But their starch is quickly converted by the body into blood sugar, called glucose, and raises the risk of diabetes and obesity. And because they are arguably the least flavorful of the hundreds of potato varieties in the Americas, we have to do things to make them tasty. We boil and mash them and cover them in butter, or we cut them into strips, deep-fry them and cover them with salt.褐色土豆品种丰富，皮棕瓤白，本来还和营养食品沾点边，否则它应该早就滚出爱荷华州来吧。
褐色土豆便宜、耐寒，是的，有点营养，它们很管饱。
但是它们内含的淀粉在体内迅速转换成血糖，我们称之为葡萄糖，增加了罹患糖尿病和肥胖症的风险。
也因为它们是在美国几百种土豆中最不可口的那个，我们就需要把它们做的好吃点。
我们将它们煮熟、捣碎，淋上黄油，或是把它们切成条，油炸，撒上盐。
Popcorn 爆米花Popcorn today rarely resembles the healthy treat it used to be. Popcorn is, well, corn. It's high in fiber, low in calories, and contains only nominal traces of sugar, salt and fat. That changes, of course, when you add sugar, salt and fat. Microwave popcorns are the biggest offenders with their long list of ingredients to enhance flavor. Try buying popcorn kernels in bulk for pennies a serving and control the amount of salt and (real) butter. 现在的爆米花已经不像从前那么营养了。
爆米花，没错，是玉米。
玉米是高纤维、低热量，含有少量糖份、盐份和脂肪的食物。
而现在则不同了，当然，你添加了糖、盐和脂肪。
微波炉爆米花为了增加口感而使爆米花含有不少有害成分。
买点爆米花谷粒，分成几份，加入少许盐和（纯）黄油。
Sliced Bread 切片面包The most common form of bread in Americaethe mass-produced white, soft doughy bread in plastic bags with a shelf life of weeks is likely a major component of obesity and diabetes. True bread is flour and water with a pinch of salt and yeast. Packaged white bread contains flour plus sugar, corn syrup and often a dozen other ingredients. The processing creates a food product that, once eaten, is quickly converted to blood sugar, called glucose. This causes the pancreas to work overtime and ultimately destroys the organ. Even mass-produced whole wheat breads are unhealthy because they are made palatable by some evil means: the unholy trinity of sugar, salt and softening additives.在美国最普遍的就是这种大量生产的白色、松软的面包，装在塑料袋中，一周保质期，它就是造成肥胖和糖尿病的主要元凶。
正宗的面包是面粉加水，和少量盐及发酵粉制成的。
包装的白色面包含有有糖面粉、玉米糖浆，通常还添加了其他物质。
这些物质使面包一旦下肚，就迅速转化成为血糖，也就是葡萄糖。
这造成胰腺超负荷运作，最终损伤器官。
甚至是大量生产的全麦面包也不健康，为了使它们可口一些，会使用不健康的方法：添加糖类、盐份和松软剂这三个不良添加剂。
Breakfast Cereal 早餐谷物True cereals---the likes of wheat, barley, rice and oats, to name a few---are and have always been the most important food of the human race. The combination of protein, healthy fat and vitamins is unbeatable. The word cereal has been hijacked, however, by food producers who make tiny, crunchy breakfast cakes out of true cereal with the addition of sugar, corn syrup, salt, food dyes and preservatives. Try oats with raisins, or barley with 100-percent fruit spread. These are far healthier and far cheaper. 真正的谷物--像小麦、大麦、稻米和燕麦等等--对于人类来说是非常重要的食物。
它们富含了很多蛋白质、健康的脂肪和维他命。
然而“谷物”这个词被食品制造商给滥用了，他们用谷物添加糖份、玉米糖浆、盐份、食用色素和防腐剂生产出小型、松软的早餐蛋糕。
尝试用燕麦加上葡萄干，或者百分百纯果酱自制早餐。
它们肯定更健康、更便宜。
Commercial Organic 有机商品It started as a brilliant idea. Dedicated farmers would become stewards of the land, shunning the toxic chemical pesticides and fertilizers that had proliferated after WWII. They would raise food naturally, cultivate diverse crop varieties native to their soils. Animals raised for food would be treated with care and dignity. And for 30-some years, this has been the case. But organic food is so popular that its value system is in jeopardy. Big players such as Wal-Mart and Kraft want part of the profits, and their demand for cheaper production methods undermines what it means to be organic. And so we now have organic milk from caged cows force-fed organic grain. And we have organic junk food with organic ingredients flown in from around the globe, disguised as health food by virtue of the organic label.这个主意挺聪明的。
这样农民就可以变成陆上乘务员，避开在二战后开始使用的有毒化学杀虫剂和肥料。
植物会自然生长，根据自身土壤培育出各种各样的农作物。
那些用来食用的动物也会得到很好的照料。
三十年来，一直如此。
但是有机食品很受欢迎，它的价值体系也岌岌可危。
像沃尔玛和卡夫这样的大公司希望分得一杯羹，他们采用更便宜的生产方式，破坏了有机的含义。
所以我们现在喝的有机牛奶出自那些食用有机谷物长大的圈养奶牛。
我们吃着含有有机成分的有机垃圾食品，而因为它贴上有机标志，就伪装成为健康食品。
Pizza 比萨What a pity that most Americans have never eaten pizza and confuse it for the junk food advertised on television. In Italy there are laws defining pizza, which set allowances on the type of flour, tomato, mozzarella, olive oil, basil and oregano. Pizza is inherently nutritious and filling. Street corner pizza shops in Philadelphia, New York and other large cities kept close to the original idea of simple, fresh ingredients. Then came the pizza chains, which put most local shops out of business. Fresh ingredients were replaced with preservative-laden, cheap and fatty ingredients that could be mass-produced, frozen and shipped across the country. Commercial pizza is now a high-calorie, high-fat, high-sodium, low-nutrient food.多么可怜啊，大多数美国人从来没有吃过比萨，还把它和电视上广告的垃圾食品搞混。
在意大利，有关于定义比萨的法律，规定比萨由面粉、番茄、意大利干酪、橄榄油、罗勒和牛至制成。
比萨本身其实含有营养，而且管饱。
在费城、纽约和其它大型城市街角的比萨店保留了简单、新鲜的比萨制作方法。
之后出现了比萨连锁店，使得许多当地商店破产。
新鲜的食材被添加防腐剂、廉价和脂肪多多的材料所替代，这样就可以在大量生产、冷藏，运往全国各地。
比萨商品时一个高卡路里、高脂肪、高钠和低营养的食物。
