晚餐摄入不当，很容易导致多种疾病

晚餐摄入不当，很容易导致多种疾病

越来越多的科研成果表明，危害人类健康的高血脂、心血管疾病、糖尿病、肥胖症以及癌症等，部分与饮食不当有关。特别是晚餐摄入不当，很容易导致多种疾病，最常见的疾病有以下八种。
肥胖症
晚餐过饱，血中糖、氨基酸、脂肪酸浓度就会增高，再加之晚上人们活动量小，热量消耗少，多余的热量在胰岛素的作用下合成脂肪，逐渐使人发胖。
　　

高血脂、高血压症
大量的临床医学和研究资料证实，晚餐经常进食荤食的人比经常进食素食的人血脂要高3～4 倍。而患高血脂、高血压的人，如果晚餐经常进食荤食，等于火上加油，使病情加重或恶化。

糖尿病
中老年人如果长期晚餐过饱，反复刺激胰岛素大量分泌，往往造成胰岛素B 细胞负担加重，进而衰竭，诱发糖尿病。

冠心病
晚餐经常摄入过多热量，可引起血胆固醇增高，过多的胆固醇堆积在血管壁上，久而久之就会诱发动脉硬化和冠心病。

急性胰腺炎
如果晚餐暴饮暴食，容易诱发急性胰腺炎，使人在睡眠中休克，若抢救不及时，往往危及生命。如果胆道有结石嵌顿、蛔虫梗阻、慢性感染等，则更容易诱发急性胰腺炎而猝死。

肠癌
晚餐过饱，必然有部分蛋白质不能被消化吸收，这些物质在肠道细菌的作用下，产生一种有毒有害的物质，再加之睡眠时肠壁蠕动减慢，相对延长了这些物质在肠道的停留时间，促进大肠癌的发生。

尿道结石
研究认为，尿道结石与晚餐太晚有关。这是因为尿道结石的主要成分是钙，而食物中含的钙除一部分被肠壁吸收外，大部分排出体外。据测定，人体排尿高峰一般在饭后4～5小时，如果晚餐过晚，排尿高峰期人处于睡眠状态，尿液全部潴留在尿道中，久而久之就会形成尿道结石。

神经衰弱
晚餐过饱，必然造成胃肠负担加重，紧张工作的信息不断传向大脑，使人失眠、多梦等，久之易引起神经衰弱等疾病。

毛泽东与邵华：劝儿媳多读《上邪》(

毛泽东与邵华：劝儿媳多读《上邪》

本文网址：http://www.backchina.com/news/2009/3/25/34334.html

　　
邵华和刘思齐是同母异父的姐妹，就像贺子珍和贺怡姐妹俩嫁给毛泽东和毛泽民兄弟俩一样，刘思齐和邵华姐妹俩嫁给了毛岸英和毛岸青兄弟俩。

　　　　

毛泽东和邵华谈论文学　　

邵华原名张少华，父亲陈振亚原是彭德怀部属的一个连长。1937年冬天，陈振亚和张文秋结婚，当时张文秋带着一个小女儿，她就是刘思齐。 1938年秋，张文秋生下一个女孩，陈振亚给女儿取乳名“安安”，学名随母姓叫张少华(即邵华)。后来在迪化(乌鲁木齐)陈振亚和毛泽民等革命者一起被盛世才残害。不久，张文秋生下了遗腹子第三个女儿少林。　　新中国成立不久，姐姐刘思齐和毛岸英结婚了，几乎每个周末都要去中南海看望父亲毛泽东。11岁的邵华总是吵着要一起去见毛主席。

　　

1959年，邵华考进了北京大学中文系。博览群书的毛泽东非常关心她的读书情况，和她在文学上成了“论友”。在谈到曹操父子时，毛泽东说：“我喜欢曹操的诗。曹操的诗词，直抒胸臆，豁达洒脱，应当学习。比如他的《龟虽寿》、《短歌行》、《观沧海》等篇章，更是脍炙人口。”　　毛泽东非常推崇李白，认为李白的诗“文采奇异，气势磅礴，有脱俗之风。”在评论白居易时，他说：《琵琶行》不但文采好，描写得逼真细腻，难得的是作家对琵琶演奏者的态度是平等的，白诗的高明处在于此而不在他。同时，毛泽东还谈到了王昌龄、陆游、辛弃疾这些人的边塞诗，并把王昌龄的《从军行》等亲笔写给在座的儿女们。　　

在谈到“初唐四杰”之一的王勃时，毛泽东说：这个人年轻有为，才高学博，为文光昌流丽，二十几岁的人就写了十六卷诗文作品，可惜死得太早了。他还说他喜欢王勃的《送杜少府之任蜀州》，对其中的“海内存知己，天涯若比邻”两句很欣赏。交谈中，当毛泽东发现邵华这些孩子也十分喜欢王勃的《滕王阁序》，非常高兴，在谈到兴头时，又挥笔写下了“落霞与孤鹜齐飞，秋水共长天一色”的千古名句。　　

在谈论《西游记》时，毛泽东对孙悟空不畏艰险、敢于同一切妖魔鬼怪作斗争的精神和善于识别正义和邪恶的洞察力，以及不达目的决不罢休的可贵品格和顽强毅力十分称赞。　　当谈到《聊斋志异》时，毛泽东认为《小谢》是一篇好文章，反映了个性解放的强烈要求，并说《聊斋志异》中那些善良的“狐仙”要多些就好了。　　

许多人都认为毛泽东对中国文学可谓是烂熟于心，但对于外国文学似乎没有什么兴趣和研究。但邵华却觉得并非如此，她和毛主席就谈过《简·爱》。而且毛泽东在听说后就立即找来看了。在解放初期，毛泽东还曾托刘思齐借了一本《茶花女》，毛泽东认真阅读后，还在上面圈圈点点，作了许多眉批。刘思齐当时看到后大吃一惊，因为书是借来的。等后来知道有了毛主席的批阅这才更珍贵时，这本《茶花女》已经丢失，好不遗憾。　　　

劝儿媳多读《上邪》　　1960年，37岁的毛岸青和邵华在大连结婚。　　谁家没有一本难念的经呢？毛泽东家也不例外。而毛岸青和邵华的婚后生活自然总有一些不如意的事情发生。再加上岸青的精神不能经受一点刺激，小夫妻之间自然而然就不可避免地发一些小脾气。　　对这一切，毛泽东十分理解邵华。毛泽东于1962年5月2日离京南下，7月6日才回到北京。在接到毛岸青和邵华两人要分别给他写信的消息后，匆匆行程中的毛泽东在6月3日上午7时给邵华回了一封信——　　你好！有信。拿来，想看。要好生养病，立志奔前程，女儿气要少些，加一点男儿气，为社会做一番事业，企予望之。《上邪》一篇，要多读。余不尽。　　父亲　　六月三日上午七时　　令人奇怪的是，这封家书毛泽东没有写抬头，这也是毛泽东家书中惟一没有抬头的信件。家书中，毛泽东首先劝慰儿媳邵华“要好生养病，立志奔前程 ”，而且“女儿气要少些，加一点男儿气”，希望邵华勇敢地面对生活中、学习上暂时的困难和挫折，要有一股不服输、不怕苦和战胜困难的精神，要有“谁说女子不如男”的英雄气，只有这样才能“为社会做一番事业”，这是毛泽东所“企予望之”的。“《上邪》一篇，要多读。”七个字，笔力千钧，意味深长。　　《上邪》乃汉朝民歌《饶歌》第十六曲。“邪”即“耶”。全词为：“上邪！我欲与君相知，长命无绝衰。山无陵，江水为竭，冬雷震震，夏雨雪，天地合，乃敢与君绝！”　　这是一个女子对爱人的山盟海誓。意思是说：“苍天啊！我对你发誓，我和我的爱人相亲相爱，我们的爱情永远没有断绝的时候！只有到了山夷为平地，江水干枯，冬天雷声阵阵，夏天雨雪纷纷，天地合而为一的时候，我才敢决定与您断绝关系！”诗中列举了五种不可能出现的自然现象，来比喻女子对爱情的忠贞不渝和坚定不移。　　

毛泽东以其渊博的学识巧妙地告诉儿媳一个做人处世的道理，鼓励并希望邵华坚强些，既要以事业为重，又要坚信美好的爱情可以成为战胜生活中的困难、家庭中的纠葛和烦恼的武器。毛泽东可谓用心良苦。　　

毛泽东让儿媳“要多读”《上邪》，邵华理解了父亲这封家书的用心和意义。此后，邵华的性格慢慢地变得开朗了、豁达了、从容了，对岸青也更加关心和体贴了。“与君相知”的她没有辜负毛泽东的“企予望之”，与毛岸青患难与共。(《北京晚报》7.6)

You Need Some R&R

You Need Some R&R

One of the most crucial aspects of a well-designed fitness plan is rest. Not only does it help your muscles recover from your workout, relaxation also gives your mind a much-needed break. When you relax, you turn on your parasympathetic nervous system (PNS). This nervous system is the opposite of the sympathetic nervous system (SNS), which governs your actions during the typical week. All too often we spend most of the work week in a state of agitation, with our fight-or-flight response – a function of the SNS – in full-on battle mode. You must turn off your SNS and turn on your PNS from time to time. If you don’t, you’re headed for burnout. You’ll feel irritable and fatigued. And when you’re tired, you won’t want to exercise. So in a whacky way, allowing yourself periods of rest will actually help you stick to your workouts. You may feel guilty relaxing at first, but when such thoughts pop into your head, just use the oops technique. Say “oops” out loud, and then return to lounging in your hammock.

吃得过饱、喜欢饮酒、容易兴奋是诱发猝死的原因

按1992年维多利亚会议提出的健康四基石:合理膳食，戒烟限酒，适当运动，心理平衡。四基石的效果:1996年美国疾病控制中心指出，采用健康四基石为健康生活方式，可使美国人平均寿命延长10年，高血压下降55%，脑卒中下降75%，肿瘤下降1/3，糖尿病下降50%，冠心病事件明显减少，生活质量明显提高。

一般吃得过饱、喜欢饮酒、容易兴奋三个特征是诱发猝死的三个原因。此外还应注意“三个半分钟”:夜间睡醒时先在床上躺半分钟;然后再坐起，坐半分钟;然后再转到床边，两脚下垂半分钟。注意“三个半小时”:早晨行走半小时;中午最多睡半小时;傍晚行走半小时。心理平衡“三个正确”:正确对待自己;正确对待他人;正确对待社会。

10 Ways to Lower Your Cholesterol Naturally

10 Ways to Lower Your Cholesterol Naturally
Thursday, March 19, 2009

What’s the nation’s No. 1 killer? Heart disease. It causes one death every 35 seconds. So protect your heart with these 10 tips to reduce cholesterol from Janet Bond Brill, a registered dietitian and author of Cholesterol Down (Three Rivers Press). Plus, test your heart attack risk...
Cholesterol and Heart DiseaseWhat’s cholesterol? It’s a type of lipid or fat. In our bodies, it travels through our blood stream in particles called lipoproteins. Low-density lipoproteins (LDL) are bad cholesterol because they can lead to a buildup of plaque in arteries.
A mass of plaque can narrow your arteries and restrict blood flow – much like trying to sip juice through a clogged straw. Eventually, the plaque ruptures and a blood clot forms, cutting off the flow of blood, oxygen and nutrients to the brain.
Hello, heart attack and stroke!
High-density lipoproteins (HDL), on the other hand, are good cholesterol because they pick up the LDL clogging your arteries and take it to the liver, where it’s processed and eventually excreted.
Chow Down“Lowering your cholesterol reduces your risk of contracting heart disease and dying from a heart attack,” Brill says.
What you eat can affect the amounts of HDL and LDL flowing through your bloodstream, and Brill has a cholesterol-lowering eating plan that’s tasty and effective.
“My diet is about what you can eat – not what you can’t” she says.
What’s on her list? Try these 8 super-foods:
(Aim to eat all eight daily, and heed the two bonus tips as well. If you follow only half the steps, you’ll only get half the benefits.)

1. OatmealOats are rich in beta-glucan, a soluble fiber that acts like a sponge to soak up cholesterol.
How to sneak it in: Add cinnamon or dried cranberries to your morning oatmeal for a flavor boost. Oat-bran is a highly concentrated source of beta-glucan, and it’s easy to mix into homemade bread, muffin and pancake batter.
Brill’s daily Rx: 3 grams of beta-glucan, found in a half cup of dry oatmeal or oat bran.

2. AlmondsAlmonds contain two powerful antioxidants – vitamin E and flavonoids – which prevent the oxidation of LDL, a precursor to plaque buildup.
How to sneak it in: Eat almonds with their skins, which pack a hefty dose of flavonoids. Stir a handful into yogurt or spread two tablespoons of almond butter on whole-wheat bread.
Brill’s daily Rx: One ounce of dry-roasted, unsalted almonds.

3. FlaxseedsFlaxseeds contain lignan and soluble fiber, which block the production of LDL and increase your body’s ability to get rid of cholesterol.
How to sneak it in: Eat ground flaxseeds rather than whole ones, because your body can better absorb its nutrients. Brill likes to sprinkle them in her morning bowl of oatmeal.
Brill’s daily Rx: 2 tablespoons of ground flaxseeds.

4. GarlicGarlic impedes the liver’s ability to make cholesterol.
How to sneak it in: Chop garlic into small pieces to release its flavor. Sauté it with steamed spinach, add it to sauces and soups or purée roasted garlic with cooked potatoes and olive oil for a heart-healthy version of everybody’s favorite: mashed potatoes.
Brill’s daily Rx: One clove and one Kyolic One Per Day Cardiovascular aged garlic extract supplement.

5. Phytosterol-Containing FoodsPhytosterols are a fat found in plant foods such as fruits, nuts, seeds and vegetable oils. They interfere with cholesterol absorption by blocking it from your intestinal cells.
How to sneak it in: Even a vegetarian diet provides no more than 300 to 400 mg of plant sterols a day, well below Brill’s recommendation. Supplement this with foods containing added phytosterols – chocolate bars, margarine, cheese, granola bars and cookies, to name a few – but keep an eye on saturated fat and trans-fat content.
Brill’s daily Rx: 2 to 3 grams of phytosterols a day spread over two meals.

6. ApplesApples, particularly the skin and outer flesh, are rich in polyphenols, powerful antioxidants that help prevent plaque buildup.
How to sneak it in: Chop, slice or dice ’em, but leave the peel on for maximum health benefits.
Brill’s daily Rx: One apple a day – to keep the doctor away, of course.

7. BeansBeans contain a special type of soluble fiber that’s fermented in the colon. Healthy bacteria eat the fiber and bean sugars to form short-chain fatty acids, which travel to the liver and hinder LDL cholesterol production.
How to sneak it in: Brill loves Adzuki beans, which are used in Japan to make sweet red bean paste. She also recommends cannelloni beans (try them in Tuscan soups, a type of Italian bean-based soup) and kidney beans, perfect in Southwestern chili.
Brill’s daily Rx: 1/2 cup of legumes (beans, peas or lentils).

8. Soy ProteinSoy protein contains phytoestrogens – compounds that increase the number and effectiveness of LDL cholesterol receptors, improving the liver’s ability to get rid of cholesterol in your bloodstream.
How to sneak it in: Order a soy latte at your favorite coffeehouse, throw tofu into a fruit smoothie, use soy flour when baking, or mix a handful of roasted soy nuts with dried fruit for an energy-boosting trail mix.
Brill’s daily Rx: 20–25 grams.
Diet isn’t your only defense against cholesterol.
“Every step works to lower cholesterol in a specific way,” Brill says. “By combining them all, you get an extremely powerful LDL-lowering multi-pronged approach.”
Here are two of her favorite non-food-related tips:

9. Take Metamucil (Psyllium Husk)Metamucil contains psyllium husk, a fiber that blocks cholesterol from entering your intestinal cells. It’s “the most powerful LDL-lowering viscous soluble fiber in existence,” Brill says. This fiber soaks up cholesterol so you excrete it rather than absorb it into your intestinal cells.
How to sneak it in: Adults should consume 10 to 25 grams of soluble fiber a day, advises the National Cholesterol Education Program, but most get only 3 to 4 grams.
Brill says you should get half your fiber from a supplement and the rest from food. Take half your daily dose of Metamucil before breakfast and half after dinner to avoid overloading your body on fiber, which can cause gas, constipation or even diarrhea.
Brill’s daily Rx: Work up to 12 capsules a day, for a total of 6 grams of psyllium husk.
Or use the powdered version, which you can mix into water. It varies by product, but most Metamucil powders contain 3.4 grams of psyllium husk per serving.

10. Work Up a SweatBrisk exercise speeds up blood flow in your arteries, reducing your chances of inflammation and clogging (two precursors to hardening of your arteries).
How to sneak it in: You don’t have to hit the gym to get some exercise. Clip on a pedometer while you run errands and aim for 10,000 steps a day.
Brill’s daily Rx: 30 minutes of exercise.
Each of the foods and tips mentioned play a crucial role in lowering your cholesterol and keeping your body healthy.

14个确有科学依据的长寿迹象

来源：生命时报 　

　　也许你并不知道，一些平时看似不重要的生活习惯，或是你曾经的生活环境，都会影响你的寿命。美国《预防》杂志3月13日刊文列出了14个确有科学依据的长寿迹象。
　　1。出生时母亲还年轻。美国芝加哥大学科学家研究发现，一个人出生时母亲年龄如果不到25岁，他们活到100岁的几率是出生时母亲超过25岁的人的两倍。
　　2。爱喝茶。一项针对4.05万名日本男女的研究结果显示，每天喝至少5杯茶的人，他们死于心脏病和中风的几率最低。
　　3。每天步行30分钟。一项针对2603名男女的最新研究结果表明，每天坚持步行30分钟左右的人，不管其体内脂肪含量有多高，他们的长寿几率是那些每天步行少于30分钟的人的4倍。
　　4。少喝碳酸饮料。美国科学家发现，每天喝一次以上可乐会使你患心脏病、糖尿病等病的风险加倍。倘若实在想喝几口碳酸饮料，可以在里面加入一些果汁。
　　5。腿部健壮。“腿部肌肉力量差预示着步入老年后身体虚弱。”腿部健壮尤其能预防髋骨骨折，由于髋骨骨折会引发各类并发症，多达20%的患者会在一年内去世。
　　6。吃紫色食物。一项最新研究显示，紫葡萄、蓝莓和红葡萄酒富含多酚，可降低罹患心脏病的几率，预防老年痴呆症。
　　7。青少年时体重正常。研究人员针对137名美国黑人进行研究，对他们从出生到28岁做了跟踪调查，结果发现，14岁时体重超重会增加成年时患2型糖尿病的几率。
　　8。少吃红肉。美国癌症研究院的一份报告称，如果每周摄入的红肉超过510克，会提高患结直肠癌的风险。每天摄入99克经过加工的肉类食品(例如熏肉和熟食)，患结直肠癌风险将提高42%。
　　9。上过大学。哈佛大学医学院一项研究发现，正规受教育时间超过12年的人，比受教育时间相对较少的人寿命长18个月。
　　10。人缘好。“良好的人际关系是应对紧张的缓冲器。”长期精神紧张会削弱免疫系统并加速细胞老化，最终让寿命缩短4到8年。
　　11。朋友身体健康。如果好友体重增加，同样事情发生在你身上的可能性将提高57%。
　　12。自制力强。相对于责任感不强的人来说，那些自认为自我约束能力强、做事有条理的成功人士更加长寿。
　　13。不请保姆。根据一项有302名年龄七八十岁的老年人参加的研究，使用吸尘器、清扫楼梯或擦窗户的时间在一小时以上，便可让一般的人燃烧大约285卡路里热量，同时将死亡的危险降低30%。
　　14。性格活跃。刊登于《心理学家》杂志的一项研究称，有大约17%的美国人性格比较活跃，这些人比沉闷的人更为健康。▲ (杨孝文)

男人一辈子的不老法则

男人一辈子的不老法则
佚名

　通常情况下，男人最初的衰老是在20-22岁身体发育完全成熟时开始的。不过，不必为此感到抑郁和恐慌。专家研究证实，人的寿命完全可能达到110岁，要想延缓衰老，男人必须了解自己在不同年龄段的生理特征，有针对性地采取各种保健方法。
　　20-30岁：少吃甜食，少量饮酒，少吸香烟
　　这一年龄段，男人的身体新陈代谢开始放慢，甜食由于含热量过高，容易转化成脂肪堆积在腹部，最好是少吃或戒掉。由于这一年龄段的男人正是干事业、交朋友的大好时机，平时娱乐、喝酒的机会较多，因此要注意少喝酒。酒能使人增加患肝癌、口腔癌和喉头癌的可能性，酒还能使血压升高，导致患心脏病或心肌梗死。过量地饮酒还会影响性生活的质量，而大量的酒精更会对人体精子造成损害。
　　不要抽烟，抽烟会使你平均减少10年寿命。由于吸烟会增加心血管病、肺癌和呼吸器官疾病的危险，因此，这一年龄段的男人最好戒烟，如一时戒不了，应多吃胡萝卜、葱蒜、菠菜和橙黄色的水果，多吃鱼类，经常喝茶等以减轻烟害。要经常锻炼身体，可以时常做做深呼吸，其好处会慢慢体现出来。为延缓肌肉衰老，只能多做运动。但运动项目的选择颇有学问，只有那些更像娱乐的运动而不是高强度的训练才对此有帮助，否则将会适得其反。这些运动既可促进体内多余热量的燃烧，又可维持正常的物质代谢。如果此时不加紧时间锻炼身体，70岁时体能就会下降三分之二。
　　这一年龄段正是成家立业的最佳时机。据统计，结婚有偶者的早死率比独身、丧偶和离异者低。要选择好自己最适合的职业，合适的职业对寿命有着巨大影响。
　　30-40岁：劳逸结合，防止噪音，护好皮肤
　　进入而立之年，皮肤开始松弛，眼睛周围开始出现皱纹。这时应该少晒太阳，经常涂抹润肤霜，以防止皮肤干燥。
　　这一年龄的男子所面临的另一个问题是听觉下降，这是工作和生活环境中的噪音造成的。如果你是音乐发烧友，就少听一些重金属音乐，在噪音比较大的岗位上工作一定要戴上耳塞。
　　
血液中胆固醇的含量会随年龄而升高，堵塞血管的低密度脂类物质也不断增加，而有助废物排泄的高密度脂蛋白却在减少。因此，注意饮食便显得尤为重要，切忌暴饮暴食。为增加高密度脂蛋白的含量，宜进食较为清淡的食物。要控制脂肪，构成每天能量的脂肪摄入量不得超过30%，但不得少于15%。
　　专家建议，这一年龄段的男性应该着手预防肾脏疾病，每天喝8到10杯清水。35岁后，男人的小腹很容易凸起，体育活动时千万不能三天打鱼，两天晒网。
　　成年男子诸事繁杂，情绪紧张已对进食量有所影响，如果不按时定量进餐而时常过饥过饱，可能使肠胃受损而影响情绪与睡眠，而情绪与睡眠较差又会影响进食，从而形成恶性循环。在此种情况下多感疲惫不堪，自然又会影响性生活的和谐。当劳累与紧张时，很可能出现头晕气短、精神涣散的现象，身体较弱者尤是如此。所以，在饮食中应有意识地多吃些富含蛋白质的食物如牛奶、鸡蛋等，并注意均衡摄取多种营养素，才可使体内营养充足而精力充沛。
　　40-50岁：活动双目，勤查身体，放松肌肉
　　这一时期最令人头疼的问题是视力下降。糖尿病是导致失明的最常见病因，它会逐步损伤人体血管，甚至眼部。所以，应定期去医院眼科做检查。同样，有这种危险的还有各种心血管疾病患者。平时不妨多做一些眼部练习，可以上下左右慢慢转动眼球或是伸出手臂，用大拇指在身体前画8字，目光跟随拇指移动。每天花15分钟做这些练习，能够有效预防老花眼和白内障。
　　许多男性会感到自己的性需求减退，其实这很正常，将目光转到提高性生活质量上去。
　　繁忙的工作令人神经紧绷，利用简单肌肉松弛法，以达到全身松弛状态。方法如下：找个地方坐下，快速地拉紧身体某一块肌肉持续5秒钟，然后再慢慢放松。反复进行肌肉收紧、放松动作，从头、眼睛到脚趾，全身肌肉都可以进行。
　　改变几年都不去医院的坏习惯。许多男人不爱去看医生，据统计，有80%的重病患者承认，自己是长期不去医院，小病误成大病，等到心脏病、脑溢血等病发作时才不得不去医院，贻误了最佳治疗时机。故每年例行体检是保持健康的最好方法。
　　50-60岁：注意牙齿，锻炼肌肉，多用大脑
　　医学研究表明，人体内的胆固醇含量在50岁以后就会停滞，尽量少吃奶油面包等高热量食品，因为这一年龄段常容易长肉。人体免疫系统的机能会有很大退步，较以往更容易感染各种疾病，身体恢复同样需要更多的时间。这就要求人们在选择食物时宜以富含维生素C、E和胡萝卜食物为主，因为它们有利于调节体内化学反应的平衡。
　　口腔保健也很重要，此时常会发生牙龈萎缩。脸部也容易发福，出现双下巴，不妨做一些面部按摩。当然，这个年龄的男性最易患的毛病在于人体肌肉的减少，易引起排尿困难。同时，这一时期面临的主要问题是身体消瘦，也许这正是胖人们求之不得的，但这并不是个好兆头。体重的下降来自于人体肌肉的减少，肌肉在人体内所占的比重大于脂肪。在这一年龄，体重减轻是人体衰老的危险信号。肩部和手臂处的皮肤松弛得最厉害，需要定期锻炼肌肉。
　　男性的身高也会有所下降，大约是每20年缩1.5厘米左右。同时，头发的光泽也会逐渐黯淡，可以采用一些富含营养物质的护发素。不过，千万别忘记锻炼大脑，平时多看书报杂志，做做智力题即可。
　　60-70岁：善待人生，增强体力，健康饮食
　　这一年龄段的男性，其外表特征将会发生明显的改变：皮肤更为粗糙，开始出现大小不等的老年斑；鼻子显得更长更宽，耳垂多肉。睡眠的减少可能无助于体能的恢复，人的记忆力也会变得越发糟糕。腿和腰自然会衰老。腿的力量一旦减弱，人就容易跌倒，甚至导致一辈子卧床不起。
　　在进行体育锻炼时，每天坚持一刻钟，主要进行屈膝、伸直的动作，并且坚持每天到户外散步、做做广播体操等。此时最重要的是保持乐观的心境和健康的体魄，不让外表的变化影响情绪，要保持平静心态，情绪乐观。同时，为防止各种癌症的发生，应多食用具有防癌作用的食物，例如：新鲜蔬果，尤其是菠菜、番茄、芹菜、苹果、枣子、柑橘、菠萝、豌豆、豆芽菜、瓜、胡萝卜等；含有多糖体之植物，香菇、草菇、木耳、银耳、猴头菇、洋菇等；海产品为最好的防癌食物，宜多吃海参、海带、紫菜、蛤蚌、乌贼、鱿鱼、淡菜、虾、海蜇皮、鲍鱼等，这些均有抗癌、防癌效果；含有微量金属元素之食品有：蛋、芝麻、肝、肾、啤酒酵母、麦芽、荸荠、薏仁、菱角、百合、山药、茶叶等。
　　虽然上述食物皆有防癌、抗癌之效，但天天食用，反而会摄取过量，须全面均衡饮食及不偏食，如此才能达到防癌作用。要尽量少吃些油腻和油炸食物，多吃植物油，少吃动物油，平时多吃些蒜和鱼类，适量喝点红葡萄酒，这些做法能降低胆固醇含量。

Balanced diet

Chicken, beef, potatoes, pasta, cereal, salad. With an endless array of food options out there, how do you know what to eat for a balanced diet? It’s easier than you think! Let me simplify it for you. You should eat a combination of three macronutrients: protein, carbohydrate and fat. All of these nutrients help keep your body in tip-top shape. Aim to get about 40% of your calories from protein, 40% from carbohydrates and 20% from fat. You don’t have to divide every meal so specifically, but when you tally up your caloric budget at day’s end, you should be as close to a 40/40/20 ratio as possible. And be sure to eat the good types of fat: unsaturated and omega-3 fats. Unsaturated fats are found in olive, sunflower and other oils, and omega-3 fatty acids are found in flaxseed products, fatty cold water fish such as salmon and tuna, avocados, nuts, seeds, almonds, and soybeans.

Cancer prevention: 7 steps to reduce your risk

Cancer prevention: 7 steps to reduce your risk

Small changes in your everyday life might help reduce your risk of cancer.
You've probably heard conflicting reports in the news about what can or can't help you in terms of cancer prevention. The issue of cancer prevention gets confusing — sometimes what's recommended in one report is advised against in another. What you can be sure of when it comes to cancer prevention is that making small changes to your everyday life might help reduce your chances of getting cancer. Try these seven cancer prevention steps.

Cancer prevention step 1: Don't use tobacco

All types of tobacco put you on a collision course with cancer. Rejecting tobacco, or deciding to stop using it, is one of the most important health decisions you can make. It's also an important part of cancer prevention.
Smoking has been linked to several types of cancer, including:
Bladder
Cervix
Esophagus
Kidney
Lip
Lung
Mouth
Pancreas
Throat
Voice box (larynx)
Chewing tobacco has been linked to multiple types of cancer, including:
Esophagus
Mouth
Pancreas
Throat
Inhaled chewing tobacco (snuff) may increase the risk of cancers, including:
Esophagus
Mouth
Even if you don't smoke, avoid exposure to secondhand smoke. Being around others who are smoking may increase your risk of lung cancer.

Cancer prevention step 2: Eat a variety of healthy foods

Though making healthy selections at the grocery store and at mealtime can't guarantee you won't get cancer, it may help reduce your risk.
The American Cancer Society recommends that you:
Eat an abundance of foods from plant-based sources. Eat five or more servings of fruits and vegetables each day. In addition, eat other foods from plant sources, such as whole grains and beans, several times a day. Replacing high-calorie foods in your diet with fruits and vegetables may help you lose weight or maintain your weight. A diet high in fruits and vegetables has been linked to a reduced risk of cancers of the colon, esophagus, lung and stomach.
Limit fat. Eat lighter and leaner by choosing fewer high-fat foods, particularly those from animal sources. High-fat diets tend to be higher in calories and may increase the risk of overweight or obesity, which can, in turn, increase cancer risk.
Drink alcohol in moderation, if at all. Your risk of cancers, including mouth, throat, esophagus, kidney, liver and breast cancers, increases with the amount of alcohol you drink and the length of time you've been drinking regularly. Even a moderate amount of drinking — two drinks a day if you're a man or one drink a day if you're a woman, and one drink a day regardless of your sex if you're over 65 — may increase your risk.

Cancer prevention step 3: Stay active and maintain a healthy weight

Maintaining a healthy weight and exercising regularly also may play a role in cancer prevention. Being overweight or obese may increase your risk of cancers of the breast, colon, esophagus, kidney, stomach and uterus. Physical activity can help you avoid obesity by controlling your weight. Physical activity on its own may also lower your risk of cancers of the breast, colon, prostate and uterus.
Try to be physically active for 30 minutes or more on most days of the week. Once you achieve that goal, adding more exercise to your day may reduce your risk of certain cancers further.
Your exercise sessions can include such low-key activities as brisk walking, raking the yard or even ballroom dancing. Safe exercise programs are available for just about everyone. Your doctor or physical therapist can help design one for you.

Cancer prevention step 4: Protect yourself from the sun

Skin cancer is one of the most common kinds of cancer — and one of the most preventable. Although repeated exposure to X-rays or contact with certain chemicals can play a role, sun exposure is by far the most common cause of skin cancer.
Most skin cancer occurs on exposed parts of your body, including your face, hands, forearms and ears. Nearly all skin cancer is treatable if you detect it early, but it's better to prevent it in the first place. Try these tips:
Avoid peak radiation hours. The sun's ultraviolet (UV) radiation peaks between 10 a.m. and 4 p.m. Minimize or avoid being outside during these hours.
Stay in the shade. If you go outside, minimize your sun exposure by staying in the shade.
Cover exposed areas. Wear light-colored, loosefitting clothing that protects you from the sun's rays. Use tightly woven fabrics that cover your arms and legs, and wear a broad-brimmed hat that covers your head and ears.
Don't skimp on sunscreen. Use a broad-spectrum sunscreen that has a sun protection factor (SPF) of at least 15.
Don't use indoor tanning beds or sunlamps. These also can damage your skin. There's no such thing as a healthy tan.

Cancer prevention step 5: Get immunized

Certain cancers are associated with viral infections that can be prevented with immunizations. Talk to your doctor about immunization against:
Hepatitis B. Hepatitis B can increase your risk of developing liver cancer. Vaccination is recommended for all babies in the United States. Certain high-risk adults also may need to be vaccinated.
Human papillomavirus (HPV). HPV is a sexually transmitted virus that can lead to cervical cancer. The vaccine that protects against two cancer-causing types of HPV is recommended for girls ages 11 to 12. In addition, the Centers for Disease Control and Prevention recommends that the HPV vaccine be given to girls and women ages 13 to 26 who haven't completed the full vaccine series.
Talk to your doctor about whether you would benefit from immunizations to reduce your risk of cancer.

Cancer prevention step 6: Avoid risky behaviors

Reduce your risk of certain cancers by avoiding risky behaviors that can lead to infections that may increase your risk of cancer. Viruses transmitted sexually or by sharing contaminated needles include:
HPV. HPV is most often associated with cervical cancer. But HPV may also increase the risk of cancers of the anus, penis, throat, vulva and vagina. The more sexual partners you have in your lifetime, the more likely you are to have HPV.
Human immunodeficiency virus (HIV). People with HIV or AIDS have an increased risk of anal cancer, cervical cancer, liver cancer, lymphoma and Kaposi's sarcoma. People with multiple sexual partners and intravenous (IV) drug users who share needles have an increased risk of HIV.
Hepatitis B and C. Chronic hepatitis B or hepatitis C infection can increase your risk of liver cancer. Both forms of hepatitis can be passed through sexual contact with an infected person or sharing needles with an infected drug user.
Reduce your risk of these cancers by avoiding risky behaviors. Abstain from sex or use condoms and limit the number of sexual partners you have. Never share needles. Seek help for your addiction if you use drugs.

Cancer prevention step 7: Get screened

Regular screening and self-examination for certain cancers may not prevent cancer, but it can increase your chances of discovering cancer early — when treatment is more likely to be successful. Screening should include your skin, mouth, colon and rectum. If you're a man, it should also include your prostate and testes. If you're a woman, include cervix and breast cancer screening on your list. Be aware of changes in your body — this may help you detect cancer early, increasing your chances of successful treatment. If you notice any changes, see your doctor.

做好的绿豆还是在当天之内吃完较好一些.

据科学测定，有些隔夜菜特别是隔夜的绿叶蔬菜，非但营养价值不高，还会产生致病的亚硝酸盐。储藏蔬菜中亚硝酸盐的生成量随着储藏时间延长和温度升高而增多，而如果将蔬菜放在冰箱中冷藏（2—6摄氏度），则其亚硝酸盐的增加较少。
不同种类的蔬菜在相同储藏条件下，亚硝酸盐的生成量是不一致的。通常茎叶类蔬菜最高，瓜类蔬菜稍低，根茎类和花菜类居中。因此，如果同时购买了不同种类的蔬菜，应该先吃茎叶类的，比如大白菜、菠菜等。如果准备多做一些菜第二天热着吃的话，应尽量少做茎叶类蔬菜，而选择瓜类蔬菜。

炒熟后的菜里有油、盐，隔了一夜，菜里的维生素都氧化了，使得亚硝酸含量大幅度增高，进入胃后变成亚硝酸盐，硝酸盐虽然不是直接致癌的物质，但却是健康的一大隐患。亚硝酸盐进入胃之后，在具备特定条件后会生成一种称为NC（N—亚硝基化合物）的物质，它是诱发胃癌的危险因素之一。

尤其是在天气热的时候，隔夜的饭菜受到细菌污染，会大量繁殖，很容易引发胃肠炎，食物中毒。

炒熟的菜中，很多吃不完存放起来，尤其是一些高蛋白高脂肪的剩菜，更是吃不得。空气中的有害细菌会在2个小时内附着在剩菜上开始繁殖，大家都知道蛋白质和脂肪在细菌的作用下，大部分都会产生有害物质，如硫化氢、胺、酚等，这些物质对人体有害。长期吃剩菜容易致癌，这已经是不争的事实。所以说隔夜菜不能吃，在做菜的时候，最好的办法是量体裁衣，而不能损害健康！

　　本报讯 “比赛之前我都吃得很少，只有饿着我才能有动力，吃得太饱人就会变得慵懒。”昨天下午，伊辛巴耶娃在和李宁的签约仪式上再次抛出她著名的“饥饿论”，虽然她刚刚和赞助商敲定了5年750万美元的巨额合同。在观众看来，伊娃的话或许只能当作玩笑来看，其实真正饥饿的是她那渴望胜利的内心，“我之前说过要在伦敦奥运会后退役，现在我改变了看法，我要跳到2016年。”
　　之前伊娃已经26次打破女子撑竿跳的世界纪录，上一次她破室外世界纪录的表演正是在北京，当时她以5米05的成绩夺得奥运会冠军。“这里是我的福地，能够在奥运会后重新回到北京我感到非常高兴。”一身粉白色系运动装扮，配上标志性的马尾辫，伊娃对自己的未来相当自信。当赞助商公司代表问她能否跳到5米10甚至5米20时，她显然并不满足于这些数字：“高点，再高点。”
　　为了保持良好的竞技状态，伊娃在饮食上十分挑剔。她不吃面包、蛋糕以及一切甜食，只能靠鱼和水果果腹。北京奥运会决赛日，她只是在早上喝了一杯茶，吃了一点点心。“我一直都很饿，”喜欢不断挑战纪录的伊娃说，“饿着才激励我去取得好成绩。”
　　如今的横杆停在5米05的高度上，可撑竿跳女皇的极限到底在哪里？“我认为自己能够跳过5米20的高度，5米30也是有可能的。因为技术上是没有问题的，究竟能跳多高还要看我的身体状况。我收回伦敦奥运会后退役的说法，要坚持到2016年。到那个时候我就很老了，想跳也跳不动了。”本报特约记者 葛晓倩
