保心饮食

保心从日常生活着手

不时有专家提出警告:要预防心脏病还是多注意自己的饮食健康,饮食中少盐少油,少吃富含动物性脂肪的食物,如肥肉、鸡皮等,同时也可用橄榄油取代其他食油。日常食物可多吃富含欧米伽—3脂肪酸的鱼类,同时也应多吃大蒜洋葱及其他各种富含抗氧化剂和抗凝血剂的蔬菜水果,以防止动脉阻塞。 
 
过去有研究显示,地中海区居民的心脏病罹患率比美国人要低得多,地中海边缘国家包括西班牙、意大利、希腊、南斯拉夫、叙利亚等地的饮食具有预防心血管疾病的作用。  
地中海饮食的特点是含大量谷类豆类新鲜蔬果少吃红肉类,以大量药草香料佐料,不添加防腐剂,以及以橄榄油烹调。专家认为,地中海食物大量的谷类、豆类、新鲜蔬果都是膳食纤维的主要来源,而橄榄油含有丰富油脂酸,为一种单元不饱和脂肪酸,研究证实可提高血液中高密度脂蛋白胆固醇(俗称好胆固醇),同时也能降低低密度脂蛋白胆固醇(俗称坏胆固醇)的浓度。  

在一日三餐方面,正确的饮食习惯应该是早餐吃得丰富,摄取较高热量食物。晚餐则应少碰油腻食物,饮食宜清淡,摄取热量不超过全天之30%。专家认为,晚餐吃得过于丰富或油腻,会造成血脂量升高,加上睡眠时人之血液流动较慢,大量血脂易沉积在血管上,会造成动脉硬化、高血压及心脏病。  
对于那些有心律不整毛病,而又有喝咖啡习惯的人来说,最好控制喝咖啡的数量,每天不要超过两杯。  

但研究人员也提醒大众,除了注意饮食仍是不够的,要预防心脏病,正确的做法是,配合有规律的健康生活方式,多运动、保持心情愉快,才可远离心脏病。

十种增强免疫力的食品

  1. 酸奶或奶酪酒:其中的乳酸菌和双歧杆菌可以对抗肠内有害物质的攻击。还可以增加体内白细胞的长生。奶酪酒还能产生酵母菌,补充体内缺乏的氨基酸。
  2. 姜黄粉:中国菜和印度咖喱里必不可少的姜黄粉含有姜黄素,可以阻挡免疫细胞受到刺激物的攻击,也能中和抗生素色副作用。姜黄可以和某些蛋白质发生作用,它杀死癌细胞的数字是杀死健康细胞的10倍。姜黄尤其对前列腺癌和乳腺癌有效。
  3. 大蒜:大蒜里的硫磺类化合物对细菌、病毒、真菌和寄生虫类感染都有灭杀作用。除增强免疫力外,大蒜也有抗癌和抗氧化的功效。大蒜还可以降血脂、稀释血液、降血压。每天吃大蒜的人比不吃的,胃癌患病率低一半,肠癌患病率低80%。蒜最好生吃,捣成泥后放置15分钟,不宜空腹吃。胃溃疡、偏头痛和有牙周病的人,最好不吃蒜。
  4. 牛至:这种有清热、化湿、祛暑、解表、理气作用的草本植物是非常好的天然杀菌剂。牛至里面的石碳酸和类黄酮有消炎和抗氧化作用。食用牛至可以治疗感冒、发烧和消化不良。
  5. 甜椒:具有低卡路里、营养密集的特点。富含胡萝卜素和维生素C。甜椒所含维生素C是橙子的两倍。维生素C已经被证明是加强免疫力、抗击感冒最有效的安全成分。
  6. 绿茶:富含多酚,在烘干和处理过程中被氧化的几率最小。绿茶提取物已被证明可以抑制关节炎、预防老年痴呆、阻止细菌复制、有消炎和抗氧化作用。此外绿茶提取物已经被应用于癌症治疗中。
  7. 南瓜:黄色的瓤不仅富含胡萝卜素,也是维生素A的聚集地。维生素A可以帮助规范人体细胞之间的交流,是免疫系统工作的基础。维生素A也有助于呼吸系统。但过多维生素A会囤积在脂肪里会中毒。
  8. 生姜:肉质肥厚,香味辛辣。生姜的辛辣成分叫姜油酮,有温暖、兴奋、发汗、止呕和解毒作用。生姜干后,姜油酮变少,姜酚素增多,消炎作用加大。夏天的空调病、冬天的风寒,都可以用一碗简单的红糖生姜水解决。此外,生姜和蒜一样对男性都有壮阳作用。
  9. 牡蛎:牡蛎一直被认为是最好的天然春药,原因是富含锌,可以刺激睾丸激素的分泌,对男女性欲的激发都有辅助作用。锌比其他任何矿物质都对酚类敏感,是免疫系统不可缺少的要素。锌可以加强T细胞,预防过敏。
  10. 花椰菜:富含维生素A、C、E,是对免疫系统最好的蔬菜。其中菜花可以提高肝脏的芳経羟化酶的活性,增强抗癌物质的分泌。西蓝花是最好的蔬菜,可以提高肝脏解毒的功效,可以降低血糖,调节血压,具抗癌效果。紫甘蓝也有类似功效。

塑造小蛮腰——如何正确收缩腹部

为了追求超平坦的腹部,许多人都以为每天要做几百次腹部收缩,也就是健身行话“仰卧起坐”。但你可曾想过健身房中使用“腹部运动器”的人,为何看起来还是像“腹中有篮球”呢?
  腹部肌肉几乎是每一个动作的辅助器:由伸手取高架上的东西到挥杆打高尔夫球。它支撑著脊柱,因此能协助我们维持正当的姿势,同时也是支撑腹腔壁的唯一来源。这些功能都 要肌肉的力道,但是做200次腹部收缩运动也仅能改进它的耐力。要使它强壮,就必须锻链肌肉承受力,只 在肩部离地时多承受一个哑铃之类的举重器材就可以了。
  ●下面告诉你如何才能正确的收缩腹部:
  1、平躺在铺有地毯的地板或运动垫上,将手放在两侧伸展双腿。
  2、将膝盖微微弯曲,脚跟贴住地板。如果你感到背部太弯或太紧,可将膝盖再多弯一点,直到感觉舒适为止。不要强迫背部紧贴地板。
  3、将双手放在颈后。如果放得太高,每次收缩时便会压迫头部并且可能扭到颈部。
  4、深呼吸,吐气时收缩腹部肌肉。收缩使肌肉紧缩,便自然的将肩膀拉起离开地板。让你的颈部挺直但不要紧张,身体抬起,与地板的角度不要超过三十度。慢慢将上身躺回地板,同时吐气。重复10-15次。
  如果想让腹部缩得更紧一点,做下面一项运动,或两样都做。
  1、维持腹部紧缩,数到四,然后放低身体并立刻再抬起,支撑住再数四下,重复5-10次。
  2、将一个手臂伸到头部后方(如果你是站著,姿势好像是要触及天空一般)。这样能增加加诸于腹部肌肉的“重量”。换另一个手臂重复做5-10次。
  ●这些你都知道吗——
  为何人们不再伸直腿做仰卧起做了?因为腹部肌肉对躯干的收缩只局限于臀部屈肌(连接骨盆与大腿骨的肌肉)产生作用之前的某一点上。如果有任何肌肉需要强化,那就是臀部屈肌。你走路,跑步,站立,上楼梯时,都用得著它。
  另外收缩腹部时将脚跟抬起离地一到两寸,能迫使在躯干前面交叉的腹部斜肌,采取稳定身体的动作。如果你做到这一点就太棒了!简单的收缩动作立刻便成了腰围缩减器了。

About Strokes - You could save a life

STROKE: Remember The 1st Three Letters... S.T.R.
My friend sent this to me and encouraged me to post it and spread the word.
I agree. If everyone can remember something this simple, we could save some folks. Seriously..
Please read:
STROKE IDENTIFICATION:
During a BBQ, a friend stumbled and took a little fall - she assured everyone that she was fine (they offered to call paramedics) and just tripped over a brick because of her new shoes. They got her cleaned up and got her a new plate of food - while she appeared a bit shaken up, Ingrid went about enjoying herself the rest of the evening. Ingrid's husband called later telling everyone that his wife had been taken to the hospital - (at 6:00pm , Ingrid passed away.) She had suffered a stroke at the BBQ. Had they known how to identify the signs of a stroke, perhaps Ingrid would be with us today. Some don't die. They end up in a helpless, hopeless condition instead. It only takes a minute to read this...
A neurologist says that if he can get to a stroke victim within 3 hours he can totally reverse the effects of a stroke...totally. He said the trick was getting a stroke recognized, diagnosed, and then getting the patient medically cared for within 3 hours, which is tough.

RECOGNIZING A STROKE
Thank God for the sense to remember the "3" steps, STR . Read and Learn!
Sometimes symptoms of a stroke are difficult to identify. Unfortunately, the lack of awareness spells disaster. The stroke victim may suffer severe brain damage when people nearby fail to recognize the symptoms of a stroke.
Now doctors say a bystander can recognize a stroke by asking three simple questions:
S * Ask the individual to SMILE .
T * Ask the person to TALK to SPEAK A SIMPLE SENTENCE (Coherently) (i.e. . . It is sunny out today).
R * Ask him or her to RAISE BOTH ARMS .
NOTE : Another 'sign' of a stroke is this: Ask the person to 'stick' out their tongue. If the tongue is 'crooked', if it goes to one side or the other that is also an indication of a stroke. If he or she has trouble with ANY ONE of these tasks, call 000 immediately!! and describe the symptoms to the dispatcher. A cardiologist says if everyone who gets this e-mail sends it to 10 people; you can bet that at least one life will be saved.

Fears over long-term effects of Botox

It must be hard work for big screen siren Nicole Kidman, looking this good at 40. Well, maybe not hard work - but work nonetheless.
For years, the once fragile and freckly skinned actress has been the subject of cosmetic surgery rumours, particularly her alleged penchant for the wrinkle reducing wonder drug Botox.
Now once again in the spotlight, preening for the public and paparazzi at the premiere of Baz Luhrmann's epic Australia, leading cosmetic surgeon and Botox extraordinaire, Dr Mary Dingley confirms the rumours.
And our Nicole's liking for techniques that go well beyond old fashioned beauty sleep, haven't always had the desired effect.
Labelled frozen-faced, called a bat and described by Sharon Osbourne, the wife of rocker Ozzy Osbourne as, controversially said "Nicole Kidman's forehead looks like a flat screen TV."
"Having Botox means that you are going to probably look better, like a china doll. So if you want to be put on the mantelpiece like a china doll then sure this is the way to go" says Dr Mark Williams.

Botox has blossomed into a $300 million a year industry fuelled by Australian women and men, chasing renewed confidence.
But new research published in the esteemed Discover Magazine attacks the long term effect Botox has, saying when it freezes facial expressions it freezes emotions.
"They're going to probably develop things like depression, social anxiety disorders things that are really going to affect their health in the long term" says Dr Mark Williams.
Humans and many animals rely intrinsically on facial expressions to understand each other and experience emotion.
"When you actually take away the ability to make a facial expression then you are not going to be able to portray that to others so others aren't going to be able to understand if you are sad or if you are happy" says Dr Williams.
Macquarie University cognitive neuroscientist Mark Williams says Botox users don't have the same highs and lows of emotions and can't recognise them in others.
According to the theory...it works like this. When a person smiles at us we smile back - it's automatic. We literally mimic them, even if it's only for a split second.
"There's a lot of evidence that what we do is mimic what the other person is doing and we get the same physiological response that they get, so we are yeah you are happy because I'm feeling happy or you are sad because I'm feeling sad" says Dr Williams.
The act of smiling or frowning or grimacing literally triggers a response in our brains you can see.
The theory was first pushed in 1872 by Charles Darwin who claimed facial expressions were a crucial means of survival allowing us to tell our enemies from our friends - even before we could speak.
In 2008 Dr Williams uses state of the art technology to scan the brain. He shows his subjects pictures of different facial expressions then reads their neurological reaction.
"There are seven basic emotions that we talk about and those are happiness, sadness, surprise, disgust, angry, fearful and neutral faces and they occur in any society from the highlands of Papua New Guinea all the way to Sydney Australia, New Zealand wherever" adds Dr Williams.
He says Botox will reduce emotion across the board.
"They won't be able to smile so therefore they wont get all those endorphins released so therefore they wont get that rush of enjoyment that we all get. Also from the point of view they are not going to get the interaction with others that they are looking for so others aren't going to understand how they are feeling."
Paralyse your expression...paralyse your relationships.
"No-one wants to talk to you because you are not showing the normal signals an individual shows when they are interacting and enjoying it."
"I've had three botox injections around my eye...I've had three in between my nose, I've had three on the other side and two on my chin." Sonya is an avid botox user. She says it has improved her relationships, not dulled them.
"Not at all... I mean botox has helped me. Really, its made me feel more confident. I don't think its hindered me at all, it's been a great thing for me."
Her doctor, also a regular botox patient, agrees.
Dr Mary Dingley from the Australasian College of Cosmetic Surgery says treatment can actually improve a person's wellbeing and help with depression, particularly in people who have deep frown lines.
"Look I think the reverse is true. it actually allows people to interact with people better so they are not going to be isolated," Dr Dingley said.
"So if you're walking around like a thundercloud all the time, people will think that you are very cranky even if you're not. So a lot people with botox can relax that frown and people find you more approachable," says Dr Dingley.
And the smile remains untouched.
"Certainly we are not doing anything with the smile muscles, you can still smile perfectly naturally. And you can still show surprise, you can still show affection, all of those sorts of things," adds Dr Dingley.

会让你变笨的12种食物

1、泡泡糖  
泡泡糖中的天然橡胶虽无毒,但制泡泡糖所用的一级白片胶是加入了具有一定毒性的硫化促进剂、防老剂等添加剂,多吃会对身体不利。   
2、加糖鲜榨橙汁  
加了糖的橙汁比汽水的热量还要高,糖分也比汽水多。推荐吃原水果。   
3、松花蛋  松花蛋含有一定量的铅,常食会引起人体铅中毒。铅中毒时的表现为失眠、贫血、好动、智力减退等。   
4、臭豆腐  臭豆腐在发酵过程中极易被微生物污染,它还含有大量的挥发性盐基氮和硫化氢等。它还是分解蛋白质的腐败物质,对人体有害。
5、味精  
每人每日摄入味精量不应超过6克,摄入过多会使血液中谷氨酸的含量升高,限制了人体利用钙和镁,可引起短期的头痛、心慌、恶心等症状,对人体的生殖系统也有不良影响。  
6、葵花子  
葵花子中含有不饱和脂肪酸,多吃会消耗大量的胆碱,使体内脂肪代谢发生障碍,并使大量脂肪积聚于肝脏,会严重影响肝细胞的功能。   
7、猪肝  
每公斤猪肝含胆固醇达400毫克以上,摄入胆固醇太多会导致动脉粥样硬化,故猪肝一次不宜吃太多。  
8、腌菜  
长期吃腌菜可引起钠、水在体内潴留,从而增加患心脏病的机会。另外,腌菜含有亚硝酸胺这种致癌物质,久吃易诱发癌症。  
9、爆米花  
爆米花中含铅量高达10毫克/500克左右,对人体,特别是对儿童的造血系统、神经和消化系统都有害。  
10、鱼干片  
鱼片咀嚼时间过长后可浪费唾液,咽下的大量唾液可稀释胃液,降低消化能力。   
11、油条  
油条中的白矾是含铝的无机物,如天天吃油条,铝就很难从肾脏体内排出,体内铝过多,从而对大脑及神经细胞产生毒害,甚至引起老年性痴呆。  
12、.咖啡  咖啡中含有较多的咖啡因成分,一旦被摄入体内消化,它很快就会随血液流动,5分钟内抵达人体各个器官,使血管收缩代谢增快,胃酸尿量增多。
