Curried Lentil, Rice and Carrot Burgers

I love the Indian spices in these burgers. The turmeric offers bonus antioxidant health benefits, but even without it, they’re in abundance in this recipe, with all the carrots and ginger.

2 tablespoons peanut or canola oil

1/3 cup finely diced onion

1 cup finely diced carrots

6 ounces mushrooms, sliced or finely chopped

1 tablespoon minced fresh ginger

1/2 teaspoon turmeric

2 teaspoons cumin seeds, lightly toasted and ground

1 teaspoon curry powder

1/2 teaspoon yellow mustard seeds

Pinch of cayenne (or to taste)

Salt and freshly ground pepper to taste

1 cup cooked brown rice

2 1/2 cups cooked brown lentils, drained

1 egg

 

1. Preheat the oven to 375 degrees. Heat 1 tablespoon of the oil over medium heat in a heavy ovenproof skillet and add the onion and carrot. Cook, stirring often, until just about tender, about 3 minutes, and add the mushrooms, ginger, turmeric, cumin, curry powder, mustard seeds and cayenne and a pinch of salt. Cook for another 3 minutes or so, until the vegetables are tender and fragrant and the spices aromatic. Remove from the heat and transfer to a large bowl. Add the rice.

2. Purée the lentils with the egg and add to the vegetable and rice mixture. Stir together, season with salt and pepper, and shape into 6 patties.

3. Heat the ovenproof skillet over medium-high heat. Add the remaining tablespoon of oil to the pan and, working in batches if necessary, cook the patties for 2 minutes on one side, or until nicely browned. Carefully turn the patties over and place in the oven. Bake 10 to 12 minutes, until the patties are lightly browned and don’t fall apart. Remove from the heat and serve, with or without buns, chutney or ketchup and the works.

Yield: 6 burgers.

Advance preparation: These can be put together and shaped up to 3 days before browning. They can also be cooked ahead and reheated in a low oven or in a pan on top of the stove. Keep them well wrapped in the refrigerator.

Study: 911 Dispatchers Experience PTSD Symptoms Too

It’s not just those on the front lines of disaster or war who are at risk for post-traumatic stress disorder (PTSD), a new study finds. Emergency dispatchers who respond to 911 calls also suffer a mental toll, especially when taking distressing calls involving accidental death and suicide. The new study shows that 911 dispatchers’ indirect exposure to traumatic events can result in symptoms of PTSD.

“Usually research considers links between disorders and how much emotional distress is experienced on the scene of a traumatic event,” said study author Dr. Michelle Lilly of Northern Illinois University in a statement. “However, this is the first study on emergency dispatchers, who experience the trauma indirectly.”

For the study, published in the  Journal of Traumatic Stress, researchers questioned 171 emergency dispatchers currently working in 24 U.S. states. The dispatchers — predominately white women around age 38 with more than 11 years of dispatching experience — were asked about the types of calls they answer and their corresponding emotional distress. They participants then rated the types of calls that caused great distress and were asked to recall the worst call they ever received.

About 16% of the calls dispatchers identified as their worst involved the unexpected injury or death of a child. About 13% were suicidal callers, 10% were police-officer shootings and another 10% involved the unexpected death of an adult.

The researchers report that the dispatchers experienced a high level of distress following 32% of potentially traumatic calls and that 3.5% of the dispatchers reported symptoms severe enough to be classified as PTSD.

Not knowing what happens after calls are dispatched is a significant stressor for dispatchers, ABC News reports. “We don’t know the end result. We don’t know if they made it. There is no formal communication back to us,” Monica Gavio, a coordinator for the Burlington County, New Jersey, 911 communications center, told ABC News.

“The results show the need to provide these workers with prevention and intervention support as is currently provided for their front-line colleagues. This includes briefings and training in ways to handle emotional distress,” study researcher and former 911 dispatcher Heather Pierce said in the statement.

In the study, researchers note the potential public safety concerns their findings bring to light:

Post-traumatic stress disorder symptoms that may be present in telecommunicators can impair decision-making abilities and functioning, which could pose significant risk to the general population that relies on them to quickly and effectively coordinate an emergency response.

The researchers also suggest that their findings could contribute to the debate over the definition of a “traumatic event,” as official guidelines are set to be published next year.

Breast Cancer Risk May Be Higher With Just One Drink a Day

 

Consuming as little as one drink a day or less may raise a woman’s risk of developing breast cancer, according to a new study published this week.

European researchers analyzed data from more than 100 studies that looked at the relationship between alcohol consumption and breast cancer and found that having up to one drink per day raised women’s risk for the disease by 4 percent. Three or more drinks per day increased risk by 40 to 50 percent.

“Women should not exceed one drink [per] day, and women at elevated risk for breast cancer should avoid alcohol or consume alcohol occasionally only,” concluded the authors, led by Helmut K. Seitz of the University of Heidelberg in Heidelberg, Germany.

Previous research has also found a link between light alcohol consumption and elevated breast cancer risk. A study published in November found that as few as three to six drinks per week raised risk by 15 percent.

Some experts said the findings support current recommendations for women to drink in moderation in order to minimize their risk of breast cancer as well as other health conditions. They added that while it’s important to avoid excessive drinking, women should also consider alcohol as one of numerous factors that can play a role in the development of cancer and other illnesses.

“The American Cancer Society guidelines say that for women who don’t drink, there is no reason to start drinking, and not just to prevent breast cancer. It can even prevent heart disease,” said Susan Gapstur, vice president of epidemiology research at the American Cancer Society. “For women who do drink, they should limit their consumption to no more than one drink per day. This study underscores that these guidelines are reasonable.”

Dr. Stefan Gluck, a professor at the University of Miami Sylvester Cancer Center, argued that although excessive drinking should absolutely be avoided, there is nothing wrong with having one drink a day. The 4 percent increased risk among women who had one drink a day is a very small increase, he said, and other factors play a bigger role.

“There are many other things that are more important,” he said. “If you look at the American Association for Cancer Research report from last year, 30 percent of all cancer deaths were attributable to smoking and another 30 percent were attributable to obesity.”

That same report found alcohol played a role in about 3 percent of cancer deaths.

Gapstur added that even though the study found light drinking elevated risk only moderately, breast cancer is a very common cancer, meaning 4 percent can add up to a lot of women.

 

Past Studies Contradictory?

Other studies have found that moderate alcohol intake can protect against heart disease.

“A large number of observational studies have consistently demonstrated a reduction in coronary heart disease with moderate alcohol consumption. Prohibiting alcohol consumption would deny a potentially sizable health benefit to people who would otherwise choose to drink,” the American Heart Association says on its website.

The American Heart Association recommends that women have no more than one drink per day.

While she stressed that a drink a day should be the maximum, Gapstur added that women should get an overall picture of their individual risk for different illnesses to get a better sense of what lifestyle changes to make to improve overall health.

“The message continues to be know your health, maintain your health, see your doctor regularly and understand your risk for cancer and heart disease,” she said.

Cancer: ‘Book of knowledge’ published


Cells from a cancer line known as HeLa

The first volume of a “book of cancer knowledge” has been published, which scientists say will speed up the search for new cancer drugs.

The “encyclopaedia” details how hundreds of different cancer cells respond to anti-cancer agents.

UK, US and European researchers say the data, published in Nature, is a step towards tailoring cancer medicine to a patient’s genetic profile.

A cancer charity said the work would help in testing new cancer drugs.

Cancer cells grown in the laboratory are an essential tool in cancer research.

Hundreds of different cell lines exist, allowing scientists to study the effect of new cancer drugs on the human body.

Cancer medicines linked to genetic profiles

  • A new drug called vemurafenib offers hope to malignant melanoma patients with certain genetic markers
  • Erlotinib helps some lung cancer patients by targeting a receptor found in some tumours. Another new drug, crizotinib, tackles lung cancer expressing the ALK gene
  • The breast cancer drug Herceptin is given to patients with an overactive HER2 gene
  • The cancer drug imatinib blocks cancer growth in white blood cells of patients with chronic myeloid leukaemia carrying a certain gene mutation

Now, a team at the Wellcome Trust Sanger Institute near Cambridge and various cancer institutes around the world have released two papers cataloguing data on hundreds of cancer cell lines.

The UK team, working with colleagues in the US, Paris and Switzerland, screened more than 600 cancer cell lines with 130 drugs, identifying genetic signatures linked with drug sensitivity.

Already clues are emerging that could be of benefit to patients, including the discovery that a rare bone cancer in children (Ewing’s sarcoma) appears to be vulnerable to certain drugs.

Personalised medicine

Dr Mathew Garnett of the Sanger Institute is lead researcher on one of the two papers published in the journal Nature.

We’re trying to get smarter about understanding what the right drug is using the genetic profile in each tumour”

Dr Levi Garraway Oncologist

He told the BBC: “It’s bringing together two very large and very powerful data sets and asking which cell line is the most sensitive and what is behind that sensitivity.

“This is the largest study of its kind linking drug response with genetic markers. You need these very large studies to identify small subsets of cells that are sensitive to drugs.”

Dr Levi Garraway of The Broad Institute of Harvard and MIT, Cambridge, US, is a senior member of the research team behind the second paper, which profiled 24 drugs across nearly 500 cell lines.

He told the BBC: “Developing this large cell-line resource with all the associated genetic details is another piece in the pie to get us to our goal of personalised cancer medicine.

“We’re trying to get smarter about understanding what the right drug is using the genetic information in each tumour. This is a stepping stone along the way.”

The next step is use the information to help decide on tailored treatments for cancer patients.

This would involve getting a genetic “fingerprint” of their tumour, which could be matched to information in the database.

Some cancer drugs are already available for individuals with a certain genetic makeup.

The best known is Herceptin, a breast cancer drug that works in patients with an overactive HER2 gene.

Professor Charles Swanton, based at Cancer Research UK’s London Research Institute, said the papers were “an invaluable resource” that provided “extremely useful intelligence” for cancer researchers.

He added: “This new resource will help speed up cancer research and may well begin to guide further developments in personalised cancer medicine.”

New MRSA bacteria test developed by Edinburgh University scientists


Current techniques for detecting MRSA can take a full day

 

New MRSA bacteria test developed by Edinburgh University scientists

It works by taking swabs from a wound or sores, which are then analysed using a strip with electrical sensors that can detect MRSA.

It is hoped the tests will allow almost immediate detection of the bacteria.

This would allow patients to be given more effective drugs straight away.

The swab samples are currently processed in the laboratory to increase the amount of bacteria present before they are tested with the strips.

But the researchers hope to avoid the need for this in the future by improving the strip’s sensitivity in order to allow the tests to be used in GP practices and people’s homes.

Laboratory tests to confirm whether MRSA is present in a wound can take a full day using conventional techniques.

The new test was developed using swabs from diabetic foot ulcers taken from patients attending NHS Lothian’s Diabetic Foot Clinic at the Royal Infirmary of Edinburgh.

Detection of MRSA in these patients is important to prevent the spread of infection, which can lead to the amputation of limbs and increase the risk of mortality.

Dr Till Bachman, from the University of Edinburgh’s Division of Pathway Medicine, will present the research behind the test at the Advances in Biodetection and Biosensors conference in the city on Thursday.

He said: “Current tests for MRSA tend to be expensive and not very fast. By developing a rapid and cost-effective test, we would know what kind of infection is present straight away, which will improve the chance of success in treating it.”

Edinburgh scientists are using similar technology to monitor signals that bacteria send to each other to spread infections, and chemicals that patients produce that indicate the wound’s response to the infecting bacteria.

Understanding why bacteria release certain molecules as part of this process will help scientists identify the start of an infection and so treat it promptly.

手術加復健 掌握黃金治療期 全身癱瘓進步神速 可寫字、走路


▲鄭先生(右)在外勞幫忙固定紙張下,可以寫字。(記者謝鳳秋攝)


記者謝鳳秋/台中報導

62歲的鄭先生摔倒造成頸椎3至5節損傷癱瘓,神經外科醫師陳子勇第一時間注射高單位類固醇降低發炎反應傷害,接著手術加上努力復健,從全癱到可用助行器行走,機率僅10%,是少見進步神速的案例。

鄭先生與太太昨天到慈濟醫院台中分院感謝院長陳子勇一路相助。鄭太太說,先生原有高血壓、糖尿病,4年前與親友聚餐,離席前10分鐘喝下200CC高粱酒,頭暈目眩又吹到冷風,下樓時踏空摔倒,眼鏡破裂,碰撞造成右眉深度撕裂傷,直說手麻,馬上叫救護車送醫。

透過急診電腦斷層檢查,確定頸椎第3到第5節嚴重滑脫,再加上椎間盤突出直接壓迫到脊髓神經,導致脊髓損傷,學護理的鄭太太知道「高位頸椎受傷,會影響呼吸、四肢活動及大小便控制」,馬上連絡陳子勇。

陳 子勇建議急診先注射高單位類固醇,降低發炎反應對神經造成的傷害,當晚轉診至慈濟醫院台中分院,照頸椎核磁共振掃描證實為「外傷性頸椎椎間盤突出合併完全 性脊髓損傷」,手腳不能動、肛門周圍也無知覺,依美國脊髓損傷協會「脊髓損傷嚴重度分級」,傷勢屬於最嚴重的完全損傷。

2天內進行「減壓性頸椎椎間盤切除合併椎體護架植入手術」,避免神經再遭受壓迫,同時進行清創縫合右眉撕裂傷與氣管切開手術。

鄭先生轉入普通病房,開始復健治療及呼吸器訓練近2個月後出院,展開復健治療,1年後,他已從原本的完全損傷(下肢肌力0分)進步到不完全損傷(下肢肌力3到4分),可以在使用助行器情況下,站起來做短距離行走。

陳 子勇指出,全身癱瘓要恢復行走功能極不容易。根據文獻報告,脊髓完全損傷的人要恢復到扶助行器走路,機率僅10%,重點在掌握治療黃金期,一受傷應先固定 好頸椎,再搬運送醫,受傷初期注射類固醇,避免神經發炎,並在48小時內進行減壓、固定手術,接下來就要靠家人陪伴,鼓勵他努力不中斷復健。

從私人企業成功的經理人到全身動不了,鄭先生一度生存意志薄弱,埋怨太太:「當初怎麼不放棄我?」、「那些復健都是妳要的,不是我想做的」。

鄭太太說,那時很堅定地告訴先生:「把我的手腳當你的手腳,傾家蕩產也要把完整的你救回來。」她提早從公家機關退休,全心陪伴復健,但也因想盡辦法要讓先生快點好起來,一度累到不能吃、不能喝,身心症狀上身,驚覺她不能倒下去而調整腳步。

鄭先生持續到醫院復健,在家時每天上、下午也各花一個半小時做復健,已可以寫字、自己用手拿餅乾吃。他說:「讓別人餵飯,會覺得人生沒有希望,能自己拿著餅乾吃,感覺特別香。」

他接下來的心願,是能拿枴杖走路、恢復自理的生活,他也鼓勵其他病患,千萬不要自我放棄。

過敏時上妝完全OK,零敏感掀熱潮!

中國時報【台北訊】

 

天氣漸漸回溫,又到了春暖花開令人愉悅的時節,但在季節轉換及日夜溫差大的情況下,皮膚過敏也讓皮膚科門診開始出現了排隊人潮。根據統計,台灣約每三人就有一人為過敏所苦。

 

迅速抗敏止癢,皮膚科醫師首選類固醇幫助解決肌膚不適,但醫師也表示,類固醇雖具有立即消炎、抗敏的作用,無法當作日常抗敏保養。長期使用,類固醇 累積不易排出,還可能會引發皮膚的萎縮、紫斑和擴張紋,對肌膚或是人體都是一大傷害。網路上近來也出現了除了藥物之外,如何有效迅速對抗過敏的討論風潮。 多數敏感肌網友表示,最討厭一換季過敏就來報到,好想擺脫一直擦藥的宿命!最怕藥物擦多了變成月亮臉!也有網友感慨,為了遮蓋敏感泛紅,還是用了遮瑕膏, 或是工作必須需要化妝,但醫生囑咐過敏不能化妝,好兩難!

 

市面上少有即時修護敏感肌膚的抗敏產品。日前業者推出使用高效天然成分能迅速阻斷肌膚過敏訊號的修護產品,針對肌膚搔癢泛紅可即刻處理,讓消費者擺 脫過敏泛紅無法上妝的窘境。此產品自推出起便引起網友與部落客的熱烈討論。網友天天說:真的很怕類固醇用多反而更糟,抱著試試看的心情試用了瞬間無敏修護 水凝霜,真的很快就不癢,頑固的換季過敏短短三天就馬上縮小泛紅範圍!

 

另一長期有脂漏性皮膚炎困擾的網友小馬也表示,除了夜間使用穩定肌膚狀況外,因為平時就有上妝的需求,乾脆把瞬間無敏修護水凝霜加入底妝或隔離霜混合使用,沒想到敏感肌膚不像從前一上妝就鬧脾氣,反而非常穩定,妝容也很服貼!

 

業者說,此水凝霜具迅速舒緩的功效,去年在香港上市即造成熱賣缺貨,導致台灣未能同步販售。香港熱賣期間旋即有消費者替產品取了暱稱 ─「零敏感」。因內含豐富的燕麥仁油萃取的氨基酸,可迅速提高肌膚保水度,立即舒緩皮膚因過敏所引起之泛紅刺痛等現象。業者表示,不少消費者的心聲是除了 能迅速舒緩搔癢紅腫之外,更希望能恢復肌膚自主的抗敏功能,擺脫過敏反覆發作的循環。因此在研發時加入天然草本萃取的循環調理複方,提升皮膚對環境傷害的 保護力,長期使用下來能增強肌膚自主的抗敏功能。

 

網友ling說,雷射後最怕用到非低敏性產品,也怕化妝之後突然冒出的紅腫。因此隨身攜帶零敏感,有點癢就擦一下,可以讓膚況維持良好狀態。業者得 知網友們充滿創意的使用方式,表示:還是會建議敏感的狀態下,避免化妝刺激皮膚,但看見大家使用過後膚質都轉為穩定,十分開心。業者認為,肌膚在健康狀態 下就像晶玉瓷般,是強壯又美麗的。零敏感也可用在身體過敏部位,但常接到消費者反應捨不得用在身體,特地推出換季抗敏優惠,讓更多深受過敏困擾的消費者都 能擁有「晶瓷肌」。

吃够维生素 让衰老有多远走多远

时间是把杀猪刀。日常生活中的阳光曝晒,电脑辐射,汽车尾气、炒菜油烟,使用化妆品,甚至呼吸,都在产生一种很不稳定却无处不在的物质,使得皮肤失去弹性,越来越粗糙并产生皱纹;身体机能下降,抵抗力越来越差;各种疾病也随之而来……而造成我们逐渐衰老的物质就是自由基。

维生素家族维生素家族

自由基怎样让我们变老

衰老的过程其实就是一系列的氧化反应。人的生存离不开氧气,但是在身体耗氧的过程中,大量自由基被释放。细胞膜受到自由基氧化反应的攻击,就会 失去弹性并使得细胞丧失功能,更可怕的是,因此导致基因突变从而引起机体系统性的混乱。大量资料已经证明,炎症、肿瘤、衰老、血液病以及心、肝、肺、皮肤 等各方面疾病的发生与体内自由基产生过多,人体清除自由基能力下降有着密切的关系。

维生素有多重要

维生素是人体生长和代谢所必需的微量有机物,在维持人体的生理功能方面有重要作用,同时帮助身体形成有效的抗氧化机制,不但可以直接消灭自由 基,而且还可以通过参与形成消灭自由基的抗氧化酶,间接保护细胞。已发现的维生素有20多种,分为水溶性维生素和脂溶性维生素两大类。前者包括B族维生素 和维生素C。后者包括维生素A、维生素D、维生素E、维生素K等。

维生素A  最“视觉系”维生素

维生素A又名视黄醇,从名字上能知道和视觉系统有直接的关联。其实早在唐朝,名医孙思邈在《千金要方》中已经明确记载动物肝脏可治疗夜盲症。而 维生素A确实大量存在于动物肝脏中。是一类在结构上与胡萝卜素相关的脂溶性维生素。不但帮助人体维持正常视觉功能,还能维持骨骼正常生长发育,同时对于上 皮的正常形成、发育与维持十分重要。

维生素A的前体β-胡萝卜素具有抗氧化作用,是机体捕获活性氧的有效抗氧化剂,对于防止脂质过氧化,预防心血管疾病、肿瘤,以及延缓衰老均有重要意义。同时对于机体免疫功能有重要影响,能有延缓或阻止癌前病变特别是上皮组织肿瘤。临床上作为辅助治疗剂已取得较好效果。

B 族维生素 最“多样”维生素

已知B族维生素有12种:维生素B1、维生素B2、维生素B6、维生素B12、烟酸、泛酸、叶酸等。在维持人体运转中发挥着各自不同的生理功 能,如维生素B1和B2能降低人体罹患肠道癌和卵巢癌风险;叶酸对于胎儿脑部发育有着重要作用;缺乏维生素B1容易引起脚气病及肠胃功能紊乱;缺乏维生素 B6容易引起贫血和溢脂性皮炎;B族维生素之间有协同作用,一次摄取大部分或者全部要比分别摄取效果更好。

B族维生素是非常好的抗氧化剂,可帮助清除肝脏脂肪,降低胆固醇,预防动脉硬化。维生素B还能预防太阳晒伤及皮肤癌,保持皮肤光滑滋润,延迟皱纹的出现,另外还能促进毛发健康生长。

维生素C 最“解毒”维生素

维生素C是一种水溶性维生素,有着广泛的解毒作用,能在很大程度上缓解铅、汞、镉、砷等重金属对机体的毒害。据调查,在污染环境工作的人保持体 内高水平维生素C以后,对有害元素的吸收则大幅度降低。维生素C可清除体内由抽烟引起的尼古丁,更重要的是,维生素C可以阻断强致癌物亚硝胺的合成。每天 吃富含维生素C的新鲜水果,会大大降低各类癌症的发病率。

维生素C是重要的抗氧化剂,不但自身可以清除自由基,还能和维生素E在体内协同作用,使得清除自由基的功效加倍。同时可以保护如维生素A、维生素E、不饱和 脂肪酸等其他抗氧化物。维生素C能够治疗坏血病并具有酸性,所以又称作抗坏血酸。

维生素D 最“强壮”维生素

维生素D是一种脂溶性维生素,民间一直流传“多晒太阳可补钙”的说法,事实上,受阳光中紫外线的照射后,人体内的 胆固醇能转化为维生素D。而维生素D的生理功能是帮助人体吸收磷和钙,是骨骼生长的必需原料。

有助于形成骨骼和软骨,具有抗佝偻病作用。另外,维生素D还能使牙齿坚硬,此外对炎症有一定的抑制作用。

维生素E  最“性感”维生素

维生素E又名生育酚,对人体生长发育有重要作用,能促进人体性激素分泌,使女性 雌性激素浓度增高,提高生育能力,同时还能改善月经不调及性冷淡;可使男子 精子活力和数量增加,防治男性不育症。另外,维生素E在美容方面有着特别的功效:能保护皮肤免受紫外线和污染的伤害,减少疤痕与色素的沉积,同时还能加速 伤口的愈合。

维生素E是一类非常重要的强抗氧化剂,不但自身可清除自由基,还可保护 不饱和脂肪酸,维生素A和ATP等其他抗氧化物;保护机体细胞免受自由基的毒害。维生素E还有改善脂肪代谢和血液循环,降低胆固醇及甘油三脂,预防高血压 的作用。另外,还能降低细胞的需氧量,从客观上减少了氧化反应的发生。

维生素K  最“不缺”维生素

维生素K属脂溶性维生素。具有促进凝血的功能,故又称凝血维生素。1929年丹麦化学家达姆从动物肝脏和麻子油中发现,具有防止新生婴儿出血疾 病、预防内出血及痔疮、减少生理期大量出血、促进血液正常凝固的作用。缺少它凝血时间会延长,严重的话会流血不止,甚至死亡。有意思的是人的肠道中有一种 细菌会源源不断地制造维生素K,因此通常人体不会缺乏。

日常生活中抗氧化

运动注意适量

运动时会发生比平常多的自由基, 一旦运动过量,体内自由基中和系统来不及修补,就会在体内积累对身体造成损伤,因此运动要适量。运动过后可以食用富含维生素C、E、β-胡萝卜素的各种青菜水果,来中和体内的自由基。

避免过量服药

众所周知,许多药物都有毒副作用。例如抗生素,消炎痛剂,化疗药物都会产生自由基,长期服药会造成身体内自由基大量累积。

喝水要喝好水

弱碱性水中含有大量的电子,呈负电位,这些多余的电子可中和并清除自由基。纯净的弱碱性饮用水,是身体最好的水分补充物。

坚决远离香烟

抽烟会迅速产生大量自由基,据调查,每吸一口烟会制造十万个以上的自由基。抽烟可引发各类癌症,并加速癌细胞生长。同时会造成例如心血管病症、糖尿病及肺部疾病。请记住:二手烟伤害比一手烟更大。

减少做菜油烟

日常做饭免不了煎炒煮炸,由于大多数家庭习惯使用色拉油,在高温下会产生大量自由基,从呼吸道进入人体。因此做菜尽量避免煎炸,改用蒸煮为好。

拒绝加工食物

食品加工过程中不可避免地会使用色素、防腐剂及香料,过量食用身体会产生大量自由基。例如腌制食品含有 硝酸盐,会在胃里和蛋白质合成强致癌物硝酸胺。而维生素C可以有效阻断硝酸胺的形成。

少吃烟熏烧烤

高脂肪及蛋白食物在烟熏、烧烤过程中,肉类油脂滴入炭中,在高温下分解形成毒性强的致癌物苯并芘,随烟熏挥发回到食物中。

小心农药污染

农药的使用会产生大量自由基。若有条件的话,要选择有机农产品,或者将果蔬放入冰箱一至两天再食用,可降低百分之八十至九十之农药残留量。

食用蔬菜水果

新鲜蔬果中含有大量天然抗自由基的维生素及黄酮素以及纤维素。每天至少食用三种颜色以上生鲜蔬果对身体很有好处。

维生素存在于哪些食物中

B族维生素 :谷物、果蔬、牛乳、蛋黄、鱼类、禽类、瘦肉、动物肝脏、酵母、坚果、糠麸、大豆等。

维生素C:樱桃、柠檬、橘子、苹果酸枣、草莓、辣椒、土豆、菠菜、花菜、青辣椒、橙子、葡萄汁、西红柿等各类果蔬。

维生素E:果蔬、坚果、压榨植物油、瘦肉、乳类、蛋类,此外在红花、大豆、棉籽、小麦胚芽、鱼肝油中大量存在。

维生素D:鱼肝油、动物肝脏、蛋黄、黄油、各种奶制品、三文鱼、金枪鱼等海鱼。

维生素A:动物肝脏、蛋类、乳制品、菠菜、苜蓿、豌豆苗、甜薯、胡萝卜、青椒、南瓜、香蕉、橘子和一些绿叶蔬菜。

最近,發表在《新英格蘭醫學雜誌》在線版上的兩項研究表明:大部分II型糖尿病患者經過減肥手術之後,血糖水平立即降下來。並且在所有糖尿病藥物停止服用後的兩年研究期間,血糖仍能保持平穩狀態。

在美國,超過三分之一的成年人肥胖,超過8%有糖尿病進而引發心髒疾病和中風。約5到10萬人有糖尿病和體重問題。

傳統上醫生們用藥物和胰島素治療糖尿病,雖然也鼓勵減肥和鍛煉,但收效甚微。 而且用於治療糖尿病的藥物許多可能會導致體重增加,雖然通過手術也很少有肥胖患者能減掉足夠的體重。

而現在根據兩項新的研究結果顯示,通過減肥手術控制中等肥胖患者的II型糖尿病病情,比傳統藥物治療更為有效。

兩項研究效果顯著

這兩項研究人員都是比較了服用傳統糖尿病藥物的患者,和經過胃轉流手術使胃體積減少75%的患者以及進行更大膽的膽胰分流術而移除80%胃的患者的血糖水平。後兩項手術使得食物不經過某段消化道來減少腸道內食物吸收。

其中一項研究論文是本周一(3月26日)克利夫蘭診所呈遞美國芝加哥大學心髒病學會議的。他們研究了150名II型糖尿病不受控制的肥胖患者,結果 發現一年後42%的胃轉流手術患者,和37%胃切除手術患者血糖水平恢複正常,而只有12%的藥物治療患者血糖恢複正常。盡管三組的血糖都得到了控制,但 是手術的改善更為明顯,包括體重下降和抗胰島素分泌。 克利夫蘭診所研究人員還指出雖然有4名患者要求重新手術,但也沒有出現危及生命的並發癥或死亡。

第二項研究是由羅馬Cattolica del Sacro Cuore大學和曼哈頓的紐約長老教醫院的研究人員進行的,他們發現的結果更佳,60名晚期糖尿病肥胖患者經過胃轉流手術和膽胰分流術兩年後,分別約有75%和95%病情得以緩和。

顯然,這種減肥手術比處方藥能使更多患者血糖處於正常水平,因此有可能被廣泛用於糖尿病治療。研究人員建議應該向更多該疾病患者推廣這種減肥手術。

很可能對未來治療糖尿病產生重大影響

研究人員還指出,由於大多數患者接受手術後不僅降低了膽固醇,而且改善了血糖和血脂,因此手術還能降低心血管疾病的風險。

該研究的資深合作者暨紐約長老會和紐約市威爾康乃爾醫學院弗朗切斯科魯.比諾博士說,雖然減肥手術最初作為減肥治療目的,最新研究結果表明,減肥手術是治療糖尿病和代謝性疾病“非常好的方法”。

意大利羅馬天主教大學肥胖和代謝性疾病部門主任暨醫學教授Geltrude Mingrone博士說,“這些研究結果證實,減肥手術對可能更有利於對 II型糖尿病的影響,而不是減肥。通過手術改善糖尿病病情的研究將有助於更好地了解這種疾病。”

有的專家更樂觀,認為這一發現可能徹底改變未來的糖尿病治療方法。 他們認為該研究“很可能對未來治療糖尿病產生重大影響”。兩位來自澳大利亞的專家Paul Zimmet和喬治·阿爾貝蒂,在醫學雜誌的一篇社論中寫道,手術“不應被視為作為最後的手段”,應向早期治療肥胖與糖尿病患者提供。”

手術昂貴且有風險

克利夫蘭診所的首席研究員菲利普·紹爾博士在一份聲明中說,“大約一個世紀,我們使用藥片和註射治療糖尿病。而最新研究表明手術治療糖尿病至少對某些病人比複方藥更為有效。”紹爾同時還指出,減肥手術有風險,最常見的副作用是短期的脫水和出血。

手術一般費用約為15,000至25,000美元。雖然醫療保險將覆蓋過度肥胖的糖尿病患者,但高昂的費用還是會阻礙患者的治療,美國只有2%的患者使用減肥或代謝手術,而世界上的比例將更低。

其他專家說,盡管研究結果對於非常胖的糖尿病患者具有鼓舞性,糖尿病通過這種不那麼嚴歷的方式就得以控制,但是減肥手術持久性的療效還尚未確定。
