没有人不认识花生的吧,也没有从来没有吃过花生的吧。

但是这些一种食物并不是所有的人都适合吃它,某一类人群吃花生可能会给生命带来危害性的,所以,有这么一些人群是需要注意了,他们不适合吃花生的。那么,哪些人群不可以吃花生呢?

1、痛风患者:痛风是一组嘌呤代谢紊乱所致的疾病,患者均有高尿酸血症。由于高脂饮食会减少尿酸排出,加重病情,所以痛风急性发作期应禁食花生,痛风缓解期也只能适量进食。

2、胆囊切除者:胆汁对于脂肪的消化和吸收有重要意义。人吃饭,胆囊收缩,将胆汁排入十二指肠以利消化吸收。高蛋白和高脂肪的食物对胆囊刺激最强,使胆汁大量排放。胆囊切除后,胆汁无法储存,势必影响对花生等油料作物中脂肪的消化。

3、胃溃疡、慢性胃炎、慢性肠炎患者:此类患者多有慢性腹痛、腹泻或消化不良等症状,饮食上宜少量多餐、清淡少油。花生属坚果类,蛋白质和脂肪的含量过高,很难消化吸收,此类患者应禁食。

6、高脂蛋白血症患者:饮食结构不合理是导致高脂蛋白血症的重要原因,因此饮食治疗的原则是限制热量、减少饱和脂肪酸和胆固醇的摄入。花生是高脂肪、高热量的食物,多吃只能加重病情,导致冠心病等心脑血管疾病的发生,危及生命。

7、跌打淤肿者:花生含有一种促凝血因子。跌打损伤、血脉淤滞者食用花生,可能会使血淤不散,加重肿痛症状。

通过以上内容的介绍,大家知道花生香脆可口、营养丰富、价格便宜,是男女老幼都喜欢的零食,但如果你属于以上六种的人,花生则对你有害无益。所以,你一定要注意了,为了健康着想一定要注意了不可乱食用花生了。

花生挑选:吃深色小粒的好颜色深的品种,通常富含抗氧化的多酚类物质,其蛋白质和微量元素的含量也会比浅色品种高一些。比如黑芝麻的营养成分胜过白芝麻,黑米胜过白米。所以,相对浅色皮的花生来说,深色皮的花生蛋白质含量要高一些,脂肪含量低一些。而且对于花生仁来说,小粒的花生含的蛋白质高于大粒的。因此,我们不妨改掉喜白爱大的固有爱好,更加眷顾那些深色、小粒的品种。

警惕吃花生的两大注意1、煮食利于过滤致癌物现在是花生大量上市的时间,花生有很多吃法,一般的吃法有“生食,油炸,炒,煮”。 从营养方面考虑,油炸首先不可取; 生食也不可取,因为在花生生长过程中会感染黄曲霉毒素,黄曲霉毒素是公认的最强的致癌物,会沉积在肝脏中,诱发肝癌。 因为黄曲霉菌毒素有水溶性,如果煮吃,基本能把黄曲霉菌毒素滤掉,这样吃煮熟的花生较为安全,也易于消化,营养素的损失最小,炒的话无法破坏黄曲霉菌毒素,所以说煮是最好。

2、“花生的红衣”要慎吃吃的时候还有一个问题,就是关于“花生的红衣”。一般都认为“花生的红衣”中的成分对人体是很有好处的,不错,对绝大部分人是没问题的,具体资料“红皮含有丰富的甘油酯和甾醇酯,具有抑制纤维蛋白的溶解,促进骨髓制造血小板而缩短出血时间,并且有提高血小板的质量,加强毛细血管的吸收性,调节凝血因子缺陷等功能。”也就是说,“花生的红衣”有补血、促进凝血的作用,这对于贫血的人和伤口愈合很有好处。

反过来,另一方面,对于血液黏稠度高的人来说,就没什么好处了,反而会增加心脑血管疾病的风险。 因此,血液黏稠度高的人不宜食用“花生的红衣”,在吃煮花生时最好把皮剥掉;贫血患者如果血液黏稠度高的话,最好采取别的补血措施,比如吃血豆腐等;老年人最好也别吃“花生的红衣”,避免血液黏稠。 另:血液黏稠度可以通过献血或体检查出,或到医院检测。

10醫學美容療程 半無實證易奪命

■崔俊明建議政府先知會公眾醫學美容療程的實際成效和風險,避免市民仍然參加這些高風險的醫學美容療程。香港文匯報記者王維寶 攝

 

香港文匯報訊(記者 王維寶)DR美容事故造成1死3傷轟動全港,令各界關注醫學美容的安全性及療效。香港醫院藥劑師學會調查市面上10種常用醫學美容療程,發現有5種沒有足夠臨床實證支持,安全成疑,更有可能導致紅腫、脫皮及肝功能受損等副作用,最嚴重更可能致命,而另外5種療程,雖被美國食品及藥物管理局納入醫學美容範疇,但必須由受過有關訓練的醫生主理,安全亦無保障。

香港醫院藥劑師學會昨日舉行記者會。香港醫院藥劑師學會會長崔俊明在會上表示,目前坊間流行的5種醫學美容療程包括3種美白針、高濃度血小板血清及磷脂醯膽鹼,全部均需進行皮內注射及靜脈輸注等高風險操作,並缺乏醫學及安全實證,沒有臨床證據證明有美白功效,更可能出現嚴重副作用(表一)。

血小板注射可引致感染

早前DR美容事故,死者就是接受了高濃度血小板血清皮層深處注射。崔俊明指出,血小板注射只用於醫療用途,並無用於美容,療程中如抽血及提取相關成分過程不當,可引致血液凝固問題,「若處理過程中並非完全無菌,可引致感染,最嚴重可致命」。

5療程須受訓醫生主理

另外5項療程雖已納入美國食品及藥物管理局的醫學美容範疇,但都須由受過有關專業訓練的醫生主理,故即使美容中心表示療程由醫生進行,但也不能保證療程沒有風險。學會指出,該些療程的功效常被美容中心嚴重誇大,容易誤導市民,崔俊明建議政府應加強監管美容中心的廣告宣傳,避免誇大失實(表二)。

倡政府設資格審查制度

學會調查亦發現,在15間美容中心的網站中,仍有6間有提供沒有臨床實證支持的療程。崔俊明表示,理解政府成立的督導委員會進行多方面調查需時,但認為應先知會公眾該些醫學美容療程的實際成效及風險,避免有市民仍然參加該些高風險的醫學美容療程。

他又表示,現時市民要向美容中心查詢主理醫生有否專業資格有困難,建議督導委員會除了要研究區分醫學美容和非醫學美容外,並需要規定所有高風險醫學美容要由合專業資格及受過有關訓練的醫生主理,長遠亦設立資格審查制度。

Dengue vaccine to be tested in India: reports

NEW DELHI: French health care giant Sanofi Pasteur will soon test a vaccine against dengue fever in India amid concerns about the increasingly global spread of the disease, reports said Monday.

The vaccine will be tried on about 120 adults followed by trials on children before it can be made available internationally as soon as 2015, the Times of India newspaper said.

“Sites for the vaccine’s final trials will stretch from Thailand to India as this vaccine has to work on populations across countries. We will test it in India soon,” Sanofi’s CEO Christopher Viehbacher was quoted as saying.

Dengue causes a flu-like illness for most victims but one of its strains can cause life-threatening internal bleeding.

There is no licensed vaccine to protect against dengue. Efforts to develop one have been complicated by the fact that there are four different strains, all of which may circulate in an outbreak zone.

Dengue also seems to be exclusive to humans, which means it is impossible to test vaccines on lab animals first.

Jean Lang, head of the vaccine’s research and development programme, said Sanofi had been asked to conduct “phase two safety trials” in India by the national drug controller.

“It will help us get a licence to market the vaccine in India faster if it has been tested on the Indian population and is found safe and effective,” Lang told the paper.

According to the UN’s World Health Organisation, between 50 and 100 million dengue infections occur each year in more than 100 countries. In 1970, the disease was endemic in just nine countries.

India, with a teeming population of 1.2 billion, has become a major focal point for the mosquito-borne viral infection.

Between 2007 and this month, the country has had 32,263 dengue cases with 188 deaths, according to the National Vector Borne Disease Control Programme. Experts say the real numbers are much higher.

New SARS virus linked to bats

Scientists in the Netherlands said they had sequenced the genetic code of a viral sample taken from a 60-year-old man whose death in Jeddah, Saudi Arabia, in June triggered fears that Severe Acute Respiratory Syndrome (SARS) was returning in a new guise.PARIS : A novel strain of the deadly SARS virus that sparked a health scare this year is closely related to a virus found in Asian bats, according to a study published on Tuesday.

The new strain, called HCoV-EMC/2012, is part of a viral family called coronavirus, but in a specific category called betacoronavirus.

Its closest known cousins are a strain found in lesser bamboo bats (Tylonycteris pachypus) and another found in Japanese house bats, Pipistrellus abramus.

“The virus is most closely related to viruses in bats in Asia, and there are no human viruses closely related to it,” said Ron Fouchier of the prestigious Erasmus Medical Centre in Rotterdam.

“Therefore we speculate that it comes from an animal source,” he said, noting that Pipistrellus bats are present in Saudi Arabia and neighbouring
countries.

An epidemic of SARS erupted in China in 2002, eventually claiming around 800 deaths in some 30 countries.

Bats were linked with a novel strain of SARS found in 2005. Hong Kong researchers found a natural “reservoir” of it in Chinese horseshoe bats.

Two other men have also fallen sick in the latest SARS episode.

One is a Qatari man who had been in Saudi Arabia and is being treated at a hospital in London.

There is 99.6-99.7 per cent similarity between his strain and the virus sequenced in the Netherlands, said Fouchier in a press release.

“They are the same species,” he said, adding that the difference was sufficient to suggest that the men had been infected by different sources.

The other is a Saudi man whose case was announced earlier this month by the Saudi health ministry, which on November 4 described him as cured.

The genomic sequence of that virus is not yet available, Fouchier said.

The World Health Organization said that what set the new virus apart from SARS was that it causes rapid kidney failure.

Fears rose last month over the potential spread of the virus during the Muslim hajj pilgrimage in Saudi Arabia. But the kingdom’s health ministry
repeatedly reassured pilgrims that no epidemic outbreaks had been registered.

The new paper appears in mBio, an online journal of the American Society for Microbiology.

Hospitals rely on tags, staff, parents to prevent mix-up of babies

SINGAPORE: Hospitals in Singapore have in place robust procedures to ensure that parents do not go home with the wrong baby.

But they also rely on staff and parents to prevent mistakes.

Channel NewsAsia checked with five hospitals on their systems, a day after KK Women’s and Children’s Hospital (KKH) revealed its mix-up over two babies who were discharged to the wrong sets of parents on Sunday.

All babies are tagged and are carefully checked to ensure that they are matched with their mothers.

Still, the unexpected had happened at KKH.

The baby who left the hospital first had two correct tags with his mother’s name.

The second baby was wearing mismatched tags.

One tag had the name of his mother, while the other carried the name of the mother of the first baby.

It is suspected that his original tag had fell off in while he was in the nursery with the other baby, it was replaced with a wrong tag.

This incident has left many wondering why the checks were not thorough enough.

Other maternity hospitals that Channel NewsAsia checked with also rely on tagging.

Each baby is given two tags minutes after birth and when it is time to leave the hospital, staff would check both tags to confirm their identities.

Mount Elizabeth Hospital takes extra simple steps, such as getting the mothers to read out the babies’ tags.

It also uses Radio-frequency identification to match baby and mother.

Mount Elizabeth Hospital’s chief executive officer, Dr Kelvin Loh, said: “Only if the baby goes off the correct mother, the tag will give off a pleasant chime.

“If the baby goes to the wrong mother, it will actually sound off an alarm so that will be an additional mechanism that will help to match the baby to the right mother.”

At least one other hospital is looking at using new technology to ensure that newborn babies are paired with the right mothers.

KKH is still investigating the mix-up and is working with the health ministry to ensure this will be the only and last mix-up incident.

Diabetics, watch your eyes

.
An eye check is vital. Diabetes patients experiencing vision problem should immediately contact their ophthalmologist.


Without proper management, diabetes can lead to diabetic retinopathy, a leading cause of blindness among adults, writes Dr Asokumaran Thanaraj

A TWENTY-EIGHT-YEAR-OLD woman walks into my clinic, complaining of poor vision in both eyes which she claims happened over the past few weeks. After a thorough eye examination, she was diagnosed with having advanced diabetic eye disease with a loss of vision in both eyes, almost 90 per cent.

She works as a cook at the hawker stall owned by her fiance. She has to be accompanied by him every time she comes to the clinic as she has lost her navigating vision. In medical terms, she is legally blind.

After a long explanation regarding the prognosis and risks involved, she undergoes vitrectomy surgery and endolaser in one eye to repair the damage done by the disease. Post-operation, she gains slight vision which will enable her to navigate, with the other eye remaining at high risk even for surgery.

During follow-up she has one question which I can never answer: “Doctor, when can I see again?”

WHERE DID WE GO WRONG?

Diabetic retinopathy is the leading cause of blindness and visual disability in adults.

The World Health Organisation has estimated the global prevalence of diabetes to rise from 2.8 to 4.4 per cent from the year 2000 to 2030. It is a costly disease both for the affected individuals and health sector. Diabetic retinopathy leads the complication list of diabetes with a worldwide prevalence estimated at 6.8 to 44.4 per cent.

In Malaysia, the prevalence of diabetes among those aged 30 years and above has increased from 6.3 per cent (1986) to 14.9 per cent (2006).

It is recommended that all patients with Type I diabetes be screened for diabetic retinopathy from three to five years after initial diagnosis and for Type II diabetes, the recommendation for screening is immediately at the time of diagnosis.

We can go on giving these figures for public consumption. One can surf the net and find hundreds of pages of information available on this blinding disease.

But what difference does it make for the young woman who has already lost her vision? Is everyone still unaware of these facts and figures?

There are enough seminars, screenings and talks organised by the relevant authorities to tackle this problem.

The Health Ministry has even supplied Fundus cameras to selected primary care centres in this country to help screen patients and to be referred to tertiary centres for review and appropriate treatment.

THE SYMPTOMS

The fact that this patient has been totally unaware of her problem tells us how silent this blinding disease can be. Most of the time, the damage done is so severe that a person can enter the eye clinic for the first time being legally blind without any prior knowledge about his deteriorating condition.

So how does one know if the eyes are affected with diabetic retinopathy?

The answer lies in only getting their eyes screened either by a trained primary care physician, family physician or by an ophthalmologist. Other clues are blurred vision or slow vision loss over time, floaters, shadows or missing areas of vision and trouble seeing at night.

Often, many patients with early diabetic retinopathy have no symptoms before major bleeding occurs in the eye and that is why a regular check-up is needed once they are confirmed having diabetes or still at early stages of diabetic retinopathy.

THE SIGNS AND TREATMENT

The ophthalmologist can diagnose diabetic retinopathy by dilating your eyes and carefully examining the retina. He is usually fully equipped with other assessment tools to help him come to a conclusion about the stages of diabetic retinopathy the patient is suffering from.

In early stages of diabetic retinopathy (non proliferative), no treatment may be needed but the patient will need regular assessment. In cases where the non-proliferative stage has progressed, laser treatment is usually required.
If the condition has progressed to proliferative or advanced diabetic retinopathy stage, surgical treatment is usually initiated. A surgical procedure called vitrectomy is done to clear the blood within the eye which has bled from the abnormal vessels and also to repair a detached retina.

In certain cases, injection of drugs directly into the eye is done. This is to prevent development of any new vessels which are responsible for the bleeding.

FURTHER COMPLICATIONS

At a time when the patient feels everything is solved, the doctors will have to keep their fingers crossed.

This is because diabetic eye disease does not only affects the retina, but it causes other complications like cataract and glaucoma.

Cataract probably is easily manageable but glaucoma or specifically known as neovascular glaucoma is one of the most dreaded complications of the disease.

A few months after the surgery, the patient came for follow up and I was happy to see her being able to navigate on her own without much help. She will need to undergo another surgery to remove the silicone oil placed inside the operated eye to stabilise the detached retina.

I was invited to go to their stall to taste their new cooking and probably a new recipe. It was amazing to see her standing and being able to cook while her fiance was busy serving the dish to the customers.

She is learning to use her sense of smell, touch and taste more to cook and never needed to ask me the same question — whether she will be able to see again.

Early diagnosis

IF you have diabetes and have not seen an ophthalmologist for the past one year, make an appointment now.
If you have any of these symptoms, it is even more important to do so:
• You cannot see well in dim light
• You have dark spots in your field of vision
• You are unable to focus and the vision is blurred and hazy
• You have double vision
• You see some spots floating in your field of vision
• You have pain in any one of the eyes which can be associated with headache
