芥花油 (Canola oil) 欧洲已禁:别再吃了
加国无忧 51.CA 2013年3月3日 07:39 来源:博客 作者:郡妮 [ 加大字体 | 缩小字体 ] Canola 油的迷思与真相

大约是十几年前,市面上突然出现了一种新的烹饪油,英文叫做 Canola Oil 。起先只有在专卖 ” 健康自然产品 ” 的店裡才能看到,但是因为政府及私人公司都广为宣传这种油的好处:纯植物提炼、不饱和性脂肪、低胆固醇、比别的植物油还理想 … 云云。

既然连政府都这麽说,大概是不会错了;于是乎关心自己和家人健康的朋友,都纷纷买回去做菜。它在北美洲的销路直线上升,没多久也引进了台湾。

但是, Canola 油 到底是什麽东西做的呢?其他的油都可以从名字望文生义:如橄榄油,当然是橄榄的油;花生油是花生仁的油;椰子油是椰子果实的油 … 等等。笔者心生疑惑,查了极详备的东华大辞典,竟然没有这个字。

去年某日,笔者重听 雷博士在四、五年前演讲的录音带,赫然得到了答桉。正巧又有一位琉璃光的朋友,转来一篇网上有关此油的文章,恰印证了 雷博士所言。

笔者知道有不少朋友还在用这种油,当即转发此文给一些能看英文的朋友。数天之后,有一位本地朋友很急切的告诉我说: ” 好可怕啊!我们家这几年都用 Canola 油,那篇文章裡讲的症状我们一家四口全有!我已经马上换掉了! ”

英文 Canola 一字,是从 ”Canada Oil Low Acid” 四个字的首字母组合而成,意为 ” 低酸加拿大油 ” 。

Canola 的前身是一种叫作芸苔 (Rape) 的植物,原生地是欧洲,俗称欧洲油菜,属十字花科 (Mustard Family) 。

1970 年代,加拿大的科学家把芸苔作了基因改造,去掉裡面的糖 (Glycosides ,会干扰甲状腺功能 ) ,并减少其中所含的芥子酸 (Erucic Acid ,有毒 ) ,改良出了第一代的 ” 低芥子酸芸苔子 ” (Low Erucic Acid Rapeseed ,简称 LEAR) 。

但荷兰有研究显示,这种油会伤害心脏。 这项基因改造工程持续未断,所以也一直未有官方的长期追踪研究报告,但是由于这个新品种油菜容易种,长得快,虫害少 ( 虫子退避三舍 ) ,收成多,很快就变成了加拿大的主要经济作物。

加拿大人说,这种基因改造的菜籽油有 ” 二低一高 ” 的优点 ; 芥子酸低、糖低、好的油酸 (Oleic Acid) 高,又是不饱和脂肪,真是太理想的 ” 健康 ” 油了,不但鼓励自己人民吃,也不忘推销到好邻居美国去。

1979 年,加拿大的食用油工业,决定为它改名为 ”Canola” ,正式摆脱了 ” 有毒芸苔 ” 的阴影,并凸显加拿大之光。

加拿大人付了美国食品药物管理局 (FDA) 五千万美元,把 Canola 登记为合法,并认证为 ” 安全 ” 。于是美国农民也纷纷买种子回去种。这样一种经过基因变造的主要食用作物,美加政府未要求先作人体试验,就允许其在市场上大卖,吃进老百姓的肚子。当然,这也不是头一椿了。

加拿大曾用此油作动物实验,结果是这样子的:

老鼠的心、肾、肾上腺及甲状腺中的脂肪,产生变性和退化;而饲料中不加 Canola 油之后,老鼠体内这些累积的脂肪残渣就慢慢溶解,但是在那些主要器官上留下伤痕。

这是由于长鍊脂肪酸 (C22 ∼ C28) 不能为生物体吸收,累积在体内形成瘀塞,不但引 起 心血管问题,并且会破坏神经髓鞘 (Myelin) 。神经没有了这个保护层,就如同家中的电线外皮剥落,是很危险的事,而 Canola 油正是一种长鍊脂肪酸 (C22) 。

Canola 油会破坏神经系统,想来是不无道理,因为在二次大战中所使用的神经毒气芥子气,就是以芸苔为原料。在令数千军民的皮肤及肺起泡以后,早已禁用了。

根据油脂专家所作的研究及观察,食用 Canola 油的人出现了以下症状:

1. 视力模煳╱失明
2. 听力减退
3. 排尿不顺╱困难
4. 呼吸急促╱气短
5. 心脏病╱心律不整
6. 罹癌率增加
7. 便秘
8. 失眠
9. 小儿啼哭不止╱婴儿出生体重不足
10. 无名的疲惫

11. 干扰破坏神经系统,其产生的症状计有:
a. 发抖、颤动、麻痺
b. 走路、写字等动作不能协调
c. 口齿不清
d. 口水过多
e. 记忆及思考退化
f. 难以适应环境╱过敏 │ 如食物、气味、衣物、电器、气候冷热变化等
g. 神经崩溃
h. 手脚末梢麻木刺痛
i. 多重硬化症

1986 至 1991 年间,欧洲大量把芸苔菜籽加在牲畜饲料裡面,结果动物的眼睛失明,而且会攻击人。也就是在这段期间,发生了狂牛症 (Mad Cow Disease) 及羊痒病 (Scrapie) 。

而欧洲自 1991 年始全面禁用芸苔菜籽后,羊痒病就不复见,牛羊猪眼瞎、攻击人的情况也没有了。这是巧合吗?

儘管芸苔已摇身一变而为 Canola ,但是它其中的毒性仍未全消,它作为工业用润滑油的渗透性也还在。

有人作过简单的实验:把 Canola 油沾一些在布料上,用洗衣粉、清洁剂洗了三次,不但洗不掉痕渍,油渍上仍旧有油臭味。渗透力这麽强的油,到了人体裡面,会产生什麽效应? 加国无忧

不仅如此, Canola 油会形成乳胶状的物质,使红血球凝结成团。

1997 年,加拿大有一个很出名的研究,给实验小猪的饲料裡掺了 Canola ,结果发现其体内的维他命 E 值降到极低,已近危险程度。至于另一组吃黄豆油饲料的小猪,其维他命 E 值并未下降。因此证明 Canola 油会破坏体内的维他命E。

次年这一研究小组又发表新的实验结果,证实 Canola 油也会减少小猪体内的血小板数量,并且血小板的体积也变小了。

但是,你若去网上查有关 Canola 油的资料,仍会发现说它好的资料多。

美加的专家学者说,这些对人体的效应,在食用 Canola 油十年以后才会出现,所以不必太担心。

※※※※※※※※※※※※※※※※※※※※※※※※※※※※※※※

上述仅是 Canola 油本身独具的特性;除此之外,它也不免 经过了一般植物油的提炼过程,才能从菜籽变成一瓶清清如水的食用油。

这个过程大略是这样子的:

首先用己烷 (Hexane) 溶剂及别的化学剂,将油从菜籽裡分离出来,再以华氏 300 度的高温提炼,去掉芸苔子油天生的怪味。任何油经过这种高温都会变质,其中的 Omega-3 成分因此腐坏,而产生臭味。

下一步是把腐败的 Omega-3 的臭味去掉,将其氢化以保持其稳定,不易 ” 变坏 ” 。到了这个程度,油中好的成分已破坏怠尽,只剩馀对一些人体有害的物质。

所以 Canola 油是氢化油,其中所含的反式脂肪 (Trans-fat) 可能高达百分之四十。有关氢化油及反式脂肪会对人体造成什麽影响,在 陈俊旭博士所着的 ” 吃错了,当然会生病 ” 一书中讲解得非常清楚。

而今, Canola 油已无所不在,即使你不买来烧菜,它也已经在洋芋片中、在花生酱中、在饼乾中、在餐馆食物中 … 。如果您想避免它,那麽在选购食品时,要先看一看成份标示。

有时候表上并未明列含有 Canola 油 ( 或菜籽油 ) ,但是最后加了一句 ”… 以及其他油。 ” 那麽很可能就是 Canola 油了,因为它最便宜。

现代饮食确是危机四伏,有政府背书的也不能全信,所幸,我们还可以用自己的知识、直觉与智慧来判断。

尚有好些健康的油可供选择,如椰子油、橄榄油、葡萄籽油、红花油 (Safflower Oil) 等等,但是都须冷压榨取的才可以。

其中,又以椰子油是天然的饱和性植物脂肪,所含是中鍊脂肪酸,对人体最为适宜。至于饱和脂肪及不饱和脂肪究竟谁是谁非,这又是一个误导和迷思,有智慧的读者们多收集一些资料,多思维之后 ? A 便不难明了其中答桉。

在此且引申加拿大一位环保人士,托比.麦隆尼 (Toby Maloney) 的话作结尾:

要改变一般大众信以为真的事,真是不太容易。 Canola 油这整件事就是操控的结果 : 操控种子、操控农作、操控食品加工、操控期货市场。 ( 按:还要加上 ” 操控大众传播 ” ) 而因何得以如此矇蔽大众呢?根源就在于大多数现代人已不再亲自参与食物的生产了。这才是最不健康的事。

欧洲对gm food的管理比北美要严得多。
同理,这canola 这里还是合法的。:D

Canola oil is the healthiest of all commonly used cooking oils. It is lowest in saturated fat, high in cholesterol-lowering mono-unsaturated fat and the best source of omega-3 fats of all popular oils.

Canola oil comes from pressed canola seed. The seed is harvested from pods that are formed after those beautiful yellow flowers fade away. North American farmers have been growing canola seed for over 30 years.

Canola is not rapeseed. It looks the same on the outside but it's very different on the inside, where it matters. In the late 1960s, plant scientists used traditional plant breeding methods to get rid of rapeseed's undesirable qualities - erucic acid and glucosinolates. That means canola oil and meal are different from rapeseed oil and meal.


Canola was developed using traditional plant breeding techniques, so it was not developed using biotechnology. However, about 80% of the canola grown in Canada has now been modified using biotechnology to make it tolerant to some herbicides. Using these specific herbicides has reduced the amount of chemical needed for weed control in the fields.

Remember - the canola plant has been modified, not the oil. So canola oil from the herbicide tolerant plant is exactly the same safe and healthy oil as canola oil from conventional plants. The modification has been made to only one canola gene and it is a protein. Processing removes all proteins from canola oil. That means canola oil made from GM seed is conventional canola oil.


Yes. Clinical studies involving thousands of healthy volunteers have been conducted over the past 20 years. These studies examined the role of canola oil in lowering blood cholesterol levels and reducing risk of coronary heart disease, cancer, diabetes and high blood pressure.

The studies confirmed that when used as part of a balanced diet, canola oil has been shown to lower blood cholesterol levels and have a beneficial effect on clot formation, thereby decreasing the risk of heart disease and stroke.

Canola oil contains just 7% saturated fat compared to 15% for olive oil, 19% from peanut oil and 12% for sunflower oil.


Yes. Before being approved for food use, canola oil was required to go through stringent animal feeding trials to ensure it was a safe edible oil. A great deal of research has shown the benefits of incorporating canola oil into human diets.


No. Canola oil has been thoroughly tested and is guaranteed safe and beneficial for humans.

Hydrogenated rapeseed oil is also safe and is in fact approved by Canadian and US food regulatory agencies for use as a food product emulsifier. When rapeseed oil is fully hydrogenated, its erucic acid becomes behenic acid - a natural saturated fatty acid found in peanuts and peanut butter. Some peanut butter brands contain very small amounts of hydrogenated rapeseed oil to prevent the peanut oil from separating from the peanut butter.

Rapeseed is grown on very limited acreages in North America under contract between the grower and the buyer. It doesn't get into the regular grain handling system.


No. The FDA granted GRAS (Generally Recognized as Safe) status following the submission of a lengthy petition, which detailed years of research on the beneficial health effects of canola oil in human and animal diets.


Yes. Any plant-sourced oil such as olive, corn, soybean and flax can be used industrially to make lubricants, oils, fuel, soaps, paints, plastics, cosmetics or inks. In fact, any organic hydrocarbon (including ALL vegetable oils) can be processed and denatured to make industrial chemicals. Proteins in milk can be used to make glue. Wheat and canola can be used to make ethanol, and canola seed can be used to produce biodiesel.

But just because you can do this doesn't make the approved food oils at the grocery store somehow poisonous or harmful!


No. In fact, canola oil has good effects on your blood. Canola oil is a good source of alpha-linolenic acid or ALA, for short. ALA is an essential omega-3 fatty acid required in the human diet because our bodies cannot make it.

Animal and human clinical studies show that ALA has many of the same beneficial effects on blood clotting, platelet aggregation and the vascular system as omega-3 fatty acids found in fatty fish such as salmon and mackerel.


No. After extensive animal and human testing, canola oil has been proven to be absolutely safe to consume and will not produce these or any other diseases or conditions.


No. Canada's food processors use canola oil because their customers want healthy food.


No. Mustard gas is an oily volatile liquid that got its name from its mustard-like odour. It bears no relation to canola, or any other plant member of the mustard family.


Yes. However, the study also found that other vegetable oils tested in China produced the same emissions under the same conditions. Most people in China cook with unrefined rapeseed oil, which is not processed to remove contaminants and contains no antioxidants. Temperatures during wok cooking in China are about 100o F (38oC) higher than those used in Canada and the US. This combination of frying with unrefined rapeseed oil at very high temperatures (to the point where the oil produces a thick, black smoke) can produce harmful emissions.

Consumers in other countries use more refined vegetable oils - never rapeseed oil - at much lower cooking temperatures. These two factors prevent these emissions. All vegetable frying oils used in Canada and the US (and many other countries) are refined and frequently contain antioxidants that help prevent harmful emissions during frying.


No. Canola oil's shelf life stored at room temperature is about one year. Except for flaxseed oil, the shelf life of other vegetable oils stored at room temperature is similar. Flaxseed oil should be stored in the refrigerator.


No. There is no connection between BSE and canola oil.


Yes. Pour any cooking oil - canola, olive, corn, sunflower or peanut - over an insect and you'll suffocate it. Vegetable oils in general are recommended by many horticulturists as a non-chemical, more environmentally friendly insect control method.


No, canola does not contain cyanide. Canola contains compounds that sound a little like that - isothiocyanates, compounds found naturally in many foods, especially in cruciferous vegetables such as cabbage, Brussels sprouts, cauliflower, broccoli, kale, turnips and canola.

Isothiocyanates are sulphur-containing compounds that have anti-cancer properties - a fact first recognized some 30 years ago. In rats and mice, isothiocyanates inhibit the development of tumours in esophagus, mammary and lung tissue. Isothiocyanates appear to act by interfering with the metabolism of cancer agents and increasing their removal from the body. The cancer-fighting properties of cabbage, cauliflower and the other members of the mustard family are likely due to their isothiocyanate content.


No. Millions of organic compounds found on earth contain covalent bonds. Covalent bonds are those in which atoms share their electrons. There is nothing dangerous or harmful about covalent bonds. They are the glue that holds together most organic compounds, such as fatty acids, proteins, glucose and ascorbic acid (vitamin C).

When necessary, the body uses enzymes (types of proteins) to break the covalent bonds during normal metabolism. The fatty acids found in canola oil and all other fats and oils contain covalent bonds that can be broken by enzymes to create compounds used to produce energy or make hormones and other important compounds.


No. There is no evidence that canola oil depresses the immune system.

Glycosides are compounds formed from reactions involving alcohols and sugars such as glucose. Many compounds found in plants - flavourings, colors and steroids - occur as glycosides. Table sugar - or sucrose, as it is known chemically - is a glycoside, as is lactose or milk sugar and potato starch. So is salicin, the bitter-tasting glycoside obtained from willow bark and used by First Nations peoples many years ago to treat fevers and other ailments. Today, we use a related compound for the aches and pains of sore throats, colds and the flu - we call it ASA.

Glycosides are a key part of normal human metabolism. There is no evidence that canola oil depresses the immune system.


No. The European Union (EU) countries together produce more canola than Canada. Europeans call their canola "oilseed rape" - and call the oil "rape oil" or "rapeseed oil" - but it is canola. They chose not to adopt the new name "canola" when it was developed. So Europeans consume canola oil every day - and have ever since canola was introduced in Europe shortly after being developed in Canada.

The difference is that European farmers are prevented by law from growing genetically modified canola (or any GM crop). Europeans therefore consume canola oil from non-GM plants. Most of the canola oil from Canada can be exported to the EU and the EU has also approved some of the GM canola seed for processing.

Canola oil produced from GM plants is safe and healthy. And canola oil itself does not contain any GM ingredients. The GM modification is made to one canola gene and it is a protein. All proteins are removed from canola oil during processing so canola oil made from GM plants is no different from conventional canola oil.
 
公说公有理婆说婆有理。如果生活中什么事都听专家的,那得让人纠结到死。
 
这么多年,Canola Oil用得不算多。

我是各类油换着吃。

canola oil banned in eu不是新闻,都好几年了
啥时候banned in north america 才是新闻。
一个月吃不了多少油的,君子不立于围墙之下,大把的选择。

自己家的餐桌好控制,可是购买加工过的食物就太难控制了,只要加拿大政府不禁这油,它的价格又低,食品加工过程中就少不了它。这不,刚从COSTCO买的杏仁饼干,都犹豫要不要吃了。:crying:
 
送给我吧,为你解忧:D:D

吃了油,多长时间能出现那些症状?
好像我周围的人都没有。
 
反正这油不是好东西
 
好象印象中没吃过这种油。:blink::p
 
欧洲并没禁止,且种植量远大于加拿大,只是要求注明是“转基因”油。这些中文网站转贴的文章,常常是断章取义,缺乏公正全面。
