Canola Oil - How Toxic Is It?
Canola is a coined word. It appeared out of nowhere and is not listed in any but the most recent reference sources.
The flip side of the canola coin reads: "rape"! You must admit that canola sounds better than rape. The name canola disguised the introduction of rape oil to America.
Canola oil comes from the rape seed, which is part of the mustard family of plants. Rape is the most toxic of all food-oil plants. Like soy, rape is a weed. Insects will not eat it; it is deadly poisonous! The oil from the rape seed is a hundred times more toxic than soy oil.
Canola is a semi-drying oil that is used as lubricant, fuel, soap and synthetic rubber base, and as an illuminant for the slick color pages you see in magazines. It is an industrial oil and does not belong in the body!
Canola oil has some very interesting characteristics and effects on living systems. For example, it forms latex-like substances that agglutinate the red blood corpuscles, as does soy, but much more pronounced. Loss of vision is a known, characteristic side effect of rape oil which antagonizes the central and peripheral nervous systems, again like soy oil, again worse. The deterioration takes years, however. Rape (canola) oil causes emphysema respiratory distress, anemia, constipation, irritability and blindness in animals-and humans. Rape oil was widely used in animal feeds in England and Europe between 1986 and 1991 when it was thrown out. You may remember reading about the cows, pigs and sheep that went blind, lost their minds, attacked people and had to be shot.
In the reports I read, the "experts" blamed the behavior on a viral disease called scrapie. However, when rape oil was removed from animal feed, "scrapie disappeared.
No longer a European livestock problem; now it is ours. U.S. farmers grow rape seed, and manufacturers use its oil (canola) in thousands of processed foods, with the blessings of government watchdog agencies, of course.
Rapeseed oil was a monounsaturated oil that had been used extensively in many parts of the world, notably in China, Japan and India. It contains almost 60 percent monounsaturated fatty acids (compared to about 70 percent in olive oil). Unfortunately, about two-thirds of the mono-unsaturated fatty acids in rapeseed oil are erucic acid, a 22-carbon monounsaturated fatty acid that had been associated with Keshan’s disease, characterized by fibrotic lesions of the heart. In the late 1970s, using a technique of genetic manipulation involving seed splitting,2 Canadian plant breeders came up with a variety of rapeseed that produced a monounsaturated oil low in 22-carbon erucic acid and high in 18-carbon oleic acid. The new oil referred to as LEAR oil, for Low Erucic Acid Rapeseed, was slow to catch on in the US. In 1986, Cargill announced the sale of LEAR oil seed to US farmers and provided LEAR oil processing at its Riverside, North Dakota plant but prices dropped and farmers took a hit.3
MARKETING LEAR
Before LEAR oil could be promoted as a healthy alternative to polyunsaturated oils, it needed a new name. Neither “rape” nor “lear” could be expected to invoke a healthy image for the new “Cinderella” crop. In 1978, the industry settled on “canola,” for “Canadian oil,” since most of the new rapeseed at that time was grown in Canada. “Canola” also sounded like “can do” and “payola,” both positive phrases in marketing lingo. However, the new name did not come into widespread use until the early 1990s. An initial challenge for the Canola Council of Canada was the fact that rapeseed was never given GRAS (Generally Recognized as Safe) status by the US Food and Drug Administration. A change in regulation would be necessary before canola could be marketed in the US.4 Just how this was done has not been revealed, but GRAS status was granted in 1985, for which, it is rumored, the Canadian government spent $50 million to obtain.
Modern oil processing is a different thing entirely. The oil is removed by a combination of high temperature mechanical pressing and solvent extraction. Traces of the solvent (usually hexane) remain in the oil, even after considerable refining. Like all modern vegetable oils, canola oil goes through the process of caustic refining, bleaching and degumming—all of which involve high temperatures or chemicals of questionable safety. And because canola oil is high in omega-3 fatty acids, which easily become rancid and foul-smelling when subjected to oxygen and high temperatures, it must be deodorized. The standard deodorization process removes a large portion of the omega-3 fatty acids by turning them into trans fatty acids. Although the Canadian government lists the trans content of canola at a minimal 0.2 percent, research at the University of Florida at Gainesville, found trans levels as high as 4.6 percent in commercial liquid oil.24 The consumer has no clue about the presence of trans fatty acids in canola oil because they are not listed on the label.
A large portion of canola oil used in processed food has been hardened through the hydrogenation process, which introduces levels of trans fatty acids into the final product as high as 40 percent.25 In fact, canola oil hydrogenates beautifully, better than corn oil or soybean oil, because modern hydrogenation methods hydrogenate omega-3 fatty acids preferentially and canola oil is very high in omega-3s. Higher levels of trans mean longer shelf life for processed foods, a crisper texture in cookies and crackers—and more dangers of chronic disease for the consumer.
