It is difficult to see how an article "debunking" the dangers of canola oil can have any legitimacy when it appears on a page that is branded with a buy canola oil banner advert, a buy canola oil background image as well as a buy canola right pane advert.

The article that roundly pooh-poohs the dangers of canola oil, ends with this beauty: "Food myths may also be spread by individuals who are paid to discredit such foods by the manufacturers of opposition products."  Now for R 1 million, can you guess who could have been paid to credit the product on this page!

The article in question appears here:

With all due respect Dr Albrechts sweeping dismissal of the dangers of Canola oil are a little too glib for my liking.

As he rightly says, rapeseed oil has been used for many years. In fact rapeseed oil has been used for thousands of years because it is so easily extracted from the seeds. Old methods involved pressing out the oil at room temperatures. 

However modern methods do no such thing. The process uses high pressures, high temperatures and washing with a chemical solvent (normally hexane) to extract the maximum amount of oil from the seeds. The extracted oil is then washed with caustic soda to remove impurities. A further cooling process removes wax. Then the oil is bleached and finally deodorized with a stream injection process to remove the canola odour. You can watch a production video made by the Canola manufactures here: Producing Canola Oil Video  

Contrast this heavy handed industrial process with how cold pressed olive oil is made. A process where heat is rigorously controlled not to go over 27 degrees centigrade and modern centrifugal methods are employed specifically to avoid high pressures. And NO CHEMICALS are needed to extract the oil. 

Which oil would you chose to put in your body?


Another issue that is avoided, is the fact that most of the seeds used to make canola oil are “herbicide tolerant”. This is the polite name for crops that have been genetically modified to tolerate unusually high doses of poison, usually glyphosate (Roundup). By 2009 a survey found that 90% of the Canadian crop is genetically modified in this way and a 2005 study found 87% of the US crop be similarly modified. GMO canola is legal in Australia and is the country’s third largest crop. So that means you get more glyphosate residue in your oil. (Glyphosate is acknowledged to the EPA in the US to have to potential to cause kidney and have reproductive effects.

Medical Studies 

As he says in his article, Dr Albrecht did systematic research into the international scientific literature looking to debunk the canola myths, many of which are surely overblown and exaggerated. 

However he may have missed a some research papers that point to canola being toxic to the cardiovascular system. Studies show that (in rats) canola oil causes also vitamin E deficiency and can affect blood components like platelets. An alarming 2003 Japanese study found that the high blood pressure enhancing effects of canola oil resulted in a significant lifespan reduction in specially bred rats that were fed with canola oil as opposed to soybean oil.    (


Despite his well-meaning wish to debunk the popular myths of the dangers of canola oil, I believe that there is more than enough credible evidence to suggest that my body is not the best place to dispose of canola oil. 

I would far rather throw it down the drain where it would find a good home among the other nasties living there.
