“Canola oil, which comes from the seed of the rape plant (it is known as rapeseed oil in other countries), is poisonous to many living things. It is used as an insect repellent and was the source of the chemical warfare agent mustard gas, which was banned after it was shown to blister the lungs and skin of many soldiers. The name ‘canola’ comes from the fact that rapeseed oil was modified in a Canadian laboratory into a lower-acid oil presumed safe for human consumption (the word ‘canola’ stands for Canadian oil low acid). The Canadian government paid the U.S. Food and Drug Administration (FDA) a large sum of money to have canola oil placed on the ‘Generally Recognized as Safe’ (GRAS) list. However, studies of the effects of canola oil on lab animals show problems related to the heart, adrenals, kidneys, and thyroid. No human studies were performed before canola oil was widely promoted in the United States.

“When baking, I used to use organic butter and canola oil. I have now switched for all of my baking to a blend of organic butter and organic coconut oil. Coconut oil and butter, because they are saturated fats, are stable at high temperatures and remain stable for the extended time needed for baking. The damage done by oxidation of fats usually occurs when heating a relatively unstable fat such as a monounsaturated or polyunsaturated fat. Using a  monounsaturated fat such as canola oil [and olive oil] in baking or cooking leaves the body more susceptible to oxidative damage. An unsaturated fat, when heated, has the potential to convert into a trans fatty acid, which the body is unable to metabolize.”

“The name “canola” was registered in 1979 by the Western Canadian Oilseed Crushers Association to describe “double-low” varieties. Double low indicates that the processed oil contains less than 2% erucic acid and the meal less than 3 mg/g of glucosinolates. Erucic acid is a fatty acid that has been related to heart disease. Glucosinolates have breakdown products that are toxic to animals. Both characteristics make rapeseed products poor candidates for animal consumption.”
