• Canola oil from the rape seed, referred to as the Canadian oil because Canada is mainly responsible for it being marketed in the USA. The Canadian government and industry paid our Federal Food and Drug Administration (FDA) $50 million dollars to have canola oil placed on the (GRAS) List "Generally Recognized As Safe" . Thus a new industry was created. Laws were enacted affecting international trade, commerce, and traditional diets. Studies with lab animals were disastrous. Rats developed fatty degeneration of heart, kidney, adrenals, and thyroid gland. When canola oil was withdrawn from their diets, the deposits dissolved but scar tissue remained on all vital organs. No studies on humans were made before money was spent to promote Canola oil in the USA.

• 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 (SOY OIL IS NEXT ON THE LIST!). 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!

• The Canadians are condemning any oil that contains essential fatty acids. EFAs cannot stand heat. They turn rancid quickly. Proper processing, i.e., cold pressing, and protection from oxygen for storage is paramount with EFAs. Mainstream toxic commercial food making requires complete removal of EFAs lest shelf life disappear in smelly rancidity. Absent the removal of EFAs, few manufactured toxic chemical foods would make it out of the warehouse. So, here we have Canadians telling us that their country's main oil export kills little animals. They suggest that perhaps it was the health giving EFAs left in the canola oil after it had been scorched at temperatures above 300 degrees farenheit to get rid of the EFAS. They don't tell you that whatever EFAs are left in the oil, are now poisonous rancid fats. It may be that the now toxic remnants are what's killing the vitamin E, and killing the little piggies. I think the Canadians produced that deceptive half truth to protect their careers from grant drought.
