Canola Oil is not all it's said to be. Currently, it is marketed as a heart healthy oil because it falls into the category of a polyunsaturated fat.
Canola Oil is made from rapeseed oil. The name comes from 'Canada' and 'oil'. According to AgriAlternatives, a magazine for farmers, "By nature, these rapeseed oils, have long been used to produce oils for industrial purposes, are toxic to humans and other animals." It's used in insect repellent and synthetic rubber. And if you see the word Canola Seeds - this is just marketing. It's just a name change from rapeseed. It's the same seed.
Because it is a highly refined, processed food product, the body cannot break it down and use it for nutritional fuel in the body. Sure, it has a high heat tolerance, but so does the oil in your car.... It may be heart healthy and polyunsaturated, but anytime the body ingests a fragmented food product, it is missing nutrition - that simple.
Some clinical studies are showing permanent scarring of the kidneys, heart, adrenals and thyroids in animals when given canola oil. More clinical trials have been done showing a relation to growth retardation, deficient blood platelet, high blood pressure, stroke and allergies.
Although the oil may be toxic, I would not blame these conditions solely on this one product. Look at the whole enchilada - most processed, refined foods use canola oil in their manufacturing processes because of cost, shelf life and marketing. It's a lifestyle contributing to disease. A lifestyle that encourages stress, a fast pace, eating on the run and not listening to the body.
So, what can you do instead? Use extra virgin olive oil, unrefined sesame oil, red palm oil, coconut oil and plain old butter. Use fat/oils the way God created them. When the whole of the nutrient is present, the body knows what to do with it. When you eat a fragmented food, which is usually a processed food, you are missing vital nutritional pieces for the whole of your body.
Whole food = whole body. Do you want to be defined in fragments or as a whole?
