I’ve never heard convincing information supporting the claim that canola oil is a healthy oil. The same goes for grapeseed oil and safflower oil. The local organic grocery store uses canola oil in almost all of their prepared foods…they use it like it’s going out of style! I’ve always felt a little twinge inside when I buy something containing these oils…a little voice saying “this is not right.” I know it sounds silly, but it’s true!
Is canola oil really healthy? Or is it bad news?
I found some science-based information in Max Lugavere’s new book “Genius Foods,” regarding seed oils, and it’s looking like canola oil is bad news.
In his book, Max Lugavere explains that there are 4 main types of oils, or fats, that we consume:
- saturated fat
- monounsaturated fat
- polyunsaturated fat
- trans fat
It is commonly known that #4 (trans fat) is really bad news, and people are now heeding the warnings enough to actively avoid trans fats, and food brands market their products with “0% trans fat!” labels.
But what about polyunsaturated fats? Canola oil, along with other seed or grain oils, such as corn oil, soy oil, safflower oil, and grapeseed oil, and I would guess pumpkin seed oil, are all polyunsaturated fats. Some claim that because polyunsaturated fats contain some omega 3 and omega 6 fatty acids, this means that polyunsaturated fats are safe, and even healthy to consume. Some claim that when comparing all of the polyunsaturated seed/grain oils, canola is the most healthy, because it has more omega 3 fatty acids than the others. But omega 3’s are unstable, and therefore they oxidize quickly and easily. Oxidation equals damage. Damaged oils damage the body by causing inflammation. There’s the first problem.
The second problem lies in the processing. We’ve had to develop machinery and chemicals to extract the oils from these seeds. And then, the deodorization process takes place, so that the oil is tasteless, and odorless, unlike good ol’ olive oil. Do we want oils that are tasteless and odorless? I know it can be convenient to use a tasteless and odorless oil to make mayonnaise, but is it really what we want? The human tongue is one of the most sophisticated set of sensors on the planet….we rely on our tongue to tell us if a substance has ‘gone bad,’ or if an oil has been damaged, or ‘gone rancid.’ If you make the oil tasteless, you’re taking away the ability to determine if the oil is rancid or not. That is very dangerous in my opinion – like I said — damaged oils damage the body.
In addition, the deodorization process CREATES trans fats! According to Max Lugavere, about 5% of grain and seed oils are trans fat!! Trans fat causes inflammation, and cancer.
I read that foods like grass fed beef, eggs, and fish have trace amounts of polyunsaturated fat, but these are trace amounts. When you think about the crackers or chips we buy in the snack aisle, we can see that we have left the ‘trace amounts’ train far behind. The seed oil is a large and important part of these foods, designed to activate the reward centers in our brains.
As a final note, I learned that roasted nut butters can also contain some unsavory/unstable polyunsaturated fat, so make sure you buy raw nut butters, or make them yourself.
Bust out the grass-fed and/or organic lard, tallow, duck fat, lamb fat, ghee, butter, coconut oil and whatever else is good and wholesome!
Be well,
