Few things get me as fired up as seeing companies, doctors and governmental organizations recommending canola oil (or just bad nutrition/health advice in general).

Just today, an awesome reader emailed me to show me the response the company she was using as a meal replacement shake:

This company told her that canola oil is one of the healthiest oils available because it contains both omega-3 and omega-6 and it’s the “best oil to do this.”

Let me be clear: this is total bulls*t.

This is something that people always say when I highlight the fact that canola oil is an industrialized, rancid oil. Company after company uses this oil for one reason – because it’s cheap. But they fool people who use and sell their products into thinking that this oil is healthy when in reality it’s anything but.

And even worse, our own government recommends this oil over fats that are actually healthy, like butter.

I’m here to clear up to confusion and tell the truth about canola oil. Let’s start with the facts, shall we?


Plant breeding created the rapeseed, the source of canola oil. Industrial purposes were the intent even in ancient civilizations. But people soon realized the popularity of the plant for industrial purposes was failing and needed to reinvent it to upkeep cash flow. Unfortunately, the majority of the monounsaturated fatty acids in rapeseed were made up of erucic acid, which has been associated with Keshan’s disease. Keshan’s disease causes fibrotic lesions on the heart.

Canadian scientists selectively bred the rapeseed to produce low erucic acid. The name canola oil comes from Canadian oil, low acid.

In 1995, Monsanto introduces rapeseeds genetically manipulated to withstand the toxic herbicide RoundUp. Which leads me to my next point.


It’s been estimated that up to 90% of canola crops are genetically modified. Why is this an issue? For starters, the World Health Organization has labeled glyphosate as a probable carcinogen.

Genetically modified food has been linked to infertility, cancer, aggression, allergies and even tumor growth. A French Study was conducted involving 200 rats and spanned two years; most studies on GMOs span 90 days. The study involved feeding the rats Roundup Ready corn.

“50 percent-80 percent of the females  had developed large tumors compared to 30 percent in the control group.” As for males, “Liver congestions and necrosis were 2.5 to 5.5 times higher than in the control group … [and] there were also 1. –2.3 times more  instances of ‘marked and severe’ kidney disease.” Overall, among the  rats receiving GMO and/or Roundup, “Up to 50 percent of males and 70 percent of  females died prematurely, before deaths could be put down to normal aging, compared with only 30 percent and 20 percent in the control group.” Source

The rats also developed severe tumors.


Just in case you doubt this study, the scientists who performed it were publicly smeared and attacked by the biotech industry, but recently won a defamation lawsuit and were vindicated.


This video is ridiculous in so many ways. It starts out by saying that canola oil is the healthiest oil because it contains the lowest amount of saturated fat and has omega-3s, which is wildly untrue. They go on to show how the disgusting process. I will never be able to understand how anyone thinks that a product (not a food) undergoes this amount of processing and is healthy.

To summarize the video:

The rapeseeds are firstly highly pressurized, forcing out the oil. To extract the remainder of the oil, the canola cakes undergo a 70-minute wash with a “chemical solvent.” This chemical solvent, my friends, is hexane. A neurotoxin. Then the oil enters the refining phase, in which the oil is washed with sodium hydroxide, aka lye. After this, the oil is clearer but still contains waxes. Then the oil is cooled to 41 degrees to filter out the wax – which is used for vegetable shortening. After this, the oil is bleached to remove the color, then “sue a steam injection heating process to remove the odor.” It’s heated to extremely high temperatures because the oil is literally rank and smells terrible.

In what world is this healthy? Am I taking crazy pills? Trust cows over chemists, ya’ll.


Now, I’m all about facts. You can say what you want, but I want the evidence. It’s what I rely on. It’s how I make my decisions. So any person, company or organization can say canola oil is healthy, that it’s anti-inflammatory, that it has a great omega-3 to omega-6 ratio. But here’s the truth.

One tablespoon of canola oil contains 2,610 mg of omega-6 fatty acids and 1,279 mg omega-3 fatty acids. That’s a lot of omega-6, which causes inflammation. While it’s true that our bodies need omega-6, it’s ubiquitous. It’s in everything, and Americans get way too much of it, which not only causes inflammation but leads to heart disease and cancer. Proponents of canola oil love to tout the omega-3 to omega-6 ratio, but it’s still a lot of omega-6 and the omega-3s found in canola oil aren’t even beneficial (as opposed to omega-3s found in foods like fish).

Let’s further analyze this.

The omega-3s found in canola oil are ALA, alpha lipoic acid. ALA does not convert well to EPA or DHA. These are the beneficial omega-3s that protect the brain, heart and cardiovascular health while reducing inflammation. So promoting the omega-3 content in canola oil is redundant – the omega-3s in canola oil do not contain the beneficial EPA and DHA.

People love to tout canola oil as healthy because it’s low in saturated fat. But saturated fat is healthy! Like any fat, you want to obtain it from a good, healthy source. For example, grass-fed butter, pastured lard, organic coconut oil, etc. These fats are incredibly stable. They’re rich in vitamins or in coconut oil’s case, rich in health-promoting substances like medium chain triglycerides and lauric acid. There’s literally no compelling, legitimate evidence that diets high in properly sourced saturated fats cause health issues.

From the Oakland Research Institute at Children’s Hospital,

“A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD. More data are needed to elucidate whether CVD risks are likely to be influenced by the specific nutrients used to replace saturated fat.”


To conclude, canola oil is a rancid, highly processed industrial oil. The amount of processing it undergoes alone should give anyone pause. Furthermore, the nutrient profile of this oil is anything but healthy.

  1. Thank you for this. In South Africa canola oil is actually sold with the “Heart Foundation” seal of approval on the label. It’s criminal!
    I’m curious, which company are you referring to in the beginning of your article? I know Herbalife also has rapeseed oil in their meal replacement shake. Terrible!

  2. Lori DeBell Reply

    YES! Do you even know how much I love you for this? Your quick response to the product ingredients in Yevo and your back and forth emails with me shows such passion and knowledge! Dani, you are one of a kind and the ability to call it like it is also screams volumes! Stay blessed and keep informing! XOXO

  3. Is the cold pressed version also unhealthy ?? I’ve been given a bottle as a gift but scared to use it, I always use olive oil or butter usually.

  4. My dad is prescribed rapeseed oil capsule. He is 74 , had a successful bypass

    After reading ur article, I guess I will go for soyabean seeds. We try to avoid fish oil as we r vegetarian. But if soyabean also does not give omega3 /.6 , we will eat fish oil capsule.

    Any suggestions, my email id is [email protected]

      Soybean is even worse, fish oil is really the best option.

    • If your vegetarian and want omega 3s you can try Algae oil. This oil is derived directly from algae. This oil contains DHA, which accounts for 97 percent of the omega-3 fats in the brain. I would also still recommend watching the amount of fat because high intake of coconut oil or butter can still increase your LDL cholesterol which has been show to increase risk of CVD. Personally I like to use avocado oil as it has a high smoking point.

  5. I was under the impression Canola was healty thank you for your article. What is the best oil to use?

  6. What is it in the final product (canola oil) that is not good. This is a very silly comment to label all canola oil as poison. Take a bottle of canola oil to a reputable lab and get it annilized,compare it to all other oils. It is irresponsible to place comments like this. Think about the farmers and all the people involved before placing such comments. Are they all out to kill us and all the food regulating bodies turning a blind eye, surely not.
    canola farmer, using it every day,

  7. You may want to do some more research on GMOs. Not only are they completely safe. We’ve been using them for ever. Plenty of studies have concluded absolutely zero issues with their ingestion. You honestly sound like an anti-vaxxer who read one article on Facebook and now feels they need to tell the world they cause autism (hint: they don’t). At least in this case, you paying 20-40% more for non-gmo foods doesn’t impact anyone but yourself. But just as a reminder, remember that without GMOs there would be widespread food shortages. Are you promoting the starvation of children? For what? Some pointless hits on your blog?

    Don’t let your blind ambition continue this pointless campaign of misinformation.

  8. But what about organic expeller pressed canola oil? all the rat studies and negatives are from conventional canola oil.
