Is Canola Oil Bad for You?

Canola oil may be good for you, according to some studies. The question is whether or not it’s the healthy kind of oil that we think it is.

Canola oil is a vegetable oil that has been widely used in the United States and Canada. It’s made from rapeseed, a type of canola plant, and it has become popular for its high smoke point and neutral flavor. However, the European Union banned canola oil because they believe it’s unhealthy because of the high erucic acid content (a fatty acid).


Is canola oil beneficial or harmful to your health? Some individuals consider canola oil to be a healthy diet, while others avoid it at all costs. Unfortunately, it might be difficult to get to the bottom of things when there are two really impassioned points of view.

On the one hand, opponents allege that canola oil is utterly hazardous, includes “the notorious chemical warfare weapon mustard gas,” and causes everything from mad cow disease to blindness. On the other hand, supporters think that canola oil is one of the healthiest oils on the earth and that it provides canola oil advantages due to its high omega-3 content, low saturated fat content, and high oleic acid content.

On the surface, these characteristics are correct, but there is much more to the canola tale.

What’s the deal with canola oil? Canola oil is a genetically engineered product that the Canadian government supports, is inexpensive to produce, and is used in many packaged or processed goods.

Canola oil was initially developed as a natural oil in the early 1970s, but Monsanto developed a genetically engineered version in 1995. In 2005, 87 percent of canola farmed in the United States was genetically modified, while 90 percent of canola grown in Canada was genetically modified by 2009.

It’s tough to sort through what’s true, what’s not, and, most importantly, which oil is the healthiest to use, with so many oils on the market and so much debate about the various kinds of oil. So I’m going to go over all the reasons why canola oil isn’t something you should buy, from genetic manipulation to an excess of bad fats — as well as better options and resources to help you avoid GMOs in general.

What Is Canola Oil and How Does It Work?

Rapeseed oil is extracted from the seeds of the rape or rapeseed plant, which belongs to the mustard (Brassicaceae) family. So, what exactly is canola?

In Canada, Keith Downey and Baldur R. Stefansson of the University of Manitoba were the first to breed canola from rapeseed in the early 1970s.

Genetic manipulation was used to create “the most disease- and drought-resistant canola variety to date” in 1998, and this is how the bulk of modern variations are generated.

Is canola oil considered a vegetable oil? Yes, since it’s a form of vegetable oil, it’s also referred to as this.

What is the origin of canola oil? Canola is a plant that produces canola oil.

Because wild rapeseed oil contains high quantities of erucic acid, which is known to cause health concerns, the canola plant was bred from rapeseed to produce a food-grade canola oil with reduced levels of erucic acid.

LEAR (low erucic acid rapeseed) was the original term for canola oil, but it was changed to canola oil for commercial considerations. This term was created by combining the words “Canada” and “ola,” which means “oil.”

Although canola oil has a more appetizing name than LEAR or rape oil, should you use it in your cooking?

Because canola oil is very inexpensive, it’s not unexpected that it has a wide range of applications. Candles, soaps, lipsticks, lubricants, inks, biofuels, and even pesticides have all utilized the oil as industrial oil.

Rapeseed oil started to be promoted as an edible food product once the powers that be found out how to engineer it genetically.

As a result, it has been marketed as a “miracle oil” that is low in saturated fats and high in omega-3 fatty acids. However, it may create a slew of health problems in its present hybridized and modified condition, as you will soon discover.


When the food industry started looking for healthful and cost-effective replacements to saturated fats in oils, canola oil was created. The American Heart Association and other US government organizations had circulated information that saturated fats, typically present in regularly used cooking oils, were detrimental to your heart health, bringing these saturated fats to the public’s notice.

Many of these studies focused on maize oil and soybean oil in particular.

Rapeseed oil was found after food makers explored and tested. Rapeseed oil is made mostly of monounsaturated fats.

The initial form of rapeseed oil had a high erucic acid content, which was an issue. Erucic acid is a fatty acid present in rapeseed and mustard oils that has been related to heart illness, namely Keshan disease, which is characterized by fibrotic heart lesions.

Food makers continued to refine rapeseed and canola oils until the late 1970s when they devised a technique for genetically manipulating the rapeseed plant by seed splitting. This seed split oil yielded canola oil with lower erucic acid levels and greater oleic acid levels.

LEAR was the name given to this oil at the time.

Although canola oil does not contain the formerly high quantities of erucic acid, there are still reasons to be concerned if you use it.

What is the process of making it?

To utilize the trademarked “canola” term, the sole component in canola oil is canola oil, containing less than 2% erucic acid and fewer than 30 micromoles of glucosinolates.

What is the composition of canola oil? It’s manufactured from the oil obtained by crushing the seeds of the canola plant to extract the oil content.

Each teeny-tiny contains roughly 42% to 43% oil. Animal feed is typically made from leftover canola meals.

Canola oil is manufactured in a variety of ways. It’s one of the numerous vegetable oils that go through the refinement, bleaching, and deodorization process.

The oil is chemically extracted from the seeds using hexane as a solvent.

Is it true that canola oil spoils? Unopened bottles have a two-year shelf life before they go bad.

According to most authorities, an unsealed oil bottle will get rancid in a year or less.

Nutritional Information

You’re undoubtedly curious about the nutritional value of canola oil.

Is canola oil beneficial to your health? The key to understanding the health attributes of canola, like with any food, is to look at the complete nutritional profile, not just one or two components.

A cup of canola oil comprises approximately:

  • Calorie count 1,927
  • 218 g of fat
  • 16.1 grams of saturated fat
  • Other studies suggest that it has significantly higher than 0.9 grams of trans fat.
  • Vitamin K (155 micrograms) (194 percent DV)
  • Vitamin E, 38.1 milligrams (190 percent DV)

As you can see, canola oil has a lot of calories. According to a research published in the Journal of the American Dietetic Association, the hydrogenation process hardens most canola oil used in processed foods, introducing up to 40% trans fatty acids into the finished product.

When you look at the whole fatty acid composition of canola oil, you’ll see something like this:

  • Saturated fat: 16.1 grams
  • 138 grams monounsaturated fat
  • 61.4 grams of polyunsaturated fat
  • 5,018 or 19,921 milligrams of omega-3 fatty acids, depending on the source
  • 40,646 mg of omega-6 fatty acids

Is canola oil dangerous for you? During my investigation, I discovered that most canola oils had a poor omega-3/6 ratio of 8:1 and a lot of trans fats, with just one source stating it was closer to 2:1. (the first number being omega-6s and the second the omega-3s).

Many individuals consume too many omega 6 fatty acids and not enough omega 3 fatty acids in their diet. One of the causes for this might be the increased intake of vegetable oils such as canola.

What Makes Canola Oil Dangerous?

Rapeseed oil may not have had as many harmful health impacts in the past.

Why is canola oil so harmful to your health? Most canola oil on the market today is potentially detrimental to your health for three reasons:

  1. First, canola oil is genetically engineered more than 90%.
  2. Canola oil is a refined oil that is often partly hydrogenated to boost its stability, but this has the unintended consequence of increasing its bad health consequences.
  3. In animal studies, it’s been linked to increased inflammation, and persistent inflammation is thought to be at the basis of most disorders.

For these two reasons, I advise you to switch to one of the healthier oil options listed below.

What harm may it cause you? There has been no long-term, credible research on GMO canola oil, although it has been said to cause renal, liver, and neurological problems.

This seems reasonable, given that GMO items like maize and soy have been linked to health problems in the past. So, if you’re deciding between soy or maize oil and canola oil, I’d recommend avoiding them altogether!

Is vegetable oil harmful to your health? Fat specialists Sally Fallon and Mary Enig, as well as the Weston A. Price Foundation, say:

Like other contemporary vegetable oils, Canola oil is refined, bleached, and degummed, all of which entail high temperatures or chemicals of uncertain safety. Canola oil must also be deodorized since it contains a lot of omega-3 fatty acids, which are readily rancid and foul-smelling when exposed to air and high temperatures. By converting omega-3 fatty acids to trans fatty acids, the typical deodorization method eliminates a major amount of them. Although the Canadian government lists the trans content of canola as being as low as 0.2 percent, studies at the University of Florida in Gainesville discovered trans levels as high as 4.6 percent in the commercial liquid oil. Because trans fatty acids are not indicated on the label, the customer is unaware of their existence in canola oil.

Monsanto has been known to use genetically modified organisms in its canola oilseeds, and we now know that the company has also sold GMO seeds for the following plants:

  • Canola
  • Alfalfa
  • Corn
  • Cotton
  • Soybeans
  • Sorghum
  • Sugar Beets
  • Wheat

When it comes to food containing genetically modified components, some progress was achieved in 2016. First, the president signed a bill modifying the Agricultural Marketing Act of 1946.

As a result, businesses must now declare the existence of GMO components using text labels, symbols, or digital links, as required by law (like scannable QR codes).

Sounds fantastic, but the issue is that the secretary of agriculture is in charge of determining what levels of GMO components must be included in a food product for the GMO labeling legislation to be mandatory.

The Top 6 Risks

1. Problems with the Kidneys and Liver

The bulk of today’s canola oil is genetically engineered. However, the negative consequences of genetically modified organisms, in general, cannot be emphasized.

19 studies of animals fed GMO soybeans and maize were assessed in a 2011 review published in Environmental Sciences Europe. The GMO foods caused liver and renal issues in the 90-day studies.

The results were really differed by sex, with the kidneys affected by 43.5 percent in male animals and the liver damaged by 30.8 percent in female mammals.

Because our kidneys and liver are so important to our survival, swallowing a genetically engineered product like canola oil is not something to be taken lightly.

2. A Life-Threatening Heart Condition

Rapeseed oil contains a lot of erucic acids since it’s a monounsaturated oil. Erucic acid is a fatty acid linked to heart disease, notably Keshan disease, a condition characterized by fibrotic lesions in the heart.

According to research, not only are selenium levels lower, but erucic acid levels are greater in locations where individuals are prone to Keshan.

Canola and other partially hydrogenated vegetable oils are known to cause artery inflammation and calcification, both of which are well-known risk factors for coronary heart disease.

3. Strokes and Hypertension

Consumption of rapeseed oil and other forms of vegetable oils has been demonstrated in previous research to reduce the lifespan of stroke-prone and hypertensive animal models. Rats designed to have high blood pressure and proneness to stroke died sooner when given canola oil as the main source of fat, according to a study conducted at the Nutrition and Toxicology Research Divisions of Ottawa.

Furthermore, rats given non-canola oil meals survived longer than rats fed canola oil diets.

Another research published in Toxicology Letters in 2000 looked at the effects of canola oil on blood coagulation time, or how long blood takes to coagulate, in stroke-prone animal models. The research discovered that “canola oil-induced shortening of blood coagulation time and increased fragility in [red blood cell membranes]” may enhance the risk of stroke in stroke-prone animal models.

4. It may slow down normal growth

Canola oil was not allowed to be used in newborn formula until recently. This is because canola oil has been linked to stunted development in children, which I believe is a genuine issue.

Newborns are at risk because of their inability to effectively break down the erucic acid in canola oil. Canola oil was previously declared prohibited in infant formula by the FDA.

On the other hand, Canola oil was added to the generally regarded as safe list a few years ago.

Not only is it dangerous to feed GMO oil to growing children, but it’s also dangerous to give them bad fats. Canola’s proponents boast about the oil’s overall healthy fat profile, but I’m not convinced.

It’s now available in the shape of a baby’s first meal. But, of course, if you are able, I strongly advise you to avoid commercial formulas and instead nurse your child.

5. Increases the intake of trans fats, which are unhealthy

When soybean and canola oils bought in the United States were analyzed, “the trans levels ranged between 0.56 percent and 4.2 percent of the total fatty acids,” according to a research published in the Journal of Food Lipids.

When canola oil is hydrogenated, as it typically is to produce a partially hydrogenated oil, the number of trans fats in the oil rises, these are a category of fats you should avoid as much as possible since they’ve been shown to raise LDL cholesterol and reduce HDL cholesterol in studies.

Trans fats have also been linked to weight increase in studies. Even when compared to the same calorie intake, trans fats caused weight gain in an animal research.

With the obesity pandemic we’re facing, it’s a good idea to rethink these oils in order to assist restore healthy weight and metabolic function; however, they’re just half of the issue.

When you see “partially hydrogenated oil” on a food label, you can be sure there’s some trans fat in there. Even though the label claims that there is no trans fat, this is accurate.

How is it possible? If a serving has less than 0.5 grams of trans fat, the firm is authorized to state that there are no trans fats in the product. I know it’s aggravating.

Trans fatty acids are dangerous food manufacturing byproducts that are true health killers. Therefore, if you decide to stop using canola oil, I recommend that you also stop using maize oil, safflower oil, soy oil, and vegetable oil.

6. Numerous Health Consequences of Genetically Modified Organisms

The relationship between GMOs and bad liver and renal effects has previously been recognized, but it doesn’t end there. According to the Center for Food Safety, scientific study has discovered numerous new and extremely significant health risks and unforeseen repercussions of genetic engineering:

  • Toxicity
  • Reactions due to allergies
  • Immuno-suppression
  • Cancer
  • Nutritional Deficit


There are considerably better alternatives to “vegetable” oils, which seem to be healthful but are everything but. The majority of vegetable oils (canola, maize, peanut, safflower, and so on) are derived from genetically modified crops and/or are highly refined.

So, what are the greatest cooking oils? Here are some of the top oils I use as a canola oil substitute:

1. Coconut Oil

Is coconut oil harmful to your health? If you’re seeking a healthy option for canola oil, avoid the refined version, which has been artificially bleached and deodorized.

The finest coconut oil is cold-pressed and virgin. Your coconut oil should have the scent of a Caribbean beach.

It includes medium-chain fatty acids, which may help you lose weight while also supporting your neurological system.

Looking for the finest frying oil? People often claim that canola oil (which has a smoke point of roughly 400 degrees F) is the best frying oil.

Canola oil is not the healthiest cooking oil available. Instead of canola oil, I prefer coconut oil for frying.

Coconut oil is a suitable mid-temperature frying oil, with about 350 degrees F smoke.

2. Extra Virgin Olive Oil

Olive oil vs. canola oil: which is better? Canola oil and olive oil are often compared.

Olive oil is the clear winner whenever it comes to olive oil vs. canola oil!

Olive oil is one of the healthiest oils available. Olive oil has several health advantages and is a staple of the Mediterranean diet.

Look for a darkly colored glass jar that contains organic extra-virgin or cold-pressed olive oil. Many cheaper GMO vegetable oils are combined with inferior, false olive oils, so check sure it’s GMO-free.

It’s vital to remember that olive oil shouldn’t be heated to high temperatures and that its health advantages are best acquired when it’s utilized raw. Olive oil is fantastic for pouring over finished items like cooked vegetables and homemade salad dressings.

3. Organic, pasture-raised butter or ghee

Canola oil may be replaced with high-quality butter or ghee. In addition, alpha-lipoic acid and conjugated linoleic acid, found in both butter and ghee, may help you lose weight.

They also include beneficial short-chain fatty acids and have a greater heat tolerance. Stick to organic grass-fed butter when purchasing butter.

Also, there’s a distinction to be made between butter and margarine. Margarine typically includes vegetable oils, so stick with butter.

4. Palm Oil (Red)

Red palm oil is derived from the palm fruit rather than the palm kernel, and it’s rich in vitamin E and beta-carotene in its natural condition. It’s also heat resistant and perfect for cooking.

When purchasing palm oil, make sure it is certified sustainable.

If you must purchase canola oil for any reason, make sure it’s organic canola oil since it won’t come from genetically modified plants. Using genetic engineering or modification in certified organic goods is still prohibited.

5. Avocado Oil

Avocado oil is one of my favorite cooking oils because of its high smoke point and mild taste, which works well with almost any recipe.

Avocado oil, like olive oil, is high in monounsaturated fat, which is a healthy dietary fat. It’s so good for you that if you go to France, it’s been given prescription medicine status for its anti-arthritis properties.

Last Thoughts

  • You simply cannot afford to continue consuming canola oil, whether it is genetically modified or not, for the sake of your health.
  • Choosing which oils are the finest to cook with and use at home might be difficult. But one thing is certain: canola oil is not the healthy, safe alternative that the mainstream media would have you think.
  • Canola oil has grown so popular that it may be found in a variety of meals, even those that you would consider “healthy.”
  • Canola oil is really targeted at the health-conscious market rather than the junk food sector.
  • However, to safeguard your health and the health of your loved ones from the hazards of this popular cooking oil, you must be cautious and read labels carefully.
  • Use the information you’ve learned to protect your health! I genuinely hope you avoid canola oil as well as other GMO goods.
  • Look for foods that are labeled as non-GMO. has further information. I also recommend consulting the Non-GMO Shopping Guide.
