Is Rapeseed Oil Healthy? The Truth Exposed

Rapeseed oil is a popular cooking oil that has been used for centuries in many parts of the world. It is made from the seeds of the rapeseed plant, which is a member of the mustard family. Rapeseed oil is known for its high smoke point, making it a great choice for high-heat cooking. It is also a good source of healthy fats, including omega-3 fatty acids. But is rapeseed oil really healthy? In this blog, we will explore the truth about rapeseed oil and its potential health benefits. We will look at the nutritional content of rapeseed oil, its potential health benefits, and any potential risks associated with its use. By the end of this blog, you will have a better understanding of whether or not rapeseed oil is a healthy choice for your cooking needs.

The History of Rapeseed Oil: From Industrial Uses to a Kitchen Cooking Staple

Rapeseed oil, also known as canola oil, has come a long way from its humble beginnings as an industrial lubricant. Today, it is celebrated by health-conscious individuals seeking natural and holistic alternatives in their quest for a balanced lifestyle. In this blog post, we will delve into the intriguing history of rapeseed oil, tracing its origins as an automobile oil to its transformation into a popular choice for mindful eaters. Get ready to discover the shocking truth behind this toxic oil and how it has evolved into the false truth of a healthy cooking oil.

Early Days: Rapeseed Oil as Automobile Lubricant

Rapeseed oil was first cultivated thousands of years ago in Asia and Europe for its numerous uses. However, it wasn’t until the Industrial Revolution that rapeseed oil found its niche as an automobile lubricant due to its high viscosity and resistance to heat. Its ability to withstand extreme conditions made it a valuable asset in machinery during the early 20th century.


The Dangers of Rapeseed Oil

Rapeseed oil has been gaining popularity in recent years as a healthier alternative to other cooking oils. However, it is important to understand the potential dangers of this oil before making it a regular part of your diet. Rapeseed oil is high in omega-6 fatty acids, which can lead to inflammation in the body. This can cause a variety of health issues, including heart disease, diabetes, and even cancer. Additionally, rapeseed oil is often highly processed, which can strip away many of its beneficial nutrients. This means that the oil may not be as healthy as it is purported to be. It is important to be aware of the potential risks associated with rapeseed oil before making it a regular part of your diet.

Toxic Reputation: The Dark Side of Rapeseed Oil

While rapeseed oil had industrial applications, it faced challenges when it came to human consumption. Raw rapeseeds contain high levels of erucic acid, which is toxic when consumed in large quantities. This toxic reputation hindered its use as a food product for many years. However, this all changed in the 1970s with the development of low-erucic acid rapeseed oil (LEAR) which is now commonly known as canola oil.

Despite its industrial success, rapeseed oil’s reputation took a sharp turn in the mid-1900s when concerns about its safety arose. Studies showed that the high levels of erucic acid found in rapeseed oil could be toxic and potentially harmful to human health.

By the mid-1900s rapeseed oil was no longer used in cars due to its toxic reputation and the development of other lubricant alternatives. The focus shifted towards using it as a food product instead. In fact, the name “canola” was created from combining the words “Canadian” and “oil” to rebrand and distance itself from the negative connotations associated with rapeseed oil. This shift in perception led to canola oil becoming a popular cooking oil choice in North America and eventually worldwide.

Health Risks Linked to Rapeseed Oil

Rapeseed oil is high in omega-6 fatty acids, which can lead to inflammation in the body. This can increase the risk of developing chronic diseases such as heart disease, diabetes, and cancer. Additionally, rapeseed oil contains erucic acid, which has been linked to heart damage in some studies. It is important to note that not all rapeseed oil is created equal. Some brands are processed to remove the erucic acid, making them safer to consume. However, the removal of these acids requires extreme processing which can actually make the oil more toxic, due to chemical byproducts used in the processing and undergoing extreme high heat temperatures.

Reinvention: The Birth of Canola Oil

In the 1960s, Canadian researchers embarked on a mission to develop a new variety of rapeseed with lower levels of erucic acid and glucosinolates—the compounds responsible for the bitterness often associated with rapeseeds. Through careful breeding techniques, they successfully created “canola” (a contraction of “Canadian” and “oil”)—a new strain that met stringent safety standards.

The Rise of Canola Oil through Mistaken Benefits

Canola oil quickly gained popularity due to its perceived nutritional benefits. It contains low levels of saturated fat and is rich in monounsaturated fats, omega-3 fatty acids, and vitamin E. These qualities make it a heart-healthy option that can help reduce the risk of cardiovascular diseases when used as part of a balanced diet.

One of the reasons for canola oil’s widespread adoption is its versatility in the kitchen. Its neutral flavor profile and high smoke point make it ideal for various cooking methods, including sautéing, baking, grilling, and frying. Whether you’re whipping up a stir-fry or baking your favorite cookies, canola oil proves to be a reliable companion.

A Shocking Twist: The Processing Dangers of Canola Oil

While canola oil may seem like a healthy choice, some concerns have arisen about its processing methods. The majority of canola oil on the market is heavily refined using chemical solvents that may leave behind traces of hexane—a neurotoxin and air pollutant. Additionally, high-heat refining processes can destroy some of its beneficial nutrients.

While canola oil has been marketed as a healthy alternative, experts caution against its widespread consumption due to the potential risks associated with its processing methods.

Canola Oil: A Healthier Alternative or Just Another Toxic Oil?

While canola oil may have shed its toxic reputation in recent years, it is still crucial to carefully consider the potential health risks associated with its consumption. Several studies have suggested that canola oil might have negative effects on the cardiovascular system, potentially contributing to inflammation and even neurological disorders. Furthermore, the high heat and chemical processing involved in the production of canola oil can lead to the presence of harmful trans fats in the final product, which can have adverse effects on our overall health and well-being. Therefore, it is advisable to be mindful of these factors and make informed choices when it comes to incorporating canola oil in our diets.

Conclusion: Avoid Both Oils for Optimal Health

In conclusion, while rapeseed oil and canola oil may have their own unique histories, they both share similar potential dangers when it comes to our health. Both oils contain high levels of omega-6 fatty acids and undergo extensive processing, which can strip away beneficial nutrients and potentially leave behind harmful byproducts. It is important to be mindful of these risks and consider alternative, healthier options for cooking and consuming oils. Opting for natural, unprocessed oils such as olive oil or coconut oil may be a better choice for optimal health. Let’s continue to educate ourselves and prioritize our well-being by making informed choices when it comes to our diet and nutrition. Stay healthy!

While rapeseed oil may have had a toxic reputation, its successor, canola oil, may not be the “healthy” alternative it is marketed to be. Experts suggest avoiding both of these oils for cooking.

  1. Is canola oil good or bad for you? When it comes to canola oil, some people view it as a healthy food while others avoid it at all costs. When there are two extremely passionate viewpoints, it can be very challenging to get to the bottom of it all.

    On the one hand, detractors claim that canola oil is completely toxic, contains “the infamous chemical warfare agent mustard gas,” and causes conditions from mad cow disease to blindness. On the other hand, supporters believe that canola oil is one of the healthiest oils on the planet and offers canola oil benefits because it’s rich in omega-3s, low in saturated fats and is a good source of oleic acid.

    Granted, these properties are true on a surface level, but there is much more to the canola story.

    Why is canola oil bad? A genetically modified product, canola oil is a Canadian invention that’s backed by Canada’s government, cheap to manufacture, and many packaged or processed foods contain it.

    Canola oil was first created in the early 1970s as a natural oil, but in 1995, Monsanto created a genetically modified version of canola oil. As of 2005, 87 percent of canola grown in the U.S. was genetically modified, and by 2009, 90 percent of the Canadian crop was genetically engineered.

    With so many oils on the market and so much talk about the different types of oil, it’s difficult to sift through what’s fact, what’s entirely fiction and most of all which is the healthiest oil to use. I want to explain all the reasons why canola oil is not what you want to add to your shopping cart from genetic modification to an overload of unhealthy fats — plus, better alternatives and resources to help you avoid GMOs across the board.
    What Is Canola Oil?

    Rapeseed oil is made from the rapeseed plant, specifically from the seeds of the rape or rapeseed plant, which is a member of the mustard (Brassicaceae) family. What is canola then?

    It was in the early 1970s that canola was first bred from rapeseed at the University of Manitoba in Canada by Keith Downey and Baldur R. Stefansson.

    In 1998, “the most disease- and drought-resistant canola variety to date” was developed using genetic modification, and this is how the majority of recent varieties are produced.

    Is canola oil vegetable oil? Yes, it’s a type of vegetable oil so it’s also sometimes referred to as this as well.

    What is canola oil made from? It comes from the canola plant.

    Wild rapeseed oil contains large amounts of erucic acid, which is known to cause health problems, so the canola plant was developed from rapeseed in order to use it to produce a food-grade canola oil with lower erucic acid levels.

    The name of canola oil was originally LEAR (low erucic acid rapeseed) but for marketing purposes was changed to canola oil. This word was derived from the combination of “Canada” and “ola,” meaning oil.

    Canola oil is a much more appealing name than LEAR oil or rape oil, but should you use it in your foods?

    Canola oil price is relatively cheap so it’s not surprising that there are many canola oil uses. The oil works well as an industrial oil and has been used in candles, soaps, lipsticks, lubricants, inks, biofuels and even insecticides.

    Once the powers that be figured out how to genetically modify rapeseed oil, it began being sold as an edible food product.

    Hence, it’s been brought to market with the claim that it’s a wonder oil, low in saturated fats and a source of omega-3 fatty acids. But in its current hybridized and modified state, it can cause a large number of health issues that you will learn about shortly.

    Canola oil was developed as the food industry began to search for healthy and cost-effective alternatives to saturated fats in oils. These saturated fats had come to the mainstream attention as a result of the American Heart Association and other United States government agencies spreading reports of saturated fats, often found in commonly used cooking oils, being bad for your heart health.

    Many of these reports were particularly aimed at corn oil and soybean oil.

    As food manufacturers searched and experimented, they discovered rapeseed oil. Rapeseed oil is monounsaturated oil.

    The problem with this original type of rapeseed oil is that it was very high in erucic acid. Erucic acid is a fatty acid found in rapeseed and mustard oils that’s linked to heart damage, in particular Keshan disease, a disease characterized by fibrotic lesions of the heart.

    Food manufacturers continued their journey into refining rapeseed and canola oils until they came up with a formula in the late 1970s to genetically manipulate the rapeseed plant by seed splitting. This seed split oil produced canola oil with less erucic acid and higher amounts of oleic acid.

    This was the oil referred to at the time as LEAR.

    Although there are not the previously high levels of erucic acid in canola oil, there are still reasons for serious concern if you use canola oil.
    How Is It Made?

    To use the trademarked “canola” name, canola oil ingredients include only one thing, canola oil, but that oil can’t contain more than 30 micromoles of glucosinolates and less than two percent erucic acid.

    What is canola oil made of? It’s made of the oil that comes from crushing the seeds of the canola plant to express the seeds’ oil content.

    Each tiny contains about 42 percent to 43 percent oil. The leftover canola meal is commonly used as animal feed.

    How is canola oil made? It’s one of several vegetable oils that go through the process of being refined, bleached and deodorized.

    A solvent called hexane is used to chemically extract the oil from the seeds.

    Does canola oil go bad? An unopened bottle has a shelf life of about two years before it goes bad.

    Most sources say that an open bottle of oil will become rancid in a year or less.
    Nutrition Facts

    You’re probably wondering about canola oil nutrition.

    Is canola oil good for you? As is true with any food, the key to understanding the health qualities of canola is to look at the entire nutritional profile and not just one or two components.

    One cup of canola oil contains about:

    1,927 calories
    218 grams fat
    16.1 grams saturated fat
    0.9 gram trans fat, yet other reports claim that it is much more
    155 micrograms vitamin K (194 percent DV)
    38.1 milligrams vitamin E (190 percent DV)

    As you can see canola oil calories are not low. A study published in the Journal of the American Dietetic Association reports that a majority of canola oil used in processed food has been hardened through the hydrogenation process, which introduces levels of trans fatty acids into the final product as high as 40 percent.

    Taking a closer look at canola oil nutrition facts, its full fatty acid profile looks something like this:

    Saturated fat: 16.1 grams
    Monosaturated fat: 138 grams
    Polysaturated fat: 61.4 grams
    Omega-3 fatty acids: 5,018 or 19,921 milligrams depending on the source
    Omega-6 fatty acids: 40,646 milligrams

    Is canola oil bad? One of the things I noticed while doing research is that most canola oil had a poor omega-3/6 ratio of 8:1 and loads of trans fats, with only one source showing it was closer to 2:1 (the first number being omega-6s and the second the omega-3s).

    Many people tend to get too many omega 6s in their diet and not enough omega 3s. A high consumption of vegetable oils like canola can be one of the reasons for this.

    Why Is Canola Oil Bad for You? Any Potential Benefits?

    Originally, rapeseed oil may not have had so many negative health effects.

    Why is canola oil so bad for you? For three main reasons, most canola oil today can be very harmful to your body:

    Over 90 percent of canola oil is genetically modified.
    Canola oil is a refined oil that’s often partially hydrogenated to increase its stability, but this increases its negative health effects.
    It’s been linked to increased inflammation in animal studies, and chronic inflammation is believed to be at the root of most diseases.

    It’s for these two reasons that I recommend you switch to healthier oil alternatives that I list below.

    What can it do to you? There have been no long-term, viable studies done on GMO canola oil, but there are reports that it has caused many kidney, liver and neurological health issues.

    This makes sense since there are other reports that GMO products like corn and soy also can cause negative health effects. So if you’re comparing soy or corn oil vs canola oil, I would say avoid them all!

    Is vegetable oil bad for you? According to the Weston A. Price Foundation and fat experts Sally Fallon and Mary Enig:

    Like all modern vegetable oils, canola oil goes through the process of refining, bleaching and degumming — all of which involve high temperatures or chemicals of questionable safety. And because canola oil is high in omega-3 fatty acids, which easily become rancid and foul-smelling when subjected to oxygen and high temperatures, it must be deodorized. The standard deodorization process removes a large portion of the omega-3 fatty acids by turning them into trans fatty acids. Although the Canadian government lists the trans content of canola at a minimal 0.2 percent, research at the University of Florida at Gainesville, found trans levels as high as 4.6 percent in commercial liquid oil. The consumer has no clue about the presence of trans fatty acids in canola oil because they are not listed on the label.

    Monsanto has been incorporating genetically modified organisms in its canola oil seeds, and now we know that Monsanto has also been selling GMO seeds for the following plants:

    Sugar beets

    In 2016, some progress was made when it comes to food containing genetically modified ingredients. A bill was signed by the president amending the Agricultural Marketing Act of 1946.

    So now companies are required by law to disclose the presence of GMO ingredients through text labels, symbols or digital links (like scannable QR codes).

    Sounds great, but the problem is that it’s left up to the secretary of agriculture to decide what amounts of GMO ingredients need to be present in a food product in order for the GMO labeling law to be a requirement.
    Top 6 Dangers
    1. Kidney and Liver Problems

    The majority of canola oil produced today is genetically modified. The side effects of GMOs in general cannot be overstated.

    In a 2011 review published in Environmental Sciences Europe, 19 studies of mammals fed GMO soybeans and corn were evaluated. The 90-day trials indicated liver and kidney problems as a result of GMO foods.

    The kidney and liver findings actually were differentiated by sex with the kidneys being disrupted by 43.5 percent in male mammals and the liver being disrupted in female mammals by 30.8 percent.

    The kidneys and the liver are absolutely vital to our existence so ingesting a genetically modified food like canola oil is really not something to take lightly.
    2. Life-Threatening Heart Trouble

    As a monounsaturated oil, rapeseed oil has high levels of erucic acid. Erucic acid is a fatty acid that’s associated with heart damage, specifically Keshan disease, a disease that manifests itself with fibrotic lesions of the heart.

    Research has shown that in areas where people are prone to Keshan, not only are selenium levels lower, but eurucic acid levels are higher.

    Partially hydrogenated vegetable oils like canola are also known for causing inflammation and calcification of arteries, which are well-established risk factors for coronary heart disease.
    3. Hypertension and Strokes

    Previous studies have shown that the consumption of rapeseed oil and some other types of vegetable oils shortens the life span of stroke-prone and hypertensive animal subjects. Specifically, research carried out at the Nutrition and Toxicology Research Divisions of Ottawa discovered that rats bred to have high blood pressure and proneness to stroke died sooner when fed canola oil as the sole source of fat.

    Additionally, the rats fed the non-canola oil-based diets lived longer than the rats fed canola oil.

    Another study published in 2000 in Toxicology Letters specifically looked at the effects of canola oil on blood coagulation time or how long it takes blood to clot in stroke-prone animal subjects. The study found that there was a “canola oil-induced shortening of blood coagulation time and increased fragility in [red blood cell membranes],” which may promote the occurrence of strokes in animal subjects that are stroke-prone.

    4. May Retard Normal Growth

    Up until recently, it was not legal to use canola oil in infant formulate. There have been what I think are valid concerns about canola oil retarding growth in children.

    Specifically, the euroric acid in canola oil is harmful to infants due to an inability to properly break it down. The FDA previously made the use of canola oil illegal in baby formula.

    However, as of a few years ago, canola oil made it to the generally recognized as safe list.

    Not only is it highly concerning to feed developing infants a GMO oil, but it’s also highly questionable to give them unhealthy fats. Proponents brag about canola’s overall healthy fat profile, but I don’t buy it.

    Now it’s being sold in the form of a baby’s first meal. Of course, I highly encourage skipping commercial formulas and opting for breastfeeding if you can.
    5. Increases Intake of Unhealthy Trans Fats

    According to a study published in the Journal of Food Lipids, when soybean and canola oils purchased in the U.S. were evaluated, “The trans contents were between 0.56% and 4.2% of the total fatty acids.”

    When canola oil undergoes hydrogenation, which it often does to become a partially hydrogenated oil, this increases its level of trans fats. These are a group of fats you want to avoid as much as possible since they’re scientifically known to increase LDL cholesterol and lower HDL cholesterol.

    Research has also related trans fats to weight gain. In an animal study, trans fats lead to weight gain even when compared to the same caloric intake.

    Keeping this in mind with the obesity epidemic we’re facing, it’s a sign to reconsider these oils in an effort to help restore healthy weight and metabolic functioning, although — of course — only part of the problem of the growing problem.

    When you read “partially hydrogenated oil” on any food label, that guarantees there is some amount of trans fat present. This is true even when the label tells you that there is zero trans fat.

    How can that be? Well, if a serving contains less than 0.5 grams, the company is allowed to indicate there are no trans fats. Frustrating, I know.

    Trans fatty acids are hazardous byproducts of food processing and are truly health destroyers. In fact, if you decide to get rid of your canola oil, I would also stop cooking with these oils as well: corn oil, safflower oil, soy oil and vegetable oil.
    6. Numerous Potential GMO Health Side Effects

    I already mentioned the link between GMOs and negative liver and kidney implications, but it doesn’t stop there. According to the Center for Food Safety site, there are several new and very serious health concerns and unexpected effects of genetic engineering unearthed by scientific research:

    Allergic reactions
    Loss of nutrition


    There are much healthier choices than “vegetable” oils, which sound healthy but are far from it. Most vegetable oils (canola, corn, peanut, safflower, etc.) are sourced from GMO crops and/or are highly refined.

    So, what are the best oils for cooking? Here are the top oils I personally use as a substitute for canola oil:
    1. Coconut Oil

    Is coconut oil bad for you? The refined variety is chemically bleached and deodorized and is not the type you want if you’re looking for a healthier alternative to canola oil.

    Coconut oil is best when it’s cold-pressed and virgin. Your coconut oil should smell like you’re on a beach in the Caribbean.

    It contains medium-chain fatty acids that can support both fat loss and your nervous system.

    Looking for the best oil for frying? People often say that the best frying oil is a vegetable oil like canola (canola oil smoke point is about 400 degrees F).

    Canola is certainly not the healthiest oil for frying. Rather than using canola oil for frying, I recommend coconut oil.

    With a smoke point of about 350 degrees F, coconut oil is a good mid-temperature frying oil.
    2. Olive Oil

    Which is better olive oil or canola oil? People often compare canola oil vs. olive oil.

    If there’s a contest between olive oil vs. canola oil, olive oil wins every day of the week!

    Olive oil has been shown to be one of the top healthy oils. Olive oil benefits are tremendous and at the heart of the Mediterranean diet.

    Look for an organic extra-virgin or cold-pressed olive oil that’s available in a darkly colored glass container. Many inferior, fake olive oils are mixed with cheaper, GMO vegetables oils so make sure it’s GMO-free.

    It’s important to know that olive oil shouldn’t be cooked at high heat and its health benefits are best obtained when you used it uncooked. Olive oil is great in homemade salad dressings and for drizzling on finished products like cooked vegetables.
    3. Ghee or Organic, Pasture-Raised Butter

    High-quality butter or ghee both make a great canola oil substitute. Both butter and ghee benefits come from alpha lipoic acid and conjugated linoleic acid, which can promote weight loss.

    Also, they contain healthy short chain fatty acids and have a higher heat threshold. When buying butter, stick with organic grass-fed varieties.

    Remember, too, there’s a difference between butter and margarine. Stick with butter, as margarine often contains vegetable oils.
    4. Red Palm Oil

    Red palm oil is made from the palm fruit instead of the palm kernel, and in its unrefined state, it’s high in vitamin E and beta-carotene. It’s also stable under high heat and great for cooking.

    Make sure when buying palm oil that it’s certified sustainable.

    If for some reason you must buy canola oil, make sure that it’s organic canola oil because then it at least can’t be from genetically modified plants. It’s still illegal to use genetic engineering or modification in certified organic products.
    5. Avocado Oil

    Avocado oil is one of my favorite cooking oils, as it has a high smoke point and mild flavor that goes with any dish you could imagine.

    Avocado oil, along with olive oil, is a good source of monounsaturated fat, a beneficial dietary fat. It’s so healthy, in fact, if you visit France, it’s actually received prescription drug status there for its effects against arthritis.
    Final Thoughts

    Whether the canola oil you’ve been using is genetically modified or not, you really can’t afford to keep using it for the sake of your health.
    It can be confusing to know which are the best oils to choose to cook with and use at home. But one thing you can bet on is that canola oil is simply not the safe, healthy alternative that the mainstream media would have you believe.
    Canola oil has become so popular it’s found in many foods, including ones you may think are “healthy” food choices.
    In fact, canola oil is marketed to the health-conscious industry rather than the junk food industry.
    However, you must beware and read labels diligently in order to protect your health and the health of your loved ones from the dangers of this popular cooking oil.
    Now that you’re armed with the facts, use them to guard your health! I truly hope you will steer clear of canola oil and all GMO foods.
    Look for foods with the non-GMO label. Find more info here: I also suggest checking out the Non-GMO Shopping Guide.

  2. I am so ill from rape seed oil! It took me around 3 years of not being able to eat out & finding what was the cause of the pain is worst than laber & not being able to leave a toilet & also needing a bowl on your lap, it stopped me from being able to have a normal life, I was under a dietitian with the hospital & also had unpleasant test done, it’s now in most items of food & it’s very difficult to find food which haven’t got it in, what is so annoying is that it isn’t put down as a alegen! I find that organic items are the best in the way of mayonnaise & salad cream also only use real butter!! It’s in bread, crisp & soups, biscuits mostly everything these days. It was so difficult for me to find out what was making me so ill it’s worst than just having a food intolerances! I know because l also have IBS. I want people to be aware of this because it took away from me being able to go out or traveling far. Thankfully l am more careful now on what I buy & eat. I still find l have to ring firms when I am ill because it’s not always put down on the ingredients list! People are being ill & not realising why!

  3. I m using this oil but feeling constant pain in right ankle. Is it bad for joints. Kindly clarify I think rapeseed oil good at kitchen. Some people point out in their experience ankle pain. This is second bottle we are using. My pain in ankle is not going away. Rest of family does not have any issue. I m 53 years.

    1. You should stop using Canola Oil because Canola oil is VERY TOXIC and UNHEALTHY FOR YOU!! You can find pesticides that contain 96% Canola Oil…they use it to kill bugs with. STOP USING IT NOW!!!

  4. When I get to the part where you make arbitrary statements such as:
    “The fat found in butter . . . is definitely unhealthy. . .”
    “Some of the good effects of good fats include:”
    it becomes apparent that your article is basically a propagandistic and biased piece of marketing material and I immediately move on. Only people who wish to manipulate the thoughts of others use terms like “good fat” and “bad fat”. You don’t even differentiate between regular rapeseed and the hybridized rapeseed that is supposed to be used for canola oil in the U.S. Even though it was hybridized, it didn’t eliminate the toxin erucic acid. I diminished it, but there you are with that toxin still in your oil believing that “a little bit of bad stuff doesn’t hurt anyone” . Add up all the “little bits of bad stuff” in American food v.s. what is allowed in Europe, etc. and you can easily extrapolate the horrendous impact that it has on health in America.

    1. Yes I stopped reading once I got to butter is definitely unhealthy. No scientific based evidence suggests butter is bad for. In fact butter and lard will improve your health.

      1. Butter is very bad for you it is dairy so of course it has high amounts of cholesterol and saturated fat which has a direct link to heart disease,cardiovascular disease,type 2 diabetes and breast cancer any type of dairy is initially unhealthy just do some research and get your calcium and nutrients elsewhere easily

    2. I just read an article that said the RAPESEED Plant was genetically altered, meaning genetically modified which means GMO, it was not hybridized. They try to say that because it is being grown by organic standards, that it is organic but it is FAR from it. It is a toxic oil and will always be a toxic oil. You can go to Home Depot and go to the Pesticide aisle and find Pesticides that contain 96% Canola Oil!!!! If you eat Organic foods, you must still read the labels. I have been eating Dave’s Killer Organic Bread – 21 Whole Grains and Seeds and thank G-d I read the label EACH AND EVERY TIME because just recently they changed the recipe for the 21 Whole Grains and Seeds bread and are now using Canola Oil. No announcement to the consumer….nothing because they just changed it and hoped people would not notice….but I did!!! People could die from this change yet they do not care what so ever. Dave, the original owner and maker of this bread ONLY used organic ingredients, but, he sold the company a few years back and now Dave’s Bread is toxic and contains toxic ingredients. Whole Foods did the same thing – they changed the recipe for their Organic Bird Eye Bread, which did not contain Soy oil or Canola Oil and without letting the consumer know they change the recipe and the packaging which then caused me to read the label and found the toxic ingredient Canola Oil. Take care of yourself and remember to ALWAYS READ FOOD LABELS!!! Thanks for being one of those that are in the KNOW!!! Blessings!!

  5. As someone who is highly allergic to rapeseed oil your comments re allegies is not true. It makes me so ill – vomiting, stomach pains worse than labour pains, wind, fainting, disorientation and the list goes on. I now have trouble buying any process foods as everyone is using it. Disgusting stuff. I cant go out for meals as used as cheap alternative to better standard oils. It also causes bad hayfever and asthma for many people while growing.

    1. I totally agree that this oil is not what it is made out to be. I found this to be the case over 30 years ago . For me it affects my joints , particularly my ankles and fingers which are painfull in the morning if I unknowingly consume the stuff in mayonnaise or spreadable butters . Trouble is it’s in everything these days even bread . I suspect all the food manufacturers are using the stuff because it’s the cheapest

  6. Why persist in perpetuating the myth that saturated fats elevate blood cholesterol, when there is absolutely no scientific evidence of this? This nonsense dates back to the now wholly discredited work of Ancel Keys in the late 1950’s. Take a look at the Framingham studies which have been running since 1948 and have singularly failed to demonstrate any link between saturated fat and elevated cholesterol.

    The link between elevated cholesterol and heart disease is also misleading. Total cholesterol is much less important than the ratios of HDL and LDL. Raised total cholesterol carries a small increase in risk of heart disease, but decreased levels of risk of stroke, liver disease, renal disease and cancer.

    Vegetable fats derived from seeds (flax, cottonseed, sunflower etc.) have high omega 6 fatty acid contents, and this IS associated much more closely with a range of inflammatory disease, including heart disease and cancer. Vegetable oils derived from fruits or nuts (olive oil, coconut oil, macadamia oil etc) have lower levels of harmful omega 6 fatty acids, but you should be aware that we are not evolved to handle large quantities of polyunsaturated fatty acids in vegetable oils and should stick to animal fats where possible.

    Rapeseed or Canola oils have the best ratio of omega 3 (beneficial) fatty acids to omega 6 (inflammation promoting) fatty acids of commonly available vegetable oils, but hard, saturated animal fats (butter, lard, tallow) are far healthier. Rapeseed oil is a useful adjunct to butter for frying as it raises the smoke point and prevents the butter from burning.

    1. 80-90 percent of the rapeseed/canola sold in the U.S. is GMO. It has been banned by the EU so it’s not in the UK.

    2. YES!!! The Rapeseed plant is toxic to humans and bugs will not eat it. It is highly processed, Hexane is used to remove the hull from the seeds. It is processed at extremely high temperatures and it stinks so bad that they add a deodorant to it to cover the stench. They claim that Canola Oil is organic, yet, they may be growing it by organic standards, yet, because it has been genetically altered/genetically modified that means that it is GMO!!! The best thing to do is to use Organic Olive Oil, but, make sure it is 100% Pure Organic Olive Oil. The FDA allows manufactures to still call it Olive Oil if it is 65% Olive Oil. The other 35% of the oil can be Canola Oil, Corn Oil, Sunflower Oil, etc. COSTCO sells an EXCELLENT Organic Olive Oil which is not expensive at all. Please change your cooking oils if you value your health!!!! Blessings!

  7. Be sure to get the non-gmo coldpressed canola oil to avoid any risk of problems that some people warn about :)

  8. From every other article I just read rapeseed is VERY bad for you. Canola oil is made from genetically modified rapeseed and is supposed to be good for you tho one article says different. Also read that the FDA was paid 50 million to approve it. Very confusing and also scary. I’m throwing out my canola oil and sticking with olive oil

    1. Not in the UK!! We don’t have gmo junk here. Our rapeseed is pure and cold pressed. I do feel sorry for you across the pond with your Frankenstein food.

      1. If you are eating Canola Oil it is not a healthy oil to be eating. Please do your research on the Rapeseed plant. It is VERY toxic to humans and bugs will NOT go near it!!!! Please reconsider what you are putting into your body – it is a CHEAP oil and they use HEXANE to remove the hull from the seed. Blessings!!

    2. It was a deal between the U.S. government and the Canadian government. Canada had huge surpluses of canola oil. They used it as an industrial lubricant. A deal was made, and Americans are now eating it. The name “Canola” is a mash-up of Canada Oil.

  9. What an excellent review/explanation of Rapseed oil. Not too long and not too short. Straight to the point and information required for this amazing oil. Thank you
    Keep up the good work
