THIS is what Canola Oil does to Your Body (the EVIDENCE no one shows!!!)

What effect does Canola Oil have on your health? There are many ideas online but what does science show about canola oil & health? Canola oil, sometimes called rapeseed oil, is mainly monounsaturated. Is it healthy or toxic? What does the science say about canola oil?
We look at cholesterol, glucose, insulin, inflammation, oxidation, body weight, cancer & risk of mortality. Canola & lipids. Canola compared to olive oil, sunflower seed oil and foods higher in saturated fat like butter.
LDL-Cholesterol was a bit lower on canola than olive oil but ApoB didn´t significantly differ.
canola vs sunflower oil: LDL-Cholesterol lower on canola, but not ApoB
canola vs saturated fat: LDL-Cholesterol, ApoB and triglycerides all lower on canola
VLDL-cholesterol, ApoA1, lp(a), HDLc not significant
Bottomline: canola oil better for lipids than saturated fat, no clear superiority compared to other vegetable oils
refined canola also retains lipid-lowering effect

[@pranjal86able]

Here are the key takeaways: Glucose Metabolism: Canola oil doesn't seem to have a negative impact on glucose metabolism. Studies have shown no significant effect on fasting glucose, and some even found improvements in fasting insulin and insulin resistance. Cooking with Canola Oil: Trials have shown that cooking with canola oil doesn't seem to affect glucose metabolism negatively. Even refined canola oil used in substantial amounts didn't show harmful effects. Body Weight: Evidence indicates that canola oil does not induce weight gain. Some studies even reported a reduction in body weight, particularly in participants with type 2 diabetes or when compared to saturated fat-rich foods. However, the effect was small and not entirely convincing. Fatty Liver Disease: In a trial with participants having non-alcoholic fatty liver disease (NAFLD), both olive oil and canola oil improved fatty liver, with over 76% of participants on canola oil reverting to normal liver grading. Inflammation: The video found no compelling evidence showing that canola oil causes inflammation in living humans. Some in vitro assays suggested an increase in oxidation products, but in vivo studies did not support this. Oxidation: Canola oil doesn't seem to cause oxidation in vivo. However, it's advised to avoid very high temperatures like deep frying and to favor sautéing instead. Cancer Risk: Large prospective studies report that people cooking with canola have a lower risk of dying of cancer than those cooking with butter, and not higher than people cooking with olive oil. Comparison to Nuts and Seeds: There's limited data comparing canola oil to unprocessed sources of fat like nuts and seeds. One trial found no significant difference between nuts and a canola oil-enriched cereal in various health metrics. Large Trials: Some famous trials like Lyon and Finger used canola oil as part of their intervention and found benefits like lower risk of cardiovascular outcomes and improvement in cognitive function. Personal Preference: The video emphasizes that personal choice matters. Some may prefer cold-pressed canola oil, while others may choose not to consume it at all. The video encourages asking for evidence from those claiming canola oil is toxic. Funding and Bias: The video also touches on funding sources for the studies, mentioning that out of about two dozen references, five studies had some ties to the industry, but excluding them wouldn't fundamentally change the picture. Conclusion: Most of the evidence seems to point to the safety of canola oil and even some benefits. There are areas of uncertainty, and more specific questions may require further research. The video emphasizes that personal choice and preference are valid and that scientific evidence should guide decisions. The video provides a comprehensive and balanced view of the subject, considering various aspects of canola oil's impact on health, cooking practices, and personal preferences.

I have worked in many restaurants that use deep fryers. They would not change the oil which was heated for 10-12 hours a day, just replenishing use oil absorbed by the food. Only occasionally, the deep fryers would be cleaned out and all the oil replaced. - I don't believe any of the trials you have mentioned in and other videos looked at an oil heated for so long a period of time. I believe the longest heating time mentioned was 18 hours, but I could be wrong. A study looking at 80-120 hours of heated oils would be interesting to see.

[@Klaudiuszeg]

To be fair with you, if you do the same with lard or butter, that thing would turn black after so many hours

[@PhilLesh69]

I took a job at a Wendy's while in between jobs for about three weeks. The manager replaced the oil every thursday. By Friday afternoon the oil was already black. They were open 6a.m. to midnight. When I worked a shift I was dropping five pounds of fries into the oil every four ninutes, and the same oil was used for chicken nuggets and chicken patties. They do use canola, though. Because it's healthier. Where I work now we have a deep fryer that they might use three or four times a week for an hour or two at a time, and they replace the oil every week, or sometimes they will replace the oil specifically for something they want to cook in fresh oil, like for a big catering event or somethng.

[@RockMusicTracks]

You can't expect trials to cover every possible scenario and the one you mention is extreme. Most studies would look at the average person's eating habits and that doesn't include eating daily at a restaurant.

[@MB19ap]

​@RockMusicTracks it's sad, but a lot of families do eat out every day, at least around me, and maybe even more than one meal out. For instance they rush out the door grab breakfast through the drive through, they didn't pack their lunch so they stop to grab something somewhere maybe a light, quick lunch or they go somewhere with coworkers, then they pick the kids up from school and they have to get the kids to practice so they stop off at the drive through and get dinner for the family. It is a really sad reality of modern life.

[@MrRADicalOfficial]

That increases the levels of toxic aldehydes and acrylamides, so it's really a shame they can get away with that. This is why I don't eat fast food anymore, or even really restaurant food. A lot of restaurants don't properly clean the dishes, use oils over and over, have microplastic and PFAS contamination, have high sodium and sugar, don't wash their hands or replace gloves, use spices which I'm sure many have pesticides and heavy metals since spices are poorly regulated, use additives for different food products (especially deserts). All signs point towards boycotting fast food and restaurants until the standards are raised A LOT higher. They're filthy.

[@Ivan_Mohnke]

The thing is canola oil is the main fat used in many highly processed foods because it is much cheaper than good quality butter and olive oil. Such products are definitely linked to higher mortality. This could be a confounder for the link between canola oil and mortality but hey, i do not necessarily need to use canola oil so I won’t add it in until there is actual conclusive evidence for it.

[@Kingofwebsites]

Here's my summary of this video with timestamps: 00:00 This video will examine the health effects of consuming canola oil by looking at a wide range of scientific evidence. 00:53 This channel is independent with no sponsorship from any canola or seed oil entities. 01:19 Canola oil slightly lowered LDL-cholesterol compared to olive oil, but both had similar cardiovascular risk metrics. 02:15 Compared to sunflower seed oil and saturated fats, canola oil had lower LDL-cholesterol and ApoB levels. 03:13 No clear superiority of canola oil was observed when compared to other unsaturated vegetable oils. 03:38 Most trials don't specify if they used cold pressed or refined canola oil. 04:06 Refined canola oil retained lipid-lowering properties. 04:34 Some trials tested canola oil's effect when heated, showing reduced LDL cholesterol and ApoB levels. 06:13 Long-term observational studies suggested those cooking with canola oil had a lower risk of cardiovascular death compared to butter users. 07:11 Canola oil showed no significant effect on glucose metabolism metrics when compared to other oils and fats. 08:07 Caloric intake and weight loss can impact glucose metabolism more than the type of fat consumed. 09:04 Refined canola oil did not negatively affect glucose metabolism, even in large amounts. 10:43 Long-term observational studies suggested no increased risk of type 2 diabetes from cooking with canola oil. 11:10 Current evidence suggests canola oil is not problematic for glucose metabolism, but more long-term studies are needed. 11:40 The video references around two dozen scientific studies; five of which have some connection to the canola or vegetable oil industry. 12:35 Funding source shouldn't discredit scientific studies; it's essential to evaluate all evidence based on scientific merit. 13:03 A meta-analysis of 23 studies found canola oil reduced body weight slightly, especially when compared to saturated fat-rich foods. However, most individual trials did not show significant differences. 14:23 Despite some studies showing a reduction in body weight with canola oil consumption, there were no significant differences in BMI, waist circumference, or body fat. 14:48 Canola oil doesn't seem particularly fattening when compared with other oils in terms of satiety. 15:33 There's no significant change in body weight when cooking with canola oil, as observed in certain trials. 17:06 The discussion is about pure canola oil, not processed foods that contain canola oil as one of many ingredients. 18:02 Regarding inflammation, a meta-analysis found no significant difference in inflammation markers when comparing canola oil to other oils like olive or sunflower seed oil. 19:22 Many are concerned about linoleic acid in seed oils leading to inflammation, but long-term data indicates people consuming more linoleic acid tend to have lower inflammation markers. 20:45 Studies investigating oxidation markers in individuals consuming canola oil found no significant differences, even when canola oil is used for cooking. 21:13 HNE, a product of lipid oxidation, was undetectable in unheated canola and remained low even after prolonged heat exposure. 22:03 Canola oil's Vitamin E content, which can inhibit oxidation, is relatively high. 23:26 - In vitro test results sometimes differ from in vivo ones; the t-bars assay for oxidation in canola oil has been criticized for lack of specificity. 24:16 - No compelling evidence showing oxidation from canola oil in humans, but advisable to avoid high-temperature cooking like deep frying. 24:45 - The smoke point of canola oil is around 200°C, and it's better to stay below that temperature. 25:40 - Oxidation alone doesn't mean toxicity, and it's crucial to consider the net effect in humans. 26:09 - Large studies suggest people cooking with canola oil have a lower risk of cancer than those using butter and similar risk as those using olive oil. 27:04 - Comparing oil to whole food sources of fat, there's little difference in health metrics when using canola oil. 27:54 - Trials like Lyon and FINGER used canola oil as part of a Mediterranean diet and saw positive health outcomes, though they made multiple changes. 28:24 - Most evidence indicates the safety and potential benefits of canola oil, but there's still a need for more specific research. 29:17 - Personal preference is essential; canola oil isn't a dietary necessity, and individuals should make their choices. 29:48 - Challenge claims about canola oil's toxicity by asking for evidence from human trials or cohort studies.

[@geriscape]

As someone who is trained in the scientific method (social sciences), I've very much appreciated your presentational mix of approachable engagement with intellectual rigor, all wrapped up with an impressive syncretic ability. As for the particulars of this video, the risk/benefit profile of canola oil, it's reassuring to hear that my use of canola is, well, benign. If there's a specific set of videos on this channel that are my favorites, it's those explaining, via exposition and visual means, and in conversation (with Tom Dayspriing, for example) the function and importance of ApoB in determining atherosclerosis risk (and what can be done to reduce it). No personal physician nor cardiologist had ever discussed the role of ApoB with me. (I had a quintuple bypass 22 years ago). As a 70 year old who admittedly hasn't culled all the comments, I do have a question/request: Is there a point where you might cover the extant and ongoing randomized controlled trials around senolytics? I believe it might well be of interest to a subset of your viewers, beyond my personal and emerging interest in the topic. Thanks.

Thanks for making these videos. I've been happily using Canola oil for years and then suddenly started hearing about how "toxic" canola oil and other seed oils are.

This video is a good reminder to always ask/look for evidence, especially for such extreme assertions 🙂

[@Struwwel2]

All this is good to know. I bought into the narrative about seed oils and canola oil being inflammatory and unhealthy. I guess I'll go back to using canola. I like olive oil, but it's expensive to rely on for cooking. My subjective impression is olive oil tastes better than canola. Other than that, there's no obvious advantage one to the other.

[@markallen381]

Indeed, the price on CO is worth considering.

[@frstnmlstnm8484]

True, I suppose the only reason to buy olive oil is if one is making a dish where the olive oil flavor is important and one could also purchase one of the cheaper olive oils, sometimes good enough is good enough.

Would it be possible for you to address possible health risks of canola and seed oils other than cardiovascular and inflammation?

I'm wondering if the way they are processed (deodorizers and other chemical processes) renders them a health risk.

If you look into them a bit, you will find they are trying to sell you supplements most of the time. You are deficient in X so you should buy Y, disguised into educational videos. Then again their general message is good, improving your own health.

[@ReflectedMiles]

Or they cherry-pick one or two studies that appear to favor this or that point and ignore everything contrary to their assertions. Unless people know how to appraise the credibility of any source of information in advance, the Internet and social media, especially, can act as one huge lying and deceiving machine. It's sad, and I suspect future generations are going to have to deal with that aspect in some way both for health and safety reasons and due to the polarization in society and even professional fields that results from misinformation / disinformation.

[@DavidJohnson-yg8qm]

Good clear information on oil uses, the why's and wherefores. Impressive.

[@DoubleDogDare54]

I wanted to watch your take on canola oil because I recently read Chris Knobbe's take on all seed oils - canola, vegetable, corn, sunflower, all of them - and he is absolutely against them. Especially when combines with sugar, white flour and processed foods. Us poor consumers get caught in the middle with one saying something is healthy, the other that the whatever is toxic. You'd think by now it would be sorted out.

[@HobzyMcRuse]

Most processed foods contain vegetable oils because they have been hydrogenated, giving them a long shelf life and they are very cheap. Sugar and refined flour is just bad because it spikes blood sugar very rapidly and too much over time contributes to metabolic issues like type 2 diabetes. Simple sugars (junk foods) also raise triglycerides and contribute to heart disease (there are many other factors) Canola oil is probably ok with a healthy diet, high in vegetables, lean meats and fruit etc, but Olive oil (to me) tastes much better and is natural, cold pressed and contains some amazing nutrients and anti-oxidants. As Gil said, Vegetable (Seed) oils may be harmful when constantly re-used in fast-food restaurants. All oils should only be used once as they will oxidise and go bad if repeatedly cooked with. Even Butter is healthy in moderation in a diet low in processed junk food. Don't blame the spread for what the bread did :)

[@k.h.6991]

Well yeah, combined with unhealthy stuff like sugar and white flour - in other words: in processed foods, canola oil is unhealthy.

[@RickyVis]

Chris Knobbe's work mostly relates to huge excesses in omega 6 fatty acids. Canola oil is very unique among seed oils because it has a omega 6 to 3 ratio of 2:1 which is a near ideal ratio. Compare that to sunflower oil 40:1 it becomes clear that Canola is the superior option.

Amazingly thorough video with interesting results

[@drott150]

Yet another magnificent long form video chock full of data, insights and revelations which are extremely useful to all of us. THANK YOU! My basic takeaway after the first viewing is that canola is basically comparable or even slightly better than olive oil in most measured parameters. This is somewhat surprising based on all the seed oil hype. I spend a lot of money on high quality olive oil, and these results have me doubting the value of that consumer choice. Based on what I see here, it appears as if the cheap refined canola oil is at least the equal of the finest olive oil with the exception of flavor. That is a surprising revelation indeed. Yet scientific rigor often brings these surprising insights, and I say bravo to that!

[@maylien]

Thank you So much ! I am a believer in the scientific process but many want to just ignore facts. We have used Canola oil for the past few decades along with olive oils so I’m glad to see this presented.

[@stevel5437]

Great review, thank you.

[@iotanb1772]

[@markallen381]

I have learned to maintain my cooking temperatures to stay under the smoke temperatures. I never bring the the oven temperatures over 345 degrees. That has meant I generally have longer cook times in the oven. Nice video!

[@veganne6909]

Another excellent and informative video. Personally I prefer the whole food approach as oils are so calorie dense. If I want olive oil I eat olives, if I want canola oil, I eat canolis 😆

[@jrmint2]

awesome, but one issue is that most Canola oils are made w pesticide laden Monsanto GMO Canola plants. Ive found organic canola oil at Whole Foods and that is what I'm using now. Also, the heating of the oil is indeed toxic to my body...so I only use small amounts and cook at lower temps (to reduce AGEs from both the oil and the meat) if I am stir frying and I do not eat fried foods if at all possible, but that's hard lol. Thanks for this update.

[@TangoMasterclassCom]

At 19:23 you talk about the term "wash-in" diet. This can be used, to see a difference in case a certain food is usually already in the diet. I would love to hear your analysis about eggs, because I understood there is this effect, that if someone is eating zero eggs, adding x amount of eggs per week has a big effect on cholesterol level, whereas if someone is already eating several eggs a week, adding x amount of eggs has now effect on cholesterol (a plateau). I saw some medical doctors show graphs of this. I would also like to know, why people who have familiar hypercholesteremia are recommended not to eat eggs (at least that is what I heard from people with this disease, whose doctors recommended them to avoid eggs). If eggs do not raise cholesterol levels, why then are people with this disease recommended not to eat them? Thank you so much for your work.

[@someguy4967]

he did a video with a world renowned lipidologist and they had a very interesting and informative talk. if you haven't seen it, i believe they address alot of these things and more

[@TangoMasterclassCom]

Yes, I watched that video twice and I still did not understand it. If find that lipidologist so hard to understand (articulation/pronounciation). I am not a native English speaker, maybe that is why. @@someguy4967

Here's a video Gil did about eggs and cholesterol - and he does talk about the plateau effect in it: kzbin.info/www/bejne/fWKxi4GBo553fZo.

[@AndrewPawley11]

Excellent.

[@xcast1]

Great walkthrough! I wonder why it was not mentioned, that Canola is major provider for essential ALA n-3 for the general population (who is not into flax and chia seeds) to meet the RDA. And that may likely be a big factor in a dramatic result study like the Lyon one - which took place before the time when Canola was widespread after invention, and when ALA RDA was rarely met. There is another striking study PMID 17955332 ("Rapid declines in coronary heart disease mortality in Eastern Europe are associated with increased consumption of oils rich in alpha-linolenic acid"), just 'quasi-randomized' by timing, but very specific compared to Lyon and FINGER. The decline is about factor 2 and can be drilled down quite well to the increase in ALA (mainly Canola introduction) at different times for different countries.

[@OneDougUnderPar]

I would like to see a video discussing "adjusting for confounders", it is often used as a hand wave, and while I'm not saying it's being abused, especially in these cases, it does seems like the best area to smudge things in a favourable direction.

[@pookiecatblue]

Yes. I would like to see this, too.

[@phantomcyrano]

Seems like that's intentional. I've started reading several the studies that he's citing and in addition to not having a lot of control in the methods, some of the meta analysis studies seem to reference other studies, the majority of which don't include a feeding trial. So we're expected to take their word on the safety of an industrial food product based on studies where it wasn't even fed to people in a controlled way? That's ludicrous. I advise people to start reading the references that he's citing in detail, rather than taking him at his word. So far what I'm reading has been illuminating, but not in support of his arguments.

Great video! So many "experts" will say this food or that oil is toxic and must be avoided, and they say it with authority - and without evidence. I appreciate your evidence based approach to evaluating dietary components. After this video, I feel safe in using canola oil for light frying of my food or as a salad oil. Looking forward to more content!

[@lachlanscanlan5621]

"After this video, I feel safe in using canola oil" Until you research studies (the primary data of "experts") yourself then you have given authority to an expert yourself without any evidence

Thanks. Great info and wonderful that you backed it up with real research. Like to add that canola oil also has an excellent balance between omega 3 and omega 6 fatty acids.

[@jrb_sland]

Thank you, Dr Carvalho, for this high-quality survey of the evidence for/against canola oil. As an aging [75] Canadian man I'm proud of the fact that modern canola plants were bred/created/invented in the early 1970s at the University of Manitoba, and that Canada is the largest producer/exporter of canola seed oil in the world. The name "canola" was also invented in Canada to distinguish it from rapeseed oil, the name of which has unfortunate connotations. See Wikipedia for more...
