  • 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

    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.

      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.

      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.

      ​@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.

      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.

    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.

    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.

    I want to see a study where they feed people deep fried food in canola oil for a few weeks. Do it with fresh oil everytime. This study is probably the most important because it studies one of the most common cooking methods. I suspect the sheer amount of oil that you ger from processed food and deep frying is the poison.

    Amazingly thorough video with interesting results

  • @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.

    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.

    @drott150 10 месяцев назад +2

    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!

    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...

    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.

(The smelly ones may have actually gone rancid but in some cases it was definitely the propellant or whatever.

    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.

There's very few that will change from what they believe or want to believe even if there is solid evidence to the contrary. And they will defend their misinformation to the end.

    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.
