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

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.

Thank u so much for this video. I am sooo sick of the numerous utubers claiming that any oil other than olive oil is poison.

Severely underrated channel. The sheer depth to which you research these topics is unmatched. Thank you.

Incredible video. Can’t tell you how many videos appear on my social media feed saying that canola oil is poison but with no actual cited studies. We need to get this video out to the masses

What I like about the channel is that they always give you an overall big picture on the topic, with no cherry-picking.

I really appreciate that you took the time to make a concise long form and detailed video on this subject. Understanding the facts via study and trials is important. Excellent video, and I’d watch any longer deep dive video you do on things like this in the future.

The "influencers" telling us about poisonous seed oils have the advantage of dramatic soundbytes, so thanks for another measured response that has already gotten a comment about being too long! You always give a summary, so this is a non-issue.

Excellent video - thorough, quickly paced, no frills, just pure content and lots of it.

Great video! I have been following your videos for the last two months and have learned a few things. With pulling a lot a sugar out of my diet, 16:8 intermittent fasting, and going vegetarian on most weekdays I have lost 20 lbs., and my gut health seems to be a lot better.

I really appreciate your scientific approach to the topics you are discussing in your videos. There are too many alarmists and clickbait videos out there claiming one thing or another.

Thank you for the amazing work you do. Appreciate the depth and clarity of the data you provide.

As always, great content presented in an easy to understand format for the average person. I'm so glad your channel is finally getting the attention it deserves.

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.

I certainly appreciate all the research and effort that goes into producing your videos. Additionally, I very much enjoy your presentation. The pace and the positive, friendly attitude are very pleasant. Thank you.

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. I was always skeptical of these types of comments but at some point I did wonder if there's some truth to it. This video is a good reminder to always ask/look for evidence, especially for such extreme assertions 🙂

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.

This channel is so damn underrated!!!! Regardless of the topic, you handle it carefully without any bias. You rock!

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.

Hi Gil, I can't tell you how much your channel means to me. Recently diagnosed with Coronary Artery Disease and trying to work to find the best diet that works for me, your channel is an invaluable source that I always turn to. There are so many influencers out there, telling you this, or that, and I felt so confused. First I thought I was doing the right thing, then watching another video, I found I was doing wrong. I feel like I am settling into a diet that is most plant-based, with some animal products here and there, something that I feel is sustainable for me along with taking my meds. Thanks again for all your help, will always be watching your channel!
