Ok, so then why has america gone from lean (70s and before) to obese, at the same time sugar, refined carbs and seed oils were starting to appear in almost all foods?
Sometimes the answer is how not why. The why is that we're over consuming, the how is that ultra processed foods that have been ENGINEERED to be as palatable as possible for as long as possible contain a lot of calorically dense ingredients. Increased consumption combined with an increase in base calories of the food consumed equals we all got fat in the rapidly industrialising West.
@@biolayne1 So the increase in hearts attacks, diabetes and cancer can be related to an increase in calories on average a 1000 per day? So process food is not the issue but overconsumption is?
A deep dive video on saturated fat would be really beneficial IMO. Breaking down some of the epidemiology, replacement studies with refined/whole carbs etc and also looking at effects of differing sources (meat, dairy, butter, tropical oils etc) 👍
Search ‘David Diamond saturated fats.’ He has several videos exposing the fraud designed to demonize saturated fats. I suggest that the fats of pastured animals is better than GMO corn fed animals.
4-Hydroxynonenal (HNE) is by far the most investigated aldehydic end-product of oxidative breakdown of membrane n-6 polyunsaturated fatty acids. Its potential involvement in the pathogenesis of atherosclerosis has been corroborated by its consistent detection in both oxidized LDL and fibrotic plaque in humans.

same shit in my case. For starters I was more CICO flexible-diet guy. Then I came up on low-carbish approach, started being interested in it distantly. I thought that if you want to go insane, start getting know with nutrition subject. Subsequently I got really hard into a community that said even fruits and vegetables were poisonous. You know, fructose and all that shit. Then, more temperate attitude like Robert Lustig and got into him also greatly. And now Im ending up at the same point at Layne's channel
Great video. I'm convinced hyperpalatable foods with high energy density is the main problem with modern diets. Sugar, oils and processed carbohydrates are all partly to blame because they have such high energy density and it's hard to control adequate ingestion. I'm having great results with calorie dilution, loosing a lot of weight without any hunger.
Yup. It is very easy to over eat foods that are high in sugar/simple carbs, because they are so calorically dense and low volume. It’s okay to eat a little bit of simple carbs, but eat it with fresh vegetables and lean protein so you get full!
Sugar and carbs don’t have high energy density. They are 4 calories per gram. Fat is 9. What you mean to say is that the formulation of foods are hyper palatable these days, which causes overconsumption. You can’t say that carbs are energy dense. Even in instances where they have zero fiber, they’re not energy dense unless they’re packaged with fat.
@@boblangford5514Carbs aren’t calorically dense! By definition they are 4 calories per gram. Fat is 9 calories per gram. It doesn’t make sense to say that carbs are calorie dense. You can say that some carbs are easy to over consume, which usually isn’t even true unless they’re packaged with fat. Go ahead and see how much corn or bowls of white rice you can eat without any fat. Stop talking nonsense by saying they’re calorically dense.
2 points: 1. We don’t know the long term, even generational effects of lots of modern foods but we do know they can have effects (Pottenger 1942). Virtually all studies are very short term, certainly not generational. What’s your take on this line of thinking? 2. Avoiding seed oils basically means avoiding all modern hyper-processed food, which is good.
It's absolutely insane you are referencing Pottenger's experiments. I would argue his experiment didn't even have a real takeaway for modern food, but that's beside the bigger point that his experiment was completely debunked. The food he gave the cats lacked the essential amino acids cats require. The negative health effects were caused solely by malnutrition. Cats can eat cooked meats diets with those amino acids and not experience any health defects. It's studies like these that assume correlation is causation that causes misunderstanding with seed oils and many things like that. Just because 2 things correlate doesn't mean we should EVER assume 1 causes the other without proper research.
@@Klein-sb1th the point of referencing Pottenger isn’t that his experiment has some special insight, it’s to point out that we don’t know everything and sometimes things can have very long term effects that we won’t be aware of unless we have equally long term data. It’s a caution against the pretense of knowledge.
@@Dram1984 Pottenger's experiments had literally nothing to do with the long-term effects of a modern diet. It is literally a guy that malnourished cats because he lacked the knowledge of basic dietary needs. This is like saying "Humans got scurvy on pirate ships, so beef jerky must be bad for you" It is totally unrelated to the actual cause of the scurvy. You literally referenced Pottenger as an insight into the effects of modern food.
Cool thanks. Foods made almost entirely of refined grains, seed oils and sugar are some of my favorites. I will continue to purchase and consume them while controlling my daily calorie intake and getting lots of exercise.
But exactly why is this reused, reheated oil bad? Because it's all poly unsaturated oil. The heating (and reheating) causes the oil to go rancid, leading to ROS for those consume it. And ROS leads to chronic inflammation, and a cascade of downstream effects, including auto-immune diseases.
@@JimDon-xj5qpYes, he should've elaborated more on this instead of going quickly through it. Because guess what? All fast food restaurants do this, I can even say that most restaurants do this as well
Layne, obviously you're an incredibly qualified scientist and researcher however as someone from the comms field I find your ability to communicate such complex information by simultaneously making it relatable, relatively simple, fascinating and entertaining so very impressive. Admittedly I'm far more interested in health and fitness than astrophysics, however your skills as a science communicator remind me of the brilliant Dr Brian Cox who makes people smarter every time he opens his mouth. Thanks as always for cutting through the BS while respecting science.

I pay attention to scientists and dont enjoy practitioners of any bias who pretend to represent the science but are either ignorant or dishonest in favor of their own bias. This guy surely cannot see past his own bias, and sounds foolish to those who seek to truly understand the metabolic science. And he mis-represented the findings of studies involving different diets in order to sell his bias. Truly amazing. Instead he simply criticizes scientists who's findings do not support his bias. Here is real scientist. ruclips.net/video/L2fSaFnt0FM/видео.html This scientist was one time onboard with the High Carb Low Fat diet until the experimental science he and others were involved with produced results opposite of what the dogma in the medical community was telling everyone since the mid-1900's Also, scientists are not typically activists, but try to understand the truth in general. Practitioners tend to support what they are told. I see that happening here.
i found myself looking for chocolate covered pretzels that didn’t use seed oils, because seed oils cause inflammation and I realized how ridiculous that was.
@@General.Kappadin It's the small, thin, crunchy type of pretzel that they dip in chocolate, not the big Bavarian, doughy kind that you dip in mustard or weird cheesy goo.
I'd really like to see you talk with Dr Mike Israetel and Thomas Delauer about this specifically. I watch content from both, and I do feel like there's a lot of difference in the takeaway I walk out with, and there's probably a really important total conversation that you should all have in one video, together, with data, and conclusions and agreements/disagreements. It does seem like everyone is kind of on the same page, but the packaging makes it seem like everyone is going in different directions. Please do a collab specifically about this one.
Yes, it would be nice if multiple collaborators got in on these kind of videos,. I would include Dr Mark hyman, Dr Peter attia, and Dr Rhonda Patrick into the mix
LOVE IT! Tell it like it is! I m a family doctor, I'll definitely be sharing your channel and this video especially when my patients mention seed oils again. BTW you make a good point about the re-using of oil for frying and how unhealthy chemicals can build up. I lived in China for 10 years and there were plenty of food scandals, one of my "favorites" was the "gutter oil" (地沟油) scandal around 2011. Restaurants were supposed to throw out oil at the end of day; but many enterprising people would secretly collect the used oils in the middle of the night, then clean out the used oil particles using unhealthy chemicals, then resell the clean-looking oil to restaurants and in bottles for consumers. I literally would see these small tanker trucks driving around my Beijing neighborhood around midnight. "May you live in interesting times"...
I showed someone this video and they claimed I was "appealing to authority" for the fact that I would rather listen to Layne rather than the random commenters below his video. I find it pretty funny the length some people will go to try and not listen to any fact or opinion. No, I'm not appealing to authority, I'm citing my sources and listening to experienced people..
When I cut out seed oils and went on a high saturated fat keto diet, my C-reactive protein level tripled and LDL shot through the roof. Fortunately I was only on it for a short time bc it's a miserable way to eat and not sustainable. Additionally, healthy cell membranes and mitochondrial function absolutely require unoxidized Linoleic Acid. Too much saturated fat incorporated into membranes make them stiff. You'll never hear me advocating against unoxidized PUFAs or MUFAs.
How long were you on keto? if you were never fat adapted, your body might have been going through metabolic hell trying to adapt and re adapt from consuming low carbs
Similar experience here. I’m a lean, active 40y female and after a calorie controlled period of “ketovore”, my LDL DOUBLED and my Trigs increased. I changed my tracker settings back to “balanced” and in 7 days, my TC dropped 112 points. Fasting BG exactly the same and far more stable during the day. I shall continue with my 2 second Pam spray in my non-stick pan.
In Latin America it’s impossible to go a meal without the locals eating seed oils. Nearly every woman has cellulite, people walk slow, and they’re overweight. Every meal contains seed oils. If seed oils were so healthy they should show it in their physique. And their energy levels. They don’t however

Nutrition Made Simple has a good video where he goes into more detail on the overall evidence. But overall, great video and a good analogy with the mutual fund.
@segasys1339 only time I have seed oils is at restaurants, dont even have any in the house 🤷♂️ not gonna completely avoid eating out because of scare tactics tho
i think the best argument against seed oils is that theyre not "good for you" as in, theyre mostly empty calories, especially the hyper deodorized refined stuff, while stuff like olive oil and avocado oil is packed with goodness, from beta carotenes to anti oxidants etc. and also.. it just tastes way better. Seriously, theres a reason no one drizzles canola oil on stuff, it tastes like nothing.
IMO the main issue is that it's a lot more entertaining and engaging (and honestly potentially easier for people to comply with) to tell people that certain foods MUST be avoided at all costs, then to tell them a nuanced idea that some broad categories of food should be eaten frequently and some foods should be eaten less frequently. The latter is a pretty healthy way of eating but less attention-grabbing
Boring truth: seed oils are fine, but you probably eat too much of them. Salacious lie: seed oils burned our crops, poisoned our water supply, and spread a plague unto our housed! You bring up a very good point -- it's easy to imagine why idiots are more attracted to one of these two narratives, against all evidence. It makes them feel woke.
I saw one particular video where he was doing it screaming like a lunatic and you clearly see a lady in the background wanting to go down the isle look scared and take off in the other direction.
According to the internet they're either cold pressed, hot pressed, or solvent extracted. two of these methods don't result in high heats and none of them result in heating and cooling them MANY times. Plus he says even then there's not great evidence to support it
Yep, and thats why I dont trust these test studies. Your own body will tell you all you need to know. Eat foods that keep you satiated for longer, so that you energy intake will never get high enough to make you obese. In my case, there is only long chain saturated fat that makes me full and keeps my mind focused and in good health.
Sesame seed oil is the oldest cooking seed oil and goes back 10,000 years and it reduces inflammation in multiple studies. Most seed oils are over processed and trash but some are beneficial. I still rather have olive oil and grass fed butter/ghee. They also go back 10,000 years
I am concerned about the trace amounts of hexane in processed seed oils. Hexane is an industrial solvent and even trace amounts should not be tolerated. Double-blind trials do not help detect problems which occur when you eat trace amounts of toxins for decades. I believe that moderate amounts of ghee and olive oil are much better options.
Exactly, I don't believe any of those So called clinical trials. None of them are conducted for decades. Most of them are done for months. You can be totally fine with KFC and McDonald's for several months. 😂 It is so simple. But people don't get it. You shouldn't wait for clinical trial to stop eating refined oil and sugar. There are better options anyway.
I am totally on board to not get dragged from biased health influencer and “studies “ that support their theories. I can feel your frustration. As Italian I still don’t use any seed oil, but it’s just culture I guess. Back home we fry (very little) in lard or peanut oil (last 20 years) and we use mostly extra virgin olive for everything else, little butter here and there. Along with eating a veggies, fruit and grains rich whole foods omnivore diet . I moved to Canada in my 30’s and the shock I got from seeing how much more ill people compare to Italy it’s impossible to erase. Will never abandon my Mediterranean lifestyle ❤😂
Ironically, YOUR BEST video to date. I have a UCLA Bio Degree and sometimes leave idiotic messages just to amuse myself. The Paul Salad*ino impersonation should get you an Emmy. Great info buddy.
Nice one - thanks for crunching through the papers so that I don’t have to… PS - I hope this one does really well so that you can afford a bigger T-shirt 😉💪🏻
If he truly 'crunched through the papers' he would see that study after study debunks his views on saturated fat. There is no correlation between saturated fat and heart disease or cardiac events. This has been born out by multiple studies and evaluation and debunking of studies that said there was a causation. Layne is not the 'be all, end all' of nutritional science. There are just as many qualified individuals in his field who are saying the exact opposite of Layne regarding seed oils and saturated fat. And they have the studies to back up their information as well. We must discern and sift, compare and contrast.
@@guibox3 I have atherosclerosis, the conflicting research does my head in 🤯 but I do appreciate that he gives links to his sources. I would like to hear what is @biolayne1 opinion on the work of Prof Tim Noakes et al.
Great video. But speaking on the saturated fat portion of this video, the Journal of American College of Cardiology wrote in a study in August of 2020: “Several foods relatively rich in SFAs, such as whole-fat dairy, dark chocolate, and unprocessed meat, are not associated with increased CVD or diabetes risk. There is no robust evidence that current population-wide arbitrary upper limits on saturated fat consumption in the United States will prevent CVD or reduce mortality.” Thoughts?
NutritionMadeSimple, an MD and PhD in nutrition science, discusses saturated fats in detail and the range of good to bad sat fats specifically chocolate, dairy all the way to beef fat here: ruclips.net/video/mBFe1QattAU/видео.html
Yes. So many people on here saying, 'Yeah, this 'seed oil is bad' is just nonsense', will readily believe that 'saturated fat is bad for you' when study after study shows no correlation between saturated fat and heart disease. Apparently to Layne and other gullible people, canola oil is healthier for you than saturated fat found naturally in our meat and foods. Sounds like they are still brainwashed to me. The last 40 years has shown that this advice has made us sicker and fatter. Not sure why Layne seems to think this is scientifically sound nutritional advice.
Quite simple. Foods are different, in part because of the varying fatty acid composition in those foods, and the other chemicals they contain that interact with them. Try looking up the food matrix effect.

Excellent video thank you for being evidence based. Couldn’t agree more. Noticed these same sorts of obnoxious unsubstantiated claims on social media. Keep it up Layne.
Seed oils are used in everything which causes everything to be entirely way more dense. You also brought up seed oils are bad in excess but they are used in absolutely everything when you go out to eat, or get snacks
They aren't used in everything, not even close. Yes, they are used in a lot of restaurant food, but I think that's part of the point; should we be going out to eat all the time? (no)
If you are eating good whole foods most of the time within your caloric needs, then it will make no difference. You can't eat donuts and fries all day and say they are in "everything".
Layne, I go back and forth on this. You have to take a better look at these studies to measure exactly how much PUFA people were consuming in these randomized trials and match it up to the real world consumption. Yes, energy toxicity agreed, but is there more to it? Remember the TRANS FAT was undeniably toxic and atherogenic (finally banned by USDA Jan 2020). Wouldn't it just make better sense to eat the foods that these oils come from rather than extracting the oils through a scrubbing process involving chemical and heat denaturants which can oxidize the myriad of unsaturated bonds in the fatty acid molecule (with a side product of toxic aldehydes)? In essence, isn't that what was done intentionally by hydrogenating the TRANS FAT? Manufacturers know there is truth to what I'm saying, otherwise, why would they be going to lengths to sell the "expeller pressed" oils if science was on their side with previous methods? The verdict to me is still hanging. I would counsel people to as much as possible stick to a whole foods diet, avoiding overly processed foods.
You discuss replacing saturated fats with Seed Oil, but I think most (looking to be healthy) would be more interested in the advantages of replacing Seed Oils with Olive , Avocado oils (higher in Mono than Poly or Sat fats) and what control studies show are the advantages of that substitution. Thanks for all you do !!!
Studies suggest polyunsaturated fat might be even better than monounsaturated fat regarding the prevention of CVD. Regarding inflammation there is no difference or at least the studies didn’t seem to find any. I use Olive oil mainly because I love the tase but I don’t mind seed oils either.
I personally want to keep my saturated fat intake as low as possible while keeping my omega 3,6,9 as high as possible so I can get the most nutrients out of the calories from the fat. Olive oil is a good option but I also like my canola oil
I did that and biggest thing I've noticed is that I've gone the entire year without getting sunburned. Polyunsaturated acids oxidize more easily that saturated or mono when exposed to UV and that oxidation of the fatty acids in your skin is what causes sunburn (and possibly cancer.)
I’m a carnivore and I am no fan of plants or seed oils for that matter, but I liked this video. Ive never found the arguments against seed oils very compelling, but I stay away from them anyway because they were part of the problem back in my overweight days. I eat the way I eat because I can adhere to it and thus keep the weight off and progress toward my fitness goals.
@@rontiemens2553Same here. I don't add oils to foods either but neither do I add butter or other animal fats. I only eat fat that naturally comes with meat and eggs
When I eat seed oils, my gut inflammation kicks into full gear and I’m miserable. When I cook things in beef tallow, butter, EVOO, I feel amazing. Been living with Crohn’s for about a decade now and eliminating carbs and seed oils from my diet has helped me stop taking weekly injections. Haven’t felt this good in years and I finally have my life back just by changing my diet. In the process I’ve lost a lot of weight too. Doctor Robert Lustig, right here on RUclips, has a lot of insightful information about how unsaturated fats chemically change when under extreme heat and pressure alone, which is what every seed oil needs to go through to become “edible”. He breaks down the exact science of why it occurs and how it negatively affects your body. Labeling natural saturated fats as unhealthy, the fat that oxidizes the slowest by far, has been one of the biggest metabolic mistakes doctors around the world have pushed.
This is exactly why I’m watching this video. I recently started eating seed oils again and I noticed I feel so heavy and gross after. I wonder why it affects some people like that if the studies don’t show it having a negative effect. I didn’t know the food had seed oils in it but after feeling crappy I asked and it turns out they cook with seed oils.
Is there a chance that you were eating less calories when you swapped seed oils and carbs for saturated fat and therefore you lowered inflammation because losing fat does that?
@@JoshYarlett I did not alter how much I was eating, just what I was eating. It’s incredible how bad I feel after eating things cooked in seed oils. It’s like going from 0 to 100. My stomach begins to cramp the next day, my heartburn instantly comes back, and my 💩 is loose and/or diarrhea - which is a clear sign of intestinal inflammation
@@rg975 I honestly don’t know what that could be but I’m not an expert. I guess seed oils just don’t agree with your system in which case then yeah probably limit them

Total calories consumed per capita in Japan have DECREASED since the 1960's. Sugar per capita has DECREASED in Japan since the mid 80's. Diabetes, obesity and CVD have all skyrocketed in that time, so what could it be? Use of seed oils has skyrocket in that time from average 90 cals per person per day in the 1960's to 400 calories today. Today in Japan the average diet is 1,850 calories down from 2,837 in the 1940's so they are now getting 22% of calories from seed oils compared to 3% in the 1940s. This is DAMNING. Also, you are switching subject by pivoting away from seed oils to saturated fat. Stick to the topic, seed oil use has skyrocket in EVERY developed country where CVD/diabetes and cancer has increased dramatically. Now look at the US. Sugar per capita has DECREASED in the last 30 years. Obesity and seed oils have continued to skyrocket. Now look at Australia, sugar has been DECREASING since the 1960s but obesity and seed oil use has been skyrocketing there. Now look at China, sugar hasn't moved much at all in the past 100 years but the entire population switched from using animal fats to seed oils to cook three meals a day (virtually 100% switched from animal fats to seed oils)....and disease and obesity has skyrocketed there. Literally EVERYWHERE you look you see skyrocketing disease and obesity when use of seed oils increases, usually in tandem with declining animal fats.
See how much you have to type, creating all of these copes, instead of posting EVIDENCE? What do randomized control trials show? They show you people are crying over nothing. The same people crying about seed oils, are fine with gallons of animal fats a day.
@@vashlash6870 so it has to be a lab in order to be proven to you? just look at how Americans ate in the 1960's and how skinny they were, compared to Americans in the 80's. Layne wants to blame the excess calories, and people becoming more sedentary (which isn't true), when there's been a massive switch in the ingredients used, not the caloric intake. In the Minnesota starvation experiment the subjects were started at 3,200 calories, which was considered the average caloric intake for a 150lb man, then they slowly reduced it over time to 1,500 and they became emaciated and their organs shrank. Point being, the average intake was HIGHER in the 1960's than todays 2,000 calorie diet. Just go watch a video on how seed oils are concentrated and then decolorized and de-scented, tell me that's natural. You don't think Layne was probably paid off by the seed oil companies to make this sort of video? You really think he's putting out this sort of video just to 'disprove' the carnivore camp?
your assumptions are exactly opposite, asians are eating more saturated fat today than ever, their previous diet had less animal products and has increased in animal products since the 1960s.
@@mattvdhyou clearly don't understand how, or why, science works. Appeal to naturalism; check. Baseless accusations of corruption and collusion with "Big Seed Oil"; check. All to protect your cozy narratives.
As a biochemist who had to study metabolism and investigated the refining methods of seed oils to educate myself on the matter, I can confirm that these anti-science conspiracy theories in the comment section are worse for my health than the jug of canola oil I sear all my meat and vegetables in.
Dr. Norton i just recently found you and saw stone new videos of yours, now some older ones like this. Don't take it the wrong way but by seeing you in the thumbnail i was like oh no not another "muscle headed" carnivore "Dr"! When you have opened your mouth my perception quickly changed as you are anything but! Kudos! Commenting & liking to boost your channel!
After finishing this video I've realized my comment under the pinned one was partially superfluous. And there are some things I'd like to add: I like your humor in the middle. In some cases you can only do epidemiology, in vitro and in vivo animal model studies. Unless your last name is Mengele or your team have the number 731 attached to it. (Or their less talked about Antant counterparts...) You have to be happy if you make THOSE kinds of people angry. What I missed in this video: You should have mentioned that all seeds and seed oils aren't created equal. Far from it! For example Rapeseed and Sunflower vs. Palm and Coconut oils are night and day. And especially true for palm oil as it isn't only bad for your body for multiple reasons but also terrible for the environment. Tons of species go extinct due to the plantations including one of the cutest elephant species of all. And they are objectively feeling, intelligent, sentient and most likely sapient brings with very human like but probably even more complex language systems. Coupled with a wide range of cultures, customs, celebrations and ceremonies. Maybe even religions as the ancient thought they had (written in classical Greek, Egyptian and Roman literature... Sun God worship centered religions according to their beliefs). And they are the only non human animal sibling known for us that gives their members their personal given names according to human logic, contrasted to other, balls different but not necessarily less complex naming customs and traditions of cetacean and bird and other non human ape species. As far as we know it today off course, but we are in the very beginning of non human language and culture research. Probably you have videos on the effects of different kinds of seed oils on human health but a couple sentences long mention here is needed IMO. Most people haven't watched all your videos. I hope you don't mind this constructive criticism from my part. I'm sure you wouldn't add you came across more intelligent than that. I only edited this comment for correcting some swypoes for clarity.
Yeah. I'm trying to avoid tings that are overly processed. I learned I have a lot of inflammation and most likely an autoimmune disorder by now and I don't eat sugar and fried foods,. But seed oil is in everything - every other health food even. I was informed to avoid processed foods.
@@user-rf2fv6tf1p Yes. I understand that. I mean in general - the real crap stuff out there . As well, a lot of health foods are hard on my stomach - like those Macro bars. I had a stomach infection and my immune system over responded to it, and I can't eat a lot of things now even months later.
Yes. Nutrionmadesimple is awesome. He communicates nuances well too. He name checked Layne also. Travesty of media why Saladino’s carnivore diet goes viral and quality science channels like these guys don’t as much.
I appreciate the break down with emphasis on randomized clinical control trials. I’m curious how the comparison looks with omega 3 rich cooking oils like Avocado or macadamia oil vs PUFA or Saturated fats. The latter 2 are not the only cooking oil options.
Yeah I'm disappointed that he didn't go over the full spectrum of oils. The data is clear that a magnetic 3, 7, and 9 do benefit health far beyond other oils. However, even too much omega-3 can begin to be detrimental.
@shiftgood It’s the fact you’re eating an unreasonable amount of French fries, not the fries themselves. But of course let’s scapegoat instead of looking at ourselves. That’s easier.
I've dived into a few studies, mainly meta-analyses, that I've seen referenced in videos like this which take the anti-saturated fat (mainstream) PoV. Somehow they never quite check out. For example, you see studies which indicated lower cardiovascular events with lower saturated fat, BUT in the fine print you discover that all-cause mortality was not improved. And for example, in the "sat fat increases lung cancer" study linked in this video description, the fine print showed that sat fat consumers who never smoked did not have have statistically significant increase in lung cancer. Every single study I've looked at has major holes in it like that. So I'll stay open and keep researching. But I'm not convinced of the mainstream PoV that completely novel industrialised oils are magically better for us than ancestral diets. There is a LOT of money from industry pushing this, from both big agra and pharma, so the burden of proof rests with them and I'm not convinced it's there.
@@RaveyDaveyStrong words. Why does Big Processed Plant Foods conduct many times the studies than the govt? To lose money? How long does it take to get a heart attack from a bad diet?
@@RaveyDavey that's not what is showing up in these studies. What is showing up is increase in cv events but decrease in cancer. Eat seed oils get cancer, eat sat fats get CVD. That's how total mortality seems to even out. However the main confounding factor is that sat fats have been demonised for 70 years so most people who eat more of them are lackadaisical about their other health habits, such as exercise, alcohol, sleep patterns etc.
Seems Layne is the type of guy that only reads the abstract and thinks he is the smartest guy in the room. Was checking the studies he referenced and noticed questionable research methods relative to Layne’s claims. For example, in “Overeating Saturated Fat Promotes Fatty Liver and Ceramides Compared With Polyunsaturated Fat: A Randomized Trial”, they used palm oil (50% saturated) as saturated fat and sunflower oil as PUFA, both are highly industrially processed vegetable oil that gives no context as to the comparison between natural saturated fat in animals vs processed seed oil.
Thank you Dr. Norton. What are your thoughts on the Minnesota Coronary Experiment and the LA Veterans Administration Study? Seems the vegetable oil consumption is correlated with shorter lifespan. Thank you.
No mention of omega-6 to Omega-3. No mention of seed oils originally being used for industrial machines. No mention of how diabetes was not as prominent before seed oils before the 1950s. The nuance nutrition science RUclipsrs will have plenty to discuss after this video. However this video was a good move for the algorithm to shake things up.
I have a sincere question. Are the health benefits of carnivore diet coming STRICTLY from eliminating potential triggers? Why are people experiencing life changing symptom relief (gut issues, mental clariry, joint pain, skin health, and increased energy)? If elimination diet is so powerful and healing, why is it that only carnivore diet is known to be effective? I understand that studies are important, but I have witnessed people and read thousands of anecdotal storires of the benefits and i am very confused. Also, do you think that the USDA guideline on the ratio of macronutrients are health promoting and that as long as we eat less calories then we would be healthy?
Probably cause proccessed foods are bad, and if its just meat that isn't heavily processed yes they will be healthier than those who do eat crappy processed meats but those who are whole food plant based are healthier than non processed meat eaters🤷♀️...
How long has humanity been consuming fried food? And how much fried food do we consume? Layne, I'm not pointing the finger at you, personally, but science has no excuse whatsoever for dropping this massive ball. There should be zero ambiguity over the use of reheated oils for frying. Zero. It's an effing embarassment.
With 'that' image next to his name, it is kind of hard to take him seriously. There is a difference between looking good and health. Muscle heads tend to die early, right?
No hate! Love the clear communication. Thx for cutting the crap. It’s scary when Drs of any type (Gundry, Saladino, Berg) become money hungry influencers. Makes me sick.
This guy does nothing more in these videos than parrot "THE SCIENCE" with an arrogant, superior, know it all, demeanor which in the end may or may not be accurate.
The issue with these seed oils debunking video is they approach it in narrow one sided view (same with the Nutrition Made Simple video). This video doesn't even talk about the subject in question, but wholly about why saturated fat and too much calories are bad.
Okay... agreed! Too many "calories" ... BUT, for my husband and I, as we are fast approaching our 7th decade of life ... we have noticed increased soy, hydrolyzed and partially hydrolyzed palm oils, modified corn starch, corn syrups, and maltodexrin, (among other useless ingredients) added to our "foods" today, along with "natural flavors" added to Earl Gray teas, and more, which INCREASE calories, compared to what we consumed 50 years ago! This is one Dr. Lustig revelation with which we simply must agree, as we have witnessed this ourselves!
Imagine describing people who advocate a healthy and natural diet that has been followed by humans since the beginning of time as “haunting the industry”, because they don’t consume bottles of Wesson “vegetable oil“
Yeah a random guy who might make 40k in RUclips advertising in 3 years is who we have to worry about. Not the food industry that puts seed oils on 95% of all US products. This all started in the 1900s when they realized they can press cotton seed and make oil. This was at industrial factories and moved to food. It’s a money game. Human beings aren’t supposed to eat oils from seeds. It’s not healthy. You’re being played like a fiddle. A random RUclips doc isn’t who you should be scared of 😂😂😂😂
It's not just influencers. I'm quite literally a nobody on youtube and I can vouch for the effectiveness of removing seed oils from diet. I'm quite content with my personal knowledge and will simply wait for the science to catch up with my experience. I know I'm not alone, but even if I was: I'd be totally fine with that.
Substitute "seed oil" for toilet paper. I'm pretty sure we could eat toilet paper, and it would have a net neutral impact on our physiology. Mix it into our mashed potatoes and soups. Let's say everyone starts doing this, And it starts comprising 30% of human intake. Intake which COULD be occupied with nutrient dense, protein rich food. Then one day, after you realize while you feel full after you eat, you're starting to develope deficiencies. Skin starts breaking out. You're not poopin' right, and your breath smells like Charmin. You take to the Internet to tell everyone you're DONE eating toilet paper! It's not natural, and by replacing it with whole foods, your symptoms have improved. Suddenly, pro-toliet paper influencers start attacking you as a "grifter" for advocating what can only be described as more species appropriate diet. That's where we are. At BEST seed oils are nutrient filler, even by Layne's own argument. At worst we're consuming excess amounts of linoleic acid and Omega 6s, not to mention an overabundance of calories in the way of FAT. I'd rather eat toilet paper.
@greul_vietii yes This over simplification is like telling someone who is depressed to just be happy. Shit doesn't work like that and I bet those who spew this "eat less , move more" are the ones who have never had issues with weight in their entire lives. Go look at someone like Dr Nadolsky who is an obesity specialist, you may learn something
To be fair there is also issues of satiation and satiety. I've seen in my country how the food environment got worse and worse. In the current food environment you have either to control yourself (I wouldn't and wasn't able to do that - but some are less effected by it) or you have to change your diet (I adapted to pretty much the diet my grandparents ate and grew up in - now I need no control and can stuff myself until I'm full). And in terms of food volume I eat a lot more than I ate when I had trouble controlling my weight and were hungry constantly. My grandparents grew up in a country where they didn't have to control their food intake or change their diet. While every individual can still make a change for their health, the reason it spiraled out of control on a societal level is a environmental issue in that society.
@@DarkAbyss9 A similar analogy wouldn’t be “be less depressed”. It would be “go out more”. I eat less you and move more you lose weight. If you have insulin problems that doesn’t stop cico. Just take your meds and start exercising.
Hey Layne, thanks for posting this video - I was hoping you would do one on seed oils. My further request would be, could you take a look at Dr. Cate Shanahan's videos, and give your take on the mechanisms she cites as to why/how seed oils are causing problems in our diet? Again, appreciate your take on these things, as it is very difficult for those of us not educated in this area to figure out who is right, or find a unifying theory that explains everything.
If the issue was just calories in, calories out, people would not have the issues losing weight that they do. The mechanisms and underlying metabolic interference from these novel foods are being underplayed by the research. Dr Layne, I appreciate that you are backing your opinion up with research. But: What you need to understand is that the scientific communities politization has rendered studies supporting controversial topics dubious at best. Are you looking at whose funding this research? Are you considering the replicability crisis? Are you considering the fake paper crisis? I'm sorry but "peer reviewed study" doesn't mean much anymore, until the problems in academia have been fixed.
the idea america has this humongous obesity crisis, and that it would be because of "surplus of calories", is ridiculous. its a big food lie to have people not question the quality, but focus on the quantity. i would bet if we banned seed oils from our food supply, the 90% of the obesity epidemic would resolve over 4-5 years.
@@tallesttreeintheforest it would take a little more than just the seed oils, need to get rid of the endocrine disruptors too. No roundup on crops, no plastic food packaging, no teflon pans. No articifial dyes or flavors. No flouride in the water. But if we did all that, obsity would resolve in like a year, and Big Pharma would go bankrupt.
3:20 is exactly why seed oils are attacked. You’re playing reasonable fencesitter. It’s gonna get hate from everyone. You’re not wrong but I also think you’re being kinda lame.
Hi, I was in nutrition science decades ago and in general this was not the consensus in research but more in the headlines. There was also not a clear understanding of the role of dietary cholesterol and cholesterol in the body which made it valid for the time as a precaution. It is still also valid for those with hypocholesterolemia and those that have intake patterns outside of a normal dietary range.
@@Ryan_Decker Response to dietary cholesterol is individually varied. Overall it is not good but, as for someone like my uncle, ingesting approx. 1600 mg. of cholesterol from eggs like you do can be life threatening for him.
i think the most important thing to remember about the seed oil debate -- and almost any debate is that just because a study shows that majority people do not get more sick from seed oils, there are some outliers (which could end up being YOU) that aren't considered and are drowned out in the average data that skews towards seed oils being healthy. Not every single person in a singular study benefited from seed oils and some did get sick. So just take into account how you feel after eating certain foods and listen to your own body and take studies into consideration but not as instruction manuals.
I'd say it depends on what you mean by "bad". Bad for you? Well, as stated in the video: not necessarily, saturated fat seems to be more of an issue. Bad for environment, pollution etc? Perhaps, but that's not something that the video addresses. Here we're purely looking at the health impacts of them.
@@kkrizzz I speak about REFINED oils. If you have to use chemicals to make a product stable, it doesn't seem right to me. We can take jus Hexane alone. I don't think this experiment is going to be beneficial in a long term. And it is very hard to define issues with saturated fats as the refined oils are everywhere, so it is not easy to do a proper RCT research in a long run. Epidemiology is better than nothing but far from conclusive.
Is there any truth to omega 3 : omega 6 ratios? I never hear you talk about omega 3 supplementation. Is it worth it? I remember it being big in the paleo community many years ago.
It’s only true within the context of a diet that does not supply arachidonic acid and DHA. In other words, if your diet counts on converting the precursors to the active forms, then the ratio matters, because that dictates enzymatic competition. However, if you consume eggs, liver, and fatty fish fairly regularly, then the ratio is of no concern.
@@tresero2862 the question was does omega 3:6 ratios matter. You said no because paleo is a joke. How does the status of paleo (weather it is a joke or not) affect if omega 3:6 ratio matter?

I've been concerned about the inflammatory effects of seed/vegetable oils for a long time. Long before it was a rash on RUclips. That said, I appreciate your breakdown. My bias will continue to favor other cooking oils (and butter), and obviously this doesn't mean I can go out and eat tons of chips.
Not really, he's prone to calling many other people phonies and being on his high horse. Look how he used to treat Thomas Delauer and the amount of time it took for them to collab because Layne refused to think of him as someone trying to seriously learn more. Layne was clearly the prideful one in that scenario. Layne definitely knows a lot and is a voice to listen to in order to learn, but he's not the arbiter of truth. I think it's also valid to be skeptical of anyone who claims that all they do is "data over dogma". It's from another field, but there's a linguist and ancient historian scholar called Dan McLellan, who claims to be the opposite of dogmatic, yet when you see his content up close, his "data" tends to line up with his political opinions and biases that he refuses to acknowledge. I think Layne is better than that, but *nobody* is free from bias.
@@carlosjosejimenezbermudez9255 No one person is the arbiter of truth and Layne has definitely been overly combative in the past, I agree. Still, his way of cutting through the social media BS and food disorder gurus that are running rampant right now is a something that is sorely needed. Anyone who has clicked on a few diet videos is getting bombarded with content that makes you afraid of eating pretty much anything at all, regardless of whether or not it has a detrimental effect on you. The hyper-fixation on out-of-context mechanisms on a cellular level is dangerous and Layne's stock analogy is spot on.
@@TC-by3ilI agree - many of the spread information is dangerous. A healthy diet and lifestyle is the key to disease prevention. And it is great when people are willing to invest their time and resources, researching what to do and eat best and unfortunately end up on a video of one of these fearmongering individuals that spread misinformation. I mean people in the comments are writing that the stoped prescription medications and are proud of rejecting their advice on medication and diet, believing the diet will fix all their medical problems. This is madness, and there needs to be some reasonable creators in the area of nutrition and fittness on RUclips.
Science is flawed, despite being helpful. Ultimately, I like to focus on personal experience. When I follow Dr Saladino’s animal based diet, the gut problems (diarrhoea) and psoriatic arthritis that I have experienced for decades completely goes away. I have been following Dr Saladino‘s diet for two years now, and it has transformed my life. I am a medical doctor, and medical science with its RCTs simply provided me one antiarthritic drug after another, which would provide relief for some months to years before eventually fading away. I am now resistant to just about every drug on the market, but there is no sign of Dr Saladino‘s diet stopping working for me. One personal observation I have made about the mechanism of action is that when my gut health improves my arthritis likewise improves, and my gut health is so much better on Dr Saladino‘s diet. I’m not clear which part of the diet helps, but it is without question that it works for me.
yes, would suggest googling it- but generally any of the oils that will come virgin/extra virgin exist without extreme processing to acquire them. ex. squeezing olives gets you olive oil thats ready to eat vs. a canola that requires heating/pressure/bleaching/deodorant/chemical additives/another 10 steps to make an oil edible
@@hagaigat there is no such thing. If a label says that it may be a blend of olive/canola. if that is the case you are getting bottom shelf versions of both to make a cheap blended product
Paul Saladino has responded to this video with facts and data with a THOROUGH deep dive in the meta-analysis Layne uses here. I have to say it again: Layne is in over his head here and DOES NOT understand the fundamental argument. Layne's breakdown and research is undergrad level. Paul's breakout is a true deep dive into the component case studies used in the meta-analysis. If you haven't listened to Paul's evaluation of the bio-mechanics of what's happening here, you, like Layne, are wading in the kiddie pool. This goes so much deeper than what's being presented here. Layne: Sir, if you ever want to be taken seriously in this space, you will need to put yourself out there and debate Saladino. You're still playing checkers and Paul has you mated in 3 moves. I think you're a smart enough guy to understand and acknowledge your mistake. Now.. whether you have the ability to swallow your pride and publicly admit it, remains to be seen. You can very easily repair your credibility with a smidge of humility.... Everyone will be better for it. Good luck to you.
@@Littlegoblinfatface "beta comment"? yikes. peak cringe. Because commenting on a RUclips video is a good marker for masculinity right? Btw: Paul ain't just "some dude" and if you haven't heard of him you're nobody I really care about in this argument. Now go sweep a motorpool or something...
Ok, so then why has america gone from lean (70s and before) to obese, at the same time sugar, refined carbs and seed oils were starting to appear in almost all foods?
Because average daily caloric intake is up by almost 1000 calories per day on average. That. Fucking. Simple
Sometimes the answer is how not why. The why is that we're over consuming, the how is that ultra processed foods that have been ENGINEERED to be as palatable as possible for as long as possible contain a lot of calorically dense ingredients. Increased consumption combined with an increase in base calories of the food consumed equals we all got fat in the rapidly industrialising West.
@@biolayne1 So the increase in hearts attacks, diabetes and cancer can be related to an increase in calories on average a 1000 per day? So process food is not the issue but overconsumption is?
@@andreasansotta4974Ffs yes, overeating is the problem how hard is that to understand
@@andreasansotta4974correct, that is what the science has shown over and over
A deep dive video on saturated fat would be really beneficial IMO. Breaking down some of the epidemiology, replacement studies with refined/whole carbs etc and also looking at effects of differing sources (meat, dairy, butter, tropical oils etc) 👍
Search ‘David Diamond saturated fats.’ He has several videos exposing the fraud designed to demonize saturated fats.
I suggest that the fats of pastured animals is better than GMO corn fed animals.
No, saturated fat is not bad for you. Yes, you can have too much of it (and most people are having far too much of it). There you go.

Dang. That is actually very true!
Great video. I'm convinced hyperpalatable foods with high energy density is the main problem with modern diets.
Sugar, oils and processed carbohydrates are all partly to blame because they have such high energy density and it's hard to control adequate ingestion.
I'm having great results with calorie dilution, loosing a lot of weight without any hunger.
Very intelligent comment. I agree with you 100%
Yes, sir
Yup. It is very easy to over eat foods that are high in sugar/simple carbs, because they are so calorically dense and low volume. It’s okay to eat a little bit of simple carbs, but eat it with fresh vegetables and lean protein so you get full!
Sugar and carbs don’t have high energy density. They are 4 calories per gram. Fat is 9. What you mean to say is that the formulation of foods are hyper palatable these days, which causes overconsumption. You can’t say that carbs are energy dense. Even in instances where they have zero fiber, they’re not energy dense unless they’re packaged with fat.
@@boblangford5514Carbs aren’t calorically dense! By definition they are 4 calories per gram. Fat is 9 calories per gram. It doesn’t make sense to say that carbs are calorie dense. You can say that some carbs are easy to over consume, which usually isn’t even true unless they’re packaged with fat. Go ahead and see how much corn or bowls of white rice you can eat without any fat. Stop talking nonsense by saying they’re calorically dense.
2 points:
1. We don’t know the long term, even generational effects of lots of modern foods but we do know they can have effects (Pottenger 1942). Virtually all studies are very short term, certainly not generational. What’s your take on this line of thinking?
2. Avoiding seed oils basically means avoiding all modern hyper-processed food, which is good.
Exactly. All these followers of Scientism think we know everything from short term studies.
It's absolutely insane you are referencing Pottenger's experiments. I would argue his experiment didn't even have a real takeaway for modern food, but that's beside the bigger point that his experiment was completely debunked.
The food he gave the cats lacked the essential amino acids cats require. The negative health effects were caused solely by malnutrition. Cats can eat cooked meats diets with those amino acids and not experience any health defects.
It's studies like these that assume correlation is causation that causes misunderstanding with seed oils and many things like that. Just because 2 things correlate doesn't mean we should EVER assume 1 causes the other without proper research.
@@Klein-sb1th the point of referencing Pottenger isn’t that his experiment has some special insight, it’s to point out that we don’t know everything and sometimes things can have very long term effects that we won’t be aware of unless we have equally long term data. It’s a caution against the pretense of knowledge.
@@Dram1984
Pottenger's experiments had literally nothing to do with the long-term effects of a modern diet. It is literally a guy that malnourished cats because he lacked the knowledge of basic dietary needs.
This is like saying "Humans got scurvy on pirate ships, so beef jerky must be bad for you"
It is totally unrelated to the actual cause of the scurvy.
You literally referenced Pottenger as an insight into the effects of modern food.
Let me ask you this. Has cardiovascular mortality increased or decreased over the last generations?
Cool thanks. Foods made almost entirely of refined grains, seed oils and sugar are some of my favorites. I will continue to purchase and consume them while controlling my daily calorie intake and getting lots of exercise.
I can tell you that the vast majority of fried foods you're getting from a restaurant come from old dark oil that's been reheated many times
YUUUUUUUUUP. Only thrown out every few days. Oil that gets dark very quickly over the course of a single day.
@yourDoom8 yeah that's gross. that's really bad.
Yep, another reason I don't like eating out. And I know this is not "nice" but I especially avoid the mom-and-pop restaurants.
But exactly why is this reused, reheated oil bad? Because it's all poly unsaturated oil. The heating (and reheating) causes the oil to go rancid, leading to ROS for those consume it. And ROS leads to chronic inflammation, and a cascade of downstream effects, including auto-immune diseases.
@@JimDon-xj5qpYes, he should've elaborated more on this instead of going quickly through it. Because guess what? All fast food restaurants do this, I can even say that most restaurants do this as well

I pay attention to scientists and dont enjoy practitioners of any bias who pretend to represent the science but are either ignorant or dishonest in favor of their own bias. This guy surely cannot see past his own bias, and sounds foolish to those who seek to truly understand the metabolic science. And he mis-represented the findings of studies involving different diets in order to sell his bias. Truly amazing. Instead he simply criticizes scientists who's findings do not support his bias. Here is real scientist. ruclips.net/video/L2fSaFnt0FM/видео.html This scientist was one time onboard with the High Carb Low Fat diet until the experimental science he and others were involved with produced results opposite of what the dogma in the medical community was telling everyone since the mid-1900's
Also, scientists are not typically activists, but try to understand the truth in general. Practitioners tend to support what they are told. I see that happening here.

LOVE IT! Tell it like it is! I m a family doctor, I'll definitely be sharing your channel and this video especially when my patients mention seed oils again. BTW you make a good point about the re-using of oil for frying and how unhealthy chemicals can build up. I lived in China for 10 years and there were plenty of food scandals, one of my "favorites" was the "gutter oil" (地沟油) scandal around 2011. Restaurants were supposed to throw out oil at the end of day; but many enterprising people would secretly collect the used oils in the middle of the night, then clean out the used oil particles using unhealthy chemicals, then resell the clean-looking oil to restaurants and in bottles for consumers. I literally would see these small tanker trucks driving around my Beijing neighborhood around midnight. "May you live in interesting times"...

When I cut out seed oils and went on a high saturated fat keto diet, my C-reactive protein level tripled and LDL shot through the roof. Fortunately I was only on it for a short time bc it's a miserable way to eat and not sustainable. Additionally, healthy cell membranes and mitochondrial function absolutely require unoxidized Linoleic Acid. Too much saturated fat incorporated into membranes make them stiff. You'll never hear me advocating against unoxidized PUFAs or MUFAs.

IMO the main issue is that it's a lot more entertaining and engaging (and honestly potentially easier for people to comply with) to tell people that certain foods MUST be avoided at all costs, then to tell them a nuanced idea that some broad categories of food should be eaten frequently and some foods should be eaten less frequently. The latter is a pretty healthy way of eating but less attention-grabbing
Boring truth: seed oils are fine, but you probably eat too much of them.
Salacious lie: seed oils burned our crops, poisoned our water supply, and spread a plague unto our housed!

I saw one particular video where he was doing it screaming like a lunatic and you clearly see a lady in the background wanting to go down the isle look scared and take off in the other direction.
@@Ryan_DeWitt His ranting in stores (especially shirtless) bug me bad.
Impressive! Thank you so much! Dr. Layne Norton,
You say that seed oils are only an issue when they are heated and cooled many times. Isnt that exactly how they are made?
Ikr
lol, I was just saying this when I read this comment
Exactly, if Layne is unaware of this fact , should tell you something
According to the internet they're either cold pressed, hot pressed, or solvent extracted. two of these methods don't result in high heats and none of them result in heating and cooling them MANY times. Plus he says even then there's not great evidence to support it
Layne is conveniently overlooking this point
I love how in the study used at 6:33 saturated fat is lumped in with trans fat like theyre similar at all
Yep, and thats why I dont trust these test studies. Your own body will tell you all you need to know. Eat foods that keep you satiated for longer, so that you energy intake will never get high enough to make you obese. In my case, there is only long chain saturated fat that makes me full and keeps my mind focused and in good health.
Sesame seed oil is the oldest cooking seed oil and goes back 10,000 years and it reduces inflammation in multiple studies. Most seed oils are over processed and trash but some are beneficial. I still rather have olive oil and grass fed butter/ghee. They also go back 10,000 years
"Grass fed butter" is the grass somehow chemically altering the saturated fats?
@@Voidapparate The cow the milk or cream was from ate grass is what hes saying
@@forward2000 Yeah but how would grass fed butter be chemically different than grain fed butter?
@@Voidapparategrass fed beef has a better proportion of omega 6 vs omega 3
@@HeraldofNurgle7 We're specifically talking about butter.
I am concerned about the trace amounts of hexane in processed seed oils. Hexane is an industrial solvent and even trace amounts should not be tolerated. Double-blind trials do not help detect problems which occur when you eat trace amounts of toxins for decades. I believe that moderate amounts of ghee and olive oil are much better options.
Exactly, I don't believe any of those So called clinical trials. None of them are conducted for decades. Most of them are done for months. You can be totally fine with KFC and McDonald's for several months. 😂 It is so simple. But people don't get it. You shouldn't wait for clinical trial to stop eating refined oil and sugar. There are better options anyway.
I am totally on board to not get dragged from biased health influencer and “studies “ that support their theories. I can feel your frustration. As Italian I still don’t use any seed oil, but it’s just culture I guess. Back home we fry (very little) in lard or peanut oil (last 20 years) and we use mostly extra virgin olive for everything else, little butter here and there. Along with eating a veggies, fruit and grains rich whole foods omnivore diet . I moved to Canada in my 30’s and the shock I got from seeing how much more ill people compare to Italy it’s impossible to erase. Will never abandon my Mediterranean lifestyle ❤😂
Like bad fashion, nutri myths also go around in cycles. In the 90s it was anti vegetable oils, now seed oils.
Ironically, YOUR BEST video to date. I have a UCLA Bio Degree and sometimes leave idiotic messages just to amuse myself. The Paul Salad*ino impersonation should get you an Emmy. Great info buddy.

Nice one - thanks for crunching through the papers so that I don’t have to… PS - I hope this one does really well so that you can afford a bigger T-shirt 😉💪🏻
Yes, be lazy and simply take his word for it.
@zerrodefex Thanks for the kindly comment - you may notice he lists his references, so that I do not have to take HIS word for it... twit.
If he truly 'crunched through the papers' he would see that study after study debunks his views on saturated fat. There is no correlation between saturated fat and heart disease or cardiac events. This has been born out by multiple studies and evaluation and debunking of studies that said there was a causation. Layne is not the 'be all, end all' of nutritional science. There are just as many qualified individuals in his field who are saying the exact opposite of Layne regarding seed oils and saturated fat. And they have the studies to back up their information as well. We must discern and sift, compare and contrast.
@@guibox3 I have atherosclerosis, the conflicting research does my head in 🤯 but I do appreciate that he gives links to his sources. I would like to hear what is @biolayne1 opinion on the work of Prof Tim Noakes et al.
@@guibox3 can you simply post the studies instead of posting a long comment
Great video. But speaking on the saturated fat portion of this video, the Journal of American College of Cardiology wrote in a study in August of 2020: “Several foods relatively rich in SFAs, such as whole-fat dairy, dark chocolate, and unprocessed meat, are not associated with increased CVD or diabetes risk. There is no robust evidence that current population-wide arbitrary upper limits on saturated fat consumption in the United States will prevent CVD or reduce mortality.” Thoughts?
NutritionMadeSimple, an MD and PhD in nutrition science, discusses saturated fats in detail and the range of good to bad sat fats specifically chocolate, dairy all the way to beef fat here: ruclips.net/video/mBFe1QattAU/видео.html
Yes. So many people on here saying, 'Yeah, this 'seed oil is bad' is just nonsense', will readily believe that 'saturated fat is bad for you' when study after study shows no correlation between saturated fat and heart disease. Apparently to Layne and other gullible people, canola oil is healthier for you than saturated fat found naturally in our meat and foods. Sounds like they are still brainwashed to me. The last 40 years has shown that this advice has made us sicker and fatter. Not sure why Layne seems to think this is scientifically sound nutritional advice.
Quite simple. Foods are different, in part because of the varying fatty acid composition in those foods, and the other chemicals they contain that interact with them. Try looking up the food matrix effect.
@@anglicantian Quite simple. Science of nutrition is bs

Thank you for sharing your take on the seed oils. I am sure you are qualified and spent a lot of time researching before
Excellent video thank you for being evidence based. Couldn’t agree more. Noticed these same sorts of obnoxious unsubstantiated claims on social media. Keep it up Layne.
Seed oils are used in everything which causes everything to be entirely way more dense. You also brought up seed oils are bad in excess but they are used in absolutely everything when you go out to eat, or get snacks
They aren't used in everything, not even close. Yes, they are used in a lot of restaurant food, but I think that's part of the point; should we be going out to eat all the time? (no)
Any prepared food item basically yeah. Mayonnaise, FIRST ingredient is a seed oil. Coffee creamers too.
@@strategicsage7694 probably 90 percent of processed foods contain seed oils unfortunately
If you are eating good whole foods most of the time within your caloric needs, then it will make no difference. You can't eat donuts and fries all day and say they are in "everything".
@@turntablesrockmyworld9315 i think you missed the point lol.
Layne, I go back and forth on this. You have to take a better look at these studies to measure exactly how much PUFA people were consuming in these randomized trials and match it up to the real world consumption. Yes, energy toxicity agreed, but is there more to it? Remember the TRANS FAT was undeniably toxic and atherogenic (finally banned by USDA Jan 2020). Wouldn't it just make better sense to eat the foods that these oils come from rather than extracting the oils through a scrubbing process involving chemical and heat denaturants which can oxidize the myriad of unsaturated bonds in the fatty acid molecule (with a side product of toxic aldehydes)? In essence, isn't that what was done intentionally by hydrogenating the TRANS FAT? Manufacturers know there is truth to what I'm saying, otherwise, why would they be going to lengths to sell the "expeller pressed" oils if science was on their side with previous methods? The verdict to me is still hanging. I would counsel people to as much as possible stick to a whole foods diet, avoiding overly processed foods.
You discuss replacing saturated fats with Seed Oil, but I think most (looking to be healthy) would be more interested in the advantages of replacing Seed Oils with Olive , Avocado oils (higher in Mono than Poly or Sat fats) and what control studies show are the advantages of that substitution.
Thanks for all you do !!!
This
Studies suggest polyunsaturated fat might be even better than monounsaturated fat regarding the prevention of CVD. Regarding inflammation there is no difference or at least the studies didn’t seem to find any. I use Olive oil mainly because I love the tase but I don’t mind seed oils either.
There are not very many studies on monounsaturated fats for some reason. Probably just lack of interest.
I personally want to keep my saturated fat intake as low as possible while keeping my omega 3,6,9 as high as possible so I can get the most nutrients out of the calories from the fat. Olive oil is a good option but I also like my canola oil
I did that and biggest thing I've noticed is that I've gone the entire year without getting sunburned. Polyunsaturated acids oxidize more easily that saturated or mono when exposed to UV and that oxidation of the fatty acids in your skin is what causes sunburn (and possibly cancer.)
Oh you’ve done it now. You’ve angered the plant hating “carnivores”
I have a feeling they are always angry😂.
I’m a carnivore and I am no fan of plants or seed oils for that matter, but I liked this video. Ive never found the arguments against seed oils very compelling, but I stay away from them anyway because they were part of the problem back in my overweight days. I eat the way I eat because I can adhere to it and thus keep the weight off and progress toward my fitness goals.
You forgot to hyphenate "plant hating." It should be "plant-hating."
@@rontiemens2553Same here. I don't add oils to foods either but neither do I add butter or other animal fats. I only eat fat that naturally comes with meat and eggs
Layne norton is a crash dummy advocating eating hydrogenated seed oils, i run laps around you mfs eating canola oil
The thing that must be "addressed" is the novelty of seed oils in the human history.
There's no way that it doesn't impact negatively the body.
When I eat seed oils, my gut inflammation kicks into full gear and I’m miserable. When I cook things in beef tallow, butter, EVOO, I feel amazing. Been living with Crohn’s for about a decade now and eliminating carbs and seed oils from my diet has helped me stop taking weekly injections. Haven’t felt this good in years and I finally have my life back just by changing my diet. In the process I’ve lost a lot of weight too. Doctor Robert Lustig, right here on RUclips, has a lot of insightful information about how unsaturated fats chemically change when under extreme heat and pressure alone, which is what every seed oil needs to go through to become “edible”. He breaks down the exact science of why it occurs and how it negatively affects your body. Labeling natural saturated fats as unhealthy, the fat that oxidizes the slowest by far, has been one of the biggest metabolic mistakes doctors around the world have pushed.
This is exactly why I’m watching this video. I recently started eating seed oils again and I noticed I feel so heavy and gross after. I wonder why it affects some people like that if the studies don’t show it having a negative effect. I didn’t know the food had seed oils in it but after feeling crappy I asked and it turns out they cook with seed oils.
Is there a chance that you were eating less calories when you swapped seed oils and carbs for saturated fat and therefore you lowered inflammation because losing fat does that?
@@JoshYarlett I did not alter how much I was eating, just what I was eating. It’s incredible how bad I feel after eating things cooked in seed oils. It’s like going from 0 to 100. My stomach begins to cramp the next day, my heartburn instantly comes back, and my 💩 is loose and/or diarrhea - which is a clear sign of intestinal inflammation
@@rg975 I honestly don’t know what that could be but I’m not an expert. I guess seed oils just don’t agree with your system in which case then yeah probably limit them

Total calories consumed per capita in Japan have DECREASED since the 1960's. Sugar per capita has DECREASED in Japan since the mid 80's. Diabetes, obesity and CVD have all skyrocketed in that time, so what could it be? Use of seed oils has skyrocket in that time from average 90 cals per person per day in the 1960's to 400 calories today. Today in Japan the average diet is 1,850 calories down from 2,837 in the 1940's so they are now getting 22% of calories from seed oils compared to 3% in the 1940s. This is DAMNING.
Also, you are switching subject by pivoting away from seed oils to saturated fat. Stick to the topic, seed oil use has skyrocket in EVERY developed country where CVD/diabetes and cancer has increased dramatically.
Now look at the US. Sugar per capita has DECREASED in the last 30 years. Obesity and seed oils have continued to skyrocket.
Now look at Australia, sugar has been DECREASING since the 1960s but obesity and seed oil use has been skyrocketing there.
Now look at China, sugar hasn't moved much at all in the past 100 years but the entire population switched from using animal fats to seed oils to cook three meals a day (virtually 100% switched from animal fats to seed oils)....and disease and obesity has skyrocketed there.
Literally EVERYWHERE you look you see skyrocketing disease and obesity when use of seed oils increases, usually in tandem with declining animal fats.
See how much you have to type, creating all of these copes, instead of posting EVIDENCE? What do randomized control trials show? They show you people are crying over nothing. The same people crying about seed oils, are fine with gallons of animal fats a day.
@@vashlash6870 so it has to be a lab in order to be proven to you? just look at how Americans ate in the 1960's and how skinny they were, compared to Americans in the 80's. Layne wants to blame the excess calories, and people becoming more sedentary (which isn't true), when there's been a massive switch in the ingredients used, not the caloric intake. In the Minnesota starvation experiment the subjects were started at 3,200 calories, which was considered the average caloric intake for a 150lb man, then they slowly reduced it over time to 1,500 and they became emaciated and their organs shrank. Point being, the average intake was HIGHER in the 1960's than todays 2,000 calorie diet. Just go watch a video on how seed oils are concentrated and then decolorized and de-scented, tell me that's natural. You don't think Layne was probably paid off by the seed oil companies to make this sort of video? You really think he's putting out this sort of video just to 'disprove' the carnivore camp?
your assumptions are exactly opposite, asians are eating more saturated fat today than ever, their previous diet had less animal products and has increased in animal products since the 1960s.
Care to add reference to measurement of caloric intake in japan over a period of time?
@@mattvdhyou clearly don't understand how, or why, science works. Appeal to naturalism; check. Baseless accusations of corruption and collusion with "Big Seed Oil"; check. All to protect your cozy narratives.

Don’t expect Layne to understand it. Layne was bullied as a kid, it clearly shows in the use of profanity and his childish memes.
As a biochemist who had to study metabolism and investigated the refining methods of seed oils to educate myself on the matter, I can confirm that these anti-science conspiracy theories in the comment section are worse for my health than the jug of canola oil I sear all my meat and vegetables in.

When you have opened your mouth my perception quickly changed as you are anything but!
Kudos!
Commenting & liking to boost your channel!
After finishing this video I've realized my comment under the pinned one was partially superfluous. And there are some things I'd like to add:
I like your humor in the middle. In some cases you can only do epidemiology, in vitro and in vivo animal model studies. Unless your last name is Mengele or your team have the number 731 attached to it. (Or their less talked about Antant counterparts...)
You have to be happy if you make THOSE kinds of people angry.
What I missed in this video:
You should have mentioned that all seeds and seed oils aren't created equal. Far from it!
For example Rapeseed and Sunflower vs. Palm and Coconut oils are night and day. And especially true for palm oil as it isn't only bad for your body for multiple reasons but also terrible for the environment. Tons of species go extinct due to the plantations including one of the cutest elephant species of all. And they are objectively feeling, intelligent, sentient and most likely sapient brings with very human like but probably even more complex language systems. Coupled with a wide range of cultures, customs, celebrations and ceremonies. Maybe even religions as the ancient thought they had (written in classical Greek, Egyptian and Roman literature... Sun God worship centered religions according to their beliefs).
And they are the only non human animal sibling known for us that gives their members their personal given names according to human logic, contrasted to other, balls different but not necessarily less complex naming customs and traditions of cetacean and bird and other non human ape species. As far as we know it today off course, but we are in the very beginning of non human language and culture research.
Probably you have videos on the effects of different kinds of seed oils on human health but a couple sentences long mention here is needed IMO. Most people haven't watched all your videos.
I hope you don't mind this constructive criticism from my part. I'm sure you wouldn't add you came across more intelligent than that.
I only edited this comment for correcting some swypoes for clarity.
Why are there more quality studies on polyunsaturated fats than of monounsaturated fats?
The issues with seed oils isn’t just about weight, it’s about overall health.
Yeah. I'm trying to avoid tings that are overly processed. I learned I have a lot of inflammation and most likely an autoimmune disorder by now and I don't eat sugar and fried foods,. But seed oil is in everything - every other health food even. I was informed to avoid processed foods.
@@catherinewylie6959just because something is processed does not mean it’s inherently bad.
@@user-rf2fv6tf1p Yes. I understand that. I mean in general - the real crap stuff out there . As well, a lot of health foods are hard on my stomach - like those Macro bars. I had a stomach infection and my immune system over responded to it, and I can't eat a lot of things now even months later.

Love the mutual fund analogy. Very helpful info as always
This is such a perfect summary
This guy and Nutrition Made Simple are telling the truth!
Yes. Nutrionmadesimple is awesome. He communicates nuances well too. He name checked Layne also.
Travesty of media why Saladino’s carnivore diet goes viral and quality science channels like these guys don’t as much.
I appreciate the break down with emphasis on randomized clinical control trials. I’m curious how the comparison looks with omega 3 rich cooking oils like Avocado or macadamia oil vs PUFA or Saturated fats. The latter 2 are not the only cooking oil options.
Yeah. It’s good to know it’s not the French fries giving me heart disease and that they’re actually healthy.
Yeah I'm disappointed that he didn't go over the full spectrum of oils. The data is clear that a magnetic 3, 7, and 9 do benefit health far beyond other oils. However, even too much omega-3 can begin to be detrimental.
@shiftgood It’s the fact you’re eating an unreasonable amount of French fries, not the fries themselves. But of course let’s scapegoat instead of looking at ourselves. That’s easier.
I've dived into a few studies, mainly meta-analyses, that I've seen referenced in videos like this which take the anti-saturated fat (mainstream) PoV. Somehow they never quite check out. For example, you see studies which indicated lower cardiovascular events with lower saturated fat, BUT in the fine print you discover that all-cause mortality was not improved. And for example, in the "sat fat increases lung cancer" study linked in this video description, the fine print showed that sat fat consumers who never smoked did not have have statistically significant increase in lung cancer. Every single study I've looked at has major holes in it like that. So I'll stay open and keep researching. But I'm not convinced of the mainstream PoV that completely novel industrialised oils are magically better for us than ancestral diets. There is a LOT of money from industry pushing this, from both big agra and pharma, so the burden of proof rests with them and I'm not convinced it's there.
@@RaveyDaveyStrong words. Why does Big Processed Plant Foods conduct many times the studies than the govt? To lose money? How long does it take to get a heart attack from a bad diet?
@@RaveyDavey that's not what is showing up in these studies. What is showing up is increase in cv events but decrease in cancer. Eat seed oils get cancer, eat sat fats get CVD. That's how total mortality seems to even out. However the main confounding factor is that sat fats have been demonised for 70 years so most people who eat more of them are lackadaisical about their other health habits, such as exercise, alcohol, sleep patterns etc.
Seems Layne is the type of guy that only reads the abstract and thinks he is the smartest guy in the room.
Was checking the studies he referenced and noticed questionable research methods relative to Layne’s claims.
For example, in “Overeating Saturated Fat Promotes Fatty Liver and Ceramides Compared With Polyunsaturated Fat: A Randomized Trial”, they used palm oil (50% saturated) as saturated fat and sunflower oil as PUFA, both are highly industrially processed vegetable oil that gives no context as to the comparison between natural saturated fat in animals vs processed seed oil.
Nobody these days eats an 'ancestral diet'. That's not an option that's even on the table, literally.
@@strategicsage7694 i didn't say that they did. I have no idea what your point is intended to be. Good luck chasing that ancestral diet though
Thank you Dr. Norton. What are your thoughts on the Minnesota Coronary Experiment and the LA Veterans Administration Study? Seems the vegetable oil consumption is correlated with shorter lifespan. Thank you.
Thanks Layne. You have open my eyes to look at this with a more open mind. My take from you in make heathy choice’s all in moderation. Thank you.
He doesn't give you heathy choices.
Excellent appraisal of the poly vs saturated fat evidence. Everything in moderation besides smoking.
And trans fats which are artificial
No mention of omega-6 to Omega-3. No mention of seed oils originally being used for industrial machines. No mention of how diabetes was not as prominent before seed oils before the 1950s. The nuance nutrition science RUclipsrs will have plenty to discuss after this video. However this video was a good move for the algorithm to shake things up.
All of which is rhetoric like story telling. Rational people don't care about that. They care about outcome data. So what actually happens.
I have a sincere question. Are the health benefits of carnivore diet coming STRICTLY from eliminating potential triggers? Why are people experiencing life changing symptom relief (gut issues, mental clariry, joint pain, skin health, and increased energy)? If elimination diet is so powerful and healing, why is it that only carnivore diet is known to be effective? I understand that studies are important, but I have witnessed people and read thousands of anecdotal storires of the benefits and i am very confused. Also, do you think that the USDA guideline on the ratio of macronutrients are health promoting and that as long as we eat less calories then we would be healthy?
There are no benefits of the carnivore diet unless you are in the micro percentage of people with crazy food allergies.
Probably cause proccessed foods are bad, and if its just meat that isn't heavily processed yes they will be healthier than those who do eat crappy processed meats but those who are whole food plant based are healthier than non processed meat eaters🤷♀️...
Nothing but love from me for this video.
Wow. This is exactly what my gut feeling has been telling me my entire life.
Thanks for the great information. 👍🏻❤️
Thanks for the clarity and logic.
How long has humanity been consuming fried food? And how much fried food do we consume? Layne, I'm not pointing the finger at you, personally, but science has no excuse whatsoever for dropping this massive ball. There should be zero ambiguity over the use of reheated oils for frying. Zero. It's an effing embarassment.
With 'that' image next to his name, it is kind of hard to take him seriously. There is a difference between looking good and health. Muscle heads tend to die early, right?
No hate! Love the clear communication. Thx for cutting the crap. It’s scary when Drs of any type (Gundry, Saladino, Berg) become money hungry influencers. Makes me sick.

This guy does nothing more in these videos than parrot "THE SCIENCE" with an arrogant, superior, know it all, demeanor which in the end may or may not be accurate.
The issue with these seed oils debunking video is they approach it in narrow one sided view (same with the Nutrition Made Simple video). This video doesn't even talk about the subject in question, but wholly about why saturated fat and too much calories are bad.
Not me pouring extra sesame seed oil in my stir fry tonight
Okay... agreed! Too many "calories" ... BUT, for my husband and I, as we are fast approaching our 7th decade of life ... we have noticed increased soy, hydrolyzed and partially hydrolyzed palm oils, modified corn starch, corn syrups, and maltodexrin, (among other useless ingredients) added to our "foods" today, along with "natural flavors" added to Earl Gray teas, and more, which INCREASE calories, compared to what we consumed 50 years ago! This is one Dr. Lustig revelation with which we simply must agree, as we have witnessed this ourselves!
Dope video! Love the scientific references! Subscribed :)
Keeping it real and educating. Calling out the cherry-picking fear creators haunting this industry. Using analogies to help understand tactics.
Imagine describing people who advocate a healthy and natural diet that has been followed by humans since the beginning of time as “haunting the industry”, because they don’t consume bottles of Wesson “vegetable oil“
Yeah a random guy who might make 40k in RUclips advertising in 3 years is who we have to worry about. Not the food industry that puts seed oils on 95% of all US products. This all started in the 1900s when they realized they can press cotton seed and make oil. This was at industrial factories and moved to food. It’s a money game. Human beings aren’t supposed to eat oils from seeds. It’s not healthy. You’re being played like a fiddle. A random RUclips doc isn’t who you should be scared of 😂😂😂😂
@@chevelleman88it’s wild and this guy won’t even reply to your comment because he’s in an echo chamber
It's not just influencers. I'm quite literally a nobody on youtube and I can vouch for the effectiveness of removing seed oils from diet.
I'm quite content with my personal knowledge and will simply wait for the science to catch up with my experience. I know I'm not alone, but even if I was: I'd be totally fine with that.
Substitute "seed oil" for toilet paper.
I'm pretty sure we could eat toilet paper, and it would have a net neutral impact on our physiology. Mix it into our mashed potatoes and soups.
Let's say everyone starts doing this, And it starts comprising 30% of human intake. Intake which COULD be occupied with nutrient dense, protein rich food.
Then one day, after you realize while you feel full after you eat, you're starting to develope deficiencies. Skin starts breaking out. You're not poopin' right, and your breath smells like Charmin.
You take to the Internet to tell everyone you're DONE eating toilet paper! It's not natural, and by replacing it with whole foods, your symptoms have improved.
Suddenly, pro-toliet paper influencers start attacking you as a "grifter" for advocating what can only be described as more species appropriate diet.
That's where we are.
At BEST seed oils are nutrient filler, even by Layne's own argument. At worst we're consuming excess amounts of linoleic acid and Omega 6s, not to mention an overabundance of calories in the way of FAT.
I'd rather eat toilet paper.
How about we all just eat less and move more?
Because that's a gross over simplification of the obesity epidemic
@@DarkAbyss9Is it though?
@greul_vietii yes
This over simplification is like telling someone who is depressed to just be happy. Shit doesn't work like that and I bet those who spew this "eat less , move more" are the ones who have never had issues with weight in their entire lives.
Go look at someone like Dr Nadolsky who is an obesity specialist, you may learn something
To be fair there is also issues of satiation and satiety.
I've seen in my country how the food environment got worse and worse.
In the current food environment you have either to control yourself (I wouldn't and wasn't able to do that - but some are less effected by it) or you have to change your diet (I adapted to pretty much the diet my grandparents ate and grew up in - now I need no control and can stuff myself until I'm full).
And in terms of food volume I eat a lot more than I ate when I had trouble controlling my weight and were hungry constantly.
My grandparents grew up in a country where they didn't have to control their food intake or change their diet.
While every individual can still make a change for their health, the reason it spiraled out of control on a societal level is a environmental issue in that society.
@@DarkAbyss9
A similar analogy wouldn’t be “be less depressed”.
It would be “go out more”.
I eat less you and move more you lose weight.
If you have insulin problems that doesn’t stop cico.
Just take your meds and start exercising.
Thanks Layne for this clarification, I have been confused about this topic for a while but you nailed it and brought it into practice.
Dr. Norton went HARD on this one!
Hey Layne, thanks for posting this video - I was hoping you would do one on seed oils. My further request would be, could you take a look at Dr. Cate Shanahan's videos, and give your take on the mechanisms she cites as to why/how seed oils are causing problems in our diet? Again, appreciate your take on these things, as it is very difficult for those of us not educated in this area to figure out who is right, or find a unifying theory that explains everything.
If the issue was just calories in, calories out, people would not have the issues losing weight that they do. The mechanisms and underlying metabolic interference from these novel foods are being underplayed by the research.
Dr Layne, I appreciate that you are backing your opinion up with research. But: What you need to understand is that the scientific communities politization has rendered studies supporting controversial topics dubious at best. Are you looking at whose funding this research? Are you considering the replicability crisis? Are you considering the fake paper crisis?
I'm sorry but "peer reviewed study" doesn't mean much anymore, until the problems in academia have been fixed.
the idea america has this humongous obesity crisis, and that it would be because of "surplus of calories", is ridiculous. its a big food lie to have people not question the quality, but focus on the quantity.
i would bet if we banned seed oils from our food supply, the 90% of the obesity epidemic would resolve over 4-5 years.
@@tallesttreeintheforest it would take a little more than just the seed oils, need to get rid of the endocrine disruptors too. No roundup on crops, no plastic food packaging, no teflon pans. No articifial dyes or flavors. No flouride in the water.
But if we did all that, obsity would resolve in like a year, and Big Pharma would go bankrupt.
3:20 is exactly why seed oils are attacked.
You’re playing reasonable fencesitter. It’s gonna get hate from everyone. You’re not wrong but I also think you’re being kinda lame.
The doctors who thought eggs gave everyone heart attacks were real confident about it too.
Sorry you fell for that narrative that someone started. Just like the "it was global cooling!"
Hi, I was in nutrition science decades ago and in general this was not the consensus in research but more in the headlines. There was also not a clear understanding of the role of dietary cholesterol and cholesterol in the body which made it valid for the time as a precaution. It is still also valid for those with hypocholesterolemia and those that have intake patterns outside of a normal dietary range.
I eat 8 eggs a day and I've never been healthier in my life
@@Ryan_Decker Response to dietary cholesterol is individually varied. Overall it is not good but, as for someone like my uncle, ingesting approx. 1600 mg. of cholesterol from eggs like you do can be life threatening for him.
@@Ryan_Deckeri eat 8 eggs a day and never had a heart attack. checkmate vegans
i think the most important thing to remember about the seed oil debate -- and almost any debate is that just because a study shows that majority people do not get more sick from seed oils, there are some outliers (which could end up being YOU) that aren't considered and are drowned out in the average data that skews towards seed oils being healthy. Not every single person in a singular study benefited from seed oils and some did get sick. So just take into account how you feel after eating certain foods and listen to your own body and take studies into consideration but not as instruction manuals.
LETSSS GOOOOOO been waiting for this one
Great video.
What type of cooking fats do you use at home?
Ok, and do we have zero issues with the process those refined oils are produced? I find them bad by nature.
I'd say it depends on what you mean by "bad". Bad for you? Well, as stated in the video: not necessarily, saturated fat seems to be more of an issue. Bad for environment, pollution etc? Perhaps, but that's not something that the video addresses. Here we're purely looking at the health impacts of them.
@@kkrizzz I speak about REFINED oils. If you have to use chemicals to make a product stable, it doesn't seem right to me. We can take jus Hexane alone. I don't think this experiment is going to be beneficial in a long term. And it is very hard to define issues with saturated fats as the refined oils are everywhere, so it is not easy to do a proper RCT research in a long run. Epidemiology is better than nothing but far from conclusive.
Yes the process of making these oils is disgusting. I will not eat them anymore xxx
@@ziilux84They use hexane to extract the fats, and recover the hexane by boiling it off.
@@Arbitrary_Moniker high heat is definitely beneficial to the end product, right?
Is there any truth to omega 3 : omega 6 ratios? I never hear you talk about omega 3 supplementation. Is it worth it? I remember it being big in the paleo community many years ago.
It’s only true within the context of a diet that does not supply arachidonic acid and DHA. In other words, if your diet counts on converting the precursors to the active forms, then the ratio matters, because that dictates enzymatic competition. However, if you consume eggs, liver, and fatty fish fairly regularly, then the ratio is of no concern.
No. Paleo is a joke, as in, what time in the Paleo era, and where.
@@tresero2862 the question was does omega 3:6 ratios matter. You said no because paleo is a joke. How does the status of paleo (weather it is a joke or not) affect if omega 3:6 ratio matter?
I remember it being big in the paleo community many years ago.

I've been concerned about the inflammatory effects of seed/vegetable oils for a long time. Long before it was a rash on RUclips.
That said, I appreciate your breakdown. My bias will continue to favor other cooking oils (and butter), and obviously this doesn't mean I can go out and eat tons of chips.
honestly… my new favorite video
Number one FTA!
You're a rare voice of reason amidst all the confusion and fear mongering Layne. Keep doing what you're doing, it's helpful.
Not really, he's prone to calling many other people phonies and being on his high horse. Look how he used to treat Thomas Delauer and the amount of time it took for them to collab because Layne refused to think of him as someone trying to seriously learn more. Layne was clearly the prideful one in that scenario.
Layne definitely knows a lot and is a voice to listen to in order to learn, but he's not the arbiter of truth. I think it's also valid to be skeptical of anyone who claims that all they do is "data over dogma".
It's from another field, but there's a linguist and ancient historian scholar called Dan McLellan, who claims to be the opposite of dogmatic, yet when you see his content up close, his "data" tends to line up with his political opinions and biases that he refuses to acknowledge. I think Layne is better than that, but *nobody* is free from bias.
@@carlosjosejimenezbermudez9255 No one person is the arbiter of truth and Layne has definitely been overly combative in the past, I agree. Still, his way of cutting through the social media BS and food disorder gurus that are running rampant right now is a something that is sorely needed. Anyone who has clicked on a few diet videos is getting bombarded with content that makes you afraid of eating pretty much anything at all, regardless of whether or not it has a detrimental effect on you. The hyper-fixation on out-of-context mechanisms on a cellular level is dangerous and Layne's stock analogy is spot on.
@@TC-by3ilI agree - many of the spread information is dangerous. A healthy diet and lifestyle is the key to disease prevention. And it is great when people are willing to invest their time and resources, researching what to do and eat best and unfortunately end up on a video of one of these fearmongering individuals that spread misinformation.
I mean people in the comments are writing that the stoped prescription medications and are proud of rejecting their advice on medication and diet, believing the diet will fix all their medical problems.
This is madness, and there needs to be some reasonable creators in the area of nutrition and fittness on RUclips.
It is seed oil supporters that are fear mongering people.
Science is flawed, despite being helpful. Ultimately, I like to focus on personal experience. When I follow Dr Saladino’s animal based diet, the gut problems (diarrhoea) and psoriatic arthritis that I have experienced for decades completely goes away. I have been following Dr Saladino‘s diet for two years now, and it has transformed my life. I am a medical doctor, and medical science with its RCTs simply provided me one antiarthritic drug after another, which would provide relief for some months to years before eventually fading away. I am now resistant to just about every drug on the market, but there is no sign of Dr Saladino‘s diet stopping working for me. One personal observation I have made about the mechanism of action is that when my gut health improves my arthritis likewise improves, and my gut health is so much better on Dr Saladino‘s diet. I’m not clear which part of the diet helps, but it is without question that it works for me.
Layne. Thank you so much.
@biolayne
Thanks again for a great video!
Is there a difference between "refined" oil and the virgin/extra virgin oils?
yes, would suggest googling it- but generally any of the oils that will come virgin/extra virgin exist without extreme processing to acquire them. ex. squeezing olives gets you olive oil thats ready to eat vs. a canola that requires heating/pressure/bleaching/deodorant/chemical additives/another 10 steps to make an oil edible
@@Khanfuzed1 I wonder though what are the benefits of virgin canola oil as I saw some "organic virgin canola oils". I wonder
@@hagaigat there is no such thing. If a label says that it may be a blend of olive/canola.
if that is the case you are getting bottom shelf versions of both to make a cheap blended product
@@Khanfuzed1 thanks
we cover this in our episode with Dr.Kirten: ruclips.net/video/p3Zc_XZ6EGQ/видео.htmlsi=jycef97L9YkGLE6c
side effects of seed oils include this video :)
Paul Saladino has responded to this video with facts and data with a THOROUGH deep dive in the meta-analysis Layne uses here. I have to say it again: Layne is in over his head here and DOES NOT understand the fundamental argument.
Layne's breakdown and research is undergrad level. Paul's breakout is a true deep dive into the component case studies used in the meta-analysis.
If you haven't listened to Paul's evaluation of the bio-mechanics of what's happening here, you, like Layne, are wading in the kiddie pool.
This goes so much deeper than what's being presented here.
Layne:
Sir, if you ever want to be taken seriously in this space, you will need to put yourself out there and debate Saladino. You're still playing checkers and Paul has you mated in 3 moves. I think you're a smart enough guy to understand and acknowledge your mistake.
Now.. whether you have the ability to swallow your pride and publicly admit it, remains to be seen. You can very easily repair your credibility with a smidge of humility....
Everyone will be better for it. Good luck to you.
What a beta comment, with literally no evidence to back it up just referring to some dude
@@Littlegoblinfatface why don't you watch the video he's referencing bozo
@@Littlegoblinfatface "beta comment"? yikes. peak cringe. Because commenting on a RUclips video is a good marker for masculinity right?
Btw: Paul ain't just "some dude" and if you haven't heard of him you're nobody I really care about in this argument. Now go sweep a motorpool or something...
Saladino denies LDL causes ASCVD. He rejects science.
The video literally confirms to stay away from the oils and to be conscious of the food you consume.
Tdlr: Biolayne is paid by big ag industrial complex
What a great video! You deep dive in great science and more people should listen to your insights
