In the end, everyone must follow their own personal requirements. You may have a sensitivity that I may not have or a lifestyle that better supports one diet over another.
How were the seed oils prepared and served? Were they in pills and not cooked? If so, then they were not served in the manner in which they cause the most damage. In other words, were they fried? If not, then nothing in this study means anything.
Yep, this is the problem: Layne will say it's nitpicking to ask for an RCT with oxidized omega-6 vs. fresh; I think it would be unethical. I understand nitpicking can be annoying, but it is literally how science improves incrementally.

Actually it doesn't matter :-) if you want more context you can search on RUclips for info.
Not everyone deep fries their oil, bro. Heating it for cooking to saute something does not show to increase oxidized lipids or acids by much. It's doing it over hours and hours.
@nick7072 I agree with you. In fact I would find it odd if people treated their oils at home the way a restaurant treats them: heating to high temps and reheating for days sometimes. That would be weird. But every restaurant does this. Everyone of them. So, there's ground for nuance here. The idea that nuance is nitpicking is anti scientific in my opinion.
Great vid as usual Just want to point out in case anyone else is confused; Layne mistakenly said "alpha linoleic acid" a couple times in the first half of this video. "Alpha linoleic acid" does not exist, and I'm sure he meant "linoleic acid", which is the predominant Omega-6 PUFA found in seed oils. He even correctly says "linoleic acid" at a later point in this video. This is just a slip of the tongue, accidentally combining "linoleic acid" with "alpha linolenic acid", which is an Omega-3 PUFA found in some plant foods, including canola oil ;)
Seed Oils are like firefighters. They are at the scene of the fire but not the problem. The problem is that they are often found In hyperpalatable foods. Years ago my brother and I interviewed Stephen Phinney, the keto king that most people based their research in keto on. He told us seed oils were no different than any other fat and not an issue on keto. I thought he was mistaken and just didn’t know the “new” info, but now I realize there has been a ton of information on them for years. I have no desire or reason to ever consume them however in talking to really smart people like Alan Flanagan, and Layne, I don’t think we need to worry about them if they are on your steak or in your salad. Worry about them in Oreos.
@@paulc5389 > consuming seed oils is probably one of the highest causes of oxidation Proof? Studies don't show increased oxidation or inflammation in humans.
Gil Carvalho made a video covering numerous studies on seed oils, which showed basically the same thing, that they do not have a detrimental effect on one's health. I'm still not sold completely, but the more I hear things like your video I have to be willing to reconsider.
I think what people who are against the seed oils need to think about is 1) this study doesn't prove or even suggest that seed oils are "good" for you - it shows they have positive effects with 1 thing. 2) think about the _source_ of the omega 6's - it's not ONLY found in seeds or whatever other "bad" things, it can be found in what you deem to be healthy foods too. 3) remember the "real problem" with omega 6 is not the omega 6 itself but rather the ratio of omega 6 to omega 3 (maybe 9 too idk i'm not a scientist, just trying to remind people of what I've seen/heard to hopefully avoid foolish rage-fueled arguments) and that having a lower amount of 6 vs 3 is supposed to be "better"
The only problem is if omega3 is low and therefore o6/o3 ratio is high. High Omega6 to omega3 is positive if both are high. As such, ratios are useless. Stick to your quackery, but do it elsewhere. Watch Dr Bill Harris on omega 6 to 3 ratio, there's a nice clip with rhonda patrick.
@@ladagspa2008 it's not quackery bucko. I made no actual claims. as I said, I'm only trying to remind people that it's not necessarily that omega 6 is bad. people tend to change their arguments if something even slightly challenges them.

@@HAL-zx1bw the study your mentioning was a lipidomoics in vitro study. One cannot come to the conclusion that seed oils cause colorectal cancer from that study design in humans. Existing RCTs and meta-analysis of RCTs do not suggest an increase in cancer risk.
Think this hammers home the idea that we are simply consuming too many calories and the question is how do you effectively change the behavior of a population that is over-consuming. I would advocate banning advertising of foods that are high in calories and low in satiation. Empowering individuals to stick with their dieting without the constant temptation created by the billions spent to foods that should be rare treats.
Calories are not consumed. They are not a physical thing we consume. My goodness. It’s about what food is optimal for humans and how that food affects your hormones. This is why I now “consume” 4000 calories of animal foods and am leaner than when I couldn’t lose stubborn weight “consuming” 2000 calories. Let’s not even get into the mental health benefits.

Years ago when I was vegetarian in the majority of my fat came from nuts especially peanut butter Even though my diet wasn't exactly healthy I had endless energy , then in 2018 when I try to low-carb diet and I ate so much animal fat and yes I broke my vegetarianism The next year I felt like garbage like a big giant truck fell on top of me and I was suffering, I went to the doctor did blood work and my doctor said your liver enzymes are too damn high you need to bring them down,, she didn't tell me how to bring them down she just told me that's really really bad so years later here today My liver enzymes finally went down when I went back to eating more plant-based but a much more healthier balanced diet compared to what I was doing before but the low-carb diet was one of my biggest regrets I don't even know why I did it I was desperate I guess but I hated eating that way the whole time,, we do crazy shit when we're desperate
@DragoNate it doesn't matter because all low-carb diets are so miserable and disgusting and boring to me,, if it's true that you should enjoy the diet you're doing then low-carb diet was like being sodomized over and over and over again and I hate it every second of it I've done a lot of stupid things in my life but a low-carb diet was at the TOP OF MY LIST OF ONE OF THE STUPIDEST THINGS I'VE EVER DONE!!!
@@daysoftheboo You are so misinformed it is sad. Go look into professor Thomas Seyfried Boston College and you will realize that humans preferred state is probably ketosis. Not out of choice, but out of reality. Also go listen to Miki Ben Dor on why humans are hypercarnivores. You'll realize quite fast that humans are hunter gatherers. We ate mostly meat and fat from large ruminant animals. This is how humans have evolved and if you believe in evolution your cells want this not some carbs. Lastly, go listen to Bart Kay and you'll realize that Layne Norton hasn't got a clue what thermodynamics is. But, you do you.
@daysoftheboo that is your personal experience and it's true, some people feel terrible on low carb diets but many others feel great following a low carb/ketogenic diet. I've been eating this way for years and feel 1000x better eating low carb vs eating a high carb diet when I would have fluctuating energy levels, cravings, bloating and I didn't enjoy the food nearly as much as on my keto diet. To each their own, people should follow whatever works best for them.
I think most “anti seed oil” people argue that seed oils aren’t bad, but it’s how they’re made that makes them bad. Mechanical process for making seed oils is not considered bad, but the chemical process in which they are would be considered bad. Hexane, which is a hazardous gas, is used in the process and they say it’s evaporated out, but the FDA doesn’t actually test for hexane residue. Later in the process the oil is bleached to make it clear. So hexane and bleach are the big reasons anti seed oil people avoid seed oils.
No one is arguing that sunflower, corn, soybean etc seeds are bad for you. It’s why extra virgin olive oil is popular. It’s typically cold pressed rather than chemically made.
@@mricecream-clashofclansyeah we are. Any oil that's likely oxidated or highly prone to oxidation is bad for you. Even cold pressed olive oil will oxidate if it's sat in a bottle for ages after being pressed or if you cook with it.
It appears in the human randomised control trials that hexane residue is probably good for you. Also the bleaching. Maybe it’s the pufas that are so healthy, that they compensate double for the hexane and bleach. 🤡🌍

Extra kudos for not being overly polite but actually telling it as it is based on available scientific knowledge. Regarding the anti seed oil cultish people, who gives a damn about that crowd? If they want to stick to saturated fats only that's just fine. More seed oils for us 💪🏼 Again thank you for the great content you keep putting up, it's such a great time for the layman to be alive. Cheers mate
I mean I try to avoid seed oils not because I think they are bad but because they don’t improve taste nearly in line with their calorie content. Like butter at least tastes good, so I can kinda justify the calories but canola oil isn’t exactly something I want to put on a biscuit
The main argument is that oxidation doesn’t necessarily occur during RCT because they’re not long enough. Interestingly enough they can’t come up with a sound hypothesis to be tested, always arguing up on a new “ad hoc” thought experiment…
The LA veterans administration hospital study an 8 year long double blind RCT isn't long enough? The Finnish mental hospital study a 12 year randomized crossover trial isn't long enough?
i'd argue that any group of people in that community could be called a "religion" if people refuse to hear out/take into account evidence that doesn't fit their personal preference.
That is super fascinating-I wonder how this would correspond to something I read (on CNN of all places, of course) about Omega-6s impact on cancer/cancer treatment or something to that effect? If I could remember the article name I would link it
Omega 6 linoleic acid, at least per a 2021 meta-analysis of 19 cohort studies by Kim et al containing over 1 million people, actually suggests polyunsaturated fats reduce cancer mortality in a dose dependent manner. There is otherwise no significant effect of omega 6 itself independent of obesity or ultra-processed foods increasing cancer risk (Hanson et al 2020; Ederer et al 1971).
Hey this wasn’t What the fitness! Why the tone change when saying human randomised control trials? I don’t expect that tone with the educational series.
I think it's time for some of these researchers to explore comparisons between these fats/oils in higher calorie diets. When your calories are low, negative effects of even highly inflammatory foods are diminished. And not many people restrict calories in real life. That's one aspect of some of these trials that seriously separates them from the general public. But that's my opinion, and I'm not exactly the most informed on the subject, so take this with some caution. Thanks for the video, Dr Layne!

Seed oils are fine with moderation. Losing weight is simple. The problem is many people won't go through the frustration of true calorie or macro counting. Overusing oil increases calories quickly and leads to small and unsatisfying food portions or overeating calories. Cutting out too much fat makes food unsatisfying. Getting the balance right is a big key of fat loss. (I like moderately low fat food for fat loss, I get to eat bigger portions.)
Name me one other animal that needs to count their calories to maintain a healthy weight for the species in the wild. The problem is absolutely what we eat.
@@paulc5389 > in the wild Are we in the wild? We have sedintary lifestyles for decades. When we're not, it's easy to stay healthy on a whole foods diet.
Are there any RCT giving rancid vs fresh linoleic acid? Or would this be unethical? If the studies only use good quality oil then i can see a possible issue making assumptions based off this data.
@Parker_Miller_M.S. Omega-6 fats, like linoleic acid, can become rancid through a process called oxidation, which is a chemical reaction that breaks down the fat: Sunlight: Sunlight catalyzes the reaction that causes oxidation. Heat: Heat can trigger the enzymes that cause rancidity. Oxygen: Oxygen is involved in the chemical reaction that causes oxidation.
@cantstandya157 thanks for defining. But does any of it actually matter is the next question, beyond calorie intake and overall nutritional density of the diet. Basically, I'm not confident that if one has an overall health promoting diet that having an oil be heated makes any real difference. Or using an oil that has been exposed to sunlight makes nay difference. I would need to see that consumption of such oil actually reduces health by validated metrics in a controlled setting. I'm currently unaware of any such study.
@@Parker_Miller_M.S. This is where the issue is: the studies are done with good quality oil, and then people like Layne use this to make blanket statements on seed oils that could be sitting in a deep fryer for 15 days. I think there is nuance to this discussion; most people are either "ALL SEED OIL IS BAD!" or "LOOK AT THE RCT'S!".
@@cantstandya157 I recall a study referenced in a video by nutrition made simple which tested reheating the same oil about 15 times then having participants eat some food cooked in the oil. If memory serves there was 1 biomarker (I believe inflammatory related) that was increased but it was otherwise non-significant. I don't recommend or encourage people to eat deep fried or heavily fried foods anyways though, nor would any sensible person. I can see where you're coming from though.
I was anti-seed oil cult and this video changed my mind on seed oil consumption. I would like to see an analysis of seed oil v coconut oil for the same outcomes.
when the pacific islanders switched from coconut oil, to seed oils.. they became the healthiest population on earth. or did they... dont talk about "cults" before you research the damage done by the eugenic seed oils to entire populations.
Well, coconut is mostly saturated, so it's not going to be better than seed oils for sure. I wonder about olive vs seed oils though, as olive has much lower content of PUFAs and much higher concentration of polyphenols, so one "negative" and one "positive"
“Several studies indicate that high levels of polyunsaturated fatty acids (PUFAs) can damage mitochondria, with evidence showing that excessive PUFA intake can lead to increased mitochondrial reactive oxygen species (ROS) production, impaired mitochondrial respiration, and disruption of mitochondrial membrane integrity, potentially contributing to cell death in certain situations. “
Brutal and spot on a usual. Evidence is quite clear seed oils are better than saturated fat for metabolic health. I think there is one point worth mentioning. If we consume seed oils in the form of cake, deserts, chips and cookies it comes along with processed carbs, hyperpalatable foods with high caloric density and low satiety per calorie. They are way too easy to overeat, hard to moderate and hard to quit. I think ultra processed foods and junk food are the main cause of the obesity pandemic.
I need help! About the approximate 3:1 ratio our bodies need when it comes to omega 6's to omega 3's? That's still correct right?? If there are only so many desaturases and your system is flooded with omega 6's, won't that block the omega 3's from being utilized and cause the ldl levels to rise over time?? I'm not saying seed oils are toxic, but shouldn't there be a limit on how much we should consume?? Please, someone answer this!!
You're overthinking it dude. The stress from obsessing over your diet is more damaging than your PUFA ratio. Don't eat too many calories, eat less sat fat, less sugar, and eat plenty of fiber. Replace sat fats with PUFAs where you can, preferably fish based Omega-3. Stay calm
Per a September 2024 review with Bill Harris, lead author Katherine Jackson, they state the ratio of omega 3 to 6 is not that important (I'm paraphrasing)
@vegasbackgrounds3426 here is the title below. I was mistaken it's not Bill Campbell its Bill Harris who is one of the authors. I'm going to fix my prior comment. Beneficial effects of linoleic acid on cardiometabolic health: an update
Think you made a mistake and said alpha linolenic acid instead of gamma linolenic acid. If the research is showing that ALA is good vs saturated fat, well that's omega3 and not omega6 vs sat fat. Saturated fat in cocao or even eggs seems better than in butter. The cholesterol lowering margarines with plant sterols in them seem to lower cholesterol quite well. Can you get these plant sterols in whole foods? What do the studies show on people using these cholesterol lowering margarine vs placebo on overall health?
Okay. Let's add some facts. The industrial seed oils have lignans and vitamin E removed and replaced by BHA and BHT. BHA and BHT are toxins, removed relatively quickly by the liver yet still toxins. Lignans and vitamin E are bioavailable antioxidants that get into the human system, and by the way in proportions that reflect the source levels of PUFA (if you eat the whole food). PUFA without antioxidants yield oxidation products like MDA in the body. And, this liver stiffness thing: Doh. Saturated fats are stiffer. You want to cite health effects, then demonstrate in this case that this result equates to less healthy.

I would imagine a short-term nutrition study done on the Swedes wouldn’t translate to the rest of the world population as most diets aren’t Swedish, and the Swedish are a very homogeneous population.
Interesting points which warrant a deeper look. One of the issues sighted with seed oils, is that solvents such as hexane are used in the extraction process to extract oils from seeds and vegetables. Hexane is known to damage the gut lining and cause nerve damage even in small amounts. Hexane residue remains in the oil after processing is complete.
Even if we grant that to be true - it doesn’t seem to pan out when you look at actual health outcomes in humans consuming seed oils. Which ultimately is what we care about.

They’re always using studies that are conducted in other countries. Sweden mainly consumes fish…they don’t cook most of their dishes in seed oils. So they’re consuming minuscule amounts of seed oils and that doesn’t provide real results. Let’s see the study using a standard American diet.
so basically nothing is unhealthy. and yet we get sicker and sicker, interesting… my grandparents for example… they never overate (so it can’t be cuz of excess calories), never drank alcohol, prepackaged food, … etc. they had their own garden with fresh fruits and veggies. so they were moving around a lot too (slow steady exercise) but they did eat sugar (in home baked stuff), seed oils, … etc. what made them sick if these aren’t bad? simply age? my ass…
Layne is very easy to debunk if you pay attention to the response videos. He doesn't know a lick about mechanistic details of metabolism so he relies solely on the surface conclusions of the RCTs rather than actually getting into the weeds about what the data ACTUALLY points to.
@SullivanKelly85 from a researcher that studies mechanisms in a different field than nutrition (genetics) let me tell you: it is incredibly easy to work backwards from a conclusion and use existing literature to construct a mechanistic rationale that supports that conclusion. The reality is that the biological hairball (look it up) is so much more complicated than any subset of pathways within it. This is why in drug development, gene therapy development and nutrition we have to use empirical studies (like RCT) with rigorous statistical evidence. Mechanisms can help you conceive a study, but that's about all they are good for.

@@Parker_Miller_M.S. Why is it necessary? Biomarkers of health in the short term have mechanistic reasoning that are completely different from long-term adaptation. And to correct you: Studies consistently show that PUFA intake used in place of saturated show improved markers associated/correlated with heart disease etc. BIG DIFFERENCE. Which illustrates my point. Omega-3 intake for example lowers inflammation. Good thing, right? Now look up the mechanism by which it does this... Hint: it's probably not a good thing long term.
@@SullivanKelly85 long term outcomes and hard endpoints > mechanism. The long term data from RCTs and cohorts show lower risk of CHD, lower risk of stroke, and CVD mortality with high levels of tissue linoleic acid.

You have changed my mind on seed oils from your videos over the past few months. Thanks for making me turn my brain on🙏🏼
Best nutrition channel
Excellent discussion. Thank you.
yes! keep telling the truth
Maybe they are good for liver fat, but I eat reduced PUFAS because of inflamation.
He also mentioned studies showing PUFAs do not increase system inflammation.
Love this, thank you.
Doing crazy work Dr. Norton!
I enjoy your content and find it very informative, mostly without bias. In most studies, there are often missed avenues, but that's why we continue to research topics repeatedly. In the end, everyone must follow their own personal requirements. You may have a sensitivity that I may not have or a lifestyle that better supports one diet over another.
Awesome video! Thank you
How were the seed oils prepared and served? Were they in pills and not cooked? If so, then they were not served in the manner in which they cause the most damage. In other words, were they fried? If not, then nothing in this study means anything.
Yep, this is the problem: Layne will say it's nitpicking to ask for an RCT with oxidized omega-6 vs. fresh; I think it would be unethical. I understand nitpicking can be annoying, but it is literally how science improves incrementally.
Actually it doesn't matter :-) if you want more context you can search on RUclips for info.
EXACTLY
Not everyone deep fries their oil, bro. Heating it for cooking to saute something does not show to increase oxidized lipids or acids by much. It's doing it over hours and hours.
@nick7072 I agree with you. In fact I would find it odd if people treated their oils at home the way a restaurant treats them: heating to high temps and reheating for days sometimes. That would be weird. But every restaurant does this. Everyone of them. So, there's ground for nuance here. The idea that nuance is nitpicking is anti scientific in my opinion.
Great vid as usual
Just want to point out in case anyone else is confused; Layne mistakenly said "alpha linoleic acid" a couple times in the first half of this video. "Alpha linoleic acid" does not exist, and I'm sure he meant "linoleic acid", which is the predominant Omega-6 PUFA found in seed oils. He even correctly says "linoleic acid" at a later point in this video.
This is just a slip of the tongue, accidentally combining "linoleic acid" with "alpha linolenic acid", which is an Omega-3 PUFA found in some plant foods, including canola oil ;)
Maybe he just mispronounced alpha-linolenic
Seed Oils are like firefighters. They are at the scene of the fire but not the problem. The problem is that they are often found In hyperpalatable foods. Years ago my brother and I interviewed Stephen Phinney, the keto king that most people based their research in keto on. He told us seed oils were no different than any other fat and not an issue on keto. I thought he was mistaken and just didn’t know the “new” info, but now I realize there has been a ton of information on them for years. I have no desire or reason to ever consume them however in talking to really smart people like Alan Flanagan, and Layne, I don’t think we need to worry about them if they are on your steak or in your salad. Worry about them in Oreos.
I have seen several videos in which Stephen Phinney warned people to stay off seed oils.
@@itzakehrenberg3449 I agree with you. I've seen many videos with him. He even has a chart showing this.
Other than possibly smoking consuming seed oils is probably one of the highest causes of oxidation potentially leading to heart disease and stroke.
Yes of course. Then Mc Donalds fries are bad for you not because of seed oils but because of... potatoes? LOL
@@paulc5389 > consuming seed oils is probably one of the highest causes of oxidation
Proof? Studies don't show increased oxidation or inflammation in humans.
thanks
Whole food is best, without a doubt. But that doesn't mean that a processed food like seed oils is necessarily bad for you.
Gil Carvalho made a video covering numerous studies on seed oils, which showed basically the same thing, that they do not have a detrimental effect on one's health. I'm still not sold completely, but the more I hear things like your video I have to be willing to reconsider.
Love it. 😊
I think what people who are against the seed oils need to think about is
1) this study doesn't prove or even suggest that seed oils are "good" for you - it shows they have positive effects with 1 thing.
2) think about the _source_ of the omega 6's - it's not ONLY found in seeds or whatever other "bad" things, it can be found in what you deem to be healthy foods too.
3) remember the "real problem" with omega 6 is not the omega 6 itself but rather the ratio of omega 6 to omega 3 (maybe 9 too idk i'm not a scientist, just trying to remind people of what I've seen/heard to hopefully avoid foolish rage-fueled arguments) and that having a lower amount of 6 vs 3 is supposed to be "better"
The only problem is if omega3 is low and therefore o6/o3 ratio is high. High Omega6 to omega3 is positive if both are high. As such, ratios are useless. Stick to your quackery, but do it elsewhere.
Watch Dr Bill Harris on omega 6 to 3 ratio, there's a nice clip with rhonda patrick.
@@ladagspa2008 it's not quackery bucko.
I made no actual claims.
as I said, I'm only trying to remind people that it's not necessarily that omega 6 is bad. people tend to change their arguments if something even slightly challenges them.
What is your take on intestines cancer and omega6? I've read that if omega6 and omega3 levels are not in balance, high omega6 levels may increase the risk of cancer

Layne, next time please review the recent study on FUPAs for us. I haven't come to a decision on them yet.
How do we know if the trials were paid off by big canola oil? Joking but sort of not.
Please do the seed oils linked to colon cancer that just came out next!
Ultraprocessed foods low in fiber may increase risk of colorectal cancer, but the oils themselves do not have such evidence.
Watch Gil Carvalho of Nutrition Made Simple.
@@HAL-zx1bw the study your mentioning was a lipidomoics in vitro study. One cannot come to the conclusion that seed oils cause colorectal cancer from that study design in humans. Existing RCTs and meta-analysis of RCTs do not suggest an increase in cancer risk.
The episode I’ve been waiting for! There’s a whole industry on trying to avoid Pufa’s!
N =48, 12 Week-long open-label "randomized control trial" with self supported food diaries. Need I say more?
Think this hammers home the idea that we are simply consuming too many calories and the question is how do you effectively change the behavior of a population that is over-consuming. I would advocate banning advertising of foods that are high in calories and low in satiation. Empowering individuals to stick with their dieting without the constant temptation created by the billions spent to foods that should be rare treats.
Total agreement with you!
Calories are not consumed. They are not a physical thing we consume. My goodness. It’s about what food is optimal for humans and how that food affects your hormones. This is why I now “consume” 4000 calories of animal foods and am leaner than when I couldn’t lose stubborn weight “consuming” 2000 calories. Let’s not even get into the mental health benefits. Unbelievable.
@@WilliamBTCWallace ,
Nonsense.
@@arvidlystnur4827 No it’s not nonsense at all. It’s reality. Carnivore also healed my psoriasis. I could care less if you believe me. I tried it because so many others had the same results. Get over it.
Years ago when I was vegetarian in the majority of my fat came from nuts especially peanut butter
Even though my diet wasn't exactly healthy I had endless energy , then in 2018 when I try to low-carb diet and I ate so much animal fat and yes I broke my vegetarianism
The next year I felt like garbage like a big giant truck fell on top of me and I was suffering, I went to the doctor did blood work and my doctor said your liver enzymes are too damn high you need to bring them down,, she didn't tell me how to bring them down she just told me that's really really bad so years later here today
My liver enzymes finally went down when I went back to eating more plant-based but a much more healthier balanced diet compared to what I was doing before but the low-carb diet was one of my biggest regrets I don't even know why I did it I was desperate I guess but I hated eating that way the whole time,, we do crazy shit when we're desperate
what kind of low-carb diet?
@DragoNate it doesn't matter because all low-carb diets are so miserable and disgusting and boring to me,, if it's true that you should enjoy the diet you're doing then low-carb diet was like being sodomized over and over and over again and I hate it every second of it
I've done a lot of stupid things in my life but a low-carb diet was at the TOP OF MY LIST OF ONE OF THE STUPIDEST THINGS I'VE EVER DONE!!!
@DragoNate I foocking love eating CARBSSSS!!!! and if that offends
Your ANTI-CARB CARB PHOBIC feelings oh well too bad so sad!!!
@@daysoftheboo You are so misinformed it is sad.
Go look into professor Thomas Seyfried Boston College and you will realize that humans preferred state is probably ketosis. Not out of choice, but out of reality. Also go listen to Miki Ben Dor on why humans are hypercarnivores.
You'll realize quite fast that humans are hunter gatherers. We ate mostly meat and fat from large ruminant animals. This is how humans have evolved and if you believe in evolution your cells want this not some carbs.
Lastly, go listen to Bart Kay and you'll realize that Layne Norton hasn't got a clue what thermodynamics is.
But, you do you.
@daysoftheboo that is your personal experience and it's true, some people feel terrible on low carb diets but many others feel great following a low carb/ketogenic diet. I've been eating this way for years and feel 1000x better eating low carb vs eating a high carb diet when I would have fluctuating energy levels, cravings, bloating and I didn't enjoy the food nearly as much as on my keto diet. To each their own, people should follow whatever works best for them.
I think most “anti seed oil” people argue that seed oils aren’t bad, but it’s how they’re made that makes them bad. Mechanical process for making seed oils is not considered bad, but the chemical process in which they are would be considered bad. Hexane, which is a hazardous gas, is used in the process and they say it’s evaporated out, but the FDA doesn’t actually test for hexane residue. Later in the process the oil is bleached to make it clear. So hexane and bleach are the big reasons anti seed oil people avoid seed oils.
No one is arguing that sunflower, corn, soybean etc seeds are bad for you. It’s why extra virgin olive oil is popular. It’s typically cold pressed rather than chemically made.
@@mricecream-clashofclansyeah we are. Any oil that's likely oxidated or highly prone to oxidation is bad for you. Even cold pressed olive oil will oxidate if it's sat in a bottle for ages after being pressed or if you cook with it.
It appears in the human randomised control trials that hexane residue is probably good for you. Also the bleaching. Maybe it’s the pufas that are so healthy, that they compensate double for the hexane and bleach. 🤡🌍
You take in more hexane daily via vehicle fumes than you will ever do through seed oils. Human RCTs biach
@@mricecream-clashofclans Studies dont show that they are bad. You can claim that there is hexane all you like, but there is no evidence for that.
Have you got any vids on Omega 3's and 6's and the benefits etc,

Again thank you for the great content you keep putting up, it's such a great time for the layman to be alive.
Cheers mate
I mean I try to avoid seed oils not because I think they are bad but because they don’t improve taste nearly in line with their calorie content. Like butter at least tastes good, so I can kinda justify the calories but canola oil isn’t exactly something I want to put on a biscuit
The main argument is that oxidation doesn’t necessarily occur during RCT because they’re not long enough. Interestingly enough they can’t come up with a sound hypothesis to be tested, always arguing up on a new “ad hoc” thought experiment…
The LA veterans administration hospital study an 8 year long double blind RCT isn't long enough? The Finnish mental hospital study a 12 year randomized crossover trial isn't long enough?

So should I eat seed oils or no
Eat them in moderation in conjunction with a balanced diet and consistent exercise routine
It's interesting to hear the term "anti-seed oil religion" as it makes on wonder how many other religions exist in the nutritional science community.
i'd argue that any group of people in that community could be called a "religion" if people refuse to hear out/take into account evidence that doesn't fit their personal preference.
All of them who just base their beliefs on zero or little or dubious evidence…. So all the extreme good tribes
I like watching them fight,
I put This One on "ALGORITHM!" & "RANDOMIZED CONTROLLED TRIALS" Cult.
That is super fascinating-I wonder how this would correspond to something I read (on CNN of all places, of course) about Omega-6s impact on cancer/cancer treatment or something to that effect? If I could remember the article name I would link it
Omega 6 linoleic acid, at least per a 2021 meta-analysis of 19 cohort studies by Kim et al containing over 1 million people, actually suggests polyunsaturated fats reduce cancer mortality in a dose dependent manner. There is otherwise no significant effect of omega 6 itself independent of obesity or ultra-processed foods increasing cancer risk (Hanson et al 2020; Ederer et al 1971).
HUMAN RANDOMIZED CONTROL TRIALS
for teh algorithm
Hey this wasn’t What the fitness! Why the tone change when saying human randomised control trials? I don’t expect that tone with the educational series.
everyday I love getting my daily dose of seed oils! LA and ALA FTW
I think it's time for some of these researchers to explore comparisons between these fats/oils in higher calorie diets. When your calories are low, negative effects of even highly inflammatory foods are diminished. And not many people restrict calories in real life. That's one aspect of some of these trials that seriously separates them from the general public. But that's my opinion, and I'm not exactly the most informed on the subject, so take this with some caution.
Thanks for the video, Dr Layne!
Layne, any thoughts on Peter Rogers' anti-fat arguments (i.e., that there are no good fats)?
Oof. The truth burns. Thanks for sticking to the rigorously gathered and analyzed data!
I quit seed oils and i am not missing out on anything. and just my own results are after going on a carnivore type diet, I have not had a case of swollen knees or joints, and its been a regular thing for me for 25 years because i used to eat anything and everything. was it the seed oils causing my problem? I dont know but i sure dont miss it
I understand rationally that the evidence so far hasn't proved the seed oils = bad theory, but then why do I feel so much better on butter than margarine? Why do I feel like total garbage after fried foods and ultra processed sauces/dressings? 🤔
@@theswoletariat3479ummm…cuz all those foods you mentioned are garbage🤷🏻♂️. So let me guess this straight, you are making healthier food choices (likely consuming WAY less butter than you ever consumed in ‘bad oils’ eating all those fried foods) and you feel better? 😂😂😂. Do the math.

Seed oils are fine with moderation. Losing weight is simple. The problem is many people won't go through the frustration of true calorie or macro counting. Overusing oil increases calories quickly and leads to small and unsatisfying food portions or overeating calories. Cutting out too much fat makes food unsatisfying. Getting the balance right is a big key of fat loss. (I like moderately low fat food for fat loss, I get to eat bigger portions.)
Name me one other animal that needs to count their calories to maintain a healthy weight for the species in the wild. The problem is absolutely what we eat.
@@paulc5389 > in the wild
Are we in the wild? We have sedintary lifestyles for decades. When we're not, it's easy to stay healthy on a whole foods diet.
Are there any RCT giving rancid vs fresh linoleic acid? Or would this be unethical? If the studies only use good quality oil then i can see a possible issue making assumptions based off this data.
What defines "rancid linoleic acid"?
@Parker_Miller_M.S. Omega-6 fats, like linoleic acid, can become rancid through a process called oxidation, which is a chemical reaction that breaks down the fat:
Sunlight: Sunlight catalyzes the reaction that causes oxidation.
Heat: Heat can trigger the enzymes that cause rancidity.
Oxygen: Oxygen is involved in the chemical reaction that causes oxidation.
@cantstandya157 thanks for defining. But does any of it actually matter is the next question, beyond calorie intake and overall nutritional density of the diet. Basically, I'm not confident that if one has an overall health promoting diet that having an oil be heated makes any real difference. Or using an oil that has been exposed to sunlight makes nay difference. I would need to see that consumption of such oil actually reduces health by validated metrics in a controlled setting. I'm currently unaware of any such study.
@@Parker_Miller_M.S. This is where the issue is: the studies are done with good quality oil, and then people like Layne use this to make blanket statements on seed oils that could be sitting in a deep fryer for 15 days. I think there is nuance to this discussion; most people are either "ALL SEED OIL IS BAD!" or "LOOK AT THE RCT'S!".
@@cantstandya157 I recall a study referenced in a video by nutrition made simple which tested reheating the same oil about 15 times then having participants eat some food cooked in the oil. If memory serves there was 1 biomarker (I believe inflammatory related) that was increased but it was otherwise non-significant. I don't recommend or encourage people to eat deep fried or heavily fried foods anyways though, nor would any sensible person. I can see where you're coming from though.
@biolayne GOAT !
I was anti-seed oil cult and this video changed my mind on seed oil consumption. I would like to see an analysis of seed oil v coconut oil for the same outcomes.
when the pacific islanders switched from coconut oil, to seed oils.. they became the healthiest population on earth. or did they... dont talk about "cults" before you research the damage done by the eugenic seed oils to entire populations.
i also think you are a bot but what evs.
Well, coconut is mostly saturated, so it's not going to be better than seed oils for sure. I wonder about olive vs seed oils though, as olive has much lower content of PUFAs and much higher concentration of polyphenols, so one "negative" and one "positive"
@@MPiotroff is saturated fats bad? why? say who?
@@tallesttreeintheforest Yes. If you don't know the science, that's your problem, I'm not going to waste my time here
Moderation, in most things, is not bad. Seed oils is one of those things.
Videos like this don't tell the whole story. There's lots of reasons to stay away from seed oils that are completely unrelated to this
Such as?
One or two of them in just a short sentence would be super helpful as I haven't heard these
“Several studies indicate that high levels of polyunsaturated fatty acids (PUFAs) can damage mitochondria, with evidence showing that excessive PUFA intake can lead to increased mitochondrial reactive oxygen species (ROS) production, impaired mitochondrial respiration, and disruption of mitochondrial membrane integrity, potentially contributing to cell death in certain situations. “
i’ve been going insane seeing people say SEED OIL BAD like it’s common knowledge
Brutal and spot on a usual. Evidence is quite clear seed oils are better than saturated fat for metabolic health.
I think there is one point worth mentioning.
If we consume seed oils in the form of cake, deserts, chips and cookies it comes along with processed carbs, hyperpalatable foods with high caloric density and low satiety per calorie. They are way too easy to overeat, hard to moderate and hard to quit.
I think ultra processed foods and junk food are the main cause of the obesity pandemic.
I need help! About the approximate 3:1 ratio our bodies need when it comes to omega 6's to omega 3's? That's still correct right?? If there are only so many desaturases and your system is flooded with omega 6's, won't that block the omega 3's from being utilized and cause the ldl levels to rise over time?? I'm not saying seed oils are toxic, but shouldn't there be a limit on how much we should consume?? Please, someone answer this!!
You're overthinking it dude. The stress from obsessing over your diet is more damaging than your PUFA ratio. Don't eat too many calories, eat less sat fat, less sugar, and eat plenty of fiber. Replace sat fats with PUFAs where you can, preferably fish based Omega-3. Stay calm
Per a September 2024 review with Bill Harris, lead author Katherine Jackson, they state the ratio of omega 3 to 6 is not that important (I'm paraphrasing)

Beneficial effects of linoleic acid on cardiometabolic health: an update
I have no qualms with seed oils. The only oil I ever really eat is olive oil since my diet is primarily animal foods and some salads.
My brain has not left my skull, yet..
Think you made a mistake and said alpha linolenic acid instead of gamma linolenic acid. If the research is showing that ALA is good vs saturated fat, well that's omega3 and not omega6 vs sat fat.
Saturated fat in cocao or even eggs seems better than in butter. The cholesterol lowering margarines with plant sterols in them seem to lower cholesterol quite well. Can you get these plant sterols in whole foods? What do the studies show on people using these cholesterol lowering margarine vs placebo on overall health?
Layne should have Bobby Parrish on from FlavCity. He's one of those guys who is crazy about seed oils.
bobby the zest king
You mean about NOT consuming seed oils.
When you said "but big food" i thought for a second you were going to blame potatoes.😂
Okay. Let's add some facts. The industrial seed oils have lignans and vitamin E removed and replaced by BHA and BHT. BHA and BHT are toxins, removed relatively quickly by the liver yet still toxins. Lignans and vitamin E are bioavailable antioxidants that get into the human system, and by the way in proportions that reflect the source levels of PUFA (if you eat the whole food). PUFA without antioxidants yield oxidation products like MDA in the body. And, this liver stiffness thing: Doh. Saturated fats are stiffer. You want to cite health effects, then demonstrate in this case that this result equates to less healthy.
> vitamin E removed
Wtf? Why would anyone even do that? I still see vitamin E on my refined sunflower seed oil bottle.
Sounds like a conspiracy.

You're welcome.
I would imagine a short-term nutrition study done on the Swedes wouldn’t translate to the rest of the world population as most diets aren’t Swedish, and the Swedish are a very homogeneous population.
Interesting points which warrant a deeper look.
One of the issues sighted with seed oils, is that solvents such as hexane are used in the extraction process to extract oils from seeds and vegetables.
Hexane is known to damage the gut lining and cause nerve damage even in small amounts.
Hexane residue remains in the oil after processing is complete.
Even if we grant that to be true - it doesn’t seem to pan out when you look at actual health outcomes in humans consuming seed oils. Which ultimately is what we care about.

My comment is not a rebuttal in any way to this video or and piece of science. So for years i couldn’t lose weight below 214lbs.

Perhaps you lost weight because you stopped eating a high calorie food?
I don't eat seeds or seed oils only fruits , then leave the seed in the soil.
I don't care what kind of oil or fat it is, if you eat too much of it there's going to be a serious problem. It's called overconsumption.
That can be said for many things.

but they did eat sugar (in home baked stuff), seed oils, … etc.

Layne is very easy to debunk if you pay attention to the response videos. He doesn't know a lick about mechanistic details of metabolism so he relies solely on the surface conclusions of the RCTs rather than actually getting into the weeds about what the data ACTUALLY points to.
@SullivanKelly85 Which is pretty much true of everything and everyone on the Internet. Thanks to confirmation bias.
@SullivanKelly85 from a researcher that studies mechanisms in a different field than nutrition (genetics) let me tell you: it is incredibly easy to work backwards from a conclusion and use existing literature to construct a mechanistic rationale that supports that conclusion. The reality is that the biological hairball (look it up) is so much more complicated than any subset of pathways within it. This is why in drug development, gene therapy development and nutrition we have to use empirical studies (like RCT) with rigorous statistical evidence. Mechanisms can help you conceive a study, but that's about all they are good for.
Thanks for calling out the anti-Seed oil crazies! They dont like it when the facts don’t agree with their agenda and twist themselves in knots trying to explain it!
BUT BIG FOOD!!
regardless…look up how seed oils are made…then come back to me.
@@MrWingiii That is an app3al to nature fa11acy though. We should not care how scary things look being made, all that matters is how it affects the body.
@@MrWingiiihave you opened up the meat in a mussel and saw what it looks like? I eat the mussel based on the taste and nutritional profile and forgo how it looks inside the flesh. Just like I’m not interested how something is made but how my body uses it.
@MrWingiii 😂🙃🤣

Watching this as I spread butter on my soy and linseed toast 😅 (relax it’s grass fed cultured butter 😉)
If we're not to believe in mechanistic data and rodent studies then I'll wait until Layne designs a 25 year RCT on seed oil/PUFA consumption😂
Why is that necessary? Also it'll never happen. Cohorts consistently show health benefits to unsaturated fat used in place of saturated fat. RCTs also show reduced heart disease and no risk for cancer.
@@Parker_Miller_M.S.except that's not true. Data on consuming more PUFAs does NOT show a reduction in heart disease outcomes it shows a reduction in LDL. Which we now know the levels themselves of aren't causal to heart disease.
Even Keys himself had data showing people who ate a lot of PUFAs got ill and had worse all cause mortality and he just hid it until it was dug up years later.
@@Parker_Miller_M.S. Why is it necessary? Biomarkers of health in the short term have mechanistic reasoning that are completely different from long-term adaptation. And to correct you: Studies consistently show that PUFA intake used in place of saturated show improved markers associated/correlated with heart disease etc. BIG DIFFERENCE. Which illustrates my point. Omega-3 intake for example lowers inflammation. Good thing, right? Now look up the mechanism by which it does this... Hint: it's probably not a good thing long term.
@@SullivanKelly85 long term outcomes and hard endpoints > mechanism. The long term data from RCTs and cohorts show lower risk of CHD, lower risk of stroke, and CVD mortality with high levels of tissue linoleic acid.
We are extremely unlikely to ever see a 15+ year RCT looking at oils and cardiometabolic health but we don't need one to infer from the existing data that the oils are better for cardiometabolic health than saturated fat.
@@Parker_Miller_M.S. "WE" don't need anymore data? Maybe you don't. I've read many of these RCT designs and the data isn't very compelling to me. Maybe they should stop studying this issue then... The science (TM) has been set? I'll link back here an article outlining the HUGE problem researchers are finding with RCTs in general. They are definitely no longer seen as the "gold-standard" in many circles.
Another comment Layne wont read -- for the algo.
@8:15 oh thank you for clarifying your close mindedness.
hopefully this guy is removed from my algorithim soon.
You realise by commenting you directly affect the algorithm to promote videos 😂. If you don't like it, don't watch, don't comment, stay away.
@@noggintube yes, I was hoping one day he would change but some people are stubborn. Same stubborness made him squat 600 lbs. Oh well moving on
