Video compares PUFA with SFA... WFPB works best with none to negligible Fat or Oil due to Krebs cycle and definitely for Diabetics who can go either HCLF or LCHF/keto for glucose control with pluses/minuses of both approaches. NO OIL wins hands over Any Oil for HC as lower the fat, more efficient Krebs cycle. Combo can result in reverse flow in ETC and can result in electron bombardment definitely for compromised or diabetics. With Low SOD, electrons and O2 is Superoxide followed by Peroxide, ROS, Oxidative Stress, and inflammation... Besides double bonds are the weakest links with more electrons and H+ or pH lowering - another Homeostasis issue.. Bottomline stay away from Oils ... Makes no sense to compare bad vs bad....

According to Dr. Chris A Knobbe and Dr. Catherine Shanahan. Seed oils are the cause of lots of disease.

[@therealmitch-a-palooza7262]

While I appreciate the content, there's a gaping hole in these studies, and the conclusions drawn in this video: they do not specifically speak to seed oils produced with industrialized methods. Seed oils are typically exposed to super-high heat and chemical solvents during manufacturing to turn them into palatable products. Simply giving someone lineolic acid and doing a blood test does NOT mean that industrially-produced seed oils are safe. Were the seed oils used in these studies cheap off-the-shelf, non-organic products that consumers typically consume? I think the answer to that question is...."who knows". These manufacturing processes inevitably cause oxidation of the oil. I recall one study where a university tested a couple dozen different brands of avocado oil, and all but two brands showed extensive oxidation right out of the bottle. Most seed oils are not really natural products, as seed oils require a ton of heavy-handed techniques to rid them of their funkiness. I don't buy that mass-produced seed oils are good for health. Even if these oxidized fat molecules and other free radicals in them don't result in inflammation high enough to affect blood markers, I don't think it truly matters, because oxidized lipids are not health-positive regardless. Also, these blood tests are not designed to measure subtle changes in peoples' inflammatory loads, nor is it necessarily true that low-grade food-based inflammatory responses are captured by those specific blood markers. You've even published videos acknowledging the fact that heart disease is the end-product of chronic, low-grade inflammation cause by diet, rather than cholesterol and (healthy) fat; so the question is....why trust this data when traditional blood markers did not aid in detecting/discovering that, either? It seems to me that chronic, low-grade, dietary-induced inflammation is undetected by blood markers such as TNF and C-ReP. Industrially-produced seed oils and agricultural chemicals are two of the main things to come onto the scene in peoples' diets, and coincide with the skyrocketing in chronic health issues. And while it's true the science isn't wholly conclusive yet, there are so many better options out there, including olive oil and naturally refined avocado oil....that going for hexane-extracted canola oil is probably the wrong choice for peoples' everyday cooking. What's more, oils that are not bastardized in the production process retain their natural antioxidants, which are beneficial to health, and mitigate oxidation caused by high heat cooking. As such, I don't really consider any of the studies mentioned in this video to be remotely conclusive on the topic. Equally puzzling is the conclusion you drew out of nowhere trying to discount the fact it’s been well established that Omega-6 fatty acids are inflammatory.

Toxic and inflammatory, ok, but do seed oils slow metabolism? Here studies are conflicting, but on balance, it appears yes they do. When eating PUFA, your body will store PUFA. Normally the body stores fat as SFA and MUFA. This store of PUFA slows the metabolism as it is released. This is the problem with seed oils. The impact on metabolism. It takes years to change out the fat in a body, so short term studies may not be accurate, especially when dieting. Release of stored PUFA may be the cause of a slowed metabolism when dieting.

[@johnhawkins3507]

@@stevenr5149 I am not aware of any human studies, only rat studies. But I would not say this is my theory. Studies show it is a problem in rodents, but from this we cannot conclude seed oils are good for humans. No human studies, that I am aware of, exist to demonstrate seed oils do not harm metabolism. Another problem with seed oils: "Heating unsaturated fats like vegetable oils to high temperatures during cooking or food processing can create trans fats. This is because high heat triggers thermo-oxidative changes in oils." So I believe Dr. Stanfield needs to update his video, to be inclusive of these problems with seed oils.

[@Mathias-ji2qc]

There is an issue in this discussion that I observe often in science: you have one group of people - including many doctors and surgeons highly focused on real life experience and can explain cellular processed in the body very detailed saying one thing based on experience. Another group focused on theoretical studies and is highly skilled in reading those say the first group is wrong based on data. Now we have two expert groups claiming science with contradicting results. You need to sit together and have a discussion and then do proper research where the disconnect between observational studies and individual experience comes from. It happened often that studies all showed the same picture until somebody realised "wait a minute we do not measure right" and wham, suddenly everything was different and real life and theoretical data could be aligned. Reading lots of studies and then saying "this is the evidence" is not how science works. One issue I experienced myself: without real life expertise it's extremely difficult to understand the limitations of studies and you are tempted to give them way too much weight, have a hard time to distinguish if it's single point of data or applies to a wide range. At this point I don't trust any source, I am open for both sides to be right but please do the science and don't fight for who is right. it'd be also worth taking to people who actually manufacture oils some of them can tell you a book about how the process - starting long before the pressing - influences the quality of the oil, that also has to taken into account. In another video an immunologist raised concern that for studies fresh bottles are used while in households oils are opened and used over months. Yeah, nice you heat up that oil for 10 hours, now open the bottle, take out a sip every day and do the experiment again when the bottle is almost used up. Still the same results? See how important the setup of a study is? How important it is to have the connection to real life?

[@IanRushtonMusic]

Science evolves, and sometimes findings from observational studies don’t perfectly align with clinical outcomes. That's where large-scale, well-controlled studies come into play-to systematically address potential biases or oversights in smaller, real-world observations. It’s also important to recognise that anecdotal experience, while valuable, is inherently limited and prone to bias. This is why rigorous studies are so essential-they allow us to test hypotheses under controlled conditions and isolate specific factors to see if the results hold up across different scenarios. That doesn’t mean we shouldn’t keep questioning or re-evaluating our methods, but it also means we can’t dismiss well-conducted studies simply because they don't align with individual experiences. It’s not a battle of who's right or wrong, but rather a continual process of refining our understanding.

[@Mathias-ji2qc]

@@IanRushtonMusic I don't know if you got the point I was trying to make: the size of the study only eliminates a numerical bias, but not the bias of a wrong approach itself. Especially in medicine the way studies are normed can lead by principle to unusable data. Often we need to look much more on the setup of the study than the outcome. And that is my point: only if you are able recognising the limitations from the setup of the study you are able to interpret it. Anybody who goes trough studies without explaining their limitations and how those limitations can influence the data to the audience doesn't teach knowledge. To explain limitations you have to be able to understand them. But if you are more into theory it is extremely hard to understand limitations, for that you need to have an experience guy who might not be able to work with the big data. But he can help the big data guys to get the data right. And this is not happening, instead the big data guys and experience guys try to prove each other wrong. So in the end we know nothing but have to chose who to believe because the data is contradicting itself. That is not science, that is religion!

[@IanRushtonMusic]

@@Mathias-ji2qc Just to clarify-when you talk about studies, are you focusing mostly on observational or epidemiological studies? Because it's worth noting that there are also countless randomized controlled human trials (RCTs) - that's what I am drawing from, (in particular several meta-analysis covering over 60 such RCTs). They provide higher-quality evidence by controlling for variables and randomizing participants, which reduces biases inherent in observational research. RCTs are designed specifically to eliminate many of the limitations you’ve mentioned, offering stronger data on cause and effect. While observational studies are useful for generating hypotheses, they can’t establish causality as well as RCTs can. The good news is that when it comes to things like diet and health, there’s a significant body of RCT data to help clarify the picture, and they don’t suffer from the same design limitations you see in observational studies. In other words, it’s not just a matter of belief or anecdote-there is rigorous, controlled research out there that supports many of these conclusions.

[@Mathias-ji2qc]

​@@IanRushtonMusic I think we still talk about different things. If I don't express myself clear please let me know it's not easy for me to go this complex in text in english. RCTs don't necessarily show you if there was an error in the setup of the study - maybe the same error was done in all of them because that's what the standard approach is. It works better for medication where you want to have one outcome and if that is achieved the medicine works. But you can't go with that approach into nutrition. A common error is: stressor - normed time frame - measurement. There are not many studies in which a complete observation of almost the complete vital picture of a human was done over a period of several months while also the complete life of these people was recorded. I don't know if there is a single one where n is of statistical relevance. Bias is only one factor, but even without bias the human is so complex that many studies fail to have a satisfactory answer because they were too simplified. You might not notice change in the observed area - what the aim of the research was - but have reactions in others that are missed, and these maybe months later lead to changes in the observed area - long after the study was closed. And that is where doctors who treat one patient over years have more knowledge where and what to look for, but they only have like 20-100 patients that are of interest for that, which is too little for statistical significance. On the other hand you have specific studies with huge numbers that lack the detail the doctor goes into with 1 patient. These 2 you have to combine. For this example with seed oils: do the study with a lot of different types, different production method, different shelf life. Then also different usage time in which the bottle is opened. And then observe the people over at least 12 months. Record all their diet and stress levels so because psychological stress that leads to inflammation could manipulate the picture. But also have a full vital check before to see what people started off from, how was the mineral household of the body? Blood tests don't cut it, they don't work for minerals like copper, zinc or B12, also Vitamin D you can have in active or inactive form all these are important when it comes to metabolism because it all influences nutrients work on the body. If you use a meta analysis over 60 RCTs you need to read the setup of all those 60 studies, get the limitations - know enough of metabolism to even see where a lack of measurements leads to a blind spot in the data. Like if there is not enough zinc the body can't convert Vitamin D from inactive to active - so any vitamin D study that doesn't include zinc levels might be limited already. Then first see if these blind spots overlap, because if they do and you combine those 60 you still have no solid data.

[@IanRushtonMusic]

@@Mathias-ji2qc You make some valid points, the complexity of nutrition is undeniable and it's true that no study is perfect, and RCTs-like any research-can have limitations. However, to my mind it seems very unlikely that all 60-odd peer-reviewed RCTs in these meta-analysis would share the same fundamental shortcomings, especially since they are often conducted by different teams in different settings with different protocols. And of course, it's probably much more that 60 RCT's - that's just the ones courtesy of three meta studies that I quickly identified. The diversity in study design helps to balance out individual weaknesses. Meta-analyses also take these limitations into account by assessing the quality of each study and adjusting for any potential biases. Flawed, or at least studies with obvious limitations are often given less weight or even excluded from the analysis. While individual RCTs might not be perfect, when you pool data from many high-quality studies, you typically get a more reliable overall picture. Of course, RCTs aren't immune to limitations, particularly when it comes to the complexity of human nutrition. But I think it’s important to differentiate between some degree of limitation and a fundamental shortcoming across an entire and significantly sized body of research. Broad issues like those you raise would likely have been identified and addressed by researchers over time.

[@IanRushtonMusic]

The seed oil debate highlights an interesting contradiction in nutrition advice. While many influencers warn against seed oils, citing toxicity concerns, the bulk of scientific evidence suggests they're safe and potentially beneficial. Interestingly, those who support seed oils often caution against overconsumption of ultra-processed foods. Here's the catch: seed oils themselves are highly processed products. Their production involves intensive industrial methods like pressing, refining, bleaching, and deodorizing. This raises a question: how do we reconcile the support for seed oils with the general advice to limit ultra-processed foods?

THANK YOU!!! In addition to what you said, none of them talk about the unfiltered naturally expelled seed oils. They exist. Are those bad too?

The other thing is everyone assumes that Italians who live longer, don't use seed oils. This is simply untrue! No one was frying in olive oil..not only would it be too expensive, but it also can't stand the heat. Not everyone used lard like everyone believes. I was just in Italy and my family still has seed oil in their cupboards. Here is what has changed in the last few decades. People are sitting more. We have more and more women working now than ever before. Those ladies who used to be home running after kids, gardening, cleaning house, etc., are now plopped in front of a computer. We have a messed up sense of what exercise is. One hour in the gym isn't doing anything for anyone if they sit on the couch, or in front of a desk, the rest of the time. Now there are fewer people making home cooked meals, and there are more and more snacks in people's pantrys. For Europeans, food comes before their homes and their cars, and most people cook their own meals from scratch...even if they do use seed oils some times. Europeans still believe in fresh air and long after dinner walks. Another thing that Europeans don't do the way Americans do is consume alcohol. Kids are starting younger and younger. It starts before college and they drink to oblivion, not just one or two. By the time they are adults, they still need their drinks. Alcohols is worse than seed oils. And as for diseases, doctors need to START paying attention to their patients medications. Could they be reacting to one of them? They all know that they come with side effects, but rarely do they change out their meds. People need to start talking about that. The bottom line is, we were not meant to sit all day.

Seed oils are often heavily processed using high heat and chemical solvents, leading to the formation of harmful compounds like trans fats and oxidized lipids. These substances have been shown to contribute to oxidative stress and cellular damage. In contrast, natural fats from whole foods, such as olive oil, butter, and even animal fats, are more stable and offer essential nutrients without the inflammatory risks.

Good video. Though you are grouping all seed oils together, and showing a temperature study on just canola, some oils are worse than others. Canola is arguably neutral, maybe somewhere in the middle. Soybean, corn, etc. either are bad for you, or don't have enough human studies proving they are safe. "After warming, soybean oil suffers degradation due to oxidation of triglycerides with formation of peroxides and increase in free fatty acids. The formed compounds during degradation of soybean oil are associated with cardiovascular diseases, arthritis, precocious aging and cancer. " "Soybean oil induces neuroinflammatory response through brain-gut axis under high-fat diet"

[@IanRushtonMusic]

While some studies have associated degraded oils with various health issues, it's crucial to note that these associations don't necessarily imply causation. The health effects often depend on the amount consumed, frequency of consumption, and overall dietary context. I'm guessing the comment regarding neuroinflammatory responses was the study that was conducted on mice, not humans, which is an important limitation when extrapolating results. It focused on high-fat diets, which may not reflect typical human consumption patterns. Generally, Single studies should be interpreted cautiously. Scientific consensus emerges from multiple studies over time.

[@jaro6985]

@@IanRushtonMusic we can't do in depth brain slice analysis on humans given soybean oil, that is why animals are used. Mice are few olive oil, lard, etc and ONLY soybean oil has these terrible effects. What are the chances that it somehow only works that way in mice and not humans? “If there’s one message I want people to take away, it’s this: reduce consumption of soybean oil,” Deol said about the most recent study.

[@IanRushtonMusic]

@@jaro6985 The claim that "ONLY soybean oil has these terrible effects" compared to olive oil and lard is an oversimplification. Different studies have shown various effects for different oils, and results can vary based on study design, dosage, and other factors. Animal studies are important, but assuming that effects in mice will directly translate to humans is not always accurate. There are numerous examples in medical research where promising results in mice didn't pan out in human trials. While the Deol study raises important questions about the potential effects of high soybean oil consumption, it's crucial to interpret it within the broader context of nutrition research. Single studies, especially in animal models, rarely provide definitive answers but rather just contribute to our evolving understanding of nutrition and health.

There is no baseline from which to compare because VIRTUALLY NO ONE eats a lower Omega 6 diet in any of these studies. The are NOT RCTs. Epidemilogical data with LOTS of uncontrolled variables.

You are wise to use butter instead of margarin. You may want to look up the historical uses of Olive Oil, for it was never used for cooking traditionally and we now know that is due to that unsaturated bond making it a mono and there for easily oxidized with higher heat as in cooking. Ironically, when you do do your research on that data, you will also discover that the historical Mediterranean's used Lard as their cooking fat. Better to use ghee, lard or my favorite, tallow.

[@182mehmetkoc]

You have looked into this in a completely wrong way. The reason seed oils are bad for you is not because they are unsaturated omega 6 fats. It is because they are heavily processed oils that are dangerously oxidized. They do become very toxic and lose all the nutrients they otherwise would have if they were say, cold-pressed. This has nothing to do with the fats themselves. If you can find a seed oil that is cold pressed and minimally processed, that would probably be not as bad just like you outlined in this video. However almost all seed oils that are used in foods today are extremely processed, oxidized fats that are terrible for you.

[@md82892]

That’ll still be problematic because any seed oil high in polyunsaturated fats will quickly oxidized and doesn’t matter if it’s cold pressed or industrially refined. What makes these oils dangerous is not only processing but inherent instability of polyunsaturated fat molecules. Brad is extremely ignorant and this video proved that he’s scientifically illiterate. All the RCT’s he is referring to uses extremely fresh lab versions of these oils and they’re not oxidized yet. When researchers looked at seed oils in normal storage conditions, they start to oxidize in 2hrs and within 12 months of storage their oxidation level reaches above 30%. These oxidized linoeic acid molecules damages LDL particules and causes oxidation on LDLs. In clogged arteries these oxidized LDL’s are found not the normal ones.

[@sasanegar]

There remains a few questions: - How about the exposure of seed oils to light in clear containers? - How about solvents like Hexane that are used in refining seed oils? - How about the comparison of consuming seed oils to EVOO?

This is a video about replacing saturated fats (and heat-stressed seed oils) with normal seed oils. YES, absolutely, replacing saturated fats (and processed foods with seed oils) results in better health outcomes, as has been well and long established. I was hoping for a video about the consumption of lots of seed oils vs replacing with olive oil or other fats like nuts, seeds, and avocados. I would also point out that seed oils make it incredibly easy to over-consume calories. 2-3 tablespoons doesn’t look like much, but you’ve just added 200-300 calories to that salad you’re eating or pan you’re cooking in. And those calories are effectively devoid of nutrition. So are seed oils heathy? Well, relative to what?

[@IanRushtonMusic]

You’re right to ask, 'relative to what?' Seed oils can be a healthier alternative to things like trans fats or highly saturated fats, which have been linked to heart disease. However, if we’re comparing them to whole food sources of fat like avocados, nuts, or olive oil, those options might offer more overall nutrition and beneficial compounds. It’s about balance and context-moderate use of seed oils, especially those rich in polyunsaturated fats, can fit into a healthy diet, but they shouldn’t be the only source of fats.

Lack of lower all-cause mortality despite a lower heart risk. It seems that cancer rates increase to even out the lower heart disease mortality.

i think asian communities have been consuming seed oils for hundreds of years...but they used to be cold pressed not ultra processed...and now in india we are seeing this slowly chainging to cold pressed especially wood pressed oils....

[@hutwarum]

Brad, the meta-analysis of studies with polyunsaturated fats improving diabetes and weight are fatally flawed. As u said, the study groups and the control (saturated fat) are both limited to the same amount of calories and carbs. But that’s not real life. Because a calorie is not a calorie if u can’t burn it for fuel. The body doesn’t want to burn the polyunsaturated fats because doing so damages the mitochondria. So the body burns sugar instead. So in the polyunsaturated fat group the sugar levels and therefore insulin levels of the participants drops. This seems beneficial to you in the study, but in real life this means people crave and eat more sugar. Which then makes them put on weight in the form of toxic visceral fat. Studies have shown that if u eat processed food with seed oils you will eat more. I don’t think anyone argues that that is not the case.

[@aenab.4596]

You can't judge seed oil by saying "if you eat processed food with seed oils". You added a whole other variable with the processed food. I use seed oils to sautee my home cooked, whole food, veggie, bean and wholgrain based meals. As seed oils have good health outcomes and they make veggies taste great, then there is a huge benefit for me to keep them in my diet.

[@IanRushtonMusic]

The idea that the body 'doesn’t want to burn polyunsaturated fats because it damages mitochondria' doesn’t align with established science. The body metabolises fats, including polyunsaturated fats, as an energy source when needed. In fact, omega-3 and omega-6 polyunsaturated fats have well-documented benefits for heart health, and mitochondria rely on various fat sources for energy. As for the claim that seed oils make people eat more, this might be more about the highly processed nature of many foods that contain seed oils. Processed foods are often engineered to be hyper-palatable, which can lead to overeating-whether they contain seed oils, sugar, or other additives. It’s less about the seed oils themselves and more about the overall quality of the diet. If you’re eating whole, unprocessed foods, even if they include seed oils, you're less likely to experience the same issues with overeating or weight gain.

[@arthureaton8]

What about the high temperatures that are used to extract the oil in the first place? Doesn't that break down the fats and produce trans fats?

[@Redranddd]

Now i have a cognitive dissonance, ¿what's the problem with junk food then? ¿The freaking microplastics?

[@DrittAdrAtta]

As explained - commercial junk food is cooked in oil that has been heated over and over and over again which degrades it, makes it oxidized plus trans fats are produced - those are harmful. At home, when you heat the oil just once and throw it away, there is no issue, you just simply abuse red meat, fats and carnohydrates without the additional toxic package😉

[@loganwolv3393]

Here's my take away: I think fast food places should switch back to saturated fats since yeah like you said reheating seed oils makes them harmful, so they may as well use saturated fats like lard or whatever tastes good. Now for processed foods that you find on shelfs and home cooking seed oils are still the healthiest option so we should stick to it.

[@u105524]

It's refreshing to see doctors educating themselves on nutrition as that is the root cause of so many illnesses.

[@MysteriousOoze]

The human heart uses fatty acids preferentially. Guess which kind of fat we evolved to consume for millions of years? Its not seed oils, that's for sure. Also look at the conversion efficiency of ALA into EPA - its 0.5 to 5%. We are not built to thrive on seed oils

[@AcesGaruda]

It reminds me of the absolute decades of studies proving that smoking is OK, if not good and healthy. Only when some people were for to look ar crying specific metrics, did some things become apparent. Same with seed oils.

[@rawbacon]

No one ever thought smoking was good for you and seed oils were in heavy use when I was a kid in the 70s and 80s yet there wasn't a fatty to be found. People that think seed oils are a major problem are a major problem.

Same thing with refined sugar, for decades they used the "it's just the calories" argument.

[@robertusga]

@Masterr59 it still is. You can lose weight just fine if you are in a calorie deficit while eating refined sugar. The best way to attain calorie deficit is to eat a nice balance of carbs, proteins and healthy fats, minimizing saturated fats.

[@Masterr59]

@@robertusga Refined sugar in place of those calories from nutrient rich whole foods has a larger negative impact beyond just the calories. This is why telling people to just count calories is still a very ignorant concept.

[@rainflowers1099]

I've seen elsewhere the suggestion that dietary fat can decrease insulin sensitivity. And that saturated fat is particularly bad for this. If you're on a carnivore or keto diet, this may be less of an issue in the short term at least, because of the lack of carbs. But if like most people, you're eating some mixture of carbs and fats, this would explain the inflammation from the saturated fat particularly. So swapping it out for polyunsaturated would decrease inflammation, and the risk of heart disease. But this doesn't necessarily mean polyunsaturated fats are healthy as such. Just more healthy than the saturated fats in terms of insulin sensitivity. And in the context of a common western diet, that may contain relatively high carbs. The key may be to limit fat intake as much as you can. And eat a healthy whole food diet, with some amount of exercise and natural sunlight thrown in.

[@tyrengertrud]

Yes, most seed oils and omega-6 PUFAs are not inherently problematic, and they can certainly be part of a balanced diet. Regarding the omega-6 to omega-3 ratio, I have a few points that need addressing/refinement: 1. You mention that a high omega-6 to omega-3 ratio is thought to cause chronic inflammation when discussing single cells, but this cannot be extrapolated. Could you clarify what you mean here? It’s important not to make this statement too easily without context. There is plenty in vivo evidence showing inflammation associated with high omega-6 to omega-3 ratios. 2. You mention that "The idea of modern diet full of seed oils and processed food has way more omega-6 to omega-3, which throws of the balance between these fats leads to inflammation". However, in the randomized control trials you mention, the comparison is between SFA and omega-6 PUFA intake. This has little relevance to the omega-6 to omega-3 ratio discussion. Of course, PUFAs are healthier than high levels of SFAs, but this doesn’t address the specific concern about the imbalance between omega-6 and omega-3. Comparing omega-6 to SFAs doesn’t provide insight into how the ratio affects inflammation; it’s more like comparing apples to pears. I believe the focus should be on how omega-6 excess, without sufficient omega-3, affects inflammatory pathways. 3. While you emphasize seed oils, they are not as problematic compared to the high intake of SFA from sources like meat, palm oil, or coconut oil, which are in fact what the trials you refer to compare. Excessive consumption of these SFAs also contributes to inflammation and other metabolic issues. What we need is less SFA and a better balance of omega-6 to omega-3. The emphasis should be on reducing SFA intake in parallel with balancing PUFAs. 4. It’s important to note that only a small fraction (1-5%) of omega-6 linoleic acid (LA, 18:2) is converted to arachidonic acid (AA, 20:4), which is the precursor for eicosanoids. Additionally, only 1-2% of AA is converted into eicosanoids. Most omega-6 PUFAs are stored in cell membranes as phospholipids, where they play structural roles rather than being used for eicosanoid synthesis. Cells can also redirect excess PUFAs into TAGs in lipid droplets, and this process differs between LA and AA. Therefore, it’s critical to differentiate between LA and AA in the discussion of inflammation, as their roles and effects in the body are distinct. 5. A similar point can be made for omega-3 PUFAs, as their conversion to EPA, DHA an eicosanoids is also limited 6. The omega-6 to omega-3 ratio IS important because the enzymes involved in fatty acid metabolism (elongases, desaturases, and oxygenases) are shared between the two pathways. High omega-6 intake doesn’t just mean more LA and AA, but it also slows the conversion of ALA into EPA and DHA, shifting the balance toward pro-inflammatory states. So it is a double effect. In the context of a modern diet high in omega-6, reducing omega-6 intake while increasing omega-3 intake is essential for restoring the balance and supporting anti-inflammatory processes. This does not mean that omega-6 should be substituted with SFA. 7. Pre-industrial humans typically consumed more balanced ratios of omega-6 to omega-3, often around 1:1 to 4:1. They ate grass-fed animals and wild game rich in omega-3s. Today, most conventionally raised livestock are fed grain and soy, which are high in omega-6 fatty acids. Pre-industrial diets also had a more balanced ratio because we consumed more leafy greens and wild-caught fish. So yes eating a lot of seed oils and processed food is bad, compared too eating more leafy greens, grass fed animals and fish. This is a VERY important point to make, when discussing this topic, so I am glad you mention this in the end, but I would have preffered you stretched this earlier. To sum up: Yes, the shift in our diet toward higher omega-6 is harmful, but it’s largely due to displacement of omega-3s in Western diet, not necessarily because omega-6 is used in moderation (like adding it to yogurt or salad). A high SFA to PUFA ratio is even worse, so it’s better to include omega-6 PUFAs rather than not enough PUFAs overall. Thus, our omega-6 to omega-3 FA ratio is off, but not due to eating seed oil, but due to eating to little omega-3 containing fats. Cheers, from a researcher in PUFAs

[@philliphartman2381]

The problem is that with processed foods where you find seed oils, you're also going to find sugar. So it's entirely possible it's the sugar causing all the trouble. However, in the real world, cutting out seed oils will also lead to a person cutting out sugar since they are found together and thus the strategy can work to improve health.

[@CharlieFader]

we can speculate about that. But there's also the issue that a lot of processed junk has palm oil in it. We can also cut out sugar or added salt and have the same effect, meaning cutting processed foods.

Lots of troubling issues that are potentially dangerous....or not fully covered here: 1) It was mentioned that seed oils ARE further converted to Trans Fatty Acids above ~200 degrees C... NEWSFLASH: Most restaurants you attend cook intentionally at HIGH heat ! 2) Omega 6 levels can escalate or build up in the body over time--humans do not get rid of them quickly. 3) What about Cancer ?? Places like Chipotle (supposedly healthy--not to pick on Chipotle's) FLOOD their foods w/ seed oils. You can't convince me this heavy, unnatural process use is healthy.

[@IanRushtonMusic]

While it's true that cooking oils at very high temperatures can lead to the formation of harmful compounds, including some trans fats, the statement oversimplifies a complex issue. The formation of trans fats depends on various factors, and not all seed oils or high-heat cooking necessarily result in significant trans fat production. And true, Omega-6 fatty acids can indeed accumulate in the body's tissues, particularly in fat stores and cell membranes. However, this accumulation is not unique to omega-6; the body also stores omega-3 fatty acids and other types of fats. It's true that Chipotle, like many restaurant chains, uses seed oils in their cooking. However, the term "FLOOD their foods" is an exaggeration. While oils are used in cooking, they're not typically used in excessive amounts that could be described as "flooding." Characterizing seed oils as cancer-causing or extremely unhealthy is not supported by current scientific consensus.

[@Nobody-Nowhere]

The omega6 theory is old, it was though that more LA meant more AA. But this did not happen, your body's LA to AA conversion is highly regulated. Even high amounts of LA omega6 were anti-inflammatory, and the higher LA blood levers correlated with lower CRC levels. You can refer to this paper : "Omega-6 fatty acids do not promote low-grade inflammation" November 13, 2017

You presuppose the seed oil in junk food is toxic which is not an established scientific fact. "junk food" refers to foods that are high in calories but low in nutritional value. While excessive consumption of any oil can be problematic, seed oils are not inherently "toxic" when consumed as part of a balanced diet. Factors that typically define junk food: high in added sugars high in unhealthy fats (particularly trans fats) high in sodium, low in fiber, low in essential nutrients, highly processed ,often designed to be hyper-palatable, leading to overconsumption. Even foods made with "healthier" oils can be considered junk food if they're nutrient-poor and calorie-dense.
