Are Seed Oils Inflammatory?! (The *Evidence* No One Shows)

"Seed oils are inflammatory!" according to every blog and podcast. But what does the science say? The evidence on 9 different seed oils, heated seed oils and genetic variability. A complete look at seed oils & inflammation and all the evidence you were never shown.
Are seed oils inflammatory?
1. seed oil on inflammation
2. Heated seed oil
vegetable oil is inflammatory? Only seed oils are inflammatory? Depends on omega6s, Linoleic acid?
flaxseed oil not inflammatory. omega3 rich, can be anti-inflammatory
canola oil: CRP didn't change
saturated fat vs omega 6s. replaced saturated fat with unsaturated fats (canola and sunflower). no change in inflammatory markers
one trial compared canola to olive oil, found a reduction in CRP on both canola and olive oil
similar to flaxseed oil. anti-inflammatory?
~1tbsp sunflower oil daily. refined oil, treated with chemicals and heated, not cold-pressed. no significant change to CRP
“n-6 PUFA may act as anti-inflammatory”

    I have been into Immunology, immunotherapy and recent 7 years gerontology and metabolic therapy Research work in Asia. Total of 18 years. We are currently looking at the Japanese diet and the new "Green Zone" of the pool of southern China centenarians. Similarly with rice and grains that have "new" rice or "old" rice, seed oils production and expiry date do contribute to its oxidation and rancidity impact especially in tropical S E Asia. The shelf life after opening the bottle is crucial in terms of using the seed oils for clinical trials. All these trials will start with a fresh new bottle. Individual consumption at home for casual stir-frying or deep frying means the bottle of oil can last for a few months. Rancidity if mild cannot be easily detected by an average person especially so if they are senior or elderly (slightly impaired smell and taste). Dining out has also one risk of having adulterated seed oils that are not fit for consumption. Traditionally, the Japanese 1000 years ago did not use seed oils but mostly boiled their foods using soup based cooking methods. Thank you Gil 👍💓👏for your indepth research and awesome contents. Personally, moderation in consumption and buying and storing small bottles (not large) are my advice to those who stlll want to use seed oils. 🥰

  • @rokzane

    @rokzane

    That's an argument for storing them properly and not buying more than you can use within 4-6 months. If they are stored in a dark, cool place, the oxidation is much slower. Under refrigeration, you get almost double the shelf life, and some under refrigeration (like nut oils, sesame, and canola) can last 2-3 years.

I am learning a lot about nutrition and I have to say oils are one of the few areas where I am totally confused whether it is good for me or not.

    They may have been small, but they were also consistently repeated in different demographic groups. That's a more significant point that lends validity to the conclusion that seed oils are at worst benign to the majority of the population but can also be protective. It's only under extreme conditions, like repeated high heat frying which causes damage to the oils that we really have to be careful with use. So if you want some fried food, make it at home!

    agreed, this was very well organized, and it's good he mentioned the longer-term studies, since some arguments against seed oils have suggested 8-12 week trials are not sufficient for any effects to measurably manifest. i avoid seed oils as a precautionary method (and also because they have no flavor) because omega-6 was not consumed in high concentrations in our ancestral environments--though the end of the video argues it's plausible our bodies nevertheless have a mechanism to maintain homeostatis with respect to the concentrations of resulting metabolites.

    Wow this must have taken alot of time, well done. I'm kind of dissapointed that so few studies specified whether the oil was refined or not, and that there wasnt many comparing seeds to refined seed oils. I think thats where the interesting part lies. I'm worried that most of the positive molecules you would find in these seeds are lost during the refining process, and removing them from their protective shell exposes them to oxidation. Really hope you are going to make all those other videos you mentioned. Oxidation, cancer, and heart disease (that one is definitely contentious). If you're not already knee deep in the research, Martin Grootveldt has some really interesting research on frying with PUFA rich oils.

    Not to burst your bubble, but inflammation is just one aspect of heart health. Something could increase plaque but not be imflammatory. Also, most of these studies are done on people who don't have diagnosed disease, so it's a bit less clear for those who do. I am not suggesting consuming oil is unhealthy, just that we don't have the data to really compare no oil diets with diets that do have oil (specifically healthier ones with predminantly polyunsaturated/monounsaturated fats vs. saturated). I personally follow a diet that is plant based and I don't consume oil in the house, but occasionally do when I eat out. I also have heart disease. So I don't think consuming oil at least occasionally is going to be a significant issue, but I also know that vacations and cruises in particular are rife with temptations and excuses, so I'd be careful. Just because you enjoy going on these doesn't mean you can't do them without oil, or without a minimal amount of oil if that's what has been prescribed. I've heard that cruises can be incredibly accommodating to almost any diet out there, and I've heard of people who don't eat oil asking for this on their cruise and being accommodated by lots of steamed veggies, cooked grains, beans, etc. As you probably know, there's no NEED to cook with oil, so a cruise chef should be able to do it just as easily as you (or your mom). I'm not saying this is necessary, and ultimately it's your or your mom's choice as to what to eat on a cruise, of course, but just know that it is possible and I would really ask them about this first just because you may be surprised at how accommodating they can be. Good luck!

I had purchased Caldwell Esselstyn’s book, reversing and arresting head disease and after a few months, they completely closed and healed. According to wound care, who is also part of the vascular team, she has an increase in blood flow to the leg. They were amazed because she had no surgery. Also, a year post stroke, she keeps getting better. She’s talking more and moving more, where she was completely paralyzed before. She had atherosclerosis in some arteries in the brain, maybe they’re opening up a little more too. I’ll continue to play it safe.

    Exceptional summary on these trials-one caveat, one could also hypothesize that the inflammatory markers used are not specific enough to the target organ which is usually the endothelium to identify a response one way or the other. For instance, hsCRP comes predominantly from the liver in response to cytokines secreted by the target process so is an indirect measure (but an acute phase reactant). Inflammatory markers like CTACK, MCP, HGF, Eotaxin, FAS, FAS-Ligand, and IL-16 might be more appropriate as being more direct and sensitive. Still a great overview-thanks.

    I wanted to add some info about heated fryer oils in the food industry based on my experience. When I was young I was a manager at a medium-sized fast food chain. We would fill the fryers with oil, and they would run at ~375F all day long, and we would change the oil every 2-3 days on average. I was later a manager at a grocery store with a hot food department, and had a similar experience - although we used the fryer less there so we only changed the oil on a weekly basis for the most part. Essentially, the more you fry, the quicker the oil starts to get filled with burnt sediment from the food. You can skim a lot of it out, but many particles are too small for the skimmer I guess, and eventually your oil begins to appear dark/dirty and can begin to affect the taste of the product, so you have to change it. I imagine at very well-run fast food franchises they have some very specific protocols, but where I worked, oil changes were based on a subjective assessment of the oil.

If it's not the refined carbs (sugar, grain flour), and it's not the refined oils, whether used for cooking or consumed directly, what is the cause? Is it a simple issue of consumption levels in terms of overall caloric intake and subsequent weight gain over time, as it is easier to over consume processed foods made with refined ingredients?

The current Cordioprev study has been coming out with some promising results. I've been very cautious about using oils in the past and have used olive and sesame oil only sparingly. It would be nice to have evidence that plant oils generally can be used without cardiovascular risk. Though coconut oil might not make the cut on this one.
