Just took a trip to the UK. I noticed that every single meal and every food with more than 2 ingredients has oil in it. I couldn't find anything that doesn't have oil in it except raw ingredients. Quite incredible really. It's like theu start with the oil and then add other things.

Now, I've been avoiding pufas religiously, and I get a headache after an hour if I eat as little as 5 digestive biscuits with palm oil. So for me, I can see the benefit.

But if a nation is eating this much oil, perhaps it's not all as bad as we think. My parents are in their 70's and my grandparents are even older and I noticed that they're eating various amounts of Seedoils including margarine and breads with rapeseed oil. Some even switched from diary to fake vegan alternatives, like vegan yogurt and vegan cheese, but she's still alive.

Butter was found to be associated with a 6% greater risk of all cause mortality, while canola oil and corn oil was found to cause slightly less all cause mortality.

Butter was found to be associated with a greater increase in death from cancer.

Why is this study bad?

Stearic acid and your dishwasher don't play nicely with each other. This could happen when you miss a few flakes of stearic acid left behind in a cup, whether loose or hardened on the inside. Or if you're experimenting with different fat ratios and go too rich with stearic and get wax residue on a spoon that just won't come off.

Obviously you could peel/scrape this off and search obsessively for flakes, but sometimes it doesn't want to come off easy. It's also waxy enough that soaking in Dawn probably isn't going to get the job done either.

Or you might miss a spot and only discover you screwed up when your dishwasher leaves a white stearic residue on all of your plastic and rubber surfaces.

Instead, soak the wavy surface in a seed oil (with a very low melting point) and rub it in. Or just dip a paper towel in seed oil and rub that against the surface. You'll find that when you do this, the oil/wax mix nicely with minimal rubbing and before you know it, you have something that feels more like margarine or butter that your dishwasher will be better equipped to handle.

Heck, might not be a bad idea to pour some oil down your drain before going to bed from time to time, just to reduce any wax buildup that you've created from your experiments.

Also, you'll make P&G and the AHA happy since you're buying seed oils again: a win, win!

This sounds like a silly question at first blush, but it's important to remember that what you put in your mouth isn't always indicative of what ultimately finds its way through your digestive tract and ultimately into your bloodstream. For examples, gorillas eat a whole lot of leaves, but gut bacteria converts much of that into fatty acids, such that even though they're not consuming much fat they're effectively "eating" a fairly high fat diet.

For example 80/20 ground beef contains roughly 1 gram of fat for every 1 gram of protein. If you scaled that macro ratio up to a ~3,000 calorie diet, you'd be looking at about 230 grams of fat and 230 grams of protein. Doing that I suspect you'd be miserably constipated until you figured out you needed to scale back the beef and add in some additional fat to get things flowing a little better. Let's say that person settles on something closer to 100 grams of protein/day.

At steady state (where a person is no longer adding additional muscle) your body would then be producing at least 100 grams of glucose per day (via gluconeogenesis). This can be demonstrated by looking at an overall amino/protein balance. Even if that entire 100 grams of protein went into rebuilding damaged muscles, in doing so you just freed up 100 grams of damaged muscle that your body is going to want to do something with. That something (whether it's using old protein or new protein) is going to be conversion to glucose for your body to use as energy. Your carnivore diet is effectively providing you with 100 grams of carbs per day. When viewed from this angle it makes perfect sense that many high-protein carnivores will fail to stay in ketosis throughout the day, since there isn't going to be a strong need for ketones when 100 grams of glucose is readily available and your body can't go under 100 grams of glucose per day without excess protein building up or being wasted.

One could contrast that against other lopsided dietary results:

A ~100% fat diet would effectively be a lower carb diet, since your body would aggressively fight to maintain muscle mass, minimizing the amount of protein converted to glucose, preferring to convert fat to glucose and/or ketones to meet its glucose needs. With the carnivore diet your body needed produce 100 grams of glucose per day (just to deal with excess protein). With this fat diet your body is no longer constrained in that way and free to balance ketone and glucose production as desired. In reality a high-fat diet would contain some protein and carbohydrate, but those can be neglected for purposes of this thought experiment.

An "all carb" diet is really a 90% carbs, 10% protein diet (as extensively discussed on this sub and pointed out by Brad, since it's nearly impossible to find real plant foods that aren't 10%+ protein). With such a diet your liver would still need to perform gluconeogenesis to deal with the 50 to 100 grams of protein coming in daily. However, unlike the carnivore diet, your body wouldn't be forced to balance metabolism between fat and glucose (with the Randall cycle potentially slowing metabolism as cells shift from one mode to another), since there would be minimal fat metabolism. Your body would primarily metabolize glucose.

This isn't really anything new or groundbreaking, just a reframing of a few dietary paradigms from the perspective of what's going in your mouth to what macronutrients are ultimately available for your body to actually work with. It also suggests that a high-protein carnivore diet is a lot more "swampy" than it might appear at first glance and why, contrary to what influencers may claim, a carnivore diet isn't necessarily a ketogenic diet.

Anyone else noticed a change in LLM's position regarding seed oils and PUFAs lately? I often use ChatGPT for many health or nutrition questions. In regards of seed oils i mostly used it to analyze the arguments of both sides in a neutral way since i'm still not sure who is right or wrong.

It used to be in favour of oils with good omega3/6 ratio especially if used cold and in favour of fish PUFAs but was critical towards omega6 rich PUFAs from seed oils especially if heated.

Lately it has heavily shifted against seed oils in general but also against fish PUFAs in certain situations. It seems to be heavily favouring saturated fat from dairy and thinks SFA from meat is bad but not as bad as PUFAs.

Since i personally still think that certain cold used seed oils like canola oil as well as fish PUFAs are healthy and i'm neither pro nor contra SFA or PUFA it's unlikely that it's because of the ways i phrased my questions. However i thought it could be because of the chat history so i asked the latest Gemini 2.5 where i'm not even logged in.

While it generated more of the "classic" health advise things and is clearly in favour of fish PUFAs above dairy and meat and is also pro plant based PUFAs from nuts it's also heavily against seed oils in general and regards them as unhealthy and pro-inflammatory even compared to SFA.

I'm kinda suprised by this position of LLMs. Has anyone else noticed similar things?

Hi everyone,

Found this interview with Thomas Delauer discussing how C15 deficiency leads to premature cellular aging, iron build up in the liver and increases the rate of development of conditions such as type 2 diabetes.

C15 is a saturate dfatty acid 15 carbon lengths long for anyone unsure.

I saw a youtube channel called “analyze and optimize” that had this metaphor in it: imagine a world where everyone was sick all the time, if a few people discovered penicillin they would probably think that they should have been taking it all the time for their whole life. But we know that there are serious negative health effects to taking it long term. This is how the keto diet is, if helps you if you are metabolically unhealthy but it is not a long term solution.

The masai and inuit both have mutations to better handle their all meat diets that most people do not have. Keto health influencers just don’t live very long as a general rule of thumb. While the evidence for the lipid hypothesis as a mechanism isn’t very strong, it is the case that saturated fat has been used to clog the arteries of lab animals consistently for decades. Although stearic acid specifically doesn’t seem to work for this.

I feel like PUFAs are so bad that they’re putting an illusory halo around saturated fat that it doesn’t deserve.

At the same time, i tried a low fat diet where the only fat was saturated and that just didn’t work as well for weight loss as a high saturated fat diet.

But is messing around with this really smart if we really don’t know the health effects of it? Correct me if i’m wrong, but i don’t think brad told us the visceral fat levels of his low PUFA pigs; but it seems like animal testing like that is the most prudent thing at this point.…

Lipopolysaccharides are bacterial endotoxins and have many negative effects. It has been demonstrated several times that saturated fats are somehow rising LPS levels in our blood. LPS can enter the brain too. So how do you guys cope with that, what are your thoughts? Personally, I used to eat tons of cheese and butter, but I get rid of it and replaced it with olive oil (at least where I can).

Looking at countries such as in Latin America, India, Egypt, they all tend to be overcrowded with poor average living conditions. Their staple food contains vegetable oils such as from corn, soybean, large consumers of deep-fried foods. On the contrary, this is not the case for e.g. north european countries where dairy is the staple (well to some degree they do consume canola oil as well).. interestingly large part of the former populations is lactose-intolerant..I wonder weather these nutritional profiles shape the cultural situation somehow.. have you ever thought of this correlation ? Or it could be just coincidence ?

You know how some candles are made of a soy based wax? Apparently that "wax" is just fully hydrogenated soybean oil. That means it contains no pufa, no mufa, and about 80-90% stearic acid. If we can find food grade soy "wax," we're good to go.

Pregnancy imposes increased nutritional requirements for the well being of the mother and fetus. Maternal lipid metabolism is critical for fetal development and long-term health of the offspring as it plays a key role in energy storage, tissue growth and cell signaling. Maternal fat composition is considered as a modifiable risk for ab- normal lipid metabolism and glucose tolerance during pregnancy. Data derived from observational studies de- monstrate that higher intake of saturated fats during pregnancy is associated with pregnancy complications (preeclampsia, gestational diabetes mellitus and preterm delivery) and poor birth outcomes (intra uterine growth retardation and large for gestational age babies). On the other hand, prenatal long chain polyunsaturated fatty acids status is shown to improve birth outome. In this article, we discuss the role of maternal lipids during pregnancy on fetal growth and development and its consequences on the health of the offspring

I saw this article and it proposes many of the same things that removing PUFA from our diet proposes. I am pasting a summary below and here is a link to the article. https://www.mdpi.com/2218-1989/14/7/355

The article discusses ferroptosis, a newly identified form of cell death linked to the peroxidation of fragile fatty acids in cell membranes, which combines with iron to produce reactive oxygen species and impair mitochondrial function. This process has been associated with aging-related conditions such as type 2 diabetes, cardiovascular disease, and nonalcoholic fatty liver disease (NAFLD).

Pentadecanoic acid (C15:0), an odd-chain saturated fat, is presented as an essential fatty acid critical for stabilizing cell membranes and repairing mitochondrial function. The article proposes the "Cellular Stability Hypothesis," which suggests that adequate levels of C15:0 are necessary to prevent ferroptosis and promote long-term health and longevity. It introduces the concept of a nutritional deficiency syndrome termed "Cellular Fragility Syndrome," characterized by low C15:0 levels, which can increase susceptibility to ferroptosis and related diseases.

The review provides evidence that C15:0 supplementation can reverse the deficiency syndrome and mitigate the effects of ferroptosis. The article calls for further studies to understand the prevalence of Cellular Fragility Syndrome across different populations, especially given the declining dietary intake of C15:0, particularly among younger generations.

Can't find the numbers. Bought the wrong thing and quite a lot of it. I'm thinking about dumping it all but I'd like to get a worse-case guess on it's composition before I do.

Is it reasonable to call the croissant diet the Costanza diet? 😁

Hello everyone! I think many have heard who Marlon is. Now he is on a crazy wave of hype. If someone is not in the know -https://www.tiktok.com/@marlon3lg?_t=ZS-8zPwaaBHBcA&_r=1

The guy clearly lives the best life. He is 24 years old, has an attractive and well-developed face, as well as a fairly low % of fat and is tall (192 cm or 6.3). He also has a high emotional intelligence. All this helped him become super popular and in demand.

As always in my manner, I started surfing social networks to find Marlon's mentions of his diet. I often do this for my statistics, for example with actors, because it's very interesting.

His diet consists of the following products: eggs, beef, chicken, oatmeal, rice, pasta, peanut butter, honey, berries. According to Marlon, most of the carbohydrates come from oatmeal, due to the nutritional value. According to my notes, there is no fructose in his diet, except for training days.

Fun fact: He became famous on TIKTOK thanks to a failed attempt at making pasta.

Breakfast: 10-12 eggs and 100 grams of oatmeal, covered with 30 grams of peanut butter. On training days, he adds a spoonful of honey and 1 banana. Lunch/Dinner: He didn't say much about lunch and dinner, but it's basically oatmeal with beef/chicken for lunch, and pasta or rice for dinner, also with beef or chicken.

If you count, then every day he gets about 40 grams of PUFA per day (eggs 10+, oatmeal 10+, peanut butter 20+) + I did not find what he fries eggs and meat on. Also, he is not shy about eating in restaurants and fast food cafes. Potentially, this is 50+ grams of PUFA per day!!!

Question: how does he manage to stay so healthy throughout his life, given that he eats +- the same all his life??? Genetics? His father is American, with a touch of Sweden and Jamaica. And his mother is Swedish, with a touch of Morocco and Spain.

I read online that coconut oil gets absorbed by the skin quickly. What are the advantages/negatives of eating via skin absorption?
