I noticed that almost all types of cooking oil (vegetable oil, olive oil, peanut oil, etc) contain some saturated fat. Since saturated fat is known to be a contributor to heart disease, then could you simply remove the saturated fats from the oil to make it healthier?
We tried that in the 90s, it went poorly: https://en.wikipedia.org/wiki/Trans_fat#History
I am not suggesting we add any additives, only to remove an existing fat from the mixture that makes up cooking oils.
It seems like the removing saturated fats part worked fine. They just messed it up by replacing them with trans fats which were even worse.
Saturated fat is good for you. Trans fats are the bad ones, those are unsaturated fats OR saturated fats that just become radicals. The cholesterol you get from eating is nearly nothing compared to the cholesterol your body makes out of sugar you overconsume.
My cholesterol has gone down to normal since I switched to an oil-less sugar-reduced diet. I use butter for veggies and lard for meats. Also, I only use whole-fat variants of diary.
It is generally recognized that high saturated fat consumption contributes to increases in LDL cholesterol. Trans fats are worse of course, but saturated fats in foods like hamburgers or ice cream are still a problem.
Interesting article on this: https://www.healthline.com/nutrition/5-studies-on-saturated-fat
Could it perhaps be that the hamburgers cooked in grease and butter and ice cream being loaded with sugar are the issues?
Grease contains a large amount of saturated fat. As for ice cream, added sugars are unhealthy too, but since a lot of other unhealthy foods don’t contain sugar we know it isn’t the only cause.
The 7 Countries Study, upon which the hypothesis that saturated fat causes heart disease was based, has been proven to be highly flawed and misleading. Ancel Keys intentionally left out the data from many countries that contradicted his claims. During the last 20 years many studies have come out showing there’s no correlation between saturated fat and heart disease, and pretty weak association between high LDL and heart disease. Obesity, insulin resistance and systemic inflamation are much higher predictors. And there’s a lot of information to suggest seed oils - canola and soy bean oils especially - are quite harmful.
Take a look at some of the studies saying saturated fat doesn’t cause heart disease. They are usually comparing the high saturated fat group to a group eating low saturated fat. Then you have to ask, what are they replacing that saturated fat with?
Often times, the subjects in these studies end up replacing saturated fat with equally unhealthy foods, especially salt and sugar. It’s no surprise then that they didn’t find any correlation to heart disease.
You will also notice that when the researchers specifically replace saturated fat with healthier foods like complex carbs or unsaturated fats, that the correlation suddenly appears.
To summarize:
Trans fat is the bad one and is even banned in many countries including the USA. It is formed as a byproduct when making many processed and fast foods.
You should get less than 2% of your fat calories from trans fat - preferably you should avoid them at all costs.
Saturated fat isn’t as bad as trans but it’s still not beneficial, the jury may still be out on exactly how bad it is, but it’s not healthy so it should be limited.
You should get less than 10% of your fat calories from saturated fat
Unsaturated fat is healthy, it’s good for you and it’s required in our diet as our bodies need it and can’t make our own.
A lot about health and diet isn’t understood very well. There are a number of advocates for saturated fats over PUFAs, with some (but not universal) evidence to support it. It’s entirely possible that it’s a case of correlation vs causation, but nothing has been proven with certainty.
I am so sick of this. Everything is bad for you, horribly sourced, unsustainable, promotes slave labor, has/is “evil” gmo. No one is in agreement and there is so much bad information out there and what info there is is buried behind a pay wall in a scientific paper i don’t know is there, and do not have the time or energy to decipher. The wealth of all human knowledge could be at my finger tips but the only reliable info are cat pictures.
It is really hard to do a good studies on diet. You end up with one of two conclusions: “Despite our best efforts we were unable to get our test subjects to follow the required diet”; or “These results may not generalize to the general population who isn’t confined to [a prison cell/hospital bed]”.
We can study how one meal effects your body, but that isn’t really helpful - Does it matter if some diet causes cholesterol to go up/down for a bit and then it returns? And cholesterol is one of those markers where we have enough studies to conclude that high is bad, but that doesn’t necessarily mean that high for a bit and returning to low is also bad. Some things like smoking are such large effects that we can look at general population and make conclusions, but often the effect isn’t that large and so it is believed that some diet is good/bad, but we cannot prove it from data we can collect.
The above is about actual science. Most mainstream diet books at best cherry pick some fact and then take it to an extreme to create some eating plan ignoring all evidence of other facts that might limit how far you can take this one. (that is assuming they start with a fact - just making up facts is common as well) The news media doesn’t care to figure out what is real science and what is made up facts.
Right, but a concrete “we don’t know” from a source that is the end all of what a study finds is needed. Because right now everyone and their mother is a arbiter of the “truth” corporate interest and idiocy have choked all reputable data to death. You can not rely on journalists to interpret studies, as their motivation is based on money one way or another. Obviously there is a problem with corruption when that authority is centralized but right now either ignorance or malice is a given
Well the “promotes slave labor” and “horribly sourced” are not limited to food, and GMOs are fine.
Diet is definitely one of those things that’s really hard to research though, because people are peddling snake oil constantly. I wish i had a solution.
Snake oil is the only healthy fat and should be consumed in massive quantities.
Maybe stop looking for people to tell you what to think, read the info first hand, at the source, and make your own conclusions?
It’s not really bad for you; it only depends how long past about 30 you want to live. Evolution only cares to where our children could mostly live on their own, and then we were valueless.
The rest has to be done with diet, exercise, and using our brains to extend our species’ lifespan.
But yeah: go crazy. Don’t get vaxed, don’t wear seatbelts. Don’t eat as well as you can, don’t work the heart and the joints and the muscles, don’t foster and build relations for a strong community that cares for one another, don’t contribute to education and medicine and safety and enrichment. You’ll be fine…
… until just after your evolutionary best-before date of about 30, if you did nothing to extend that.
I mean, I’m not concerned so much about what evolution wants. I am more concerned that i can make living not suck.
I feel like my calorie tracking app is really harsh about saturated fats
It gives a D grade to even the tiniest bit of coconut
Might be because fats are very energy dense. They net about 9 calories per gram. However, if the app is only tracking calories without context, it is going to miss calories-over-time and satiety. Fats tak longer to metabolize and tend to be good at triggering and maintaining feeling sated.
According to this article, It is generally recognized that high saturated fat intake is associated with heart disease.
I’ll chime in what comes to mind, since people don’t really talk about the technicality here. I’m not sure how much is common knowledge and how much is more specific information but just some thoughts.
One of the first things that you should keep in mind is that “saturated fat” is not a very specific description. It is a colloquial term for saturated fatty acids. In (cooking) oil, these are predominantly found in a form called triglycerides. This is a glycerine backbone with three fatty acids that are connected via a covalent bond. So it is a molecule, not some loose attachment. (There are free fatty acids, but they are usually removed in raffination, since they are bad for quality. There is even a specific value that measures the content of these free fatty acids in oil, the higher, the worse the quality.) A triglyceride therefore looks somewhat like ‘-,-’ with the vertical lines being the acids and the - being the backbone. Depending on the acids, the molecule takes .ore or less funky stereo shapes.
There are many different saturated fatty acids, monounsaturated, polyunsaturated fatty acids. They come in different lengths with the “unsaturation” at different places. If you take a specific oil - i.e. peanut oil - and look up its content you will find percentage ranges of different fatty acid or triglyceride contents. Because every batch of every oil is a new mixture with different contents of fatty acids and also, and especially, different triglycerides. A lot of it is stochastic, but there is some logic in that. For example, the middle position tends to be an unsaturated fatty acid, the outer ones saturated. Or sat-unsat-unsat, if you really go for it. Yes, there are triglycerides containing only saturated fatty acids. (MCT are actually quite popular for different reasons.) But mostly it is a mix. I’m not even sure if there are triple polyunsaturated fatty acid triglycerides, I think these are rare in natural oils.
Now, to remove all the saturated fatty acids, you would have to do harsh chemical treatment on all the triglycerides and actually split the molecule. You can do this, among other methods, by making soap, or making fatty acid methyl esters. Then you can remove all the saturated fatty acids. And then you can use the others to rebuild the bond with the glycerine. (You can, in theory, also make specific combinations of fatty acids in triglycerides. But we are talking about lab grade stuff here.)
Most people who want a healthy oil would not want this kind of harsh chemical treatment of their oil (think virgin olive oil). But apart from that: a triglyceride made solely of (poly)unsaturated fatty acids, let alone an oil made of these, would be not very stable or usable. Apart from maybe unfreezing small amounts and then using it in a salad you would hardly have any use for it. I also cannot, for the love of God, imagine the taste. The type of fatty acid and its position in the molecule largely determines the physical behavior of oils and are not just contributing, but basically creating quality aspects such as mouth feel, lightness, melting point or crystallization. Your best bet would be to make a supplement with that, not to use it as an actual ingredient in food.
Finally, this perfectly answers the question I had. Thank you!
I think the cost/benefit ratio is the main issue. Splitting oils to remove the saturated fat is not a simple process, especially when the easier answer is “use an oil naturally lower in saturated fats” like rapeseed (canola).
You don’t think they could market it as a healthier oil and sell at a higher price?
Eh I think they’re two different markets. If you prioritize health over taste, go for the cheaper, natural rapeseed. If you’re prioritising taste over health, most people are not going to be bothered by the sat fat, and would prefer an unadulterated flavour.
I believe you have to distil the oil, so it’s definitely going to be heated. You can be sure that the processing required to remove the sat fat is going to change the flavour and texture, while also somehow making it worse for you than either.
I think the point is those oils already exist and are cheaper than refining other oils.
[Insert doubt.]
We probably could, but I think it would be a lot of effort for a relatively small gain. If you’re concerned about saturated fat intake, the most effective thing to do would be to cut back on meat and dairy products, since those are much more potent sources.
I’m no dietician, but I can’t imagine cooking oil makes up a significant portion of saturated fat intake for most people, when you consider the popularity of dairy in all its forms in western cuisine.
no thanks, I prefer unrefined oils
If you want to live a perfectly healthy life, your food will be a paste or shake devoid of all enjoyment.
Life is finite and food that is enjoyable will never lead to a healthy life. I’ll take the bacon over the misery of a life that ends in a bullet.
People who think like this, miss two important points in my opinion:
-
If you have a dogshit diet it’s not going to be a “happy life full of tasty food” it’s going to be an absolytely miserable existence, filled to the brim with stomach problems, skin problems, awful sleep schedule, variety of diseases and feeling bad in general
-
You don’t need a nutrient paste to eat healthy - you just need a balanced dier. That means that shouldn’t eat absolute garbage and not “overconsume” anything. Eat veggies, dairy, treat yourself to meat once in a while and you golden. The only actually hard thing it requires is some work - you need to actively seek recipes, spend some time at the store to find good products or even spend some time to find a good local shop that actually sells food and some processed garbage from supermarket, and eat mostly cooked at home stuff.
But for me personally it is worth it. I would much rather eat some backed veggies with a glass of milk and tasty fruits for a dessert in the evening, than go to a dirty cramped place and eat shitty cardboard-like dog food that they serve at McDs
I will add to this that WORST case if you just eliminated fast food and Soda / fruit drinks you’d almost automatically be eating healthy.
I don’t eat like a rabbit, but just not indulging in the bottom tier garbage keeps me heathy while still enjoying my food.
I will agree with OP that there is a threshold where you try to eliminate every single bad thing where it just becomes exhausting and hinders enjoyment of life. But that’s way down the line.
Start without McDonald’s and Coke and see where life takes you.

Well said. Quality over quantity I always say.
Lobbyists
That could be true for meat and dairy industries but I fail to see how removing saturated fat would be a threat to Big Vegetable Oil.
