Sunflower oil has even higher PUFA content than soybean, which is presumably the cause of these health issues in mice. I believe soybean was just chosen for the study because it's extremely ubiquitous in the US. edit: Partially wrong! I'm told above that high oleic sunflower oil has a different profile with less linoleic oil, and apparently it's becoming more common: https://www.nutritionletter.tufts.edu/general-nutr…

Besides traditional sunflower oil, which contains mostly linoleic acid (a PUFA), now there is "high oleic sunflower oil", which is extracted from a variety of sunflower initially developed in Russia some 50 years ago, but now grown in most countries. This non-traditional sunflower oil has little PUFA and it is perfect for frying and baking. The sunflower variety grown for high oleic oil has a genetic mutation with th…

Oh, I updated my comment for someone else's brief reply then you popped up with the full rundown. Thanks!

The detail about forcing genetic mutation is neat, will have to read up on that.

My understanding is that most of the oils we use are unhealthy. They are highly processed and inflammatory. The good oils are avocado oil, extra virgin olive oil and coconut oil. Is this correct?

It's more nuanced than that but you could do a lot worse than that list. Fat profile matters, and smoke point matters, e.g. olive oil is great but if you're frying stuff with it you're turning a lot of it toxic; avocado oil is better for high heat.

There is no scientific evidence that olive oil breaks down into toxic components.

Go try and eat only coconut oil for say, 2 weeks, you'll feel the difference.

The heck is this? Eat a pound of coconut butter a day? Eat more than a few tablespoons of any edible oil in one sitting and you'll definitely feel a difference. Edit: using only added coconut oil in cooking is, upon reflection, a more probable interpretation. Sorry.

MCT oil made from coconuts.

You can mix it in with things like coffee and shakes, easy way to get it.

I used to eat sardines every day trying to get the health benefits of fatty fish. They were packed in soybean oil. I drank the oil too. With time I began to have bizarre mental issues that I finally tracked down to the sardines. Sardines packed in olive oil don’t cause this issue. That’s my anecdata to share.

Maybe that was oils in general? Eating too much cooking oil makes me feel like absolute crap mentally, regardless of type.

Obviously the syndrome described in article is possible in your case, but the article sounds like a chronic accumulated damage thing, not an acute reaction just after eating.

The three oils/fat I have been taught to use in my Indian kitchen are: sesame seed oil, ghee and coconut oil. Sesame seed oil because it has a high smoke point. Ditto with ghee. The choice of oils always has to do with smoke point and hence what we use it for in the kitchen. [..] Sesame oil is full of antioxidants. Along with vitamin E and phytosterols, it contains lignans, sesamol, and sesaminol. These compounds hel…

Olive oil is not harmful when heated! Please link to scientific research showing this.

Here is one of many studies showing the opposite: https://www.sciencedirect.com/science/article/abs/pii/S02786...

It's a very German thing to not use olive oil for frying. It took me by surprise when living abroad, and to realise it's a common frying oil in Mediterranean countries but also in the UK.

Economics, probably -- sunflowers and canola grow more easily. Olive oil is a nice pan-frying oil, it's what I use. Linguistic thing: When Americans talk about oil for frying, in my experience, they are a fair bit more likely than us to specifically mean deep frying, for which olive oil is no use. Way more of a deep-frying culture, from several different influences. American cooks are slightly more likely (than the B…

“Broiling” would refer to using the broiler on one’s oven, I’ve never heard that term used to describe pan-frying. Terms I have heard are sautéed and seared

Soybean oil has less partially hydrogenated oils than other deodorized oils, making it potentially the healthiest of the deodorized oils.

Obviously deodorized oils are not very healthy, but I honestly don't understand all the posts like "Eat only coconut oil/butter/lard". For the "appeal to science", there's plenty of data that diets very high in saturated fats is a risk factor for heart disease. For the "appeal to nature", ancient peoples did not have our modern access to animal fats, hunter gatherers ate a lot of seeds, nuts and bugs to fill out a diet that otherwise ate small lean game with occasional big fatty hunting successes.

>Coconut oil is the least fattening of all the oils. Pig farmers tried to use it to fatten their animals, but when it was added to the animal feed, coconut oil made the pigs lean [See Encycl. Brit. Book of the Year, 1946].

There is plenty of research done on the harmful effects of seed oils. It’s not a stretch to assume this is yet another study demonstrating this in mice models.

But there also seems to be a ton of research suggesting the seed, nut and legume consumption is very healthy...

Yes however that’s different than consuming processed seed oil.
