>ghee Cholesterol oxides in Indian ghee: possible cause of unexplained high risk of atherosclerosis in Indian immigrant populations: https://pubmed.ncbi.nlm.nih.gov/2887943/ "Substantial amounts of cholesterol oxides were found in ghee (12.3% of sterols), but not in fresh butter"

> Indian ghee We have been using ghee in India for thousands of years. If immigrant Indians are having problems, they should look into what changed in their diet and lifestyle after they immigrated.

Indians in India have skyrocketing diabetes and obesity numbers in recent decades. 20+ years ago you would struggle to see a single non thin person.

Drastic increase in quantity of ghee (and sugar since a lot of Indian tests are a lot of ghee and sugar) consumed and reduction in labor (trading strenuous, perspiring work for air conditioned, sitting work) could be relevant factors that make ghee consumption from the previous thousand years not comparable to today.

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?

Be aware that all these oils contain a lot of omega-6, and very little omega-3 fatty acids. So if you consume a lot of that stuff, you also need a good source of omega-3 DHA/EPA (fish or supplement).

Also, there's quite a bit of controversy around the purported health benefits of coconut oil. Personally, I'm rather skeptical about it.

Yes, vegetable oil is typically soybean oil.

I went to the kitchen just now. Damn. So vegetable oils OTHER than soybean oil is fine for mice.

Slightly less damaging. High heat processed oils are probably not great in general.

Taking account that this is unproven in humans -- it's enough for me to avoid soybean oil, as cooking oil choice is not very important for my palate. That said, which oils would you use for frying and baking? Most high smoke point oils are, like soybean, polyunsaturated, so I'd guess that they could have some of the same (proposed) negative effects. Bonus points if the alternative is widely available (I see potential…

Humanity has been using Olive Oil for at least 1000 years. So that seems pretty safe to me.

Yes, but olive oil has a low smoke point and is not used for the same applications. Otherwise I'd happily use it for everything.

Wait, isn't coconut oil bad?

Well, it's mostly saturated fat. It's good for frying. Also not bad to rub on dry skin.

From the study: > One additional note on this study — the research team has not yet isolated which chemicals in the oil are responsible for the changes they found in the hypothalamus. But they have ruled out two candidates. It is not linoleic acid, since the modified oil also produced genetic disruptions; nor is it stigmasterol, a cholesterol-like chemical found naturally in soybean oil. 1. We're not mammals that exp…

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.

Peanut oil is most often recommended for Asian cuisine.

I currently use peanut oil, but it's still 30% PUFA. Presumably if PUFAs are bad (again, unproven!) then there would be something better.

Specifically for Asian cuisine, all the typically used oils are high in PUFAs. Otherwise there is EVOO.

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.

> olive oil is great but if you're frying stuff with it you're turning a lot of it toxic

Do you have a source on that? What is toxic about it? Really curious, because I cook a lot with olive oil.

Coconut oil is very high in saturated fats which some people may want to avoid.
