My soap box:
I bet that refined oils are not healthy. They aren't natural, require weird industrial/chemical processes, and only existed in the last ~100 years or so. Animal fat, butter, or unrefined coconut oil if you are vegan, seem to me to be the best cooking oils. These are mostly saturated fat, which you'll hear is bad for you. I've done extensive research on this and believe that this was largely a scam to get people to eat refined oils and grains instead of real natural fat which is mostly saturated fat. I haven't found any good evidence that saturated fat is unhealthy. And, I've been eating lots of it my entire life and seem to be in excellent health.
You would bet correctly. The whole "cholesterol bad, animal fat bad" thing originated from a vegan with an agenda, who also had enough credentials to make it look convincing, and here we are today. (Dr.Eades at proteinpower.com had a whole rant on the subject, knew the guy and watched it happen in realtime, but now I cannot find it.)
A good general rule is if you have to do more to the oil than squeeze it out, wash out the acids, and filter out the impurities, it's not good for you. Soy and canola in particular (in its first life, canola was an industrial lubricant) are questionable. Corn oil is probably the only "safe" seed oil, as it can be processed with mechanical pressure, heat, and water, and does not require other solvents. But do you know how the company produced it? of course not. Olive oil is just mechanically crushed, centrifuged, and filtered, but be aware that commercial olive oil of uncertain source may actually be mostly soybean oil.
Coconut oil involves finely crushing the meat and waiting for the milk and oil to separate, but using a solvent would be a lot faster, so I'd kinda want to know how it was processed.
Bah. Just use butter and other animal fats, all good. Just don't burn 'em, any burned oil becomes not good for you. My inner biochemist wishes to also note that animal fats are a lot closer to your body's required balance of fatty acids, too.
