Home cooking is generally going to be better than particularly fast food because you are not reheating the same oils over and over.
Coconut oil is generally held as better. Cold pressed oils otherwise. Prepare to pay more for them. Be aware that food packaging labels have been known to lie about oil origin. Basically, fewer steps between growing the food and your mouth the better.
Preparing food at home is going to reduce a lot of the processing and reprocessing that happens to commercial packaged foods. I think that's going to be a net win.
Maybe get a feel for exactly how much oil is required and keep it to a minimum.
When I was using pans with a non-sticking coating, I used very little oil.
Now switching to cast-iron or carbon-steel I noticed that the best point to cook the food is to add some oil to the pan, wait for the oil to be heated properly, and only then start adding the food. Of course, I still add very little oil (maybe 1-2 tablespoons) but compared with non-sticking pans it is yet a visible thin film.
I am currently using extra-virgin olive oil but I am not sure it is good. Now I understand that instead of focusing on "extra-virgin" label I should focus on the process used to produce the oil.
On the other hand, sharing here a bit of anxiety I am no sure what to eat:
- On one hand I could try to eat more non-processed, non-cooked food like salads, vegetables ... But the risk there is being contaminated with various pesticides. So I am a bit concerned to switch to a diet mostly based on this as it means to increase a lot the quantity of such food
- On the other hand, cooking using what people consider healthy cookware means (so far for me) using some oil which I now get should be limited
- There is also the idea of red meat being bad, but also fish having mercury or radioactive elements. Probably not all of them but after reading this kind of information, I am a bit more aware of buying fish as I don't know exactly which one can be contaminated and from what area.
- The chickens seem also be not be healthy (don't remember where I read this and I somehow suspect it is false).
So I am really a bit puzzled about what to eat.
I don't think there is an easy answer.
Probably the correct answer is to grow my own food. But that is another style of life.
If you rinse vegetables well most pesticide residue will be removed. Also, some vegetables that are peeled remove that exposure route as well.
There are studies showing some kinds of organic products are worth buying because of the reasons you mention, but others are not.
I think the more you can buy food that you trust the better. This doesn't mean growing your own, it means learning more about where your food is coming from and the chain of producing and selling it. It may mean going to smaller shops, more trips, farmers markets etc. It may just mean reading about brands etc.
I think many people are wrestling with similar questions as you; you're not alone.
Using saturated or monounsaturated fats or oils are your best bets for sauteing. You can also braise things, in some kind of liquid.
Not the use of oil to avoid sticking is the problem, but eating it after that.
Besides choosing a kind of fat that is less sensitive to temperature, as described in another answer, when possible you should try to clean the fried food of the frying oil and to throw away most of the used oil.
