Can someone please talk to me about which oil I should be using for different types of cooking please??

[cherryboomboom]

I am getting really about this!

I always thought that olive oil was the best oil to use so use this all the time for everything with exception to deep frying (which doesn't happen often).

But now I have heard that it is ok for salads, breads anything where the oil won't get hot because that then causes something to break down and then it ends up bad for you? And then someone else told me that coconut oil is the healthiest oil??
So what should I be using for the following examples:

gentle frying (browning meat/onions, omlettes)
cakes (carrot cakes etc.)
Roast potatoes
Roast veg
Stir frys

Any other examples please as cannot think of any more!!

lol @ unclassified. That's the sort of thing my mil would say. Semi-skilled milk etc.

Here's a handy comparison chart.
