Here in Sweden, however, it's easy to find and buy organic cold pressed rapeseed oil. I'm of the impression that this stuff is a lot better for you than "canola" oil.

I'm not sure how you reach that conclusion.

Or, was my parenthetical comment about high heat cooking with olive oil confusing? I was speaking of canola/rapeseed oil when I said the evidence that it is healthy have all but evaporated. Olive oil is great, but burned oil is carcinogenic. Olive oil burns at a quite low temperature. So, cooking in grapeseed oil is probably a better bet, and adding olive oil toward the end for flavor.
Canola, or rapeseed, oil is somewhat less certainly good for you. And is quite low in saturated fats; which is why it became so popular. It was a low saturated fat alternative to higher saturated fat oils. That was probably a premature optimization...a variable was optimized before the full effects of diet were understood. Grapeseed might be a healthier alternatve to rapeseed oil for high heat cooking (olive oil has too low of a smoke point for any serious cooking, it's more of a finishing oil, if you care about your health). I skip it, along with corn oil and soybean oil. I don't know that it's unhealthy, but I've been seeing evidence that it might be for a few years now. The evidence that it is more healthy than other oils has all but evaporated, however, so there's no reason to choose it over cooking oils that have more recent and convincing evidence of their effect on health.
