I do use a non-stick spray too, sometimes plain oil or butter just aren't enough, especially with baking. I have a can of President's Choice Too Good to be True "The Virtuous" vegetable oil spray here, and it contains : canola oil, lecithin and propellant. (isobutane, which evaporates quickly)

The nutrition data says a 1-second spray has 9 calories, 0 gms prot. or carb. and 1.0 gram fat, comprised of 0.3 gm polyunsaturates, 0.6 gm monounsaturates and 0.1 gm saturates. That leaves no room for trans-fat, which means it's not hydrogenated.

I don't like the smell of the propellant either, I always spray way far away from my face!! Anyway, there is a choice, but you sure do have to read the labels.
