Fats in newsletter

I loved the article in the newsletter on fats, but just wanted to clear up something.

We do eat a bit of butter, because there are times when only butter will do!! But I'm unsure what is the best to buy. It's good to have one that spreads from the fridge but does anyone know a good one that doesn't have margarine in? I just bought one with canola oil in but wasn't sure if that was a good fat or not?
