What bothers me about canola oil is it is actually rape seed oil. Rape seed is/was originally toxic. I have heard two different stories on how this was overcome. 1) The toxicity was bred out by Canadians. 2) The toxicity is removed in a process invented in Canada. In either case Canadians are responsible and came up with the more marketable name. Imagine trying to sell rape oil.

I worked on a farm growing rape seed in Germany and once slept on the side of a rape seed field outside Malmo, Sweden on summer solstice night, a very short night.

I've also noticed a movement renaming to canola seed. Yeah, some people need a new name for everything.

I think it's higher polyunsaturated fats are what concerns me the most

According to whom, and by what metrics?
