Peanut oil is used pretty extensively in GA, the state, and I tend to love the flavor it imparts. I'm curious how it sits on the healthiness chart. My gut feeling is that it's somewhere above canola but below avocado.
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 personally use avocado oil for anything that peanut oil would be useful for (like high-temp cooking).
