I've been doing some research into oils recently, skimming the boards here, and I notice a disproportionate number of posts saying things like "Don't use Canola oil, it is the devil" etc.
Most of these posts make some kind of vague assertion without any backup, some of if fairly ludicrous (canola oil is made from rape seed, rape seed was used to make mustard gas, hence canola oil is dangerous like mustard gas, etc).
I just want to know what the problem is, and -if- there is a problem, can anyone point me to any research (actual science, not vague assertions by some health guru) that indicates there is anything actually wrong with Canola oil.
To summarize the negatives:
1. Rape seed has some toxic components. (but to my understanding, Canola oil's processing completely negates that)
2. Canola oil creates free radicals at high temperatures. (is that true? and if so, can someone show me any research that actually shows a negative effect of those levels of free radicals on humans?)
3. Canola oil can taste nasty at high temperatures. (fair enough, although I haven't had the problem in my own cooking).
From where I am sitting, it seems to be a pretty good source of Omega-3s and healthier than animal fat.
Anyone want to clarify these gripes with some science? I would like to make good decisions, but so far all I see on this topic is vapid and unsubstantiated rumor mill stuff.
