I've not heard of camelina oil.

I don't cook much and didn't really have any interest in food oils until three or four years ago when my cardiologist wanted to do some unpleasant sounding invasive procedures. Instead, I got serious about my diet and supplements, which lead me to cut out most vegetable oils from my diet, among other things. That's when I found that canola and other less-than-healthy oils are damn near everywhere in processed foods. Canola oil is cheap, so it's one of the most common. In my favorite local health food store, several of the organic mayo brands have canola oil as the number 1 or number 2 ingredient.

My cardio problems went away -- big change, actually -- and cutting the vegetable oils was, I believe, the biggest factor in that.
