Sounds like your describing the hydrogenation process. Question is: is it
only hydrogenation that produces trans-fatty acids? I, too, was under the
impression that high heat for vulnerable oils "denatures" the oil (i.e.,
produces trans fats).

cooking. I'm no chemist, but that is what I've been told by
colleagues, one of whom specializes in "food chemistry.">>
