Trans fats are partially hydrogenated oils. So if they're not, am I mistaken to think that they have to be either fully unsaturated or fully hydrogenated? Anything in between has to be transfats? I'm sure I'm wrong thinking this way somehow.
Forgive me if i am repeating something, as i have not read this entire thread. But i have asked a chemist about trans fats, and he explained that a double bond between two carbons was a necessary condition for trans fat - hence full saturation would eliminate trans fats, because all the carbons would share single bonds. Also triple bonded carbons cannot have the trans configuration. But just because a fat molecule has a double carbon bond, that does not mean it is in the trans configuration.
The trans fat molecule is, as far as i understand, counted as an unsaturated (or possibly monounsaturated) fat molecule. It's not as if it's some different kind of fat.
I have read that there are naturally occurring trans fats in dairy, from the cow's hydrogenating of the unsaturated oils it's consuming. I have also read that oil extraction and deodorization processes create trans fats in oils. I don't know whether there are other natural processes that create trans fat. I don't know whether this configuration occurs naturally without any hydrogenating process.

. Like tara said, partially hydrogenated oils contain trans fats. The trans fatty acids are between unsaturated and saturated. Fully hydrogenated oil contains no trans fats.
