 Can someone (like Sarah) confirm this.  I understood that not all oils are
 born equal.  Something to do with tryglycerides or something?  I had a long
 conversation with an English vet who worked (may still work) in the UAE
 (this was a while back) and he gave me chapter & verse about these
 tryglycerides things.  I nodded wisely at the appropriate moments, not
 knowing what the hell he was talking about. >>

I'm sure Sarah could explain this better, but oils (and in fact, all fats) 
are made up of different fatty chains linked in little "troikas" called 
triglycerides.  Different chains have different properties--more or less 
"saturation" (how many hydrogens are hooked on--used to be called 
"hydrogenation"), more or less "trans" linkages, etc.  All those properties 
affect things ranging from digestibility to stability in storage, to 
stability in the body in the face of free radicals, etc., etc.  So no, not 
all oils are created equal.
