Unfortunately that means that I can't really eat any of the "kettle cooked" potato chips; they are invariably fried in the stuff. Actually that's how I figured out what was causing my internals to cramp up so badly; once I figured it was those potato chips that did it I started looking into what might be making that happen; turns out that a significant proportion of people have that reaction in greater or lesser degrees to that crap.

N.B. by significant I'm talking about somewhere between one in six and one in five. Just turns out that I'm on the outer edge of strength of it.
