Oily Stool Debate

Nabisco Double Stuff Oreo's From the Stateside Candy Co, originally uploaded by chantelle.

I really need your help. I have an Oreo fetish which is no thing, I'm sure many biscuit munchers do. However I was told that in America Oreo's used to carry a warning that consumption could/would cause oily stools. Now without going deep into this, I've not experienced problems and I got issues. When in Miami I checked the packet and no mention, so what the deal sons and daughters? Are we destroying our rectums with these fine specimens or is all well in love and cookies?
