Watching how processed foods are produced via a show like How It's Made is enough to keep me from eating most things that come in bags, boxes, or plastic containers. I sometimes prefer to be a part of the equation Ignorance = Blissful eating of cookies.
Oh, and stinky cheese will keep you from eating most things. We've decided the stink may be unnintentional and actual spoilage, so we've called the place where we bought it to lodge a small complaint/question. We shall see.
You can smell it through the ziplock baggie, too.
