Oreos used to be high on my yummy list, but not anymore. Like taryl, just thinking about what is in them, majorly grosses me out now. Partially hydrogenated fats are basically like candle wax, and when I think about it that way...not so yummy anymore!
And besides...I can find plenty of delicious, calorie-rich foods that aren't made from junk, so I'm just a little pickier when I indulge. :-)
