Oreos are my weakness. I never buy them because if I do I will eat them to quickly.
Ditto. I typically will eat a third to half a package at once, the old fashioned way: dip them in milk, preferably whole milk (if you're eating oreos, skim vs. whole milk is like whether to wear cotton or leather in a grenade fight. Sure, it'll probably make a difference, but not getting into a grenade fight in the first place is probably the smarter decision).
Actually, original Oreos were probably designed to maximize the specific health consequence density, without using toxic chemicals like mercury, etc. In addition to being refined sugar and fat, they also had an obscene amount of trans fat in them. They wouldn't show it on the labels, but I was lucky enough to come across a package that gave detailed fat listings. For two cookies, it was something like 7.5g total, 2.5g saturated, 1.5g poly, 1g mono. Do the math, and 2.5 grams is missing. My bet is that's trans fat. Or, about 1g per cookie.
1g doesn't sound like a lot, but I read a study somewhere that 2% of calories on a daily basis from trans-fat can increase diabetes risk 39%. 2% of 2500 calories works out to 50 calories, or 5.5 grams roughly, so each gram per day is presumably increasing risk of diabetes by about 7%-8%. Doesn't sound too bad, except that that's just the trans-fat. Throw in the refined high GI carbs, and eating one Oreo a day, in place of a similar number of calories from, well, probably just about anything else, will significantly increase your risk of diabetes. Go through a package of Oreos a week, and you might actually be able to chart your decline to diabetes in a few years.
Anyway, I'm still a sucker for Oreos, but I've since switched to the reduced fat ones ("0g" trans-fat, but that just means 0.499g or less per serving probably). Ironically, I like them better than regular Oreos: they're denser, if that makes sense. More like cookies, less like wafers. They taste a little difference, but I like it. So I can have my cookie and eat it too.
