Anyone who's cleaned out a minivan can attest that McDonald's food just...doesn't...age. A fresh-looking burger lies stiffly next to a completely rotted apple core. The fries scattered in the backseat are hard and cold, to be sure, but there's not a spot of mold on them. And it's been weeks since the kids had those Happy Meals! What gives?
There's long been speculation that this food fountain of youth is due to a massive amount of preservatives. But McDonald's maintains that their burgers, at least, are completely preservative-free.
The answer may not be quite as sinister as suspected. Although McDonald's hasn't actually fessed up to whether preservatives lurk in anything other than its burgers, there are scientific explanations for what Salon calls this "shelf life of the undead," and while they're not exactly scary, they're not exactly healthy, either. Rather than huge levels of chemicals, we're talking hefty servings of fat and salt.
