I heard that an experiment was recently done, in which they took a burger from MacDonald's, and a homemade one, and some fries from MD, as well as homemade ones, and let them rot for 10 weeks. The result: all the food shrank, much like on the video, except for the MacDonald's fries; they did not change at all.
The conclusion: they're dangerously high in preservatives.
