How complicated things must get then, when that wisdom is confounded by McDonald's Happy Meal. Author Nonna Joann Bruso has been keeping an online journal about the half-life of the Happy Meal. So far, a year has gone by, and the meal has shown no signs of rot, moulding, or decay.
My Conclusion: Food that doesn't break down is not actually food. The infamous Happy Meal may be one of North America's most gleefully recognised packages, but if it defies natural order, it is a paragon of sickness, uselessness, and a plague more than a food. The FDA really ought to have pseudo-foods like this incinerated. Permanently. McDonald's may have the golden arches, but it is inescapably obvious that "all that glitters is not [actually] gold."
