Fake Popcorn Butter

Dripping real melted butter all over your massive tub of salty popcorn would be enough of a cholesterol bomb on its own, but that thin robo-butter that you slather all over your corn is downright scary. You know what that stuff is? It's called diacetyl, and adds a buttery taste to things without any actual butter. Sounds great, right? Wrong. A recent study by the University of Minnesota has linked diacetyl to Alzhheimer's disease. Is that why today's movies seem so forgettable?
