When you smell cookies baking in an oven, sometimes you simply cannot resist letting loose a nonsensical explosion of language. “Staframonglaparthenar!” you might exclaim, not worrying a great deal about who might hear you. However, the question that hangs int he air from one of these episodes is why we tend to love the smell of baking cookies so much? Certainly, as human beings or maybe even as animals, we are evolutionarily pre-disposed to be attracted to the smell of food, but it seems like cookies are especially delicious and tantalizing when the smell hits our nostrils. The secret lies, not surprisingly, in the ingredients that cookies use. Back when our ancestors lived in caves, energy was at a premium. This means that food with high sugar content that could deliver a quick hit of energy was something that our bodies’ craved. This corresponds to the sugar in the cookies.
