You could dunk (泡一泡), twist, lick or bite it. Though consumers have no agree mention the best way to enjoy Oreos, a kind of sandwich cookies, the ways of eating the cookies are really so attractive.

Food scientists and specialists in the field of sensory studies, however, can offer some research-backed methods for gathering pleasure from an Oreo.

The 40 billion Oreos produced each year are commonly sweet, but they also pack a certain amount of fat. And as food scientists know, sugar and fat make a winning mixture if you reaiming to inspire your brain’s reward system.

But Oreos don’t attract you with taste alone; scents have a huge impact on the eating experience. When you bite into an Oreo, chemicals in the cookie release odor ants into the air inside your mouth. These scents flow to your nasal cavity (鼻腔), where they interact with smell receptors (感受器) and enter your brain’s decoding (解码) process. Your brain is likely to find those smells delightful, says Charles Spence, a professor of experimental psychology at the UK’s University of Oxford. Spence says chocolate and vanilla are two of the world’s most liked smells.

Childhood memories are probably another key driver of our Oreo enjoyment. Foods that stimulate memories have been linked to positive emotions, suggests a paper. So, whether you’re a dunker, a twister, a licker or a fast snacker, you might boost your cookie experience by stimulating simpler, more carefree moments, and eating like you’re a kid again. Oreos might remind you of that period of your life when you were looked after. Biting into an Oreois like your brain saying: Somebody loves you.
