What is it, exactly, that makes people unwisely crave luxury goods? Now we know: it's chocolate truffles. Science has proven it!:

"Indulging in just one small chocolate truffle can induce cravings for more sugary and fatty foods—and even awaken a desire for high-end status products, according to a new study in the Journal of Consumer Research."

That's right! The study showed that people who ate a chocolate truffle subsequently reported they wanted lots of pizza and other crappy foods, too. Those who resisted the truffle were like, "Nah, I'm cool." Truffle eaters also desired "status products" including Apple computers more, so beware of any store handing out free truffles, okay!

But look how suggestible we all are; sheep, the lot of us:

Once people felt their goals were met, they tended to reverse their behaviors. For example, when people who resisted the truffle were told they did a good job, they indicated that they desired fatty foods more than healthy foods.

Reverse psychology, people. It works. [Science Daily]
