Scientists at Connecticut College performed a new study to see how addictive Oreo cookies really are. Using lab rats, the researchers performed two tests with Oreos and rice cakes in one maze and cocaine and saline in another. Needless to say, the rats took to the Oreos and cocaine far more than the rice cakes and saline. Scientists say this study shows that foods high in fat and sugar are just as addictive as illegal narcotics.
