A new study at Connecticut College finds Oreos are just as additive as cocaine and morphine, according to the professor who supervised the study.
Connecticut College's Joseph Schroeder said, "That may be one reason people have trouble staying away from them and it may be contributing to the obesity epidemic."
He said he figured since most people like the chocolate and cream cookie, rats might as well.
So the researchers crumbled up the cookies for the lab animals and were surprised at what they saw.
The rats liked the chamber where they were given cocaine and morphine just as much as the chamber where they got Oreos.
They ate the cream first.
The researchers reported the Oreos stimulated more neurons in the pleasure centers of the rats' brains.
"We looked at the pleasure center of the brain which is stimulated any time you engage in a pleasurable activity, including eating," Schroeder said. "Drugs of abuse hijack that system and lead to addiction."
A senior student in the study, Lauren Cameron, said she spent the summer feeding and analyzing the rats' brains.
"It really just speaks to the effects that high fat and high sugar foods and foods in general, can have on your body," Cameron said. "The way they react in your brain, that was really surprising for me."
Schroeder said he hasn't touched an Oreo since doing the experiment.
