The Cookie That’s As Addictive As…Cocaine?

    A stack of OreosNew research suggests that a particular treat can elicit the same reaction and activate the brain in a similar manner as cocaine and morphine.

    Joseph Schroeder, an assistant professor of psychology and director of the Behavioral Neuroscience Center at Connecticut College, presented the study at the Society for Neuroscience conference in San Diego, Calif. The cookie that the study focused on?

    Oreos.

    Oreos weren’t specifically singled out for their ability to trigger a snack attack, they were just a handy device to get enough fat and sugar in the rat’s habitat, Schroeder said.

    For their study, the students gave Oreos to hungry rats on one side of a maze, and on the other side of the maze they gave them a “control” food, in this case, rice cakes (Prof. Schroeder comments that like humans, rats do not seem to relish rice cakes very much).

    Then they gave the rats the option to go to either side of the maze (without the food present), and measured how long they spent on the side where they were typically fed with Oreos compared with the side they were fed with rice cakes.

    The researchers then repeated the experiment with another group of rats. This time, instead of feeding them Oreos and rice cakes, they injected them with addictive drugs – such as cocaine and morphine – when they were on one side of the maze, or saline, when they were on the other side. (Prof. Schroeder is licensed to carry out this kind of experiment).
