A small new study suggests the brain responds to Oreo cookies quite like it responds to actual drugs – at least if you’re a rat. The “pleasure center” of the brain, the nucleus accumbens, apparently gets just as activated in response to Oreos as it does to cocaine and morphine, which could actually have some major public health implications. While the study was done in rats, the authors say it’s likely relevant to humans as well, and could explain why people have such a hard time resisting eating an entire sleeve of the cookies. The study, which will be presented at the Society for Neuroscience’s annual conference next month, also made another discovery: Rats, like humans, like to eat Oreo’s creamy center first. To test how the animals responded to Oreos vs. drugs, the team trained mice to navigate a maze. On one side, Oreo cookies were provided, and on the other side plain rice cakes were offered. As you’d guess, the rats were significantly more likely to spend time on the Oreo side of the maze. The team also compared these results to rats who were trained with morphine or cocaine rather than Oreos. They found that regardless of what “substance” the rats were offered (Oreos, cocaine, or morphine) they spent about the same amount of time on the “drug” side of the maze.
