According to an October 15 news release from Connecticut College, neuroscience students and a professor have discovered that, based on experiments on laboratory rats, Oreo cookies are just as addictive as cocaine or morphine. Paralleling the human tendency, the rats went for the creamy middle first.
The research was led by Professor Joseph Schroeder and his students, who designed the study to discover the extent of the potential addictiveness of high fat and high sugar foods on rats. The researchers found that rats developed an affinity for the pleasurable effects of eating Oreos in a specific environment, just as they did for cocaine and morphine. Additionally, the researchers discovered that when the rats ate the cookies, more neurons were activated in the brain’s pleasure center than exposure to typical drugs of abuse.
