Students and a professor of neuroscience have found “America’s favorite cookie” is just as addictive as cocaine – at least for lab rats. In a study designed to shed light on the potential addictiveness of high-fat/ high-sugar foods, they found rats formed an equally strong association between the pleasurable effects of eating Oreos and a specific environment as they did between cocaine or morphine and a specific environment. They also found that eating cookies activated more neurons in the brain’s “pleasure center” than exposure to drugs of abuse.
