Report Finds Junk Food and Cocaine Have Similar Brain Effects
A new study finds fatty foods and junk foods cause rats to overeat, triggering the same mechanism in the brain as cocaine.
Doing drugs such as cocaine and eating too much junk food both gradually overload the so-called pleasure centers in the brain, according to Paul J. Kenny, Ph.D., an associate professor of molecular therapeutics at the Scripps Research Institute, in Jupiter, Florida. Eventually the pleasure centers "crash," and achieving the same pleasure--or even just feeling normal--requires increasing amounts of the drug or food, says Kenny, the lead author of the study.
