Is Junk Food as Addictive as Cocaine?

Cupcakes may be addictive, just like cocaine.

A growing body of medical research at leading universities and government laboratories suggests that processed foods and sugary drinks made by the likes of PepsiCo Inc. and Kraft Foods Inc. aren’t simply unhealthy. They can hijack the brain in ways that resemble addictions to cocaine, nicotine, and other drugs.

“The data is so overwhelming the field has to accept it,” said Nora Volkow, director of the National Institute on Drug Abuse. “We are finding tremendous overlap between drugs in the brain and food in the brain.”

The idea that food may be addictive was barely on scientists’ radar a decade ago. Now the field is heating up. Lab studies have found sugary drinks and fatty foods can produce addictive behavior in animals. Brain scans of obese people and compulsive eaters, meanwhile, reveal disturbances in brain reward circuits similar to those experienced by drug abusers.
