Sugar addiction: no longer a metaphor

Loading Likes...

Most people hear the phrase “sugar addiction” as a metaphor. A new study from Denmark indicates that sugar addiction is literal. Dr. Michael Winterdahl, one of the scientists who led the study, wanted to refute the idea that sugar was physically addictive. The evidence changed his mind:

“After just 12 days of sugar intake, we could see major changes in the brain’s dopamine and opioid systems. In fact, the opioid system, which is that part of the brain’s chemistry that is associated with well-being and pleasure, was already activated after the very first intake,” says Winterdahl.

The study from Aarhus University is explained in layman’s terms in this article from MedicalXpress.com. The technical English-language summary on the Aarhus University site is here.
