Study Links Impulsivity to Food Addiction
For some people, struggles with food feel addictive. Research shows a common link between drug and food addiction. For certain people, this type of addiction may be linked to impulsivity, which researchers suggest might also be biologically based.
BUSM researchers measured the inability to withhold an impulsive response in experimental participants that were exposed to a diet high in sugar daily for one hour. Participants shown to be more impulsive rapidly developed binge eating, showing heightened cravings and the loss of control over the junk diet (measured as inability to properly evaluate the negative consequences associated with ingestion of the sugary diet). Conversely, participants shown to be less impulsive demonstrated the ability to appropriately control impulsive behavior and did not show abnormal eating behavior when exposed to the sugary diet.
Study authors also found that the “impulsive models showed increased expression of a transcription factor called Delta-FosB in the nucleus accumbens, an area of the brain involved in reward evaluation and impulsive behavior, indicating a potential biological component to this behavior.”
“Our results add further evidence to the idea that there are similar mechanisms involved in both drug and food addiction behavior,” said Clara Velazquez-Sanchez, PhD, postdoctoral fellow in the Laboratory of Addictive Disorder and first author of the study.
Their research also seems to suggest that it’s not diet alone that contributes to impulsive, addictive, binge eating or compulsive behavior. There’s more to it than just sugar. It’s also the brain behind the sugar.
