The sugar habit
A new study from researchers at Duke University finds that a sugar habit leaves a lasting imprint on certain brain circuits, making it incredibly difficult to stop eating sweet food. These marks, in turn, prime us to give into our cravings.
With this new knowledge of how sugar and other vices affect the brain, researchers may one day be able to target these circuits to help people kick bad habits and form healthy ones.
Scientists have known for some time that sugar can be addictive, hijacking the brain’s reward networkings and creating a cycle of vicious cravings. But the new study, which was published in the journal Neuron on Thursday, is helping neuroscientists to better understand why it’s so hard to beat those cravings.
