We know that sugar has an undesirable effect on our waistline, but now TIME Magazine reports that fructose may mess with they way our brains process rewards.

A new study shows a type of sugar found naturally in fruit may increase cravings for high-calorie foods.

The researchers gave the volunteers cherry-flavored drinks that were sweetened with fructose on one day and drinks sweetened with glucose on another day, and asked them to report their hunger levels.

Neuroimaging scans of the participants showed more activity in the orbitofrontal cortex and visual cortex of their brains, which are involved in reward processing, when they looked at images of food after they ingested fructose compared to glucose.

The researchers also showed the men and women images of high-calorie foods and asked if they would like to have food now, or if they would like a monetary bonus later on. When drinking fructose, the individuals were more likely to say they wanted the food reward right away rather than money later on.
