Research showed that obsessing over a sweet treat is not good for the brain since it makes it difficult to concentrate on other tasks.

Scientists said that these cravings have consequences ranging from simple memory lapses to car crashes. They conducted a study to see whether the intensity of these desires affects our ability to concentrate on other things.

The researchers from Flinders University in Melboune Australia believe that when we crave a food we draw a mental picture of it. This picture ties up brain regions needed for other tasks.

“Although cognitive effects of individual food cravings are likely to be small, in practice even small reductions in cognitive resources have the potential to compromise optimal performance in everyday situations, thereby reducing work efficiency or increasing the likelihood of accidents,” the researchers said.
