Researchers at the University of Barcelona in Spain found that taking coffee and sugar at the same time boosted the brain's performance more than taking them on their own.

Researchers believe that both caffeine and sugar enhance the effect of each other on cognitive skills such as learning, concentrating, and retrieving.

Previous studies have also established that coffee improves short-term memory and speeds up reaction time by acting on the brain's prefrontal cortex.

For the purpose of the study, researchers carried out a study on 40 participants, who were tested on three conditions: coffee with sugar, coffee without sugar, sugar on its own or just plain water.

"The two substances improve cognitive performance by increasing the efficiency of the two areas of the brain responsible for sustained attention and working memory," the Daily Mail quoted researcher Dr Josep Serra Grabulosa as saying.

But it's likely that coffee lovers who do not take sugar will get the same benefits from enjoying a sugary snack with their drink.

"The brain is more efficient under the combined effect of the two substances, since it needs fewer resources to produce the same level of performance than when volunteers took only caffeine, glucose or water," Serra Grabulosa added.

It can be learned that glucose, a type of sugar, is the main fuel which brain cells need in order to function properly.

The results have been published in the journal Human Psychopharmacology: Clinical and Experimental.
