Drinking coffee with sugar is good for memory.

According to foreign media reports, a new Spanish study published in the journal Human psychopharmacology: clinical and Experimental Medicine has found that drinking coffee with sugar is good for the brain and can improve memory and attention span.

Scientists at the University of Barcelona in Spain have found that simultaneous intake of caffeine and sugar improves brain productivity than caffeine alone or sugar alone. Caffeine and sugar can promote each other, improving brain functions such as attention span and working memory.

Forty participants were given MRI scans of their brains after drinking sweetened coffee, unsweetened coffee, sugar or plain boiled water. A comparative study found that drinking a cup of sweetened coffee in the morning is the best way to deal with a busy day.

On the one hand, caffeine has an exciting effect, stimulating the brain to work and combat drowsiness and fatigue, the researchers said. A number of early studies have found that drinking three cups of coffee a day can significantly reduce Alzheimer's disease, and its key role is that caffeine triggers a series of chain reactions in the brain to prevent brain tissue damage. On the other hand, glucose is one of the main "fuels" necessary for brain cells to function properly.

Caffeine and sugar can complement each other and improve brain cognitive function more effectively, a new study has found. The researchers used standard tests to test participants' attention span and working memory, as well as magnetic resonance imaging scans of their brains, and found that after drinking sweetened coffee, there was a significant reduction in activity in the bilateral frontal parietal cortex and left prefrontal cortex, which are responsible for attention and memory, and reduced activity in these areas, which means the brain works more efficiently.
