Spanish study found that drinking coffee with sugar improves memory and attention

According to the latest reports in foreign media, a new Spanish study published in the journal Human Psychopharmacology: Clinical and Experimental has found that drinking coffee and sugar is good for the brain and can improve memory and attention span (attention span).

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

The researchers gave 40 participants an MRI scan of their brains after drinking sweetened coffee, unsweetened coffee, sugar or plain water. A cup of sweetened coffee in the morning was the best way to cope with a busy day, the study found.

On the one hand, caffeine has a stimulating effect, stimulating the brain to work and fighting sleepiness and fatigue, said Dr. Sepp Serra Grabrosa, who led the new study. Earlier studies have found that drinking three cups of coffee a day significantly reduces Alzheimer's disease, and the key role is that caffeine triggers a chain reaction in the brain that prevents damage to brain tissue. Glucose, on the other hand, is one of the main "fuels" necessary for brain cells to function properly.

New research has found that caffeine and sugar complement each other and promote each other more effectively to improve brain cognitive function. The researchers used standard tests to test participants 'attention span and working memory, and MRI scans of their brains were performed. The results showed that after drinking sweetened coffee, the participants had significantly reduced activity in the bilateral frontal parietal cortex and left prefrontal cortex, two brain regions responsible for attention and memory. Reduced activity in these areas signals that the brain is working more efficiently.
