Drinking coffee with sugar is good for the brain

The researchers gave 40 participants an MRI scan 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.

The researchers point out that, on the one hand, caffeine has an exciting effect, stimulating the brain to work and combat drowsiness and fatigue. Several early studies have found that drinking three cups of coffee a day can significantly reduce Alzheimer's disease, the key role of which 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 decrease 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.
