Drinking coffee is healthy. Drinking coffee with sugar is good for the brain.

Because they like the bitter taste of coffee, many people drink coffee without sugar and think that a touch of bitterness is its original taste. Sweetened coffee covers the aroma of coffee. Without the original charm of coffee, it cannot be called coffee. However, the study found that caffeine and sugar can promote each other, improving brain functions such as attention span and working 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 eating caffeine and sugar at the same time can improve the efficiency of the brain than eating caffeine or sugar alone. Caffeine and sugar can promote each other and improve 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 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 the standard test method to test the participants' attention span and working memory, and their brains were scanned by magnetic resonance imaging (MRI). The results showed that after drinking sweetened coffee, the participants had bilateral frontoparietal lobes.

There is a significant decrease in activity in the cortex and left prefrontal cortex, two brain regions responsible for attention and memory, and reduced activity in these areas, which means the brain works more efficiently.
