Coffee healthy drinking coffee can increase memory

People who drink too much alcohol, drinking coffee or tea, can help reduce the damage caused by alcohol to the liver, as well as people with high levels of iron in their blood, according to a US study.

In addition, Austrian research shows that drinking coffee does increase activity in the area of the brain responsible for short-term memory and has a "refreshing" effect.

The study, conducted by the National Research Center for Diabetes, Digestive tract and Kidney Diseases and Social and Scientific Systems, on the 4th, analyzed nearly 10,000 subjects and found that people who drank too much, if they drank more than two cups of coffee or one cup of tea a day, were half as likely to develop chronic liver disease as those who drank less than that amount of coffee and tea a day. However, coffee and tea have no such effect on liver disease caused by other causes.

"although it is too early to encourage patients to increase their consumption of coffee and tea, our findings still have the potential to provide a way to reduce morbidity in high-risk groups of chronic liver disease," said Ruhr, who led the study. in addition, we hope that this finding will provide a guide for liver disease research. "

Ruhr's study, published in the Journal of Gastroenterology of the American Society of Gastroenterology, involved 9849 people who took part in a government health survey and asked them how much coffee and tea they drank during a 19-year follow-up.

In addition, an Austrian study shows that coffee can really be "refreshing" because coffee, tea, soft drinks or chocolate can stimulate the prefrontal lobe, the area of the brain responsible for short-term memory and attention. The researchers used MRI to observe the brain activity of 15 subjects after drinking coffee. After drinking two cups of coffee, there was an increase in activity in the prefrontal lobe and anterior cingulate cortex, which is responsible for short-term memory and the latter is associated with attention control.

"We have seen caffeine increase neural activity in specific areas of the brain and have changes in behavior," said Dr. Kopstadt, who led the study at the University of Innsbruck School of Medicine. "

The subjects did not drink any caffeinated drinks for 12 hours, did not touch nicotine for another 4 hours, and then drank 100 milligrams of coffee before the test. as a result, their memory letters performed better than those who took a placebo. the reaction time of short-term memory also improved. Next, the researchers report, they will test whether caffeine is also good for long-term memory.

According to the North American Radiology Society, the global daily caffeine intake is 76 milligrams, equivalent to one and a half cups of coffee. In the United States, the average daily consumption is 238 milligrams, about four and a half cups.
