According to the Food and Drug Administration (FDA), nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. It was the equivalent of about one cup of strong coffee a day.

Writing in the publication of "Nature Neuroscience," researchers from Johns Hopkins University say they have discovered that caffeine has a positive effect on long-term memory in humans.
"We previously knew that caffeine has effects of cognitive enhancement, but the special effects in strengthening memory and make it last has not been previously studied in detail in humans," said the paper's senior author, Michael Yassa, a former researcher from Johns Hopkins who now works in University of California, Irvine.
"We were report for the first time specific effect of caffeine on reducing forgotten for 24 hours."
The researchers found that respondents who were given caffeine tablets can accurately identify the pictures that given earlier, compared with the no. They can recognize the difference between the two similar images, but not identical, or so-called pattern separation, and according to the scientists showed levels higher memory storage.
"The next step is to determine the mechanisms of the brain in these improvements," said Yassa.
"We can use brain imaging techniques to answer these questions. We also know that caffeine is associated with long-term health and may have a protective effect on cognitive decline such as Alzheimer's disease." *** [EKA | FROM VARIOUS SOURCES | VOA NEWS | DNA]
