Coffee is a brewed beverage with a very strong flavor and people love it for its slightly bitter and energizing effect. Coffee is also one of the most-consumed and popular drinks in the world. It was calculated that 54% of all Americans who are over 18 years old drink coffee on a regular basis.
Many scientists have examined whether coffee and its strongest active ingredient caffeine have positive or negative effects on our physical and mental health. Although the conclusions are disputable, according to recent experiments conducted in the US a cup or two of coffee per day may greatly boost our mental capacity. It was also proven that coffee enhances our ability to retain information for longer periods of time.
The experiments were led by Michael Yassa who is a neuroscientist based at the Johns Hopkins University. His conclusion was that caffeine unleashes a powerful stress hormone in our brains called norepinephrine. This hormone helps the brain lay down memories faster and more efficiently thus making us remember stuff more permanently.
Although the results of Yassa’s small-scale experiment are disputable, it’s good to know there is another positive attribute to the moderate daily consumption of coffee.
