Below is the latest coffee research from Barcelona University...How come I never get called for this kind of research!? I'd love to make money taking COFFEE Surveys! Anyway, Dunkin' Donuts coffee is the best Christmas present for me!
A strong cup of coffee has a greater effect on men than women, research shows. In a study on 668 healthy volunteers, an espresso pepped up men after just 10 minutes. Women also became more alert after the beverage, but less so.
The University of Barcelona researchers say some of this effect might be psychological because decaffeinated coffee also worked to some extent. Progress in Neuro-Psychopharmacology & Biological Psychiatry reports the work.
The volunteers were asked to drink either a classic espresso containing 100mg of caffeine or a decaffeinated espresso containing 5mg of caffeine.
Then the researchers looked for changes in alertness over the following minutes and hours. Both men and women saw an improvement in their activity levels after drinking the classic espresso and these effects began after as little as 10 minutes.
According to the investigators, 45 minutes is the time needed for maximum caffeine concentration to be reached in the blood, but levels reach half this concentration after just a few minutes. And the effect appeared to be greater in the men.
Interestingly enough, DECAF coffee had a similar, but weaker effect and tended to be more potent in the women rather than in the men.
