What is the most consumed beverage after water? With 30 billion cups drunk in France each year is the coffee. Yet, everyone does not like coffee and many French prefer him tea. There are clearlyfans of coffee and tea enthusiasts.This preference for either of these drinks did an explanation? Why do we prefer tea or coffee ?
The common point between coffee and tea is caffeine, but caffeine is also a preference that will ...
The coffee and tea both contain the caffeine. But tea contains two less caffeine than some coffee.

In other words, among those who transformed the intensely caffeine in paraxantine, the effect anxiolytic for anxiety paraxantine predominates over that of caffeine.

In contrast, people who are transforming the caffeine in paraxantine feel especially effects anxiety of caffeine. Coffee can generate a crisis and acute anxiety. So for them, drinking coffee is not beneficial. Result, they do not like coffee.
They refer to the tea, because with a little caffeine, the drink gives them stimulation sought. However, the tea does not contain enough caffeine to be anxiogenic. Moreover, the théamine (a derivative of the acid glutamine tea) also has stimulant properties that help to moderate the effect of the anxiogenic caffeine.
