Coffee and caffeine

Caffeine effects

Some people believe that a large cup of coffee contains less caffeine than an espresso coffee when the truth is the opposite. there is less caffeine in a very strong espresso coffee since the use of lesser amount of water extracts less substances from the blend. For those who wish to enjoy a large cup of coffee, without increasing the amount of caffeine, the solution we recommend is to add hot water to a normal coffee. it is also important to remember that the various coffee blends may contain different amounts of caffeine: coffees belonging to the arabica species generally have a lower content of caffeine than the commonly defined robusta species.

In any case, however, the caffeine consumed by drinking coffee is sufficient enough to give a stimulating effect to the central nervous system.

The best solution in order to eliminate the undesired effects of caffeine is to enjoy a pleasant decaffeinated coffee.

Caffeine has pharmacological effects on the respiratory, renal, cardiovascular and nervous systems.

A list of the effects of caffeine are given in the following table (taken from Daly J.W, Mechanism of action of Caffeine, Caffeine Coffee and Health, Raven Press Ltd., New York, 1993)):

The most known effects are obviously those of the stimulation on the nervous system that may cause both positive effects (improvement of cognitive and working skills) and a negative one (difficulty in falling asleep).
