The history of coffee started in Ethiopia. Coffee came to Europe from Venice that had strong trade relations with the Arab world in the late 16th century.
The coffee is for hundreds of years an integral part of the Greek culture, indispensable in the morning to start the day well and important for good digestion after lunch.
The most known effect of coffee is related to the nervous system as it improves mental abilities and causes wakefulness. The main reason is that coffee contains caffeine, an alkaloid that acts as a stimulant.
