„Of all the physiological effects of coffee, the best known is that it is a stimulant to the nervous system. One or two cups of coffee can make one feel more awake, alert and able to concentrate. Caffeine has been shown to counteract fatigue and restore flagging performance.

"The latest research demonstrates, however, that when people don't get their usual dose they can suffer a range of withdrawal symptoms, including headache, fatigue, difficulty concentrating. They may even feel like they have the flu with nausea and muscle pain."“

„If your morning routine includes a cup or two of coffee, you may know a few things about it. It's a stimulant drink, it comes from beans that are roasted and ground and, for many of us, it's a staple of life. But do you know where coffee grows and how it gets to America?
