In the 11th Century Ibn-Sina admistered coffee as a medicine. In fact drinking coffee has many positive effects. In our increasingly busy and demanding lives it reduces fatigue and enhances concentration to improve performance.

For those who drink coffee to stay alert, new research suggests that you'll stay more alert, particularly if you are fighting sleep deprivation, if you spread your coffee consumption over the course of the day. For instance, if you usually drink one large cup in the morning, try consuming one eighth of that serving every hour or so.

Studies show that the risk for Type 2 Diabetes is lower among regular coffee drinkers than among those who don't drink it. This study found that men who drank more than six cups of caffeinated coffee a day cut their risk of diabetes by more than half, while women reduced their risk by 30 percent.
Caffeine-free coffee doesn't seem to have the same effect. Diabetes Type 2 can lead to heart disease, stroke, blindness, limb loss and other disabilities.

Drinking coffee has also been linked to reducing the risk of developing Parkinson’s disease, gallstones and colon cancer, and is said to reduce the risk of liver damage in people at high risk for liver disease.
