Coffee is slightly acidic (pH 5.0–5.1) and can have a stimulating effect on humans because of its caffeine content. It is one of the most consumed drinks in the world. It can be prepared and presented in a variety of ways. Coffee is a brewed beverage prepared from the roasted seeds of several species of an evergreen shrubof the genus Coffea. The two most common sources of coffee beans are the highly regarded Coffee arabica, and the "robusta" form of the hardier Coffea canephora. The latter is resistant to the coffee leaf rust (Hemileia vastatrix), but has a more bitter taste.Coffee goes at least as far back as the thirteenth century with a number of myths surrounding its first use. The original native population of coffee could have come from Ethiopia, Sudan or Kenya, and it was cultivated by Arabs from the 14th century. The earliest credible evidence of either coffee drinking or knowledge of the coffee tree appears in the middle of the fifteenth century, in the Sufi monasteries of Yemen.By the 16th century, it had reached the rest of the Middle East, Persia, Turkey and northern Africa. Coffee is said to have come from Brazil in the hands of Francisco de Mello Palheta who was sent by the emperor to French Guiana for the purpose of obtaining coffee seedlings. But the French were not willing to share and Palheta was unsuccessful. In only 100 years, coffee had established itself as a commodity crop throughout the world. Missionaries and travellers, traders and colonists continued to carry coffee seeds to new lands and coffee trees were planted worldwide.
One of the ironies about coffee is that it makes people think. It sort of creates egalitarian places — coffeehouses where people can come together — and so the French Revolution and the American Revolution were planned in coffeehouses. On the other hand, that same coffee that was fueling the French Revolution was also being produced by African slaves who had been taken to Santo Domingo, which we now know as Haiti.Coffee then spread to Balkans, Italy and to the rest of Europe, to Indonesia and then to the Americas.

The risk was more than 50 percent higher in adults under 55 years old.Younger men who drank about 28 cups per week were 56 percent more likely to die prematurely from any cause than those who didn't drink any coffee. Younger women who drank that much java doubled their mortality risk compared to those who didn't. Caffeine content can range from as much as 160 milligrams in some energy drinks to as little as 4 milligrams in a 1-ounce serving of chocolate-flavored syrup.
