Coffee consumption origins

Coffee was originally consumed as a food in ancient Abyssinia and was presumably first cultivated by the Arabians in about 575 AD (1). By the sixteenth century it had become a popular drink in Egypt, Syria, and Turkey. The name coffee is derived from the Turkish pronunciation, kahveh, of the Arabian word gahweh signifying an infusion of the bean. Coffee was introduced as a beverage in Europe early in the seventeenth century and its use spread quickly. In 1725, the first coffee plant in the western hemisphere was planted on Martinique, West Indies. Its cultivation expanded rapidly and its consumption soon gained wide acceptance. 

The proportion of coffee consumption has to be more than 50%. Harvard scientists failed to confirm its original findings during a follow-up study... 

A relation between coffee consumption and pancreatic cancer was originally reported in a case-control study (SEDA-7, 8), with an unexpected increase in pancreatic cancer in coffee drinkers (relative risk in men 2.6). The same group studied differences in mortality from pancreatic cancer in different countries in relation to differences in coffee consumption and found a significant relation between increases in coffee consumption and increases in mortality from pancreatic cancer. However, the data on which the findings were based were crude.
