Coffee is a brewed drink made from roasted coffee beans, which are seeds from the Coffeaplant native to Africa. The plant has been exported around the world and is now cultivated in over 70 countries, primarily in equatorial regions. Coffee contains caffeine and has a stimulating effect on humans. It is one of the most popular drinks in the world and can be prepared and served in various ways, usually hot but sometimes iced. Moderate coffee consumption is generally considered benign or mildly beneficial for healthy adults.
