Coffee

Coffee as a drink, usually served hot, is prepared from the roasted seeds (beans) of the coffee plant. Due to its popularity, coffee is, in monetary terms, the second largest traded commodity in the world (after oil). It is one of mankind's chief sources of the stimulant caffeine. Because of this, coffee's nutritional benefits are disputed, sometimes labeled a cure-all, other times labeled a health hazard (see caffeinism).
