Coca-Cola, or Coke, is a carbonated soft drink manufactured by the Coca-Cola Company. Originally marketed as a temperance drink and intended as a patient medicine, it was invented in the late 19th century and was bought out by businessman, whose marketing tactics led Coca-Cola to its dominance of the world soft-drink market throughout the 20th century. The drink's name refers to two of its original ingredients: coca leaves, and kola nuts (a source of caffeine). The current formula of Coca-Cola remains a trade secret; however, a variety of reported recipes and experimental recreations have been published. The drink has inspired imitators and created a whole classification of soft drink.
Benefit of drinking Coke is that it contains caffeine, a natural stimulant found in the kola nut, coffee beans and tea leaves. Caffeine makes you feel more alert when you're tired and might increase your performance when embarking on certain tasks.
