Cola is a sweet carbonated drink, usually with caramel coloring and containing caffeine.The flavor of the soft drink sometimes comes from a mixture of vanilla, cinnamon, and citrus flavorings. The name comes from the kola nuts that were originally used as the source of caffeine.

Cola drinks may be sweetened with sugar, corn syrup or an artificial sweetener depending on product and market. Caffeine-free cola drinks are also available.

Recently a study shows that women who want to keep their bones strong may want to keep their cola consumption to a minimum.
