A soft drink (see ยง Terminology for other names) is a drink that usually contains carbonated water (although some lemonades are not carbonated), a sweetener, and a natural or artificial flavoring. The sweetener may be a sugar, high-fructose corn syrup, fruit juice, a sugar substitute (in the case of diet drinks), or some combination of these. Soft drinks may also contain caffeine, colorings, preservatives, and/or other ingredients.
