Coca-Cola
Coca-Cola, or Coke, is a carbonated soft drink manufactured by The Coca-Cola Company. Originally intended as a patent medicine, it was invented in the late 19th century by John Stith Pemberton and was bought out by businessman Asa Griggs Candler, 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).
Diet drink
Diet (alternatively marketed as sugar-free, zero-calorie or low-calorie) drinks are sugar-free, artificially sweetened versions of fizzy beverages with virtually no calories.

However, studies show that the marketed effectiveness of diet soft drinks is questionable.
