Question: what is the difference between caffeine and soda?
Answer: Both contain caffeine, yet the amount differs considerably. According to MedlinePlus, while an 8-ounce cup of coffee contains 95 to 200 milligrams of caffeine, a 12-ounce can of Coca-Cola contains 35 to 45 milligrams of caffeine. In other words, coffee contains three to four times more caffeine than Coca-Cola.
