It’s no secret that soda is bad for you, but 48 percent of Americans drink it every day, according to Gallup. The average daily amount is 2.6 glasses, with 28 percent drinking one glass a day, on average, and 20 percent drinking two or more glasses. The high fructose corn syrup found in soda is among the worst thing about it. Many other drinks, however, don't fare much better - sometimes for different reasons.
