A study of Massachusetts schoolchildren found that for each additional sweet drink per day, the odds of obesity increased 60 percent. Many schools stopped selling soda or artificial juice to students in light of those findings, but experts think that's not enough.

"Getting them out of the schools doesn't solve the problem completely because a lot of these drinks are consumed in the home," Bener said.

And obesity is far from the only health risk soda has been linked with.

A 2010 study in the journal, "Diabetes Care," found daily soda drinkers were 25 percent more likely to develop type 2 diabetes. Also phosphoric acid, a main ingredient in soda, has been linked to bone loss in those getting more of the chemical than calcium, according to WebMD. Too much caffeine has also been associated with bone loss, in addition to insomnia, high blood pressure and headaches.

And the diet stuff isn't much better. A 2011 study found daily diet soda drinkers were at a 61 percent higher risk for stroke and heart attack, Medscape reported.
