Research is shedding some new light on an old problem. We've all heard that kids today are drinking too much soda, but girls in particular are seeing some health consequences we didn't expect.

They're hard to find but there are some teens out there who aren't drinking soda. But not all kids are like Erin Corkell and more and more, they're turning to sodas as their drink of choice. "A lot of people I know drink soda because it's really convenient, mean, you go to every fast food restaurant and it's available and it's cheap and easy."

Orthopedic surgeon David Heligman says that too much soda consumption has been a concern for teens for a long time now. It's been to everything from tooth decay to obesity. But there's other health concerns for this stuff as well. "The soft drinks can diminish some of the calcium in the bone."

Dr. Heligman also says that especially for women, as girls get older, lower calcium intake is a real problem, because adolescence is a critical period for accumulating peak bone mass. You want to do what you can to prevent osteoporosis. "You have a good healthy diet, you take your calcium supplements, you keep your weight in the reasonable range and those are the best things you can do to prevent osteoporosis."

Erin adds, "I have a yogurt every morning for breakfast because it is a great source of calcium."

Cheeses and calcium fortified orange juice are also good sources of calcium. So limiting your soda intake and replacing it with healthier choices is a good place to start.

Researchers also theorize that soda consumption may be related to other unhealthy eating habits, not surprisingly they found that the more soda girls drank, the more weight they gained.
