Do carbonated beverages such as soda help keep you hydrated? If so, how do they compare against water?

Carbonation is nothing more than carbon dioxide in solution. The body doesn't metabolize ingested CO2 (it tends to be released in burps), so it has no effect on the body's absorption or retention of water in the beverage.
