Beer and sparkling wine, while not artificially carbonated, are also major culprits for aerophagia.
Other chewy foods and candy, like fruit leathers or caramel, will cause you to swallow air as well.

Smoking products other than tobacco can also cause you to swallow air. It is the smoking mechanic, rather than the substance that causes aerophagia.
There are also ways to prevent hyperventilation, like exercising more frequently and breathing through your nose.
