When you pour soda into a glass, is the head / froth / bubbly stuff at the top actual soda that is being turned into froth and then wasted?

I have a debate with my girlfriend. I say that when she pours soda into a glass without tipping it, the head / froth / bubbly stuff that fills half the glass and then disappears downward is actual soda that is somehow combining with air and being wasted when it disappears.
She says that it's not soda, it's just something that comes out of the soda when you pour it that way.
