What to eat with braces?

Amoureux
I've gotten the huge list of what to avoid with braces (their rationalization being that lactic acid causes permanent white marks when the braces are removed), but I'm a huge soda drinker.

Most of my friends eat whatever they want, but is the whole white mark thing serious or just a rare case used to scare you? Is there anyone who has ever had these marks?
