Does Diet Coke have salt in it?

Yes, Diet Coke does have salt in it. The amount of salt in Diet Coke varies depending on the country where it is sold, but it typically contains around 10 milligrams of sodium per 12-ounce can. This is a relatively small amount of salt, and it is not enough to cause health problems for most people. However, people who are on a low-sodium diet may want to avoid drinking Diet Coke, as the sodium content can add up over time.
