Non-Alcoholic Beer for Post-Op? Is it OK to have?

Anybody have any advice on Non-Alcoholic Beer? Is it safe to drink? I know it has a few less calories and carbs than regular light beer. But does anyone know if there is any potential danger for using this as a substitute? Any advice would be appreciated.
