Is Sodium an Enemy?

I find it super convenient to eat ready-made packaged meals for lunch. I normally do Healthy Choice or Smart Ones fduring the week. I like them because they are typically less than 300 calories and tasty, but I've noticed they have an insane amount of sodium....is this okay as long as I drink my 8 cups of water? Any other quick & convenient hot lunch ideas to eat when leftovers aren't available?
