Fresh mozzarella is lower in sodium compared to many processed cheeses, but patients should still consult their healthcare provider or a dietitian for personalized advice.

Mozzarella is typically not aged for a long period; it is usually consumed fresh or within a few days of production. Fresh mozzarella is made to be enjoyed shortly after it's made, while some types, like aged mozzarella (mozzarella affumicata), may be aged for a few weeks to develop additional flavors.
