Mozzarella is a versatile cheese that's flavorful in a variety of dishes, ranging from eggplant parmesan to caprese salad. Fresh mozzarella is softer and more moist than regular mozzarella. But with the exception of sodium, the nutrient content of both types of mozzarella is similar. Reduced-fat, part-skim regular mozzarella is available if you're trying to control your calories and weight.
