Cheese substitute, mozzarella vs Sour cream, fat free

Sour cream, fat free, is the stronger nutrient-density performer here, scoring 59 of 100 versus 49 for cheese substitute mozzarella. The clearest differences are calories and sugar: fat free sour cream has just 74 calories per 100 g against 248 for the mozzarella substitute, and only 0.39 g of sugar compared with 23.7 g. Sodium is also lower at 141 mg versus 685 mg, though the mozzarella substitute has nearly four times the protein at 11.5 g against 3.1 g.

Choose fat free sour cream when you want a lighter, lower-sugar, lower-sodium option for toppings or dips. Choose the mozzarella substitute when protein per serving matters more than calorie count, such as in a melted cheese application. The trade-off is straightforward: more protein but far more sugar, fat, and sodium on the cheese substitute side.
