When you think of protein and calcium, you also think of healthy muscles and strong bones. Proteins are extremely important for muscle building and should therefore not be missing from a balanced diet.
Mozzarella with 45% fat in dry matter is a very protein-rich food with 18 grams of protein per 100 grams of cheese. For comparison: 100 grams of eggs, which are known as a source of protein, have "only" 13 grams of protein.
In addition to its protein content, it also has a high calcium content - the variant with 45% fat in dry matter contains around 400 mg per 100 grams of cheese.
