Parmesan cheese is rich in nutrients, especially calcium and protein. It can help prevent osteoporosis due to its high calcium content and is beneficial for maintaining healthy blood pressure. Parmesan is naturally lactose-free, making it suitable for those with lactose intolerance. However, people with a casein allergy should avoid it as it can cause allergic reactions. Additionally, due to its high calorie content, it should be consumed in moderation to avoid weight gain.
