What You'll Learn

Parmesan cheese is a rich source of calcium
Parmesan, also known as Parmigiano-Reggiano, is a versatile cheese enjoyed in a variety of dishes, from appetizers to desserts. It is typically sold shredded, grated, or in wedges and can be found in stores and online. While its flavour can vary depending on its ripening time, it is often characterised by a strong, nutty taste that can be sweet, salty, and bitter.
One of the most notable nutritional qualities of Parmesan cheese is its high calcium content. Calcium is essential for maintaining strong and healthy bones, especially as we age. Parmesan cheese is an excellent source of this vital mineral, providing at least a quarter of the daily recommended value in a single serving. This makes it a great option for individuals who may not consume other calcium-rich foods like milk as they get older.
Additionally, the calcium in Parmesan cheese has high bioavailability due to its casein content. This means that it is easily absorbed by the body. The digestion of casein leaves mineral residues that further enhance the absorption of calcium, as well as other important minerals like iron and zinc. As a result, Parmesan cheese is not just a tasty addition to meals but also a functional food that may contribute to improved health and reduced disease risk.
When purchasing Parmesan cheese, it is important to choose high-quality options to ensure maximum nutritional benefits. While cheaper, mass-produced varieties may be more readily available, they often contain fillers and additional ingredients that can impact the overall nutritional value. Opting for authentic Parmigiano-Reggiano cheese, which is recognised as 100% natural, can provide the full range of nutritional benefits that this cheese has to offer.

It is also a good source of protein
Parmesan cheese, or Parmigiano-Reggiano, is a hard Italian cheese with unique nutritional qualities. It is well-known for its strong, nutty flavour that can be sweet, salty, and bitter.
Parmesan is a good source of protein. In fact, it provides large amounts of high-quality protein because it contains high concentrations of all the essential amino acids. Amino acids are the building blocks of protein, and essential amino acids are those that our bodies cannot produce and must be obtained from food. The protein in Parmesan is also easy to digest. During the maturation period, the proteins in the cheese undergo a process similar to pre-digestion, making it a complete protein.
The Consortium, which periodically tests random samples of Parmigiano-Reggiano, has confirmed that the maturation process does not affect the lactose content in the cheese. This means that Parmesan remains a good source of protein even as it ages.
The high protein content in Parmesan cheese is due to its manufacturing process, which is over 1000 years old. This traditional process results in the cheese's characteristic flavour and texture. However, it is important to note that the mass-produced nature of some Parmesan cheeses may impact their nutritional value. The addition of fillers and ingredients to prevent clumping can reduce the amount of protein in cheaper brands.
Overall, Parmesan cheese is a nutritious and versatile ingredient that can enhance a variety of dishes, from appetizers to desserts. Its high protein content makes it a valuable component of a balanced diet.

The calcium in Parmesan has high bioavailability
Parmesan, or Parmigiano-Reggiano, is a hard Italian cheese with unique nutritional qualities. It is a rich source of calcium and protein and is easily digestible. The calcium in Parmesan has high bioavailability, meaning it is easily absorbed by the body. This is due to the cheese's casein content; when casein is digested, it leaves mineral residues that enhance the absorption of other minerals such as calcium, iron, and zinc.
Parmigiano-Reggiano is a natural cheese made up of 30% water and 70% nourishing substances. A 25-gram serving for an adult following a healthy and balanced diet of 2000 calories provides 36% of the daily calcium requirement. This is especially beneficial for sustained bone health, as calcium intake tends to decrease with age.
The maturation process of Parmesan also contributes to its high bioavailability. During maturation, the proteins in the cheese undergo a pre-digestion process, making them easier to digest. This, along with the absence of lactose, makes Parmesan a good option for those who are lactose intolerant.
The traditional manufacturing process of Parmigiano-Reggiano, which is over 1000 years old, results in its characteristic flavor and texture. However, it is important to note that the mass-produced nature of some Parmesan cheeses may affect their nutritional content. The addition of fillers and ingredients to prevent clumping can reduce the amount of calcium and protein present in the cheese. Therefore, consumers should be mindful of the quality and source of their Parmesan to ensure they are receiving the full nutritional benefits.

Parmesan is a lactose-free cheese
Parmesan, also known as Parmigiano-Reggiano, is a hard Italian cheese with unique nutritional qualities. It is a lactose-free cheese that is rich in calcium and contains high-quality, easily digestible protein. The Italian Ministry of Health has declared that dairy products with a lactose content of less than 0.1g/100g can be labelled as lactose-free. Parmigiano Reggiano falls under this category, as it is made without the use of additives and preservatives and only contains milk, salt, and rennet.
The lactose-free nature of Parmesan is a result of its traditional manufacturing process. During the first 48 hours of production, lactose, a sugar normally present in milk, is fermented by the microflora of lactic acid bacteria, turning it into lactic acid. This process, known as lactic fermentation, naturally removes lactose from the cheese.
The Consortium, which periodically tests random samples of Parmigiano Reggiano, has confirmed through their testing that the maturation process does not affect the lactose content of the cheese. Additionally, they have created a graphic symbol, "100% natural," to remind consumers that Parmigiano Reggiano is not only lactose-free but also free of preservatives.
The absence of lactose in Parmesan makes it a suitable option for individuals with lactose intolerance. While the tolerance levels vary among those with lactose intolerance, Parmesan generally contains low enough levels of lactose to be safely consumed. The longer a cheese ages, the less lactose it tends to contain, and Parmesan undergoes an extensive aging process, contributing to its lactose-free quality.
In summary, Parmesan, or Parmigiano-Reggiano, is a lactose-free cheese that offers a range of nutritional benefits, including high-quality protein and calcium. Its lactose-free nature is a result of its traditional manufacturing process and extensive aging, making it a viable option for individuals with lactose intolerance.

Grated Parmesan may contain fillers, impacting calcium content
Parmesan cheese is a hard Italian cheese with a nutty flavour that is rich in calcium and protein. It is typically sold shredded, grated, or in wedges. Grated parmesan cheese may contain fillers and additional ingredients to prevent clumping during the manufacturing process. While these fillers are generally considered harmless, there have been concerns about the accuracy of their reported quantities on nutrition labels.
The addition of fillers can impact the overall calcium content of grated parmesan cheese. Calcium is an essential mineral for bone health, and parmesan is known for its high calcium bioavailability, meaning it is easily absorbed by the body. However, if the actual amount of cheese in a product is lower than stated due to the presence of fillers, the calcium content may be lower than expected.
Some experts have expressed concern over the varying levels of cellulose found in cheaper brands of grated parmesan cheese. In some cases, the amount of cellulose was reported to be up to 10%, significantly higher than the listed amount of 4% or less. This discrepancy raises questions about the accuracy of nutrition labels and the actual amount of cheese in the product.
The type of milk used in the production of grated parmesan cheese may also impact its calcium content. If the milk does not come from grass-fed cows, the cheese may be less nutritious overall, including lower levels of calcium. Choosing a higher-quality product, such as Parmigiano-Reggiano, can help ensure a safer and more nutritious option with fewer fillers and a higher calcium content.
Overall, while grated parmesan cheese may contain fillers, the impact on its calcium content depends on the specific product and its ingredients. It is important for consumers to be aware of the potential variations in calcium levels and choose products with accurate labelling and higher nutritional values.
