What You'll Learn
Parmesan is naturally low-lactose
Parmesan cheese is often considered the "'king of cheeses'", and for good reason. Not only is it full of flavour, but it is also naturally low-lactose, making it an excellent option for those with lactose intolerance.
The process of fermentation breaks down the lactose in cheese over time, resulting in lower lactose levels as the cheese matures. This is why aged cheeses, like Parmesan, are often well-tolerated by individuals with lactose intolerance. In fact, Parmesan cheese typically averages around the two per cent lactose threshold, depending on how long it has been aged. Some varieties are matured for so long that almost all their lactose breaks down, resulting in a product that is very low in lactose.
However, it is important to remember that not all Parmesan cheese is created equal. The younger the cheese, the more lactose it contains. To ensure that your Parmesan is completely lactose-free, check the product label. Additionally, individual tolerance levels vary, so it is always best to start with small amounts and monitor your body's response.
For those with lactose intolerance, Parmesan cheese can be a delicious and safe option. Its long aging process not only contributes to its distinctive flavour but also results in a product that is naturally low in lactose. So, if you're looking to indulge in a tasty treat without the worry of lactose intolerance symptoms, Parmesan cheese is a great choice.

Lactose intolerance and individual tolerance levels
Lactose intolerance is the inability of the body to digest lactose, a sugar found in milk and other dairy products. It occurs when the small intestine does not produce enough lactase, the enzyme needed to break down and absorb lactose. Lactose intolerance can be classified as primary, secondary, congenital, or developmental, depending on the underlying cause and age of onset.
The severity of lactose intolerance varies among individuals, and some people can tolerate small amounts of lactose without experiencing any adverse effects. The level of tolerance can depend on factors such as health status and pregnancy. Lactose intolerance is also more prevalent in certain ethnic groups, including Asian Americans, African Americans, Mexican Americans, and Native Americans.
Parmesan cheese is often considered a safe option for people with lactose intolerance due to its low lactose content. The aging process of hard cheeses like Parmesan reduces lactose levels, converting lactose in the curd into lactic acid. However, it's important to remember that individual tolerance levels vary, and some people with lactose intolerance may still experience symptoms even with low-lactose cheeses like Parmesan.
For those with lactose intolerance, managing symptoms typically involves limiting lactose intake to tolerable levels. Lactose-free and lactose-reduced dairy products are available, and lactase supplements can also aid in lactose digestion. Additionally, certain types of cheeses naturally have lower lactose levels, including hard cheeses like Asiago and Romano, and some varieties of Gouda and Provolone.
While Parmesan and similar cheeses are generally well-tolerated by those with lactose intolerance, individual experiences may vary. Some people may still experience symptoms due to the presence of whey or histamines in the cheese, or they may have a dairy allergy or sensitivity to aged cheeses. It is always advisable to consult a healthcare professional for guidance on managing lactose intolerance and determining one's specific tolerance levels.

Other low-lactose cheeses
Parmesan is often considered a safe option for those who are lactose intolerant. This is because, as cheese ages, any remaining lactose continues to break down, resulting in lower lactose levels over time. Parmesan is aged for a long time, and so it contains minimal lactose.
However, some people with lactose intolerance can still have adverse reactions to Parmesan. This may be because biological and enzymatic processes are uneven, and so a "low-lactose" cheese can still have pockets of higher lactose content. It may also be because they are allergic or sensitive to dairy or the ageing process, or because Parmesan contains whey, which can cause symptoms similar to lactose intolerance.
If you are lactose intolerant and looking for cheese alternatives, there are several options with low lactose levels that are safe to eat. In general, hard, aged cheeses frequently contain less lactose because the lactose in the curd changes to lactic acid during ageing. So, cheeses like Asiago, Romano, and Cello's Parmesan, Asiago, and Romano are good options.
- Muenster, a semi-soft cheese with a mild, slightly nutty flavour, typically made with cow's milk, which has a 0-1.1% lactose range.
- Cheddar, which has very little to no lactose per serving (less than 0.1 grams per 1oz serving).
- Gouda, a dense, nutty, and sweet cheese made from cow's milk. Most Gouda falls between a zero and two per cent lactose range.
- Provolone, a firm, grainy cheese, usually made from cow's milk, with a pale-yellow colour and a waxy rind. Most Provolone has less than two per cent lactose.
- Feta, which is practically lactose-free (with only between 0.5% and 1.5% lactose) and is also lower in fat than many other cheeses.
- Limburger, a soft, washed-rind cheese with a strong smell and flavour, which has a moderate amount of lactose (about 2%).
- Havarti, which has a low to non-detectable level of lactose (around a 0.1% to 2% lactose range).

Lactose-free labelling
Parmesan cheese is generally considered to be low-lactose, with most varieties averaging around 2% lactose content. This is because, during the ageing process, the lactose in the curd is converted into lactic acid. As a result, older, harder cheeses like Parmesan tend to be lower in lactose than younger, softer, creamier cheeses.
However, it's important to note that not all lactose-intolerant individuals can tolerate the same levels of lactose, and some may experience symptoms even from low-lactose cheeses like Parmesan. Additionally, the presence of whey in Parmesan, which is a protein found in dairy, may also contribute to symptoms similar to lactose intolerance.
When it comes to lactose-free labelling, there are a few key considerations. Firstly, it's important to understand the distinction between lactose-free and dairy-free products. Lactose-free products do not contain any lactose, but they may still contain dairy, including milk proteins. On the other hand, dairy-free products do not contain any dairy, but they may still contain lactose.
In the United States, the FDA has specific guidelines for labelling lactose-free products. Manufacturers must list all ingredients in descending order of percentage and total weight, and clearly indicate the presence of any of the 14 common food allergens, including milk, eggs, and wheat. However, there is no FDA definition for lactose-free since lactose intolerance is not considered an allergy. Instead, manufacturers must accurately list all ingredients, including any sources of lactose.
In the European Union, there are currently no EU-wide rules regarding the labelling of lactose-free products. As a result, manufacturers can set their own thresholds for labelling foods suitable for lactose-intolerant individuals, leading to variations in the level of protection offered to consumers across different countries.
To ensure compliance with regulations and provide clear information to consumers, manufacturers can utilise label design and printing services that offer expertise in lactose-free labelling. This includes creating custom labels that accurately list ingredients and highlight relevant allergens.

The ageing process and its effects on lactose content
Parmesan cheese is made from unpasteurized cow's milk and undergoes a meticulous ageing process to achieve its distinct characteristics. The ageing process, which can last from 12 to over 36 months, is crucial for developing the cheese's flavour, texture, and nutritional profile. During this process, the lactose in the cheese is broken down, rendering it virtually lactose-free. This makes Parmesan accessible to those with lactose intolerance.
The younger the cheese, the more lactose it contains. Fresh and unripened cheeses tend to have higher lactose levels, while aged cheeses have lower lactose content. This is because, over time, the lactose in the curd is converted into lactic acid. As a result, aged cheeses like Parmesan are often compared favourably to unprocessed cheese, which is marketed for retaining the natural qualities of milk.
While Parmesan is known for its low lactose content, some individuals with lactose intolerance may still experience symptoms after consuming it. This may be due to variations in the cheese's lactose content or individual tolerance levels. Additionally, aged cheeses can contain high levels of histamines, which can trigger allergic reactions in some people.
The ageing process not only reduces lactose content but also enhances the nutritional profile of Parmesan. As the cheese ages, its proteins decompose into free amino acids, contributing to its umami flavour. The concentration of proteins, calcium, and vitamins increases, making Parmesan a nutritious addition to a balanced diet. The high content of essential amino acids supports muscle repair and growth, while the calcium promotes bone health.
In summary, the ageing process significantly impacts the lactose content and overall quality of Parmesan cheese. The breakdown of lactose during ageing not only makes the cheese accessible to lactose-intolerant individuals but also enhances its flavour and nutritional benefits. However, individual variations in lactose tolerance and potential allergies to other compounds in aged cheese can still cause adverse reactions in some people.
