Parmesan cheese is often regarded as a safe option for lactose-intolerant individuals due to its low lactose content. Hard, aged cheeses like Parmesan typically contain minimal lactose because the lactose in the curd converts to lactic acid during aging. However, it's important to note that some lactose-intolerant people still experience adverse reactions to Parmesan, possibly due to varying tolerance levels or other components in the cheese, such as whey or histamines. Therefore, while Parmesan cheese is generally considered dairy, those with lactose intolerance should monitor their reactions and adjust their dairy intake accordingly.

What You'll Learn

Parmesan is low-lactose
Parmesan cheese is a hard, aged cheese that has a low lactose content. The process of aging hard cheeses means that the lactose in the curd is converted to lactic acid, resulting in a very low lactose level. This means that Parmesan is a safe option for those who are lactose intolerant and can be enjoyed without the usual symptoms associated with lactose intolerance.
Lactose is a natural sugar found in most dairy products. However, not all dairy foods contain lactose, and some have very low or negligible amounts. Parmesan cheese is one such example, as the aging process reduces the lactose content significantly. This makes Parmesan a suitable option for those who are lactose intolerant and looking to include dairy in their diet.
The level of lactose in Parmesan cheese can vary depending on the aging process and the type of Parmesan. Most Parmesan cheese averages around the two percent lactose threshold, but this can differ based on the duration and method of aging. The younger the cheese, the higher the lactose content, so it is important to consider the age of the cheese when assessing its lactose level.
While Parmesan is generally considered a low-lactose food, individual tolerance levels can vary. Some people with lactose intolerance may still experience symptoms when consuming Parmesan, as it does contain a small amount of lactose. Additionally, Parmesan is made from skimmed milk and contains whey, a protein that can cause symptoms similar to lactose intolerance. Therefore, it is important to understand your tolerance level and consume Parmesan in moderation if necessary.
For those who are highly sensitive to lactose, it is recommended to consult with a dietitian or health professional to determine the appropriate level of lactose for your diet. Adjustments can be made based on individual tolerance, and other low-lactose cheese options, such as Asiago and Romano, can be explored to find suitable alternatives.

Lactose intolerance and allergies
Parmesan cheese is derived from dairy, but it is considered lactose-free as it contains very low amounts of lactose. Lactose is a natural sugar found in dairy products, and individuals with lactose intolerance are unable to digest it due to the absence of the enzyme lactase. While lactose intolerance can cause discomfort, it is not life-threatening. Common symptoms include nausea, cramps, gas, bloating, and diarrhea. Lactose intolerance is more prevalent in adults, with approximately 30 million Americans affected by the age of 20. It is more common in individuals of Asian, African, or Native American descent and less common in those with northern or western European ancestry.
Lactose intolerance is distinct from a dairy allergy, which is an immune system malfunction. In a dairy allergy, the immune system identifies certain milk proteins, such as casein and whey, as harmful invaders and releases substances that trigger allergy symptoms. Dairy allergy can cause reactions in various parts of the body, including the skin and lungs, and it may lead to life-threatening anaphylaxis, characterized by throat swelling and breathing difficulties.
While Parmesan cheese is generally safe for individuals with lactose intolerance due to its low lactose content, it is important to remember that every lactose-intolerant individual has a unique tolerance level for dairy products. Some people may be unable to tolerate any lactose at all, so even cheeses with negligible amounts of lactose may not be suitable for them. Additionally, biological and enzymatic processes are not binary but continuous, so a theoretically "low-lactose" cheese like Parmesan can still have pockets of higher lactose content.
Furthermore, some individuals with lactose intolerance may experience symptoms after consuming Parmesan cheese due to a histamine allergy or sensitivity to the aging process. Aged cheeses tend to have higher histamine levels, which may trigger reactions in those allergic to histamines. Additionally, whey, one of the proteins in dairy, is added to Parmesan cheese, and some individuals may experience symptoms similar to lactose intolerance due to whey sensitivity.
If you are lactose intolerant or suspect a dairy allergy, it is essential to consult a healthcare professional for proper diagnosis and guidance. They can help determine your specific tolerance levels and provide recommendations for managing your condition, including dietary adjustments or the use of lactase pills to aid in lactose digestion.

Dairy-free alternatives
Parmesan cheese is made from dairy, specifically cow's milk. However, it is naturally very low in lactose, with most Parmesan cheese averaging around the two percent threshold, depending on how long it has been aged. This is because, during the aging process, the lactose in the curd changes to lactic acid. Therefore, Parmesan is a safe option for those who are lactose intolerant. However, some people with lactose intolerance may still experience symptoms after consuming Parmesan. This could be due to an allergy to histamines, which are present in high amounts in aged cheeses, or an allergy to whey, which is added to Parmesan during production.
If you are looking for a dairy-free alternative to Parmesan cheese, there are several recipes available that use plant-based ingredients to mimic the texture and flavor of Parmesan. Here are some options:
- Nut-based Parmesan: This alternative uses nuts such as cashews, almonds, walnuts, pine nuts, macadamia nuts, or a combination of these, to create a cheesy flavor and texture. The nuts are blended with nutritional yeast, salt, and optionally, onion or garlic powder, to taste. This recipe is dairy-free, egg-free, gluten-free, grain-free, peanut-free, soy-free, plant-based, and vegetarian. It can also be made nut-free by substituting sunflower seed kernels for the nuts.
- Vegan saltines: This option uses vegan saltines instead of nuts or seeds to create a dairy-free Parmesan alternative.
- Hemp seeds: This alternative uses hemp seeds and pine nuts to create a vegan Parmesan cheese.

Authentic Parmesan
Parmesan cheese is a hard, aged cheese that is naturally very low in lactose. This is because, during the ageing process, the lactose in the cheese is converted to lactic acid. As such, Parmesan is often considered a safe option for those who are lactose intolerant. However, it's important to note that not everyone with lactose intolerance can tolerate the same amount of lactose, and some people may react to even low-lactose cheeses.
The process of making Parmigiano Reggiano has remained unchanged for centuries. It begins with local milk, collected from cows grazing on fresh grass and hay in the meadows of Italy's Po Valley. The milk is then poured into copper-lined vats, where it is curdled and separated. The curds are cut, cooked, and then placed into circular moulds. Each wheel of cheese is brined for flavour and preservation before being left to age for at least 12 months.
The ageing process is what gives Parmigiano Reggiano its distinctive flavour and granular texture. During this time, the cheese is carefully monitored and graded, ensuring it meets the strict standards of its Protected Designation of Origin status. This status, granted by the European Union, guarantees that Parmigiano Reggiano can only be produced in this specific region of Italy, respecting traditional methods and ingredients.
So, when it comes to choosing Parmesan, opting for authentic Parmigiano Reggiano not only ensures a superior taste experience but also supports the preservation of traditional cheese-making practices.

Other low-lactose cheeses
Parmesan is a hard, aged cheese that is generally considered safe for people with lactose intolerance. However, some individuals with lactose intolerance have reported adverse reactions to Parmesan, which may be due to other components in the cheese, such as histamines or whey. It is important to note that lactose intolerance affects everyone differently, and some people may need to avoid all dairy products.
Now, let's move on to other low-lactose cheeses that can be enjoyed by those with lactose intolerance:
Cheddar
Cheddar is a versatile aged cheese with a sharp flavour that becomes more pronounced as it ages. The longer it is aged, the lower the lactose content, with some aged cheddars considered lactose-free by dietary standards. Cabot Creamery's naturally aged cheddars, for instance, have 0g of lactose per serving.
Gouda
Gouda is another cheese that becomes increasingly lactose-free as it ages. Look for varieties labelled as "aged" or "extra-aged" to find options with the lowest lactose content.
Gruyère
Gruyère is a low-lactose melting cheese that is perfect for those who enjoy the gooey goodness of melted cheese. It is an excellent alternative for those who miss having melted cheese due to their lactose intolerance.
Havarti
Havarti is a mild-flavoured cheese similar to Jack cheese. It has a low to non-detectable level of lactose, ranging from 0.1% to 2%. It is a great choice for sandwiches or melted on an omelette.
Limburger
Limburger is a soft, washed-rind cheese with a strong smell and flavour. Despite its strong aroma, it has a smooth, creamy texture that pairs well with crackers and bread. Limburger contains only a moderate amount of lactose, about 2%.
Feta
Feta is practically lactose-free, with only between 0.5% and 1.5% lactose. It is also lower in fat than many other cheeses, making it a healthier option for those with lactose intolerance.
In addition to these cheeses, Muenster, a semi-soft cheese from the United States, has a very low lactose range of 0% to 1.1%.
