What You'll Learn

Parmesan is mostly safe for those with lactose intolerance
The younger the cheese, the more lactose it contains. Fresh and unripened cheeses contain more lactose, so those with lactose intolerance should avoid creamier cheeses like ricotta and cottage cheese. These cheeses are high in lactose because they are so fresh.
While Parmesan is mostly safe for those with lactose intolerance, it is important to remember that every lactose intolerant individual has a different tolerance level for dairy products. Some people cannot handle any lactose at all, so even low-level cheeses may not be safe for them. However, small amounts of any kind of cheese are typically tolerated well by those with lactose intolerance.
For those who are lactose intolerant, eating ingredients that have high levels of lactose can cause some very uncomfortable digestive issues, from bloating and gas to cramping and serious stomach pain. Parmesan is a hard, aged cheese, so it contains very low levels of lactose, making it mostly safe for those with lactose intolerance.

Lactose content depends on the aging process
Lactose intolerance affects a large portion of the world's population, with some estimates placing it at around 65%. This condition is characterized by an inability to digest lactose into glucose and galactose, resulting in various gastrointestinal issues. Fortunately, there are cheeses that are lower in lactose and can be enjoyed by those with this intolerance.
The lactose content of cheese depends on several factors, one of which is the aging process. As a general rule, hard and aged cheeses tend to have lower lactose levels. During the aging process, the lactose in the cheese changes to lactic acid, resulting in reduced lactose content over time. This means that older cheeses will generally have lower lactose levels than their younger counterparts.
For example, Parmesan cheese, which is often aged for 12 to 36 months, is known for having very low levels of lactose. It is considered safe for most individuals with lactose intolerance, though the tolerance levels can vary among individuals. Similarly, aged cheddar, which can be aged for up to five years, has lower lactose content than mild cheddar, which is typically aged for only two to three months.
Other examples of aged cheeses with low lactose content include Provolone, Emmenthaler, and Gruyère. These cheeses have undergone a significant aging process, reducing their lactose levels and making them more digestible for those with lactose intolerance.
While aged cheeses generally have lower lactose levels, it's important to note that individual tolerance levels can vary. Some people with lactose intolerance may still experience discomfort even with low-lactose cheeses. Additionally, other factors such as fat content and milk allergies may also play a role in triggering negative reactions. Therefore, it is always advisable to consult a healthcare professional or a registered dietitian for personalized advice and to determine one's tolerance levels.

Other lactose-free cheeses
Parmesan cheese is generally considered lactose-free due to its low lactose content, which typically falls within a safe lactose range of zero to two percent. This is because, during the aging process, the lactose in the curd changes to lactic acid, reducing the overall lactose content.
Asiago and Romano
Like Parmesan, Asiago and Romano cheeses are hard, aged cheeses that are naturally lactose-free due to the aging process.
Cheddar
Cheddar cheese is often mentioned as a lactose-free option. Cabot, a cheese manufacturer, produces award-winning aged cheddar cheeses that contain 0 grams of lactose per serving. Their cheeses, including Pepper, Colby, Colby Jack, and Muenster, are considered to be nearly lactose-free, with very low levels of lactose per serving (less than 0.1 grams per 1-ounce serving).
Gouda
Gouda is another cheese that has been specifically mentioned as a safe option for those with lactose intolerance. Cabot also produces lactose-free Gouda cheese.
Swiss
Swiss cheese is generally well-tolerated by those with lactose intolerance. While it is made with cow's milk, it is considered a good option for those who cannot digest lactose.
Feta
Feta cheese is practically lactose-free, with only between 0.5% and 1.5% lactose. It is also lower in fat than many other types of cheese and is a good source of essential vitamins and minerals, including riboflavin, phosphorus, and selenium.
Limburger
Limburger is a soft, washed-rind cheese with a strong smell and flavor. It contains only about 2% lactose, making it a moderate option for those with lactose intolerance. Its creamy texture pairs well with crackers and bread.
Camembert and Brie
These soft, creamy cheeses have a lactose range of 0-1.8% and 0-2%, respectively, making them lower-lactose options that can be enjoyed in moderation.
It is important to remember that every individual with lactose intolerance has a unique tolerance level for dairy products. While some may be able to tolerate small amounts of lactose, others may need to avoid it completely.

Lactose intolerance and its effects
Lactose intolerance is a condition characterized by an individual's inability to digest lactose, a sugar found in milk and milk products. The condition is caused by the small intestine's insufficient production of the enzyme lactase, which is responsible for breaking down lactose into glucose and galactose for absorption into the bloodstream. Lactose intolerance can lead to various uncomfortable symptoms, including bloating, gas, abdominal pain, diarrhea, and nausea. These symptoms typically occur within a few hours of consuming lactose-containing foods and can vary in severity depending on the amount of lactose consumed and individual tolerance levels.
The good news for cheese lovers who are lactose intolerant is that not all cheese needs to be off the menu. Aged, hard cheeses, such as Parmesan, tend to have lower lactose levels, making them easier to digest. This is because, during the aging process, lactose in the curd changes to lactic acid, reducing the overall lactose content. However, it's important to remember that while some cheeses may be safer choices, they can still contain small amounts of lactose.
For those with lactose intolerance, the key to managing symptoms is to avoid or limit lactose consumption. This may involve reducing or eliminating dairy products, which are the primary source of lactose in the diet. Lactose-intolerant individuals can also opt for lactose-free or low-lactose alternatives, such as lactose-free milk and aged cheeses. Additionally, dietary supplements containing lactase enzymes can be taken with lactose-containing meals to aid in digestion and reduce symptoms.
It is worth noting that lactose intolerance is distinct from a milk allergy, which is an immune response to milk proteins. Lactose intolerance is also different from irritable bowel syndrome (IBS), although they can share similar symptoms. If you suspect you have lactose intolerance, it is advisable to consult a healthcare professional for proper diagnosis and guidance on managing your symptoms.
While lactose intolerance can be a challenge, with the right knowledge and strategies, individuals can still enjoy their favorite foods and maintain a healthy, well-balanced diet.

Lactose intolerance and milk allergies are different
Parmesan cheese averages around the two percent lactose threshold, depending on its age. Generally, the longer a cheese has been aged, the less lactose it will contain. This is because the lactose in the curd changes to lactic acid during the aging process. Therefore, aged Parmesan cheese is a good option for those who are lactose intolerant.
Lactose intolerance is a common condition, with around two-thirds of the world's population affected. It is more prevalent in people with Asian, African, or Native American heritage. Lactose intolerance is a digestive problem caused by the body's inability to produce enough of the enzyme lactase, which is needed to digest lactose, a sugar found in milk and dairy products. As a result, those with lactose intolerance may experience symptoms such as nausea, cramps, gas, bloating, and diarrhea. However, it is important to note that lactose intolerance is not life-threatening.
On the other hand, a milk allergy is an immune system reaction to the proteins found in milk. It occurs when the immune system overreacts to a specific food protein. Milk allergy is one of the most common allergies, especially in infants and young children. Symptoms of a milk allergy may include nausea, diarrhea, and abdominal pain, similar to lactose intolerance. However, a milk allergy can also cause reactions in other parts of the body, such as the skin and lungs, and can lead to a severe, life-threatening allergic reaction called anaphylaxis.
While there may be some overlap in symptoms, lactose intolerance and milk allergies are distinct conditions with different underlying causes and mechanisms. Lactose intolerance is a carbohydrate intolerance, whereas a milk allergy is an immune response. They also have different diagnostic tests, treatments, and dietary restrictions. Those with lactose intolerance may be able to tolerate small amounts of lactose and can find lactose-free or lactose-reduced options, whereas those with a milk allergy typically need to avoid all milk and dairy products.
