Parmesan cheese is often considered a safe option for those who are lactose intolerant. This is because hard, aged cheeses like Parmesan, Asiago, and Romano, tend to be lower in lactose due to the extensive aging process that transforms lactose in the curd into lactic acid. However, some individuals with lactose intolerance have reported adverse reactions to Parmesan, which may be due to other components like whey or histamines, or the fact that some commercially available Parmesan cheeses are not authentic and may have higher lactose content.

What You'll Learn

Parmesan is low-lactose
Parmesan cheese is generally considered to be low-lactose, making it a good option for those who are lactose intolerant. Lactose is a sugar naturally found in dairy products, and lactose intolerance occurs when the body has difficulty breaking down this sugar due to a decrease in lactase production. This condition affects the digestive system and can cause severe digestive problems.
Hard, aged cheeses like Parmesan, Asiago, and Romano tend to be lower in lactose because, during the aging process, the lactose in the curd changes to lactic acid. The longer a cheese is aged, the less lactose it will contain. Parmesan cheese typically falls into the lactose range of zero to two percent, with the exact percentage depending on the aging duration.
While Parmesan is low in lactose, it's important to note that it is made from skimmed milk and whey, a dairy protein that can cause symptoms similar to lactose intolerance. For this reason, some lactose-intolerant individuals may still experience adverse reactions to Parmesan cheese. Additionally, aged cheeses contain high amounts of histamines, which may be another cause of negative reactions.
It's worth mentioning that other hard cheeses, such as cheddar, mature cheeses like Brie, Camembert, and Feta, and yogurt are also considered to have very low lactose content. These options may be suitable for those who find that Parmesan cheese triggers their lactose intolerance. Consulting with a dietitian or health professional is advisable to determine the best dietary choices for managing lactose intolerance.

Lactose intolerance
Lactose is a sugar found in milk and milk products. Lactose intolerance is a condition in which the body is unable to digest this sugar due to a deficiency of the lactase enzyme, which is normally produced in the small intestine. This condition is usually harmless but can cause uncomfortable symptoms such as diarrhea, gas, bloating, abdominal pain, and nausea. These symptoms typically occur within 30 minutes to 2 hours of consuming lactose.
The condition can be primary or secondary. Primary lactose intolerance is the most common type, where lactase production gradually decreases from infancy as milk is replaced with other foods. By adulthood, lactase production may have reduced significantly, leading to lactose intolerance. Secondary lactose intolerance is caused by an illness, injury, or surgery affecting the small intestine, or associated diseases such as intestinal infection, celiac disease, bacterial overgrowth, or Crohn's disease.
While there is no cure for lactose intolerance, symptoms can be managed through dietary adjustments. Most lactose-intolerant individuals can still consume some dairy products, especially those with low lactose content, such as hard and mature cheeses (including Parmesan, cheddar, and Swiss cheeses), and yogurt. The Australian Dietary Guidelines suggest that lactose-intolerant individuals may be able to tolerate up to 250 ml of milk spread throughout the day and consumed with other foods. Additionally, gradual introduction and increasing intake of milk may help build tolerance over time. It is important to consult with a healthcare professional or dietitian for tailored guidance.

Lactose in dairy products
Dairy products are a rich source of protein, calcium, and vitamins A and D. However, for people with lactose intolerance, consuming dairy can lead to severe digestive problems. Lactose intolerance occurs when the body struggles to break down lactose, a natural sugar found in dairy products. While most cheeses are naturally lactose-free or contain very low levels of lactose, other dairy products such as milk, butter, and yogurt are high in lactose.
Hard and mature cheeses, such as Parmesan, cheddar, and Swiss cheese, are generally well tolerated by people with lactose intolerance. This is because the cheese-making process involves separating milk into whey and curds, and most of the lactose is found in whey, which is removed. The remaining lactose in the curds is converted into lactic acid during the aging process, further reducing the lactose content.
However, it's important to note that not everyone with lactose intolerance can consume these cheeses without issues. Some people may still experience symptoms, possibly due to the presence of whey or other compounds in the cheese. Additionally, the lactose content can vary depending on the type of cheese and the length of aging. For example, Swiss cheeses tend to have higher lactose levels, while authentic Parmesan cheese is known for its low lactose content.
For people with lactose intolerance, it's essential to find the right balance of dairy consumption that works for them. They can adjust their intake based on their tolerance levels and explore other lactose-free options. Lactase enzyme tablets are also available to aid in lactose digestion, allowing people with lactose intolerance to enjoy a wider range of dairy products.
In summary, while hard and mature cheeses are generally low in lactose, individual tolerance may vary. People with lactose intolerance should consult with a dietitian or health professional to determine their specific needs and safely include dairy in their diet.

Lactose-free diets
Lactose is a sugar that is typically found in milk and milk products. It is broken down by lactase, an enzyme in the small intestine. However, some people are unable to produce lactase, resulting in an inability to digest lactose. This condition is known as lactose intolerance, and it affects approximately 65% of the world's population.
A lactose-free diet eliminates or restricts lactose and can help minimize the symptoms of lactose intolerance. This diet involves avoiding all foods that contain lactose, including milk, cheese, butter, yogurt, and other dairy products. It is important to read labels and look for added milk or dairy products, such as milk solids, whey, or milk sugar. Even some non-dairy products like margarine, baked goods, and salad dressings can contain lactose.
However, it is important to note that not all dairy needs to be eliminated from a lactose-free diet. Some dairy products have very low levels of lactose or contain beneficial bacteria that can aid in lactose digestion. Hard and mature cheeses, such as cheddar, parmesan, and feta, contain almost zero lactose due to the way they are made and aged. Yogurt is another option, as it contains bacteria that break down lactose over time, even when stored in the fridge. Additionally, there are many lactose-free and lactose-reduced dairy products available, including milk, ice cream, and cheese.
For those following a lactose-free diet, there are still plenty of healthy food options available. Fruits, vegetables, whole grains, nuts, seeds, and legumes can all be easily incorporated into a lactose-free diet. It is also important to consider calcium and vitamin D intake, as these nutrients are typically obtained from dairy products. Consult with a healthcare provider or dietitian to ensure your nutritional needs are being met.

Lactose intolerance symptoms
Parmesan cheese is generally considered to be low in lactose. Hard, aged cheeses like Parmesan frequently contain less lactose because the lactose in the curd changes to lactic acid during aging. However, some people with lactose intolerance have reported experiencing symptoms after consuming Parmesan. This could be due to the presence of whey, a protein in dairy that can cause symptoms similar to lactose intolerance, or a reaction to histamines, which are found in high amounts in aged cheeses.
Now, onto the symptoms of lactose intolerance. People with lactose intolerance are unable to fully digest the sugar (lactose) in milk due to a deficiency of the enzyme lactase, which is produced in the small intestine. This deficiency can be caused by a variety of factors, including genetics, age, illness, injury, or surgery involving the small intestine. Lactose intolerance is most common in Asian Americans, African Americans, Mexican Americans, and Native Americans.
The symptoms of lactose intolerance usually begin within 30 minutes to two hours after consuming foods or drinks containing lactose. Common symptoms include diarrhea, gas, bloating, abdominal cramps, and nausea. While the condition is typically harmless, these symptoms can be uncomfortable. The severity of symptoms depends on the amount of lactose consumed and the individual's lactase levels.
There is no cure for lactose intolerance, but symptoms can be managed through diet changes. People with lactose intolerance can experiment with different dairy foods to find the ones that cause fewer symptoms. Hard and mature cheeses, as well as yogurt, are good options as they have very little lactose. Additionally, people with lactose intolerance can try gradually increasing their milk intake to build up their tolerance, starting with small amounts to see how their body reacts.
