Cheese vs Milk Lactose Comparison

Cheese and milk are two popular dairy products consumed by many individuals worldwide. Both offer unique flavors and nutritional benefits, but they differ in terms of lactose content. Lactose is a natural sugar found in milk, and its presence can affect individuals who are lactose intolerant. In this article, we will compare cheese and milk in terms of their lactose content, exploring how the cheese-making process affects lactose, lactose intolerance, and suitable options for individuals with lactose sensitivity.


Milk is a nutrient-rich liquid produced by mammals, such as cows, goats, or sheep, to feed their young. It contains various essential nutrients, including proteins, fats, vitamins, and minerals. Milk also naturally contains lactose, a sugar composed of glucose and galactose. Lactose is digested by an enzyme called lactase, which breaks it down into these simpler sugars for absorption.


Cheese is a dairy product made by curdling milk and separating the solid curds from the liquid whey. The curdling process involves the use of starter cultures and enzymes, such as rennet, to coagulate the milk proteins. During this process, lactose is partly converted into lactic acid by the bacteria in the starter cultures. The solid curds are then further processed, shaped, and aged to create various types of cheese.

Lactose Content:

Due to the cheese-making process, lactose content in cheese is significantly reduced compared to milk. The conversion of lactose into lactic acid by bacteria during the fermentation process helps break down lactose, resulting in lower lactose levels in cheese. As a result, many types of cheese have minimal lactose content, making them potentially more tolerable for individuals with lactose intolerance.

Lactose Intolerance:

Lactose intolerance is a condition characterized by the inability to fully digest lactose due to insufficient lactase enzyme production. This can lead to digestive symptoms such as bloating, gas, diarrhea, and stomach discomfort after consuming lactose-containing products. While individuals with lactose intolerance may experience discomfort when consuming milk due to its higher lactose content, they may find some types of cheese more manageable because of their lower lactose levels.

Suitable Cheese Options:

Certain types of cheese are typically lower in lactose and may be more suitable for individuals with lactose intolerance. These include aged cheeses like cheddar, Swiss, Parmesan, and Gouda, as well as blue cheeses. These cheeses undergo longer aging processes, allowing bacteria to convert more lactose into lactic acid. However, it’s important to note that individual tolerance to lactose can vary, and some people with severe lactose intolerance may still need to limit or avoid cheese consumption altogether.


Cheese and milk differ in terms of lactose content, with cheese generally having lower lactose levels due to the fermentation and aging processes involved in cheese-making. This makes certain types of cheese more tolerable for individuals with lactose intolerance. However, it’s important for individuals with lactose sensitivity to understand their own tolerance levels and consult with a healthcare professional or registered dietitian to determine suitable options for their specific needs. By being aware of lactose content in dairy products, individuals can make informed choices and still enjoy the flavors and nutritional benefits of dairy products like cheese and milk.
