What You'll Learn
Some cheeses are a good source of probiotics
Cheese is an excellent source of probiotics and living microorganisms that support gut health and overall well-being. The human gut contains about 100 trillion bacteria, and eating foods that contain probiotics, such as cheese, can help restore the natural balance between good and bad bacteria. Probiotics found in cheese can also strengthen the immune system by maintaining a healthy balance of good bacteria in the gut.
Trillions of microbes inhabit the digestive tract and play a crucial role in maintaining health by aiding digestion, producing vitamins, and protecting the body from harmful pathogens. Cheese's fermentation process makes it easier for the body to absorb nutrients. Aged, ripened, and propionic acid-fermented cheeses have higher concentrations of beneficial bacteria. Raw milk cheese, like Gouda, cheddar, and Roquefort, contains live cultures that promote good gut bacteria. Gouda is considered one of the best options due to its exceptional bacterial content. The longer a cheddar is aged, the more complex its flavor becomes and the higher the concentration of good bacteria it contains.
Other good sources of probiotics include Swiss cheese, known for its distinctive holes or "eyes," which has high levels of Propionibacterium freudenreichii, a helpful type of microbe that supports digestion and overall gut health. Gruyere, similar to Swiss cheese in texture but with a slightly nuttier flavor, is another excellent source of beneficial bacteria due to its traditional production methods using raw milk and long aging periods. Parmesan, a hard Italian cheese, contains strains of Lactobacillus rhamnosus, which can also help support gut health. Look for authentic Parmigiano-Reggiano made from raw milk for the best results.
While cheese is a good source of probiotics, it is important to consume it in moderation. Cheese tends to be high in calories, saturated fat, and sodium.

Cheese may harm gut health
Cheese is a dairy product that contains a variety of nutrients, including calcium, protein, vitamins, and minerals. While some types of cheese, such as Swiss and Gouda, are known to be a good source of probiotics, which can provide benefits to gut health, recent studies suggest that cheese may also have a detrimental effect on gut health.
The impact of diet on gut microbiota has been an emerging topic of research, with dietary intake being a key pathway by which gut health may be influenced. While the overall impact of dairy consumption on gut microbiota composition is still unclear, recent studies have found that different types of dairy products may affect the gut microbiome differently.
In a study published in the journal Nutrients, researchers found that drinking more milk was associated with an increase in two types of bacteria that may support gut health, while consuming more cheese was linked to lower amounts of another beneficial type of bacteria. This suggests that while milk may boost gut health, cheese may have the opposite effect. The study analyzed colonic mucosal biopsies and found that participants who consumed more dairy and milk and less cheese had higher alpha-microbial diversity, indicating a healthier gut ecosystem.
Another study reported that milk intake may modulate the gut microbiota composition favorably, while cheese consumption did not prompt any changes to the gut microbiota. This study highlights the potential impact of dairy products on gut health, but more research is needed to understand the broader health implications. It is worth noting that the process of pasteurizing cheese differs from that of milk, and the involvement of different bacteria in these processes may contribute to their varying effects on gut health.
While the research suggests that cheese may harm gut health by reducing beneficial bacteria, it is important to consider other factors that influence the structure and function of the gut microbiota, such as genetics, age, sex, and medication use. Additionally, the impact of cheese on gut health may vary depending on the type of cheese and the individual's overall diet and health. Further studies are needed to fully understand the complex relationship between cheese consumption and gut health.

Fermented cheeses positively impact gut health
Fermented cheese is a dairy product that contains a variety of nutrients, including calcium, protein, vitamins A and B12, and minerals like phosphorus and zinc. It is also a source of probiotics, which are beneficial live bacteria that can positively impact gut health.
Probiotics in fermented cheese contribute to a healthy balance of gut flora, supporting the growth of "good" bacteria. This can lead to improved digestion and a strengthened gut barrier, reducing the risk of leaky gut syndrome and inflammation. The process of fermentation transforms lactose in milk into lactic acid, giving cheese its distinct flavour and texture. This fermentation process also produces live cultures, including strains of Lactobacillus and Bifidobacterium, which are known for their probiotic benefits.
While the impact of dairy consumption on gut microbiota is still being studied, some research suggests that certain types of dairy products may affect the gut microbiome differently. A study by Jiao and colleagues found that increased milk consumption was associated with a rise in beneficial bacteria, while higher cheese intake was linked to lower levels of certain beneficial bacteria. However, it's important to note that the study had a small sample size and focused on colonic mucosal biopsies, which may not represent the entire gut environment.
Despite the mixed findings, some types of cheese, such as Swiss and Gouda, are recognized as good sources of probiotics. Blue cheeses, like Stilton, also offer a diverse range of bacteria. Additionally, fermented cheeses like Tunworth and Winslade are particularly rich in probiotics due to the fermentation process they undergo. Consuming these cheeses in moderation and as part of a diverse diet that includes plenty of plant-based sources of prebiotic fiber can contribute to a healthier gut microbiome.
In conclusion, while the impact of cheese on the gut is complex and influenced by various factors, fermented cheeses have the potential to positively impact gut health by providing beneficial probiotics and supporting a healthy balance of gut flora. Further research is needed to fully understand the intricate relationship between fermented cheese consumption and its effects on gut microbiota.

Blue cheeses provide a wide range of bacteria
While the impact of dairy products on gut microbiota is still being studied, some cheeses are considered to be a good source of probiotics. Blue cheese, in particular, provides a wide range of bacteria.
Blue cheese is formed by an impressive diversity of bacterial and fungal species. The overall quality of blue cheese is thought to result from the combined action of all members of the microbiota. The manufacture of most traditional blue cheeses from raw milk assures a high microbial diversity. The microbial analysis of blue cheeses has been addressed to the search for and selection of acidifying (LAB) and maturing (P. bacteria.
Blue-veined cheeses belong to a category of specialty cheeses that are distinguished from all others by their visual, taste, and aroma profiles. The distinct flavour of blue cheese comes from lipolysis (the breakdown of fat) and the metabolism of the blue mould, which breaks down fatty acids to form ketones and give the cheese a richer flavour and aroma.
The bacteria in blue cheese also contribute to its organoleptic properties, generating flavour compounds either directly through cellular metabolism or indirectly by releasing enzymes. For example, strains of Lc. lactis, subsp. lactis biovar diacetylactis, are frequently included in mesophilic starter cultures as they can catabolize citrate to carbon dioxide and the flavour compound diacetyl, which gives the cheese a distinct buttery flavour.
Blue cheeses are made with raw or pasteurised milk from cows, ewes, or goats, or a mixture of these. In France, most blue cheeses are made with cow's milk, except Roquefort, and in Spain and Greece, it is usual to add sheep's milk to cow's milk.
