Cheddar cheese is a good carrier of probiotics due to its higher pH, moderate acidity, and high fat content
Cheddar cheese is an excellent carrier of probiotics due to its higher pH, moderate acidity, and high fat content. Probiotics are live bacteria and yeasts that are good for digestive health. They are often called "good" or "helpful" bacteria because they support the gastrointestinal tract, prevent inflammation, boost immunity, reduce stress, improve mood, and alleviate conditions like allergies and diarrhea.
Cheese, in general, provides a more favourable environment for probiotics than other cultured dairy products like yogurt. This is because cheese has a moderate pH (4.8–5.6), lower titratable acidity, higher buffering capacity, greater fat content, low oxygen tension, and more appropriate storage conditions for probiotic viability and activity. The denser matrix and greater solid concentration in cheese also provide additional protection to probiotics during gastrointestinal passage.
Cheddar cheese, in particular, has been evaluated as a food carrier for the delivery of probiotic microorganisms, and mature raw cheddar cheese compares very favourably with fresh yogurt in this regard. Cheddar cheese has a higher pH than traditional probiotic foods like yogurts and fermented milk, providing a more stable environment for the long-term survival of probiotics. The matrix of Cheddar cheese and its relatively high-fat content also offer protection to probiotic bacteria as they pass through the gastrointestinal tract.
However, for Cheddar cheese to be an effective probiotic carrier, the microorganisms must be able to survive the relatively long ripening time of at least 6 months and/or grow during this period. During the ripening process, various non-pathogenic bacteria, including Lactobacillus and Bifidobacterium spp., proliferate in the maturing cheese. Studies have shown that probiotic Lactobacillus paracasei species are particularly suitable for Cheddar cheese applications, as they grow to high numbers and remain stable even after 8 months of ripening without affecting the cheese's composition or flavour.

Probiotics are good bacteria that promote gut health and prevent ailments like IBS
Probiotics are live microorganisms that are good for your health, especially your digestive system. They are often referred to as "good" or "helpful" bacteria because they promote gut health and prevent ailments like IBS. Probiotics are most effective in natural foods, and cheese is an excellent carrier for them due to its low acidity and high fat content, which preserve and nurture the bacteria as they move through the digestive system.
Cheddar cheese, in particular, has been evaluated as a food carrier for the delivery of probiotic microorganisms, and mature raw cheddar cheese has been found to compare favourably with fresh yogurt in terms of probiotic content. In fact, studies have shown that probiotic bacteria can survive in cheddar cheese and even modify populations of other lactic acid bacteria. This makes cheddar a promising vehicle for delivering probiotic benefits.
To ensure you're getting the probiotic benefits from cheddar cheese, it's best to buy raw and unpasteurized varieties. Raw cheese, made from unpasteurized milk, retains the natural bacteria from the environment and milk, which stay alive during fermentation. When consumed, these live bacteria are introduced into the body, promoting health and helping to maintain a balanced gut.
Additionally, cheddar cheese has a higher pH than traditional probiotic foods like yogurt and fermented milk, providing a more stable environment for the long-term survival of probiotic organisms. The matrix of the cheese and its relatively high fat content also offer protection to the probiotic bacteria as they pass through the gastrointestinal tract. However, it's important to consider the long ripening time of cheddar cheese, typically at least 6 months, and ensure that the microorganisms can survive or grow during this period.
Overall, cheddar cheese is a promising source of probiotics, offering a stable and protective environment for these beneficial bacteria. By consuming raw and unpasteurized cheddar cheese, individuals can introduce live probiotics into their digestive system, promoting gut health and preventing ailments like IBS.

Probiotics are added to foods like cheese for human health benefits
Probiotics are live bacteria and yeasts that are good for human health, especially digestive health. They are often referred to as "good" or "helpful" bacteria because they support the gastrointestinal (GI) tract, prevent inflammation, boost immunity, reduce stress, improve mood, and alleviate conditions ranging from allergies to diarrhea. Probiotics are added to foods like cheese to enhance their health benefits.
Cheese is a versatile food product that is appealing to many palates and suitable for all age groups. It is also an excellent carrier for probiotics due to its low acidity and high fat content, which preserve and nurture the bacteria as they move through the digestive system. The matrix of the cheese and its relatively high fat content may offer protection to probiotic bacteria during their passage through the gastrointestinal tract.
Cheddar cheese, in particular, has been evaluated as a food carrier for the delivery of probiotic microorganisms, and it has been found to compare very favorably with fresh yogurt. Mature raw cheddar cheese has a higher pH than traditional probiotic foods like yogurt and fermented milk, providing a more stable environment for the long-term survival of probiotics. Additionally, during the ripening period, a number of nonpathogenic bacteria, including Lactobacilli and Pediococci, proliferate in the maturing cheese, further enhancing its probiotic potential.
To ensure the probiotic effect, cultures must maintain their viability in food products through to the time of consumption, which for Cheddar cheese can be many months after manufacture. Several studies have been conducted to evaluate the performance of Lactobacillus strains, including L. salivarius and L. paracasei, when employed as adjuncts in Cheddar cheese. These strains have been shown to be acid and bile tolerant, adherent to human epithelial cells, nonpathogenic, and with desirable antibiogram profiles. The results demonstrate that the probiotic L. paracasei species are particularly suitable for Cheddar cheese applications, as they grow to high numbers and remain stable even after 8 months of ripening without affecting the cheese's composition or flavor.

Cheddar cheese with added Lactobacillus paracasei strains can be developed as a probiotic cheese
Probiotics are live bacteria and yeasts that are good for health, especially the digestive system. Eating certain foods, such as fermented foods, can help the gut maintain a healthy balance of bacteria. Probiotics have been shown to help with serious gut ailments like IBS and leaky gut syndrome, and they have many everyday benefits, such as supporting the gastrointestinal (GI) tract, preventing inflammation, boosting immunity, reducing stress, improving mood, and alleviating allergies and diarrhea.
Cheeses are excellent carriers for probiotics—their low acidity and high fat preserve and nurture the bacteria as they move through the digestive system. Cheeses that are rich in probiotics are either aged or made from raw, unpasteurized milk. Cheddar cheese, in particular, has been evaluated as a food carrier for the delivery of probiotic microorganisms, and it was found that mature raw cheddar cheese compares very favorably with fresh yogurt.
Lactobacillus paracasei is one of the species of lactic acid bacteria that is able to adapt to different environments. This is why L. paracasei is found naturally in both the human and animal gut and is used as a starter culture in the food industry, commonly in dairy products. It is also a species that has received GRAS (generally recognized as safe) status and is used in probiotic supplements.
In a study, cheddar cheese was manufactured with either Lactobacillus salivarius NFBC 310, NFBC 321, or NFBC 348 or L. paracasei NFBC 338 or NFBC 364 as the dairy starter adjunct. These five strains had been previously isolated from the human small intestine and have been characterized for their probiotic potential. It was found that both L. paracasei strains grew and sustained high viability in cheese during ripening, while each of the L. salivarius species declined over the ripening period. These data demonstrate that Cheddar cheese with added Lactobacillus paracasei strains can be developed as a probiotic cheese, effectively delivering probiotic organisms to the consumer.

Raw, unpasteurized cheeses are a good source of probiotics
Probiotics are live bacteria and yeasts that are good for digestive health and can be found in some types of cheese. These good bacteria can help keep the gut healthy and maintain a balance between helpful and harmful bacteria. Eating foods that contain probiotics can help restore this natural balance and foster the growth of good bacteria in the gut.
Cheeses that are rich in probiotics are either aged or made from raw, unpasteurized milk. The longer a cheddar cheese is aged, the more complex its flavour becomes and the higher the concentration of good bacteria it contains. However, it is important to note that raw, unpasteurized cheeses made from cow or goat's milk are the best sources of probiotics. These cheeses are typically found in European varieties, as they adhere to stricter production standards than American cheesemakers when creating probiotic-rich options.
When purchasing cheese, look for labels that indicate the cheese is made from raw (unpasteurized) milk and sourced from organic, grass-fed cows. Terms like "raw", "unpasteurized", or "non-thermal" on the packaging indicate that the cheese is a good source of probiotics. Soft-aged cheeses like Brie or Camembert generally have higher probiotic content than harder cheeses like Parmesan or Cheddar.
Some common probiotic cheeses include cheddar, feta, Gouda, provolone, Edam, brick, caciocavallo, Emmental, and Gruyere. These cheeses offer unique benefits, including providing probiotics and making it easier for the body to absorb nutrients. However, it is important to consume cheese in moderation, as it tends to be high in calories, saturated fat, and sodium.
