Probiotics are beneficial bacteria purported to regulate the digestive tract, prevent and treat urinary tract and vaginal yeast infections, improve recovery of intestinal infections, and possibly reduce the length and severity of the common cold and flu. Although eating probiotic food such as blue cheese isn’t necessary to maintain a healthy diet, you may experience some health benefits by doing so. The majority of dairy products, particularly yogurt and cheese, contains a certain amount of probiotic bacteria. In some cases, however, the probiotic content depends on the manufacturer.

Lactic Acid Bacteria
Lactic acid is one of the most well-known probiotics. It is usually the starter culture for items like yogurt and cheese. According to a September 2006 article published in “Current Issues in Intestinal Microbiology,” lactic acid bacteria improved symptoms of allergic diseases and helped to improve immune response. Although hundreds of lactic acid probiotics exist, the most beneficial appear to be the lactobacillus group, also present in blue cheese. For example, a June 2010 article published in “FEMS Immunology and Medical Microbiology” found that Lactobacillus rhamnosus and Lactobacillus acidophilus effectively enhanced the immune system of elderly subjects. A June 2004 article published in the “Journal of Physiology and Biochemistry” found that Lactobacillus casei in fermented milk, such as cheese, improve immune defense response in health, middle-aged patients.
Bifidobacteria are also well-recognized probiotics appearing in the majority of dairy products, including blue cheese. Lactic-acid bacteria and bifidobacteria typically work in conjunction with one another. For example, a March 2001 study published in “Food Technology and Biotechnology” says that these two bacterial types helped to alleviate lactose intolerance, prevent and reduce the symptoms of diarrhea, improve the immune system and lower cholesterol levels.
The characteristic blue veins present in blue cheese are from the fungus Penicillium roqueforti. This fungal strain is also responsible for the pungent smell blue cheeses tend to have. Blue cheese also contains yeast, a type of fungus, particularly Debaryomyces hansenii, Yarrowia lipolytica, Kluyveromyces marxianus, Kluyveromyces lactis and Candida spp. These fungi contribute significantly to the taste of blue cheese are emerge somewhat symbiotically with lactic acid bacteria, according to a November 2003 article published in “Food Technology and Biotechnology.” Although some fungi do have probiotic qualities, the bacterial strains in blue cheese are far more beneficial.
Bifidobacteria and lactic acid bacteria are always present in blue cheese, although certain strains may not be included depending on the manufacturer. Since the efficacy of these microorganisms still requires further research, you should always consult your physician before making any dietary changes. This is particularly important if you have any intestinal conditions. Although these bacterial strains are generally already present in your intestinal tract, they exist in a delicate balance. Consuming a varied diet is ideal for your health.
