According to a 2023 review, aged cheeses like blue cheese contain beneficial bacteria that could promote a balanced gut microbiome. This raises the question: is blue cheese good for gut health? While not a traditional probiotic powerhouse like yogurt, its fermentation process introduces a variety of microorganisms and bioactive compounds that may offer digestive benefits.

While medical penicillin originates from certain fungi, the specific strains of Penicillium used to create blue cheese do not produce the drug, according to experts. This fact complicates the popular belief that blue cheese is antibacterial, but scientific research reveals more fascinating truths about its properties.

Despite a common misconception, the mold used to produce blue cheese is not the same strain used to make the antibiotic penicillin. This means that blue cheese dressing does not contain the antibiotic penicillin, though the cheese itself is made with a different, food-safe mold. The confusion arises from both substances belonging to the same genus of fungi, *Penicillium*.

In 1928, Alexander Fleming discovered the antibiotic penicillin from a species of the Penicillium mold, but does blue cheese have antibiotic properties? The distinct, tangy flavor and blue-green veins of cheeses like Roquefort and Stilton are also due to a specific type of *Penicillium* mold, which can produce compounds with antibacterial and antifungal qualities.

Blue cheese has been enjoyed for centuries, with archaeological evidence suggesting that a form of blue cheese and beer was consumed in Iron Age Europe. This rich history raises the question: does blue cheese help your gut health, and what does modern science say about the microbial power within this distinctively veined delicacy?

According to scientific studies, salt is an essential ingredient in cheese production, contributing to its flavor, texture, and safety. The unmistakable pungency and strong flavor profile of blue cheese often comes with a distinct, sharp saltiness. So, why is blue cheese so salty? This is a result of salt's multiple critical roles in the cheesemaking process, including inhibiting unwanted bacteria and creating the perfect environment for the signature blue mold to flourish.

According to the USDA, the Penicillium mold used in making cheeses like Brie and Roquefort is safe and cultivated under controlled conditions. But is Penicillium healthy to eat in general? The answer is complex, as most molds found on spoiled food are toxic and should never be consumed.

According to a systematic review published in the *Journal of the American College of Nutrition*, fermented dairy products often have a neutral to beneficial effect on inflammation, which directly challenges the common assumption that all dairy promotes inflammation. This raises the question: is blue cheese an inflammatory food or could it be beneficial?

According to a 2025 study, increased cheese consumption is negatively associated with the risk of Non-Alcoholic Fatty Liver Disease (NAFLD). This surprising finding, along with the potential probiotic content from the Penicillium mold, prompts the question: is blue cheese good for your stomach and liver?

The blue veins in cheese are caused by molds from the *Penicillium* genus, the same genus that produced the first modern antibiotic, penicillin. This has led to the persistent question: is eating blue cheese like taking antibiotics? The short answer is no, and understanding why involves delving into the distinct worlds of cheesemaking and pharmaceutical science.
