The Penicillin Myth: Blue Cheese as Medicine
One of the most persistent myths surrounding blue cheese is its supposed ability to cure illnesses, a belief often stemming from its moldy appearance and the history of penicillin. The iconic antibiotic, which has saved millions of lives, was discovered by Alexander Fleming from a species of Penicillium mold. This link, however, is a classic case of mistaken identity.
Blue Cheese Mold vs. Medical Penicillin
The mold used to produce blue cheese, primarily Penicillium roqueforti, is a specific, food-safe strain. It is entirely different from the strain originally used to create medicinal penicillin, Penicillium notatum (later replaced by Penicillium chrysogenum). Pharmaceutical-grade penicillin is a highly concentrated and purified extract, manufactured under sterile, controlled conditions. The trace amounts of mold-related compounds in blue cheese have no therapeutic effect against bacterial infections comparable to an antibiotic drug.
The True Immunological Benefits of Blue Cheese
While it won't cure a cold or infection, blue cheese can play a supportive role in a healthy diet that benefits your immune system. Its health-promoting properties are not magic but rather the result of its rich nutritional profile and probiotic content.
The Probiotic Power of Fermented Cheese
As a fermented food, blue cheese contains beneficial bacteria, also known as probiotics, that contribute to a healthy gut microbiome. The health of your gut is intrinsically linked to the health of your immune system, as approximately 70% of the body's immune cells reside in the gut. A balanced gut can help support a more robust and effective immune response.
- Promotes Digestive Health: The probiotics can aid in digestion and help maintain a healthy balance of microorganisms in the gut.
- Supports Immune Function: Research, particularly on the elderly, suggests that probiotic consumption via cheese can enhance immune responses.
A Nutritious Immune-Supporting Profile
Beyond probiotics, blue cheese is packed with essential vitamins and minerals that are crucial for maintaining a healthy immune system.
- Zinc: A single ounce serving provides a good source of zinc, a mineral vital for immune cell function and wound healing.
- Vitamins: It contains Vitamin A and Vitamin D, both of which are important for regulating the immune system.
- Calcium and Phosphorus: These minerals are known for their role in bone health, but they also contribute to various cellular functions that support overall well-being.
Anti-Inflammatory Effects and Antioxidants
Studies have also explored the anti-inflammatory properties of blue cheese. Compounds produced during the fermentation process, such as peptides and the polyamine spermidine, may have anti-inflammatory and antioxidant effects. Chronic inflammation is linked to numerous health issues, so consuming foods with potential anti-inflammatory properties is beneficial for long-term health.
Potential Risks and Considerations
While blue cheese offers benefits, it is important to consume it in moderation due to its high sodium and fat content. There are also specific risks for certain individuals.
High Sodium and Fat Content
Because blue cheese is relatively high in sodium, individuals with hypertension or those on low-sodium diets should be mindful of their intake. Its fat content, particularly saturated fat, should also be considered as part of a balanced diet.
Risks for Vulnerable Groups: Listeria
Certain groups, including pregnant women, infants, the elderly, and those with compromised immune systems, are advised to be cautious or avoid soft, mold-ripened cheeses due to the potential risk of Listeria monocytogenes contamination. While semi-soft cheeses don't typically support Listeria growth, some blue cheeses may pose a risk. Thoroughly researched guidelines from food safety authorities, such as the Food Standards Agency, exist to help protect these individuals.
Allergies and Migraines
Individuals with mold allergies should avoid blue cheese, as it contains mold cultures that could trigger a reaction. Furthermore, some people report that aged cheeses, including blue cheese, can trigger migraines or headaches, though the reason is not fully understood.
Blue Cheese Mold vs. Medicinal Mold: A Comparison
| Feature | Blue Cheese Mold (Penicillium roqueforti) | Medicinal Penicillin Mold (Penicillium notatum) |
|---|---|---|
| Purpose | Flavor, aroma, and texture development in food. | Production of the antibiotic penicillin to treat infections. |
| Effect | Food-safe, offers probiotic and antioxidant benefits. | Acts as a potent antibacterial agent against certain bacteria. |
| Application | Ingested as a part of a food item. | Purified and administered as a drug (injection or oral). |
| Potency | Ineffective for treating bacterial infections. | Highly potent and effective against target pathogens. |
| Safety | Generally safe for most people, but caution advised for vulnerable groups due to other risks (e.g., Listeria). | Not present in finished pharmaceutical product, but the drug can cause allergies. |
Conclusion
In summary, the answer to the question "Does blue cheese help with illness?" is a complex one. While it is certainly not a medical treatment or substitute for antibiotics like penicillin, it does contain properties that can support a healthy immune system. The presence of beneficial probiotics, essential vitamins like zinc and D, and anti-inflammatory compounds makes it a valuable addition to a balanced diet. However, this is not a justification for overconsumption. Moderate intake is key, and vulnerable individuals should be aware of potential risks like Listeria contamination. The myth that blue cheese is a cure-all is a romanticized oversimplification that ignores the nuanced science behind both cheesemaking and medicine. For serious infections, only professionally prescribed antibiotics, not a culinary delight, can provide effective treatment.

How to Incorporate Blue Cheese into a Healthy Diet
To enjoy the potential benefits of blue cheese, consider adding it to your meals in sensible, balanced ways.
- Salads: Crumble blue cheese over a fresh green salad with nuts and fruit for a nutrient-dense meal.
- Sauces: Use a small amount to create a flavorful sauce for vegetables or lean protein.
- Appetizers: Pair it with fiber-rich crackers or vegetables for a healthy snack.
- Portion Control: Due to its high sodium content, use it sparingly as a flavor enhancer rather than the main ingredient.
By treating blue cheese as a flavorful, nutritious supplement rather than a medicinal cure, you can reap its health-supporting qualities without falling for the misconception that it can defeat illness on its own.
