The role of fermentation and aging in cheese production
Cheese production is an ancient craft involving the fermentation of milk using bacteria and enzymes. This process transforms milk into a complex food with unique flavors, textures, and aromas. However, this same process is responsible for the formation of biogenic amines, including histamine. Histamine is created when bacteria and other microorganisms break down the amino acid histidine, a natural component of milk protein.
The level of histamine in a cheese is directly related to its production process. Key factors include the types of bacterial starter cultures used, the duration of maturation or aging, and storage conditions such as temperature. Longer ripening times, as seen in hard, aged cheeses, allow more opportunity for histamine-producing bacteria to convert histidine, leading to higher histamine content. Conversely, cheeses that are not aged or undergo minimal fermentation will have significantly lower histamine levels.
Histamine intolerance and its impact
Histamine is a chemical signaling molecule that plays a role in the body's immune response, regulating various functions, including blood vessel dilation, smooth muscle contraction, and stomach acid secretion. When the body's histamine level is balanced, it's a vital part of healthy function. However, problems arise for individuals who lack sufficient levels of the enzyme diamine oxidase (DAO), which is responsible for breaking down excess histamine in the gut.
For these individuals, ingesting high-histamine foods can lead to an accumulation of histamine in the body, triggering a variety of allergy-like symptoms. This condition is known as histamine intolerance. The symptoms can be wide-ranging and may mimic those of an allergic reaction, though it is not a true allergy.
Common symptoms of histamine intolerance include:
- Headaches or migraines
- Skin issues such as rashes, hives, and flushing
- Gastrointestinal problems, including nausea, bloating, and diarrhea
- Respiratory issues like a stuffy or runny nose, and wheezing
- Heart palpitations or rapid heartbeat
Navigating cheese on a low-histamine diet
Contrary to the idea that cheese could be an antihistamine, many varieties are problematic for those with histamine intolerance. Therefore, understanding which cheeses to include or avoid is essential for a balanced and symptom-free diet.
High-histamine cheeses to avoid
As a general rule, the more aged or fermented a cheese, the higher its potential histamine content. For individuals sensitive to histamine, it is often necessary to avoid the following types of cheese:
- Aged and hard cheeses: This includes well-matured varieties like parmesan, aged cheddar, Swiss cheese, and aged gouda.
- Blue cheeses: Cheeses ripened with mold, such as gorgonzola, roquefort, and stilton, are very high in histamine.
- Processed cheeses: Many processed cheeses contain additives and may be made with aged components that increase histamine levels.
- Soft ripened cheeses: Varieties like brie and camembert, which are ripened with bacteria or mold, should be avoided.
Low-histamine cheeses to consider
Fortunately, cheese lovers on a low-histamine diet still have options. Fresh, unripened cheeses tend to have much lower histamine levels and are often well-tolerated. These include:
- Mozzarella: A fresh, unripened cheese that is a good choice for those with histamine intolerance.
- Ricotta: Another unaged, low-histamine option.
- Cottage cheese: Fresh and unfermented cottage cheese is considered a low-histamine dairy product.
- Cream cheese: Plain, unfermented cream cheese is often a safe option.
- Mascarpone: This fresh Italian cheese is also generally low in histamine.
Comparing cheese types for histamine sensitivity
| Cheese Type | Ripening Process | Histamine Level | Best For Low-Histamine Diet? |
|---|---|---|---|
| Parmesan | Hard, long-aged | High | No, avoid |
| Gouda (Aged) | Aged and ripened | High | No, avoid |
| Blue Cheese | Ripened with mold | High | No, avoid |
| Cheddar (Aged) | Matured | High | No, avoid |
| Mozzarella | Fresh, unripened | Low | Yes, generally safe |
| Ricotta | Fresh, unripened | Low | Yes, generally safe |
| Cream Cheese | Fresh, unfermented | Low | Yes, generally safe |
| Cottage Cheese | Fresh, unfermented | Low | Yes, generally safe |
Natural foods with antihistamine properties
While no cheese serves as an antihistamine, certain foods contain nutrients that can support the body's natural processes for managing histamine or have anti-inflammatory effects. These can be beneficial additions to a balanced nutrition plan for those with histamine intolerance. Some of these include:
- Vitamin C: Found in red bell peppers, broccoli, and citrus fruits (though citrus can be a histamine releaser for some). Vitamin C is a powerful antioxidant and is a necessary cofactor for the DAO enzyme.
- Quercetin: A flavonoid with antihistamine properties found in onions, apples, and berries.
- Bromelain: An enzyme found in pineapple that may help reduce sinus inflammation related to allergies.
- Probiotics: Some probiotics, like certain strains of Bifidobacterium and Lactobacillus, may help regulate immune responses and improve gut health, which can be linked to better histamine management.
- Nettles: Stinging nettle is an herb that has been used traditionally to relieve allergy symptoms.
Conclusion: Making informed dietary choices
It's a common misconception that cheese, or dairy in general, is an antihistamine. The reality is that the histamine content in cheese depends heavily on its level of fermentation and aging. Those with histamine intolerance must carefully consider their choices to avoid triggering unwanted symptoms. By opting for fresh, unripened cheese and incorporating other foods with natural antihistamine properties, it's possible to maintain a varied and enjoyable diet while managing symptoms effectively. Always consult with a healthcare professional or registered dietitian before making significant changes to your diet, especially if you suspect you have histamine intolerance or other sensitivities.

Making sense of your diet and histamine intolerance
Understanding which cheeses are low or high in histamine is crucial for managing symptoms associated with histamine intolerance, a condition caused by a lack of the enzyme that breaks down histamine. Choosing fresh, unripened varieties like mozzarella or ricotta can help prevent adverse reactions, while aged and fermented cheeses should be avoided. A personalized approach, possibly guided by a professional, is key to developing a sustainable, low-histamine nutrition diet. Freshness is also a vital factor, as histamine levels increase over time even in typically low-histamine foods.
