Understanding Histamine in Cheese
Histamine is a naturally occurring compound that can trigger a range of symptoms in individuals with histamine intolerance. In cheese, histamine levels are not static; they are directly influenced by the production and aging processes. The key factor is the conversion of the amino acid histidine into histamine by bacteria that produce the enzyme histidine decarboxylase. This process increases significantly with aging, meaning the fresher the cheese, the lower the histamine content.
Low-Histamine Cheeses: The Safest Choices
For those on a low-histamine diet, the best cheeses are those that are young, soft, and unaged. These include fresh dairy products that have undergone minimal fermentation. The fresher, the better.
Recommended Low-Histamine Cheeses:
- Mozzarella: Especially fresh mozzarella packed in liquid, this cheese is typically very low in histamine.
- Ricotta: A fresh, soft, and creamy cheese that is made from whey and is generally well-tolerated.
- Cream Cheese: Plain, un-fermented cream cheese is usually low in histamine, but it is important to check the label for additives and stabilizers.
- Cottage Cheese: This fresh cheese is noted as suitable for those with histamine sensitivities, as long as it is a plain, unflavored variety.
- Mascarpone: A rich, soft Italian cream cheese that is very low in histamine.
- Paneer: This fresh cheese is made by curdling milk with an acidic agent, not bacterial cultures, which keeps histamine levels low.
- Young Gouda: While aged Gouda is high in histamine, young Gouda is considered a safer, lower-histamine option.
High-Histamine Cheeses to Avoid
As a rule of thumb, the more aged, hard, and fermented a cheese is, the higher its histamine content will be. These cheeses should be avoided by individuals with histamine intolerance.
Cheeses with High Histamine Content:
- Aged Hard Cheeses: Parmesan, aged Cheddar, Romano, Swiss cheese, and aged Gouda are all high in histamine due to their long maturation periods.
- Blue Cheeses: Gorgonzola, Roquefort, and Stilton are aged with bacteria and mold, resulting in high levels of histamine.
- Molded Cheeses: Soft, molded-rind cheeses like Brie and Camembert contain significant histamine.
- Processed Cheese: Processed varieties can also contain high levels of histamine and additives that may be problematic.
Comparison Table of Cheese Histamine Levels
| Cheese Type | Typical Histamine Level | Reason for Histamine Level |
|---|---|---|
| Mozzarella | Low | Unaged, fresh cheese. |
| Ricotta | Low | Fresh cheese made from whey. |
| Cream Cheese | Low (plain) | Unfermented and unaged. |
| Cottage Cheese | Low (plain) | Fresh, unflavored curd cheese. |
| Aged Cheddar | High | Ripened and fermented over a long period. |
| Parmesan | High | Hard, mature cheese with long aging time. |
| Blue Cheese | High | Aged with mold and bacteria. |
| Brie/Camembert | High | Soft, molded-rind cheese. |
Factors Affecting Histamine Content
Several factors beyond just aging influence the histamine content of cheese:
Bacterial Starter Cultures
The specific strains of bacteria used in the cheesemaking process play a critical role. Some bacteria, like Lactobacillus buchnerii, are known histamine producers. The specific culture used can lead to high histamine even in a relatively young cheese if the process is not carefully controlled.
Storage Conditions
Temperature is a major factor, as histamine production continues after manufacturing. Studies show that cheeses stored at higher temperatures have a significantly higher histamine content than those kept consistently refrigerated. Always store cheese properly and follow expiration dates to minimize histamine buildup.
Manufacturing Process
Cheeses made from unpasteurized raw milk may carry a higher risk of containing histamine-producing bacteria. The fermentation process itself, even in fresh cheeses, can still generate some histamine, though far less than in aged varieties.
Tips for Choosing and Consuming Low-Histamine Cheese
- Prioritize Freshness: Look for the freshest options available and consume them quickly. Avoid keeping leftovers for extended periods.
- Go Plain: Stick to plain, unflavored varieties. Added herbs, spices, or other ingredients could contain or trigger histamine.
- Read Labels: Check ingredient lists for additives, stabilizers, or thickeners that might cause issues. Stick with the simplest ingredient lists.
- Monitor Portions: Even low-histamine cheeses contain some histamine. Pay attention to your individual tolerance levels and consume in moderation.
- Consider Pasteurization: Opt for cheeses made from pasteurized milk, as they are considered a lower risk.

Conclusion
Finding a suitable cheese on a low-histamine diet requires focusing on fresh, unaged, and non-fermented options. The guiding principle is simple: the shorter the aging time and the fresher the product, the better the choice. By selecting cheeses like mozzarella, ricotta, cream cheese, and cottage cheese, and avoiding the aged, blue, and molded varieties, individuals with histamine intolerance can still enjoy a range of delicious cheese-based meals and snacks safely. Always pay attention to how your body reacts and prioritize the freshest ingredients to minimize your histamine intake.
