The Hidden Gluten in Processed Cheeses
For individuals with celiac disease, the dairy aisle can present unexpected challenges. While plain, hard cheeses like cheddar and parmesan are typically safe, it's the processed and packaged products that demand caution. Gluten is often used as a stabilizer, thickener, or anti-caking agent during manufacturing to improve a product's texture or extend its shelf life. Therefore, products that are highly processed should always be considered high-risk unless certified gluten-free.
Types of Processed Cheeses to Question
- American Cheese: The individually wrapped slices or blocks often contain modified food starch or other gluten-containing stabilizers.
- Cheese Spreads and Sauces: Jars, cans, or sprayable cheese products are prime candidates for hidden gluten, used to achieve a creamy consistency.
- Flavored Cheeses: Products with added ingredients like spices, herbs, or crackers should be avoided unless explicitly labeled gluten-free. Beer cheese spreads are another high-risk item due to malt content.
- Powdered Cheese: Found in macaroni and cheese mixes and other convenience products, cheese powders can contain gluten-based ingredients.
- Low-Fat or Fat-Free Cheeses: Manufacturers may use gluten-containing fillers to compensate for the removed fat and maintain a desirable texture.
The Special Case of Blue Cheese
The safety of blue cheese has historically been a point of confusion for the celiac community. The mold cultures used to create the signature veins in blue cheese are sometimes grown on gluten-containing media, such as wheat or rye bread. However, modern testing and production methods have largely mitigated this risk. The Canadian Celiac Association and other organizations have found that the residual gluten in the final product is typically below the 20 ppm threshold considered safe for celiac consumption.
Despite this, vigilance is still advised. Some manufacturers may still use traditional, gluten-based cultures, so it is always wise to check the packaging and, when in doubt, choose a brand known to use gluten-free cultures. Trusted sources like Beyond Celiac and The Spruce Eats offer updated lists of confirmed gluten-free brands.
The Risk of Cross-Contamination
Cross-contamination is a significant concern for those with celiac disease, and the cheese counter is no exception. This risk can occur in several scenarios:
Deli Counter Best Practices
When purchasing cheese from a deli counter, it's crucial to take precautions. The same slicer or gloves might be used for gluten-containing products, such as deli meats coated in spices or sandwiches, before handling the cheese. To ensure safety, request that the employee use a clean slicer and fresh gloves before preparing your order.
At-Home Cross-Contamination
Be mindful of shared utensils and cutting boards at home. If a knife used to cut a gluten-containing bread is then used to slice a block of cheese, cross-contamination can occur. Using separate utensils and surfaces for gluten-free foods is a simple but effective strategy.
The Additive in Shredded Cheeses
Pre-shredded or grated cheese is a convenience product that often contains additives to prevent clumping. While many manufacturers use gluten-free starches like potato or corn starch, some may use wheat starch. For this reason, it is always safest to shred your own cheese from a solid block or purchase a certified gluten-free version. The ingredient label will clarify the type of anti-caking agent used.
Comparison of Risky and Safer Cheese Options
| Feature | Potentially Risky Cheeses | Generally Safe Cheeses | Precaution | Authoritative Source |
|---|---|---|---|---|
| Form | Processed slices, spreads, sauces, powders | Solid blocks, wedges, wheels | Always check ingredients, especially for stabilizers and flavors | Schär |
| Flavor | Flavored with spices, crackers, beer | Plain, unflavored varieties | Avoid products with added seasonings or mix-ins | Cello Cheese |
| Fat Content | Low-fat, fat-free options | Full-fat, natural cheeses | Low-fat versions may use gluten as a filler | Schär |
| Prep | Pre-shredded, grated | Solid blocks to be grated at home | Pre-shredded often contains anti-caking agents; check the type | Beyond Celiac |
| Type | Some blue cheeses, American cheese | Cheddar, Swiss, Parmesan, Feta, Goat Cheese, Mozzarella | Research the brand for blue cheese cultures; American is often processed | National Celiac Association |
Conclusion: Label Reading is Key
The most crucial takeaway for celiacs concerning cheese is that, while many varieties are naturally gluten-free, vigilance is required for all processed and packaged products. Read ingredient labels carefully, look for certified gluten-free products, and be aware of potential cross-contamination risks at delis and in shared kitchen spaces. By following these guidelines, you can safely enjoy cheese as part of a healthy, gluten-free lifestyle.

The Risks and Rewards of Navigating the Dairy Aisle
By being informed and cautious, celiac patients can continue to enjoy a wide variety of delicious, naturally gluten-free cheeses. Always opt for the least processed option, and when in doubt, stick to fresh, plain cheeses from reputable brands. Your health depends on it.
Final Recommendations
Ultimately, a celiac's best defense is to stick to simple, whole foods. When it comes to cheese, this means purchasing solid blocks of cheese and grating or slicing them at home. For processed items, look for a 'Certified Gluten-Free' logo, which indicates the product has been tested to meet strict gluten-free standards. This practice will prevent inadvertent exposure and ensure a safe and enjoyable dining experience.
