Is There Gluten in Kraft Cheese Slices? A Detailed Guide

November 9, 2025 •

4 min read

According to the Celiac Disease Foundation, more than 3 million people in the United States have celiac disease, making the question, 'Is there gluten in Kraft cheese slices?' a vital dietary concern. Most traditional cheeses are naturally gluten-free, but processed cheese products, like those from Kraft, often contain additional ingredients that require careful scrutiny. While many Kraft Singles varieties are made without gluten-containing ingredients, others, including some 'cheese products,' may contain additives that require a closer look.

Quick Summary

An analysis of Kraft cheese slices reveals that many varieties are manufactured without gluten ingredients. However, labels can change, and some processed cheese products differ, so reviewing the ingredient list is always necessary for those with gluten sensitivities or celiac disease. Cross-contamination is also a risk for susceptible individuals.

Key Points

Ingredient check: Most Kraft Singles are made without gluten ingredients, but the ingredient list can vary by product and region.
Modified Food Starch: In the US, this is typically a gluten-free additive made from corn or potato, but always check the label for wheat disclosure.
Cross-Contamination Risk: Due to shared manufacturing facilities, there is a risk of cross-contamination for individuals with severe gluten sensitivities or celiac disease.
Labeling Policy: Kraft's official policy is to list all sources of gluten-containing ingredients, but they do not label all products 'Gluten-Free'.
Natural Cheese Alternative: For maximum safety, opt for simple block cheeses or certified gluten-free brands, as they have a lower risk of cross-contamination.
In-store vs. Deli: Be mindful of cheese sliced at the deli counter, as cross-contamination from other products on shared equipment is a possibility.

What is in Kraft cheese slices?

Kraft cheese slices, including the popular Kraft Singles, are technically processed cheese products, not natural cheese. This distinction is important for understanding their ingredients. While the core components of real cheese—milk, cheese culture, salt, and enzymes—are gluten-free, processed versions can contain a host of additional ingredients.

For example, the ingredient list for Kraft Singles American Slices often includes:

Cheddar Cheese (Cultured Milk, Salt, Enzymes)
Skim Milk
Milkfat
Milk Protein Concentrate
Whey
Calcium Phosphate
Sodium Phosphate
Modified Food Starch
Salt
Lactic Acid
Sorbic Acid
Annatto (color)
Cheese Culture
Enzymes

As seen in this list, a primary concern is the 'Modified Food Starch'. For consumers in the U.S., this ingredient is generally derived from corn, potatoes, or waxy maize, all of which are gluten-free. By law, if a wheat-based starch is used, it must be explicitly labeled as 'modified wheat starch'. Kraft's labeling policy is to list all sources of gluten-containing ingredients, making it easier for consumers to identify a potential problem.

Potential cross-contamination risks

Even if the ingredients are gluten-free, cross-contamination is a significant concern for those with celiac disease or severe gluten sensitivities. Kraft manufactures a wide range of products, and their facilities are not exclusively dedicated to gluten-free production.

Sources of cross-contamination can include:

Shared machinery: Production lines may be used for both gluten-free and gluten-containing products, despite extensive cleaning protocols.
Flavorings and colorings: While Kraft labels for gluten, they sometimes source flavorings or colors from third-party suppliers who may not list every potential source of gluten.
Product variations: Ingredient lists can vary by region and product type. Always check the specific packaging for the most accurate information.

For most people with a gluten sensitivity, the risk from Kraft singles may be low due to strict internal policies and labeling. However, for those with severe celiac disease, consulting the company or a healthcare provider is prudent.

Comparison: Kraft Slices vs. Other Gluten-Free Cheeses


Feature	Kraft Singles	Certified Gluten-Free Brands (e.g., Tillamook, Cabot)	Natural Cheeses (e.g., Cheddar, Mozzarella)
Gluten-Containing Ingredients	No gluten ingredients are typically used, but ingredient lists can vary by product and region.	Explicitly made without gluten ingredients.	No gluten ingredients are used by nature.
Cross-Contamination Risk	Present, as products are made in facilities that also process gluten-containing foods.	Minimal to non-existent, depending on certification and facility practices.	Very low, especially for block cheeses. Risk increases for pre-shredded varieties.
Processing	Highly processed cheese product with emulsifiers and preservatives.	Varies by brand. Can be processed or unprocessed, but with strict gluten-free protocols.	Minimally processed, with a focus on simple ingredients.
Labeling	Relies on ingredient labeling and company policy. May not be explicitly marked 'Gluten-Free'.	Often features a 'Certified Gluten-Free' logo for assurance.	Not typically labeled as 'Gluten-Free' unless specifically requested by manufacturer.
Best For	Individuals without celiac disease or high sensitivity who want a convenient processed slice.	Individuals with celiac disease or high sensitivity who require certified products.	Anyone seeking the most natural, least processed cheese option.

Natural cheese is a safer bet

For those with celiac disease or a high level of gluten sensitivity, opting for natural cheeses is a safer choice. Block cheeses, in particular, are less likely to be contaminated because they are not processed with other additives or starches. The risk with pre-shredded cheese is that anti-caking agents, like starches, are sometimes used. While companies like Kraft and others use corn or potato starch, reading the label is always the best practice.

Making your own cheese at home

For complete control over ingredients and production, making cheese at home is the ultimate gluten-free option. Recipes for simple cheeses like ricotta, cottage cheese, or even more complex hard cheeses are widely available online. This eliminates all risk of cross-contamination and allows for ingredient customization.

Conclusion

While many varieties of Kraft cheese slices do not contain gluten ingredients and are considered safe for most people on a gluten-free diet, a definitive 'yes' requires careful scrutiny. The presence of ingredients like modified food starch and the possibility of cross-contamination in shared facilities mean that relying solely on brand reputation is not enough for individuals with celiac disease. The safest practice is always to read the ingredient label on every single package. For the most risk-averse, certified gluten-free brands or simple block cheeses are a better alternative, guaranteeing a safe, gluten-free experience.

By staying informed and vigilant about product labels and manufacturing practices, consumers can confidently navigate their dietary needs while still enjoying their food. If in doubt, purchasing a product explicitly labeled 'Certified Gluten-Free' provides the greatest assurance.
