What is Lactose Intolerance?
Before diving into the specifics of processed cheese, it's important to understand what lactose intolerance is. It is a common digestive issue that occurs when the body does not produce enough of the enzyme lactase. This enzyme is responsible for breaking down lactose, the sugar found in milk and other dairy products. Without enough lactase, undigested lactose travels to the colon, where it is fermented by bacteria, leading to symptoms such as bloating, gas, cramps, and diarrhea.
It is important to differentiate between lactose intolerance and a milk allergy. A milk allergy is a more severe immune system reaction to milk protein, not sugar, and can cause a wide range of symptoms, including hives and breathing difficulties. For those with a milk allergy, all dairy must be strictly avoided. For those with lactose intolerance, many can tolerate small amounts of lactose, and low-lactose products are often manageable.
The Lactose Content of Kraft American Cheese
When it comes to Kraft American cheese, the answer to whether it contains lactose is a clear yes. Both Kraft Singles and Kraft Deli Deluxe American cheese contain milk-based ingredients that include lactose. The confusion often stems from the misconception that all processed cheeses are low in lactose like some aged natural cheeses.
Kraft Singles
Analysis of the ingredient list for Kraft Singles American slices shows multiple milk-derived ingredients, including:
- Cheddar cheese (made from cultured milk)
- Skim milk
- Milkfat
- Milk
- Milk protein concentrate
- Whey
While some of the lactose is broken down during the fermentation process of the cheddar cheese, other ingredients like whey and milk protein concentrate are added back in, ensuring the presence of lactose. Food ingredient analysis apps like Spoonful also confirm that Kraft Singles are not lactose-free and contain multiple lactose-based ingredients.
Kraft Deli Deluxe
Kraft Deli Deluxe slices also contain dairy and are not lactose-free. According to dietary analysis platforms, Deli Deluxe contains lactose-containing ingredients, confirming it is not a suitable option for those strictly avoiding lactose. The ingredients show a similar profile of processed cheese, with milk components present in the final product.
Why Processed Cheese Differs from Natural Aged Cheese
The key difference lies in the manufacturing process. The aging of natural cheese, like cheddar or Swiss, is what breaks down the lactose. During cheesemaking, milk is separated into curds and whey, with most of the lactose remaining in the whey. For hard, aged cheeses, the whey is drained extensively, and any remaining lactose in the curds is consumed by beneficial bacteria over time, a process called fermentation. The longer a cheese is aged, the lower its lactose content becomes.
Processed American cheese, however, is made by blending and melting natural cheeses with other dairy and non-dairy ingredients, such as emulsifiers and preservatives. Some of the added ingredients, like milk solids and whey, reintroduce or increase the lactose content, unlike the reduction seen in aged natural cheeses.
Comparing Lactose Content: Processed vs. Natural Cheeses
To better understand the differences, here is a comparison of the typical lactose levels in common cheese types.
| Cheese Type | Processing | Typical Lactose Content (per 1.5 oz serving) | Suitable for Lactose Intolerance? |
|---|---|---|---|
| Kraft American Singles | Processed | Moderate, contains milk and whey | Not suitable for moderate to severe intolerance |
| Kraft Deli Deluxe | Processed | Moderate, contains lactose ingredients | Not suitable for moderate to severe intolerance |
| Aged Cheddar | Natural, Aged > 1 year | < 1 gram | Often tolerated by those with intolerance |
| Swiss Cheese | Natural, Aged | < 1 gram | Often tolerated by those with intolerance |
| Parmesan | Natural, Aged > 1 year | < 1 gram | Often tolerated by those with intolerance |
| Ricotta | Natural, Fresh | 1–5 grams | Higher lactose, may cause symptoms |
| Cottage Cheese | Natural, Fresh | 1–5 grams | Higher lactose, may cause symptoms |
Finding Lactose-Free Alternatives
For those with lactose intolerance, there are plenty of options beyond processed American cheese that can fit into a healthy diet.
Low-Lactose Dairy Options:
- Aged Cheeses: Hard, aged cheeses like Parmesan, Swiss, and aged Cheddar have very low to non-detectable levels of lactose and are generally well-tolerated.
- Greek Yogurt: The straining process used to make Greek yogurt removes much of the whey and lactose, making it easier to digest.
- Lactose-Free Dairy: Many brands offer lactose-free milk, yogurt, and other dairy products treated with the lactase enzyme to break down the sugar before consumption.
Dairy-Free Cheese Alternatives: For those who need to avoid dairy entirely, numerous plant-based cheese options are now available.
- Nut-Based Cheeses: Made from cashews, almonds, and other nuts, these often have a creamy texture and are naturally lactose-free.
- Soy-Based Cheeses: Products made from soy protein offer another non-dairy cheese alternative.
- Other Plant-Based Cheeses: Look for varieties made from ingredients like coconut oil, nutritional yeast, or potato starch for different textures and flavors.
Conclusion
In summary, Kraft American cheese slices are not lactose-free and contain milk-based ingredients. For individuals with lactose intolerance, understanding the distinction between processed and aged natural cheeses is key to managing symptoms effectively. While some aged cheeses are naturally very low in lactose, processed varieties like Kraft American slices can contain higher amounts that may trigger digestive discomfort. By exploring naturally low-lactose aged cheeses, lactose-free dairy products, or plant-based alternatives, those with sensitivities can continue to enjoy delicious, cheese-like flavors without the worry of unwelcome symptoms. Always check ingredient lists and choose products that align with your personal tolerance level and dietary needs.
