The USDA's Official Dairy Measurement
For nutritional tracking and dietary guidelines, the USDA provides specific equivalents for how different foods count towards your daily dairy intake. When it comes to processed cheese, the official standard is that a 2-ounce serving equals one cup from the dairy group. In contrast, a 1.5-ounce serving of natural cheese, like cheddar or mozzarella, is considered one dairy cup. This variance is a direct result of the differences in how each product is manufactured and what ingredients are included. The higher weight requirement for processed cheese accounts for the non-cheese ingredients blended into the final product.
Understanding What's in Processed Cheese
Processed cheese is created by mixing and heating natural cheese with a blend of other dairy and non-dairy ingredients. Additives provide a uniform texture, longer shelf life, and improved meltability.
Ingredients often include:
- Natural cheese (e.g., cheddar or colby)
- Emulsifying salts
- Water and sometimes milk or cream
- Nonfat milk solids or whey protein concentrates
- Coloring agents, flavorings, and preservatives
Ingredient formulation varies by product classification.
The Role of Emulsifying Salts
Emulsifying salts, such as sodium phosphate, are vital in processed cheese to prevent fat and protein separation during heating, ensuring a smooth, consistent texture as it melts.
Processed Cheese vs. Natural Cheese: A Content Comparison
The table highlights key differences between processed and natural cheese:
| Feature | Natural Cheese | Pasteurized Process Cheese Food | Pasteurized Prepared Cheese Product |
|---|---|---|---|
| Starting Point | Milk | At least 51% natural cheese | Less than 51% natural cheese |
| Key Process | Milk coagulation and aging | Heating and blending with additives | Heating and blending, more non-cheese ingredients |
| Additional Ingredients | Starter cultures, enzymes | Emulsifying salts, milk, whey | Emulsifying salts, water, oils |
| Dairy Content | Higher concentration | At least 51% cheese, plus additives | Can be significantly lower in dairy |
How FDA Standards Define Dairy Content
FDA standards classify dairy products, influencing the composition of processed cheese.
- Pasteurized Process American Cheese: Primarily natural cheese with emulsifying agents and other additives.
- Pasteurized Process American Cheese Food: Minimum 51% natural cheese; allows for added dairy like cream or whey.
- Pasteurized Prepared Cheese Product: Unregulated term; can have less than minimum cheese content and include more non-dairy items or oils. This category generally contains the least dairy.
The Production Process: From Curds to Slices
Manufacturing involves grinding natural cheese, mixing it with ingredients, heating it, and then forming it into shapes. This creates a smooth product with consistency and shelf-stability.
Nutritional Considerations Beyond Dairy Cups
While contributing to dairy intake, processed cheese often has higher sodium and may include additives. Checking labels for specific nutritional information is recommended.

Conclusion
Two ounces of processed cheese is counted as one cup of dairy by the USDA. However, the composition varies by product type, with different categories containing varying amounts of natural cheese and additional ingredients. Understanding these differences helps in making informed dietary choices.
Frequently Asked Questions
Q: Does all processed cheese contain the same amount of dairy? A: No, the natural cheese content varies. “Cheese food” requires at least 51% cheese, while “prepared cheese product” may contain less.
Q: What is the main difference between processed cheese and natural cheese? A: Natural cheese is made from milk coagulation, while processed cheese blends natural cheese with additives and heat.
Q: Why do emulsifying salts need to be added to processed cheese? A: Emulsifying salts prevent fat and protein separation during melting, ensuring a smooth texture.
Q: Is American cheese considered real cheese? A: Products labeled “cheese food” or “cheese product” are not legally considered “real cheese” due to having less than 51% natural cheese.
Q: Is processed cheese healthier than natural cheese? A: Processed cheese often has higher sodium and can have a lower concentration of nutrients compared to natural cheese.
Q: Why does processed cheese have a longer shelf life? A: Pasteurization and added preservatives contribute to a longer shelf life.
Q: What counts as a “cup of dairy” for other dairy products? A: One cup of milk or yogurt counts as one dairy cup. For hard natural cheese, 1.5 ounces is one dairy cup.
