The Making of a Processed Cheese Cube
Processed cheese cubes are not simply blocks of pure, aged cheese. They are a manufactured product created by blending and heating natural cheeses with a variety of other ingredients. The process involves melting down different cheeses, along with emulsifying agents like sodium citrate, to achieve a uniform, smooth texture that melts easily without separating into oil and solids. This process is what gives them a distinctively soft, uniform consistency compared to the sometimes grainy or crumbly texture of natural cheese.
To ensure a long shelf life and prevent microbial growth, manufacturers also add preservatives, such as sorbic acid or nisin, and often a significant amount of extra salt. Permitted food colorings like annatto are also used to standardize the product's color. These additives are what make processed cheese cubes last for months without refrigeration (until opened), but they also contribute to the higher sodium levels and distinguish them nutritionally from their natural counterparts.
Processed vs. Natural Cheese: A Nutritional Showdown
The most significant differences between processed cheese cubes and natural cheese are found in their nutritional profiles. While both provide protein and calcium, the processing and additives in the cubes make for a less favorable nutritional balance, especially regarding sodium and saturated fat.
Here is a comparison highlighting the key differences:
| Feature | Processed Cheese Cubes | Natural Cheese (e.g., Cheddar) |
|---|---|---|
| Ingredients | Blended cheese, emulsifiers (e.g., sodium citrate), extra salt, preservatives (e.g., sorbic acid), food coloring | Milk, enzymes (rennet), salt, bacterial cultures |
| Sodium (per 100g) | Very High (e.g., ~1220-1420mg) | Lower, but still can be high (varies greatly) |
| Saturated Fat (per 100g) | High (e.g., ~16g) | High (comparable, but depends on fat content) |
| Additives | Yes (emulsifiers, stabilizers, preservatives) | No (typically) |
| Protein | Good source (~20g/100g) | Good source (~18-25g/100g) |
| Shelf Life | Extended, thanks to preservatives | Shorter, requires constant refrigeration |
The Health Trade-offs of Processed Cheese
While offering convenience and a source of protein and calcium, processed cheese cubes come with notable nutritional trade-offs. The high sodium content is a major concern, as excessive sodium intake is linked to high blood pressure, heart disease, and stroke. The saturated fat content is also significant, and though some research suggests the 'cheese matrix' may mitigate some of its negative effects, moderation is still advised, especially for those with cholesterol or heart health concerns. The presence of preservatives and other additives, while generally safe in regulated amounts, means you are consuming more than just milk solids.
On the other hand, for a quick and satisfying snack, or an addition to a meal, the calcium and protein can be beneficial. It's about context. An occasional cube is unlikely to derail a healthy diet, but relying on them as a daily staple is where potential issues arise due to the hidden sodium and fat. The key takeaway is to be aware of what you are consuming and how often.
Making Healthier Cheese Choices
If you enjoy cheese but want to minimize your intake of additives and high sodium, consider natural cheese. Options like fresh mozzarella, cottage cheese, feta, or aged cheddar often contain fewer preservatives and can be part of a healthy diet when consumed in moderation.
Here are some healthier ways to incorporate cheese into your snacking:
- Pair small cubes of natural cheddar or Gouda with apple slices for a balanced mix of sweet, tangy, and savory flavors.
- Thread cheese cubes with iced grapes and celery for a refreshing and hydrating snack.
- Add crumbled feta or fresh mozzarella to a salad or enjoy with cherry tomatoes and basil for a simple, fresh caprese salad.
- Opt for low-sodium or reduced-fat natural cheeses to keep salt and saturated fat in check.

Conclusion
So, are processed cheese cubes healthy? The answer is nuanced. As a source of calcium and protein, they offer nutritional value. However, their high sodium content, saturated fat, and added ingredients mean they are not the healthiest choice for regular consumption. Moderation is the key, and awareness of the nutritional differences between processed and natural cheese allows for more informed dietary decisions. For daily snacking, opting for smaller portions or transitioning to natural, less-processed cheese varieties is a healthier strategy.
