What's Really in Your Bag of Grated Cheese?
It’s a common sight in the supermarket—convenient bags of pre-grated cheese. They save time and effort, making meal prep a breeze. But lurking beneath the surface of this convenience is a question that has sparked concern among health-conscious consumers: Is grated cheese unhealthy? The primary difference between pre-grated and block cheese lies in the additives used to prevent the shreds from clumping together.
These anti-caking agents, which can include powdered cellulose, potato starch, and cornstarch, are key to maintaining the cheese's texture and shelf stability. While the use of “wood pulp” (cellulose) in shredded cheese has been the subject of viral internet claims and fear-mongering, food scientists and dietitians generally agree that these additives are safe for consumption. The U.S. Food and Drug Administration (FDA) has classified cellulose as "generally recognized as safe" (GRAS). However, the presence of these additives does affect the cheese's properties, particularly its melt and texture, which some foodies argue compromise the overall quality.
Comparing Grated Cheese vs. Block Cheese
To understand the true health implications, it's helpful to compare the two forms of cheese across different aspects. While the core nutritional profile is largely similar, the differences in processing and additives are what set them apart.
Nutritional Profile
From a macronutrient standpoint, a block of cheddar and a bag of pre-shredded cheddar are very similar in terms of calories, protein, and fat. The anti-caking agents are added in such small, negligible quantities that they have almost no impact on the overall nutritional value. For instance, cellulose is a form of dietary fiber that simply passes through the digestive system. In contrast, starches contribute a minimal amount of carbohydrates. For those on very low-carb diets, such as keto, the small carb content from starches might be a minor consideration.
Additives and Processing
This is where the most significant difference lies. Block cheese is simply the cheese itself, while pre-grated cheese undergoes additional processing. The anti-caking agents are applied to the shreds after grating. Some brands also include preservatives like natamycin to inhibit mold growth and extend shelf life. While these additives are deemed safe, some consumers prefer to avoid them, opting for the more natural, unprocessed block cheese.
Melt and Texture
The anti-caking agents in pre-grated cheese are designed to prevent clumping by absorbing moisture. While effective for keeping the shreds separate in the bag, this same property can hinder its ability to melt smoothly and evenly when cooked. This often results in a grittier, less creamy texture in sauces, pizzas, and other dishes. Freshly grated cheese, with its higher moisture content and lack of additives, melts into a smooth, decadent texture that many chefs and home cooks prefer.
Flavor
While some people report a slightly grainy, dusty taste from the anti-caking agents, the flavor impact is generally minimal. The more noticeable difference comes from freshness. Freshly grated cheese, used immediately after shredding, offers a more vibrant, authentic cheese flavor that hasn't been muted by a lengthy shelf life.
Grated vs. Block Cheese: A Comparison
| Feature | Grated Cheese | Block Cheese |
|---|---|---|
| Convenience | High - Ready to use | Low - Requires manual grating |
| Additives | Contains anti-caking agents (cellulose, starches) and sometimes preservatives | Generally contains no added anti-caking agents |
| Melting Performance | Can melt unevenly, sometimes with a grainy texture | Melts smoothly and creamier |
| Nutritional Impact | Minimal, negligible difference; adds small amounts of carbs/fiber | Standard nutritional profile of the specific cheese variety |
| Flavor | Can have a slightly muted flavor or powdery taste | Fresher, more authentic cheese flavor |
| Cost | Often more expensive per ounce | More economical per ounce |
| Shelf Life | Can last longer due to lower moisture and preservatives | Shorter shelf life once opened |
Making a Healthier Choice
Ultimately, deciding between grated and block cheese comes down to personal priorities, balancing convenience with culinary and health considerations. For those with no specific dietary restrictions, the health difference is so minimal that convenience often wins out. However, if you are a food enthusiast, the superior melt and flavor of freshly grated cheese from a block is hard to beat. For budget-conscious shoppers, grating your own is typically more cost-effective in the long run.
To make the healthiest choice for you, consider these points:
- Prioritize Freshness: For the best flavor and texture, particularly in recipes where melt is key, grating from a block is the superior option. This ensures you are consuming a product with no added fillers or preservatives.
- Read the Label: If you opt for pre-grated cheese, check the ingredients list. You will likely find cellulose, potato starch, or other anti-caking agents listed. While safe, being aware of what you are eating is always a good practice.
- Consider Additive Impact: While the health risk is not significant for most people, some individuals may experience minor digestive issues like bloating with high cellulose intake, though this is rare with the small amounts in cheese.
- Control Your Portions: Regardless of the form, cheese is calorie-dense and high in saturated fat and sodium. The biggest health consideration for any cheese is overall consumption, not the minor additives in the pre-grated variety.
- Store Properly: If grating your own, store the unused block of cheese properly wrapped in parchment or waxed paper to prevent mold and extend its freshness.
In conclusion, while the rumors of grated cheese being "toxic" or full of dangerous fillers are largely unfounded, it is not as pristine as block cheese due to the use of anti-caking agents. The health impact of these additives is minimal, and the primary differences relate to texture, melt, flavor, and cost. By understanding these distinctions, consumers can make an informed decision that best fits their lifestyle, budget, and culinary preferences. While there's no major health risk, for the best taste and experience, grating your own from a block is the way to go.

Frequently Asked Questions
Is cellulose in grated cheese actually wood pulp?
Yes, food-grade cellulose is derived from wood pulp or other plant fibers. However, it is processed and considered a harmless, indigestible dietary fiber that is approved as safe by the FDA.
Does grated cheese have more calories than block cheese?
The calorie difference is negligible. Any minor increase comes from starches used as anti-caking agents, but the overall nutritional profile is nearly identical to block cheese.
Why doesn't grated cheese melt as smoothly as block cheese?
Anti-caking agents like cellulose absorb moisture and prevent the shreds from clumping in the bag. This same property hinders the cheese's ability to melt smoothly and completely when heated.
Are there any other additives in pre-shredded cheese?
Some pre-shredded cheeses may contain other additives like potato starch or natamycin, which is used to prevent mold. Always check the ingredient list for specific product details.
Is pre-shredded cheese more expensive than block cheese?
Yes, pre-shredded cheese is often more expensive per ounce than purchasing a block of cheese and grating it yourself. You are paying for the convenience of the processing.
Can eating too much cellulose from grated cheese cause health issues?
The amount of cellulose in grated cheese is so small that it is unlikely to cause any health issues. Excessive, intentional consumption of cellulose could potentially cause bloating, but this is not a concern from normal dietary intake.
What is the healthiest choice: block or grated cheese?
For the most natural, additive-free option, block cheese is the healthier choice. However, the health difference is minimal for most people, and the decision often comes down to convenience, taste, and personal preference.
