One slice of American cheese typically has about 60–95 calories, with fat and sodium driving most of the totals.

American Cheese Nutrition Facts Overview
Processed slices sit in a middle ground between cheese and cheese food. The core method blends one or more natural cheeses with emulsifying salts and heat into a uniform slice that melts cleanly. The federal standard of identity calls this “pasteurized process cheese.” It sets guardrails for moisture, milk fat, and approved emulsifiers, which is why slices behave the same across brands. This process cheese standard spells out the method and ingredient limits.
From a numbers angle, the range is tight once you match portion sizes. A deli ounce lands near 94 calories with roughly 5 grams of protein, 7 grams of fat, and around 360 milligrams of sodium. A thinner 20–21 gram single sits closer to 50–66 calories with about 3 grams of protein and 230–260 milligrams of sodium, depending on the brand. These figures reflect the current USDA nutrient table and widely sold labels.
Standard Portions And Macro Snapshot
To make sense of panels, line up equal weights. Below you’ll see per-slice and per-100-gram values based on the same sources. Values are rounded for kitchen use.
| Nutrient | Per Slice (20–21 g) | Per 100 g |
|---|---|---|
| Calories | 50–66 | 330 |
| Protein (g) | 3–3.5 | 16.9 |
| Total Fat (g) | 4–5.5 | 25.6 |
| Saturated Fat (g) | 2–3 | 15.1 |
| Carbohydrate (g) | 1–2 | 8.6 |
| Sodium (mg) | 230–260 | 1,284 |
| Calcium (mg) | 110–140 | 682 |
These values reflect plain slices. Add-ins like peppers or bacon bits shift sodium and calories a little. Recipes can change too, so glance at the current panel when you shop.
How This Slice Fits A Balanced Plate
Dairy brings protein, calcium, and vitamin D fortification in many slice styles. The flip side is saturated fat and salt. If you want the flavor without going overboard, think portion and pairing. One slice on a burger with lettuce, tomato, and a whole-grain bun keeps balance. Two slices on grilled cheese can still land well if you swap in low-salt bread and add a side salad.
That daily sodium cap matters for sandwiches. A couple of slices with deli meat can climb fast. Check the bread panel and condiments, then adjust. The American Heart Association caps intake at 2,300 milligrams, with a 1,500-milligram goal for many adults. The AHA sodium guidance lays out the range clearly.
Protein, Calcium, And Sat Fat—What To Weigh
Protein per slice is modest but steady. Plan on 3–5 grams based on thickness. Calcium is strong, landing near 20% Daily Value per ounce. Saturated fat tracks with melt and mouthfeel, so richer slices bring more. If your day already includes eggs, sausage, or pizza, go with a lighter cheese pick at lunch.
Regular Vs Reduced-Fat Vs Singles
Reduced-fat process slices trim fat and calories while holding melt. A common label shows 80 calories per 28 grams with 6 grams of protein and 280 milligrams of sodium. Standard deli slices run near 94 calories per ounce. Singles vary across brands; many list 50–60 calories per 20–21 grams. Data below line up common picks so you can swap without guesswork.
| Style | Calories | Protein (g) |
|---|---|---|
| Regular Deli, 28 g | ~94 | ~5 |
| Singles, 21 g | 50–60 | ~3 |
| Reduced-Fat, 28 g | 80 | 6 |
If you’re tracking calories, the gram line on the label is your friend. Match servings by weight and the math stays honest across brands.
Label Terms And Standards, Made Simple
The “pasteurized process cheese” name signals a blend of cheese plus emulsifying salts heated into a smooth mass. The rule lives in federal code and outlines how much moisture and milk fat are allowed, along with which emulsifiers can be used. It’s the reason a square from one brand melts about the same as another. The process cheese standard gives the legal backbone if you want the fine print.
What About “Cheese Food” Or “Imitation”?
Labels vary. “Cheese food” blends in dairy ingredients like whey or milkfat and runs slightly different limits. “Imitation” drops dairy for other fats or starches. The melt and numbers won’t match the tables above, so scan the panel and compare per 100 grams when in doubt. The USDA nutrient table covers many variants if you need a baseline.
Smarter Sandwich And Snack Swaps
Better Buns And Bread
Pick bread with 140 milligrams of sodium or less per slice. That single tweak keeps room for a cheese square and still leaves space in your daily budget.
Fresh Boosters
Layer tomato, pickles, or a crunchy slaw for bite and moisture so you don’t lean on extra cheese for flavor. A drizzle of mustard brings tang without many calories.
Heat Moves For A Cleaner Melt
Cover the pan to trap steam for thirty seconds near the end of cooking. That softens the slice fast, which means you can stick to one slice and still get the stretch you want.
Method Notes And Data Sources
Values come from the current USDA nutrient table for pasteurized process American cheese and a sample of brand panels. Portions were normalized to 20–21 grams, 28 grams, and 100 grams for apples-to-apples reading. For brand specifics, the Kraft Singles page lists the per-slice numbers. The USDA table shows the full per-100-gram profile, including calcium, vitamin D, and sodium.
