Kraft Singles American Slice Nutrition — Quick Overview
Think of the square you layer on toasted bread. One piece weighs 19–21 grams. On average you get 50 calories, 3.5 grams of fat, 2 grams of saturated fat, around 210 milligrams of sodium, 3 grams of protein, roughly 2 grams of carbs, and a strong calcium boost. These figures come from the package panel and public label databases that aggregate brand data.
Kraft Singles Nutrition, At A Glance
This first table groups the most common styles so you can scan differences fast. Values are per slice and rounded; recipe tweaks and slice size can shift numbers a touch.
| Style | Calories | Key Nutrients |
|---|---|---|
| Original (21 g) | 50 | Saturated fat ~2 g • Sodium ~210 mg • Calcium ~290 mg |
| 2% Milk (19 g) | 45 | Saturated fat ~1.5 g • Sodium ~220 mg • Calcium ~260 mg |
| Fat Free (19 g) | 30 | Saturated fat ~0 g • Sodium ~260 mg • Calcium ~250 mg |
How These Numbers Were Chosen
The brand page lists 50 calories for a 21-gram original slice, which matches common packs. Independent label aggregators line up on the rest: roughly 3.5 grams fat, 2 grams saturated fat, about 210 milligrams sodium, 3 grams protein, and near 290 milligrams calcium per slice. Reduced fat versions trim calories and saturated fat. Fat free cuts fat to near zero and can raise sodium to keep flavor and melt.

Portion Picks And Real-World Totals
One slice works for a snack wrap. Two slices give you a classic melt. Four slices build a diner-style grilled cheese. Totals below help you plan your stack. Bread, butter, and fillings change the math, so weigh your recipe once and update.
| Serving | Calories | Sodium (mg) |
|---|---|---|
| 1 slice (original) | 50 | ~210 |
| 2 slices (original) | 100 | ~420 |
| 4 slices (original) | 200 | ~840 |
Protein, Calcium, And Melt
Each slice brings about 3 grams of protein. That modest hit helps sandwiches feel balanced next to carbs. Calcium lands near 20–25% of Daily Value per slice, which explains why these squares show up in lunch boxes. The signature melt comes from moisture, emulsifying salts, and a blend of dairy ingredients that keep the texture smooth when heated.
What Counts As A Serving
Scan the serving size line on the wrapper. For most packs it reads “1 slice,” set at 19–21 grams. Extra thin packs list two slices as one serving. Ultra thick packs push a single slice higher. If you switch pack sizes, recalc by grams rather than by slice count.
Salt: Where The Numbers Land
Processed American styles tend to sit in the middle for salt among sandwich cheeses. One orange square clocks in near 210 milligrams. The 2% milk version can nudge higher. Fat free often edges higher still. If you’re building a lunch that already includes salty meats or pickles, use one slice and lean on tomato or leafy greens for volume.
How Singles Compare With Natural Cheese
Sliced Cheddar or Swiss brings a higher protein count per ounce along with more fat and less moisture. The pasteurized style trades a bit of protein for an easy melt and even texture, which helps for fast breakfasts and weeknight melts. If you want a lower-fat sandwich without switching to fat free, pick the 2% milk slice and toast longer to coax melt without extra butter.
Label Reading Tips
Check The Weight
Two packs can look identical yet list different slice weights. That’s why calories per slice can swing by 5–10 points. The grams line is the one to trust.
Scan Saturated Fat
Original sits near 2 grams per slice. Two slices take you to about 4 grams. The 2% milk slice trims that by a third. Fat free drops it to near zero, though melt and mouthfeel change.
Watch Sodium
One slice hovers around 200–260 milligrams depending on style. If you’re stacking meats, cap the cheese at one slice and add herbs or mustard for punch instead of extra salt.
Spot Calcium
The calcium line is a bright spot here. Numbers often land around 250–290 milligrams per slice. That makes these squares a handy way to nudge daily intake when you’re short on dairy.
Smart Swaps And Uses
Quick Sandwich Ideas
Toast one slice of bread, lay a single square, and crown with warm turkey or a veggie patty. The heat softens the slice so you get the melt without pan butter. In breakfast wraps, fold a triangle to fit a tortilla and let the eggs finish the melt.
Grilled Cheese Tactics
Use two slices for the classic sandwich. For a richer melt, add a thin layer of shredded Cheddar between them. If you want fewer calories, switch one slice to the 2% milk version and pan-toast longer on low heat.
Burgers And Hot Sandwiches
Place a square on the patty for the last 30 seconds of cooking and cover the pan to trap steam. For a deli-style hot ham sandwich, spread a light smear of mustard and add a ring of red onion to brighten the bite.
Allergen Note And Storage
These slices contain dairy. Keep the pack chilled and sealed to prevent drying. If the plastic sticks or the slice looks torn, discard it. In late 2023 the brand reported a short recall tied to wrapping film; older packs with specific dates were flagged, and the equipment issue was fixed. If you’ve stored a box for months, scan the date and lot panel before serving.
