Apple slices contain trace protein—about 0.26 g per 100 g—so each slice adds only a few hundredths of a gram.
Curious how much protein you’re getting from a plate of crisp, sweet slices? Here’s a clear, data-backed look at what’s in those wedges, how to estimate amounts at home, and smart ways to round out a snack so it actually moves the needle on daily protein goals.
Protein In Sliced Apples: Quick Reference
The protein content of fresh apples is small. Standard nutrition databases list roughly 0.26 g protein per 100 g of raw apple with skin. A medium whole fruit (about 182 g) lands near 0.47–0.50 g protein. One cup of slices weighs close to 109 g, which comes out near 0.28–0.29 g protein. These figures come from the USDA-linked dataset presented on MyFoodData, which lets you switch among common serving sizes for apples, raw, with skin.
What “Per Slice” Looks Like In Real Life
Most people cut a medium piece of fruit into 8–12 wedges. If a medium one weighs ~182 g, each wedge ranges around 15–30 g depending on thickness. Since protein is just 0.26% by weight, each slice delivers only about 0.04–0.08 g protein. That’s measurable, but tiny.
Core Numbers At A Glance
Use this compact table early while you read. All values refer to raw fruit with skin unless noted.
| Serving | Approx. Weight | Protein (g) |
|---|---|---|
| 100 g Raw Apple | 100 g | 0.26 |
| 1 Medium Whole Fruit | 182 g | ~0.47 |
| 1 Cup Slices | 109 g | ~0.28 |
| 1 Large Whole Fruit | 223 g | ~0.58 |
| 1 Small Whole Fruit | 149 g | ~0.39 |
| 1 Cup Unsweetened Applesauce | 244 g | ~0.25–0.30 |
Notice the pattern: bigger portions raise the total grams, but the ratio stays low. Apples shine for fiber and water; protein is minimal.
How To Estimate Protein From Your Plate
You don’t need a lab. A quick kitchen method gets you close enough for everyday tracking.
Step-By-Step Estimation
- Pick Your Base. Use 0.26 g protein per 100 g raw fruit with skin.
- Weigh Or Approximate. A medium whole fruit is ~182 g. One cup of slices is ~109 g on the USDA-linked database above.
- Do A Fast Multiply. Weight (in grams) × 0.0026 = grams of protein.
- Slice Math. If you cut a medium piece into 8 wedges, each is ~23 g, so protein per wedge is 23 × 0.0026 ≈ 0.06 g.
Why Estimates Vary
Varieties differ in water and sugar. Peel adds a pinch of weight and amino acids. Slice thickness changes the wedge weight a lot. That’s why using a food scale—or sticking to “cup of slices” or “medium whole fruit”—keeps your log consistent.
How This Fits Into Daily Protein Targets
Nutrition labels in the United States use a Daily Value of 50 g protein. You’ll see that figure in FDA education materials such as the agency’s interactive handout on protein for the Nutrition Facts label: Daily Value for protein. With that yardstick, even a full cup of slices contributes well under 1% of a 50 g day.
Protein Goals In Plain Terms
Many adults aim near the 0.8 g per kilogram bodyweight guideline for maintenance, while athletes or very active folks often aim higher. Apples can round out a snack, but they won’t carry the protein load. Pair them with foods that do.
Turn A Plate Of Slices Into A Protein-Smart Snack
Fruit is easy, portable, and tasty. Add one item from the list below and you’ll turn a light bite into something that actually supports muscle repair and lasting fullness.
Quick Pairing Ideas
- Greek Yogurt. Plain, strained styles pack 12–18 g per 170 g tub.
- Nut Or Seed Butter. Two tablespoons bring 6–8 g; great on wedges.
- Cottage Cheese. A half cup often lands around 12–14 g.
- Cheddar Or Swiss. Thin slices add 6–7 g per ounce.
- Roasted Chickpeas. Toss a handful on a salad with apple slices for 5–7 g.
Small Adjustments That Help
- Keep The Peel On. More fiber, same effortless prep.
- Balance The Plate. Add a protein and a little fat to slow digestion.
- Watch Sweetened Dips. Caramel and sugary yogurts pile on calories fast.
Apple Slice Protein: Practical Models
Here are simple scenarios based on common ways people cut fruit at home. Use them as templates for your log.
| Scenario | Per Slice Weight | Protein Per Slice |
|---|---|---|
| Medium Fruit, 8 Wedges | ~23 g | ~0.06 g |
| Medium Fruit, 10 Wedges | ~18 g | ~0.05 g |
| Medium Fruit, 12 Wedges | ~15 g | ~0.04 g |
| Large Fruit, 8 Wedges | ~28 g | ~0.07 g |
| Small Fruit, 8 Wedges | ~19 g | ~0.05 g |
| 1 Cup Slices (All Pieces) | 109 g total | ~0.28–0.29 g total |
How To Use The Models
Pick the setup that matches your cutting style. If you’re between sizes, round to the closest weight and keep the same method every time. Consistency beats false precision.
Raw Slices Vs. Other Apple Forms
Protein stays low across forms. Unsweetened sauce per cup still comes in under a third of a gram. Dried pieces lose water and concentrate carbs, but protein remains modest. If protein is the goal, the best move is pairing, not swapping forms.
Quick Math Cheatsheet
Convert Weight To Protein
Protein (g) ≈ Fruit Weight (g) × 0.0026
Examples that map to common portions:
- 15 g wedge: 15 × 0.0026 ≈ 0.04 g
- 23 g wedge: 23 × 0.0026 ≈ 0.06 g
- 109 g cup of slices: 109 × 0.0026 ≈ 0.28 g
- 182 g medium whole: 182 × 0.0026 ≈ 0.47 g
Where These Numbers Come From
The serving sizes and nutrient values above reflect the USDA-linked database presented on MyFoodData for raw fruit with skin. You can verify the figures—and toggle between “100 g,” “medium,” and “1 cup slices”—on the database page for apples. For label context, the FDA materials explain how the Nutrition Facts panel treats protein and what “% Daily Value” means. A handy primer is the agency’s PDF on the 50 g Daily Value for protein.
Smart Ways To Build A Protein-Aware Snack
Here’s a simple blueprint for a snack that’s tasty and balanced.
Pick One From Each Column
- Base: 1 cup of slices (0.28–0.29 g protein).
- Protein: ¾ cup Greek yogurt, 2 tbsp peanut butter, ½ cup cottage cheese, or an ounce of cheese.
- Crunch Or Spice: Cinnamon, toasted walnuts, pumpkin seeds, or a dash of cardamom.
This keeps the fruit’s fiber while adding enough protein to matter. It also stretches fullness far longer than fruit alone.
Method Notes And Limits
Numbers are rounded for readability. Apples vary by variety and season. If you need tighter tracking—for a medical plan or athletic target—use a kitchen scale and stick with weighed portions. For general wellness, the models above are more than sufficient.
Bottom Line For Trackers
Fresh slices bring flavor, crunch, and fiber. Protein is present but tiny. If you love fruit at snack time, keep it—and add a side that supplies several grams of protein in one shot. That simple move gets you closer to a daily total that matches your goals.
