One medium apple contains about 0.5 grams of protein, based on USDA data.
Apples bring fiber, water, and a light hit of micronutrients. Protein isn’t their calling card. If you’re tracking macros or balancing a snack, it helps to know the exact range by size and how that stacks up against a day’s needs. Below you’ll find clear numbers, quick comparisons, and smart pairing ideas—all based on standard reference data.
Protein In A Medium Apple: By Size And Variety
Lab-reference values for raw apples with skin sit near 0.26 g protein per 100 g. Serving sizes vary a lot, so the grams of protein change with weight. The figures below use the USDA method for converting per-100-gram data to real-world portions (N = V × W ÷ 100).
Protein By Common Apple Portions
| Serving | Weight (g) | Protein (g) |
|---|---|---|
| 100 g (reference) | 100 | 0.26 |
| 1 medium (3" dia) | 182 | 0.47 |
| 1 large (3 1/4" dia) | 223 | 0.58 |
| 1 small (2 3/4" dia) | 149 | 0.39 |
| 1 cup slices | 109 | 0.28 |
| 1 cup, chopped | 125 | 0.33 |
Why the range? Water content and fruit size shift the totals. Sweet, crisp types like Fuji or Gala land near the same protein per 100 g, so the main driver is weight, not variety.
How These Numbers Were Calculated
The protein baseline comes from standard reference entries for raw apples with skin. Conversions from per-100-gram values to household servings use the USDA’s published formula for portions (N = V × W ÷ 100). For context on label math and daily references, see the FDA’s guidance on Daily Values and its protein education sheet, which also explains why %DV for protein often doesn’t appear on a label.

What That Means For Your Day
The nutrition label framework uses a Daily Value of 50 g protein for general guidance on a 2,000-calorie diet. A medium apple’s ~0.47 g protein is under 1% of that. In other words, fruit is a light contributor to your daily protein target. It still earns a spot for fiber and hydration, but you’ll need other foods to carry the protein load at meals and snacks.
How To Hit A Protein Target With Apples In The Mix
Pair an apple with a protein-rich side. Here are simple combos that keep prep low and taste high:
- Apple + Greek yogurt (plain or lightly sweetened)
- Apple + cottage cheese and cinnamon
- Apple + peanut or almond butter (2 tbsp measured)
- Apple + sharp cheddar cubes
- Apple + roasted chickpeas or a small handful of nuts
Protein Math Without The Jargon
Curious how those portion values in the first table were set? Here’s the simple version.
The Per-Portion Equation
Protein per portion = (protein per 100 g) × (portion weight in g) ÷ 100
Using 0.26 g per 100 g as the baseline and a 182 g fruit:
0.26 × 182 ÷ 100 = 0.47 g
That’s the same approach used by nutrient databases and label calculators.
What About Peeled Fruit Or Applesauce?
Peeling changes fiber more than protein. Protein stays near that quarter-gram per 100 g mark. Applesauce sits in the same ballpark per 100 g unless sweeteners or other ingredients are added. The shift you’ll notice most is carbs and fiber, not protein.
Apples, Protein Quality, And %DV
%DV for protein on a label isn’t always shown. The FDA only requires it when a protein claim is made or for certain children’s foods, and it must account for protein quality. Whole fruit isn’t sold for protein claims, so most packs skip %DV and list grams only.
If you still want to gauge the share of a day’s protein from a serving of fruit, you can do the quick math using the 50 g Daily Value. The second table lays it out.
Protein In Apples As A Share Of Daily Value
| Serving | Protein (g) | %DV (50 g) |
|---|---|---|
| 1 medium (182 g) | 0.47 | 0.9% |
| 1 large (223 g) | 0.58 | 1.2% |
| 1 small (149 g) | 0.39 | 0.8% |
| 1 cup slices (109 g) | 0.28 | 0.6% |
| 100 g | 0.26 | 0.5% |
How Apples Fit A Protein-Aware Day
The RDA for healthy adults centers on 0.8 g protein per kilogram body weight. That’s a starting point; athletes, older adults, and some life stages may aim higher. Apples help with fiber and volume, which can make higher-protein foods feel more balanced in a meal. Use fruit to round out texture, freshness, and potassium while your main protein comes from beans, lentils, soy foods, dairy, eggs, fish, or meats—choose what suits your diet.
Smart Snack Templates
- Crunch & Creamy: Sliced apple over thick yogurt with chia and a drizzle of honey.
- Sweet & Salty: Apple wedges with sharp cheddar or a small turkey roll-up.
- Plant-Powered: Apple with a protein bar that lists 10–20 g protein and short ingredient lines.
- Desk-Friendly: Whole apple, 2 tbsp nut butter packet, and sparkling water.
Answers To Common Reader Checks
Does Variety Change Protein Much?
Not by much. Red Delicious, Fuji, Gala, Granny Smith, and Honeycrisp sit near the same per-100-gram figure. The bigger factor is fruit weight. If you weigh the apple, the per-portion math in the first table holds steady.
What If I’m Watching Protein Closely?
Build each meal around a solid protein source, then layer fruit for fiber and flavor. Aim for protein across breakfast, lunch, dinner, and snacks rather than saving it for one sitting. That pattern makes it easier to meet a daily target without changing your entire menu.
Quick Reference: How To Read An Apple’s Label
- Protein line: You’ll see grams, often without %DV—by design.
- Serving size: Units like “1 medium” link back to standard weights.
- Fiber callout: Apples shine here; that’s where the macro value sits.
Takeaways You Can Use Today
- A medium apple brings roughly half a gram of protein—use it for fiber and freshness, not protein.
- Portion weight drives the small swings in protein per fruit.
- To meet a daily target, pair fruit with yogurt, cottage cheese, nut butter, tofu, eggs, fish, meats, or legumes.
- Use the simple equation (per-100-g × weight ÷ 100) to convert any database value to your exact portion.
