Banana protein per 100g is about 1.09 g, based on USDA-linked data for raw bananas.
Looking for a straight answer on banana protein per 100g? You’re in the right spot. This guide gives you the number that matters, then adds context you can use in the kitchen, at the gym, or while tracking macros. We’ll keep the math simple, show how ripeness and drying change the count, and compare bananas with other fruit. You’ll also see smart ways to pair a banana with protein so a quick snack turns into a more balanced bite. No filler—just clear figures and steps you can put to work today.
The short story is that bananas are a carb-forward fruit with a pinch of protein. That pinch stays steady across common varieties, yet it shifts when moisture changes. Drying removes water and concentrates every nutrient, protein included. Mashing into a smoothie can move the dial too, depending on what you add. By the end, you’ll know exactly how to log banana protein per 100g and how to turn a banana into a better protein teammate.
Banana Protein Per 100G: Raw, Ripe, And Dried
Across datasets built on USDA methods, raw banana sits around 1.09 grams of protein per 100 grams. That figure comes from samples of ripe or slightly ripe fruit without the peel. Overripe samples land in the same ballpark, with tiny swings tied to water content. Plantain, a starchier cousin, is similar by weight in the raw state. Drying removes water, so dried banana or banana powder shows a higher number per 100g even though the banana itself didn’t “gain” protein—the water just left.
| Form (100g Edible) | Protein (g) | Notes |
|---|---|---|
| Banana, raw (ripe/slightly ripe) | ~1.09 | Reference value from USDA-based data. |
| Banana, overripe, raw | ~0.73–1.1 | Moisture can nudge the figure a bit. |
| Banana, baby/mini, raw | ~1.0–1.1 | Size changes volume, not density. |
| Plantain, raw | ~1.3 | Close cousin; slightly higher per 100g. |
| Banana, dried (chips, low-fat) | ~3.5 | Water loss concentrates nutrients. |
| Banana powder (dehydrated) | ~3.9 | Values vary by process and brand. |
| Banana purée (no sugar) | ~1.0 | Blend of raw fruit; depends on added water. |
You can verify the raw 100g figure in datasets that mirror the USDA FoodData Central entries for “bananas, raw.” A practical summary appears on MyFoodData’s “bananas, raw” page, which draws from the same backbone as USDA records. For methods and data families, see the FoodData Central documentation that describes how Foundation Foods and SR Legacy values are built.
Why Per 100G Beats Guesswork
Labels and apps often list nutrition per serving. With fresh fruit, serving size swings from one banana to the next. Weighing peeled fruit fixes that. One hundred grams gives a stable yardstick, so a small half banana and a large one can be logged fairly. If you don’t own a scale, use volume as a backup: one cup of sliced banana is roughly 150 grams; two-thirds cup lands near 100 grams.
How Ripeness And Water Change The Number
Protein lives in the fruit’s cells. When a banana softens, water and sugars shift, yet protein grams stay close per 100g. What does change is the ratio of water to solids. Overripe samples may show slightly lower protein per 100g if water content creeps up, and slightly higher if water drops. That is why sources present a narrow range, not a fixed integer.
Banana Protein Per 100G In Real Meals
On its own, 100 grams of banana only brings about a gram of protein. That’s fine for a quick carb top-up, but it won’t carry a snack. The trick is pairing. Match a banana with dairy, soy, eggs, or nuts, and the protein jumps while the fruit adds potassium and vitamin B6. If you lift, run, or cycle, these pairings keep energy steady and support repair.
Practical Pairings That Raise Protein
Try these simple combos that stick to common pantry items. Each idea references 100 grams of banana, then layers a protein base so you can tweak totals without odd math.
- Greek yogurt bowl: Stir 100 g banana into 170 g plain Greek yogurt. Add cinnamon and a sprinkle of oats.
- Peanut butter toast: Top whole-grain toast with 2 tbsp peanut butter and 100 g banana slices.
- Eggs and banana oats: Cook oats with milk, then whisk in one egg off heat; fold in 100 g banana.
- Soy smoothie: Blend 100 g banana with 240 ml soy milk and a scoop of whey or pea powder.
- Cottage cheese cup: Combine 100 g banana with 150 g cottage cheese; add a dash of cocoa.
Amino Acids: What You Get
Banana protein carries all common amino acids in small amounts, with more aspartic and glutamic acids among the non-essential group. Per 100 g, the totals are low, so a banana can’t meet daily protein targets on its own. Treat it as a carb source that helps you hit calorie and micronutrient goals while your main protein comes from dairy, meat, eggs, soy, or legumes.
How Banana Protein Per 100G Compares With Fruit
Fruit protein varies, yet most sit near the 0.5–1.5 g range per 100 g. Bananas land near the top of that narrow band, yet still trail protein-leaning picks like guava. Dried forms of fruit almost always show higher protein per 100 g because water is gone. That bump doesn’t make dried fruit a “protein food,” but it does change the math when you build trail mix or a bar.
| Fruit (100g) | Protein (g) | Quick Note |
|---|---|---|
| Banana, raw | ~1.09 | Reference point in this guide. |
| Apple, raw | ~0.3 | Lower protein per 100 g. |
| Orange, raw | ~0.9 | Close to banana by weight. |
| Grapes, raw | ~0.6 | Light across the board. |
| Guava, raw | ~2.6 | High among fruits per 100 g. |
| Plantain, raw | ~1.3 | Similar family, slightly higher. |
From 100G To Common Portions
One medium banana without the peel weighs about 118 grams. That puts protein near 1.3 grams for the whole fruit. A small banana can sit near 90–100 grams, while a large one can pass 135 grams. If you prep ahead, slice and freeze in 100-gram bags so you can drop a ready portion into a smoothie without re-weighing.
Reading Dried Banana Labels
Dried banana looks protein-dense per 100 g, yet serving sizes are small. Chips can include oil, sugar, or both, which raises calories without adding protein. Banana powder varies by process and brand, so check the label and scan for added sugar. If you need more protein, treat dried banana like a carb add-in and pair it with nuts or yogurt, not as the protein source.
Data Sources And Simple Method
Numbers in this article come from datasets that reflect USDA FoodData Central records for raw bananas, plantain, and dried forms, plus compilers that pull the same references into readable charts. Sampling varies across seasons and regions, so small swings show up. For logging and meal planning, the per-100 g figure for bananas is consistent enough to hold up in daily use.
Quick Logging Rules That Keep You Accurate
- Weigh bananas after peeling so water in the peel doesn’t skew the count.
- Use 1.09 g protein per 100 g as your default for raw banana.
- Flag dried banana as ~3.5–3.9 g per 100 g, and keep servings modest.
- Note add-ins in smoothies. Milk, yogurt, soy, or whey change totals far more than the fruit.
- When eating out, estimate 100–120 g for a small banana and 120–135 g for a medium one.
Make Banana A Better Protein Teammate
If you’re cutting, keep the banana and shift the base. Greek yogurt, skyr, cottage cheese, tofu, or a scoop of whey turns a 1 g fruit into a 20–30 g snack with stronger satiety. If you’re bulking, add oats and nut butter so carbs and calories climb on purpose. In both cases, add a pinch of salt when you sweat; bananas supply potassium, but the mix needs sodium too.
Sample Builds With Macros
- Banana skyr cup: 100 g banana + 170 g plain skyr ≈ 20–25 g protein, steady carbs, low fat.
- Whey smoothie: 100 g banana + 240 ml milk + 30 g whey ≈ 30 g protein, quick prep.
- Peanut butter oats: 100 g banana + 40 g oats + 2 tbsp peanut butter ≈ 14–18 g protein, dense calories.
- Tofu shake: 100 g banana + 150 g silken tofu + soy milk ≈ 20 g protein, dairy-free.
Clear Takeaways For Daily Use
Log banana protein per 100g at 1.09 grams for raw fruit. Expect small shifts with ripeness and water. Dried banana shows a higher number by weight because the water is gone. If protein is the goal, pair a banana with dairy, eggs, soy, or legumes. Keep your scale handy, save 100-gram freezer packs for smoothies, and use the tables above when you batch-cook snacks for the week.
