One medium banana provides about 1.3 g of protein; 100 g of banana has about 1.1 g.
Bananas are handy, portable, and sweet—but they are not a protein powerhouse. If you track macros, it helps to know exactly what you get from a typical piece. Below you’ll find clear numbers by size and serving, a comparison with other fruit, and smart pairings to boost the protein in a banana snack without losing ease or flavor.
Banana Protein By Size And Common Measures
Protein in bananas scales with weight. The figures below use lab-based nutrient data for raw fruit. Values are rounded for clarity.
| Serving | Typical Weight | Protein (g) |
|---|---|---|
| Extra Small Banana (Shorter Than 6 In) | 81 g | 0.9 |
| Small Banana (6–7 In) | 101 g | 1.1 |
| Medium Banana (7–8 In) | 118 g | 1.3 |
| Large Banana (8–9 In) | 136 g | 1.5 |
| Extra Large Banana (Over 9 In) | 152 g | 1.7 |
| 100 g Banana (Raw) | 100 g | 1.1 |
| 1 Cup Banana, Sliced | 150 g | 1.6 |
| 1 Cup Banana, Mashed | 225 g | 2.5 |
Those numbers show what most diet pros say: bananas are great for quick carbs, potassium, and vitamin B6, but they only add a small slice of daily protein. That makes pairing helpful when you want a more balanced snack.
How Much Protein Is In A Banana? Per 100 G, Per Piece, And Per Cup
For the exact phrase many search for—how much protein is in a banana—the answer depends on size. Per 100 g of banana you get about 1.1 g of protein. A medium piece lands near 1.3 g. A full cup of sliced banana comes out near 1.6 g, and a cup of mashed banana reaches roughly 2.5 g because it packs more fruit into the same volume.
Why Ripeness Barely Changes Protein
Ripeness shifts sugars and texture more than it changes protein. As bananas move from green to yellow and then spotty, starch converts to sugar and water content nudges up or down. Protein remains low and fairly steady across those stages, so the main driver is the weight of what you eat, not the color of the peel.
Bananas Vs Protein-Rich Foods
Protein density is where bananas come up short. A single egg packs about 6 g. A 170 g tub of strained yogurt can carry 15–17 g. An average handful of roasted peanuts adds roughly 7 g. That contrast helps with planning: use bananas for convenient energy, then add a protein source when you want staying power.
Protein In Bananas: Per 100 Grams And Per Serving
Ratios help. Bananas provide roughly one gram of protein per hundred grams, while also delivering fiber, potassium, and vitamin B6. If you aim for the widely cited daily protein target of about 0.8 g per kilogram of body weight, a banana supplies only a small fraction of that number, so it’s best treated as a carb-forward fruit with bonus nutrients.
How To Hit Protein Goals With Banana Snacks
Build a better snack by adding compact protein to your banana. Try a tablespoon or two of nut butter, a scoop of cottage cheese, or a pour of strained yogurt. Rolled oats, chia, or hemp hearts can help too. These small additions can lift a five-minute snack into the 10–20 g range without cooking.
Best Times To Use Banana Protein
Bananas shine around training, when you want easy carbs and a touch of protein. Before a workout, pair a banana with peanut butter so you aren’t eating on an empty stomach. After a workout, drink milk or a yogurt smoothie with your banana to help muscle repair.
Banana Forms And What Changes
Fresh fruit is the baseline used above. Other forms shift the macros:
Plantains And Cooking
Plantains are starchier cousins. Raw plantain sits around one gram of protein per 100 g, close to dessert bananas. Frying adds fat and calories without lifting protein, while boiling or baking mostly changes water weight.
Dried Banana And Chips
Drying removes water and concentrates nutrients per 100 g, so protein appears to rise when you compare equal weights. But a typical handful of chips is still a light protein serving. Scan labels for added sugar and oil.
Smoothies And Purees
Blending doesn’t change protein in bananas; it only changes volume. You can boost totals by blending a banana with milk, strained yogurt, or a scoop of whey or soy powder. Add ice or frozen fruit for a thicker texture.
Banana Protein In Context: Daily Needs And Smart Pairings
Most adults start near 0.8 g of protein per kilogram of body weight per day. Many active people, older adults, and those eating fewer calories choose a higher target. If a medium banana gives about 1.3 g, you can see why pairings matter when protein is the goal.

Banana Vs Other Fruits: Protein Snapshot
The numbers below are rounded values for raw fruit per 100 g, followed by a typical serving estimate. This puts banana protein in perspective next to common picks.
| Fruit | Protein (g/100 g) | Protein In A Typical Serving |
|---|---|---|
| Banana | 1.1 | Medium piece: ~1.3 g |
| Apple | 0.3 | One medium: ~0.5 g |
| Orange | 0.9 | One medium: ~1.2 g |
| Strawberries | 0.6 | 1 cup slices: ~1.0 g |
| Blueberries | 0.7 | 1 cup: ~1.1 g |
| Avocado | 2.0 | Half fruit: ~1.5 g |
| Grapes | 0.7 | 1 cup: ~0.8 g |
Size, Weighing, And Label Tips
Pick A Size Reference
Kitchen scales make the numbers simple. If you don’t have one, the standard “small/medium/large” sizes give a decent ballpark for logging food. Most tracking apps treat 118 g as “medium.” If your fruit is much shorter or thicker than your norm, shift the log to “small” or “large.”
Weigh Peeled Or Unpeeled?
When you weigh at home, weigh without the peel. Database entries for “raw banana” refer to the edible portion, not the peel. If you weigh the whole fruit, subtract the peel weight—about one-third for medium fruit—so your macros don’t drift.
Watch Product Labels
Packed items like banana chips or dried slices can vary a lot. Some add oil and sugar; some are plain. Label protein per 30 g or per ounce can look higher than fresh fruit per ounce because water is removed. Match like-for-like (by weight) when you compare.
Easy Ways To Add Protein To Banana-Based Meals
Five Quick Pairings
- Banana + 2 Tbsp Peanut Butter (about 7 g protein).
- Banana + 170 g Strained Yogurt (15–17 g).
- Banana + 30 g Mixed Nuts (4–6 g).
- Banana + 250 ml Milk (8 g).
- Banana + 2 Tbsp Hemp Hearts (6 g).
Balanced Smoothie Template
Blend one banana with 250 ml milk, 170 g strained yogurt, a handful of frozen berries, and ice. That mix lands in the 20–30 g range and works well as a quick breakfast or post-workout drink.
Overnight Oats Starter
Stir rolled oats, milk, and a spoon of chia in a jar. In the morning, mash in half a banana and add a scoop of protein powder or a dollop of strained yogurt. You’ll get creamy texture, steady carbs, and a clear bump in protein.
Method Notes And Sources
Protein values for bananas and other fruit are rounded figures drawn from datasets that trace back to laboratory analyses. Individual fruit will vary with variety, growing conditions, and ripeness. When precision matters, weigh your portion and consult a lab-sourced database.
You will see the exact phrase “how much protein is in a banana?” a few times above to match the query that brings readers here, but the piece stays people-first: numbers first, smart pairings next, and clear context on how to meet daily needs.
