The Calorie-Dense Plantain
While most people picture the common yellow Cavendish banana, the plantain is actually the variety that packs the most calories per serving, especially when cooked. Plantains are part of the same genus as dessert bananas (Musa) but are larger, starchier, and less sweet. While raw dessert bananas average around 89 calories per 100 grams, raw plantains contain approximately 122 calories per 100 grams, a difference primarily attributed to higher carbohydrate content.
Unlike dessert bananas, plantains are almost always cooked before consumption. The method of preparation profoundly impacts the final calorie count. For example, frying plantains, a common preparation method, significantly increases their caloric value due to the absorption of oil. A cup of cooked plantains can range from 180 to 230 calories or more, depending on the preparation. This makes cooked plantain the definitive winner for the title of 'highest calorie banana.'
Common Dessert Bananas: A Closer Look
The banana you typically find in supermarkets is the Cavendish variety. Its calorie count is primarily determined by its size and ripeness.
- Extra Small (<6 inches): Approx. 72 calories
- Medium (7-8 inches): Approx. 105 calories
- Extra Large (>9 inches): Approx. 135 calories
Other varieties of dessert bananas, such as Red bananas or Lady Finger bananas, have slight variations in nutritional content but generally fall within a similar calorie range to the Cavendish variety on a per-gram basis.
The Role of Ripeness
The ripeness of a banana affects the type of carbohydrates it contains, but not the overall calorie count significantly.
- Unripe (Green) Bananas: Contain more resistant starch, a type of fiber that isn't fully digested and acts as a prebiotic. This results in a slower release of glucose and a lower glycemic index. For instance, a medium unripe banana might have around 89 calories.
- Ripe (Yellow) Bananas: As a banana ripens, its resistant starch converts into natural sugars like glucose and fructose. This makes it sweeter and easier to digest. A medium ripe banana has slightly more calories, at approximately 105, but the overall difference per 100 grams is minor.
Comparison of Banana Varieties and Preparation Methods
| Type of Banana / Preparation | Approximate Calories (per 100g) | Primary Calorie Source | Notes |
|---|---|---|---|
| Raw Dessert Banana (Ripe) | 89 kcal | Sugar | Typical supermarket banana. |
| Raw Plantain (Unripe) | 122 kcal | Starch | Starchy, must be cooked. |
| Fried Plantain Chips | 500+ kcal | Fat & Carbs | Highly processed, added oil. |
| Dried Banana Chips | 350+ kcal | Concentrated Sugar | Water removed, concentrating fructose. |
| Mashed Banana (1 cup) | 200 kcal | Carbs & Sugar | Increases density per volume. |
The Impact of Processing and Added Ingredients
While raw plantains have a higher natural calorie density than raw dessert bananas, processing methods lead to the most dramatic increases in calories.
- Dried Bananas and Chips: When water is removed from fruit through dehydration, the sugars become highly concentrated. Commercially prepared banana chips are often fried in oil and contain a huge amount of added fat, turning a healthy snack into a high-calorie indulgence.
- Mashed Bananas: While mashing a banana doesn't add calories, it does change the volume. A cup of mashed banana has more calories (approx. 200) than a cup of sliced banana (approx. 134) simply because more fruit is packed into the same space. It also changes the glycemic index, as the fruit's structure is broken down.
Factors to Consider When Comparing Banana Calories
- Variety: Plantains naturally have more calories per gram than dessert bananas. Other, less common varieties have slight differences.
- Preparation: Cooking with oil (frying) or dehydrating dramatically increases calories.
- Size: A larger banana of any type will have more total calories than a smaller one.
- Ripeness: Changes the type of carb (starch vs. sugar), but has a minor effect on total calories per weight.
Ultimately, if you're looking for the highest calorie banana, a fried plantain or dried banana chips will far surpass any raw variety due to added fats and concentrated sugars. For a natural, unprocessed banana, a larger-sized plantain is the most calorically dense choice. For those monitoring calorie intake, paying attention to the type, size, and especially how the banana is prepared is crucial.

Conclusion: It's All in the Preparation
The question of which banana has the highest calories is not as simple as picking a specific variety. While plantains naturally possess a higher calorie density than dessert bananas like the Cavendish, the most significant calorie increases are seen in processed forms. Frying adds large amounts of fat, and drying concentrates sugars, making both fried plantains and banana chips the highest-calorie options. For raw fruit, size is the most dominant factor for total calories, though plantains are denser per gram. For a healthy, lower-calorie option, sticking to a medium, raw dessert banana is your best bet, while cooked plantains and processed banana snacks should be consumed more sparingly.
What are the nutritional values of bananas?
Bananas are packed with important nutrients such as potassium, vitamin B6, and vitamin C. They provide a good source of carbohydrates and fiber.
What factors influence the calorie content of a banana?
Beyond variety, factors like size, ripeness, and preparation method (frying, drying) all influence the final calorie count.
How many bananas a day are healthy?
While there's no fixed rule, 1-2 bananas per day can be a healthy part of a balanced diet. It's important to vary your fruit intake for a broader range of nutrients.
