The Core Calorie Comparison
On a head-to-head, raw basis, the calorie comparison between plantains and bananas is relatively straightforward. However, the story becomes much more complex when you factor in how each fruit is typically prepared and consumed.
Raw Calories: The Initial Verdict
In a standard 100-gram serving of raw fruit, a plantain contains approximately 122 calories, while a banana contains about 89 calories. This difference is primarily due to plantains being denser and higher in starchy carbohydrates compared to the equivalent weight of a banana. So, if you are comparing two raw, peeled fruits of the same weight, the plantain will indeed be the more calorically dense option.
The Impact of Ripeness
Both bananas and plantains undergo a significant transformation as they ripen. Green, unripe fruits are high in resistant starch, a complex carbohydrate that digests slowly and has prebiotic effects beneficial for gut health. As the fruit ripens and turns yellow or brown, this resistant starch converts into simple sugars. While this changes the carbohydrate composition, it does not drastically alter the total calorie count of the fruit itself. For example, the calories in a green banana are comparable to a ripe, yellow banana of the same size, though the sugar content is much higher in the latter.
How Cooking Changes Everything
Perhaps the most crucial factor in the calorie comparison is the preparation method. Bananas are predominantly eaten raw, keeping their calorie count consistent. Plantains, however, are almost always cooked, and the cooking method has a profound impact on their nutritional profile.
- Frying: A common preparation for plantains, such as making tostones or maduros, involves frying in oil. This process causes the plantain to absorb a significant amount of fat, which dramatically increases the total calorie and fat content. For example, one cup of fried plantains can contain significantly more calories than a cup of raw ones.
- Boiling or Baking: Healthier cooking methods like boiling or baking a plantain will add minimal calories, keeping the dish's nutritional value closer to its raw state. A cup of boiled green plantains is much lower in calories than a fried version.
Beyond Calories: A Look at Macronutrients
While calories offer a simple metric, a deeper nutritional comparison reveals more about how these fruits affect your body.
Starch vs. Sugar
The primary difference in their carbohydrate makeup is the ratio of starch to sugar. Plantains, especially when unripe, are very starchy, with a lower sugar content than bananas. This makes them more similar to a starchy vegetable like a potato. Conversely, bananas, especially when ripe, have a higher sugar content, which is why they are so much sweeter. This difference also affects their Glycemic Index (GI), a measure of how quickly a food raises blood sugar. Plantains tend to have a lower GI than bananas, which can be beneficial for blood sugar management.
Fiber Content
Both fruits are a good source of fiber, which is important for digestive health. As with carbs, ripeness plays a role. Green plantains and bananas, with their high resistant starch content, are particularly rich in fiber-like components that act as prebiotics to support beneficial gut bacteria.
Key Vitamins and Minerals
Both fruits are excellent sources of several vital nutrients, but with some key differences.
- Potassium: Both are famed for their potassium content, which is crucial for heart health and blood pressure regulation. Some research suggests plantains may contain slightly more potassium per serving than bananas.
- Vitamin C: Plantains often contain more vitamin C than bananas, which is a powerful antioxidant that supports immune function.
- Vitamin A: Plantains are a significantly richer source of Vitamin A, particularly vital for vision and immune health.
- Vitamin B6 and Magnesium: Both fruits provide these nutrients, important for brain function, metabolism, and bone health.

Which Should You Choose for Your Diet?
Choosing between a banana and a plantain depends heavily on your dietary goals and how you intend to eat them. If you're seeking a quick, low-calorie, and convenient snack, a raw banana is the clear winner. Its natural sweetness makes it perfect for smoothies, desserts, or a pre-workout energy boost.
If you're looking for a starchy, savory addition to a meal that offers sustained energy and a lower glycemic impact, a boiled or baked plantain is an excellent choice. However, if you are monitoring your calorie or fat intake, you should be mindful of preparations like frying, which can significantly increase the total calories. For weight management, focusing on portion control and opting for non-fried preparations is advisable for either fruit. Ultimately, both are nutritious and can be part of a healthy, balanced diet.
Conclusion
To answer the question, "what has more calories, a plantain or a banana?", the raw plantain is the more calorically dense of the two per 100 grams. However, this is not the whole story. The significant difference in how these two fruits are typically prepared and consumed is the most important factor for overall calorie intake. While a raw banana is a lighter, sweeter snack, a cooked plantain, especially when fried, can be substantially higher in calories. Both fruits offer unique nutritional benefits, and the best choice depends on your specific dietary needs and cooking preferences.
