Red bananas nutrition is closer to a regular yellow banana than most websites suggest. The red skin is striking, and the flavour is sweeter, but the published nutrient data for red bananas is thin. This guide explains what the data actually says, why so many pages repeat the same numbers, and who needs to watch their potassium.
Quick Answer: Are Red Bananas More Nutritious?
Not in any way that has been well measured. USDA FoodData Central does not list red bananas separately, so the “red banana” figures you see online are almost always standard banana data: about 89 calories, 2.6 g fiber and 358 mg potassium per 100 g. Red cultivars may carry more carotenoids such as lutein, but no reliable data shows a meaningful difference in calories, potassium or vitamin C. People with kidney disease should treat red bananas as a high-potassium food.
What Are Red Bananas?
Red bananas are dessert bananas with reddish-purple skin. They belong to the AAA genome group of Musa, the same broad group as the familiar Cavendish. The fruit is usually shorter and chunkier than a Cavendish, with creamy white to pale pink flesh. You may see them sold as Red Dacca bananas.
Dole describes them as fragrant and creamy. They are harvested reddish-green and ripen during and after shipping. When ripe, the skin turns a deeper purple and the fruit gives slightly when pressed. In the US, UK, Canada and Australia, they are usually found in larger supermarkets and specialist grocers, and they often cost more than yellow bananas.
Red Bananas Nutrition Facts: What the Data Actually Shows
Here is the most important point on this page. USDA FoodData Central has no separate entry for red bananas. Dole confirms this on its own red banana page, noting that USDA does not distinguish banana varieties and that its figures come from Cavendish bananas.
So, the table below uses the two USDA records for raw banana. Treat these as the best available estimate for red bananas, not a direct measurement.
| Nutrient | Per 100 g (SR Legacy) | Medium banana, 118 g | %DV per 118 g | Per 100 g (Foundation Foods) |
|---|---|---|---|---|
| Calories | 89 | 105 | n/a | 97 |
| Carbohydrate | 22.8 g | 26.9 g | 10% | 23.0 g |
| Fiber | 2.6 g | 3.1 g | 11% | 1.7 g |
| Total sugars | 12.2 g | 14.4 g | n/a | not reported |
| Protein | 1.1 g | 1.3 g | 3% | 0.7 g |
| Fat | 0.3 g | 0.4 g | 1% | 0.3 g |
| Potassium | 358 mg | 422 mg | 9% | 326 mg |
| Vitamin C | 8.7 mg | 10.3 mg | 11% | 12.3 mg |
| Vitamin B6 | 0.37 mg | 0.43 mg | 25% | 0.21 mg |
| Magnesium | 27 mg | 32 mg | 8% | 28 mg |
| Folate | 20 mcg | 24 mcg | 6% | n/a |
Potassium in context
Bananas are known for potassium, yet one medium banana gives about 422 mg. Against the current 4,700 mg Daily Value, that is about 9%. Older pages often show 12%, because they used the previous 3,500 mg Daily Value. Bananas are a useful source, but they are not uniquely high.

Why Red Bananas Nutrition Figures Online Are Unreliable
Search for red banana nutrition and you will see the same set of numbers repeated: 90 calories, 21 g carbs, 1.3 g protein, 3 g fiber per 100 g. Those figures match the generic USDA banana record, rounded. In other words, they describe bananas in general, not red bananas specifically.
Copying errors make it worse. Some pages list red bananas at only 22 mg of potassium per 100 g. That figure is actually the phosphorus value, and it is off by more than 300 mg. Others quote vitamin B6 in micrograms when USDA reports milligrams, which understates it a thousandfold.
Even the two USDA banana records disagree. The older SR Legacy entry shows 2.6 g fiber and 358 mg potassium per 100 g. The newer Foundation Foods entry, based on fresh lab analysis of ripe bananas, shows 1.7 g fiber and 326 mg potassium. Ripeness, growing conditions and lab methods all shift the result. So, a spread of values is normal, and any page quoting a single precise figure for red bananas is guessing. Our guide to reading nutrition labels explains how these databases differ.
Do Red Bananas Have More Antioxidants?
Possibly, for certain carotenoids. In one published comparison of ten banana cultivars, the cultivar labelled Red Banana had the highest lutein of the group. However, its provitamin A content was far below that of Nendran, an orange-fleshed cooking banana. Lutein is a pigment found in the eye, but eating more of it from bananas has not been shown to prevent eye disease.
Much of the red colour sits in the peel, which you do not eat. Therefore, the skin colour is not a reliable guide to what the flesh contains.
Red Bananas Nutrition Claims: Where Each One Stands
| Claim | Where it stands | What this means for you |
|---|---|---|
| Red bananas provide potassium, fiber and vitamin B6 | Supported | True of bananas generally. One medium banana gives about 9% DV potassium and 25% DV vitamin B6. |
| Red bananas are healthier than yellow bananas | Not established | No reliable nutrient data compares the two directly. |
| Red bananas have a glycemic index of 10 | Not supported | The international GI tables give raw banana an average of 51. No validated red banana value was found. |
| Red bananas manage diabetes | Overstated | Bananas can fit a diabetes meal plan, counted as carbohydrate. They do not treat diabetes. |
| Red bananas prevent eye disease | Not supported | They may contain lutein, but no trial shows bananas prevent macular degeneration. |
| Red bananas boost fertility or testosterone | Not supported | No human evidence. Bananas are not a meaningful zinc source. |
| Red bananas cure hair loss or reverse wrinkles | Not supported | No food has been shown to do this. |
| Red bananas lower heart disease or cancer risk | Overstated | Diets rich in fruit are linked with better health, but no single fruit has been shown to lower these risks. |
Safety: Potassium, Kidney Disease and Diabetes
Kidney disease. The National Kidney Foundation lists half a banana as a higher-potassium food, defined as 200 mg or more per serving. People living with kidney disease can have trouble keeping blood potassium in a safe range. High blood potassium, called hyperkalemia, can affect heart rhythm. If you have kidney disease, follow the potassium limit your care team gives you, and count red bananas the same way as yellow ones.
Medicines. Some medicines change how your body handles potassium. If you take a prescription medicine for blood pressure, heart failure or kidney disease, ask your pharmacist whether you need to watch potassium-rich foods. Do not stop or change a medicine because of diet advice online.
Diabetes. A medium banana has about 27 g of carbohydrate. People with diabetes can include bananas by counting that carbohydrate within their plan. Riper bananas contain more sugar and less starch, so they may raise blood sugar more quickly.
Allergy. Banana allergy is uncommon but real, and it is sometimes linked with latex allergy. Seek urgent care for swelling of the lips, tongue or throat, or difficulty breathing.
How to Choose and Eat Red Bananas
- Choosing: Pick fruit that is slightly firm, with no cracks or bruises.
- Ripening: Leave them at room temperature until the skin deepens to purple and the fruit softens a little.
- Eating: Peel and eat as a snack, slice into yogurt or oats, or add to fruit salads and smoothies. Our tropical smoothie nutrition guide shows how fruit choices change sugar content.
- Cooking: They can be baked into banana bread or pancakes, just like yellow bananas.

Frequently Asked Questions About Red Bananas Nutrition
Red bananas taste sweet and creamy, and many people describe a slight berry note. The texture is often softer than a Cavendish banana.
Red bananas are ripe when the skin turns a deep purple and the fruit gives slightly when pressed. Ripen them at room temperature and avoid fruit with cracks or bruises.
No. USDA FoodData Central does not list red bananas separately. Most red banana figures online are standard banana data, about 89 calories and 358 mg potassium per 100 g.
There is no reliable evidence that they are. They may contain more of some carotenoids such as lutein, but calories, potassium and vitamin C appear broadly similar.
Using standard banana data, a medium 118 g banana has about 422 mg of potassium. That is about 9 percent of the 4,700 mg Daily Value.
Some can, in limited amounts, but bananas are a higher-potassium food. If you have kidney disease, follow the potassium limit set by your care team and count red bananas like yellow ones.
No validated glycemic index for red bananas was found. The international GI tables list raw banana at an average of 51. Riper bananas tend to raise blood sugar faster.
Yes, most people with diabetes can include bananas by counting the carbohydrate, about 27 g in a medium banana. They do not treat diabetes or replace medicine.
