Nutritional Profile of a 100g Yellow Banana
Beyond the headline figure of 89 calories per 100 grams, a yellow banana offers a wealth of essential nutrients. These calories primarily come from carbohydrates, providing a quick and natural energy source. The fruit is also packed with vitamins, minerals, and dietary fiber, contributing to its reputation as a healthy and convenient snack.
Macronutrient Breakdown
For a standard 100g serving, the nutritional composition is a testament to the banana's simple yet effective energy delivery system:
- Carbohydrates: Approximately 22.8 grams, primarily from natural sugars like fructose, glucose, and sucrose.
- Dietary Fiber: About 2.6 grams, which is crucial for digestive health and helps promote feelings of fullness.
- Protein: Roughly 1.1 grams, a small but notable contribution.
- Fat: Negligible, typically less than 0.3 grams.
Key Vitamins and Minerals
Bananas are a powerhouse of essential micronutrients, with a 100g serving providing:
- Potassium: About 358mg, which is vital for heart health, muscle function, and maintaining fluid balance.
- Vitamin B6: A significant amount, which plays a role in metabolism, brain development, and immune function.
- Vitamin C: Offers antioxidant benefits that protect the body against free radical damage and support a healthy immune system.
- Magnesium: Contributes to blood pressure regulation, bone health, and nerve function.
The Impact of Ripeness on Banana Calories
The ripeness of a banana directly influences its carbohydrate composition and, consequently, its sugar content. This is a critical factor for anyone monitoring their blood sugar or managing weight. As a banana ripens, the starches convert into simple sugars.
Green (Unripe) vs. Yellow (Ripe) Bananas
- Green Bananas: Contain a higher proportion of resistant starch, a type of carbohydrate that is not easily digested in the small intestine. This acts more like soluble fiber, feeding beneficial gut bacteria and leading to a more gradual rise in blood sugar.
- Yellow Bananas: The familiar sweet, yellow banana has had most of its resistant starch converted to simple sugars. This makes it easier to digest and results in a quicker energy release. The overall calorie count per 100g remains very similar to a green banana, but the composition changes.
Comparison of Banana Calories to Other Common Fruits
To put the calorie count of a yellow banana into perspective, it's useful to compare it with other fruits based on a standard 100g serving. This helps in making informed dietary choices, especially for those who are calorie counting.
| Fruit (per 100g) | Approx. Calories | Key Nutritional Difference |
|---|---|---|
| Yellow Banana | 89 kcal | Higher in carbohydrates, fiber, and potassium. |
| Apple | 52 kcal | Lower in calories and carbohydrates, good source of fiber. |
| Orange | 47 kcal | Much lower in calories and higher in Vitamin C. |
| Grapes (red) | 89 kcal | Similar calorie count, but often higher in sugar and lower in fiber than bananas. |
| Strawberries | 32 kcal | Very low in calories, high in Vitamin C, and an excellent source of fiber. |
