Understanding a Banana Serving Size in Grams
When tracking nutritional intake, knowing the precise serving size is important. A medium banana, typically 7 to 7-7/8 inches long, is widely considered a single serving. This size usually weighs around 118 grams, excluding the peel.
Factors Influencing Banana Weight and Nutrients
Banana weight and nutritional content, including calories and carbohydrates, are affected by size and ripeness. As a banana ripens, resistant starch changes into simple sugars, increasing sweetness and the glycemic index. The form of the banana also matters; a cup of sliced banana has a different weight and nutritional value than a cup of mashed banana.
Comparing Different Banana Serving Sizes
Different banana sizes have varying weights and nutritional values:
| Banana Size | Length | Approximate Weight (g) | Approximate Calories | Approximate Carbohydrates (g) |
|---|---|---|---|---|
| Extra Small | < 6 inches | 81 | 72 | 19 |
| Small | 6–6 7/8 inches | 101 | 90 | 23 |
| Medium | 7–7 7/8 inches | 118 | 105 | 27 |
| Large | 8–8 7/8 inches | 136 | 121 | 31 |
| Extra Large | > 9 inches | 152 | 135 | 35 |
This table shows how size impacts weight and nutrients, which is useful when following recipes or tracking intake.
