Nutritional Profile
A medium-sized banana provides a wealth of essential nutrients: [4]
- Potassium: Approximately 422mg, crucial for heart health and regulating blood pressure.
- Vitamin B6: Provides about 25% of the Daily Value (DV), supporting energy metabolism and brain health.

- Vitamin C: About 10% of the DV, which helps support the immune system. [4, 5, 6, 7, 8, 9]
Ripeness and Health Benefits
The nutritional benefits of a banana shift as it matures:
- Green (Unripe): High in resistant starch and prebiotics, which are excellent for gut health and have a lower glycemic index.
- Yellow (Ripe): The starch converts into sugars (glucose, fructose, and sucrose), making them a quick energy source.
- Spotted (Very Ripe): Contains higher levels of antioxidants and is much easier to digest. [9, 10, 11, 12, 13]
