The Starch-to-Sugar Conversion
The ripening process involves the conversion of starches into sugars, making the banana sweeter and more easily digestible. This conversion affects the banana's calorie content and glycemic index.
Ripeness Stage | Calorie Content (approx.) | Sugar Content |
---|---|---|
Green | 80-90 calories | Low |
Yellow | 100-110 calories | Moderate |
Spotted/Brown | 120-130 calories | High |
