How much sugar does green bananas have?

Unripe, green bananas are low in sugar. They contain mostly resistant starch, a type of starch that is not digestible by the human body and contributes few calories.

As bananas ripen, the resistant starch is converted into sugars, such as sucrose, glucose, and fructose. The sugar content of a banana increases significantly as it ripens from green to yellow to brown.

Here are the approximate sugar content of bananas at different ripeness stages:

Green banana (unripe): 5-7 grams of sugar per 100 grams of banana.

Yellow banana (partially ripe): 12-15 grams of sugar per 100 grams of banana.

Brown banana (fully ripe): 18-20 grams of sugar per 100 grams of banana.

In general, green bananas are a better choice for individuals who are looking to limit their sugar intake or manage their blood sugar levels.
