Selection and Storage

On selecting bananas, you need to look for its firm and bright appearance with intact stems and tips. It should be free from bruises or cuts. When a banana starts ripening, the starch content in the green bananas gets converted to easily digestible sugars like glucose and fructose. The banana peel turns yellow in color.

Diabetes patients and insulin resistant individuals are not advised to take ripe bananas due to its easily digestible sugar components.

Plan on when to buy bananas only based on when you want to add the fruit to your daily diet. Unripe bananas need to be kept at room temperature to accelerate ripening process. Ripe bananas can be refrigerated if you plan to eat the fruit in two or three days’ time. Refrigerated bananas should be brought back to room temperature before consumption.
