Risks and Warnings
Foods that have a glycemic index of 55 and higher must be consumed in moderation. On the other hand, those that have a glycemic index that’s below 50 are acceptable.
Ripe bananas that have brown specks have a glycemic index of 48 to 51. As rule of thumb, the riper the banana, the higher its glycemic index or sugar content. Half a banana contains about 15 grams of sugar and therefore, it has relatively low impact on your blood sugar level.
The only time where diabetes patients should avoid bananas is when it is added in a dessert containing other sugar that can spike your glucose level. And just like with other fruits, you should consume bananas in moderation. Too much bananas can impact your blood sugar levels and can be bad for your kidneys too.
