Yes, bananas have a low to medium glycemic index (GI), typically ranging from 42 to 58. This means they don’t cause a rapid spike in blood sugar levels compared to high-GI foods. However, the exact GI can vary based on the ripeness of the banana. Greener bananas have a lower GI as they contain more resistant starch, which converts to sugar as the banana ripens.
