Glycaemic indices of the under‐ripe and over‐ripe bananas differed (43 ± 10 and 74 ± 9: p < 0.01). Unripe green bananas have a typically lesser glycemic index than ripe yellow ones. However, in a lot of studies, the degree of ripeness is not specified, and glycemic index for bananas might range from 46-70, with 52 considered as the average. 13 The lower the glycemic “score,” so to speak, the slower those levels will rise.
