Serving Size ⓘ Serving sizes are taken from FDA's Reference Amounts Customarily Consumed (RACCs)
1 cup, sliced (150 grams)
Acidity (Based on PRAL) ⓘ PRAL (Potential renal acid load) is calculated using a formula.On PRAL scale the higher the positive value, the more is the acidifying effect on the body. The lower negative value is the more alkaline the effect is. 0 is neutral.
-6.9 (alkaline)
76% Potassium

Banana Glycemic index (GI)


By investigating scientific studies we found out different means for bananas Glycemic Index. Let’s discuss the most trustworthy ones.

According to the Glycemic index(GI) data of Harvard medical school (1) banana has low GI 51 ± 3.

Based on study (2) factors such as the size, texture, viscosity (internal friction or ‘thickness’) and ripeness of a food affect its GI. For instance, although both ripe and unripe bananas have a low GI (less than 55), an unripe banana may have a GI of 30, while a ripe banana has a GI of 51.

All the above you can easily find on International table of glycemic index and glycemic load values 2002 (3). There are published 10 different GI values for bananas, and the mean calculates GIs listed underneath the data. Besides, we can notice from the table, that there are some values higher than low GI. These inconsistencies also caused by some reasons like a methodological factors, different test methods of different laboratories etc.

Also another research compared the varieties of Banana (4).This research shows significantly higher GI values for banana overall with the highest Njalipoovan GI record, and none of them has low GI.

Banana Glycemic index various sorts

Thus, to sum up all the data, we decided to choose 52 for bananas GI as an average.
