Glycemic load by portion size
GI stays the same whatever you eat, but glycemic load scales with the amount: eating twice as much doubles the effect on blood sugar.
| Amount | Available carbs | Glycemic load | |
|---|---|---|---|
| 50 g | 4.5 g | 1 | Low |
| 100 g | 8.9 g | 3 | Low |
| 120 g · 1 medium fruit | 11 g | 4 | Low |
| 240 g · double serving | 21 g | 7 | Low |
What the studies found
The value of 33 is the median of 7 published measurements in the International Tables of Glycemic Index (2021). Results range from 29 to 54. That spread is normal: GI changes with variety, ripeness, cooking and processing, and between labs.
Each dot is one study. Green dots followed the ISO 26642 standard method.
