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 g | 1 | Low |
| 100 g | 8 g | 3 | Low |
| 120 g · 1 medium fruit | 9.6 g | 3 | Low |
| 240 g · double serving | 19 g | 7 | Low |
What the studies found
The value of 35 is the median of 3 published measurements in the International Tables of Glycemic Index (2021). Results range from 28 to 76. 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.
