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 | 21 g | 12 | Medium |
| 100 g | 42 g | 24 | High |
| 60 g · 1 chapati | 25 g | 15 | Medium |
| 120 g · double serving | 50 g | 29 | High |
What the studies found
The value of 59 is the median of 18 published measurements in the International Tables of Glycemic Index (2021). Results range from 28 to 81. 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.
