What to know
French baguette is one of the highest-GI breads: its light, open crumb is digested very quickly. Pair it with olive oil, cheese or salad rather than eating it on its own.
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 | 25 g | 19 | Medium |
| 100 g | 50 g | 38 | High |
| 30 g · 1 slice | 15 g | 11 | Medium |
| 60 g · double serving | 30 g | 23 | High |
What the studies found
The value of 76 is the median of 10 published measurements in the International Tables of Glycemic Index (2021). Results range from 57 to 95. 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.
