What to know
Wheat tortillas and wraps tested low GI, probably because the fat in the dough slows digestion. Large burrito-size tortillas still carry a lot of carbohydrate, so size matters.
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 | 23 g | 11 | Medium |
| 100 g | 46 g | 23 | High |
