What to know
Muffins averaged a low GI of 53 across 13 tests thanks to their fat, but a café-sized muffin can hold as much carbohydrate as four slices of bread, giving it a high glycemic load.
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 | 26 g | 14 | Medium |
| 100 g | 52 g | 28 | High |
| 60 g · 1 small muffin | 31 g | 17 | Medium |
| 120 g · double serving | 62 g | 33 | High |
