Glycemic loadno datano data

The portion weights come from the USDA household measures for this food. Carb units = carbs of the portion ÷ 10, 12 or 15 g. Glycemic load = GI × carbs of the portion ÷ 100. Glycemic load needs a measured GI. This food has no measured GI, so the glycemic load row shows “no data”.

Glycemic index

No data

The 2021 international GI tables do not include this food. We do not show a GI estimate without a measurement.
