"Cups" is a measurement of volume, or "how much cereal occupies this space?" Grams is a measurement of weight. Rice crispies, for example, are puffed rice.

Grape Nuts cereal has a moderate glycemic index (GI) value, typically around 50-60, which classifies it as having a low to moderate impact on blood sugar levels. While it's not the lowest GI option available, it is higher in fiber and protein compared to many other cereals, which can help stabilize blood sugar. For individuals monitoring their GI intake, it can still be a reasonable choice when consumed in moderation.
