Example: Pumpkins have a glycemic index of 72 which makes them a high GI food, however, they only have 6 grams of carbohydrate per 100 gram serving, giving them a low glycemic load. You can eat pumpkin without having to worry about spikes in your blood sugar level. Using the calculation above, we get a glycemic load of (6 x 72) / 100 = 4.32 which is less than 10.
