How it works
Each food's glycemic index, or GI, comes from the international tables: how much a serving's carbs raise blood sugar against pure glucose at 100, as a mean with its spread. Within 5 points counts as about the same. Low GI is 55 or less, high is 70 or more.
The bonus round uses glycemic load instead, which also counts how many carbs a serving holds. That's why a cup of white rice makes a bigger hill than a can of cola, with carbs from USDA FoodData Central.
The tables' own authors say GI shouldn't be used in isolation. Rice crackers raising blood sugar more than ice cream doesn't make ice cream the better snack.
