It is a scale from 0-100 that ranks digested carbohydrates by how much they raise blood glucose levels compared to a reference food (glucose). www.EatGoodCarbs.com

 High GI carbohydrates or “gushers”  quickly digested  produce rapid release (“gush”) of after-meal glucose  GI values: 70+  Low GI carbohydrates or “tricklers”  slowly digested  produce slow gradual release (“trickle”) of after-meal glucose  GI values: 0 - 55 www.EatGoodCarbs.com

A measurement of how high a blood glucose level will rise after eating a specific amount of a specific carbohydrate. It combines the quality of the carbohydrate and the quantity of the carbohydrate portion into one number. www.EatGoodCarbs.com

GL = carbohydrate (grams/serving) x GI 100 Example #1: GL of a small apple 13 grams x 38 ÷ 100 = 5 grams Example #2: GL of a large apple 26 grams x 38 ÷ 100 = 10 grams www.EatGoodCarbs.com

GL tells us how much insulin the body needs to release into the blood stream to deal with the increased blood glucose level resulting from the digestion of a specific amount of a specific carbohydrate. www.EatGoodCarbs.com

 Individual food portion Low 0-10 Moderate 11-19 High 20+  Whole day Low < 80 Moderate 80 - 120 High > 120 www.EatGoodCarbs.com

 Glycemic Index: ranks carbohydrates based on their immediate blood glucose response. GI = carbohydrate quality  Glycemic Load: helps predict a blood glucose response to a specific amount of a specific carbohydrate. GL = carbohydrate quality + carbohydrate quantity www.EatGoodCarbs.com
