The glycemic load (GL) is a relatively new way to assess the impact of carbohydrate consumption that takes teh glycemic index into account, but gives a fuller picture than does the glycemic index (GI) alone.
A GI value tells you only how rapidly a particular carbohydrate turns into sugar. It doesn't tell you how much of a carbohydrate is in a serving of a particular food. You need to know both things to understand a food's effect on blood sugar.
That is where glycemic load comes in. The carbohydrate in watermelon, for example, has a high GI. But there isn't a lot of it in a serving so watermelon's glycemic load is relatively low.
High GL is 20 or more
Medium GL is 11 or 19 inclusive
Low GL is 10 or less
Madwoman Foods products labeled "Low Glycemic" are below 10 and normally below 5. Our pizzas and flatbread have a glycemic load of ZERO and our tea cakes have a glycemic load of 2 or 3 depending upon the flavor.
