Glycemic Index and Glycemic Load:
Glycemic Index: A relative measure of how rapidly the digested carbohydrate appears in the blood as glucose relative to the same amount of pure glucose over time. A 50 g amount of glucose would have a GI of 100 while a 50g amount of other carbohydrate sources would be expressed relative to the glucose GI.
GI is 70 or more is high
GI of 56 to 69 is medium
GI of 55 or less is low.
