Does high fructose corn syrup have a high Glycemic Index?
The Glycemic Index (GI) is a ranking of foods, beverages
and ingredients based on their immediate
effect on blood glucose levels. The GI measures
how much blood sugar increases over a period of
two or three hours after a meal. Some scientists
believe that selecting foods with a low GI helps
in diabetes management.
Carbohydrate foods that break down quickly during
digestion have the highest GI. The benchmark in
many indexes is glucose, with a GI of 100. Compared
with glucose, the GI of fructose is very low with a
value of 20. Sucrose and honey, both with similar
compositions, have moderate GI values that range
from 55 to 60. (13) Although it has not yet been
specifically measured, high fructose corn syrup would be expected
to have a moderate GI because of its similarity
in composition to honey and sucrose.
It must be kept in mind that the body does not
respond to the GI of individual ingredients, but
rather to the GI of the entire meal. Since added sugars (principally sucrose and high fructose corn syrup) typically contribute less than 20 percent of calories, it is clear that high fructose corn syrup is a minor contributor
to the overall GI in a normal diet. (28) Home Top
