What
is Glycemic index?
Glycemic index (GI) is a system that ranking the
foods on how carbohydrate in foods may affects the levels of blood glucose. It
will measure how quickly or slowly the carbohydrate in the foods digested.
There are three categories of GI foods which are low GI, intermediate GI, and
high GI. Foods that are categories as low GI are foods that are slowly digested
and absorbed while food with high GI are foods quickly digested and absorbed.
This concept have been introduced by Dr. David
J. Jenkins around 1980-1981 in Toronto University. Eat more low GI food and less high
GI food.

Glycemic
load (GL) estimated the impacts of carbohydrates consumed on the blood glucose
level by taking account the quantity of the carbohydrates consumed. It can be calculated by multiplying the
amount of carbohydrate contained in a specified serving size of the food with
the GI value of that food, and then divided by 100.
