Accuracy
Glycemic index charts often give only one value per food, but variations are possible due to variety, ripeness, cooking methods, processing, and the length of storage. Potatoes are a notable example, ranging from moderate to very high GI even within the same variety.
The glycemic response is different from one person to another, and even in the same person from day to day, depending on blood glucose levels, insulin resistance, and other factors.
Most of the values on the glycemic index do not show the impact on glucose levels after two hours. Some diabetics may have elevated levels after four hours.

Famous quotes containing the word accuracy:
“Such is the never-failing beauty and accuracy of language, the most perfect art in the world; the chisel of a thousand years retouches it.”
—Henry David Thoreau (1817–1862)
“U.S. international and security policy ... has as its primary goal the preservation of what we might call “the Fifth Freedom,” understood crudely but with a fair degree of accuracy as the freedom to rob, to exploit and to dominate, to undertake any course of action to ensure that existing privilege is protected and advanced.”
—Noam Chomsky (b. 1928)
“In everything from athletic ability to popularity to looks, brains, and clothes, children rank themselves against others. At this age [7 and 8], children can tell you with amazing accuracy who has the coolest clothes, who tells the biggest lies, who is the best reader, who runs the fastest, and who is the most popular boy in the third grade.”
—Stanley I. Greenspan (20th century)
