What Is the Glycemic Index?
The Glycemic Index (GI) ranks carbohydrate-containing foods from 0 to 100 based on how quickly they raise blood glucose after eating, compared with pure glucose (which is set at 100). A food with a high GI is digested and absorbed quickly, causing a fast, sharp rise in blood sugar. A food with a low GI is digested more slowly, producing a gentler, more gradual rise.
GI values are determined through lab testing on real human volunteers, using a fixed 50g-carbohydrate portion of the food — not a typical real-world serving size. That's the key difference between GI and Glycemic Load: GI tells you about the quality of a food's carbohydrates, while Glycemic Load factors in how much of it you actually eat.
Glycemic Index Classifications
Low GI: 55 or below · Medium GI: 56–69 · High GI: 70 or above.

Frequently Asked Questions
The Glycemic Index (GI) is a 0–100 ranking of how quickly a carbohydrate-containing food raises blood glucose, compared with pure glucose. It's measured on a fixed 50g-carbohydrate portion of that food, regardless of a typical serving size.
A Glycemic Index of 55 or below is considered low, 56 to 69 is medium, and 70 or above is high. These are the standard thresholds used across most published GI research.
No. Glycemic Index reflects only how fast a food's carbohydrates raise blood sugar, tested on a fixed portion. Glycemic Load adjusts that figure for your actual serving size, giving a more realistic picture of a real meal's effect on blood sugar.
Glycemic Index values come from lab testing on real human subjects, which is time-consuming and costly, so only a portion of all foods have been formally tested. Similar foods generally have similar GI values, which is how most databases estimate coverage.
Yes. Glycemic Index only measures blood sugar impact, not overall nutrition. A food can have a low GI while still being high in saturated fat, sodium, or added sugar, so it's best used alongside general nutrition guidance rather than in isolation.
