How Glycemic Index Is Calculated?

The GI value of a food is determined by giving people a serving of the food that contains 50 grams of carbohydrate minus the fiber, then measuring the effect on their blood glucose levels over the next two hours.

How do you calculate low glycemic index?

To find the GL, divide 40 by 100 and multiply that by two to get a GL of 0.8. This GL score means these four strawberries have a low glycemic load, as the scoring is slightly different than that of GI: Low GL foods have a score of 10 or less. Moderate GL foods have a score between 11 and 19.

How does the glycemic index work?

The glycemic index (GI) assigns a numeric score to a food based on how drastically it makes your blood sugar rise. Foods are ranked on a scale of 0 to 100, with pure glucose (sugar) given a value of 100. The lower a food's glycemic index, the slower blood sugar rises after eating that food.
