Glycemic Index Calculator
You can read more about the calculator and about GI in the text below the form.
The glycemic index calculator helps you discover the GI value of foods, starting from fruits and vegetables to nuts and beverages.
The tool is helpful in the management of diabetes but also for health-conscious people who want to keep their sugar levels constant and avoid any spikes.
The glycemic index of foods is plotted on a scale from 0 to 100, depending on how they affect the blood glucose levels.
As a reference, pure glucose is plotted at 100.
High GI foods (above 70) increase blood sugar quickly and the body needs to mobilize extra resources to absorb them.
Low GI foods (below 55) take more time to be absorbed, therefore allow the body time to adapt.

About the tool
The glycemic index calculator offers information about the effect of food on blood sugar levels through the glycemic value of aliments from different categories: fruits, vegetables, legumes, nuts, grains, pasta, bread, bakery products, dairy, meals, sugar types, treats and beverages.
Once some foods are selected, the calculator will offer the GI value of each of them. For each category of foods, one item can be selected at a time.
The GI value offered refers to an average portion which for fruits and vegetables would be around 150 g, for other foods would be 100 g and for beverages, about 250 mL.
What is the glycemic index?
The GI is a scale that rates carbohydrate rich foods based on their effect on blood glucose levels. Pure glucose is taken as reference for the GI of 100.
Whilst foods with high GI increase blood glucose levels fast, those with low GI absorb glucose slower.
In the case of the first, the body is subjected to serious travail to absorb the glucose while in the case of the second, the body has time to adapt the regulatory measures to make use of the absorbed glucose.
The three categories of GI are:
■ Low GI: values below 55;
■ Medium GI: between 56 and 69;
■ High GI: values above 70.
The glycemic index of foods is most commonly used in the management of diabetes, however, health conscious people can use the calculations to keep their sugar levels constant.
During periods of increased mental and physical activity, high GI aliments can help the body meet the increased demands. However, their consumption should not become a habit.
