What is the GI Symbol?

Before 2001, people would have to rely on unreliable data on the Gi values of foods and do their own research to help decide which carbohydrate foods to eat.

The GI Symbol is your guarantee that the Gi value has been tested by an accredited laboratory and is accurate. Foods that carry the GI Symbol have been assessed against a range of strict nutrient criteria in line with International Dietary Guidelines making them among the healthiest choices in their category.

Why is the GI Symbol so important?

Whether consumers are looking to improve their general health, have sustained energy or help prevent or manage a specific health condition, a low GI diet can help them do just that.

The Foundation has commissioned extensive scientific reviews to substantiate general level health claims supporting the benefits of GI that meet the requirements set out by FSANZ Standard 1.2.7 – Nutrition, Health and Related Claims.

A general level health claim refers to a nutrient, substance or property of a food and its effect on a health function. It must not refer to a serious disease or biomarker of a serious disease.

Research has proven that a healthy low GI diet helps individuals with specific health conditions. People with diabetes (type 1 and type 2) manage their blood glucose levelsi, blood cholesterol levelsii and reduce insulin resistanceiii – which is important for reducing the risk of long term diabetes related complications. A recent Cochrane review found that low GI diets can help people with diabetes reduce their HbA1c by 0.5%. This will help decrease the risk of common diabetic complications by ~20%. 

Following a low GI diet can also assist with weight loss and importantly healthy weight maintenance. In fact, a low GI diet provides health benefits for everybody across all stages of life.

How does the GI Symbol help consumers better than existing package labels?

The eye-catching GI Symbol is a powerful tool for consumers to quickly and reliably make healthy food choices. Foods with the GI Symbol have been laboratory tested and also meet strict nutrient criteria in line with International Dietary Guidelines for kilojoules, saturated fat and salt that make them among the healthiest choices in their category. 

  • For the educated consumer, Low GI carves out a place in a clutter of messages.
  • The Low GI Symbol is now recognised as the most important label on food for people with Type 2 Diabetes
  • Nearly 2 in 3 of the general population indicate likely influence on product purchase as a result of endorsement by the Foundation.
  • 2 in 3 Australians, and almost 9 in 10 people living with Type 2 diabetes would seek out Low GI on pack

(AIFST Glycemic Index Report 2018)

What types of products can use the GI Symbol? Do some foods qualify more easily than others?

The Glycemic Index (GI) is a relative ranking of carbohydrate in foods according to how they affect blood glucose levels. Food products that contain the minimum amount of carbohydrates and that meet our strict nutrient criteria can be GI tested to be eligible to earn the GI Symbol.

Carbohydrates are one of the most important sources of energy for our bodies and are mainly found in plants (fruits, vegetables, grains & legumes) or in foods made from plant sources.

Carbohydrates take two forms namely starches (such as potatoes, cereals, bread, and pasta) and sugars such as table sugar (sucrose), milk sugar (lactose), and fruit sugar (fructose).

Check out the categories on our GI Symbol Products page.

How is the GI measure and tested in products?

GI values of foods must be measured using valid scientific methods. It cannot be guessed by looking at the composition of the food or the nutrition information panel on food packaging.

Following the international standard method, the GI value of a food is determined by feeding 10 or more healthy people a portion of the food containing 50 grams of digestible (available) carbohydrate and then measuring the effect on their blood glucose levels over the next two hours. For each person, the area under their two-hour blood glucose response (glucose AUC) for this food is then measured. On another occasion, the same 10 people consume an equal-carbohydrate portion of the sugar glucose (the reference food) and their two-hour blood glucose response is also measured. A GI value for the test food is then calculated for each person by dividing their glucose AUC for the test food by their glucose AUC for the reference food. The final GI value for the test food is the average GI value for the 10 people.

Foods with a high GI score contain rapidly digested carbohydrate, which produces a large rapid rise and fall in the level of blood glucose. In contrast, foods with a low GI score contain slowly digested carbohydrate, which produces a gradual, relatively low rise in the level of blood glucose.

What does it cost to use the GI Symbol on product packages?

There is no cost beyond an annual license fee. The license fee to certify your product is calculated on gross sales of your product and capped at a maximum fee making it affordable no matter what size company you are.

Is the GI Symbol part of a government program?

No. The Glycemic Index Foundation (GIF) is a not-for-profit health promotion charity supported by The University of Sydney and Diabetes NSW & ACT. GIF is committed to providing the community with information and tools to help improve their health through scientifically-backed low GI healthy eating principles.

Products certified with the GI Symbol meet nutrient criteria consistent with International Dietary Guidelines and are aligned with government front of pack labelling programs.

GIF is constantly working with government and regulatory agencies around the world to encourage GI food labelling laws as well as government-led health promotion programs communicating the benefits of low Gi foods and diets.

The International Diabetes Federation recommend Low GI foods for achieving optimal glycaemic levels in Type 2 Diabetes (International Diabetes Federation Clinical Guidelines)

How do you help consumers understand what the GI Symbol means?

The GI Foundation carries out ongoing communication activity to familiarise consumers with the benefits of a low Gi diet.

Our mission is to help people lead a healthier life through the adoption of evidence-based low GI eating principles for better health. Awareness of GI has grown from 28% when the Symbol was first launched with now over 77% of Australians aware of GI.

“The GI Symbol was identified as one of the most widely recognised food endorsement schemes” (CEO Choice Nick Stace; 2010)

A low Gi diet focuses on the quality of carbohydrates you eat. Good carbohydrates (or low Gi carbohydrates) are more slowly digested helping keep your blood sugars stable, whereas bad carbohydrates cause your blood glucose levels to peak and crash.
