The Glycemic Index Foundation (GIF)
We are a not-for profit health promotion charity formed in 2001 by The University of Sydney and Diabetes NSW.
Our mission is to translate over 30 years of science about the Glycemic Index into practice for the benefit of the whole community. More.

What is the Glycemic Index?
Carbohydrate is an essential part of our diets, but not all carbohydrate foods are equal. The Glycemic Index (GI) is a relative ranking of carbohydrate in foods according to how they affect blood glucose levels. Carbohydrates with a low GI value (55 or less) are more slowly digested, absorbed and metabolised and cause a lower and slower rise in blood glucose and, therefore usually, insulin levels. More.

What is Glycemic Load?
Glycemic Load (GL) is a measure of both the quality (the GI value) and quantity (grams per serve) of a carbohydrate in a meal. A food’s glycemic load is determined by multiplying its glycemic index by the amount of carbohydrate the food contains in each serve and dividing by 100. More.

Why choose low GI?
Low GI foods, unlike high GI, will not cause your blood glucose levels to spike and crash, meaning you get sustained energy from the foods you eat. Following a low GI diet is easy. It is not a restrictive diet, does not cut out major food groups and is a healthy and sustainable way of eating and suitable for the whole family. Click here to get started!

What is the GI Symbol?
The GI Symbol is your trusted guide to healthier food choices. Foods that carry the GI Symbol have had their glycemic index tested at an accredited laboratory and they must also meet strict nutrient criteria for kilojoules, saturated fat and sodium, and where appropriate, fibre and calcium. The nutrient criteria are consistent with international dietary guidelines and were developed in consultation with experts from the University of Sydney and Australian consumer diabetes organisations.

Added sugars and the GI Symbol Program
The GI Symbol Program includes category specific nutrient criteria that incorporate energy (kilojoules), total carbohydrate, total and saturated fat, sodium, and in certain categories dietary fibre and calcium. The energy and carbohydrate caps and dietary fibre requirements limit the amount of sugars that can be added to foods.Learn more about sugars and GI click here.
