The Glycemic Index Foundation (GIF) is an Australian not-for-profit health promotion charity owned by The University of Sydney and Diabetes NSW & ACT. The Glycemic Index Foundation is committed to providing the community with information and the tools required to improve its overall health through scientifically-backed low GI healthy eating principles.

The Glycemic Index Foundation is recognised internationally as a world leader in translating the science of glycemic index into practice for the benefit of consumers. At the heart of the Foundation is the GI Symbol program, a world-first low GI food labelling program designed to help consumers make healthier choices. The GI Symbol is a certified trademark which guarantees to consumers that a food has had its GI tested at an accredited laboratory and that the food is an all-round healthy choice, because it meets stringent nutrition criteria (consistent with international dietary guidelines).
