Welcome to the official website of Glycemic Index University, the leading authority on the glycemic index (GI) and international GI database. Based in the prestigious Boden Institute of Obesity, Nutrition, Exercise and Eating Disorders and Charles Perkins Centre at the University of Sydney, our website is updated and maintained by our esteemed GI Group, comprised of renowned research scientists and dietitians, led by Professor Jennie Brand-Miller. With over 250 scientific publications, Professor Brand-Miller is a globally recognized authority on carbohydrates and the glycemic index.

The glycemic index is a ranking system of carbohydrates based on how they affect blood sugar levels. Our mission is to provide comprehensive information on the GI and promote its health benefits. Low GI carbohydrates, which produce smaller fluctuations in blood glucose and insulin levels, are crucial for long-term health, reducing the risk of type 2 diabetes, heart disease, and maintaining weight loss.

Our work is endorsed by major diabetes organizations worldwide, including the American Diabetes Association, Canadian Diabetes Association, and Diabetes UK. Additionally, the International Federation of Gynecology and Obstetrics recommends focusing on lower GI foods for gestational diabetes, while high-fiber, low GI diets have been proven to reduce cholesterol levels.

We follow the internationally recognized standard method for measuring the GI of foods, ensuring accuracy and reliability. To help consumers make informed choices, we have launched the GI Symbol Program, which guarantees that foods displaying the symbol have been properly tested by accredited laboratories.
