GI Testing & Laboratories

The GI values of foods must be measured using valid scientific methods. It cannot be guessed by looking at the composition of the food. Currently, only a few nutrition research groups around the world provide a legitimate testing service.

The Glycemic Index Foundation recommends the following laboratories that test to the International Standard (ISO 26642:2010):

 

AUSTRALIA AND NEW ZEALAND

The University of Sydney’s Glycemic Index Research Service (SUGIRS) – Australia

Glycaemic Index Otago The University of Otago in New Zealand

 

ASIA
Temasek Polytechnic

Clinical Nutrition Research Centre

 

NORTH AMERICA

Glycemic Index Laboratories, Inc

Please contact the laboratories directly for costs, requirements and testing timelines as they operate independently of the Foundation.
