Is Sustain still low GI? - Mike, Sandstone, Queensland

Hi Mike, we do not test the GI of Sustain anymore, so have removed the “Low GI” claim from front of pack. We no longer test for this as the Glycaemic Index of a product can change over time because it is determined by a number of complex factors. For example, any minor variations to the processing procedure or even the climate or geography of the grains used can impact a products GI.
If you’d like more information on GI, we recommend speaking to your GP or an accredited practicing dietitian.
