The Medical Advisory Board, Senior Staff, and Associate Research Fellows of the Glycemic Research Institute® provide Independent Pro Bono Certification for products that pass the strict criteria for “Low Glycemic” foods, by authorization of the United States government, the Canadian government and the United Kingdom government.

The Federal Glycemic Research Institute® Certification Marks and Seals of Approval are based on ongoing Human In Vivo Clinical Trials that determine the glycemic index, glycemic load, diabetic response, Lipoprotein Lipase, and adipose tissue fat-storing properties of foods, beverages, Nutraceuticals, and Pharmaceuticals. Determining how humans and animals metabolize foods allows scientists to gain insights as to the varying effects different foods have on metabolism and longevity.

Federal authorization for the Glycemic Research Institute Certification Marks can be seen at the Official United States, Canada, and UK government websites.

Defining GRI Low Glycemic
& Diabetic-Friendly Pet Foods

As a species, dogs are cats are evolutionarily designed to utilize animal proteins and fat as their primary fuel, with Low Glycemic fruits and vegetables as a secondary fuel. It is important to include Low Glycemic species-friendly fruits and vegetables in canine and feline pet foods.

Protocols for Analyzing & Testing Pet Foods

The following methodologies are utilized in determining the Glycemic and Diabetic properties of pet foods. Following HPLC/U-HPLC analysis, the data is cross-analyzed with Glycemic Research Institute (GRI) records of known glycemic indices of raw materials, and assigned a glycemic and diabetic index.
