International Carbohydrate Quality Consortium & Consensus Statement


The International Carbohydrate Quality Consortium (ICQC) is a non-profit, worldwide organization of leading nutrition scientists from ten countries on three continents. All members and chairs are academic scientists and/or from non-profit organizations.  The mission of the ICQC is to support, summarize and disseminate the science around dietary carbohydrate and health with a focus on quality with the objective to harmonize the work of scientists from academia, industry and government.


Initial Concept

IQCQ was created on June 7 2013 in Stresa, Italy in response to scientific, governmental and public needs to have more clarity on the science around dietary carbohydrates and health. Scientific world experts in carbohydrate quality joined a two-day meeting held with the goal of summarising the evidence of the possible impact of carbohydrate quality including glycemic index (a measure of carbohydrate quality), glycemic load (a measure that combines carbohydrate quality and quantity in real-world portion sizes), and overall issues of glycemic response (how the body’s management of blood sugar is affected by both food and lifestyle, over time).

In May 2015, the Consortium published a Consensus paper stating  that “There is convincing evidence from a large body of research that low glycemic index/glycemic load (GI/GL) diets reduce the risk of type 2 diabetes and coronary heart disease, help control blood glucose in people with diabetes, and may also help with weight management.” The Consortium recommended inclusion of Glycemic Index and Glycemic Load in national dietary guidelines and food composition tables, and that packaging labels and symbols on low-GI foods should be considered. They also confirmed low GI measurements complement other ways of characterizing carbohydrate foods (such as fibre and whole grain content) and should be considered in the context of an overall healthy diet.
