Glycaemic index as part of the diabetes prevention strategy

The study by Victoria Miller and colleagues1 in The Lancet Diabetes & Endocrinology adds to and extends the growing body of evidence of the importance of understanding the physiological effect of dietary carbohydrate on homeostatic systems as a driver for the risk of non-communicable diseases (NCDs); for example, prevention of type 2 diabetes. Miller and colleagues use the glycaemic index and glycaemic load as a measure of the postprandial effect of dietary carbohydrate on blood glucose and how this affects the development of type 2 diabetes in the PURE cohort.
