The applicability of the glycaemic index (GI) in the context of mixed meals and diets is still debatable. The objective of the present study was to investigate the predictability of measured GI in composite breakfast meals when calculated from table values, and to develop prediction equations using meal components. Furthermore, we aimed to study the relationship between GI and insulinaemic inde...

Since its inception in 1981, some members of the nutrition community have misunderstood the application of the glycaemic index (GI). It is disappointing that the study by Flint et al. (2004) in a recent issue of this journal adds further confusion. As originally conceived, Jenkins and colleagues saw the value of introducing a mechanism of comparing the glycaemic potential of carbohydrate exchan...

Brand-Miller and Wolever seem to have forgotten what they promised millions of readers in their popular books, The G.I. Factor and The Glucose Revolution (1st and 2nd editions), namely that: ‘Normally real meals consist of a variety of foods. We can still apply the G.I. factor to these real meals even though the G.I. values are originally derived from testing single foods in isolation.’ They ha...

A computer system, called SERVE-NZ Nutririon Management System, for use in diabetes management, addresses the problem of concurrently controlling postprandial glycaemic response and nutrient intake in meals containing a number of foods, is described. It converts the weight and relative glycaemic potency of each food to its content of glycaemic glucose equivalents (GGE) - the amount of glucose t...
