Comparison of postprandial glycaemia in Asians and Caucasians

Abstract

To compare postprandial glycaemic responses between Asian and Caucasian subjects. Postprandial capillary blood glucose concentrations were measured as 2-h incremental areas-under-the-curve (iAUCs) following consumption of a glucose beverage and a breakfast cereal in 27 Asians and 73 Caucasians. The mean difference in iAUC was 29%(95%CI 10, 51) and 63%(95%CI 32, 102) higher in the Asian compared with the Caucasian group following the glucose beverage and cereal, respectively.The glycaemic index (GI) of the cereal was 77(95%CI 66, 90) in the Asian group and 61 (95% CI 55, 67) in the Caucasian group; the values were different (P = 0.01). The findings suggest that dietary recommendations for people with diabetes and those at risk of Type 2 diabetes may be more appropriate if based on research in the ethnic group for which they are intended.
