▸ glycaemic index n.

1981D. J. A. Jenkins et al. in Amer. Jrnl. Clin. Nutrition 34 363/1 The area under the 2-h glucose curve was expressed as a percentage of the appropriate mean GTT [= glucose tolerance test] value. This value was defined as the ‘*glycemic index’. 1983Science 15 July 214/1 The flatter the postprandial blood glucose response to a particular food relative to pure glucose, the lower the glycemic index. 1994Vogue Jan. 102/1 The worst carbohydrate is maltose, found in beer; its glycemic index is 110. 2002New Scientist 18 Mar. 31/2 Although gram for gram grapes contain more glucose than a soft drink, they have a much lower glycaemic index, because you digest them far more slowly. |
