Interindividual comparability of blood glucose alterations after meals of complex carbohydrates.

Summary Young male and female probands underwent an DGTT (oral glucose tolerance test) using a glucose load of 1 g/kg b.wt. The alterations in blood glucose levels were checked and plotted by a Biostator. A week later groups of those probands were fed an isocaloric meal of complex CH, namely either potatoes, noodles or white bread. The resulting BG curves were also checked by a Biostator. It turned out that: 1. the shapes of the BG curves after glucose load were not interindividually comparable. 2. there was neither a similarity of the shapes of the BG curves within the groups after any of the different CH levels. 3. But if one compares the shape of the BG curves after glucose load and after a meal of any of the complex CH of one and the same person , there is a striking similarity in those curve shapes. The differences between them lie just in the mostly lower BG values of the curves after CH meals compared with those after glucose load. 4. Therefore the resulting graph of both of those curves is in all observed cases a straight line with a probability better than 0.001, called OGTT-calibrating resulting graph.
