The aim of this study was to determine the glycaemic indices (GIs), peak incremental indices (PI), and time of peak increment (TPI) of eight kinds of fruits and their relationship with the type and amount of simple sugars directly assayed in the fruits. Sixty‐one type 2 diabetic patients randomized into eight groups—one for each category of fruit—participated in the study. GIs consisted of the following: pears = 60 ± 4.9; apples = 63 ± 8.3; oranges = 68 ± 6.5; grapes = 70 ± 7.5; plums = 75 ± 8.4; peaches = 80 ± 7.4; apricots = 82 ± 9.1; bananas = 83 ± 8.5. The PI values (mmol l −1 ) were the following: grapes = 2.52 ± 0.26; apples = 3.13 ± 0.75; pears = 3.48 ± 0.55; oranges = 4.02 ± 0.42; peaches = 4.07 ± 0.38; apricots = 4.08 ± 0.47; plums = 4.2 ± 0.45; bananas = 4.45 ± 0.39. There was no statistical differences in GI, and PI, within the different fruits. TPI of grapes (43.3 ± 5.2 min), oranges (45 ± 5.6 min), and peaches (45 ± 5.6 min) were statistical different ( p < 0.01) in respect to apricots (81.4 ± 5.5 min). GIs were positively correlated with total glucose contained in the fruits ( p < 0.05) and with PI ( p < 0.0002); negatively with fructose both free ( p < 0.02) and total (sum of free and present in sucrose ( p < 0.05). On the basis of these findings, there is unlikely to be a difference of biological importance related to GI and PI of fruits, whereas the significance of TPI remains still to be evaluated.
