N2 - The present study evaluated the nutritional quality and glycemic index of three sun-dried date varieties (Khalas, Khsab and Fardh) grown in Oman. Significant (P<0.05) differences were observed in the proximate chemical composition, dietary fiber contents, various sugar fractions and energy value of these dates. The moisture, ash, crude protein, total fat, and nitrogen-free extract values ranged between 18.77 and 23.71 g/100 g date flesh, 1.12 and 1.55 g/100 g date flesh, 1.28 and 1.89 g/100 g date flesh, 1.14 and 2.37 g/100 g date flesh, and 68.53 and 75.37 g/100 g date flesh, respectively. The dietary fiber and total sugar contents ranged between 8.83 and 13.11 g/100 g and between 52.17 and 59.96 g/100 g, respectively. The glycemic index (GI) of different varieties of dates collected from various regions of Oman ranged between 47.6 and 57.7. Overall no significant (P<0.05) differences were observed in the GI values of different varieties of dates. The regional effects on the GI values of dates were also non-significant (P>0.05). An inverse correlation (r2) was observed between the fructose fraction and the GI value of dates.
