“…Our observation from clinical practice is that diabetic patients tend to receive conflicting messages from health educators regarding the advisability of consuming dates, with some suggesting restraint or even avoidance as a means to improve glycemic control. However, this appears to conflict with findings from previous studies demonstrating that dates have low to medium GIs [4,21-24]. We hypothesized that different types of commonly used dates would have low to medium GIs and therefore their consumption by diabetic subjects does not result in significant postprandial glucose excursions.…”

BackgroundThis study was designed to determine the glycemic indices of five commonly used varieties of dates in healthy subjects and their effects on postprandial glucose excursions in individuals with type 2 diabetes mellitus.MethodsComposition analysis was carried out for five types of dates (Tamer stage). The weights of the flesh of the dates equivalent to 50 g of available carbohydrates were calculated. The study subjects were thirteen healthy volunteers with a mean (± SD) age of 40.2 ± 6.7 years and ten participants with type 2 diabetes mellitus (controlled on lifestyle measures and/or metformin) with a mean HbA1c (± SD) of 6.6 ± (0.7%) and a mean age (± SD) of 40.8 ± 5.7 years. Each subject was tested on eight separate days with 50 g of glucose (on 3 occasions) and 50 g equivalent of available carbohydrates from the 5 varieties of date (each on one occasion). Capillary glucose was measured in the healthy subjects at 0, 15, 30, 45, 60, 90 and 120 min and for the diabetics at 0, 30, 60, 90, 120, 150 and 180 min. The glycemic indices were determined as ratios of the incremental areas under the response curves for the dates compared to glucose. Statistical analyses were performed using the Mann-Whitney U test and repeated measures analysis of variance.ResultsMean glycemic indices ± SEM of the dates for the healthy individuals were 54.0 ± 6.1, 53.5 ± 8.6, 46.3 ± 7.1, 49.1 ± 3.6 and 55.1 ± 7.7 for Fara'd, Lulu, Bo ma'an, Dabbas and Khalas, respectively. Corresponding values for those with type 2 diabetes were very similar (46.1 ± 6.2, 43.8 ± 7.7, 51.8 ± 6.9, 50.2 ± 3.9 and 53.0 ± 6.0). There were no statistically significant differences in the GIs between the control and the diabetic groups for the five types of dates, nor were there statistically significant differences among the dates' GIs (df = 4, F = 0.365, p = 0.83).ConclusionThe results show low glycemic indices for the five types of dates included in the study and that their consumption by diabetic individuals does not result in significant postprandial glucose excursions. These findings point to the potential benefits of dates for diabetic subjects when used in a healthy balanced diet.Trial Registration NumberClinicalTrials.gov NCT01307904

“…Currently, very limited, inconsistent, and contradictory information is available on the glycemic response, GI, and GL values of different date varieties, which could be attributed to both different food types and methodological variation. 20 – 23 A number of factors can affect the chemical composition of dates, including the agricultural methods used and soil conditions during cultivation, the ripening stage, and the cultivar. 24 Therefore, it is important to understand the GI and chemical composition of different local and regional date varieties.…”

BACKGROUNDDates are consumed worldwide, and are an important fruit for many individuals in Saudi Arabia. Currently, limited information is available on the glycemic indices of different date varieties.OBJECTIVESTo determine the glycemic index (GI), glycemic load (GL) and glycemic response for 17 common date varieties in Saudi Arabia.DESIGNProspective clinical trial on healthy subjects.SETTINGCollege of Medicine, Qassim University, Buraydah, Saudi Arabia.PATIENTS AND METHODSThe available carbohydrate content of Tamer stage dates was determined using standard laboratory methods. Healthy subjects (ten males and nine females) received 50 g of glucose (on three separate occasions) and 50 g equivalent of available carbohydrates from the seventeen varieties of date (each once). The GI and GL were then calculated.MAIN OUTCOME MEASURE(S)GI, GL, and glycemic response.RESULTSThe mean (SEM) GI of the date samples was 55.2 (7.7) (range, 42.8–74.6). Sellaj and Maktoomi exhibited the highest GI (74.6 [10.1] and 71.0 [11.1]), respectively, whereas Shaqra, Sukkary, and Sag’ai had the lowest GI (42.8 [5.5], 43.4 [4.7] and 44.6 [6]), respectively. The GL of the date samples ranged from 8.5 to 24. Sellaj had a high GL (24), whereas Ajwah and Shaqra had a low GL (8.5 and 9.2). The analyses suggested no significant difference in GI between the date varieties. However, the GL values differed significantly between the 17 date varieties (P<.001).CONCLUSIONThe results provide reliable GI and GL values for 17 common date varieties in Saudi Arabia. The identification of date varieties with lower glycemic responses may help lower the GI of the diet of both healthy and diabetic Saudi individuals.LIMITATIONSWe used dates at the Tamer stage, which may not be translatable to all types of dates.

“…Nevertheless, high consumption of date may bring about concerns of obesity and diabetes, especially diabetes mellitus, as date is recognized to be high in sugars (∼40–80%) with a glucose to fructose ratio of around 1.17 . However, date has been reported to have a low to medium glycaemic index (35.5–49.7) depending on the type of date . The low glycaemic index of date could partly be attributed to its relatively high concentration of fructose and dietary fibre .…”
