EFFECT OF CONSUMPTION PATTERN OF YEMENI DATES ON GLYCEMIC INDEX AND GLYCEMIC LOAD

Date consumption is deeply rooted in Yemeni culture, yet its effect on glycemic response remains underexplored. This quasi-experimental study examined the impact of portion size and Basmala recitation on the Glycemic Index (GI) and Glycemic Load (GL) of Yemeni Sagai dates in 12 healthy adults. Participants consumed 2–6 dates, with or without Basmala, and postprandial glucose was measured at 0, 30, 60, 90, and 120 minutes. GI and GL were calculated using incremental area under the curve (iAUC) values with a 50 g glucose reference. Results revealed a non-linear relationship between portion size and GI, with smaller portions (2–3 dates) producing unexpectedly high or moderate GI values, while larger portions did not always increase glycemic response proportionally. GL analysis showed moderate values for 2–3 dates and high values for 4–6 dates, highlighting the importance of portion control. Consumption with Basmala significantly reduced GI (63.3 vs. 78.4) and GL (39.9 vs. 49.4) compared to no recitation (P < 0.05), suggesting that mindful or spiritual practices may influence glucose metabolism. These findings align with Islamic teachings advocating moderate, odd-numbered consumption of dates with Basmala and emphasize a holistic approach integrating cultural, spiritual, and nutritional guidance.
