Description
Summary:White rice is a high glycemic index food, and therefore different approaches are adopted to reduce its glycemic effect. The present study investigated the effect of adding fenugreek and Nigella sativa seed powder to white rice on glycemia, appetite, palatability, and gastrointestinal clinical manifestations in healthy subjects. In a randomized crossover design, 16 healthy subjects consumed white rice alone (control group), white rice with 2-g fenugreek seed powder or white rice with 4-g nigella seed powder on different occasions. Each test meal provided 50 g of available carbohydrates. Blood glucose, subjective appetite, and gastrointestinal manifestations were measured at fasting and postprandially for 2 h. Palatability of the test meals was also measured using a 9-point hedonic scale. The nigella meal resulted in significantly lower blood glucose concentration (31.25 mg/dL) at 30 min (p = 0.022), compared to the control meal (43.88 mg/dL) whereas fenugreek meal showed no significant effect. Moreover, the nigella meal significantly increased satiety ratings at 30 and 90 min (p = 0.035 and 0.018, respectively). The results demonstrated that the addition of nigella powder to white rice reduced its glycemic response and increased satiety, compared to the control meal. All test meals were judged as acceptable by the subjects and their consumption didn’t cause any gastrointestinal discomfort. Results of the current study demonstrated promising implications for reducing glycemic response of white rice, a commonly consumed high-glycemic index food.
