Background In light of evidence demonstrating improvements in glycemic control with moderate fructose intake and low glycemic index fruits, our aim was to determine the glycemic and insulinemic indices and postprandial responses to raisins in an acute‐feed setting. Methods 10 healthy participants (4M, 6F) consumed breakfast study meals on four occasions over a 2–8wk period: Meal 1, white bread [WB] (108g WB; 50g available CHO) served as the control and was consumed on two separate occasions; Meal 2, Raisins [R50] (69g raisins; 50g available CHO); and Meal 3, Raisins [R20] (1 serving, 28g raisins; 20g available carbohydrate). Postprandial glucose and insulin was measured over a 2hr period for the determination of glycemic index (GI), glycemic load (GL) and insulin index (II). Results The raisin meals, R50 and R20, resulted in significantly reduced postprandial glucose and insulin responses when compared to WB (P<0.05). Furthermore, raisins were determined to be low GI, GL and II foods. Conclusions The favorable effect of raisins on postprandial glycemic response, their insulin‐sparing effect, low GI combined with their other metabolic benefits may indicate that raisins are a healthy choice not only for the general population but also for individuals with diabetes or insulin resistance.
