Abstract


The comparative effects of glucose and fructose on appetite and specifically on hormones regulating appetite remain controversial, and the role of different types of sugars has not been investigated broadly. The aim of this study was to estimate the effect of raisins, a dried fruit rich in fructose, fibers, and phenolics, on hormones involved in the postprandial response. Ten healthy normal-weight subjects received in a crossover design 74?g raisins or 50?g glucose as reference food. Glucose, insulin, and appetite hormones were measured at time 0 and 60, 120, and 180?min after consumption. Glucose and insulin peaked significantly at 60?min in both trials with no difference in two trials. Gastric inhibitory peptide peaked significantly at 60?min in both trials and was found lower in raisin compared to glucose at 60 and 120?min postprandially. Ghrelin was lower in raisin compared to glucose at 120 and at 180?min postingestion. Ghrelin/obestatin ratio was lower at 120?min in raisin compared to glucose. No differences were reported for glucagon-like peptide-1, apelin, and obestatin in either trial. Raisin consumption could be favorable in terms of regulating appetite compared to refined sugars or glucose-based products in normal-weight healthy subjects.
