- Brief summaryL-arabinose is a pentose which is naturally present in plants. L-arabinose is a sucrase inhibitor and thereby lowers glycaemic and insulinemic responses when consumed together with sucrose as a drink in young healthy subjects. Still, we donít know if this effect is also observed in subjects that are less able to regulate their glucose levels. Further, long term effects such as 24h or 48h glucose responses are scarce.The main objective is to determine the effect of drinking a solution of sucrose with arabinose on glycemic responses in prediabetic subjects. Secondary objectives are continuous glucose responses, appetite ratings, tolerance of the treatments, L-arabinose in the blood, and excretion of L-arabinose in urine. The study is a randomized double-blind cross-over study with a washout period of 5 days. Eighteen subjects between 55-80y old with increased risk of developing type II diabetes will be included. The drinks will be consumed in fasting state as a breakfast. Further, lemonades with or without arabinose will be provided to drink before every meal during 48h, when meanwhile continuous blood glucose is measured.
