Achtergrond van het onderzoek
L-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. However, when L-arabinose is consumed in solid form or in a mixed meal, no glycaemic lowering was observed. The main objective is to determine the disturbing effects of the macornutrients fat and starch, which are more often found in solid food products, on the reducing glycemic and insulinemic responses of L-arabinose after ingestion of a combined L-arabinose-sucrose drink with or without these macronutrients. Secondary objectives are appetite ratings, subsequent ad libitum energy intake, tolerance of the treatments, gastro-entero endocrine markers, L-arabinose in the blood, and excretion of L-arabinose in urine.
The study is a randomized within blocks, cross-over study. Within the three blocks sucrose, starch and fat, the study is double-blind.
All subjects will receive six interventions in a randomized order. Twentyfour healthy adults between 18-35y old will be included. The food products will be consumed in fasting state as a breakfast. All products contain 50g available carbohydrates.
