Achtergrond van het onderzoek
L-arabinose is a pentose which is naturally present in plants. L-arabinose can act as a sugar substitute in many foods, among which drinks and cereal clusters.
The main objective is to determine and compare the effect of partly substituting sucrose by L-arabinose in a sucrose solution and in a cereal cluster on glycaemic responses and insulinemic responses in healthy humans. Secondary objectives are: To determine and compare the effect of partly substituting sucrose by L-arabinose in a sucrose solution and in a cereal cluster on: 1) the absorption and excretion of L-arabinose. 2) plasma GLP-1 concentration. 3) subsequent ad libitum energy intake. 4) appetite feelings. 5) the acceptability of the treatments as measured by gastro-intestinal comfort.
The study is a randomized within blocks, cross-over study. The liquids treatment is open labelled, for the cereal clusters the study is double-blind. All subjects will receive six interventions in an order randomized within solutions and cereal clusters. The food products will be consumed in fasting state as a breakfast. All control products contain 50g available carbohydrates. In the drinks, one treatment 30% (i.e. 15g) of the sucrose will be replaced by L-arabinose, the other treatment 15g L-arabinose without sucrose will be added to water; in the cereal clusters 10% and 15% sucrose will be replaced by L-arabinose.
Eighteen healthy adults between 18-35y old will be included.
The food products will be consumed in fasting state as a breakfast. All control products contain 50g available carbohydrates.
Doel van het onderzoek
Consumption of foods containing L-arabinose will improve glycaemic and insulinemic response.
