Soluble fiber dextrin enhances the satiating power of beverages.
This study compared the effects of four types of fiber on satiety and energy intakes at the next meal using a standard double-blinded preload study design. Study participants (14 men and 22 women) each took part in 6 study sessions. Study preloads were a combination of a solid snack and a liquid beverage (energy range 0.78-0.83 MJ) containing four different types of fiber: soluble fiber dextrin (12 g), soluble corn fiber (11.8 g), polydextrose (11.8 g), and resistant starch (11.2g). All four fibers were compared to two control conditions of equal volume: an isoenergetic, low-fiber preload and a lower-energy, low-fiber preload. All preloads were presented twice for a total of 0.35-1.65 MJ and 1-24 g fiber. Satiety ratings were collected for 20 min intervals for 220 min during the morning testing session. A test meal was served at 1200 h and plate waste measured. The five higher-energy preloads led to higher fullness and lower hunger ratings compared to the low-energy control but were not significantly different from each other. Relative to the isoenergetic control, only soluble fiber dextrin significantly suppressed energy intakes (p=0.023). Supplementing beverages with soluble fiber dextrin affects short term energy intake and may have implications for weight control.
