Abstract: The effects of resistant starch and dietary fiber on food intake, satiety and postprandial metabolic responses remain controversial. To assess the effect of a meal containing resistant starch on food intake, satiety, glucose and insulin responses. Twenty-two healthy subjects (13 male, 9 female; age 26±4 year; BMI 23.7±2.4 kg m¯2) undertook 5 study meals, taken in random order, consisting of cereal bars and beverages; control meal taken twice (0 g Resistant Starch (RS)) and three doses of RS (5, 10 and 25 g). Subjects rated their satiety level and symptoms and blood samples were collected prior to and at 15, 30, 45, 60, 90 and 120 min after consuming the study meals. Postprandial glucose and insulin levels were measured. Using the satiety ratings, the satiety quotient and appetite score were calculated. Two hours after eating, subjects were given an ad libitum meal and total energy intake was determined. There were no significant treatment differences in the incremental Area Under the Curve (iAUC) for glucose or insulin. However, at 90 and 120 min the incremental blood glucose and insulin levels after 25 g RS were significantly lower than that of the control (p = 0.004 and p = 0.001 for glucose, p = 0.043 and p = 0.042 for insulin, respectively). Feelings of fullness were greater with the 5 g dose of RS compared to the control, while the satiety quotient for overall appetite was significantly greater for 25 g RS in the early phase after the eating episode. The present study indicates that a meal containing RS may decrease postprandial glucose and insulin responses and enhance subjective feelings of satiety.
