Abstract

Background/Objectives: The potential positive health effects of carob containing snacks are largely unknown. Therefore, two studies were conducted to 1.firstly determine the glycemic index (GI) of a carob-snack compared to chocolate cookie containing equal amounts of available carbohydrates and 2.compare the effects of a carob vs. chocolate cookie preload consumed as snack before a meal on (a) short-term satiety response measured by subsequent ad libitum meal intake, (b) subjective satiety as assessed by visual analogue scales (VAS), and (c) postprandial glycemic response. Subjects/ Methods: Ten healthy, normal-weight volunteers participated in GI investigation. Then, 50 healthy, normal-weight subjects consumed, cross-over, in random order, the preloads as snack, with one-week wash-out period. Ad-libitum meal (lunch and dessert) was offered. Capillary blood glucose samples were collected at baseline, 2h-after breakfast-and-just-before-preload consumption, 2h-after-preload, 3h-after-preload and-just-before-meal-(lunch-and-dessert),1h-after-meal and 2h-after-meal consumption. Results The carob snack was low and chocolate cookie high GI foods (40vs.78 on glucose scale). Consumption of the carob preload decreased the glycemic response to a following meal and subjects’ feeling of hunger, desire to eat, preoccupation with food, and thirst between snack and meal, as assessed with the use of VAS. Subsequently, subjects consumed less amount of food (g) and had lower total energy intake at meal. Conclusions: The carob snack led to increased satiety, lower energy intake at meal and decreased post-meal glycemic response possibly due to its low GI value. Identifying foods that promote satiety and decrease glycemic response without increasing the overall energy intake may offer advantages to body weight and glycemic control.
