ObjectivesThis study assessed the safety and efficacy of a new beverage on suppressing hunger and improving feelings of satiety in healthy volunteers.MethodsIn the safety study, participants (n = 269) received either 1) a control beverage-coffee alone (group C); 2) the study beverage-coffee, whey protein, inulin, and dextrin (group S); or 3) an inulin-enriched beverage (I group). The study was held over a 7-d period during which participants were required to consume 2 cups of coffee a day.ResultsThere were no significant differences between the groups in any reported adverse effects, apart from more abdominal pain after the first cup in group I versus S (P < 0.05).ConclusionsThis study showed that a coffee beverage enriched with inulin, dextrin, and whey is safe and has possible benefits with regard to feelings of hunger and satiety 2 h after ingestion.
