In middle-aged and older adults, we will analyze the gut microbiota and assess health-related outcomes, including body composition, physical function, depressive symptoms, and sleep status, to evaluate the effects of consuming a sweetener containing the prebiotics 1-kestose and inulin.
Efficacy
Participants in the prebiotic group will consume 17 g of an oligosaccharide-containing sweetener (3.4 g of 1-kestose and 8.5 g of inulin; 33 kcal) once daily with breakfast, while those in the placebo group will consume 10 g of maltose (33 kcal) once daily with breakfast. The intervention will continue for 8 weeks.
All participants will also be instructed to perform a prescribed 15-minute exercise program, consisting of stretching,calisthenics, amd aerobic exercises every day.
Before and after the intervention, body composition and physical function will be assessed, and questionnaires will be administered to evaluate depressive symptoms, sleep status, dietary habits, and exercise habits.
To assess genetic predisposition, polymorphisms in the beta-3 adrenergic receptor gene (ADRB3), which is involved in lipolysis; the uncoupling protein 3 gene (UCP3), which is associated with energy metabolism; and the mechanistic target of rapamycin gene (MTOR, formerly FRAP1), which is involved in muscle protein synthesis, will be analyzed. These genetic factors will be examined to explore interindividual differences in the effects of prebiotic supplementation on body composition.
