Abstract
Banana peels, often discarded as waste, represent one of the most abundant food by-products, highlighting the need for effective waste management and resource recycling strategies. Due to their rich nutritional content, banana peels have been investigated for various health benefits, including anti-obesity effects. In this study, we examined the potential anti-aging properties of banana peel extracts (BPEs) in Drosophila melanogaster. Our findings demonstrated that flies fed with BPEs exhibited an extended lifespan and a significant improvement in age-related decline in climbing ability. Additionally, Dilp2 mRNA expression level is markedly decreased in aged flies fed with BPEs. These results suggest that BPEs may serve as a potential anti-aging agent by enhancing locomotor function and extending lifespan, potentially through the modulation of insulin signaling in D. melanogaster.
