摘要

The incidence of age-associated ailments has increased proportionately with the expansion of the aging demographic. This study aimed to evaluate the anti-aging potential of synbiotic pineapple beverage formulated with 100% pineapple juice, 1% inulin, and Lacticaseibacillus rhamnosus ATCC 53103 (10 log CFU) in Caenorhabditis elegans and D-galactose age-induced mice. The synbiotic juice-treated nematodes exhibited a 24.52% increase in their lifespan, accompanied by lower levels of reactive oxygen species and improved structural functions. In vivo studies demonstrated that synbiotic treatment positively influences age-induced mice’s cerebellar function and spatial memory. Additionally, the synbiotic beverage containing 8–10 log CFU of Lacticaseibacillus rhamnosus showed a protective effect against hippocampal neuron damage. The control group displayed a higher Firmicutes/Bacteroides (F/B) ratio, whereas the significantly lower F/B ratio in the diseased groups indicated a reversal of microbial imbalance caused by D-galactose exposure. Furthermore, the consumption of synbiotic beverage mitigated telomere shortening in aged mice. The results highlight the anti-aging effects of a pineapple beverage formulated with Lacticaseibacillus rhamnosus and inulin as a synbiotic intervention. This study suggests that dietary interventions incorporating prebiotics and probiotics may serve as promising strategy for combating age-related disorders and promoting healthy aging.
