description

Abstract This study evaluates the impact of two plant sterol (PS) enriched fruit beverages (0.6 g /100 ml), without (MfB) or with GOS (MfB-G) (1.2 g/100 ml) on the resistance against oxidative stress induced by non-conventional (cholesterol oxidation products (COPs)) and conventional (H2O2) oxidant compounds, as well as their impact on C. elegans longevity. Nematodes fed with both beverages (0.005–0.25%, v/v) showed similar improved oxidative stress resistance against COPs and H2O2. This effect was dependent on daf-16 transcription factor, although GOS showed an additional beneficial effect independent to daf-16. In addition, both beverages extended nematode lifespan, independently of the presence of GOS. Longevity assays using daf-16 and daf-2 mutant strains revealed that the observed effect was potentially linked to the insulin-IGF-1 pathway. These results provide new in vivo evidence for the potential use of PS enriched fruit beverages in the prevention of oxidative stress underlying many diseases.
