AB The prevalence of obesity has been increasing in children over the last few decades,becoming a concern for health professionals and governments. Gut microbial community structurein obese people have been found to differ from that of lean subjects for some taxa which couldresult in different production of microbial metabolites. The aim of the present work was to studywhether the gut microbiota from obese children extracts a different concentration of antioxidantcapacity than the gut microbiota from lean children. For this purpose, different foods were in vitrodigested and in vitro fermented using fecal material from obese and lean children. FRAP, DPPH andFolin-Ciocalteu methods were used to measure the antioxidant capacity released during digestionand fermentation. Overall, when using lean gut microbiota, antioxidant capacity released was higherwhen measured via DPPH and FRAP. Moreover, according to DPPH results, lean gut microbiotacould potentially release more antioxidant power from vegetables than from animal products, whileobese gut microbiota did the opposite. On the contrary, with the FRAP method obese gut microbiotareleased higher levels of antioxidant power from plant products than from animal products, butthe final antioxidant capacity was still lower than that released by lean gut microbiota. Therefore,these results reflect that the total antioxidant capacity of foods is influenced by the gut microbiota,although whether that antioxidant capacity is released from plant or animal products can be slightlyinfluenced by the method used for analysis.
