Resumen
The gastrointestinal digestion of food and further gut microbial activity render a myriad of
different molecules that could be responsible for the biological activities that are classically assigned to
their parent compounds. This has been previously shown for some phytochemicals whose antioxidant
capacity was either increased or decreased after being metabolized by gut microbes. Whether a
global antioxidant capacity that is extracted from food is determined by the gut microbial community
structure is still not well described. In the present study, we in vitro digested and fermented 48
different foods that were submitted to different culinary treatments using the stools of lean children,
obese children, celiac children and children with an allergy to cow’s milk proteins. Their antioxidant
capacities were assessed with the DPPH and FRAP assays, and the percentage that each food
contributed to their daily antioxidant intake as well as their antioxidant capacity by portion size
was inferred. Overall, cereals, fruits and vegetables displayed a higher contribution to their daily
antioxidant intake, while tubers, fish and meat exhibited a higher antioxidant capacity by serving
size. The food that was fermented in the lean children’s and those children that were allergic to cow’s
milk protein’s fecal material, showed a higher antioxidant capacity, which could imply that there is a
larger role of the gut microbiota in this area.
