Polyphenols and Human Gut Microbiome Interactions: Role of in Ameliorating Inflammation

Plasma biomarkers and measures of inflammation: Nrf2/ NF-κB activation in monocytes will be analyzed.

Inflammatory cytokines (Interleukin-6 (IL-6), High Sensitivity C-Reactive Protein (hs-CRP), Tumor Necrosis Factor-α (TNF-α)) will be measured.

Analysis of GLP-2 will be done in plasma samples before and after chronic exposure to the study foods.

The concentration of calprotectin, zonulin, and IgA in fecal samples will be determined by enzyme-linked immunosorbent assay (ELISA) before and after chronic exposure to study foods.

Bile acids in plasma and fecal samples will be determined using UHPLC-QQQ-MS.

Polyphenolic metabolites (anthocyanin, ellagitannins and other phenolic components) will be identified and quantified in urine and plasma.Metabolites in samples will be identified and quantified using an Agilent 6550 iFunnel UHPLC-QTOF-MS and 6460 UHPLC-QQQ-MS, respectively.
