Effects of the anthocyanin-rich juice and the anthocyanin-depleted placebo on antioxidative parameters before and after intervention. Study participants consumed 0.33 L of the anthocyanin-depleted placebo (P) and anthocyanin-rich juice (J) over 28 days. Before (0 d) and after (28 d) intervention, blood samples were drawn and 24 h-urine samples were collected. Enzyme activities of SOD (U/mL) (a), CAT (nmol/min/mL) (b), GPx (nmol/min/mL) (c) as well as TEAC (mmol/mL) (d) were measured in plasma (n = 35). TPC (mg GAE/24 h) (e) was measured in urine (n = 34). Upper panel: Heatmap analyses showed single values for each participant. Lower panel: Values are presented as aligned dot blot bars with median and interquartile range (25th–75th). Significant differences were calculated with a mixed model with multiple comparison test (Šídák’s) or ANOVA with multiple comparison test (Šídák’s). Values after intervention were different with * p < 0.05, ** p < 0.005 to corresponding controls. ns, non significant.
