Protein oxidative damage measured as plasma advanced oxidation protein product (AOPP) concentrations of volunteers during the study. Volunteers consumed one WGPF-burger daily between weeks 0 and 4 (intervention period), followed by a washout period (weeks 4 to 8), and then consumed one control-burger daily between weeks 8 and 12 (control period). Bars represent the mean value for each time; lines represent the 95% confidence interval. Analysis of variance (ANOVA) of the four repeated measures with the repeated contrast method was used to evaluate changes between the 4-week intervention periods over time.
