  1. All values are mean ± SEM. Baseline values are shown in Table 1. HCF, diet high in cereal fiber; HP, diet high in protein; MIX, diet moderately high in both cereal and protein. 1P values refer to the respective treatment × time interaction in the full model. 2Sum SCFA includes the measurement of fecal iso-acids
