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. Bac303, Bacteroides-Prevotella; Erec482, Clostridium coccoides - Eubacterium rectale cluster; Rrec584, Roseburia genus, Clep866, Clostridium leptum cluster; Ato291, Atopobium cluster; Bif164, Bifidobacterium group; Prop853, clostridial cluster IX. Total bacteria were detected with the EUB338 probe.
