Effect of diet intervention on the metabolites in the colon. (A) The contents of short-chain fatty acids (SCFAs). (B) The differentially expressed metabolites between LPG and CTG. (C) The differentially expressed metabolites between CG and LPG. (D) The differentially expressed metabolites between SPG and LPG. (E) The relative content of L-valine. (F) The relative content of L-isoleucine. (G) The relative content of L-phenylalanine. (H) The relative content of L-tryptophan. (I) Bobble plot of LPG to CTG. (J) The bobble plot of CG to LPG. (K) The bobble plot of SPG to LPG. Data are presented as mean ± SEM. Different letters indicate statistical differences among groups (p < 0.05). CTG, control group; LPG, low protein group; CG, casein group; SPG, soy protein group.
