A PCA score plots (B: R2X = 0.641, Q2 = 0.522), PLS-DA score plots (C: R2X = 0.843, R2Y = 0.757, Q2 = 0.608), PLS-DA validation plots (D, permutation number: 200), OPLS-DA score plots (E: D + ND vs ND, R2X = 0.885, R2Y = 0.929, Q2 = 0.909; G: D + MS vs D + ND, R2X = 0.802, R2Y = 0.828, Q2 = 0.775), and OPLS-DA validation plots (F: D + ND vs ND, permutation number: 200; H: D + MS vs D + ND, permutation number: 200) according to the 1H-NMR spectra of metabolites in the plasma obtained from the ND (green circles), HFD (red circles), and MRD (yellow circles) group mice (n = 10). ND: saline + normal diet; D + ND: D-Gal + normal diet; D + MS: D-Gal + Met supplementation.
