Figure 2. Typical 600 MHz ¹H NMR spectra of plasma metabolites obtained from the (A) control, (B) pea fiber, and (C) wheat bran fiber groups.

The region of δ6.0–9.0 was magnified 24 times compared with corresponding region of δ0.5–6.0 for the purpose of clarity. Metabolite keys are given in Table 1.
