FIGURE 3.

Differentiation of dairy products and serum samples of healthy men after milk or yogurt intake through the use of untargeted LC-MS metabolomics. OPLS-DA scores plot derived from (A) milk and yogurt samples, (B) postprandial serum after milk and yogurt intake (800 g), and (C) fasting serum after 2 wk of daily intake (400 g/d) of milk or yogurt. OPLS-DA, orthogonal projections to latent structures discriminant analysis; Q2, predictive ability parameter; R2Y, goodness-of-fit parameter; t[1], OPLS-DA predictive component; to[1], OPLS-DA orthogonal component.
