Changes in the concentrations of acetic acid and lactic acid in plasma. Changes in postprandial acetic acid (A) and lactic acid (B) in plasma after the ingestion of the study meal supplemented with the placebo or polydextrose (PDX) presented as box plots and analyzed by a linear mixed-effects model. The decrease (11.9%) in the concentration of lactic acid after the consumption of PDX was statistically significant when compared to the placebo (P = 0.01). The curves are adjusted to zero by subtracting the median of all values at the first time point (0 min) from the parameter values presented in the box plots.
