Sterol balance data obtained from mice fed the different diets for 12 weeks. Feces were collected at three time points during the feeding trial and neutral sterol and bile acids content was measured by gas chromatography-mass spectrometry A: Daily fecal neutral sterol output. B: Daily fecal bile acids output. C: Daily sterol balance measured by subtracting fecal neutral sterol and bile acids output from cholesterol intake. Symbols: black diamonds, control diet; grey squares, Western diet. Data are presented as mean ± SEM (n = 5). ** p < 0.01; *** p < 0.001, NS: not significant.
