Effect of SM consumption on luminal total and subphase cholesterol concentrations. Concentrations of total and subphase cholesterol are shown in panel A and B respectively. Cholesterol content was measured in total luminal content and the aqueous subphase which contains the solubilized cholesterol after ingesting a standardized meal. Open and closed circles represent cholesterol concentrations after a SM diet and control diet respectively. Data are presented as means ± SEM.
