We investigated the contribution of bile salts and glutathione (GSH) to the generation of bile flow in young, mature, and old female Sprague-Dawley rats, either fed ad libitum (AL) or subjected to a 40% dietary restriction (DR), which was supplemented or not with vitamins and minerals, starting from weaning. An age-related decline in bile flow was observed in the AL group. DR increased bile flow compared to age-matched AL rats, resulting in a twofold increase in the old animals. This was associated with a statistically significantly higher biliary GSH secretion rate and a moderate increase in the bile salt secretory rate. The apparent GSH-dependent flow was significantly increased in DR groups of all ages. Hepatic GSH concentration was closely related to the GSH secretion rate. These results indicate that the increase in biliary GSH content produced by DR is the major mediator of the increased bile flow, resulting in enhanced GSH and GSH-derived thiols supply to the intestinal lumen.
