Here is a cut and paste:

When a person consumes a meal, the digestive enzyme bile is released into the duodenum, the part of the intestinal tract where the majority of digestion takes place. This bile is used to break down any fatty foods that were eaten. However, we will release more bile than is necessary to break down all the fats and a fairly significant amount of bile will go unused. This bile will be recycled and returned to the liver, where the liver will return it to the gall bladder to be stored until the next meal. The next meal comes and again we have an excess over the need and bile will again be recycled. This pattern can continue to repeat for years.

Now enter into the scene soluble fiber. Soluble fiber binds tightly with bile in the intestinal tract, in fact, so tightly that the bile cannot be reabsorbed through the intestinal tract and return to the liver. Because fiber cannot pass the intestinal barrier, the bile that is bound with the soluble fiber will travel the length of the intestinal tract and be excreted from the body. Now, the liver recognizes that it has no recycled bile to send down to the gall bladder for the next meal. Therefore the liver will be forced to make bile (which it is very capable of doing). Bile is made out of cholesterol and the liver will pull cholesterol out of the blood stream to make this digestive enzyme. Subsequently, cholesterol levels will begin to fall.
