c. ​soluble fiber converts dietary cholesterol into bile, which is recycled for use in the digestive process.
d. ​viscous fiber binds with bile in the intestine and is excreted in feces.
e. ​insoluble fiber converts to bile in the large intestine and binds with cholesterol

Answer 1

The answer is : d. viscous fiber binds with bile in the intestine and is excreted in feces.

There are two types of fiber: insoluble and soluble(also called viscous).

Viscous fiber absorbe in water and forms a gel-like consistency in the intestines. This fiber can bind to the bile, which helps break down fat molecules into smaller pieces, and consequently bind up harmful toxins, cholesterol, and fat that it contains. Eventually, the fiber together with the bile, cholesterol, toxins and fats will leave the body.
Less cholestrol will reduce heart diseases.
