Explain which type of fiber prevents constipation and which type prevents high blood cholesterol
What will be an ideal response?
Soluble fiber (oatmeal) dissolves in water, binds bile and takes excess cholesterol out of the body. The liver then takes cholesterol from the blood to make more bile, thus lowering blood cholesterol levels. Insoluble fiber (bran) does not dissolve in water but it increases the bulk and weight of the stool, stimulating peristalsis, which speeds up the movement of feces through the large intestine.
