    The liver makes bile. Bile flows through tube like structures,

    known as ducts, from the inside of the liver to the gallbladder

    to be stored and concentrated. When our foods we eat reach

    the small intestines, hormones are released that signal the

    gallbladder to contract and this forces the bile into the common

    bile duct to flow to the intestines to emulsify the fats we eat.

    This allows the fats (like cholesterol) to be absorbed through

    the small intestines into the blood that flows to the liver through

    the portal vein. If the patients doesn't take in enough cholesterol

    into the body...the liver will make it. Why? because the brain

    needs cholesterol and also it is used to make cell membranes.

    The cholesterol attaches to the HDL (lipoprotein) to be transported

    to the liver from any place in the body. The LDL (lipoprotein)

    is what transports it away from the liver into the vessels.

    High levels of LDL means a greater chance of the a blockage of

    an artery as cholesterol can collect on the vessels walls. That

    is why it is known as the "bad cholesterol".

    Oat soluble fiber or even flaxseed oil or barley is known to help lower

    the cholesterol levels in the body. This may help patients who

    are placed on a lower cholesterol diet. However, some people

    have hereditary reasons for having high cholesterol and will

    not benefit from the diet alone...they will need to take statin

    drugs.

    Quotes from this site:

    Soluble fiber constitutes a type of fiber able to absorb fluid, which results in the formation of a type of gel. The soluble fiber in this gel can bind with some fatty acids eaten at the same meal and prevent them from being absorbed, which results in lower blood cholesterol levels, especially LDL cholesterol levels, and a smoother elevation of your blood sugar levels after the meal.

    All I know id that one has a higher density (HDL, high density lipid, or fat)), and the other is Low density fat. The one that we have problems with is the High density - I believe - because it sticks against the vein walls, obstructing it. This criteria is debated as we speak, saying that "cholesterol is a protection of the area affected" and that is the reason why it being there.
