Cholesterol is lipid, which chemically belongs to the sterols. It is an essential component of the membranes of all cells. The body consists of many cell types, but principally by liver cells. It is the raw material for the synthesis of all sexual hormones, both the man and woman, hormones, and of bile acids and bile salts from the liver. In blood circulation, mainly as a component of lipoproteins.
Interest on the amount of cholesterol in the blood: Because the amount of cholesterol in the blood correlated positively for several years now, with atherosclerotic lesions of arteries, i.e. arteriosclerosis. It turned out that that the larger the amount of cholesterol in the blood, the greater the risk for the occurrence of arteriosclerosis at an earlier age.
Arteriosclerosis: It is an unhealthy situation in which the stromal through the arteries fattened, so the pipe narrows the artery, hindering the flow of blood through the vessel. The narrowing of the lumen due to the new plaques in the artery through jacket. The plaques consist of a set of substances called atheroma, which consist of low density lipoproteins (LDL), degenerate smooth muscle, fibrous connective tissue, sums platelets, cholesterol, and in some cases and calcium salts.
In the plaque favors the coagulation of blood that clot formation, which can cause immediate and complete blockage of the artery, or can be detached and whole or split, and swept away and block other blood vessels, which cause embolism in the kidneys, intestines, the heart muscle, brain, etc. Cholesterol blood obtained from: 1. Primarily, this composed of liver cells. 2) The cholesterol we take in our food. 3) Large percentage of the neutral fats we take in our food and converted to cholesterol.
Well, the cholesterol in the blood increases when we eat a lot of neutral fat, even when these fats are saturated type, such as butter, milk, and fat from lamb, goat, beef or pork. Instead, the various vegetable fats (vegetable oils, which contain many unsaturated fatty acids) and fish oil from fish, appears to limit, but a small extent, the amount of cholesterol in the blood.
As if things are but, even when not taking any cholesterol ready with our food, and when reduced to the minimum amount of fat in our food configured to produce excess cholesterol, the cholesterol level Our blood will continue to be high, with all the unpleasant consequences mentioned above.
Most blood cholesterol recycled relatively rapidly between the liver, bile and small intestine and liver. That is, the liver uses cholesterol to bile salts composing. These are secreted in bile and are channeled to the small intestine. There are used to emulsify the lipid diet, thereby contributing digestion and absorption. But together with the lipids absorbed the bulk of bile salts, which returns back to the liver, and then to bile.
In this way, the bile salts secreted from the liver to the small intestine, only a very small part is lost in the feces from the body, so the liver does not need to synthesize all the time large amounts of bile salts.
However, retention in the intestine more bile salts, and the subsequent expulsion of feces, can have beneficial effects, and this can be done through regular dietary intake of large amounts of fiber, so that the volume content bowel is kept high. Within these large volumes of trapped and excreted in the feces, larger amounts of bile salts, i.e. substances that are composed of raw material cholesterol.
