For a long time it was thought that any cholesterol in the blood – is evil, give rise to the appearance of cholesterol plaques on the walls of blood vessels and as a result, the development of a number of serious diseases. “In fashion” were even bezholesterinovye diet.
However, after a certain time, the scientists were able to establish the presence in the blood as “bad” or “good” cholesterol. And it turned out that for the treatment and prevention of various diseases little to reduce the amount of “bad” cholesterol in the blood, it is also necessary to maintain a “good” at the proper level.
Thus, we consider in more detail.
“Good” cholesterol are considered alpha-high density lipoprotein (HDL) cholesterol. This type of cholesterol wonderful job of excretion of cholesterol, the “bad”. Thus it protects our body against atherosclerosis and possibly obesity. In addition, HDL independently excreted from the body through the liver and intestines.
“Bad” cholesterol is an inert, non-functional cholesterol, including beta-lipoproteins of low and very low density lipoprotein (LDL and VLDL). In fact, this excess cholesterol, is not involved in the vital processes and the remainder in the form of plaques on the walls of blood vessels and arteries. He, unfortunately, is not excreted from the body itself, but merely collects them.
For the normal functioning of the body is very important to “good” and “bad” cholesterol were in some kind of balance with each other. Calculate this balance is very simple: total cholesterol divided by the number of “good” cholesterol. If the resulting number is less than six, you worry too early and you have everything is normal. If the number was greater than six, you should pass the relevant tests. At the same time, remember that a low content of cholesterol in the blood is as bad as high.
