What is Cholesterol?

Cholesterol itself is not a dirty word, although it is often immediately associated with something negative, because in reality this type of lipid important functions in the body. For example, it is a very important component of the plasma membranes of animal cells and precursor-natural processes that give rise to other cells of several important elements, including the vitamin D , sex hormones and bile salts.

Now the word cholesterol usually has a negative connotation because when used generally to refer to do low-density lipoprotein (LDL). Lipoproteins are actually responsible for cholesterol reaches the cells through the bloodstream. When there is an excess of low-density lipoprotein (LDL) cholesterol can accumulate in the arteries hindering the passage of oxygen through the blood, which does increase risk of heart problems and strokes. Hence, low-density lipoprotein (LDL) are known as bad cholesterol.

In addition to LDL are high density lipoprotein (HDL) which are those lipoproteins that carry cholesterol from the tissues of the body to the hígado.Debido to HDL can remove cholesterol from arteries and transport it back to the liver for excretion They are known as good cholesterol or lipoprotein good.

Good cholesterol, guard your heart

As we mentioned in previous articles, there are two types of cholesterol known as good cholesterol, HDL , and is called bad cholesterol, LDL. Both coexist in our body, but is highly recommended that the level of HDL is greater, for that compensates for the existence of the other negative.

And is that HDL removes the bad blood and ideally its level was 60 mg / dl or more. LDL cholesterol, in turn, clogs our arteries and makes us prone to heart attacks. The amount that we must maintain as the latter are DE100 mg / dl or less, and if you suffer from heart muscle that level should not exceed 70 mg / dl.

By the way, to see how you walk the two types of cholesterol-fulfillment but do not have a blood test.

We refer to a new study published in The New England Journal of Medicine, conducted in Australia and which has lasted 5 years, which is based on data obtained through an international level research which involved 9,770 patients with heart and aged between 50 and 60 years

During the test time these patients were given Lipitor to lower your LDL cholesterol (Lipitor is the most prescribed medicine in the world to reduce cholesterol).

It turned out that those who had more of HDL were least had heart failure, regardless of the outcome in terms of LDL. This led to the conclusion that the higher the HDL level less likely to suffer heart attacks have, even though the numbers of LDL or bad cholesterol, are very low, ie below 70 mg / dl.

Of course it also took into account other factors such as age, sex, muscle mass, whether they were smokers, or had diabetes, so that it is certain that there was no other factors which might affect the result of the sample.

It is therefore important to achieve and maintain a level high HDL levels high. This is important to exercise regularly, managing stress, eating a healthy diet and alcohol consumption is moderate This always under strict medical supervision. This is very good advice to follow to effectively prevent heart problems.
