What is cholesterol
In millions of people in Britain, cholesterol is too high. However, many sufferers are not familiar with the term, therefore we would like to enlighten you in this article and dispel some lies. Cholesterol is a fat-like substance that is vital to humans, because it fulfills important functions throughout the body.
The main functions
- Structure of the cell membrane
- Crucial component in many metabolic processes of the brain
- Important starting material for the production of bile acids for fat digestion
- Is necessary for the formation of vitamin D
- Meaningful for the formation of certain hormones such as estrogen, testosterone and cortisol, which acts as a stress hormone, and is essential for many bodily functions.
What many people do not realize is that most of it is produced by the body itself. The daily required amount of cholesterol is 0.5 – 1 g. It can be produced by up to 90% by the body itself, which means that three-quarters itself is produced in the liver. In contrast, only a quarter of the total is absorbed by diet.
Good and bad
So that cholesterol can be transported in the blood, the fat-like and thus water-insoluble substance (a so-called lipid) combines with water-soluble proteins. The lipoproteins formed thereby, fulfill various functions in the body, which can be seen in the following table:
The classification of it into different types, depends on the content of lipids and proteins:
- Bad : Very Low Density (VLDL) – the precursor of LDL
- Bad : Low-Density (LDL)
- Good : High-Density Lipoproteins (HDL)
Bad refers to the cholesterol species with a high lipid content, ( high fat content), consisting of triglycerides and phospholipids. The good in this case is the VLDL. The higher the lipid content in it , the lower the density, and the more harmful the cholesterol is to people.
However, there is another subdivision:
- LDL is divided into 7 sub-units:
- LDL 1 and 2 are harmless sub-units that do not lead to arteriosclerosis.
- However, LDL 3 – 7 can be dangerous. In this case, cholesterol-lowering drugs, also called statins should be taken.
What happens to cholesterol in the body?
The cholesterol that enters the blood from the liver reaches the various body cells in the form of so-called fat-protein compounds, or lipoproteins. This binds to the receptors of the cell membrane and penetrates into the cell. Excess cholesterol, which is in the bloodstream, then is picked up by the liver.
As the number of receptors in the liver decreases, it absorbs less leaving cholesterol in the blood and leading to sequelae such as arteriosclerosis.
The total lipid content consists of triglycerides and phospholipids.
It is composed as follows:
- VLDL 85%
- LDL 75%
- HDL 50%
Therefore, VLDL and LDL are particularly unhealthy for the body. Only a good ratio between the total values of LDL and HDL, has a favorable effect on the level. In addition, the HDL is able to absorb the excess cholesterol back into the liver after ingestion.
The consequences of high cholesterol
The extent or consequences of adverse cholesterol levels are individually different, and can only be determined as part of a comprehensive blood test and a complete physical examination, especially of the blood vessels, because everyone’s body is different. For one person the value means high cholesterol and for another, the same value means a normal level. It also depends very much on the health of the vessels. You can have a high cholesterol but healthy blood vessels, then you still have no problem.
In general, consequences of a high cholesterol level are:
Deposits in the vessel walls
- Arteriosclerosis (atherosclerosis)
- Heart attack
- Fatty liver
How to treat
The so-called statins are a group of drugs that lower cholesterol. They inhibit an enzyme in the human body called HMG-CoA reductase, and are thus termed HMG-CoA reductase inhibitors or inhibitors. The term cholesterol synthesis enzyme inhibitor or CSE inhibitor is also used in this context. Statins are prescription drugs. When the enzyme is blocked by the lowering agent, less is produced in the cells, with the result that it is increasingly absorbed through the diet. As a result, the overall cholesterol level decreases and LDL is lowered. These drugs also increase the HDL level and thus excess cholesterol is transported back to the liver. The most prescribed cholesterol-lowering drugs are: Simvastatin- Order Simvastatin online now, with prescription and shipping!

Lower cholesterol with diet
Although lowering the level without medication is somewhat controversial since there is no immediate link, the following measures are recommended for protection from cardiovascular diseases: do not smoke, eat less saturated fats, move a lot, lose weight. The following foods are said to lower cholesterol and generally have a healthy effect. These include: artichoke extracts, fish oil, garlic, Indian myrrh, policosanol (a sugar cane extract), red rice flour, soy, walnuts, soluble fiber products, such as psyllium husks, and green tea extracts (catechin extracts). Generally, a combination of a balanced diet and exercise have a positive effect on overall health and thus on cardiovascular health.
