The Human body-a complex mechanism, capable of self-regulation. So he created his nature, and laid each ingredient is vital for proper operation. Cholesterol – is an important component of each of our cells. In nervous tissue it very much, the brain is 60% fat. Also thanks to the cholesterol formed many of the hormones. Some associate the word cholesterol (cholesterol) atherosclerosis with something harmful. But let's see in detail, how it happens.

cholesterol is

Cholesterol and cholesterol. Is there a difference?

What is the cholesterol and cholesterol? Is there a difference between the terms, what role the body plays a connection? Physically – a liquid crystal. From the standpoint of chemical classification, the correct name for the compound with cholesterol, so that it sounded in the scientific literature. The particle -ol indicates that the compound belongs to alcohols. In Russia, doctors often use the term “cholesterol”.

From the Outside to cholesterol there's no need for the connection is 80 % produced by the body itself. The remaining 20 % comes with food, and this proportion is also necessary. The function of cholesterol in the body is very important, and replace that connection is simply impossible.

Cholesterol-is the substance included in the composition of stones formed in the bile ducts and gall bladder. Here it is the main component. The greater part of the stone is cholesterol, the higher the probability that to get rid of the calculus is possible without surgery. Stones are freely floating and have small dimensions.

The Synthesis of cholesterol in our body per day approximately is 0.5-0.8 Of them in the liver is formed of 50% in the intestines approximately 15 %. Each cell of an organism capable of synthesizing cholesterol. With food a day in the norm comes 0,4 g of the substance.

Role of cholesterol

Cholesterol in the blood – a compound that plays an important role in the synthesis of steroids, vitamin D, sex hormones, adrenal. It is an integral part of every cell membrane. Due to the cholesterol cells are able to keep their structure. Cell transport channels are formed also with the participation of this substance. Thus, if the body has a lack of cholesterol, the cells of worse function. There is a failure in their work.

An Important component of bile are the bile acids, they are also synthesized from cholesterol. To process this takes up a large part of the total cholesterol in the body - about three quarters. Bile acids for digestion is very important, all the metabolic processes depend on them.

 elevated cholesterol

“Good” cholesterol

Cholesterol-a substance that cannot dissolve in the blood plasma. The chemical composition of it, the impact on the body throughout the 20th century has been studied very intensively. In this field made a lot of discoveries awarded thirteen Nobel prizes.

Studies have shown that body there this substance in its pure form. He always has three elements, each plays a role. Since cholesterol cannot dissolve, to move around the body it requires auxiliary proteins transportable. In this form of the connection of cholesterol and protein, or lipoproteins. There are three classes of lipoproteins: low, very low and high density.

High density Lipoproteins are easily dissolved and leave no residue. Such a transport connection straight direct cholesterol processing in the liver, where it is formed from bile acids necessary for digestion. Then his remains arrive in the intestine. And then excreted. This kind of connection in medicine called “good cholesterol”.

“Bad” cholesterol

total cholesterol

Cholesterol is LDL (low density lipoprotein) was the term “bad cholesterol”. This type is the main transport form. Thanks LDL compound is delivered to the cells of the body. Such lipoproteins are poorly soluble and tend to form precipitation. If the level of LDL increases the risk of atherosclerosis.

The Remaining lipoproteins were not included in the first two groups belong to the lipoproteins of very low density. They are produced in the liver and carry cholesterol to all the cells of organs. Such compounds are most dangerous, they are forming atherosclerotic plaques.

Balance

All researchers say that the higher the blood levels of high-density lipoproteins, the better. But how to define the boundary, when useful connections can turn into bad? To control the total cholesterol (the total amount of bad and good), as well as the level of lipoproteins of different density, it is necessary to undergo a medical examination and hand over the biochemical analysis of blood.

So you will always know what level of cholesterol in your body. So time to take action and rectify the situation, if there are any deviations from the norm.

Cholesterol: normal

cholesterol in the blood

These Rules depend on the state of health, age and gender of the person taking the blood test. Common indicators are:

1. The normtotal cholesterol in an adult is 3.9-5.2 mmol/L. If the result from 5.2 to 6.5 , the doctors reported minor deviations from the norm. When increased from 6.6 to 7.8 – a moderate deviation. Above 7,8 – form of severe hypercholesterolemia, here already it is necessary treatment of disease.

2. Considering separately men it is worth noting that the level of this substance shall not exceed of 7.17 mmol/l, the limit for women – of 7.77. If cholesterol is elevated, then the doctor should give additional advice. In this case you need to pay attention to their health.

3. The ratio of high density lipoproteins to low-density lipoproteins should not exceed 1:3. These rules everyone should know.

If the values of total cholesterol and the ratio of “good” and “bad” you have everything in order, you do not need to blame his poor state of health cholesterol. If this level is exceeded slightly, it is easy to fix with proper nutrition, physical activity. Eliminate bad habits, play sports, look at the world with optimistic eyes, eliminate stress from your life and health back to normal.

Atherosclerosis and cholesterol

The reasons for the appearance of atherosclerosis a see cholesterol. If the total cholesterol is elevated, then he, putting off the vessel walls obstructs the blood flow. But we should remember that the reason “bad” cholesterol or LDL and very low density. “Good”, on the contrary, it cleans the blood vessels.

It has been proved that the relationship of atherosclerosis and cholesterol is very ambiguous. There is no doubt that if the cholesterol is elevated, then it is a risk factor for the development of atherosclerosis. But this pathology often develops in people who have normal levels of the considered connection. In fact, high cholesterol – is only one of many risk factors for the development of the disease. They also include Smoking, obesity, hypertension and diabetes. The presence of these factors even with normal cholesterol levels also leads to the development of atherosclerosis.

 cholesterol LDL

Different perspective

On the issue of cholesterol, there are different views. “Repair” material – cholesterol – accumulates in places where there is microdamages vessels, it blocks the damage, thus playing the role of healer. So often atherosclerosis is observed when the normal cholesterol level.

With the increased rate problem is much faster, besides the violation of the cholesterol easier to associate with atherosclerosis, which he did at the beginning of the research. The cholesterol was declared the cause of all ills. So why the decline does not solve immediately problems with blood vessels? In such cases, the lack of cholesterol may even cause hemorrhage. Scientists continue to look for the causes that lead to vascular injury and develop new therapies.

Fat

cholesterol and cholesterol

The Level of cholesterol depends not only on the availability of surplus food, but also on the quality of fats. And they, too, are different. There are fats needed by the body in order to combat the “bad” cholesterol, increase “good”. This group can be attributed to monounsaturated fats, contained in the following products:

  • Avocado.
  • Almonds.
  • Cashews.
  • Pistachio.
  • Sesame Seeds.
  • Olive oil.
  • Natural walnut oil.
  • Sesame oil.

Polyunsaturated fats also do not clog up our arteries, they should not refuse, but also especially zealous is not necessary. When there is a lack of an atherosclerotic plaque to grow at double speed. These fats are not produced by the body, so they must come from food.

  • Corn oil.
  • Seeds sunflower and pumpkin.

Polyunsaturated fatty acids omega-3 contained in the following products:

  • Seafood.
  • Fatty fish.
  • Hemp oil.
  • Linseed oil.
  • Soybean oil.
  • Walnuts.

Saturated fats raise cholesterol levels, and during the diet to reduce need an extremely to limit in your diet:

  • Beef.
  • Pork.
  • Butter.
  • Fat cheeses.
  • Coconut and palm oil.
  • Sour Cream.
  • Cream.
  • Milk.
  • Ice cream.

The Most dangerous group of fat-TRANS fats. Most of them have been artificially produced from liquid vegetable oils in a special way. After processing, get solid butter (or margarine). TRANS fats not only increase the level of “bad” cholesterol, but also lower rates of “good”. They are often used in the manufacture of semi-finished products, pastries, confectionery, chocolate bars, candies and more.

What is dangerous high cholesterol

cholesterol normal

Cholesterol-is the substance which is always present in our body. It functions as a Transporter, responsible for the delivery of fats to cells. Cholesterol is either "brings up" fat to the blood vessels, takes it from there. But if its concentration is above the permissible limits, it is deposited on the walls. Thus, it can form atherosclerotic plaques, and blood vessels become clogged. Why is it dangerous?

When a large accumulation of bad cholesterol liquid may appear micrometry. Through it rusherythrocytes and platelets, and can form a clot. If the vessel is block by a blood clot, there is the risk of stroke, myocardial infarction, or gangrene of the limb.

Treatment

To reduce the level of cholesterol in your blood, you need to lead a healthy lifestyle. Excess weight should go down. To perform regular exercise. Diet (the foods consumed should not contain saturated fats and TRANS fats).

If a positive lifestyle does not lower cholesterol, are prescribed medicinal drugs from the group of statins. They are able to reduce the level of “bad” cholesterol, prevent stroke or heart attack.

In conclusion, we give three simple helpful hints:

  • Do Not give up fats altogether. This is the source of our energy, protective building material of cell membranes.
  • Monitor the flow of fat in your body. For citizens, the daily rate of fat, if you translate them in calories, should be 600-800 kcal, which is about 30 % of the daily value of the latter.
  • Eat only natural fats. The most useful are those which at room temperature will remain liquid.
