What is the normal level of cholesterol in the blood? Cholesterol and its types. Reducing cholesterol levels Normal cholesterol levels in human blood

Blood cholesterol levels are an important indicator of health. Cholesterol is present in every organ, every cell membrane and muscle. Without this substance, the construction of the skeleton, the regeneration of damaged tissues, metabolism and the production of important sex hormones, such as testosterone, estrogens and cortisol, are impossible.

A person gets only 20% of cholesterol from food, in particular, from animal fats, meat, some types of proteins and other products, and the remaining 80% is produced in the human liver.

What is cholesterol?

Cholesterol is usually divided into “bad” and “good”. Both forms are found in the blood plasma as part of lipoproteins: complex compounds consisting of fats and proteins.

“Good” cholesterol is the common name for high-density lipoproteins (HDL). The main function of “good” cholesterol is to continuously transport excess cholesterol from the blood to the liver for processing and further elimination from the body. Therefore, such cholesterol actively protects the body from serious diseases and cleanses the internal walls of blood vessels.

In contrast, “bad” cholesterol settles inside the artery walls, forming plaques. It combines with apoproteins (special types of protein) and forms fat-protein complexes (LDL). An increase in the level of this particular cholesterol is dangerous to health.

What happens when cholesterol levels are high?

High cholesterol levels can cause:

  • atherosclerosis;
  • arterial damage;
  • myocardial infarction;
  • angina pectoris;
  • cardiovascular diseases;
  • stroke and mini-stroke.

How can you regulate blood cholesterol levels?

The only way to increase the level of “good” cholesterol is through physical activity: moderate to moderate physical activity on the body can increase its production. A low-carbohydrate diet will also help reduce “bad” cholesterol. The consumption of margarine, mayonnaise, chips, baked goods, fried foods and semi-finished products should be avoided.

How to find out your cholesterol level?

To find out your cholesterol level, you should do a biochemical blood test. The test can be taken at almost any clinic; for this, approximately 5 milliliters of blood are taken from the cubital vein. It is important to know that before taking a cholesterol test you should not eat anything for 12 hours and limit yourself in physical activity.

It is very important to maintain normal blood cholesterol levels. After all, our health, longevity and joy in life depend on it.

Today I offer readers a few numbers, knowing which you can independently monitor the indicator of a biochemical blood test, namely cholesterol level.

As mentioned in the previous article, cholesterol is the main element included in the cell membrane and in the sheaths of nerve fibers. Blood cholesterol levels affect the stability of the immune system, and therefore the body’s defense against cancer.

The hormonal system (especially sex hormones and adrenal hormones) performs its functions through the production of cholesterol. Without cholesterol, vitamin D is not absorbed by the body. And the functioning of the brain also largely depends on cholesterol in the blood, and most importantly, on its normal level.

Level of cholesterol and its components in the blood

  • Cholesterol and lipoprotein levels are measured in Russia and other countries in different units. In Russia - in millimoles per liter, in other countries - in milligrams per deciliter.

♦ Cholesterol (cholesterol) is a fatty alcohol that is insoluble in water, but soluble in fats (lipids). It is lipids that carry or transport cholesterol through the blood vessels of our body.

By the way, patients with cardiovascular diseases and diabetes are recommended to maintain total cholesterol below 4.5 mmol/l.

♦ LDL – low density lipoproteins or "bad cholesterol".

LDL – forms atherosclerotic clots (plaques), narrowing the lumen of blood vessels and causing disruption of the blood supply to organs. A high level of LDL in the blood is dangerous because there is a risk of developing atherosclerosis, which leads to myocardial infarction and stroke.

LDL concentration levels

♦ HDL - high density lipoproteins or "good cholesterol". HDL - “clean” the arteries and thereby remove cholesterol from the vascular walls. A high level of HDL concentration in the blood can reduce the risk of atherosclerosis and other cardiovascular diseases.

HDL concentration levels

♦ Triglycerides – an increase in this indicator is a serious health problem. For example, in the functioning of the thyroid gland or metabolic syndrome.

  • Normal triglycerides– 2.0 mml/l (180 mg/dl). The normal triglyceride level increases with age.

——————————————————————————————————-

Cholesterol, the norm of which has long been scientifically established for men and women, is one of the most important, but at the same time, the most dangerous compounds in the human body. Its structure is a fatty alcohol, which, when accumulated in excess, provokes the development of atherosclerosis, one of the most dangerous vascular diseases. Cholesterol is produced by the liver, but its level is affected by the food a person eats. It is an essential building element that is part of the structure of cell membranes. It is involved in the production and synthesis of hormones. By structure, it is presented in the body in the form of lipoprotein compounds, which are divided into low-density cholesterol, otherwise it is also called bad (LDL), and high-density is called good (HDL). Cholesterol is a fatty alcohol, otherwise called “cholesterol” and is considered one of the most dangerous for human health.

General characteristics and types of cholesterol

According to many, cholesterol is a dangerous substance that should be present in a minimal amount in the adult body, but in fact it performs the most important functions of cell structure in the body. The content of lipoproteins in the blood determines the functioning of all organs and systems in the body; therefore, the higher it is, the worse the condition of the body as a whole. Total cholesterol levels in women and men are divided into good (LDL) and bad (HDL). Atherosclerotic plaques that clog blood vessels and clog their walls are called bad cholesterol. It combines with appoprotein and forms fat-protein complexes - LDL. Elevated LDL levels are dangerous for human health. The normal level in a healthy person is determined using an analysis and is determined in the laboratory by indicators in mmol/l or mg/dl:

  • in a healthy person, the normal level of bad LDL should be at least 3.5 mmol/l. A decrease or increase in this level is considered a pathology and requires adjustment with a special diet and medications;
  • for heart pathologies, the cholesterol level should be 2.1 mmol/l;
  • in the absence of heart disease, but in the presence of more than two risk groups, cholesterol should not exceed 2.9 mmol/l

There are many factors that determine normal LDL levels, so only a specialist can diagnose elevated lipoprotein levels after conducting a comprehensive blood test. Along with LDL, high-density lipoproteins, also known as HDL, are observed in the body. The function of HDL is not to settle on the walls of blood vessels, but to combine protein and fat in order to remove them from the body.

LDL cholesterol levels and CVD risk

Normally, a lipoprotein test should show an increased level of HDL and a decreased level of LDL, but according to statistics, 60% of men and women aged 40 to 60 years have high bad cholesterol and lower than normal good cholesterol. Unlike LDL, high-density lipoprotein is produced in the body, unlike HDL, because bad low-density cholesterol is taken into the body through food.

Cholesterol in women is normally higher than in men, which is explained by hormonal levels. The only way to increase HDL levels is through physical exercise, which also promotes normal blood circulation, which prevents the accumulation of bad cholesterol on the walls of blood vessels.

Active muscle work can reduce LDL and increase HDL readings. Cholesterol levels change with age, most often in women after 55 years, and in men after 60 years. It is normal for LDL and HDL levels to increase or decrease with age, but it is important to monitor the indicators that are normal for men and women:

  • in a healthy person, the normal level of bad cholesterol is 0.9 mmol/l or 38 mg/dl;
  • in adults who have had heart disease, after 50-60 years of age it should be 0.8 - 1.6 mmol/l or 45-65 mg/dl.

How to take flaxseed oil to lower cholesterol

An analysis of total cholesterol in a healthy person should consist of HDL and LDL, against which the general analysis is determined. In the body of a healthy person, it should normally be 4.9 mmol/l in men, and in women - 0.2 - 0.4 mmol/l higher. For adults, even a slight increase in total cholesterol levels should be considered a deviation from the norm, especially after heart attacks and strokes. Elevated low-density lipoprotein in excess or a decrease in goodness does not have any symptoms, so changes in the general analysis may not be accompanied by any signs. A decrease in HDL and an increase in LDL in the body is manifested by characteristic pain in the chest area, which is the main symptom of a general level of lipoproteins above normal.

Elevated cholesterol contributes to the formation of thrombosis

A higher than normal level of cholesterol in the blood is fraught with the formation of atherosclerotic plaques - a disease that is accompanied by the accumulation of bad cholesterol inside the blood vessels, and even diet cannot lead to positive results. When low-density blood cholesterol becomes excessive, it clogs blood vessels, causing blood obstruction. Elevated cholesterol promotes thrombosis, which is fatal, so monitoring lipoprotein levels is vital, especially for the elderly, after the age of 55-60 years.

What is the normal cholesterol level?

A healthy person who does not feel any discomfort rarely thinks about checking blood cholesterol for abnormalities. A total cholesterol test for heart disease is normal. What normal cholesterol should be depends on age, gender and lifestyle. High cholesterol in the absence of accompanying symptoms can occur in a certain population group, which is included in the category:

  • smokers;
  • obese people;
  • hypotensive;
  • people with heart disease;
  • men over 50 years old;
  • women over 40 years of age;
  • people over 60 years of age.

Reducing cholesterol quickly and easily

To test for bad cholesterol, you need to do a biochemical test, which will show whether the cholesterol level in the blood is normal or not. It is done in any clinic, and it requires approximately 5 ml of venous blood. In order for the analysis to be as accurate as possible, you must not eat anything 12 hours before the procedure and avoid physical activity. In order not to constantly go to the clinic and take a blood test, you can purchase a special device for measuring lipoprotein levels at home. This is a disposable express strip that allows you to quickly and accurately determine the level of LDL and HDL.

Smoking increases cholesterol levels

Normal cholesterol levels

A blood test is done to determine total cholesterol, which includes 2 indicators: the level of good cholesterol and the level of bad cholesterol. The norms for LDL and HDL are different, so they need to be correlated with the norms by age, according to the table of norms for men and women. There is no specific number that is the norm for cholesterol for an adult.

There is a table that shows the recommended level, which in this range cannot cause harm to human health. If it is higher or lower, this does not mean that a person has a cholesterol level disorder, since there are indicators that affect the determination of the level as normal.

Beta lipoproteins are a source of excess cholesterol in the blood. The assessment of low-density lipoproteins is made on the basis of a biochemical blood test, where the coefficient of LDL beta cholesterol and HDL alpha cholesterol is established. These 2 indicators should be normal within the age table. Blood cholesterol levels by age:

  • below 2.9 – good;
  • 2.8 – 4.2 – normal;
  • above 4.5 – elevated.

LDL cholesterol level:

  • below 0.9 is a good level for people with heart disease;
  • below 1.8 is a good level for people predisposed to heart disease;
  • below 2.1 – good;
  • 2.0 – 4.3 – acceptable;
  • above 4.6 – 5.8 – increased;
  • above 6.0 – very high.

A blood test is necessary to determine the level of cholesterol in the blood

HDL “good” cholesterol levels:

  • below 1.1 mmol/l for men and below 1.5 mmol/l for women – low;
  • 1.4 – 1.6 mmol/l in men and 1.2-1.6 mmol/l in women – good;
  • Above 1.8 mmol/l – elevated.

Normal blood cholesterol levels in women

To find out what the norm is for HDL and LDL, you need to correlate it with age. This indicator is decisive in order to identify bad cholesterol in time and bring it back to normal. It is important for women to start worrying about their health as early as possible: eliminate foods containing bad cholesterol from the diet, get rid of bad habits and exercise so that the cholesterol level in the blood is always normal. Normal cholesterol levels for women are:

  • 20-25 years old – 2.8-4.6;
  • 30-35 years old – 3.0-5.2;
  • 35-40 years old – 3.2-6.0;
  • 45-50 years old – 3.4-6.4;
  • 50-55 years old – 3.9-6.7;
  • 55-60 years old – 4.1-7.4;
  • 60-65 years old – 4.2-7.6.

Causes of cholesterol disorders in men

Much in determining the normal indicator depends on how much it should be in the presence of concomitant indicators such as heart disease, kidney failure, excess weight and thyroid function.

Treatment of high cholesterol

Treatment of high cholesterol should be comprehensive. Drug treatment is not always justified, especially if such treatment is not prescribed by a specialist. Treatment of atherosclerosis must be accompanied by proper nutrition. To reduce the level of atherosclerotic plaques, you must follow a diet. The diet is based on eating foods that contain minimal cholesterol. The diet includes:

  • fruits and vegetables;
  • cereals and cereals;
  • low-fat fermented milk products;
  • vegetable oils;
  • nuts and dried fruits;
  • green tea.

The diet does not limit the consumption of lipoproteins; the main thing is to exclude the intake of trans fats, which contribute to the accumulation of plaques on blood vessels. The diet requires steaming food. Salads can only be dressed with vegetable oil. Butter, baked goods and sweets should be excluded from the diet. Treatment of atherosclerosis can be carried out with herbal preparations and fresh juices, which wash away the accumulation of fats from the vessels and have a general strengthening effect on the body.

Treatment of atherosclerosis should be carried out under the supervision of a specialist so that the diet helps reduce the level of atherosclerotic plaques and not worsen the patient’s condition. Not only diet is also important, it is necessary to engage in physical activity, since this is the simplest and most effective method to reduce bad cholesterol. Sports can be used to prevent atherosclerosis. Before starting treatment for atherosclerosis, it is recommended to consult a specialist to ensure there are no contraindications.

Everyone has heard that with high cholesterol, the risk of cardiovascular disease also increases. But what kind of cholesterol is considered high? Taking a cholesterol test is not difficult - but it turns out that not every doctor can correctly determine your cholesterol level. If you or your loved ones are concerned about “bad” cholesterol, cardiologist Anton Rodionov will help you understand cholesterol standards.

Do you want to earn some money? I'll give you a great idea. Make a bet (for a small amount so that no one is offended) that cholesterol is alcohol. Your interlocutor, of course, does not believe you and is ready to argue. You open any serious reference book... And to your great joy, you are convinced that I (and now yours) are right. The winnings are yours.

Cholesterol was isolated at the end of the 18th century; it got its name from two words: “chole” - bile and “sterol” - fatty. And in the middle of the 19th century, chemists proved that, in terms of its chemical structure, it belongs to the class of alcohols. Therefore, in some countries it is called “cholesterol”. You remember from school chemistry that all alcohols end in “ol”: ethanol, methanol, etc.

Some laboratories use the English transcription - cholesterol. Cholesterol and cholesterol are synonyms.

High cholesterol: why do I have it?

Cholesterol is completely different from those alcohols that cause intoxication and intoxication, however, its excess is not at all beneficial for the body. However, it is also impossible to live completely without cholesterol. Cholesterol is a building material for the cell wall, it is the precursor of all steroid hormones (cortisol, aldosterone, sex hormones).

There is a common belief that high cholesterol occurs only in those people who eat a lot of fatty foods. Nothing like this. 80% of cholesterol is produced in the body (in the liver, in other tissues) and only 20% of cholesterol comes from food. But the amount of cholesterol that is produced by the body depends... correctly, on heredity.

Consequently, a completely herbivorous person, a convinced vegetarian who has only seen meat in a picture, may have high cholesterol. Corollary number two: if your immediate family has high cholesterol, then you need to monitor it more often. Finally, consequence number three: it is often impossible to reduce high cholesterol with diet alone.

As you know, gasoline does not burn on its own. In order for it to ignite, a spark is needed. In the same way, cholesterol by itself does not stick to absolutely healthy blood vessels. In order for its deposition in the vessels to begin, some kind of “match” is needed. Other risk factors become such a match: smoking, diabetes, hypertension, excess weight, that is, everything that in itself damages blood vessels, making them more vulnerable to the development of atherosclerosis.

Alas, many people carry such matches with them... This is why, by the way, atherosclerosis often develops in people with relatively low cholesterol - there is not much gasoline, but a whole box of matches.

Facts about cholesterol

  • Cholesterol is 80% synthesized by the body and only 20% comes from food.
  • Smoking, hypertension, diabetes mellitus provoke the development of atherosclerosis even with normal cholesterol levels.
  • The most important risk factor for complications is “bad” cholesterol (LDL).
  • Indicators of total cholesterol and LDL do not have the lower limit of normal. Less is better.
  • In principle, vegetable oils cannot contain cholesterol.
  • It is difficult to reduce cholesterol only by changing your diet.

Cholesterol: good and bad. What is the difference?

Everyone has heard about “good” and “bad” cholesterol. The fact is that cholesterol itself is an insoluble molecule and cannot simply enter tissues. He needs a special “transport”. Special carrier proteins act as “carriers” of cholesterol. Moreover, among them there are those that “deliver” cholesterol into the tissues, where it will be deposited, contributing to the development of atherosclerosis, and there are proteins with the help of which cholesterol, on the contrary, is removed from the body.

In medical parlance, “bad” cholesterol is called "low-density lipoproteins" (LDL, LDL, LDL). It is this indicator that we will look for in a biochemical blood test in order to determine the degree of risk. "Good" cholesterol is “high density lipoproteins” (HDL, HDL, HDL). The higher its level, the better the excess cholesterol is removed from the body.

When cholesterol is deposited in the vessel wall, an atherosclerotic plaque begins to form. It grows and begins to narrow the vessel. While the narrowing is 20-30%, the person does not feel anything. When it blocks the lumen by 50-60%, the remaining 40% is not enough to let the required amount of blood through, ischemia develops. Cardiac ischemia is called - the heart needs more blood, but a narrowed (stenotic) vessel cannot provide it.

If the plaque is loose, fragile, inflamed, it can collapse and rupture. The body perceives damage to the plaque as an injury, and platelets—blood cells that are responsible for stopping bleeding—come to the site of the damage. A blood clot forms in the vessel, which means that blood flow suddenly stops and part of the tissue of the heart, brain or other organ is suddenly left without blood and dies.

This process is called a “heart attack”. If a catastrophe occurs in the heart - this is, in the brain -, in the artery of the leg - gangrene.

Cholesterol analysis: lipid spectrum

In order to determine cholesterol metabolism and estimate the amount of “good” and “bad” cholesterol, a blood test is performed, which is called lipid spectrum(lipid profile, lipidogram). This includes:

  • Total cholesterol
  • LDL cholesterol (“bad”)
  • HDL cholesterol (“good”)
  • Triglycerides

Triglycerides- This is another indicator of fat metabolism, one of the main sources of energy in humans. It is believed that an increase in triglyceride levels in itself is not as dangerous in terms of cardiovascular risk as an increase in cholesterol. High triglycerides are primarily a risk factor for pancreatitis.

Unlike cholesterol, triglycerides are practically not produced in the body, but mainly come from food. So I can sometimes believe that a patient with high cholesterol is actually following the recommended diet, but if his triglycerides are elevated, this means that he is eating much more animal fat than necessary.

Cholesterol norms: table. Cholesterol test interpretation

So, we received the results of the blood lipid test. The next thing we need to do is cross out the “norm” box in this analysis. Yes, yes, don't be surprised. Exactly. Not a single laboratory in the country knows cholesterol standards. This indicator is constantly being revised by the global medical community, but for some reason this secret knowledge does not reach laboratories.

First of all, let's agree that there is only high cholesterol, but there is no such thing as low cholesterol. There is no lower normal limit for cholesterol. The lower the cholesterol, the better. To ensure the vital needs of the body (cell construction, hormone synthesis), very little cholesterol is needed, and none of the modern treatment methods can reduce cholesterol so much that these functions are affected.

After we have crossed out (or covered up) the “norm” on the form, let’s enter there what is actually considered today target blood lipid test values.

  • Total cholesterol<5,0 ммоль/л
  • High-density lipoproteins >1.0 mmol/L for men and >1.2 mmol/L for women
  • Triglycerides<1,7 ммоль/л

But the target value of “bad” cholesterol (LDL) depends either on the presence of concomitant diseases.

Low-density lipoprotein (LDL-cholesterol) target values

Cholesterol levels. Should I lower my cholesterol?

Once we have determined our LDL target values, Operation Cholesterol enters its final phase. We have to understand whether it is necessary to reduce cholesterol with medications or whether it is enough to change the diet to influence that same 20%.

Let's look at this table. At first glance it looks complicated, but in reality everything is not so complicated. Horizontally we find our level of “bad” cholesterol (LDL), and vertically we find the category of cardiovascular risk.

What to do depending on your cholesterol level and calculated risk

SCORE Risk (%) LDL-C level
1.8 to2.5 to4.0 to> 5.0 mmol/l
No lipid reduction required Healthy lifestyle Healthy lifestyle
> 1% upHealthy lifestyle Healthy lifestyle Improving lifestyle, possibly prescribing medications if the target level is not achieved Improving lifestyle, possibly prescribing medications if the target level is not achieved Improving lifestyle, possibly prescribing medications if the target level is not achieved
>5% up Improving lifestyle, possible prescription of medications Improving lifestyle and immediate prescription of medications Improving lifestyle and immediate prescription of medications
> 10%, or very high risk Improving lifestyle, possible prescription of medications Improving lifestyle and immediate prescription of medications Improving lifestyle and immediate prescription of medications Improving lifestyle and immediate prescription of medications Improving lifestyle and immediate prescription of medications

Previous myocardial infarction, surgery on the heart and blood vessels.

Several risk factors, when assessed using the SCORE table, the total risk is > 10%.

Coronary heart disease, severe atherosclerosis of the carotid arteries, diabetes mellitus.

Several risk factors, when assessed using the SCORE table, the total risk is 5-9%.

Several risk factors, when assessed using the SCORE table, the total risk is 1-4%.

Family history of early cardiovascular disease (onset of coronary artery disease or other vascular disease in immediate male relatives< 55 лет, по женской — < 65 лет).

One risk factor, when assessed using the SCORE table, the total risk< 1%.

Then everything is simple. Let's look at what is written in the box at the intersection of the bad cholesterol level and the risk category. By “improving your lifestyle” we mean changing your diet, losing weight and quitting smoking. If "medication" is recommended, then statins should be started.

We'll talk about dieting for high cholesterol and taking statins next time.

Now you can see the fashion for proper nutrition and sports: people have begun to monitor their health more carefully. This is very good, but many people have the wrong idea about certain concepts. For example, what would the average person say about cholesterol? Most likely, cholesterol is basically bad, and the largest amount of it is found in eggs. But in reality, everything is much more complicated and we should understand this issue in more detail.

What is cholesterol

People without medical education do not know what cholesterol is and the name itself sounds threatening to them. In Russian and foreign practice, a word such as cholesterol is used.

Cholesterol is a fatty alcohol and is needed to give cell membranes strength. Most of the cholesterol, namely 80%, is produced by the liver, and the remaining 20% ​​enters the body with food. It is worth noting that not only increased cholesterol levels have a negative impact on health, but also low ones. Yes, the body cannot function normally without fatty alcohol.

To find out if the cholesterol in your blood is normal, you need to know that there are two types of cholesterol! LDL, which is conventionally called “bad”, however, it is from it that hormones are produced, as well as vitamin D. If the level of LDL is too low, the risk of depression and nervous disorders will significantly increase. HDL is the so-called “good” cholesterol, which protects us from heart attack and stroke, if, of course, it is within normal limits.

Chemical formula of cholesterol C 27 H 46 O

Norms of LDL (low density lipids)

  • It is necessary to ensure that low-density lipids in the blood do not exceed 2.58 mmol/l.
  • Slightly elevated lipid levels – up to 3.34.
  • Decently elevated - up to 4.12, it is worth thinking about changing your lifestyle.
  • High – up to 4.9
  • Very high, critical level – above 4.9

HDL (high-density lipid) standards are slightly different

  • Increased risk of cardiovascular disease if blood levels are less than 1.036 mmol/L for men and less than 1.29 mmol/L for women.
  • The level of “good” cholesterol in the blood of a healthy person should be above 1.55 mmol/l.
    Doctors recommend getting tested every five years starting at the age of twenty.

What foods lower blood cholesterol?

With an incorrect, unbalanced diet, as well as in the absence of physical activity, it can happen that the level of cholesterol in the blood will be significantly increased. Of course, this will ultimately negatively affect your well-being and overall health. However, unpleasant consequences can be prevented if you simply change your diet. First of all, it is necessary to completely eliminate alcohol and fast food.

Including the following foods in your diet

Legumes. The average person, for some reason, does not eat beans, lentils or chickpeas. Although these foods are rich in protein, they contain a large amount of vitamins and fiber, which help lower cholesterol levels. Don't forget to consume at least 30 grams of fiber daily.

Fruits and vegetables. Every day you need to eat at least a small portion of vegetables and fruits. These foods, like legumes, contain large amounts of fiber. In addition, fruits and vegetables help compensate for the lack of many vitamins, macro and microelements.

Nuts. Cashews, almonds, hazelnuts, walnuts and pine nuts should be present in your diet daily. They contain a large amount of healthy fats, which regulate cholesterol. It is important to remember that nuts are a heavy product and should not be consumed in large quantities.

Causes and foods that contribute to the formation of cholesterol in the blood


Many people mistakenly believe that eliminating all foods that contain cholesterol from their diet will improve their health. In fact, this is not entirely true, as when you eat a diet, the liver begins to produce more cholesterol, which means you can get the opposite effect.

The smart approach is to eat right and... In addition, it often happens that high blood cholesterol levels are not related to diet, and there are other reasons for this:

  • Excess weight and impaired metabolism.
  • Heredity.
  • Smoking and alcohol.
  • Some diseases are hypothyroidism, diabetes mellitus, hypertension, kidney disease, liver cirrhosis.
  • Use of oral contraceptives or hormonal steroids.

Cholesterol levels in men usually begin to rise after age 35. In women, if there are no pathologies, it is normal until menopause.

Foods that increase blood cholesterol levels include:

  1. Fatty pork and beef. It is best to replace it with chicken or completely exclude it from the diet, adding more fish and seafood.
  2. High-fat dairy products, especially margarine. You don't have to completely give up dairy products, you just need to reduce your consumption.
  3. Coconut and palm oil.
  4. Fast food. Avoid fried foods as they contain large amounts of trans fats. They not only increase cholesterol levels, but also have a negative impact on health in general.

Until recently, it was believed that egg yolk could significantly increase blood cholesterol levels. Actually this is not true. If you eat right and your diet contains a minimum of harmful foods, then even 3-4 yolks a day will not harm, but will only be beneficial. It is the yolk that contains large amounts of vitamin D, B4, B9, B12, selenium and phosphorus.

Good and bad cholesterol

As mentioned above, there is such a thing as “bad” and “good” cholesterol. “Bad” cholesterol includes low-density lipids LDL. There should not be too many of them in the blood, as they can ultimately lead to atherosclerosis. LDL levels need to be regulated - eat the right foods, give up bad habits and exercise.

High-density lipids (HDL) are also called “good” cholesterol. This type of cholesterol is simply necessary for normal life. If it is not enough, then the cells are renewed more slowly than necessary. It affects bone growth and the synthesis of sex hormones, which is especially important during adolescence.

Drugs that lower blood cholesterol quickly and effectively

Niacin. You should start taking this drug only after prior consultation with your doctor. Reception begins with small doses - 100 mg, gradually increases to 4 grams.

  • Insomnia and headache.
  • Amnesia, malaise and dizziness.
  • Vomiting, diarrhea, pancreatitis.
  • Impotence and obesity.

First of all, doctors recommend completely abstaining from red meat (beef, pork, veal). You can easily get proteins and vitamins from chicken, fish, legumes or nuts. Reduce foods such as butter, full-fat milk and cheese from your diet. Use them extremely rarely or give preference to low-fat options.

Your diet should include cereals, vegetables, nuts, vegetable oils and herbs every day. Add bran to porridge, but no more than two tablespoons, and completely avoid foods fried in oil.
