What are the benefits and disadvantages of cholesterol, and what are the harms of high cholesterol

High cholesterol is very dangerous, it is easy to cause atherosclerosis, hypertension and cardiovascular and cerebrovascular diseases, and increase the risk of heart, brain and lower limb vascular complications in diabetic patients.

The main points of the diet are:

Start by limiting food cholesterol to less than 200mg per day. Patients should avoid or reduce the consumption of foods high in cholesterol, such as animal brain, spinal cord, internal organs, egg yolk (each egg yolk contains 250 300mg cholesterol), shellfish (such as mussels, snails, etc.) and molluscs (such as squid, cuttlefish, caviar, etc.). On the other hand, patients should consume moderate amounts of nutrients that are not too high in cholesterol, such as lean pork, beef, duck, chicken, fish and milk.

These foods are not high in cholesterol, for example, each bottle of milk contains only 30mg, and several other foods only contain about 100mg of cholesterol per 100 grams, so there is no need to avoid too much and certainly not eat too much.

The second is to limit animal fats, appropriately increase vegetable oil, calculations show that if animal oil is not used for cooking, then each patient can eat vegetable oil (soybean oil, corn oil, vegetable oil, etc.) 500 750g per month is ideal. Although vegetarian oil is good, it should not be eaten too much, otherwise it will also bring adverse effects.

Third, eat more vegetables, melons and fruits to increase fiber intake.

Fourth, eat more foods that have cholesterol-lowering effects, such as soybeans and their products, onions, garlic, golden cauliflower (grass), shiitake mushrooms, fungus, etc. Some of these foods also have anticoagulant effects, which are also good for preventing thrombosis and coronary heart disease.

What are the dangers of high cholesterol, sterols are indispensable substances in human cells. It is harmless to the human body, but it should not be excessive, otherwise it will cause a series of problems in the human body. So, what are the dangers of high cholesterol and how to lower it?

Let me take you through it in detail. I hope it helps.

What are the dangers of high cholesterol

1. High cholesterol levels in the blood will accelerate the growth rate of prostate cancer in men, which will cause kidney diseases such as kidney failure. For every unit of cholesterol increase, the risk of death from cardiovascular disease increases, as does the risk of vascular-related stroke.

2. High cholesterol will also have an adverse effect on the body's bone health, a large intake of cholesterol, the gap between the teeth and gums will expand, preventing bacteria from entering the groove'Cells lose function and bacteria enter the grooves leading to periodontal disease.

What are the ways to lower cholesterol

1. Eat less or no foods with high cholesterol content such as animal offal and egg yolks, and control the cholesterol intake in the diet, less than 300 mg per day. Blood cholesterol is mainly synthesized by the liver, and only a small part of it is produced in food.

2. Eat less fatty meat and meat oil, and reduce the intake of saturated fat. Saturated fat is widely found in meat, eggs and dairy foods, especially fatty meat, meat oil and offal. Saturated fats have the effect of promoting the production of LDL cholesterol in the blood, and its effect even exceeds that of cholesterol itself.

People with high cholesterol should not and cannot eat foods with high cholesterol content, especially meat, animal oil. It's best to use vegetable allergic travel oil when cooking, and with less oil and less salt. In this way, people's cholesterol can be lowered and the occurrence of three highs can be avoided.

It is recommended that people with high cholesterol eat a light diet and not eat too greasy.

The dangers of high cholesterol

1. High cholesterol in the blood will cause blood vessel stenosis, which will then lead to myocardial infarction, coronary heart disease, etc. This is because excess fat not only accumulates on the coronary arteries in the heart but also on the blood vessels in other areas.

2. After accumulation on the cerebral blood vessels, it will cause cerebral arteriosclerosis, which will lead to cerebral thrombosis and cerebral hemorrhage.

3. After accumulation on the blood vessels of the liver, it will cause fatty liver.

4. After accumulation on the blood vessels of the kidneys, it will cause kidney stones, leading to accelerated failure of kidney function.

5. After accumulation on the blood vessels of the lower limbs, it is very easy to lead to necrosis and paralysis of the lower limbs.

How to lower cholesterol

1. Eat more salmon, sardines, tuna, etc., once a week or even once a day to reduce the intake of saturated fatty acids.

2. Eat more fiber-rich foods, such as grains, bread, blackberries, lentils, dried peaches, etc.

3. Eat more soy products, the isoflavones in soy products can remove LDL-C that harms the arteries.

4. Eat more foods rich in vitamin C, such as papaya, cauliflower, potatoes, etc.

5. Cultivate healthy living habits, exercise more, and enhance physical fitness and immunity.

6. Maintain a positive, optimistic and stable mood in life.

According to Dr. Du, the harms of high cholesterol are: high blood cholesterol levels will accelerate the growth rate of prostate cancer; Cholesterol is known to block or narrow the arteries leading to the heart and is a major cause of heart disease in both men and women. According to the Asia-Pacific Cardiovascular Disease and Stroke Survey, every unit of cholesterol (1 mmol L) in Asians increases the risk of cardiovascular disease death by 35% and the risk of vascular-related stroke by 25%. It's no secret that high cholesterol increases the risk of heart disease, but a new study shows that high cholesterol can also have adverse effects on bone health.

1. The cholesterol in ** can be converted into vitamin D when it receives ultraviolet rays from sunlight.

2. Cholesterol can help the metabolism of carbohydrates (when the amount of carbohydrates is digested, the amount of cholesterol produced is also more).

3. Cholesterol plays an important role in the secretion of adrenocortical hormones (such as cortisone) and sex hormones, which are necessary for life.

4. Cholesterol is the element that makes up various membranes and produces male and female hormones.

Cholesterol acts differently depending on the type of lipoproteins that go with it, and lipoproteins are the building blocks of blood that transport cholesterol.

The human body contains about 140 grams of cholesterol, of which 25% is not divided into brain and nerve tissues, and cholesterol is mainly synthesized in the body, and the human body synthesizes 1 2 grams per day. An increase or decrease in serum cholesterol is a manifestation of the disease.

Cholesterol is divided into high-density cholesterol and low-density cholesterol, the former has a protective effect on the cardiovascular system, usually called "good cholesterol", and the latter is high, the risk of coronary heart disease will increase, usually called "bad cholesterol". Blood cholesterol levels range from 140,199 milligrams per unit to a relatively normal cholesterol level.

There are two kinds of cholesterol, one is high-density and the other is low-density, high-density lipoprotein is good, it can engulf low-density lipoprotein, which is good for health, and low-density lipoprotein is not good, and it is easy to get high-blood lipid diseases.

Cholesterol is one of the basic lipid compounds in the body. It is a component of the body's cell membranes, involved in the synthesis of sex hormones, and our brain cells are almost entirely made of it. That is, this substance is necessary for our body.

In fact, there are two sides to cholesterol, there are harmful and light cholesterol, and there are also beneficial and heavy cholesterol. Good cholesterol absorbs and effectively uses the harmful cholesterol in the fatty foods that the body eats in the liver. Doctors know the inevitable link between "bad" cholesterol levels and ischemic disease of the heart (which all experts agree is the cause of the first fatal disease).

Cholesterol levels can largely predict dangerous vascular disease. Grigory Arujunov, MD, head of the Department of Internal Medicine of the Moscow Department of the Russian National Medical Academy, said. "If an 18-year-old has a cholesterol level of 12 millimoles (the standard is millimole liters), then it is absolutely safe to say that the person will have a heart attack by the age of 30.

It is not only itself that flows in the bloodstream, but is also a macromolecule that combines fat and protein. The scientific name is lipoprotein. "Bad" cholesterol is made up of low-density lipoproteins that are easily deposited in the lining of blood vessels.

The doctor said that the "bad" cholesterol with yellow streaks can be seen on the inner wall of the blood vessels of 15-year-olds. As cholesterol continues to be deposited, the gaps in the blood vessels narrow. If the walls of the damaged blood vessels become inflamed, causing a disconnect in the deposited cholesterol (cholesterol "gasket"), a blood clot ——— a blood clot can appear at the fault site.

If the aorta has many cholesterol "gaskets," doctors diagnose atherosclerosis. In addition to high cholesterol, excess salt, smoking, and lack of exercise are also factors in the occurrence of atherosclerosis. In the worst-case scenario, the clot breaks away from the wall of the blood vessel and travels through the bloodstream.

This wandering can lead to infarction, stroke, blockage of blood vessels in the lungs and feet, and other diseases.

The average cholesterol level for residents in Russia is 6 millimol liters, and in the United States it is millimolar liters. The human body does not need more than 300 mg of cholesterol per day and night. From food we get an average of 400 mg.

Sausage contains 1114 mg of cholesterol per 100 grams and Pacific cod contains 14 mg of cholesterol per 100 grams.

Limit the intake of fatty foods, especially for older people, who should remember this better. Find out about the amount of unnecessary cholesterol in fatty meats, caviar, sausages, butter and other delicious foods or talk to your doctor. In some countries, the main food is rice and vegetables, and almost no inhabitants suffer from atherosclerosis.

However, it is not easy to completely change your eating habits. Dr. Grigory Aruyunov believes that drugs can be used to lower cholesterol levels on the advice of doctors.

Cholesterol is also known as cholesterol. A derivative of cyclopentane polyhydrophenanthrene. As early as the 18th century, cholesterol was discovered from gallstones, and in 1816 the chemist Bencher named this lipid substance cholesterol.

Cholesterol is widely found in animals, especially in brain and nerve tissues, and is also high in kidneys, spleen, liver, and bile. Its solubility is similar to that of fat, insoluble in water, soluble in ether, chloroform and other solvents. Cholesterol is an indispensable and important substance in animal tissue cells, which not only participates in the formation of cell membranes, but also is the raw material for the synthesis of bile acids, vitamin D and steroid hormones.

There are two distinct and one-sided views on the role of cholesterol in food. One view is that cholesterol is extremely harmful and should not be eaten. This view is one-sided because people who hold this view do not have a clear understanding of the role of cholesterol in the body.

In fact, cholesterol is a component of cell membranes and is involved in the biosynthesis of some steroidal hormones and bile acids. Since many foods containing cholesterol are also rich in other nutrients, if you avoid such foods too much, it is easy to cause nutritional imbalance, leading to anemia and other diseases. Another view is that cholesterol is not harmful to the human body and can be consumed as much as possible.

This view is wrong because of the lack of understanding of the pathogenesis of hyperlipidemia and coronary heart disease. Long-term excessive intake of dietary cholesterol will lead to the occurrence and development of atherosclerosis and coronary heart disease.
