How is cholesterol produced? What are the dangers of cholesterol? Why?

Congenital genetics and acquired lifestyle are the main causes of high cholesterol. Familial hypercholesterolemia is an autosomal dominant disorder in which patients are not obese or even thin, but have very high cholesterol. Nowadays, many young people overeat high-fat, high-calorie, high-cholesterol foods, do not like to eat vegetables and fruits, do not pay attention to exercise, these bad habits, even if they are thin people, cholesterol will "exceed".

Diabetes, nephropathy, hypothyroidism and other diseases may lead to high cholesterol, so it is very necessary to go to the hospital for regular check-ups, and once you find that your cholesterol is high, you should be in time. How to Prevent High Cholesterol The most important thing to prevent cholesterol is to pay attention to the combination of diet. In order to lower cholesterol, we should reduce the intake of high-cholesterol substances, especially some greasy fatty meat, hearts, animal offal, no more than 3-4 eggs per week, especially try to eat less egg yolks, including all kinds of fish eggs and crab yolks.

The staple food should be paired with some coarse grains, while the non-staple food should be fish, lean meat, beans and soy products, and various fresh vegetables and fruits. Do 30 minutes of aerobic exercise three times a week, moderate physical activity can improve cardiovascular function, blood circulation and microcirculation, and has a good effect on preventing cholesterol.

1. First of all, cholesterol is a substance that exists in animal tissue cells, like some fish, animal offal and squid, which will synthesize cholesterol after entering the human body, some of which will be metabolized out of the human body, and some will remain in the body to form bile acid, form cell membranes and synthesize hormones.

2. The second is the main food where cholesterol exists, mainly in pig brain, pig liver, pig lung, pig spleen, every animal is like this, as well as shellfish food, such as fresh shellfish and red shellfish, and finally some cream, butter, sheep fat and lard These foods all have cholesterol.

3. Finally, it is a reasonable diet, reduce cholesterol, eat less fatty meat and meat oil, eat more vegetables, fruits and fungi and algae foods, such as fungus, kelp and wakame, so that cholesterol will not increase, and cholesterol will even cause gallstones, so it is necessary to match the diet reasonably.

Hypercholesterolemia is often caused by too much high-cholesterol and high-calorie food intake and too little exercise. The safest way for patients with hyperlipidemia is to control their diet, avoid tobacco and alcohol, eat more lightly, reduce the intake of edible oil, fried food, high cholesterol and high-fat food, and at the same time adhere to a certain amount of physical exercise.

What are the dangers of cholesterol? Why? For a long time, there has been a deep misunderstanding of cholesterol.

Although high cholesterol can bring harm to human health, we should not talk about cholesterol because of this, or even think that cholesterol is a type"Bad stuff"。But in fact, cholesterol is one of the essential nutrients for the human body, and the body usually needs a certain amount of cholesterol to function properly. Cholesterol is one of the basic building blocks of the body's cells.

It is also an essential nutrient for growth and development, brain development, and the maintenance of various functions of the body. For example, it is a raw material for the synthesis of bile acids, hormones, sex hormones, and vitamin D, as well as a component of the brain, liver, and other vital organs. I remember when I was in college, many of my classmates did not eat egg yolks when they ate eggs, cholesterol was very high, and eating it was not good for the body, and even college students in their 20s were worried about the impact of cholesterol, which was easy to cause high blood pressure in the elderly, not to mention, cholesterol was also high, and many people simply did not touch eggs, and it seemed that eating a little blood lipids would soar.

In fact, cholesterol itself is not terrible, our body is also synthesizing it every day, it is an essential substance. Cholesterol is an important building block for building cells and is used to make cell membranes. Cholesterol is also a building block of vitamin D, bile acids, and some of the body's most important hormones.

We put it so important"Heroes"It's a profound misconception to be seen as a monster. What's more, not all of the cholesterol we need comes from food. In fact, we only get 20 to 30 percent of the cholesterol our body needs from food every day.

The remaining 70 to 80 percent comes from the liver. And only a small fraction of the cholesterol we eat from food is directly absorbed, and most of it is broken down into smaller units to wait**. In order to reduce blood lipid levels, some friends deliberately control the intake of cholesterol, in fact, this effect is not great, as we said earlier, most of the cholesterol in our body is self-synthesized, and it is useless to control the diet.

And if our cholesterol levels are too low, it can lead to stroke and depression. Of course, if the cholesterol is too high, it can also lead to blood clots, high blood pressure and other diseases, so it is not good to have too high or too low cholesterol, and everything should be appropriate.

Genetic factors: such as familial hypercholesterolemia, which is caused by genetic defects, and it is generally impossible to change genes;

2. Environmental factors: most of them are caused by poor diet and exercise habits. In terms of diet, patients often eat oily and fatty foods, such as animal oil when stir-frying, and like to eat fatty meats, including beef, mutton, and pork, which have high cholesterol content.

Some people like to eat animal offal, or baked and fried foods, such as fried onion rings, french fries, fried chicken wings, and cream cakes, which can easily lead to high cholesterol levels. In order to reduce blood lipids, it is necessary to reduce the intake of animal fats and trans fatty acids, and increase the intake of vegetables and fruits.

High cholesterol is mostly caused by incorrect diet, overeating three meals, high fat content, easy to eat fried food, small amount of exercise, and fat accumulation in the body over time is easy to get obesity. Moreover, if cholesterol is high, triglycerides will also be high, and another reason for high cholesterol is genetic factors. The best ways to lower cholesterol include dietary control and strengthening exercise to consume energy, as well as using drugs to control it, such as statins or fibrates, and niacin.

If cholesterol is high for a long time, it will lead to a series of diseases such as high blood pressure, fatty liver, liver cirrhosis and cardiovascular and cerebrovascular diseases, which will greatly increase the risk of disease. Therefore, it is necessary to prevent and control the risk factors of hyperlipidemia, such as avoiding smoking, limiting alcohol, avoiding staying up late, eating a light and healthy diet, staying away from fried foods, such as fatty meat, etc., and strengthening exercise.

Cholesterol is an important indicator of clinical biochemical examination, under normal circumstances, cholesterol synthesized by the body in the liver and ingested from food will be converted into steroid hormones or become a component of cell membranes, and the concentration of cholesterol in the blood will remain constant. When severe lesions occur in the liver, cholesterol concentrations decrease. In patients with jaundice obstruction and nephrotic syndrome, cholesterol concentrations tend to rise.

High cholesterol diet contraindications:

1. People with high cholesterol should pay attention to controlling the intake of high-cholesterol foods. The daily intake of cholesterol is controlled below 200 milligrams. Some foods such as animal offal, egg yolk, pig brain, fatty meat, crab roe, etc., these are foods rich in cholesterol, although the taste is very delicious, but you must try to control your appetite and eat as little as possible.

2. People with high cholesterol should reduce their intake of saturated fatty acids. Because some animal oils are rich in saturated fatty acids, while vegetable oils are rich in unsaturated fatty acids. Therefore, it is best not to use eating animal oil for cooking, and use vegetable oils as much as possible, such as olive oil, peanut oil, sunflower oil, etc., but among vegetable oils, coconut oil is very rich in cholesterol, so try not to eat too much.

What is cholesterol

I believe that everyone in daily life, more or less have heard of cholesterol, indeed, whether it is our daily diet, or our body itself is a certain amount of cholesterol, therefore, for everyone, cholesterol is a necessary nutrient intake, but many people do not understand this nutrient, then, let's take a look with you, what is cholesterol!

First of all, we all know that the content of cholesterol is closely related to the health of the human body, which is mainly synthesized in the human liver or obtained through the intake of some things, and also has a certain amount in the blood of the human body.

Secondly, cholesterol generally participates in the operation of a variety of physiological functions, and the human body will also consume a certain amount of cholesterol in the process of exercise, so there is a certain range of cholesterol floating in the human body, and it will be transformed and consumed with the operation of some physiological functions. It follows that there is a range of normal values for cholesterol levels.

In addition, more and more people have sub-health problems with high cholesterol, which makes many people mistakenly think that cholesterol is a bad substance, but in fact it is not, because as long as cholesterol is properly consumed, it plays a very important role in both the function and structure of the body.

Through the description of the above text, I believe that everyone has a certain understanding of cholesterol, and also realizes that cholesterol intake should not be excessive. However, the daily diet is still very worthy of everyone's attention.
