Too much cholesterol in the body can lead to hyperlipidemia. Hyperlipidemia may indeed induce hypertension, because it will increase blood viscosity and increase the accumulation of lipoprotein and fibrin on the blood vessel wall. Hypertension is often related to more reasons, such as the stenosis of blood vessel wall and the increase of sidewall pressure when blood flows through it. Vascular stenosis also has multiple causes. The aging of blood vessels, the accumulation of more lipoproteins, or the deterioration of thrombosis will greatly hinder the patency of blood vessels and cause hypertension. It may also be an uncontrolled diet, such as long-term intake of high-sugar and high-fat foods, which increases blood viscosity, provides conditions for debris accumulation and atherosclerosis on the blood vessel wall, and narrows blood vessels, causing high blood pressure; Long-term intake of high-salt food is also one of the causes of hypertension. Salt provides a large number of sodium ions, which can lead to water and sodium retention, increased blood volume, increased extravascular osmotic pressure concentration, compression of blood vessels, and lead to hypertension. In a word, we can't just attribute hypertension to hyperlipidemia.
In addition, the intake of high cholesterol food is not the main cause of hyperlipidemia. We have endogenous and exogenous cholesterol in our bodies. Exogenous cholesterol is the cholesterol we consume from food every day, accounting for a relatively small proportion, accounting for only 20%. And with the increasing intake, the absorbed amount will be lower and lower, and their influence on total cholesterol may be very weak or even negligible. Endogenous cholesterol, which accounts for more than 80% of total cholesterol, is the main source of total cholesterol, and this part is the big part that really affects the amount of cholesterol. Endogenous cholesterol secretion is related to many factors, such as liver health, genetic factors, long-term eating habits, exercise and so on. Recently, many studies have proved that there is no direct relationship between high cholesterol and the intake of high cholesterol foods. As early as 20 15, the US FDA lifted the daily cholesterol intake restriction.
In a word, eating boiled eggs is not a direct factor to induce hypertension or hyperlipidemia, but excessive intake will lead to excessive intake of protein, which will cause the burden of kidney metabolism, and it also means more intake of fat and calories, so excessive intake is not a good thing. Although exogenous cholesterol has little effect on total cholesterol, too much egg intake will also provide a small amount of cholesterol, so eating too many eggs is not recommended. Dietary guidelines recommend that an egg a day is the best choice.
Professional doctors will answer your questions.
Professional doctors tell you health every day.
This problem can be said from two aspects. First, if you were allowed to eat two or two staple foods per meal, what would you eat? The staple food is mainly foods that provide carbohydrates, such as rice noodles and coarse grains. You can choose your favorite food as the staple food, and finally get all the carbohydrates you need after digestion and absorption. In fact, the same is true of eggs. It is a kind of nutritious food, which contains a variety of nutrients that the human body needs every day. The content is not much, and it will not exceed the daily needs of the human body. Therefore, it is no problem for people with high blood pressure to eat an egg every day.
Second, the most common ingredient in eggs is cholesterol. Will these cholesterol affect blood pressure after entering the human body? In fact, this is why many people know little about how blood pressure rises and why people with hypertension should limit their cholesterol:
First of all, the increase of blood pressure is mainly due to three reasons: First, the speed of blood pumped by the heart slows down after flowing through blood vessels, and a large amount of blood stays in blood vessels for too long, which will increase the pressure on blood vessels. Because of this, this situation is often the main reason for low blood pressure, that is, increased diastolic blood pressure.
The second is the result of atherosclerosis, decreased elasticity and contractility of blood vessels and insufficient blood flow buffer. The occurrence of atherosclerosis is indeed related to the increase of cholesterol, which is caused by too much cholesterol deposited in vascular endothelium, but this deposition does not happen for no reason, but is caused by too much low-density lipoprotein cholesterol in cholesterol on the basis of vascular endothelial injury.
The cholesterol contained in eggs is not low-density lipoprotein cholesterol, it needs the body to convert the cholesterol it ingests through the liver. The human body needs to consume about 300mg of cholesterol from food every day, but an egg only contains about 250mg of cholesterol, and the absorption rate of cholesterol in food is only 30%. Therefore, only 75mg of cholesterol in an egg is absorbed into the blood, and the amount converted into low-density lipoprotein by the liver is very small, which will not lead to atherosclerosis and certainly will not affect blood pressure.
Third, due to excessive blood volume in the whole body, vascular pressure increases. More than 90% of blood is water, most of the rest are red blood cells, white blood cells, platelets and other cells, and the cholesterol is less than 1%. So eating an egg has no effect on the total blood volume at all. How can it affect blood pressure?
To sum up, it is no problem for hypertensive patients to eat a boiled egg every day. In fact, the human body is very "smart" and all systems work in harmony. For example, when the cholesterol content in the body increases, the absorption of cholesterol in food will decrease, so as to ensure that the cholesterol is not excessive as much as possible, so an egg is not enough to cause the problem of high cholesterol in the body.
The reason why hypertensive patients need to limit their cholesterol intake is because such people need to control their cholesterol content more strictly than ordinary people in order to prevent atherosclerosis, but even so, the cholesterol content in an egg is not enough to affect the control requirements, so hypertensive patients can safely eat a boiled egg, and eating it every day will not have any impact on blood pressure.
Eat too many boiled eggs, will your blood pressure be high? This question is really interesting. I heard for the first time that eating eggs can raise blood pressure. Although eating a lot of eggs every day may lead to overnutrition, obesity and metabolic disorder, which may lead to an increase in blood pressure, under normal circumstances, eating boiled eggs every day or eating boiled eggs at one time is not necessarily related to hypertension.
I often remember that when material life is not so developed, women will prepare a lot of eggs at home after giving birth to their babies. In fact, there is no way in the case of lack of materials, but for women who are weak after childbirth, eating more eggs is still a good choice for supplementing nutrition. Eggs are rich in nutrition. Egg white is rich in high-quality protein, which contains all kinds of amino acids needed by human body, and its absorption rate is as high as 90%. It is a good food source for human body to supplement protein. Egg yolk is rich in phospholipids, calcium, iron and other trace elements, as well as fat-soluble vitamins such as vitamin D and vitamin E and unsaturated fatty acids such as DHA, which is also very beneficial to supplement body nutrition.
Therefore, from the nutritional components of eggs, eggs are a very nutritious food. If you eat eggs healthily, cooking can be said to be the best cooking method. Compared with fried eggs, boiled eggs or egg soup will cause some nutritional loss of eggs, while boiled eggs can not only maintain the nutritional components of eggs, but also absorb excess oil, which is the healthiest way to eat eggs. Under normal circumstances, we eat 1~2 boiled eggs every day, which can supplement the nutritional needs of the human body in many ways, and will not cause the problem of excess energy to the body, so don't worry too much.
If you eat boiled eggs every day and happen to find that you have high blood pressure, don't let the eggs return to this pot. There are many reasons for hypertension, but it has little to do with eggs. In terms of diet, high-salt diet, eating salt every day, resulting in excessive intracellular sodium and water retention and increased blood volume, is one of the reasons for salt-sensitive hypertension. In addition, smoking is also one of the reasons. Long-term stress, metabolic syndrome, smoking and other factors are all factors that lead to high blood pressure, but eating eggs really has little to do with high blood pressure.
Many friends think that eggs, especially yolk, have high cholesterol content, which is not conducive to cardiovascular health. With the problems of high blood pressure and hyperlipidemia, they are too scared to eat eggs. Actually, it's not necessary So far, there is no relevant research. It is proved that eating eggs in patients with hypertension or hyperlipidemia will increase the risk of cardiovascular disease. The lipid components in egg yolk are partly fat-soluble vitamins and partly healthy unsaturated fatty acids such as DHA. There is also a part of lecithin that has the function of nourishing nerves. Although the cholesterol content is higher than other foods, eating an egg every day will not have a further impact on hyperlipidemia and has no adverse effect on blood pressure. A survey involving more than 20,000 people once found that people at risk of cardiovascular disease who eat an egg every day have a lower incidence of cardiovascular disease than people who don't eat eggs.
So for patients with hypertension, first of all, don't think that hypertension is caused by eggs. In the conditioning of healthy diet, eggs are also one of the healthy ingredients that can still be eaten. If you eat an egg every day, you don't have to worry about the impact of eggs on blood pressure or cardiovascular health. Compared with eating eggs, it is better to eat more light food, eat less salt, snacks, fried and high-sugar food, and strengthen physical exercise.
This statement was popular for a period of time more than ten years ago. Based on the medical level at that time, this conclusion was not questioned too much. Many doctors even often tell patients to "eat less eggs". However, with the development of medicine, people become more and more aware of the relationship between diseases and diet, and the content asked in the question is quickly labeled as a rumor.
In fact, the difference in people's diet structure and habits is only one of the important factors that induce some chronic diseases, just as people with heavy tastes are more likely to suffer from high blood pressure; The reason why there is such a statement in the title is actually considering the "cholesterol" component rich in egg yolk, because in many people's cognition, excessive cholesterol intake is an important risk factor for cardiovascular disease;
However, there is also a problem of "intake". You know, cholesterol itself is one of the main nutrients to maintain the structure and function of the body. In other words, for the smooth operation of all physiological functions of the human body, we have to consume a certain amount of cholesterol every day.
If we only rely on the supply of eggs without other sources of cholesterol, we must eat at least two eggs a day to meet the normal demand for cholesterol, but in our daily diet, whether it is meat, nuts or cooking oil, we can also provide a certain source of cholesterol for the body to some extent. In this way, one egg per person per day can supplement cholesterol very well, without worrying about its overdose, and there will be no increase in blood pressure due to eating eggs.
Eggs are one of the most common ingredients in our daily diet. They are delicious, varied and nutritious, and are deeply loved by thousands of people. Eggs are rich in high-quality protein, eight essential amino acids, lecithin, monounsaturated fatty acids, vitamin B 1, vitamin B2, vitamin A, vitamin D, calcium, iron and zinc. Each egg contains about 7 grams of protein. Protein and amino acids are in perfect proportion, second only to breast milk. Eggs are an important part of a balanced diet. Dietary Guidelines for China Residents (version 20 16) recommends eating 1 egg every day, and don't throw away the yolk, which will not increase the risk of cardiovascular disease and diabetes.
Many people are afraid to eat more eggs because they know that egg yolk is rich in cholesterol, and the cholesterol content in egg yolk is really high. Every100g of egg yolk contains about1500mg of cholesterol, and 50g of eggs contains about 300mg of cholesterol. Cholesterol is an essential nutrient for human body and an important substance that constitutes cell membrane. Cholesterol in human body is mainly divided into endogenous cholesterol and exogenous cholesterol. Self-synthesized cholesterol is endogenous cholesterol, accounting for about 70% of total cholesterol, which is the main source of cholesterol in the body. Cholesterol obtained from diet is exogenous cholesterol, accounting for about 30% of total cholesterol, and has little effect on blood cholesterol level.
Therefore, the dietary guidelines for China residents (version 20 16) abolished the restriction on cholesterol in daily diet, and the guidelines for the prevention of healthy lifestyle of cardiovascular metabolic diseases in China (version 2020) suggested that healthy adults without dyslipidemia could eat 3-6 eggs a week, and the daily intake of cholesterol for high-risk people with hypercholesterolemia and cardiovascular diseases should be less than 300mg, about/kloc-0. If you also like to eat other foods rich in cholesterol, such as animal offal, animal brain, fish eggs, crab eggs, red meat, etc., you should reduce the number of times you eat eggs every week. The research on risk prediction of atherosclerotic cardiovascular disease in China shows that eating eggs in moderation every day can reduce the incidence and mortality of cardiovascular disease.
Finally, boiled eggs are light in taste, do not need to add extra oil and salt, most of the nutrients are well preserved, easy to digest and absorb, delicious and healthy, and have little effect on blood pressure. It is suggested that patients with hypertension eat a boiled egg every day, which is beneficial to cardiovascular health. Another disadvantage of boiled eggs is that it is easy to choke if you eat too fast, especially when you eat yolk. Pay attention to chew slowly when eating, and eat with porridge, milk and soup. It should be noted that some friends with high blood pressure like to dip some soy sauce when eating boiled eggs. Soy sauce contains a lot of invisible salt, which is not conducive to the stability of blood pressure and should be avoided as much as possible.
In the morning, a hypertensive patient asked, Doctor, can't you eat eggs in the future?
I said: I didn't tell you not to eat eggs. There is no absolute taboo for high blood pressure food. Just grab the low salt. Anyone can eat it, but don't overdo it, especially foods with high salt, oil and sugar should be controlled.
The patient said: Then how can I hear people say that eating too many eggs will lead to high blood pressure?
I said: it's sheer nonsense. Eating eggs has nothing to do with hypertension. If it matters, it is that when you scramble eggs and boil eggs, too much salt will affect your blood pressure.
The patient said, I am relieved. I'm afraid I can't eat eggs.
I said: Not only can we eat, but we should also be encouraged to keep eating an egg every day, so as to ensure enough protein and nutrition and our immunity, thus reducing diseases.
We often encounter various questions from patients in the hospital, especially many people think that eating eggs will increase blood lipids and lead to cardiovascular and cerebrovascular diseases.
This view may have been right many years ago, but this rumor has long been refuted, because eating eggs will not directly lead to an increase in blood lipids, nor will it cause cardiovascular and cerebrovascular diseases.
The main component of eggs, especially yolk, is cholesterol, but it doesn't mean that eating one or two eggs every day will lead to an increase in cholesterol in our bodies. Because the rise of human cholesterol is caused by food on the one hand, that is, eating too much fat, animal offal, fried food and so on. But the effect of food on cholesterol only accounts for 25%; The other 75% is caused by self-metabolism, which has little to do with diet. Even most people don't eat foods with high cholesterol content, because of their own genetic reasons, cholesterol will also rise. This is why people usually see that they don't eat meat and are not fat, but their cholesterol will also rise.
Although eggs are high in cholesterol, they are low in saturated fat and trans fat. Studies have shown that people who eat eggs every day have a lower risk of cardiovascular disease 1 1%, ischemic heart disease 12% and hemorrhagic encephalopathy by about a quarter.
Moreover, many professional papers have recently found that eating 1-2 eggs a day will not increase the risk of heart disease for people over 60 years old with hyperlipidemia, diabetes and heart disease.
Eggs have comprehensive nutrients, and egg whites are rich in high-quality protein, riboflavin, nicotinic acid, biotin, calcium, phosphorus, iron and other substances; Egg yolk is rich in lecithin, vitamin A and vitamin D, and contains more iron, phosphorus, sulfur and calcium.
For friends with hypertension or cardiovascular and cerebrovascular diseases, as long as they are not allergic, they can eat eggs boldly and safely.
But everything is enough. Eating doesn't mean you can eat more, and you can't eat more. The reason is very simple. 1-2 eggs a day is the most scientific and healthy.
Therefore, both healthy people and friends with high blood pressure can safely eat boiled eggs!
Eating one or two eggs a day generally does not cause high blood pressure, nor does it have much impact on blood lipids. Of course, everything is the opposite. Eating too many eggs every day will definitely affect blood lipids. Blood lipids are positively correlated with blood pressure. Therefore, it is not easy to eat more eggs for hypertension, but eating eggs properly is good for hypertension.
First, the benefits of eating eggs properly in patients with hypertension are analyzed as follows.
1. The fat content in eggs is about 10%, and the proportion of monounsaturated fatty acids is relatively high, accounting for about 40%. This fatty acid is the same as the main component in olive oil, which is beneficial to maintain the normal cholesterol level of human body.
2. Egg yolk is rich in lecithin, which is a powerful emulsifier. It can make fat and cholesterol particles smaller, emulsify into fine samples suspended in blood, and be used by cells through blood vessel walls smoothly, thus reducing the cholesterol content in blood and reducing the risk of vascular sclerosis and blockage. Therefore, many scholars believe that eating eggs is not only harmless, but also has a special protective effect on the cardiovascular system.
3. Eggs also contain lutein and zeaxanthin. These two substances are antioxidants, which not only help to protect the cardiovascular system, but also play an important role in preventing macular degeneration and senile diseases.
4. Egg white helps to lower blood pressure. According to a recent press release issued by the American Chemical Society, Yu Zhipeng of Jilin University in China and others found through animal experiments that there is a peptide in egg white, which can effectively inhibit a substance called angiotensin converting enzyme, thus preventing blood pressure from rising.
The British "Daily Mail" also reported that eggs can produce protein similar to antihypertensive drugs, which has the same effect on the heart as the prescription angiotensin converting enzyme inhibitor (this drug lowers blood pressure by inhibiting angiotensin), and can lower blood pressure.
Second, how many eggs are appropriate to eat every day?
Although eggs are good, the more you eat, the better. Everything needs "moderation". Eating too much, first of all, protein intake is too much, which increases the digestive burden and kidney burden of the human body; In addition, fat intake will also exceed the standard, aggravating the original cardiovascular disease.
Adults eating an egg every day will not cause an increase in serum cholesterol levels; Even if the blood fat is high, it is ok to eat three eggs a week.
Third, boiled eggs are the most beneficial.
Finally, it is best to cook the whole egg in water. Cooking methods such as frying, frying, frying, etc. are easy to destroy the activity of lecithin and protein in eggs and make eggs lose their beneficial effects on human body.
Although eggs are good, don't eat too much. If you eat too much, it will be too late! ! !
But actually eating eggs is not the direct cause of hypercholesterolemia. Eating healthy food with high cholesterol may not have much effect on cholesterol. There are two kinds of cholesterol in our body, one is exogenous-cholesterol ingested from external food, and the other is endogenous-cholesterol secreted by ourselves (only synthesized and secreted by the liver), while exogenous cholesterol only accounts for about 20% of total cholesterol, and its absorption will decrease with the increase of intake, which will eventually have little effect on total cholesterol; Endogenous cholesterol is the main source of total cholesterol, accounting for more than 80%, but it is difficult for us to control this part of cholesterol, which depends on many factors, such as the health of the liver, our own health, genetic factors, daily comprehensive diet, living habits and so on.
Because the effect of exogenous cholesterol on total cholesterol is actually very small, the FDA of the United States also cancelled the daily cholesterol intake of residents on 20 15. However, this does not mean that "unhealthy food with high cholesterol" (such as fried food, processed food and food with high content of hydrogenated vegetable oil) can be ingested unscrupulously. However, we can actually eat more healthy foods containing cholesterol. For example, many people in the United States do eat five or six eggs a day, which ultimately has little effect on cholesterol and is not an inducing factor of hypertension.
Many latest theories prove that cholesterol intake from food is not the main factor affecting blood cholesterol, but hypercholesterolemia is related to comprehensive factors such as our long-term uncontrolled diet (such as overeating, excessive intake of foods high in oil, fat and sugar). In a word, we don't need to worry that the cholesterol taken from eggs will have a great influence on the total cholesterol. Even if the cholesterol content in an egg is as high as 280mg, it may eventually be absorbed only a little. Hypercholesterolemia is also related to its own low density lipoprotein (LDL) and high density lipoprotein (HDL). If LDL is high, the total amount of cholesterol circulating in the blood will increase, while raising blood lipid or lowering HDL will also reduce the amount of glycerol monostearate metabolized to the liver in the blood, thus affecting the total cholesterol content and causing hypercholesterolemia. Obesity, lack of exercise and sitting for a long time all easily affect the amount of HDL. Excessive intake of processed foods will lead to excessive intake of hydrogenated oils from plants, which in turn will lead to excessive intake of "trans fatty acids". Trans fatty acids can increase the amount of LDL and also cause hyperlipidemia. Cholesterol rich in eggs is more likely to increase HDL content, but it is helpful to health.
However, eating too many eggs is not recommended. One egg a day is enough. Although eggs are foods with high nutritional value, they contain high-quality protein after all. Eating too much will put a burden on kidney metabolism. In addition, eggs feel full and you may miss other rich nutrients.
Before answering this question, what are the causes of hypertension?
The increase of blood pressure here generally refers to the increase of primary blood pressure, and the possible reasons for the increase of blood pressure are as follows: ① Overweight and obese patients (especially those with large bellies are prone to increase blood pressure).
② Heredity.
③ Excessive salt intake or long-term consumption of foods with high salt content, diets with insufficient calcium and potassium intake, diets with high animal and vegetable protein and diets with high animal fat.
4 Long-term work stress or long-term mental stress.
⑤ Sleep apnea hypopnea syndrome.
6 Long-term oral contraceptives (especially female friends after the age of 35).
Back to the question, eating too many boiled eggs will lead to an increase in blood pressure. Eggs are rich in protein and cholesterol. Eggs have high nutritional value and are loved by most people. Eating eggs in moderation can supplement protein. These protein can improve the amino acids people need, and choline supplementation can improve people's memory.
Eggs belong to a high protein and high cholesterol diet. Long-term consumption of boiled eggs will lead to excessive intake of protein, increase the burden on the gastrointestinal tract and kidneys, and cause gastrointestinal diseases. Second, it will lead to excessive cholesterol intake, abnormal blood lipids, obesity and atherosclerosis. These two factors will not only lead to hypertension, but also cause gastrointestinal diseases and cardiovascular and cerebrovascular diseases.
Conclusion: Although eggs are good, you should not eat too much. In order to ensure a balanced nutrition, it is recommended that eggs be eaten with other diets. People engaged in mental and light manual labor had better not eat more than two eggs a day, and people engaged in heavy manual labor had better not eat more than three eggs a day.
First, let's look at the causes of hypertension. Hypertension is mostly primary hypertension, but the reason is not clear. The main diseases are genetic factors and environmental factors (eating habits and mental stress). At present, it is believed that it is caused by polygene inheritance, and 30% ~ 50% of hypertensive patients have genetic background. Long-term mental stress, excitement, anxiety, noise or bad visual stimulation can all induce hypertension. The main dietary factors are unreasonable dietary structure, such as excessive sodium and salt, low potassium diet, excessive drinking and excessive intake of saturated fatty acids. Obviously, boiled eggs are not included.
About 5% patients with hypertension are secondary hypertension, which is caused by some diseases or reasons. Such as primary aldosteronism, pheochromocytoma and renin secreting tumor.
Let's look at the nutritional composition of eggs. Eggs are an important part of our daily life. Eggs are rich in protein, carbohydrates, cholesterol, calcium, zinc, copper, manganese, vitamin A, vitamin B2, nicotinic acid, selenium and other nutrients. Moreover, the protein species and amino acid composition ratio of eggs are perfect, which is beneficial to human absorption.
People used to think that egg yolk contains more cholesterol, and eating eggs often will lead to an increase in blood lipids and promote the occurrence of atherosclerosis. Therefore, some people advocate that the elderly should eat less or not eat eggs. However, in recent years, studies have shown that eating eggs can not only increase blood lipids, but also lower cholesterol and prevent diseases such as atherosclerosis, coronary heart disease and stroke.
The content of cholesterol in egg yolk is really high, and the cholesterol in an egg yolk is about 280 mg. Cholesterol in our body is endogenous and exogenous. Exogenous is the cholesterol we consume from food every day, accounting for only 20%. And with the increasing intake, the absorption will be lower and lower, and their influence on total cholesterol is very weak. Foods such as cereals, beans, vegetables and fruits can also inhibit the absorption of cholesterol in the intestine. Under normal circumstances, when the cholesterol absorbed by the intestine increases, the amount of cholesterol synthesized in the liver will decrease, thus maintaining the relative balance of cholesterol in the blood.
Egg yolk is also rich in lecithin, which is a strong emulsifier. When it is absorbed into the blood, it can make cholesterol particles smaller and remain suspended. This not only helps cholesterol to be utilized by tissues through the blood vessel wall, but also avoids the deposition of cholesterol on the blood vessel wall, thus helping to lower cholesterol.
So there is no evidence that eggs will raise blood pressure and blood lipids. It is recommended to boil an egg every day, eat less fried eggs or fried eggs, and avoid excessive intake of oil and salt.
