In fact, most experiments have confirmed that onions have the effect of lowering blood pressure. Some researchers asked the experimenters to drink a cup of standard onion juice every day, and found that after drinking onion juice 1, 2 and 3 months, the blood pressure of the experimenters was lower than before the experiment [1]. By intragastric administration of onion extract to SD rats, it was found that onion extract could instantly reduce the blood pressure of normal rats and hypertensive rats [1]. This is mainly because there is quercetin in onions. Epidemiological and clinical trials have found that the intake of flavonoids in diet is helpful to reduce the risk of cardiovascular diseases, which may be related to its antioxidant and anti-inflammatory effects. Quercetin is a kind of phytochemicals with the strongest antioxidant effect among flavonoids, and onion is the main food source of its daily diet. At the same time, onion also contains prostaglandin A, which can dilate and soften blood vessels and regulate lipid metabolism. Onion is the only vegetable known to contain prostaglandin A. It can be seen that onion can lower blood pressure, which is scientifically based.
Can eating more onions replace taking antihypertensive drugs? In fact, some researchers have put forward a prescription for lowering blood pressure with onion as the main raw material [2], but this prescription has a special treatment method and a course of taking onion, and it is better to eat it in the early stage of hypertension. Generally speaking, the effective components of onion can not be fully dissolved at home, and high temperature will destroy the effective components, which can not be quantified. The medicine prescribed by doctors is the most scientific treatment method, which is based on the strict monitoring of many indicators by researchers through a large number of experiments. Therefore, eating onions can only help lower blood pressure and cannot directly replace drugs. Hypertensive patients still have to listen to the doctor's advice and take medicine on time in order to restore their health more scientifically.
Is onion better eaten raw or cooked? If onions are eaten for health care, it is recommended to eat them raw. Because high temperature is easy to destroy some nutrients and effective ingredients, raw food can play a variety of roles. If there are no special requirements, generally speaking, white onions are best eaten raw, because white onions contain a lot of vitamin C and carotene, so they taste a little sweet; Purple onion has a high content of protein and minerals, which is a little spicy and suitable for frying [3].
In short, eating onions has the effect of lowering blood pressure, but eating onions can not directly replace taking antihypertensive drugs. In daily life, you can eat appropriate amounts of onions for adjuvant treatment. How to eat onions can be chosen according to your own hobbies.

Onions are good news for patients with hypertension.
Onion contains a variety of phytochemicals, such as sulfur compounds, flavonoids, phenylpropanoids, steroidal saponins and prostaglandins, etc., which have the effects of antioxidation, antiplatelet, blood lipid lowering, blood pressure lowering and weight control, and are conducive to reducing the risk of cardiovascular diseases. Onion contains prostaglandin A, which is a natural blood thinner. Prostaglandin A can dilate blood vessels, reduce blood viscosity and lower blood pressure. The tear-causing substance of onion is cyclic alliin, which contains sulfide and can reduce the viscosity of platelets. Onion is rich in vitamin C, carotene and other vitamins, and has antioxidant activity. Dietary fiber can reduce blood sugar, blood cholesterol and blood lipid levels.
Onion, known as the "queen of vegetables", is rich in nutritional value and deeply loved by the public. Related research shows that onion contains prostaglandin A, which can dilate blood vessels and reduce blood viscosity. At the same time, eating onions often can also regulate human blood lipids. Generally speaking, onion has a certain auxiliary effect on the treatment of patients with hypertension.
We suggest that patients with hypertension eat 50~80g onion (equivalent to one onion) every day, which can be soaked in vinegar or wine or cooked. It should be noted that for patients with eye diseases, liver diseases and gastrointestinal diseases, try to eat less onions.
Although onion can regulate blood pressure to some extent, it is food, not medicine. This ability to regulate blood pressure is too weak to replace antihypertensive drugs. Therefore, patients with hypertension can only use onions as a diet. Everyone still needs to actively improve their lifestyle and take antihypertensive drugs regularly in order to stabilize blood pressure and reduce complications of target organs such as heart, brain and kidney.
Patients with hypertension should pay attention to low-salt diet, quit smoking and limit alcohol, exercise properly, control weight, work and rest regularly, and maintain a good attitude in daily life. They should also pay attention to the use of antihypertensive drugs under the guidance of doctors, and the drugs should be individualized. At the same time, in daily life, we should pay attention to monitoring the changes of blood pressure level and review it regularly, so as to control blood pressure stably and improve the quality of life.

Eating onions in patients with hypertension can help prevent blood pressure from rising. But also pay attention to the following points:
Hypertension complicated with diabetes, asthma and insomnia should be eaten for a long time. Patients with skin pruritus should eat less or not as much as possible.
Science popularization has been going on for almost a year, and my ability is too limited. Every day, so many people ask what food can lower blood pressure!
It is the dereliction of duty of our popular science workers!
Cut an onion and study it, and shed some tears as punishment.
Popular science may have to be repeated, because only repetition can let more people see the facts. Of course, we also need the support of the platform, because the platform can decide to let more people see the truth!
Onions not only can't lower blood pressure, but also have not found any food to lower blood pressure!
Do you see it? Theoretically! In fact, the content of prostaglandin A in an onion is so small that it is impossible for us to rely on onions to lower blood pressure. If you really rely on onions to lower your blood pressure, I don't know how many onions to eat.
All the vegetables that claim to lower blood pressure, but in theory, in real life, the effective ingredients contained in the vegetables we eat have no antihypertensive effect at all.
Onions are just ordinary vegetables. When they are cut, they will cry. It's a little spicy when eaten raw, and many people can't get used to this taste.
That's all. We suggest eating more fresh vegetables, including onions.
Eating onions for a long time is good for preventing hypertension and stabilizing blood pressure, which may be the relationship between onions and hypertension!
The purpose is not to lower blood pressure directly, but to eat healthy and be healthy!
Onion does have the effect of lowering blood pressure, because onion is the only vegetable containing prostaglandin A, which can dilate blood vessels and reduce blood viscosity, thus lowering blood pressure, increasing coronary blood flow and preventing thrombosis.
In addition to the above nutrients, the leaf top of green onion is a good source of potassium and vitamin A and vitamin C. As we all know, contrary to the effect of sodium salt, potassium can help lower blood pressure, which is one of the most important theoretical sources to promote the intake of enough vegetables and fruits every day to help lower blood pressure. The guidelines of major nursing schools recommend eating at least 500 grams of fresh vegetables and 250 grams of fruit every day.
Onions contain plants and fungicides, such as allicin, so they have strong bactericidal ability. Chewing raw onions can prevent colds. In addition, the trace element selenium contained in onion is a strong antioxidant, which can help remove free radicals in the body, increase the vitality and metabolism of cells, and also has certain anti-cancer and anti-aging effects.
However, it should be noted that do not eat onions excessively, because onions are easy to produce volatile gases, which will cause flatulence and excessive exhaust, giving people an uncomfortable feeling. Recommended, each meal should be less than one or two.
Although onions have many beneficial effects, it should not be exaggerated that patients with hypertension can obviously lower their blood pressure by eating onions, which is only the basis of a healthy lifestyle.
Patients with hypertension can eat onions. Onion is rich in antioxidants, which can effectively inhibit the process of atherosclerosis, and has an auxiliary therapeutic effect on cardiovascular and cerebrovascular diseases such as hypertension and coronary heart disease.

Can hypertension eat onions?
Can eat
Patients with hypertension can eat onions, which are nutritious and beneficial to patients with hypertension. Patients with hypertension should eat foods with less salt, not foods with more sodium. Onion can promote sodium digestion, thus changing blood pressure in the body, which can play a certain role in lowering blood pressure. Therefore, eating more onions is very beneficial to patients with hypertension, which can not only lower blood pressure, but also supplement other nutrients.
Eat more onions to prevent hypertension.
Onions were introduced into China for a short time, probably from abroad in the early 20th century. I remember that there was always onion salad or mixed noodles at home, especially in hot summer, and there was a lot of sweet and spicy juice. It's delicious, but now I know its dietotherapy and health care function.
First of all, let's talk about its blood pressure lowering function. Onion is the only plant containing prostaglandin A, and it is a natural blood thinner. What substance is prostaglandin A? It can dilate blood vessels and reduce blood viscosity, thereby lowering blood pressure, reducing peripheral blood vessels, increasing coronary blood flow and preventing thrombosis. It can resist the action of pressor substances such as catecholamine in human body, promote the excretion of sodium salt, and thus lower blood pressure. Regular consumption has a health care effect on patients with hypertension, hyperlipidemia and cardiovascular and cerebrovascular diseases.
Chinese medicine's understanding of onion is: sweet, slightly pungent, warm in nature, entering the liver, spleen, stomach and lung meridians; Has the effects of moistening intestine, regulating qi and regulating stomach, invigorating spleen, promoting digestion, dispelling cold, warming yang, promoting digestion, refreshing, removing blood stasis, and removing toxic substances. Can be used for treating exogenous wind-cold, anhidrosis, nasal congestion, dyspepsia, insomnia, hypertension, hyperlipidemia, dysentery, etc.
Therefore, friends with high blood pressure and cardiovascular and cerebrovascular problems can often eat onions and black fungus. Cold dishes are the best, such as cold onions and black fungus. If you feel that cold salad is irritating to your stomach and heartburn, you can fry onions before eating.
But good things should also be used dialectically. Onions should not be eaten too much at a time, which is easy to cause eye paste and fever. At the same time, people with itchy skin, eye diseases, stomach diseases and lung and stomach inflammation should eat less. At the same time, onions are spicy and warm. Patients with fever should be careful to eat the spicy taste of onions, which is irritating to the eyes. When suffering from eye diseases and bloodshot eyes, it is not advisable to cut onions.
Other influences
Flavonoids from Dendrobium bark contained in onion have estrogen-like effects, which are comparable to female hormones or osteoporosis drugs. It has been reported that eating 200-300 grams of onion every day can effectively prevent osteoporosis.
Onions also contain a certain amount of calcium. In recent years, Swiss scientists have found that eating onions regularly can improve bone density and help prevent osteoporosis.
Stir-fried onions can strengthen bones and supplement calcium. We can also find onions in western food, salads and hamburgers. Onion is known as "the queen of vegetables" in Europe and America. Onion can also prevent high cholesterol, decompose fat, prevent gastric cancer, fight asthma, treat diabetes, prevent insomnia and nasal congestion.
Onion taboo
1. Onions should not be eaten too much at a time, which may cause eye paste and fever.
2. People with itchy skin, eye diseases, stomach diseases and lung and stomach inflammation should eat less.
3. Onion is pungent, warm, and should be used with caution for patients with fever.
4. The spicy taste of onion irritates eyes. When suffering from eye diseases and bloodshot eyes, it is not advisable to cut onions.
5. People with lung and stomach heat, yin deficiency and blindness should use onions with caution.
Hello, thank you for your question! Studies have shown that onions have a certain antihypertensive effect and are good for the body.
Onion is called "the queen of vegetables" and is an indispensable food in the diet. It is not only cheap and delicious, but also rich in various nutrients needed by the human body, which has a significant effect on lowering blood pressure. It is an edible functional healthy vegetable, and it can also prevent various cancers for healthy people.
Onion is rich in nutrients such as potassium, vitamin C, folic acid, zinc, selenium and fiber, among which quercetin and prostaglandin A are special, which makes onion more valuable and has many irreplaceable health care functions.
Onion has a good preventive effect on "three highs" and other "rich diseases", and its rich xanthuric acid and butyric acid can make cells make better use of sugar, thus reducing blood sugar; Rich prostaglandin can dilate blood vessels, reduce peripheral vascular resistance, promote sodium excretion and reduce elevated blood pressure; A small amount of raffinose can proliferate human bifidobacteria, and play a role in relaxing bowels, lowering blood fat and blood pressure.
In addition, onion is a natural blood thinner, which can reduce blood viscosity, soften blood vessels, prevent thrombosis, enhance metabolism, resist aging and prevent osteoporosis.
But! Eating too much onion is easy to get angry, and diet can only be used as an auxiliary treatment, not as the main way to reduce blood pressure. It is suggested that the effect of combined medication will be better.
Thank you for your question, I hope I can help you!
Eating onions can lower the blood pressure of patients with hypertension. Onion is rich in nutrition, which can not only lower blood pressure but also lower blood sugar, resist cancer and bacteria, promote digestion and prevent osteoporosis.
Next, "Ask the doctor" will give you a detailed introduction of how onions can lower blood pressure, other functions of onions and some suggestions for hypertensive patients to eat onions, hoping to solve your doubts.
Why can onions lower blood pressure? Onions contain prostaglandin A, which is rare in other vegetables. It can directly act on blood vessels, make blood vessels dilate normally, reduce blood viscosity, and thus lower blood pressure.
Prostaglandin A is a strong vasodilator, which can activate the active components of hemolytic fibrin, reduce the resistance of human peripheral blood vessels and coronary arteries, and promote the excretion of sodium salts and other substances that cause hypertension, thereby lowering blood pressure and preventing thrombosis.
Besides lowering blood pressure, what role does onion have?
How to make onion have the most obvious antihypertensive effect? To make onions have a better antihypertensive effect, hypertensive patients can follow the following suggestions in their daily lives:
(1) Try to buy purple onions, which contain more antioxidant anthocyanins and have a better antihypertensive effect.
(2) Eating raw onions has high nutritional value, and cooking methods such as steaming, boiling and frying will destroy the nutritional components in onions. The practice of mixing onions with fungus can not only maintain the value of onions, but also will not affect the taste.
(3) It is best not to dip onions in the sauce, because the salt content of the sauce is very high, which is not conducive to controlling blood pressure in patients with hypertension.
(4) It is recommended that patients with hypertension eat 30- 120g onion every time, which is about half an onion.
Although onion is rich in nutritional value, it should not be eaten too much, because it is easy to produce volatile gases, which will make people flatulence or exhaust, making people uncomfortable.
Tip: Although onion has a good blood pressure lowering effect, it is unscientific to lower blood pressure only by a certain food. Patients with hypertension should follow the doctor's advice and take antihypertensive drugs on time.
